Frage 1 Bericht
In a school setting, what is a key safety practice during emergency drills?
Antwortdetails
During an emergency drill in a school setting, the key safety practice is staying calm and following the instructions given by teachers. Panic leads to disorganised movement, which increases the risk of injuries such as falls, stampedes, and bottlenecks at exits. Teachers are trained to direct students along designated evacuation routes, account for every student at assembly points, and manage the orderly flow of people out of the building.
The other options describe behaviours that compromise safety during an emergency:
Frage 2 Bericht
Which of the following is NOT an objective of health education?
Antwortdetails
Health education is the process of providing individuals and communities with the knowledge, skills, and motivation to make informed decisions about their health. Its recognised objectives include:
Diagnosing medical conditions is NOT an objective of health education. Diagnosis is a clinical function performed by trained medical professionals such as doctors, nurses, and laboratory scientists. It requires physical examination, medical history, diagnostic tests, and clinical judgement, none of which fall within the scope of health education.
Health education empowers people to recognise symptoms and seek appropriate medical help, but it does not equip or authorise them to diagnose diseases. Confusing health education with clinical diagnosis is a common misconception. Health educators teach prevention and health promotion; healthcare providers diagnose and treat.
Frage 3 Bericht
Which somatotype is prone to developing poor posture due to excess body weight and lower muscle tone?
Antwortdetails
The three primary somatotypes, classified by William Sheldon, describe body composition tendencies:
The endomorph somatotype is the one most prone to developing poor posture due to excess body weight and lower muscle tone. The additional weight, especially around the abdomen and trunk, shifts the centre of gravity forward, which can cause excessive lumbar lordosis (an exaggerated inward curve of the lower back). The relatively lower muscle tone means the postural muscles (core, back extensors, and hip flexors) may not be strong enough to counteract this gravitational pull, leading to slouching, rounded shoulders, and other postural deviations.
Ectomorphs, being lean and light, do not carry excess weight that would strain posture. Mesomorphs typically have strong musculature that supports good postural alignment. The option suggesting all types are equally prone is incorrect because the specific combination of excess fat and lower muscle tone makes endomorphs distinctly more susceptible.
Frage 4 Bericht
What is the importance of having qualified officials and referees in national sports competitions?
Antwortdetails
Qualified officials and referees are essential in national sports competitions because their primary responsibility is to enforce the rules of the game impartially and uphold the integrity of the competition. They are trained to interpret and apply the laws of the sport consistently, make fair judgements on fouls, violations, and scoring, and ensure that all participants compete on a level playing field.
Without qualified officials, competitions would lack credibility. Biased or uninformed officiating would undermine public trust, discourage fair play, and potentially endanger athletes. Qualified referees also help maintain player safety by penalising dangerous play and enforcing protective rules.
The other options describe roles that do not belong to officials. Managing team logistics and athlete accommodations is the job of team managers and event organisers. Encouraging spectators falls to cheerleaders, fans, and event promoters. Promoting the sport's image through media is handled by public relations and marketing personnel. None of these are officiating functions.
Frage 5 Bericht
In the discus throw, what is a key element of the athlete's technique?
Antwortdetails
A key element of the discus throw technique is using a spinning motion to build angular momentum before the release. The thrower stands at the back of a circular throwing ring (2.5 metres in diameter) and performs a rotational movement - typically one and a half turns - across the ring before releasing the discus. This spinning technique converts rotational speed into the linear velocity of the discus at the moment of release, maximising throwing distance.
The spin generates angular momentum, which is the rotational equivalent of linear momentum. The faster and more controlled the rotation, the greater the speed at which the discus leaves the hand. The thrower also uses a wide sweeping arm path to increase the radius of rotation, further boosting release velocity.
The other options describe techniques that are incorrect for discus:
Frage 6 Bericht
Which phase comes right after the reaction time in sprinting?
Antwortdetails
In sprinting, the phase that comes immediately after the reaction time is the drive phase. The sequence of a sprint race is:
There is no "relaxation phase" as a formal phase of sprinting. While sprinters must keep their upper body relaxed during the race to avoid wasting energy, this is a technique cue, not a named phase.
Frage 7 Bericht
Which of the following is an example of a healthy fat source for an athlete?
Antwortdetails
Dietary fats are essential for athletes because they provide a concentrated energy source, support hormone production, aid absorption of fat-soluble vitamins (A, D, E, K), and help protect vital organs. However, the type of fat consumed matters significantly for health and performance.
Avocados and nuts are rich in unsaturated fats, specifically monounsaturated and polyunsaturated fatty acids. These fats help reduce LDL ("bad") cholesterol, support cardiovascular health, and provide anti-inflammatory benefits that aid recovery from exercise. Nuts also supply protein, fibre, and micronutrients such as magnesium and zinc.
The remaining options predominantly contain saturated and trans fats. Fried foods and pastries are typically cooked in oils that produce trans fats, which raise LDL cholesterol and lower HDL ("good") cholesterol. Margarine and processed snacks often contain partially hydrogenated oils, another source of trans fats. Butter and red meat are high in saturated fat, which in excess is linked to increased cardiovascular risk. While small amounts of saturated fat are acceptable in a balanced diet, these sources are not considered healthy primary fat choices for athletes.
Frage 8 Bericht
What role does the hypothalamus play in the central nervous system?
Antwortdetails
The hypothalamus is a small but vital region of the brain located below the thalamus and above the pituitary gland. Within the central nervous system, it serves as the primary control centre for homeostasis - maintaining the body's internal environment within stable limits. Its key regulatory roles include controlling body temperature (thermoregulation), hunger and satiety, thirst, sleep-wake cycles, and certain emotional responses. It also acts as the link between the nervous system and the endocrine (hormonal) system by directing the pituitary gland.
The other options describe functions controlled by different brain regions:
Frage 9 Bericht
How does aerobic energy contribute to track events?
Antwortdetails
The body uses two main energy systems during physical activity: the aerobic (with oxygen) and anaerobic (without oxygen) energy systems. In track events, the dominant system depends on the duration and intensity of the event.
Aerobic energy is produced when the body uses oxygen to break down carbohydrates and fats for fuel. This process is slower but can sustain energy production for extended periods. It is the primary energy system for long-distance events such as the 800m, 1500m, 5000m, 10000m, and marathon.
In long-distance track events, the body cannot rely on anaerobic energy alone because anaerobic reserves (ATP-PC and lactic acid systems) are depleted within seconds to minutes. The aerobic system takes over to provide a continuous, sustained energy supply through oxidative metabolism.
The other options are incorrect:
Frage 10 Bericht
Which mental health habit supports good personal health?
Antwortdetails
Seeking support when feeling overwhelmed is a positive mental health habit that supports good personal health. When stress, anxiety, or emotional difficulties become difficult to manage alone, reaching out to trusted friends, family members, counsellors, or mental health professionals provides an outlet for expressing feelings, gaining perspective, and developing coping strategies. This is a recognised component of emotional well-being and resilience.
The other options describe behaviours that are harmful to mental and personal health:
Frage 11 Bericht
In precolonial Nigeria, wrestling served primarily as:
Antwortdetails
In precolonial Nigeria, wrestling was far more than a simple sport. It served as a cultural, social, and physical training activity deeply embedded in community life across many ethnic groups, including the Igbo, Yoruba, Hausa, and Tiv peoples.
The other options are incorrect. Wrestling was indigenous to Nigerian communities, not imported. It held deep community significance and was not a casual pastime. While wrestling sometimes had spiritual dimensions, it was not purely a religious ritual, and it clearly involved substantial physical benefits.
Frage 12 Bericht
Which muscle is the largest in the human body?
Antwortdetails
The gluteus maximus is the largest muscle in the human body by both mass and volume. Located in the buttock, it forms the bulk of the gluteal region and is the most superficial of the three gluteal muscles (gluteus maximus, medius, and minimus). Its primary functions are hip extension (straightening the hip joint when standing up from a seated position, climbing stairs, or sprinting) and external rotation of the thigh. It is essential for maintaining an upright posture and generating powerful movements of the lower body.
The other options, while large muscles, are not the largest:
Frage 13 Bericht
What is the most effective method for a community to reduce the amount of waste sent to landfills?
Antwortdetails
Waste management is a critical environmental and public health concern. Among the strategies available, practising the "3 Rs" - Reduce, Reuse, and Recycle - is the most effective method for a community to minimise the amount of waste sent to landfills.
This approach tackles waste at multiple levels - from prevention to recovery - making it far more comprehensive than the alternatives.
Burning waste in an incinerator reduces volume but creates air pollution and toxic ash. Burying waste in a landfill is the very problem the question asks about solving. Simply throwing waste in a public bin does not reduce the total waste; it merely collects it in one place before it goes to a landfill. None of these alternatives addresses the root cause of waste generation the way the 3 Rs framework does.
Frage 14 Bericht
A student misuses an opioid painkiller by taking a higher dose than prescribed. What is a serious and immediate effect
this can have on the body?
Antwortdetails
Opioid painkillers (such as morphine, codeine, tramadol, and fentanyl) act on opioid receptors in the brain and brainstem. At prescribed doses they relieve pain, but at higher-than-prescribed doses they overstimulate these receptors, causing respiratory depression - a dangerous slowing or cessation of breathing.
The brainstem contains the respiratory centre that automatically controls the rate and depth of breathing. Opioids suppress this centre in a dose-dependent manner: the higher the dose, the greater the suppression. In severe cases, breathing can slow to the point where the body no longer receives enough oxygen, leading to hypoxia, loss of consciousness, and potentially death. This is the primary mechanism by which opioid overdoses are fatal.
The other options describe effects that are the opposite of what opioids actually do:
Frage 15 Bericht
A person who exercises regularly is more likely to have a lower risk of falls as they age due to improvements in which
two fitness components?
Antwortdetails
Regular exercise reduces the risk of falls in older adults primarily by improving flexibility and muscular strength.
The other pairs are less directly linked to fall prevention:
Frage 16 Bericht
Which of the following is a key phase in the long jump?
Antwortdetails
The long jump consists of four recognised phases: the approach run, the takeoff, the flight (or air phase), and the landing. The approach run is a key phase in which the athlete sprints down the runway to build up maximum controllable speed before reaching the takeoff board. The speed generated during the approach run directly determines the horizontal distance the athlete can achieve, making it one of the most critical phases of the event.
The other options describe actions that are not standard long jump phases:
During the approach run, consistency is vital. Athletes use check marks on the runway to ensure they hit the takeoff board accurately at full speed without fouling.
Frage 17 Bericht
What is a major challenge that both NIPOGA and NATCEGA often face?
Antwortdetails
NIPOGA (Nigerian Polytechnic Games Association) and NATCEGA (Nigerian Colleges of Education Games Association) are bodies that organise inter-institutional sports competitions for polytechnic students and college of education students in Nigeria, respectively.
Both organisations frequently face the challenge of poor funding, inadequate sports facilities, and logistical issues. These problems are interrelated:
The other options do not accurately describe the challenges. Finding a host institution is generally not the primary difficulty. Lack of interest is not a major problem, as student-athletes are typically eager to participate. Having too many athletes wanting to participate would be a positive problem rather than a challenge, and it is not the core issue these bodies face.
Frage 18 Bericht
What is the function of the valves within the heart?
Antwortdetails
The heart contains four valves - the tricuspid, pulmonary (semilunar), mitral (bicuspid), and aortic (semilunar) valves. Their primary function is to prevent the backflow of blood, ensuring that blood moves in one direction through the heart's chambers and into the great vessels.
When the ventricles contract (systole), the atrioventricular valves (tricuspid and mitral) snap shut to prevent blood from flowing back into the atria. When the ventricles relax (diastole), the semilunar valves (pulmonary and aortic) close to prevent blood from flowing back into the ventricles from the arteries. This one-way flow is essential for efficient circulation.
The other options describe different structures or misattribute functions. Electrical impulses that regulate the heartbeat are produced by the sinoatrial (SA) node, not the valves. The septum - a muscular wall - is what separates oxygenated blood on the left side from deoxygenated blood on the right side. While the closing of the valves does produce the characteristic heart sounds ("lub-dub"), producing sound is not their function; it is merely a by-product of their mechanical action.
Frage 19 Bericht
A deficiency in calcium can lead to a condition in which bones become brittle and fragile, a condition known as:
Antwortdetails
Calcium is the most abundant mineral in the human body and is critical for maintaining strong, dense bones. When the diet is chronically deficient in calcium, the body draws calcium from the bones to maintain blood calcium levels needed for nerve signalling, muscle contraction, and heart function. Over time, this depletes bone mineral density, making bones porous, brittle, and fragile - a condition known as osteoporosis. Osteoporosis significantly increases the risk of fractures, particularly in the hip, spine, and wrist.
The other conditions are caused by entirely different nutritional deficiencies:
Exam tip: Link calcium to bones and osteoporosis; link iodine to thyroid and goitre; link B-vitamins to their specific deficiency diseases (B1 = beriberi, B3 = pellagra, B12 = anaemia).
Frage 20 Bericht
Which organelle modifies, sorts, and packages proteins for secretion or use within the cell?
Antwortdetails
The Golgi apparatus (also called the Golgi complex or Golgi body) is a membrane-bound organelle that functions as the cell's processing, packaging, and distribution centre for proteins and lipids. After proteins are synthesised by ribosomes and initially folded in the endoplasmic reticulum (ER), they are transported in vesicles to the Golgi apparatus, where they undergo further modification (such as glycosylation - the addition of sugar groups), sorting, and packaging into vesicles for delivery to their final destinations. These destinations include the cell membrane (for secretion), lysosomes, or other organelles.
The other organelles serve different functions:
Frage 21 Bericht
Why is water important for digestion?
Antwortdetails
Water plays several essential roles in the digestive process, but its most direct contributions are softening stool and aiding in nutrient absorption.
During digestion, water acts as a solvent that dissolves nutrients (such as vitamins, minerals, glucose, and amino acids) so they can be absorbed through the walls of the small intestine into the bloodstream. In the large intestine, water is absorbed into the faecal matter, keeping stools soft enough to pass comfortably. Without adequate water intake, stools become hard and dry, leading to constipation.
The other options are inaccurate:
Frage 22 Bericht
The scope of physical education includes health-related fitness. What does this primarily focus on?
Antwortdetails
Health-related fitness, as a component within the scope of physical education, primarily focuses on the ability to perform daily tasks with vigour and without undue fatigue. This definition comes from the concept of physical fitness as functional capacity - being fit enough to carry out everyday activities (walking, climbing stairs, lifting objects, working) effectively while still having energy reserves for leisure activities and emergencies.
Health-related fitness comprises five components:
The other options describe different aspects of physical education or sport:
Frage 23 Bericht
Which muscle is known as the "six-pack" muscle?
Antwortdetails
The rectus abdominis is the muscle commonly known as the "six-pack." It is a long, flat muscle that runs vertically along the front of the abdomen, from the pubic bone to the sternum and lower ribs. Tendinous intersections (bands of connective tissue) cross the muscle horizontally, creating the segmented "six-pack" appearance when body fat is low enough for the muscle to be visible.
The rectus abdominis is responsible for flexing the lumbar spine (bending the trunk forward), compressing the abdominal contents, and assisting in forced expiration and stabilising the pelvis during movement.
The other muscles listed are distinct:
Frage 24 Bericht
Which of the following is a key characteristic of 'rest'?
Antwortdetails
Rest is defined as a time of conscious or unconscious inactivity that allows the body and mind to recover. During rest, the body repairs tissues, replenishes energy stores, and restores physiological balance. Rest can be conscious (sitting quietly, relaxing while awake) or unconscious (sleep). It is a passive state characterised by minimal physical and mental exertion, and its primary purpose is recovery from the demands of daily activity, exercise, or work.
The other options describe different concepts:
In physical education, understanding the distinction between rest, recreation, leisure, and work is important. Rest is unique because it is the only one defined by inactivity and recovery rather than by purposeful engagement.
Frage 25 Bericht
Which of the following is an example of visual pollution?
Antwortdetails
Visual pollution (also called aesthetic pollution) refers to anything that negatively affects the visual appearance of an environment, making it unpleasant or unattractive to look at. Litter scattered across public parks is a clear example because it degrades the natural beauty and aesthetic quality of an outdoor space, creating an eyesore for visitors.
The other options represent different types of environmental pollution:
Visual pollution includes litter, graffiti, abandoned buildings, poorly placed billboards, and uncontrolled dumping. The key distinction is that visual pollution is identified by its impact on what people see in their environment, rather than what they hear, breathe, or drink.
Frage 26 Bericht
Which of the following is a symptom of drug withdrawal?
Antwortdetails
Drug withdrawal refers to the set of physical and psychological symptoms that occur when a person who has developed dependence on a substance suddenly reduces or stops using it. The body, having adapted to the regular presence of the drug, reacts adversely when it is no longer available.
The characteristic symptoms of withdrawal include cravings (an intense desire to take the drug again), sweating, tremors (involuntary shaking), and anxiety. Other common symptoms may include nausea, irritability, insomnia, muscle aches, and in severe cases, seizures. These symptoms arise because the nervous system has adjusted its neurotransmitter levels to compensate for the drug's presence, and removing the drug leaves the system in an unbalanced state.
The remaining options describe the opposite of what occurs during withdrawal. Increased appetite and feeling well-rested, a sudden increase in energy and euphoria, or feelings of calm and relaxation would suggest the body is comfortable without the drug. In reality, withdrawal is a distressing experience that often drives people back to drug use, which is why supervised medical detoxification is recommended for individuals with substance dependence.
Frage 27 Bericht
Which of the following is a skill-related component of physical fitness that is crucial for a basketball player to quickly
change direction?
Antwortdetails
Physical fitness components are divided into two categories: health-related (cardiovascular endurance, muscular strength, muscular endurance, flexibility, body composition) and skill-related (agility, balance, coordination, speed, reaction time, power). The question asks specifically for a skill-related component linked to quickly changing direction.
Agility is defined as the ability to change the position and direction of the body quickly and effectively while maintaining control. In basketball, players must constantly cut, pivot, and change direction to evade defenders, drive to the basket, or stay with an opponent on defence. This makes agility the most directly relevant component.
Speed refers to how fast a person can move from one point to another in a straight line. Reaction time is the interval between a stimulus and the initiation of a response. Power is the ability to exert maximum force in the shortest time. While all of these matter in basketball, none of them specifically describes the ability to change direction rapidly, which is the defining feature of agility.
Frage 28 Bericht
In basketball, which skill is used to quickly change direction while maintaining control of the ball?
Antwortdetails
Pivoting is the basketball skill specifically designed for quickly changing direction while maintaining control of the ball. When a player pivots, one foot (the pivot foot) remains fixed on the floor while the other foot steps in any direction. This allows the player to turn their body, face a new direction, and protect the ball from a defender - all without committing a travelling violation.
The other options serve different purposes in basketball:
Pivoting is a fundamental skill that guards and forwards use extensively to create passing angles, protect possession, and evade defensive pressure.
Frage 29 Bericht
Which of the following is an example of health promotion?
Antwortdetails
Health promotion encompasses activities and strategies designed to prevent disease and enhance the overall health and well-being of a population before illness occurs. It operates at the primary prevention level, targeting entire communities to reduce the incidence of disease rather than treating individuals who are already sick.
Vaccination campaigns to prevent infectious diseases are a classic example of health promotion. Mass immunisation programmes protect individuals and create herd immunity within populations, stopping the spread of diseases such as measles, polio, and tuberculosis before they can take hold.
The other options represent different levels of healthcare, not health promotion:
The defining feature of health promotion is its proactive, preventive nature. It aims to keep healthy people healthy, rather than restoring health after it has been lost.
Frage 30 Bericht
What type of communicable disease is caused by protozoa?
Antwortdetails
Protozoa are single-celled eukaryotic organisms that can cause communicable diseases classified as parasitic infections. Well-known examples include malaria (caused by Plasmodium species, transmitted by Anopheles mosquitoes), amoebic dysentery (caused by Entamoeba histolytica), sleeping sickness (caused by Trypanosoma), and giardiasis (caused by Giardia lamblia). Because protozoa live in or on a host organism and derive nutrients at the host's expense, the diseases they cause are categorised as parasitic.
The other categories involve different types of pathogens:
Exam tip: Protozoa are parasites. Whenever a question links protozoa to a disease category, the answer is parasitic infections.
Frage 31 Bericht
Which of the following is the best way to care for dry skin?
Antwortdetails
Dry skin (also called xerosis) occurs when the skin loses moisture faster than it can replenish it, leading to tightness, flaking, roughness, and sometimes itching or cracking. The best care approach involves two complementary strategies: using gentle cleansers and moisturising regularly.
Gentle cleansers (soap-free or pH-balanced cleansers) clean the skin without stripping away its natural oils (sebum) and disrupting the skin's protective lipid barrier. Harsh soaps and detergents remove these oils aggressively, worsening dryness.
Regular moisturising replenishes the skin's hydration and creates a protective layer that slows moisture loss. Moisturisers containing ingredients such as glycerin, hyaluronic acid, or ceramides are particularly effective for dry skin.
The other options would worsen dry skin. Prolonged exposure to direct sunlight damages the skin through UV radiation, further drying it out and increasing the risk of sunburn and premature ageing. Frequent hot water baths strip natural oils from the skin far more than lukewarm water does, and harsh soaps compound this effect. Avoiding washing entirely leads to accumulation of dead skin cells, dirt, and bacteria, which does not help maintain skin hydration and creates hygiene problems.
Frage 32 Bericht
Which of the following is considered the most important component of physical fitness for overall health?
Antwortdetails
Cardiorespiratory endurance is widely regarded as the most important component of physical fitness for overall health. It refers to the ability of the heart, lungs, and blood vessels to deliver oxygen to working muscles during sustained physical activity, and the ability of those muscles to use the oxygen efficiently.
Cardiorespiratory endurance is considered the most important because:
The other components of physical fitness are important but are not considered as critical to overall health:
Frage 33 Bericht
A key difference between the Greek and Roman philosophy of physical education was that the Greeks valued balance
and the Romans valued:
Antwortdetails
The ancient Greeks and Romans both valued physical education, but their philosophies differed significantly in purpose and emphasis.
The Greeks pursued an ideal of balance between mind and body, captured in the concept of kalokagathia (beauty and goodness combined). Greek physical education aimed to develop the whole person: athletic competition, aesthetic grace, and intellectual cultivation were seen as complementary. The Olympic Games, gymnastics, and wrestling were pursued for personal excellence and harmony, not solely for practical ends.
The Romans, by contrast, valued military discipline and utility. Physical training in Rome was primarily a preparation for warfare. Roman citizens trained to become effective soldiers: marching, swimming, javelin throwing, and sword fighting were emphasised because they had direct military applications. The Roman approach was pragmatic rather than aesthetic - physical fitness served the state and its legions.
The other options do not fit the Roman philosophy. Artistic expression was a Greek emphasis. Intellectual superiority was valued in Greek academia (Plato's Academy, Aristotle's Lyceum). Individualistic pursuits are more characteristic of the Greek model of personal excellence, whereas Roman physical education served collective, state-oriented military goals.
Frage 34 Bericht
During physical activity, what is the key role of the trachea in maintaining a high level of performance?
Antwortdetails
The trachea (windpipe) is a tube approximately 10-12 cm long that connects the larynx to the bronchi, serving as the main passageway for air travelling to and from the lungs. Its walls are reinforced by C-shaped rings of hyaline cartilage that prevent the trachea from collapsing, even when external pressure changes or the neck moves.
During physical activity, the body's demand for oxygen increases dramatically, and the rate and depth of breathing rise to meet this demand. The trachea's key role in maintaining performance is that it remains a clear and open airway, allowing the rapid and unobstructed flow of air into and out of the lungs. The rigid cartilage rings ensure the airway stays patent regardless of how forcefully the person breathes.
The other options contain inaccuracies. While the respiratory tract does humidify inhaled air, this function is primarily carried out by the nasal cavity and mucous membranes higher in the airway, not the trachea's main contribution during exercise. The trachea does not contract to force air out - exhalation during exercise is driven by the diaphragm, internal intercostal muscles, and abdominal muscles. The trachea also does not significantly widen during exercise; it is the bronchioles (smaller airways within the lungs) that dilate through bronchodilation to increase airflow.
Frage 35 Bericht
The ISSF is the international governing body for which sport?
Antwortdetails
ISSF stands for the International Shooting Sport Federation. It is the global governing body responsible for regulating and promoting shooting sports worldwide. The ISSF oversees Olympic shooting events including rifle, pistol, and shotgun disciplines.
The ISSF was founded in 1907 and is headquartered in Munich, Germany. It organises World Championships, World Cups, and sets the rules for shooting events at the Olympic Games.
The other options refer to different sports governed by different international bodies:
When studying international sports organisations, pay attention to the acronyms - ISSF specifically uses the word "Shooting" and should not be confused with other federations whose names begin with similar letters.
Frage 36 Bericht
What corrective exercise principle is essential for improving mobility in stroke survivors?
Antwortdetails
For stroke survivors, the most effective corrective exercise principle for improving mobility is task-specific repetitive training. This approach is grounded in the concept of neuroplasticity - the brain's ability to reorganise itself by forming new neural connections. After a stroke damages part of the brain, repeatedly practising specific functional tasks (such as reaching for a cup, walking, or climbing stairs) stimulates the undamaged areas of the brain to take over the lost functions.
The key features of task-specific repetitive training are:
The other options are inadequate or harmful:
Frage 37 Bericht
Why do sprinters lean forward during the start?
Antwortdetails
In sprinting, the start phase is critical for generating maximum acceleration. When a sprinter leans forward from the blocks, they shift their centre of gravity ahead of their base of support. This creates a controlled forward imbalance that the body can only correct by driving the legs powerfully forward and downward against the ground.
According to Newton's Third Law, the ground exerts an equal and opposite reaction force on the sprinter. Because the body is angled forward, this reaction force has a large horizontal component, propelling the sprinter forward rather than upward. The forward lean therefore maximises the horizontal force produced with each stride during the acceleration phase.
The other options do not accurately describe the purpose of the forward lean. Looking at the finish line is irrelevant at the start. The lean actually makes balancing harder, not easier, which is precisely the point: the instability forces the body to drive forward. While a forward lean can reduce frontal area and therefore air resistance to some extent, this effect is minimal at the low speeds of the starting phase and is not the primary reason for the technique.
Frage 38 Bericht
What is the main function of the 'shin guards' worn by football players?
Antwortdetails
Shin guards are a mandatory piece of protective equipment in football (soccer). Their main function is to protect the player's lower legs from kicks and impacts. The tibia (shinbone) sits just beneath the skin on the front of the lower leg with very little natural padding of muscle or fat. During a match, players frequently receive accidental or unavoidable kicks, collisions, and stud impacts to this area, which can cause bruising, lacerations, or even fractures without protection.
Shin guards are made of hard plastic or composite materials and are worn underneath the socks, covering the front of the lower leg from just below the knee to above the ankle. The Laws of the Game (Law 4) require every player to wear shin guards as a basic piece of equipment.
The other options are incorrect. Shin guards have nothing to do with grip on the ball - that depends on boot design and technique. They do not provide ankle support - ankle braces or tape serve that purpose. They also do not improve speed or agility; if anything, they add a small amount of weight, though this is negligible.
Frage 39 Bericht
Which of the following is a key benefit of participating in NATCEGA?
Antwortdetails
NATCEGA (Nigerian Colleges of Education Games Association) organises sporting competitions among Colleges of Education in Nigeria. Its key benefits centre on the development of student-athletes and the broader promotion of sport within the educational system.
The most accurate benefit is the promotion of physical fitness and talent identification. Through NATCEGA competitions, students are encouraged to engage in regular physical activity, which improves their overall fitness and health. At the same time, the games serve as a platform where talented athletes can be discovered and developed further, potentially progressing to represent their states or Nigeria at national and international competitions.
The other options do not accurately describe NATCEGA's benefits. Scholarship opportunities for non-athletes is not a direct function of NATCEGA, which focuses specifically on sports participation. Reduced academic workload is not a benefit of participating in sports competitions; in fact, student-athletes must often balance their training with their studies. Guaranteed employment after graduation is unrelated to sports participation in NATCEGA - the games do not provide employment guarantees to participants.
Frage 40 Bericht
Why is dietary fibre an important part of a balanced diet?
Antwortdetails
Dietary fibre (also called roughage) is the indigestible portion of plant foods, primarily made up of cellulose and other complex carbohydrates that human digestive enzymes cannot break down. Its importance in a balanced diet lies in its role in regulating digestion and preventing constipation.
Fibre works by absorbing water in the large intestine, which adds bulk to the stool and makes it softer and easier to pass. This stimulates peristalsis - the wave-like muscular contractions that move food through the digestive tract - promoting regular bowel movements and reducing the risk of constipation, haemorrhoids, and diverticular disease.
The other options misattribute functions to fibre:
