1Which energy system is the predominant ATP supplier during a maximal effort lasting about 8 seconds, such as a short sprint or a single heavy lift?

A.Oxidative (aerobic) system

B.ATP-PCr (phosphagen) system

C.Fast glycolytic (anaerobic glycolysis) system

D.Fatty-acid beta-oxidation

Explanation: Very short, maximal efforts of roughly 0-10 seconds rely chiefly on stored ATP and phosphocreatine (the ATP-PCr or phosphagen system), which regenerates ATP rapidly without oxygen but is depleted quickly.

2VO2max is best defined as the:

A.Maximal heart rate achievable during a graded exercise test

B.Maximum rate at which the body can take up and utilise oxygen during exhaustive exercise

C.Resting metabolic rate expressed per kilogram of body mass

D.Oxygen cost of breathing at maximal ventilation

Explanation: VO2max is the highest rate of oxygen uptake and utilisation the body can achieve during maximal exercise, integrating cardiac output and arterio-venous oxygen difference. It is the gold-standard measure of cardiorespiratory fitness.

3According to the Fick equation, VO2 is the product of cardiac output and the:

A.Arterio-venous oxygen difference (a-vO2 diff)

B.Mean arterial pressure

C.Respiratory exchange ratio

D.Pulmonary diffusion capacity

Explanation: The Fick principle states VO2 = cardiac output x (a-vO2 difference). Cardiac output (heart rate x stroke volume) delivers oxygenated blood, and the a-vO2 difference reflects how much oxygen the tissues extract.

4During progressive dynamic aerobic exercise in a healthy adult, which cardiovascular response is expected?

A.Systolic blood pressure rises while diastolic pressure stays similar or falls slightly

B.Both systolic and diastolic pressure fall progressively

C.Diastolic pressure rises by more than 20 mmHg as a normal response

D.Stroke volume falls steadily from the onset of exercise

Explanation: With increasing dynamic aerobic workload, systolic blood pressure rises in proportion to intensity because of increased cardiac output, while diastolic pressure changes little or decreases slightly due to vasodilation in working muscle.

5The ventilatory (anaerobic) threshold during incremental exercise is characterised by:

A.A plateau in heart rate despite increasing workload

B.A disproportionate rise in ventilation relative to oxygen uptake as lactate accumulates

C.A fall in carbon dioxide production

D.A reduction in tidal volume at high intensity

Explanation: At the ventilatory threshold, accumulating blood lactate is buffered by bicarbonate, generating extra CO2 and driving ventilation up disproportionately to VO2. This non-linear rise in ventilation marks the threshold.

6One metabolic equivalent (1 MET) corresponds to an oxygen consumption of approximately:

A.1.5 mL O2 per kg per minute

B.3.5 mL O2 per kg per minute

C.7.0 mL O2 per kg per minute

D.10.5 mL O2 per kg per minute

Explanation: By convention 1 MET equals resting oxygen consumption, about 3.5 mL of oxygen per kilogram of body mass per minute. METs let clinicians express the energy cost of activities as multiples of rest.

7Slow-twitch (Type I) muscle fibres are best characterised as:

A.High glycolytic capacity, rapid fatigue, low mitochondrial density

B.High oxidative capacity, fatigue resistant, rich in mitochondria and capillaries

C.The primary fibres recruited for a one-repetition-maximum lift

D.Devoid of myoglobin and appearing pale

Explanation: Type I fibres have high mitochondrial and capillary density, high myoglobin content and oxidative enzyme activity, making them fatigue resistant and ideal for sustained endurance activity.

8Excess post-exercise oxygen consumption (EPOC) refers to:

A.The oxygen deficit incurred at the start of exercise

B.Elevated oxygen uptake above resting levels during recovery after exercise

C.The drop in oxygen uptake during steady-state exercise

D.Oxygen used solely for replenishing muscle glycogen

Explanation: EPOC is the sustained elevation of oxygen consumption above baseline during recovery, reflecting restoration of ATP-PCr stores, lactate clearance, replenishment of oxygen stores, and raised body temperature and catecholamines.

9Which adaptation is a classic chronic response to prolonged aerobic endurance training?

A.Decreased capillary density in trained muscle

B.Increased mitochondrial density and increased maximal stroke volume

C.Reduced VO2max

D.Increased resting heart rate

Explanation: Endurance training increases mitochondrial number and size, capillary density, blood volume and left-ventricular filling, raising maximal stroke volume and VO2max while lowering resting and submaximal heart rate.

10At rest and low exercise intensities, the predominant fuel source is:

A.Free fatty acids (fat oxidation)

B.Muscle phosphocreatine

C.Blood lactate

D.Branched-chain amino acids

Explanation: At rest and during low-intensity steady-state activity, fat oxidation supplies most of the energy because there is ample oxygen and the demand is low. As intensity rises, the body shifts progressively toward carbohydrate.

About the HPCSA Biokinetics Exam Exam

The HPCSA Biokinetics National Board Examination assesses whether candidates are competent to register and practise as biokineticists in South Africa. Biokinetics is a final-phase functional rehabilitation profession that improves physical and physiological health through individualised evaluation and exercise prescription for chronic clinical and orthopaedic conditions, performance and health promotion. The exam spans exercise physiology, functional anatomy and biomechanics, exercise testing and prescription, clinical exercise for chronic disease, orthopaedic rehabilitation, special populations, screening, test safety and professional ethics within the HPCSA scope.

HPCSA Biokinetics Exam: Suggested Study Strategy

1Build a strong foundation in exercise physiology and functional anatomy first, because energy systems, VO2max, the Fick equation, muscle actions and biomechanics underpin the testing, prescription and rehabilitation questions.

2Memorise the safety essentials cold: absolute and relative contraindications to exercise testing, test-termination criteria, and basic life support including CPR and AED use, since wrong clinical decisions here are heavily penalised and patient-critical.

3Practise applying screening and prescription frameworks to scenarios: use pre-participation screening, cardiovascular risk factors, the FITT principle and Karvonen and RPE intensity methods on realistic clinical cases rather than memorising isolated facts, and always practise within the HPCSA scope.

Frequently Asked Questions

Who regulates biokineticists and the biokinetics board examination in South Africa?

Biokineticists are registered and regulated by the Health Professions Council of South Africa (HPCSA), specifically the Professional Board for Physiotherapy, Podiatry and Biokinetics, which sets the scope of practice, registration requirements and the National Board Examination standard.

What does the HPCSA Biokinetics board exam cover?

It assesses applied knowledge across the biokinetics scope: exercise physiology, functional anatomy and biomechanics, exercise testing and prescription, clinical exercise for chronic disease, orthopaedic rehabilitation, special populations, health screening and risk stratification, exercise test safety and emergency management, and professional ethics and scope of practice.

What is the passing score for the biokinetics board examination?

The HPCSA Professional Board sets and confirms the pass standard, and a single fixed public pass percentage is not widely published. Always rely on your official examination instructions, and in practice aim to score consistently above 70%.

Is biokinetics within the scope of diagnosing and prescribing medication?

No. Biokinetics is a final-phase exercise-therapy and health-promotion profession. Biokineticists evaluate movement and prescribe individualised exercise, but diagnosing medical conditions, prescribing medication and performing surgery fall outside their scope and require referral to the appropriate professional.
