1.   True (A) or false (B) – click on the correct answer:
Managing chronic diseases of lifestyle falls beyond the 
scope of practice of biokinetics. 

2.   True (A) or false (B) – click on the correct answer:
In developed countries, physical inactivity is 
associated with less than 7% of deaths. 

3.   True (A) or false (B) – click on the correct answer:
Approximately 500 new biokineticists are trained each 
year in South Africa.  

4.   True (A) or false (B) – click on the correct answer:
Less than 5% of South Africans with a monthly income 
above R2 785 utilise primary health care. 

5.   True (A) or false (B) – click on the correct answer:
There is no further capacity for using exercise as a 
modality to treat chronic diseases of lifestyle in the 
private health care sector of South Africa.

6.   True (A) or false (B) – click on the correct answer:
Although athletes with spinal cord injuries 
thermoregulate in a similar manner to able-bodied 
athletes, they tend to store slightly more heat.  

7.   True (A) or false (B) – click on the correct answer:
Three days of repeated endurance sub-maximal mountain 
biking disrupts the sleep of the mountain bikers on the 
third night of cycling.   

8.   True (A) or false (B) – click on the correct answer:
Variables such as age, gender, body mass and fitness all 
influence the relationship between exercise and sleep.

9.   True (A) or false (B) – click on the correct answer:
Actigraphy is the gold standard method for measuring 
quality of sleep.

10.   True (A) or false (B) – click on the correct answer:
Objective and subjective measures of sleep quality 
are similar, therefore it is not necessary to use both 
methods in research with quality of sleep as an outcome 
measure.

11.   True (A) or false (B) – click on the correct answer:
Because muscle glycogen is the main fuel during intense 
exercise, replenishing muscle glycogen stores in the 
post-exercise period is an important factor influencing 
recovery and performance. 

12.   True (A) or false (B) – click on the correct answer:
Muscle glycogen resynthesis is accelerated for up to  
24 hours after exercise. 

13.   True (A) or false (B) – click on the correct answer:
After a glycogen-depleting bout of exercise, glycogen 
resynthesis occurs in two phases. The first of these 
phases is dependent on the presence of insulin. 

14.   True (A) or false (B) – click on the correct answer:
A recovery meal consumed within 2 hours after 
exercise is more effective for improving recovery than 
no feeding.

15.   True (A) or false (B) – click on the correct answer:
Protein contributes an estimated 40% of total energy 
expenditure during endurance exercise.

16.   True (A) or false (B) – click on the correct answer:
Plain yoghurt is an effective, but lower-cost, recovery 
aid due to a CHO:PRO ratio which is similar to many 
commercial recovery and carbohydrate-replacement 
beverages.

17.   True (A) or false (B) – click on the correct answer:
Although research studies suggest that post-exercise 
recovery beverages containing protein seem to be 
effective in improving recovery indices, it may be argued 
that some of the results may be attributed to the higher 
caloric content of the CHO:PRO supplements. 

18.   True (A) or false (B) – click on the correct answer:
Patients with peripheral arterial disease should avoid 
exercise.

19.   True (A) or false (B) – click on the correct answer:
Patients with peripheral vascular disease and control 
patients have similar concentrations of circulating 
lactate in skeletal muscle coinciding with maximal 
exercise capacity.

20.   True (A) or false (B) – click on the correct answer:
Reporting a ‘mean’ response following an intervention 
may fail to convey the individual variation which exists 
in a group. This may result in misleading interpretation 
of the intervention.
