Body composition and dietary intake of the FNB Maties Varsity 
Cup rugby players
1.  The Varsity Cup rugby forwards had an average body mass index 

(BMI) of 32.5, showing that they were all obese.           
2.  The Varsity Cup rugby players had the same body composition 

compared with national and international rugby players.        
3.  The Varsity Cup rugby players as a group had an inadequate 

intake of total energy, carbohydrate, polyunsaturated fatty acids, 
calcium:protein ratio and copper.     

4.  The Varsity Cup rugby players as a group had higher-than-
recommended values for total protein, fibre, total fat, saturated 
fatty acids, cholesterol and niacin.    

5.  The macronutrient intake of the rugby players >2 hours before the 
rugby game was adequate for energy and carbohydrate intake, 
but high in protein and fat intake.    

Effect of caffeine ingestion on fluid balance during exercise in the 
heat and during recovery
6.  Athletes have been advised to abstain from caffeine during 

exercise because of its diuretic effect. 
7.  Moderate caffeine ingestion (mean 460 mg) altered urine 

production during and after exercise. 
8.  Three to four cups of regular brewed coffee would not place 

healthy young individuals at higher risk of hypohydration.   
9. There is approximately 150 mg caffeine per 150 mL coffee.   

Associations of physical activity with trabecular and cortical bone 
properties in prepubertal children
10.  Two of the most common physical activity assessments used for 

research purposes are maximum oxygen consumption (VO2 max) 
tests and physical activity questionnaires.   

11.  In this study, peak bone strain score was significantly associated 
with spine, hip, femoral neck and ulna bone mineral content.    

12.  Dual energy X-ray absorptiometry is useful for monitoring bone 
response to exercise, because the method assesses bone geometry 
and small increments (due to loading physical activities) on the 
periosteal surface of the bone.  

13.  Pedometers may be limited in their ability to reflect time spent in 
moderate-to-vigorous physical activity as they only measure steps 
per day and have a high amount of variability when used by people 
with different gait patterns.   

14.  In this study, moderate and combined moderate-to-vigorous 
activity was significantly associated with bone mineral content at 
the femoral neck whereas vigorous activity was associated with 
bone mineral content at the hip only.    

Obesity in 7 - 10-year-old children in urban primary schools
15.  South Africa has the lowest rate of obesity in children in sub-

Saharan Africa.    
16.  The prevalence of childhood obesity in developing countries is 

associated more with children from lower socio-economic areas 
than their more economically privileged counterparts.    

Dietary supplements containing prohibited substances
17.  Dietary supplement manufacturers have to prove the efficacy of 

their products before they are sold.   
18.  Ephedrine is structurally similar to amphetamine and therefore 

has similar modes of action and a comparable side-effect profile.   
19.  The stimulant methylhexaneamine was originally intended to be 

marketed as a nasal decongestant, but has been detected as an 
ingredient of dietary supplements.  

Chronic exertional compartment syndrome in the forearm
20.  Chronic exertional compartment syndrome of the forearm is 

common and is a well-known clinical condition.
