Anthropometric study of medical students
(Sri Lanka Medical Association. Colombo, 1988) Balasuriya, P.
Stature, sitting height, biacromial diameter, total arm length and foot length were measured in 133 mdical students. Analysis of data showed no ethnic differences in the mean values for measurements in males and females, in contrast to some past studies. Sex differences in the mean values were significant. Stature, sitting height, total arm length showed positive correlation with each pther in both sexes. While the correlation of biocromial diameter with other measurements was low in males, there was no correlation in females. The results indicate that a significant increase in stature since 1937 and 1948 has taken place due to a disproportionate increase in length of the lower limbs compared to the trunk. The upper limbs too appear to show an increase in length proportionate to stature. There is a significant increase in the transverse diameter of the upper end of the trunk. Certain segments of the body bear a constant relation ship to stature in both sexes.

Physical fitness in Sri Lankan students
(The Sri Lanka Medical Association. Colombo, 1992) Balasuriya, P.
Meaximum oxygen uptake (VO2 max) was determined in agroup of sendentary medical students of both genders and ina group of University students and school children engaged in regular sports practices. The subjects were selected on a voluntary basis. The steady state heart rate during submaximal exercise on a bicycle ergometer was used to predict the VO2 max from the Astrand nomogram. The fitness index calculated aas VO2 max in ml/kg body weight was to determine the fitness level adjusted for age from the Astrand table. The male sendentory and sports groups had fitness indices which corresponded to 'poor' and 'average' fitness levels, respectively. The female sedentary and sports groups had fitness indices which were not significantly different from those of the corresponding male groups and which corresponded to 'average' and 'good' fitness levels, respectively. Weight-lifters had a fitness level similar to that of the male sendentary group.\
