Summary
A group of 9 Vietnamese physicians (V.) is compared with 9 Czechoslovakian physians (C.) of the same age. The V. group have average height of 162±2 cm and weight of 52±1.7 kg, a lower maximum Vo2/min. of 1827±314 which is not significant when expressed per 1 kg body weight, (33±5 ml). The respective values for C. are 175±2.2 cm, 77±2 kg, 3069±279 ml and 40±1.8 ml. Further there are statistically significant differences between both groups in ventilation, heart rate and RQ, during various degrees of work-load, but not in O2 consumption and efficiency of work at a work-load of 400–800 kg-m/min. The maximum aerobic capacity in the V. group is lower as compared with the C. group and a lower work capacity results from this. The causes of this difference are discussed.
