Maximal working capacity of two professional groups in North Sumatra (Indonesia).
Two groups of male students from the medical school and sports academy and two groups of tricycle drivers performed maximally on two occasions on a brake type ergometer against a load sustainable between 2-6 min according to Tornvall. In the students the difference in work performance between the medical and sports academy students, maybe due to difference in their training condition, shown by the increment and decrement of pulse rate respectively on starting and stopping the test, since all their anthropometric measurements are the same. A comparison of the maximum working capacity between the tricycle drivers to study the effect of a potion called "jamu" showed no difference (N1 = 11, X1 = 1523 m . kp . min-1, N2 = 10, X2 = 1,664 m . kp . min-1, p greater than 0.05). The maximum working capacity of the tricycle drivers was found to be the same as the students from the sports academy (N1 = 21, X1 = 1,587 m. kp. min-1, N2 = 9, X2 = 1,524 m . kp . min-1, p greater than 0.05). Maximal heart rate between the medical students and the sports academy students differ significantly (N1 = 22, X1 = 186 min-1, N2 = 9, X2 = 175 min-1, p less than 0.01), but not significantly different between the sports academy students and the beca drivers (N1 = 9, X1 = 175 min-1, N2 = 21, X2 = 180 min-1, p greater than 0.05).
