[Effect of water fasting on sport performances in the laboratory].
15 sport men heart rate and central temperature were measured at rest and at the end of a progressive maximal exercise. Maximum consumption of oxygen (VO2 max) was estimated after the effort. The experience began in the morning from 9 to 11 a.m. and the afternoon from 4 to 6 p.m. In the first time subjects had a normal alimentation and in the second they observed a rigorous fast. The comparison of the results doesn't show difference induced by fast on VO2 max and maximal heart rate. However heart rate at rest and capacity of work decrease during fast and permit to think that a more intensive and long exercise in more strenuous climates than this one should give significative modifications.
