Cardio-Respiratory Physical Training in Water and on Land,
Abstract
Fifteen unconditioned young men, who were similar in maximal aerobic power (VO2 max), were divided into three groups (n = 5 each) and physically trained for one month on a bicycle ergometer either on land (I) on immersed to the neck in water of either 32 C (II) or 20 C (III) to determine how physical training (PT) in water differs from training in air. PT considered of one-hour daily exercise bouts, 5 times/wk, with exercise intensity readjusted each week to maintain a constant training stimulus of approx. 75% VO2 max (determined on land). Throughout the training period, heart rates (HR) of III averaged 20 and 10 beats/min less thn I and II, respectively, despite working at the same VO2 an % VO2 max. Following PT, plasma volume was not increased over the pretraining values (p > 0.05) in any group. Hemoglobin concentration and hematocrit significantly increased in all three groups. Training elicited a 16% increase in VO2 max in I compared to increases of 13 and 15% for II and III, respectively. It was conducted that PT in water produces similar physiological adaptations as does training on land. In cold water, VO2 max is improved despite training with HR's significantly lower than those on land. (Author)
