摘要: Forty-two subjects (34–50 years old) were studied before and after an 8–10 weeks' conditioning program. Maximal oxygen uptake increased in all subjects, mean increase from 2.89 l/min to 3.44 l/min. pulmonary ventilation by 15 per cent 128 This was brought about the respiratory rate 42 46. Heart at a given submaximal effort on bicycle ergometer 10–20 beats/min lower training, maximal heart lowered 193 186 beats/min. The blood lactate concentration training program but not when related relative work load. initial level for larger improvement training.
