Abstract
Strenuous athletic training for 6 mos. did not affect the basal HbO2 capacity, plasma protein, blood lactic acid, blood sugar, alkaline reserve or alveolar CO2 tension in 9 [male][male]. The ability of [male][male] to accumulate lactic acid during anaerobic work increased with training; during the same work there were corresponding declines in alkaline reserve and alveolar CO2 tension. The changes in blood sugar and HbO2 capacity caused by the work remained about the same throughout training. During grade walking blood sugar and lactic acid declined slightly with training and alveolar CO2 tension remained unchanged and at about the same level as the basal values. In submaximal running the blood lactate and sugar declined significantly with training.
