Effect of maximal exercise on energy metabolism / 中国组织工程研究

ABSTRACT

Objective The purpose of this study was to investigate the relationship between oxygen consumption (VO2) after recovery from incremental maximal exercise and the levels of the blood lactate (HLa), glucose and alanine metabolism. Method The VO2, HLa and plasma alanine were obtained using a modified version of Bruce' s protocol 30 min after exhaustion for 10 men. Result The VO2 after recovery has returned to the pre - exercise, but the HLa concentrations and plasma alanine were significantly increased from rest to maximal exercise, and were significantly decreased thereafter, but remained above resting values for 30 min after maximal stage. Conclusion we conclude that oxygen consumption after exhaustive maximal exercise is related to glucose resyntbesis through alanine metabolism, as compared with that from lactate metabolism.
