Abstract

We hypothesize that the V˙O2 time constant (τV˙O2) determines exercise tolerance by defining the power output associated with a "critical threshold" of intramuscular metabolite accumulation (e.g., inorganic phosphate), above which muscle fatigue and work inefficiency are apparent. Thereafter, the V˙O2 "slow component" and its consequences (increased pulmonary, circulatory, and neuromuscular demands) determine performance limits.

连接V˙O2动力学和运动耐量的生物能量机制。
我们假设V*O2时间常数(τV*O2)通过定义与肌内代谢产物积累(如无机磷酸盐)的“临界阈值”相关的功率输出来确定运动耐受性,超过该阈值,肌肉疲劳和工作效率低下是明显的。此后,V*O2“缓慢成分”及其后果(增加的肺、循环和神经肌肉需求)决定了性能极限。

期刊介绍: Exercise and Sport Sciences Reviews made the transition from an annual hardcover series book to a quarterly journal in January 2000. The mission of this American College of Sports Medicine publication is to provide premier quarterly reviews of the most contemporary scientific, medical, and research-based topics emerging in the field of sports medicine and exercise science. The publication strives to provide the most relevant, topical information to students, professors, clinicians, scientists, and professionals for practical and research applications.
