概括

训练时间显著影响耐力适应. 在小鼠中,早期阶段的训练与后期阶段的训练相比,尽管工作负载较低,但产生了更好的性能增长和更高的训练效率.

科学领域:

运动生理学运动生理学
时间生物学时间生物学
代谢适应代谢适应

背景情况:

耐力表现显示了人类和动物的日间时间变化.
运动时间对训练适应的影响尚不清楚.

研究的目的:

研究耐力训练的时间如何影响雌性小鼠的性能适应.
为了确定在早期活跃阶段 (ZT13) 或晚期活跃阶段 (ZT22) 的训练是否会导致不同的生理反应.

主要方法:

雌性小鼠在ZT13或ZT22训练了6周,每周5天,训练时间为6周.
跑步机在最大容量的70%上运行.
评估耐力表现,血糖,乳酸,身体成分,以及肌肉/肝脏糖原.

主要成果:

在ZT22测试的小鼠中,基线耐力能力更高.
与ZT22训练小鼠 (45%) 相比,ZT13训练小鼠的改善率 (132%) 更高.
两组都减少了脂肪质量;ZT13训练更有效地增强了骨肌肉适应 (例如,COXIV,酸盐合成酶活性).

结论:

运动时间是影响耐力适应的生物学相关因素.

Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
