月经周期在高强度间歇训练 (HIIT) 中影响骨肌肉的氧化. 高激素阶段受益于更长的HIIT间隔,而荷尔蒙避孕药使用者在更短的间隔中表现出更大的氧化波动.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 妇女健康 妇女健康
背景情况:
- 月经周期 (MC) 期间的荷尔蒙波动可能会影响对运动的生理反应.
- 骨肌氧化率 (SMO) 是高强度间歇训练 (HIIT) 期间肌肉功能的关键指标.
- 在HIIT期间了解MC阶段对SMO的影响可以优化女性运动员的训练和恢复.
研究的目的:
- 为了研究月经周期阶段在不同HIIT协议期间对骨肌肉氧化的影响.
- 为了在MC中比较eumenorrheic (EUM) 和荷尔蒙避孕药 (HC) 用户之间的SMO反应.
- 根据MC阶段和避孕药的使用,为运动处方和恢复策略提供信息.
主要方法:
- 参与者包括EUM (n=26) 和HC用户 (n=11).
- 在MC的低激素 (LHP) 和高激素 (HHP) 阶段执行了两个HIIT协议 (HIIT1:1和HIIT2:1).
- 骨肌肉氧化 (组织和指数[TSI]和总血红蛋白[THb]) 用近红外光谱测量.
主要成果:
- 在HIIT1:1期间,与HHP相比,LHP发生了更大的TSI脱.
- 在HIIT2:1期间,与LHP相比,HHP发生了更大的TSI脱和再和.
- 荷尔蒙避孕药使用者在HIIT2:1期间在HHP和LHP中表现出更大的SMO波动.
结论:
- 月经周期在HIIT期间显著影响骨肌肉氧化.
- 高激素阶段似乎更有利于更长的HIIT间隔 (HIIT1:1).
- 荷尔蒙避孕药的使用可能会导致SMO在更短,更强烈的HIIT间隔 (HIIT2:1) 期间变化更大.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

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...
