口服避孕药阶段影响运动表现. 碳水化合物补充对于保持表现和改善恢复至关重要,无论口服避孕药周期阶段如何.
科学领域:
- 运动生理学 运动生理学
- 营养科学 营养科学
- 内分泌学 在内分泌学.
背景情况:
- 口服避孕药 (OCs) 被女性运动员广泛使用.
- 了解不同OC阶段对运动生理学的影响,对于优化训练和表现至关重要.
- 碳水化合物 (CHO) 的可用性是耐力运动能力的关键决定因素.
研究的目的:
- 调查口服避孕药 (OC) 阶段对长期,强度运动期间的表现,生理反应和主观幸福感的影响.
- 确定减少碳水化合物 (CHO) 储存对不同OC阶段炼结果的影响.
- 评估CHO补充剂在不同OC周期阶段的疗效.
主要方法:
- 十名训练有素的女自行车手完成了四次相同的150分钟的运动试验.
- 试验包括两次400kcal时间试验 (TT) 与1小时的休息时间,在试验中CHO补充剂 (CHO+) 或安慰剂 (CHO-) 的条件下.
- 这些条件在他们的单相OC周期的糖 (SUG) 和活性药丸 (ACT) 阶段均适用.
主要成果:
- 与安慰剂 (CHO-) 相比,碳水化合物补充剂 (CHO+) 将时间试验之间的表现下降降到最低.
- OC阶段和CHO可用性之间的相互作用影响了TT性能,平均输出功率,心率和情绪平衡.
- 在活性药丸 (ACT) 阶段,与CHO相比,CHO+提高了表现和运动后的情绪健康.
结论:
- 在口服避孕药的活性药片 (ACT) 阶段的碳水化合物耗尽会对时间试验的表现和情感福祉产生负面影响.
- 建议优先补充碳水化合物以维持表现和增强恢复,无论口服避孕药的阶段如何.
- 这些发现强调了针对女性运动员使用口服避孕药的荷尔蒙波动量身定制的营养策略的重要性.

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...

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...
