概括
在上坡试验后的验证阶段对于确定真正的最大氧气吸收 (VO2max) 具有很小的价值. 低峰测试可能会增加极少的洞察力,而高峰测试则不会提供任何额外的好处.
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
- 心血管健康 呼吸系统健康
背景情况:
- 精确确定最大氧气摄入量 (VO2max) 对于评估有氧健身至关重要.
- 露台测试通常用于估计VO2max,但验证阶段有时用于确认真正的最大值.
- 悬崖后测试验证阶段的附加价值仍在争论中.
研究的目的:
- 为了检查在机场测试后的次峰 (95%) 或超峰 (105%) 验证阶段是否提高了"真实"最大氧气吸收 (VO2max) 的确定.
主要方法:
- 训练有素的雄性和雌性完成了两次登陆式试验,然后在95%或105%的峰值功率输出时进行验证阶段.
- 在测试之间的恢复允许血乳酸恢复到≤4 mmol·L−1.1.
- 验证阶段的值是根据VO2峰值相对于露台测试的VO2峰值进行分类的:没有值 (<97%),潜在值 (97-103%),或确定的值 (>103%).
主要成果:
- 在95%的验证阶段,20项测试显示没有附加值,11项显示潜在价值.
- 在105%验证阶段,26项测试显示没有附加值,5项显示潜在价值.
- 在任何一个验证阶段的测试都没有证明"确定的价值".
结论:
- 在上坡测试后进行次峰值验证阶段,为准确确定训练有素的成年人VO2max提供了最小的附加值.
- 一个超峰值验证阶段为确定"真正的"最大氧气吸收提供了没有额外的价值.

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
