智能手表估计的最大氧气摄入量 (V ̇O2max) 对中度训练的运动员是有效的,但对高度训练的个人来说不那么准确. 在精英运动员中,对于精确的V̇O2max测量,优先进行实验室分析.
科学领域:
- 运动科学 运动科学 运动科学
- 运动生理学 运动生理学
- 可穿戴技术可穿戴技术
背景情况:
- 评估最大的氧气吸收 (V·O2max) 对于评估耐力表现至关重要.
- 商用智能手表提供方便的VO2max估计,但它们在训练有素的运动员中的准确性需要验证.
研究的目的:
- 为了评估来自Garmin Forerunner 245智能手表的V̇O2max估计值与基于实验室的标准措施的有效性.
- 为了比较中度和高度训练有素的耐力运动员之间的智能手表准确性.
主要方法:
- 35名耐力运动员通过呼吸气体分析进行了标准跑步机V̇O2max测试.
- 智能手表V̇O2max估计是在两个最大值以下的户外运行过程中收集的.
- 运动员根据他们的标准V̇O2max被分为中度训练和高度训练的子组.
主要成果:
- 智能手表在所有运动员中普遍低估了V̇O2max (平均差异: -4.05到 -4.73毫升·分钟-1·公斤-1).
- 在智能手表和实验室V̇O2max值之间观察到中等一致性 (ICC:0.71-0.75),平均绝对百分比误差为7.2-7.9%.
- 适度训练的运动员 (MAPE: 2.8-4.1%) 的准确性高于高度训练的运动员 (MAPE: 9.4-10.4%),他们表现出较低的一致性 (ICC: 0.34-0.41).
结论:
- 智能手表V̇O2max的估计表明适度训练的运动员的有效性.
- 智能手表V̇O2max估计的有效性在训练有素的运动员中降低.
- 虽然智能手表V̇O2max数据对于一般监测很有用,但在精英人群中需要谨慎解释,实验室分析仍然是精确度的黄金标准.

Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.

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.
