Abstract

CONTEXT

The purpose of this study was to measure the oxygen consumption (V̇O) during Viniyoga yoga movements (asanas) and to compare V̇O walking among adults.

METHODS

Yoga practitioners ( = 10) were recruited to measure V̇O while at rest (30 min), practicing yoga (16 movements with different variations), and treadmill walking at 2 mph (10 min) and 3 mph (10 min). V̇O was measured using a whole-room indirect calorimetry. Each yoga movement was categorized by body orientation as standing, lying, and sitting. The differences in V̇O between yoga and walking were examined using Pearson's correlations. Differences in V̇O between poses (standing, sitting, and lying) were examined using linear regression models. V̇O.

RESULTS

Mean yoga-V̇O for the entire yoga session was 3.7 (standard deviation [SD] 0.43, range: 4.4-8.9) ml/kg/min. Yoga-V̇O varied by body orientation: standing = 7.5 (SD = 1.5) ml/kg/min, lying = 5.3 (SD = 1.0) ml/kg/min, and sitting = 5.4 (SD = 1.1) ml/kg/min. After adjusting for body mass, frequency of yoga practice, and resting energy expenditure, female gender was negatively associated with mean yoga V̇O for standing (B = -112.19, < 0.05), lying (B = -141.87, < 0.05), and sitting (B = -129.96, < 0.05). Mean V̇O for walking 2 mph was comparable with sitting ( = 0.836, < 0.05) and lying ( = 0.735, < 0.05) whereas walking at 3 mph was comparable with standing ( = 0.718, < 0.05) and sitting ( = 0.760, < 0.05).

CONCLUSION

We conclude that V̇O during yoga practice is comparable to V̇O during slow treadmill walking and may vary based on gender and body orientation.

摘要

背景

本研究的目的是测量维尼瑜伽运动（体式）期间的耗氧量（V̇O），并比较成年人的步行耗氧量。

方法

招募瑜伽练习者（n = 10），测量他们在休息（30分钟）、进行瑜伽练习（16种不同变体动作）、以2英里/小时的速度在跑步机上行走（10分钟）以及以3英里/小时的速度在跑步机上行走（10分钟）时的V̇O。使用全室间接量热法测量V̇O。每个瑜伽动作根据身体姿势分为站立、躺卧和坐姿。使用Pearson相关性检验瑜伽与步行之间V̇O的差异。使用线性回归模型检验姿势（站立、坐姿和躺卧）之间V̇O的差异。V̇O。

结果

整个瑜伽课程的平均瑜伽-V̇O为3.7（标准差[SD] 0.43，范围：4.4 - 8.9）毫升/千克/分钟。瑜伽-V̇O因身体姿势而异：站立时为7.5（SD = 1.5）毫升/千克/分钟，躺卧时为5.3（SD = 1.0）毫升/千克/分钟，坐姿时为5.4（SD = 1.1）毫升/千克/分钟。在调整体重、瑜伽练习频率和静息能量消耗后，女性与站立（B = -112.19，P < 0.05）、躺卧（B = -141.87，P < 0.05）和坐姿（B = -129.96，P < 0.05）的平均瑜伽V̇O呈负相关。以2英里/小时的速度行走时的平均V̇O与坐姿（r = 0.836，P < 0.05）和躺卧（r = 0.735，P < 0.0）相当，而以3英里/小时的速度行走时与站立（r = 0.718，P < 0.05）和坐姿（r = 0.760，P < 0.05）相当。
