OBJECTIVES
The purpose of this study was to evaluate the cardiorespiratory response and energy expenditure during the practice of Tai Chi Easy (TCE). TCE has been proposed as a low-intensity alternative to traditional physical activity.
DESIGN
Oxygen cost data were collected from 10 healthy adult women (mean age of 47.9 ± 12.8 years) at rest and during a 30-min session of TCE using an automated metabolic cart and heart rate (HR) telemetry. The Borg rating of perceived exertion (RPE) scale was utilized to measure subjective intensity of the TCE movements.
RESULTS
The mean oxygen consumption (VO(2)) for the movements ranged from 4.3 ml kg(-1)min(-1) to 5.5 ml kg(-1)min(-1) with an overall mean of 5.0 ml kg(-1)min(-1). The mean HR for all activity was 67.0 beats per minute and the mean energy expenditure (EE) was 1.6 Kcal min(-1).
CONCLUSIONS
Cardiorespiratory and EE responses to TCE indicate that this a low intensity exercise appropriate for individuals requiring activity prescriptions of approximately 2 metabolic equivalents (METs).
目的
本研究旨在评估简易太极拳（TCE）练习过程中的心肺反应和能量消耗。TCE已被提议作为传统体育活动的低强度替代方式。
设计
使用自动代谢分析仪和心率遥测技术，收集了10名健康成年女性（平均年龄47.9±12.8岁）在静息状态以及30分钟TCE练习过程中的氧耗数据。采用Borg自觉用力程度（RPE）量表来测量TCE动作的主观强度。
结果
动作的平均耗氧量（VO₂）范围为4.3毫升·千克⁻¹·分钟⁻¹至5.5毫升·千克⁻¹·分钟⁻¹，总体平均值为5.0毫升·千克⁻¹·分钟⁻¹。所有活动的平均心率为每分钟67.0次，平均能量消耗（EE）为1.6千卡·分钟⁻¹。
结论
对TCE的心肺和EE反应表明，这是一种低强度运动，适合需要约2代谢当量（METs）活动处方的个体。
