Nowadays, Tai chi chuan (TCC) is practiced by millions worldwide with a range of skill levels. However, the effect of skill level on physiological response to TCC performance has yet to be clarified. In this study, physiological parameters during practicing simplified 24-form TCC were investigated and compared in 10 young high-level (HL) male TCC athletes and 10 ordinary-level (OL) male TCC practitioners with similar age and body size. Significantly higher energy expenditure, heart rate, oxygen uptake and tidal volume were found in HL group than OL group during TCC performance. The respiratory frequency and exhalation time were similar between the two groups during practicing TC; however, significantly less inhalation time was found in HL group (1.02±0.2 s) than OL group (1.12±0.28 s). Our results suggested that skill level may have considerable impact on metabolic and cardiorespiratory responses to TCC performance. TCC practitioners with different skill levels may practice TCC in different ways, which was supposed to lead to distinguishable response between the two groups.
如今，太极拳（TCC）在全球范围内有数百万练习者，其技能水平也各不相同。然而，技能水平对 TCC 表现的生理反应的影响尚未得到明确。在这项研究中，对 10 名年轻高水平（HL）男性 TCC 运动员和 10 名年龄和体型相似的普通水平（OL）男性 TCC 练习者进行了简化 24 式 TCC 练习期间的生理参数调查和比较。在 TCC 表现期间，HL 组的能量消耗、心率、摄氧量和潮气量明显高于 OL 组。两组在练习 TC 时的呼吸频率和呼气时间相似；然而，HL 组的吸气时间（1.02±0.2 s）明显短于 OL 组（1.12±0.28 s）。我们的结果表明，技能水平可能对 TCC 表现的代谢和心肺反应产生相当大的影响。不同技能水平的 TCC 练习者可能以不同的方式练习 TCC，这可能导致两组之间的反应不同。
