本研究的目的是比较老年气功参与者、太极拳练习者和正常久坐对照组在自行车测功术中对运动的心肺反应。36名平均年龄为59.1+/-6.6岁的社区男性参与了这项研究。每组(气功、TCC和对照组)包括12名年龄和体型匹配的受试者。气功组习练气功2.3+/-1.5年，TCC组习练杨氏气功4.7+/-2.3年。在练习气功和TCC时测量心率(HR)反应。此外，在腿部自行车的递增训练期间，还进行了心肺功能的逐次测量。气功和TCC练习时的平均心率分别为91+/-5次/分和1297次/分。在运动高峰和呼吸阈值(VET)时，TCC组的氧耗量(VO2)、氧脉搏和作业率最高。气功组的摄氧量和氧脉搏也高于对照组。在相同的相对运动强度下，气功组潮气量最大。综上所述，气功和TCC对老年人的有氧能力有一定的促进作用，但由于TCC的运动强度较高，其训练效果优于气功。然而，由于横隔膜呼吸的训练效果，气功可以在运动中提高呼吸效率。
The objective of this study was to compare cardiorespiratory responses to exercise among older Qigong participants, Tai Chi Chuan (TCC) practitioners and normal sedentary controls during cycle ergometry. Thirty-six community-dwelling men with a mean age of 59.1 +/- 6.6 years participated in this study. Each group (Qigong, TCC and control) included 12 subjects with matched age and body size. The Qigong group practiced Qigong regularly for 2.3 +/- 1.5 years; the TCC group practiced Yang TCC for 4.7 +/- 2.3 years. Heart rate (HR) responses were measured during the practice of Qigong and TCC. Additionally, breath-by-breath measurement of cardiorespiratory function was performed during the incremental exercise of leg cycling. The mean HR during Qigong and TCC practice was 91 +/- 5 bpm and 129 7 bpm, respectively. At the peak exercise and the ventilatory threshold (VeT), TCC group displayed highest oxygen uptake (VO2), O-2 pulse and work rate among the three groups. The Qigong group also showed higher oxygen uptake and O-2 pulse than the control group. At the same relative exercise intensity, the Qigong group had the highest tidal volume among the three groups. In conclusion, Qigong and TCC show a beneficial effect to aerobic capacity in older individuals, but TCC displays a better training effect than Qigong due to its higher exercise intensity. However, Qigong can enhance breathing efficiency during exercise due to the training effect of diaphragmatic breathing.
