The efficacy of the use of an upper body compression garment (UBCG) as an ergogenic aid to reduce thermoregulatory strain in older adults remains unknown. The aim of this study was to evaluate the effects of UBCG on thermoregulatory, cardiorespiratory, and perceptual responses during cycling in a temperate environment (~25 °C, 66% rh) in trained older adults. Twelve cyclists aged 66 ± 2 years performed an intermittent 1-hr cycling trial at 50% of the peak power output followed by 10 min of passive recovery. Participants were provided with either commercially available UBCG or a control garment in a randomized order. UBCG increased thermoregulatory strain during exercise, as indicated by a significantly higher core temperature (38.1 ± 0.3 °C vs. 37.9 ± 0.3 °C; p = .04), body temperature (36.9 ± 0.2 °C vs. 36.7 ± 0.2 °C; p = .01), and thermal sensation (8.0 ± 0.4 vs. 7.5 ± 1.0; p = .02). These results suggest that the use of UBCG in trained older adults does not reduce the thermoregulatory strain during moderate exercise.
使用上身压缩服装(UBCG)作为一种提高运动能力的辅助手段来减轻老年人的体温调节压力,其效果尚不清楚。本研究的目的是评估在温带环境(约25°C,相对湿度66%)中,训练有素的老年人骑行时UBCG对体温调节、心肺和感知反应的影响。12名年龄在66±2岁的自行车骑行者以峰值功率输出的50%进行了1小时的间歇性骑行试验,随后进行10分钟的被动恢复。参与者被随机提供市售的UBCG或对照服装。UBCG在运动期间增加了体温调节压力,表现为核心温度显著更高(38.1±0.3°C对37.9±0.3°C;p = 0.04)、体温(36.9±0.2°C对36.7±0.2°C;p = 0.01)和热感觉(8.0±0.4对7.5±1.0;p = 0.02)。这些结果表明,在训练有素的老年人中使用UBCG并不能减轻中等强度运动期间的体温调节压力。
