This study investigated the effects of drink composition on voluntary intake, hydration status, selected physiological responses and affective states during simulated gymnasium-based exercise. In a randomised counterbalanced design, 12 physically active adults performed three 20-min intervals of cardiovascular exercise at 75% heart rate maximum, one 20-min period of resistance exercise and 20 min of recovery with ad libitum access to water (W), a carbohydrate-electrolyte solution (CES) or with no access to fluids (NF). Fluid intake was greater with CES than W (1706±157 vs. 1171±152 mL; P<0.01) and more adequate hydration was achieved in CES trials (NF vs. W vs. CES: -1668±73 vs. -700±99 vs. -273±78 g; P<0.01). Plasma glucose concentrations were highest with CES (CES vs. NF vs. W: 4.26±0.12 vs. 4.06±0.08 vs. 3.97±0.10 mmol/L; P<0.05). Pleasure ratings were better maintained with ad libitum intake of CES (CES vs. NF vs. W: 2.72±0.23 vs. 1.09±0.20 vs. 1.74±0.33; P<0.01). Under conditions of voluntary drinking, CES resulted in more adequate hydration and a better maintenance of affective states than W or NF during gymnasium-based exercise.
本研究旨在探讨饮料成分对模拟体育馆运动中自愿摄入、水合状态、选择的生理反应和情绪状态的影响。在一项随机交叉设计中，12 名活跃的成年人在 75%最大心率的心血管运动中进行了三次 20 分钟的间隔，一次 20 分钟的阻力运动和 20 分钟的恢复，自由摄入水 (W)、碳水化合物-电解质溶液 (CES) 或不摄入液体 (NF)。CES 的液体摄入量大于 W (1706±157 比 1171±152 mL；P<0.01)，并且 CES 试验中实现了更充足的水合 (NF 比 W 比 CES：-1668±73 比-700±99 比-273±78 g；P<0.01)。CES 的血浆葡萄糖浓度最高 (CES 比 NF 比 W：4.26±0.12 比 4.06±0.08 比 3.97±0.10 mmol/L；P<0.05)。CES 的愉悦评分保持得更好 (CES 比 NF 比 W：2.72±0.23 比 1.09±0.20 比 1.74±0.33；P<0.01)。在自愿摄入的情况下，CES 导致在体育馆运动期间比 W 或 NF 更充足的水合和更好的情绪状态维持。
