| 摘 要： | 通过测量呼吸商,研究了补充肌酸对于安静时机体底物利用的影响.10名男子,进行12周的力量训练,分两个阶段进行肌酸补充.在第12周以后测量体重、呼吸商和力量大小.在实验组和对照组,股四头肌力量显著增加,体重在补肌酸组增加,但在对照组没有增加;在补充肌酸组,呼吸商增大,表明糖在供能底物中的氧化率增加. |

| Abstract: | The influence of creatine supplementation on substrate utilization during rest was investigated. Ten active males participated in 12-week weight training and were given creatine and placebo (20g/day for 4days, then 2g/day for 17days) in two trials separated by a 4-week time. Substrate utilization and strength were assessed after the second trial. 1-RM strength was increased only after creatine. Total body mass increased after creatine but not after placebo. Carbohydrate oxidation was increased by creatine, whereas there was a trend for increased respiratory exchange ratio after creatine supplementation. Changes in substrate oxidation may influence the inhibition of fat mass loss associated with creatine after weight training. |
