摘要

高強度運動造成肌肉損傷進而提高肌肉的耗氧量，而礦物質是細胞能量代謝很重要的物質，本研究目的為探討補充海洋性礦物質對肌肉組織耗氧量的影響。本研究方法採交叉實驗設計，徵召甲組羽球運動員10名，在單次高強度運動前後，測量體重來判定選手的脫水量，並在高強度運動挑戰後按照脫水量的1.5倍給予飲料補充。飲料分成海洋性礦物質飲料及安慰劑兩種，而在安靜期與補充海洋性礦物質飲料後2小時使用近紅外光譜儀檢測肌肉組織氧含量及耗氧量。本實驗結果發現高強度運動降低肌肉組織血液量（93.82 ± 5.06μM > 80.35 ± 3.71μM）及提高耗氧量（0.53 ± 0.12 mVO2 ml/min/100 g muscle < 0.79 ± 0.12 mVO2 ml/min/100 g muscle），補充海洋性礦物可以降低高強度運動後2小時肌肉組織的耗氧量（0.79 ± 0.12 mVO2 ml/min/100 g muscle > 0.44 ± 0.09 mVO2 ml/min/100 g muscle）。本研究結論為運動員在高強度運動挑戰後，補充海洋性礦物質飲料可抑制高強度運動所造成的肌肉耗氧量增加的現象。

High intensity exercise-induced muscle damage leads to increase oxygen consumption in human. The purpose of this study was to investigate the effect of deep-ocean water minerals supplementation on muscle oxygen consumption after a high intensity badminton training session. Ten professional badminton players were recruited for this study, and considered as placebo and deep-ocean water trials. After performing a bout of high intensity training, all subjects were asked to drink either pure or deep-ocean water. Water intake quantity was 1.5 times higher to subjects' dehydration. Muscle oxygenation and oxygen consumption were measured by nearinfrared spectroscopy (NIRS) before and 2-h after training. We found muscle blood volume (80.35 ± 3.71 μM) was significantly decreased, while muscle oxygen consumption (0.79 ± 0.12 mVO2 ml/min/100 g muscle) was significantly increased after training in both trials. However, deep-ocean water received trial showed lower muscle oxygen consumption 2-h after exercise compared to placebo trial. In conclusion, we suggest that deep-ocean water supplementation could suppress the muscle oxygen consumption inducing by high intensity exercise.
