摘要

高強度訓練或比賽的過程中，身體大量流汗造成脫水與電解質流失進而降低運動表現能力，本研究目的為探討補充海洋性礦物質對脫水後復水之影響。本研究徵召8名年輕男性為受試者，採雙盲交叉實驗設計，將所有受試者平分成安慰劑組與海洋性礦物質組，於高溫環境進行單次中強度運動至脫水體重的3%，補充脫水量1.5倍的水份，在脫水後4小時內測量尿液量，並在脫水後24及48小時測量體重、尿液顏色、紅血球與血比容。本實驗結果發現補充水份後24小時體重已經恢復至脫水前，但是兩組無顯著差異。補充海洋性礦物質於4小時內所產生的尿液量高於安慰劑組。紅血球數目與血比容於補水後24與48小時低於脫水前，但是兩組無顯著差異。尿液顏色於補水後24至48小時高於脫水前，但是補充海洋性礦物質於24小時的尿液顏色低於安慰劑組。本研究結論為補充海洋性礦物質可以加速身體恢復的程度，建議補充海洋性礦物質來促進身體的復水。

Rapid sweating during high-intensity exercise training or competition leads to dehydration and loss of electrolytes, thereby result in decreasing exercise performance. The purpose of this study was to investigate the effects of deep ocean minerals supplementation on the balance of hydration status following dehydration. The crossover experimental design was used in this study. Eight young male subjects received either placebo (PLA) or deep ocean minerals (DOM) trails. Each trail was separated and repeated the same protocols after one week washout period. Subject performed a single bout of moderate-high intensity exercise in a high temperature environment in order to loss 3% body weight. After exercise subjects received either deep ocean minerals or PLA supplements (equivalent to 1.5 times of body weight losses) to replace their fluid losses. Body weight, urine color, red blood cells and hemotocrit were measured 24 and 48 hours following dehydration. We found that the loss in body weight after dehydration was regained to pre-dehydration level within 24 hours in both trails. The urine volume in DOM trial was significantly increased within 4 hours compared to PLA trail. The red blood cell number and hemotocrit after dehydration were significantly lower than pre-dehydration level in both trials; however no significant difference between PLA and DOM trails. The DOM trail significantly decreased the urine color compared to the PLA trail. Our results demonstrated that supplementation of deep ocean minerals can increase the recovery status following intense exercise. This study suggests that deep ocean minerals supplementation is effective to promote the rehydration status.
