The purpose of this study was to investigate the effect of water and energy substrate intake on the volume of body fluid and percent body fat. Two experiments were carried out using young and healthy subjects. In the first experiment, 48 subjects consumed total volume of 1.2 L of water and body composition measurement was taken. In the second study, total 37 subjects were used, and randomly allocated to four experimental groups: control (CON, n=9), carbohydrate supplement (CHO, n=10), creatine supplement (Cre, n=9), and carbohydrate and creatine supplement (CHO+Cre, n=9). Carbohydrate was provided to intake 40 g for each time, 3 timesㆍd?¹ for 3 days, and creatine was given to consume 5 g for each time, 6 timesㆍd?¹ for 5 days. For subjects who were in CHO+Cre, carbohydrate was given for 3 days and creatine was given for 5 days. After consume 1.2 L of water, % body fat (%BF) and skeletal muscle mass increased by 3.3% (17.9±4.9% [pre] vs. 18.5±4.7% [post]) and 2.2% (26.7±6.6 ㎏ [pre] vs. 27.3±6.6 ㎏ [post]). With Consuming of energy substrate (either CHO or Cre), there was only significant increase in body mass (BM) in CHO + Cre. Interestingly this was induced by increased skeletal muscle mass rather than increased body fat mass. As far as body fat measurement is concerned, skin fold thickness was not affected by consuming energy substrate whereas %BF was shown significant increase when near infrared interactance measurement was adopted. Base on these results, following conclusions were drawn. Using bioimpedance analysis, water or fluid consumption would significantly ncrease in % body fat. Short term carbohydrate or creatine intake would not cause to increase in body mass and/or %BF. Short term creatine intake would not cause to increase in body mass and/or %BF. Intaking both carbohydrate and creatine simultaneously for short period of time may possibly cause to increase in total body mass, as well as skeletal muscle mass or %BF. Percent BF or total BF mass may differently evaluated by using different techniques, that needs to be examined far more researches.
