About

The purpose of the present study is to investigate the effect of different rate of fluid consumption on post-exercise rehydration.

Full description

The body water deficits equivalent to 2% body mass might impair performance. Due to high exercise intensity, thermal environment, or rule limitation, athletes often in dehydration status post-exercise. Thus, how to rehydrate effectively to prepare the next game is important. The participants arrived to the lab euhydrated and were dehydrated to 2% of body weight by running. After a rest, they will ingest sports drink in a volume equivalent to 150% of BW loss in 30 min, 60 min, or 90 min. Urine and blood sample will be collected to evaluate hydration status.
