The purpose of this study was to determine the effects of dehydration on muscular strength, endurance, power, and perceptual measures in resistance-trained women. Ten resistance-trained women completed 2 bouts of exercise (1 repetitionmaximum[1RM] for bench press and angled leg press followed by 5 sets to failure of 75%of 1RM and vertical jump), either dehydrated (;3% body mass) (DT) or heat-exposed with fluid replacement (HT). Paired t-tests revealed bench press 1RMwas significantly lower for DT (42.7614.5 kg) comparedwith HT (44.1613.9 kg). No significant differencewas found for leg press 1RM(DT5216.1655.0 kg; HT5223.4655.7 kg). There was also no difference in total reps completed for bench press (DT5 33.5 65.0; HT 5 33.0 65.5) or leg press (DT 5 42.6 620.3; HT 5 45.8 619.7). There was no significant difference for vertical jump height (DT: 45.8 6 5.2 cm, HT: 46.9 6 6.0 cm). Ratings of perceived exertion (RPE) and session RPE were not significantly different between trials. Significant differences for perceived recovery status (DT: 5.1 6 2.2, HT: 7.2 6 1.1) and perceived readiness (DT: 4.2 6 1.0, HT: 2.5 6 0.5) indicate subjects expected impaired performance during DT. The current results suggest that previous night dehydration may have a negative impact on both bench press 1RM performance and perceptual feelings of recovery in resistancetrained women.
