Abstract

The purpose of this study was to examine the effects of dehydration and rehydration on the one repetition maximum (1-RM) bench press of weight trained males. The ten subjects displayed the following characteristics: 25.3 ± 3.2 years old, 85.5 ± 16.4 kilograms body mass and a 117.9 ± 24.0 kilogram base-line 1-RM. Ten subjects were tested on two separate days, with one week between each test day. The subjects were randomly assigned to begin their testing in either the A protocol or the B protocol. During the A protocol testing day, the subjects completed two one repetition maximum bench press protocols in the euhydrated state, with a two hour break between the protocols. During the B protocol testing day, the subjects completed two one repetition maximum bench press protocols, one in the dehydrated state and the other in the rehydrated state, with a two-hour break between the protocols. The subjects were passively dehydrated in a sauna. All variables were measured during each trial. The data were analyzed for differences among the trials using a repeated measure ANOVA. Dehydration resulted in a significant decrease in the 1-RM bench press (p=0.0015), when compared to the euhydration-one 1-RM. There was no significant difference between the euhydration-one and the rehydration 1-RM bench press. There was a significant increase in the 1-RM bench press, when comparing the dehydration trial to the rehydration trial (p=0.0023). The following variables decreased significantly (p
