| Abstract |
The aim of this study was to evaluate the acute effect of a single dry sauna bath lasting twelve minutes on the indirect determination of the one maximum repetition (1RM) leg press among trained and untrained participants. Thirty young men participated in the study, a trained group (TG; n = 15; age: 20.97 +/- 0.44 years) and an untrained group (UG; n = 15; age: 21.03 +/- 0.11 years). Subjects in the TG had performed resistance training for at least two years before the beginning of the experiment. All participants performed two indirect tests of their one maximum repetition leg press on two different days, with a rest period of three weeks between tests. Additionally, anthropometric, body composition, blood pressure, body temperature, and rated perceived exertion were evaluated. On the second testing day, all of the participants took a dry sauna bath lasting 12 min immediately before performing the leg press test. In the second evaluation (pre-heating in the sauna), the UG experienced increases in absolute RM (178.48 +/- 56.66 to 217.60 +/- 59.18 kg; p < 0.05; R = 0.798), relative RM (2.65 +/- 0.61 to 3.24 +/- 0.58 kg center dot g body mass(-1); p < 0.05; R = 0.798), and muscular RM (5.64 +/- 1.20 to 6.77 +/- 1.14 kg center dot kg muscle mass(-1); p < 0.05; R = 0.797). The TG also increased their values on the second day in absolute RM (284.96 +/- 62.41 to 314.92 +/- 1.04 kg; p < 0.01; R = 0.886), in relative RM (3.61 +/- 0.88 to 3.99 +/- 1.85 kg*kg body mass(-1); p < 0.01; R = 0.886), and muscular RM (7.83 +/- 1.69 to 8.69 +/- 1.85 kg center dot kg muscle mass(-1); p < 0.01; R = 0.854). A passive, extreme-heat sauna bath lasting 12 min taken immediately before a relative maximum repetition test seems to provoke clear positive responses for the development of strength. |
