Functional profile determination "trained" and "untrained" by the speed of the bar on the bench press

Abstract

A descriptive study was designed to explore differences in strength, power and velocity in an incremental load protocol in bench press (PB), to obtain an indicator to catalogue a subject as “trained“ or “untrained” in the PB exercise.. Thirty male subjects consisted two groups, “trained group”, consisted of the participants whose one repetition maximum (1RM) exceeded his body weight (BW) and “untrained group” consisted of participants whose 1RM was less than their BW. The value of 1RM was 82.33 ± 11.09 kg and 59.67 ± 5.16 kg, in the trained and untrained groups, respectively. The indicator of the level of strength (kg 1RM / kg BW) in the trained group was greater than 1, and lower in the untrained group. The average strength showed significant differences (p BW), while when this ratio is less than 1 (1RM<BW), subjects can be categorized as “untrained” in BP. Also this study demonstrates that “trained” subjects with a 20 kg load achieve bar speeds greater than 1.2 m•s-1, and “untrained” subjects achieve speeds less. Keywords: 1RM, Evaluation of the strength, functional profile, manifestations of strength.
