Determinación del perfil funcional "entrenados" y "no entrenados" según la velocidad de la barra en el press de banca

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 (1RMBW), cuando esta relación es inferior a 1 (1RM<BW), los sujetos se pueden catalogar como no entrenado en PB. Además, este estudio demuestra que los sujetos entrenados con una carga de 20 kg, logran velocidades de la barra superiores a 1.2 ms-1 y los sujetos no entrenados logran velocidades inferiores
