LOCAL MUSCULAR ENDURANCE AND PREDICTION OF 1 REPETITION MAXIMUM FOR BENCH PRESS LIFT IN DIFFERENT ATHLETIC POPULATIONS

Abstract : Desgorces, AU1 FD, Berthelot, G, Dietrich, G, and Testa, M. Local muscular endurance and prediction of the 1 repetition maximum for bench press lift in different athletic populations. J Strength Cond Res 24(x):000–000, 2009—The aim of this study was to determine a predictive equation of 1 repetition maximum (1RM) from local muscular endurance. Different athletic male populations were assessed: racket/ball games players (n = 31), power lifters (n = 22), swimmers (n = 28), and rowers (n = 29). After the 1RM assessment for the bench press, the maximum number of repetitions (MNR) relative to the 1RM (85%, 75%, 60%, 40%, and 20%) was tested. No significant differences in strength evolution from 20% to 100% of the 1RM was found between power lifters and racket/ball games players and between swimmers and rowers. However, differences in the strength evolution appeared between these 2 mixed groups (p , 0.01), with differences appearing from 75% of 1RM to lesser relative strength (p , 0.05). Nonlinear equations fitted best with the actual data for the capacity to repeat lifts. The evolution of strength from 100% to 20% of 1RM was better described when the groups’ specific equations were used as demonstrated by r2, and residuals range between the predicted minus the measured 1RM. The short evolution of strength (100%–75% of 1RM) was adequately modelled by the equation based on the total population sample. The accuracy of the 1RM prediction was better when a reduced number of lifts was performed. For untrained or novice subjects, the use of groups’ specific equation for all evolution of strengths allows for a good estimate of 1RM and provides adequate numbers of lifts for all levels of strength, thus optimizing the training programs.
