LIMA, Fernando Vitor et al. Efeito da amplitude de movimento no número máximo de repetições no exercício supino livre. Rev. Bras. Educ. Fís. Esporte [online]. 2012, vol.26, n.04, pp.571-579. ISSN 1981-4690.

There are divergent results about increases in strength using different ranges of motion (ROM). The aim of this study was to compare the maximum number of repetitions (MNR) in bench press with two different ROM. Fourteen subjects performed familiarization and one repetition maximum (1 RM) tests in sessions 1 and 2. MNR in four sets at 50% of 1 RM, one-minute rest with partial (ROMP) and complete ROM (ROMC) were performed in the third and fourth sessions. The ROMP used half of the bar vertical displacement compared to ROMC. Two-way ANOVA with repeated measures was used to compare the experimental conditions, followed by post hoc Scheffé. There was a significant decrease of the MNR among sets, except from third to fourth sets in both ROM. MNR in all sets was higher in ROMP than ROMC. The reduction of ROM allow to perform higher number of repetitions.
