- Abstract
The purpose of this study was to determine the effects of arm span on the acute effects of fatigue caused by maximum voluntary isometric contraction (MVIC) on performance in the bench press. Eight female collegiate track and field athletes involved in the throws events (shot put, discus, hammer, and javelin) volunteered for this investigation. Initial assessments included one-repetition maximums in the bench press (Pre Max 59.5±19.8kg) for each volunteer as well as basic anthropometric data including arm span. Volunteers reported twice for two treatments that included three maximal bench press attempts. The standard (STAND) treatment consisted only of the maximal attempts. The MVIC treatment consisted of a 30-second maximal voluntary isometric contraction prior to maximal attempts. General Linear Model analysis was performed to evaluate fixed effects (Treatment, Arm span) on maximum weight lifted. The model was significant (Likelihood Ratio Chi-Square 3507.525, p<0.001) and revealed main effects for treatment (STAND 59.78±18.8kg vs. MVIC 52.32±11.5kg, p<0.001) and arm span (p<0.001), as well as a significant two-way interaction treatment*arm span (p<0.001). Post-Hoc analysis revealed that under the STAND treatment arm span was not a predictor of change in bench press performance; however under the MVIC treatment (F=16.255, p=0.007) arm span was a significant negative predictor of change in bench press performance (Beta = -0.855, p<0.001). Arm span is a simple measure that can quickly and easily be assessed; yet also a variable that can provide valuable information for coaches to consider before planning weight training for track and field throws athletes.
