Previous studies have reported traditional static stretching maneuvers to negatively influence muscle strength endurance, while sport-specific warm-ups have grown in popularity due to their potential to improve subsequent performance. However, it is possible that the volume of the warm-up may also influence muscle strength endurance (MSE).
PURPOSE: The purpose of this study was to examine the acute effects of different volumes of a sport specific warm-up on MSE performance.
METHODS: Twenty-six healthy, recreationally active males [(mean ± SD) age, 22.2 ± 1.3 years; height, 179.0 ± 7.0 cm; weight, 83.0 ± 10.3 kg] volunteered for this study. Of the 26 participants, 20 reported engaging in 2-5 h·wk−1 of aerobic exercise, 21 reported engaging in 2-8 h·wk−1 of resistance training exercise, and 17 reported engaging in 1-6 h·wk−1 of recreational sports. Each subject performed 3 randomly ordered conditions [control, sport-specific warm-up (WU1), and the sport specific warm-up with twice the volume (WU2)] following a 5 min light jog. During the control trial, each subject sat and rested for 12 minutes following the light jog. The sport specific warm-up included a dynamic warm-up routine gradually progressing in intensity. MSE was assed at 70% of each subject's one-repetition maximum (1-RM) on a leg press machine. During the MSE test, subjects performed as many repetitions as possible until failure following each condition. A one-way ANOVA [control vs. WU1 vs. WU2] was used to analyze MSE with an alpha level of 0.05 set for statistical significance.
RESULTS: There was a significant difference in MSE among conditions, where the WU2 (19.5 ± 5.6) condition resulted in significantly less repetitions (P = .009) when compared to both the CON (22.7 ± 6.0) and WU1 (22.3 ± 6.7) conditions.
CONCLUSION: The results of the present study suggest that an increase in the volume of a sport specific warm-up can decrease MSE in recreationally active males. In addition, there was no increase in MSE for the WU1 condition when compared to the CON condition.
PRACTICAL APPLICATION: These findings may be important for strength & conditioning professionals in determining the appropriate volume of a sport specific warm-up to effectively improve athletic performance.
