Acute effect of three different warm-up protocols on maximal isokinetic strength in young men

Abstract

Objective: To investigate the acute effect of three different warm-up protocols on a maximal isokinetic strength test.
 Methods: Twenty-two male, recreational athletes involved in regular resistance training were evaluated. Subjects performed a maximal isokinetic strength test of the knee extensors in an isokinetic dynamometer after completing a control session or one of the following warm-up protocols using a randomized design: a general warm-up, stretching warm-up, or specific warm-up. The comparison between treatments was completed through Repeated-Measures Analysis of Variance, followed by a Bonferroni “post hoc” test (p < 0.05).
 Results: The only difference found was the concentric peak moment following the application of the specific warm-up protocol, which was lower than the control session (12.94%; p < 0.05). No other differences were noted in eccentric peak movement or total work (concentric + eccentric) parameter after application of any the warm-up protocols within control condition (p > 0.05).
 Conclusion: The finding of this investigation showed that none of warm-up protocols applied were able to change the total work of maximal isokinetic strength. Thus, our investigation suggests that the general warm-up, stretching warm-up and specific warm-up have had no adverse or improved effectiveness on acute muscle strength capacity.

Effects of static stretching and specific warm-up on the performance in upper- and lower-limb exercises in resistance-trained older women

“…Our study did not observe improved lower limb performance after SW. As for the upper limbs, SW resulted in decreased repetition performance compared to SS and CC. This result is intriguing because SW are frequently related to improvements in acute performance in resistance exercises (1,16,21,23), although this is not universal (20,22). This nding may be associated with the upper limbs characteristics.…”

Warming-Up for Resistance Training and Muscular Performance: A Narrative Review

“…In the study of Rodrigues and collaborators, [23] three different types of warmup were compared: a general warm-up, a specific warm-up, and a warm-up through stretching, to understand whether it would influence maximal isokinetic training. The results reported that the three types of warm-up had no adverse effect or any type of improvement in acute muscle strength.…”
