BACKGROUND: Warm-up is considered essential to optimize running performance, but little is known about the effect of specific warm-up tasks, specifically in the real competitive context. The current study aimed to verify the acute effects of a warm-up including ballistic exercises in 30m running performance. In addition, a second 30m trial was assessed to better understand the warm-up effects in training/competition.
METHODS: Twenty-two men (19.32±1.43 years-old) randomly completed the time- trials on separate days and after a typical warm-up (WU), a WU complemented with ballistic exercises (post-activation potentiation - PAP) or no warm-up (NWU). Biomechanical, physiological and psychophysiological variables were assessed.
RESULTS: The participants were 1.9% faster in the first 30m sprint after WU compared with NWU, mainly increased performance in the first 15m (p=0.03, ES=0.48). WU resulted in greater stride length in the last 15m of the first sprint. PAP did not differ from NWU and WU, despite eight participants performed better after this warm-up.
CONCLUSIONS: These results highlight the positive effects of warm- up for sprinting, despite failed to evidence positive effects when ballistic exercises are included. In addition, the influence of warm-up in the running technique was highlighted by the changes in the running kinematics and a need for individualization of warm-up procedures.
Sports performance is influenced by the interaction of several physical variables. For this reason, most sports need both strength and endurance capacities to maximize overall performance. Therefore, a combination of resistance and aerobic training, usually called concurrent training (CT), has been used recently as a way of simultaneously improving strength and aerobic performances according to the needs of a specific sport. This combination can be challenging and can influence training adaptations, being a problematic issue for coaches. The main objective is to provide coaches with a practical proposal for CT to improve athletes' performance in different sports.
