Static stretching (SS) practices can result in acute anaerobic performance reductions with an associated
reduction in neural muscle input. The purpose of this study was to determine whether the neural stimulus of caffeine
intake would sufficiently minimize or remove the potential inhibitory effect of acute SS on anaerobic performance
measured by a 30‐s all‐out Wingate Anaerobic Test (WAnT). Twelve(12) recreational male athletes performed the WAnT
under six conditions, namely a no‐treatment control condition, an SS condition (nine lower‐body SS exercises), a placebo
condition (6 mg∙kg‐1 maltodextrin), a placebo combined with SS condition, a caffeine condition (6 mg∙kg‐1) and a caffeine
combined with SS condition. Peak power output (PPO), average power output (AvPO) and maximal revolutions per
minute (RPMmax) were measured. SS resulted in significantly lower PPO values (p = 0.005), RPMmax values (p = 0.014),
and longer tPPO (p = 0.036) compared to the control condition. The condition of SS in combination with caffeine intake
resulted in significantly higher PPO (p = 0.004), AvPO (p = 0.025) and RPMmax (p = 0.000) values compared to the
condition of SS only. In addition, the control condition showed significantly lower values in PPO (p = 0.029), AvPO (p
= 0.008), and RPMmax (p = 0.018) variables compared to the caffeine condition, whereas no significant difference (p =
0.260–0.567) was observed when compared with the caffeine and SS combination condition. The results of this study
confirm the negative effects of SS on anaerobic performance while demonstrating that caffeine intake may minimize or
counterbalance these effects. Additionally, the potential risk that SS may partially diminish the positive effects of caffeine
should not be overlooked
