maximized at 1RM. However, previous studies have reported that submaximal loads are optimal for peak power output during HPC. 6 – 10 There are 2 possible explanations for these results. First, the movement might not be executed correctly at heavy loads. Because it is not easy to perform ballistic exercises

Peak power output did not differ between conditions ( p  = .644), but a difference was observed over time ( p  < .001), with peak power output significantly higher in the first sprint compared with the third

Similarly, Aoki et al 7

This reduction in power output matches the ∼30% reduction in PDH and estimated glycogenolysis during a 1-min sprint at 150% of peak power output

.1% improvement in mean and peak power output, respectively ( Wiles et al., 2006 ). Such performance benefits have also been realized during short-duration maximal dynamic resistance training exercise, where measures of muscle torque production were significantly improved after the consumption of 6 mg/kg caffeine

commonly reported but inappropriate food selection may affect an athlete’s energy availability and gut comfort. A state of low-carbohydrate availability has been shown to impair anaerobic work capacity ( Langfort et al., 1997 ) and peak power output ( Wroble et al., 2018 ). However, this effect is evident

During short-term, supramaximal, and repeated sprint tasks, 3–6 mg/kg BM of caffeine taken 50–60 min before exercise results in performance gains of >3% for task completion time, mean power output, and peak power output during anaerobic activities of 1
