Registered summary

The goal of this study is to investigate the effect of combining olive leaf extract supplementation with endurance training (moderate intensity continuous training or sprint interval training). We hypothesize that OLE supplementation during training, as compared to training alone with placebo, will translate into better performance outcomes. More specifically, we hypothesize that the additional benefits of OLE supplementation on performance will be mediated by improved mitochondrial characteristics in skeletal muscle and increased neural activation.

Where, as registered
