Data for: The effects of vitamin D3 supplementation on the aerobic and anaerobic exercise performance of recreational combat sport athletes

Data associated with the PhD thesis 'The effects if vitamin D3 supplementation on the aerobic and anaerobic exercise performance of recreational combat sport athletes'.

Study 1 investigated the dose response of weekly vitamin D3 supplementation of different doses in recreational combat sport athletes with respect to aerobic and anaerobic exercise performance (Marley, A., Grant, M. C., & Babraj, J. (2021). Weekly vitamin D3 supplementation improves aerobic performance in combat sport athletes. European Journal of Sport Science, 21(3), 379-387. https://doi.org/10.1080/17461391.2020.1744736).

Study 2 supplemented either vitamin D3 or a placebo for six weeks combined with twice-weekly sprint interval training in recreational combat athletes to ascertain of vitamin D3 could possess an additive effect to sprint interval training (Marley, A., Grant, M. C., & Babraj, J. (2022). Vitamin D3 supplementation combined with sprint interval training improves aerobic and anaerobic exercise performance over sprint interval training alone in recreational combat sport athletes. Science and Sports, 37(3), 217.e1-217.e10. https://doi.org/10.1016/j.scispo.2021.07.004).

Study 3 supplemented either vitamin D3 or a placebo for two weeks combined with two weeks of hill sprint and battling rope training to ascertain the effect on repeated sprint ability and strength in recreational combat athletes.
