Summary

This study aims to evaluate the effects of beetroot juice supplements on lower-limb strength and muscular endurance in physically active women, due to the presence of NO3- in beetroot juice.

Detailed description

Beetroot juice (BJR) is used as an ergogenic aid, but no study has analyzed its' effects on explosive force production in physically active women. It has been proposed that females could blunt reduction of NO2- to NO based on a higher oxidative skeletal muscle phenotype than males. However, it has been observed a higher increase on plasma NO2- levels after supplementation compared to and a greater enhancement on muscle contractile function. Based on the absence of any study that has analyzed the effect of NO3- supplements on jump ability and power production on weightlifting on female population; the purpose of this study will be to investigate the possible ergogenic effect of BJR on physically active women on explosive force production and muscular endurance in a lower-limb body weightlifting protocol, due to the presence of NO3- in BJR and its effects.

Conditions

• Muscular Endurance
