Clinical Trial Summary

The purpose of this study is to examine the effect of varying nitrate doses of beetroot juice supplementation on dynamic, multijoint resistance exercise performance in active, trained individuals. Performance will be assessed based on parameters including neuromuscular efficiency, anaerobic performance capability, oxygen consumption, plasma nitrate/nitrite levels, specific muscle tissue biomarkers including lactate, and anthropometric measurements of select muscle groups.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Muscle activation and fiber recruitment	Muscle activation/fiber recruitment to be measured in millivolts (mV) using electromyography (EMG) sensor during maximum voluntary contractions (MVC) and compared between study arms.	5 weeks
Secondary	Plasma nitrate/nitrite levels	Plasma nitrate and nitrite levels will be measured at baseline and after 7 days of supplementation and compared between study arms.	5 weeks
Secondary	Number of repetitions performed	Total number of repetitions in each session and number of repetitions performed at each respective % of 1 repetition maximum during each session will be recorded and compared between study arms.	5 weeks
Secondary	Oxygen consumption	Total oxygen consumption during testing sessions will be recorded and compared between study arms.	5 weeks
