简要总结
Red Spinach is a natural food which is a rich source of nitrates, which are beneficial in hemodynamics, cardiovascular function, and have natural hypotensive and antianginal effects . In recent research, Red spinach extract has been shown to be beneficial in acute exercise performance. However, currently it is unclear how these acute increases in performance may translate to long term training adaptations.
This research study is designed to measure the effects of red spinach extract (RSE) on markers of physical performance, body composition, and health following chronic resistance training and anaerobic exercise.
详细描述
The investigators aim to measure muscle strength, athletic performance, body composition, and muscle size in two groups of adults before and after 11 weeks of intervention in a randomized, double blinded study. One group (n=15 ) will receive an intervention of resistance exercise and a Red Spinach Extract supplement, and the other group (n=15) will receive resistance exercise and a placebo (maltodextrin).
