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. Red spinach extract has been shown to be beneficial in exercise performance, albeit mostly in aerobic exercise. In a previous study in our lab, we found that dietary nitrate consumption resulted in significantly greater isometric force production in teenage males. However, currently there is little know regarding the effects of dietary nitrate supplementation on isometric strength, resistance exercise and cognitive performance.
详细描述
This research study is designed to measure the effects of red spinach extract (RSE) on markers of physical and cognitive performance during and following anaerobic exercise.

入选标准
- •18-34 years old Participants must have at least 1 year of resistance training experience.
- •Free of any physical limitations, medications, and supplements that may affect performance, as determined by a health and activity questionnaire.
- •Are free of musculoskeletal injuries
- •Are not taking medications that may interfere with study measurements
排除标准
- •Participants that cannot take either the RSE or placebo supplement will be excluded, as this will be a double-blind study.
- •Furthermore, participants that cannot participate in pre- and post-research testing, and/or those that cannot commit to regular training sessions will be excluded.
- •Inability to perform physical exercise (determined by health and activity questionnaire)
- •Taking any other nutritional supplement or performance enhancing drug.
- •Any chronic illness that causes continuous medical care
