About the study
The goal of this randomized counterbalanced repeated measures study is to test beet-root juice supplementation and red light therapy augment forearm muscle endurance in apparently healthy older adults over 65 years of age. The main questions seek to answer the following question:
Does beet-root juice supplementation improve forearm muscle endurance compared to a placebo supplement?
Does red light therapy improve forearm muscle endurance compared to a sham light exposure?
Does beet-root juice supplementation in combination with red light therapy improve forearm muscle endurance compared to a placebo-sham light control?
What is being tested
- Beet-root juice (dietary supplement)
- red-light therapy (radiation)
- Placebo (dietary supplement)
- sham light (radiation)
