Brief Summary
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?

Outcome Measures
Primary Outcomes (1)
Total forearm work performed
Work is the product of the number of times the forearm is activated multiplied by the amount of force produced by the forearm in kilograms.
During the forearm exercise fatigue protocol lasting up to 45 minutes
Secondary Outcomes (2)
Forearm endurance
During the forearm exercise fatigue protocol lasting up to 45 minutes
Intermuscular coordination
During the forearm exercise fatigue protocol lasting up to 45 minutes
Study Arms (4)
Beet-root juice plus red-light therapy
EXPERIMENTALBeet-root juice plus sham light therapy
SHAM COMPARATORPlacebo plus red-light therapy
PLACEBO COMPARATORPlacebo plus sham light therapy
ACTIVE COMPARATORInterventions
Two days prior to the forearm endurance protocol, participants will be provided and instructed to consume a 400mg nitrate once per day. On the day of the forearm endurance protocol, the participants will be provided and instructed to consume a third 400mg dose of nitrates at least 150 minutes before forearm endurance testing.
Participants will place their dominant forearm 15 centimeters away from the light source and have their dominant forearm exposed to 660nm wave length light for 10-minutes.
Two days prior to the forearm endurance protocol, participants will be provided and instructed to consume a nitrate depleted placebo once per day. On the day of the forearm endurance protocol, the participants will be provided and instructed to consume a third dose of the nitrate depleted placebo at least 150 minutes before forearm endurance testing.
Participants will place their dominant forearm 15 centimeters away from the light source and have their dominant forearm exposed to sham light for 10-minutes.
