The purpose of this study is to examine how certain kinds of fruit juice that contain natural antioxidants and natural anti-inflammatory properties may reduce exercise-induced muscle pain and injury. Participants will be recruited from registered participants in the Hood To Coast Relay. The Hood To Coast Relay Race Officials will post the study on their website to find interested teams. Interested participants will then be contacted by the study staff by phone regarding the study's inclusion and exclusion criteria and to schedule the initial health screening visit. The participants will undergo an initial health screening and survey about muscle soreness, and then drink the investigational juice twice daily for 8 days. On the 7th day of drink administration, the participants will report to the starting location of the Hood To Coast Relay to meet with the investigators for 30 minutes to survey muscle pain and juice tolerability. The participants will then participate in the Hood To Coast Relay, drinking 2 more bottles of juice over the duration of the relay. At the conclusion of the relay, the participants will meet with study investigators to take the same short survey about muscle pain and juice tolerability.

Further study details as provided by Oregon Health and Science University:

Primary Outcome Measures:
  • The administration of tart cherry juice will reduce the symptoms of exercise-induced muscle damage as measured by patients assessment of pain on a standard VAS. [ Time Frame: Post Race ]

Estimated Enrollment: 100
Study Start Date: August 2008
Estimated Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Tart cherry juice
Dietary Supplement: Tart Cherry Juice
Participants will ingest 10.5 fl oz of cherry juice twice a day for 7 days prior to the race, and the day of the race (8 days total).
Other Name: Cherrish
Placebo Comparator: 2
Fruit juice
Dietary Supplement: Fruit juice
Participants will ingest 10.5 fl oz of fruit juice twice a day for 7 days prior to the race, and the day of the race (8 days total), which will serve as a 'placebo' juice.
