Tart Cherry Juice Reduces Muscle Pain and Inflammation

Antioxidant and anti-inflammatory properties also give Montmorency cherries bitter flavor
Tart cherry juice may be a safer way to treat muscle pain and inflammation than over-the-counter pain relievers such as ibuprofen, according to researchers at Oregon Health & Science University.
A study of athletes who competed in Oregon’s Hood to Coast Relay showed runners who consumed Montmorency cherry juice for a week prior to the race and on race day reported significantly less pain than runners who received a placebo. Hood to Coast is a 197-mile race from Mount Hood to Seaside, Ore., that involves 1,000 eight- to 12-person relay teams.
“The bottom line is those runners who used tart cherry juice had less inflammation and faster muscle strength recovery,” said Kerry Kuehl, M.D., associate professor of medicine (health promotion and sports medicine) in the OHSU School of Medicine and the lead author on the study. The results were published in a recent issue of the Journal of the International Society of Sports Nutrition.
Montmorency – or sour pie cherries – have the highest anti-inflammatory content of any food, including blueberries, pomegranates and other fruits. The anti-inflammatory substance found in the peel of the fruit contains the same enzyme as over-the-counter anti-inflammatory drugs like ibuprofen.
Non-steroidal anti-inflammatories are the most widely used drug in the world. An estimated 60 million people take a prescription or over-the-counter anti-inflammatory, including aspirin, every day. However, regular use of anti-inflammatory drugs can lead to kidney failure, heart and stomach problems.
“There are an estimated 100,000 hospitalizations and 16,500 deaths per year due to internal bleeding caused by non-steroidal anti-inflammatories,” Kuehl says. “Dehydration in combination with non-steroidal anti-inflammatory use – which is common among runners – can damage the kidneys. Montmorency cherry juice may be a healthier substitute.”
The study measured pain reduction among a group of runners who participated in the 2009 Hood to Coast run. The runners consumed 10½ ounces of Montmorency cherry juice twice a day for seven days prior to the race and then drank that amount every eight hours on race day. None of the study participants were taking any other pain relievers.
The juice used in the study was provided by Cherrish Inc. There was no outside funding for the study.
Kuehl and other researchers are conducting further studies on cherry juice, including research on how key ingredients help rebuild muscle.
Oregon Health & Science University is the state’s only health and research university, and Oregon’s only academic health center. OHSU is Portland's largest employer and the fourth largest in Oregon (excluding government). OHSU's size contributes to its ability to provide many services and community support activities not found anywhere else in the state. It serves patients from every corner of the state, and is a conduit for learning for more than 3,400 students and trainees. OHSU is the source of more than 200 community outreach programs that bring health and education services to every county in the state.
