Researchers from London South Bank University (LSBU) have found that drinking an antioxidant-rich cherry juice concentrate significantly improves muscle recovery from strenuous exercise.
LSBU researchers have found drinking cherry juice concentrate can help muscle recovery The LSBU research team, led by Dr Jo Bowtell, Head of LSBU's Sports and Exercise Science Research Centre, investigated the effects of CherryActive Concentrate on ten well-trained rugby, football and combat sport athletes, in two trials.
In the first trial, the athletes consumed 30ml of CherryActive, twice a day for ten days, and then for the other trial, the same amount of a placebo fruit concentrate.
After seven days of supplementation, participants completed ten sets of ten single leg knee extensions at 80 per cent of their maximum lifting weight. These exercises were designed to cause muscle fatigue and soreness and the recovery of muscle function was monitored over the following 48 hours.
Trials were completed at least two weeks apart to allow the supplements to wash out between trials and help eliminate any factors that could affect the accuracy of the results.
The participants also completed each trial with a different leg as it is well known that even a single strenuous exercise session will cause the muscle to adapt so that a second identical session will not cause the same degree of soreness.
The research found that muscle function after high-intensity exercise was significantly faster when participants were taking CherryActive, with their muscle strength returning to 91 per cent of their maximum strength within 24 hours after strenuous exercise.
Dr Jo Bowtell said: "This is great news for any serious athlete, sportsperson or gym user seeking to speed up the recovery of their muscle strength between intense training sessions. CherryActive is already widely used in the professional athletic community to aid recovery and this trial shows why.
"By reducing muscle recovery time, athletes should be able to increase their training volume and intensity and improve their performance."
CherryActive Concentrate has already been adopted by leading Premiership Football teams Manchester United and Everton, as well as England Rugby, the Lawn Tennis Association, and GB teams training for the 2012 London Olympic Games.
This research has been published in the American College of Sports Medicine's journal Medicine & Science in Sports & Exercise.
