The study we are proposing will use this measurement (i.e. ratio of low frequency force to high frequency force output) as a more direct measure of muscle damage. We predict that if cherry juice is consumed in the days leading up to a bout of muscle-damaging endurance exercise, muscle damage will be lower (as indicated by a faster recovery of low-frequency fatigue following the bout of exercise) than when a comparison-drink (i.e. Gatorade) is consumed.
