Effects of Coffee on Physical Performance in Mice

In this study, coffee was shown to effectively inhibit L6 muscle cell death and ATP reduction induced by hydrogen peroxide damage. Additionally, two weeks of oral administration of 7 mg/kg coffee extracts to mice resulted in a 33% increase in treadmill running time relative to that seen in the distilled water administered group. Blood analysis showed decreased lactate content, which was increased by exercise. Thus, these data suggest that coffee intake may enhance exercise capacity and inhibit damage due to excessive exercise.
