From the elite competitor, to the weekend athlete, or as a result of everyday activities, muscle injuries are a way of life. To date, no studies have examined the effectiveness of the Alter-G G-Trainer to enhance muscle recovery from injury. Twenty-five recreationally active males between 18 and 35 were randomly assigned to one of three recovery groups: G-Trainer, treadmill running, static stretching. Recovery was performed 30 minutes, 24, 48, and 72 hours following a 45 minute downhill run. Isokinetic strength, creatine kinase, superoxide dismutase, malondialdehyde, muscle soreness and mood states were assessed at baseline, 15 minutes, 3, 24, 48, 72, and 96 hours post-exercise. Significant time effects were observed for isokinetic knee flexion/extension at 60 and 180°/second, muscle soreness (p<0.05), muscle soreness (p<0.001) and POMS (p=0.013). A significant group by time interaction (p=0.027) was observed for POMS. The G-Trainer treadmill was unable to enhance muscle recovery following exercise-induced muscle damage.
