The purpose of this study was to compare the effectiveness of 3 treatment modes [Anti-Gravity Treadmill (G-trainer), stationary cycling (CompuTrainer), and static stretching] on the physiological and psychological recovery following an acute bout of exhaustive exercise. In a cross-over design, twelve aerobically-trained males (21.3+/-2.3 yrs., 72.1+/-8.1 kg, 178.4+/-6.3cm, VO2peak: 53.7+/-6.3 ml/kg/min) completed a 29 km stationary cycling time trial. Immediately following the time trial, subjects completed 30 minutes of G-trainer or CompuTrainer (40% VO2peak) or static stretching exercises. A significant time effect was detected for plasma lactate (p=0.010) and serum cortisol (p=0.039) post exercise. No treatment or treatment by time interaction was identified for lactate or cortisol, respectively. No main effects for time, treatment or treatment by time interaction were identified for interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF[alpha]). No differences were observed among treatments in skeletal muscle peak power output, mean power output, time to peak power, and rate to fatigue at 24 hours post exercise bout. Finally, no significant changes in mood status were observed following exercise and/or between treatment groups. When compared to stationary cycling and static stretching, exercise recovery performed on the G-trainer was unable to reduce systemic markers of stress and inflammation, blood lactate, or improve anaerobic performance and psychological mood states following an exhaustive bout of endurance exercise. Further research is warranted that includes individualized recovery modalities to create balances between the stresses of training and competition.
