Abdel-Baki, A., Brazzini-Poisson, V., Marois, F., Letendre, É. et Karelis, A. D. (2013). Effects of aerobic interval training on metabolic complications and cardiorespiratory fitness in young adults with psychotic disorders: A pilot study. Schizophrenia Research, 149(1), 112-115.
Aim: To assess the feasibility of implementing a 14-week aerobic interval training (AIT) program within a first-episode psychosis (FEP) service and its efficacy in improving metabolic outcomes and cardiorespiratory fitness.
Method: Twenty-five male subjects participated in 30-minute sessions of AIT twice a week.
Results: Sixteen of 25 subjects completed the training program. There was a significant decrease in waist circumference (WC; −4.3 cm; p = 0.015), resting heart rate (−8.6 bpm; p b 0.05) and a 38% increase in VO2max (p b 0.001). The decrease in WC(−5.6 cm; p b 0.01) was more pronounced for subjects who completed at least 64% of the planned sessions.
Conclusion: An AIT program could be implemented in FEP patients and improve WC and cardiorespiratory fitness over a relatively short period.
