| Abdel-Baki et al. (2013) | To assess the feasibility of implementing a 14-week aerobic interval training (AIT) program and its efficacy in improving metabolic outcomes and cardiorespiratory fitness | Twenty-five (16 completed) male subjects with FEP | No control group. VO2 max was estimated with the single treadmill walking test, anthropometric measures, metabolic profiles (fasting blood work), blood pressure, resting heart rate, body composition was estimated by bioelectric impedancemetry analysis. Other measures: Clinical Global Impression Severity Subscale (CGI-S), Global Assessment of Functioning Scale (GAF), Social and Occupational Functioning Assessment Scale (SOFAS) | Aerobic interval training (AIT) involved a supervised session of warm-up and treadmill running twice a week (14 weeks) | A significant decrease in waist circumference (WC; −4.3 cm; p = 0.015), resting heart rate (−8.6 bpm; p = 0.05) and a 38% increase in VO2 max (p = 0.001). No significant change in blood pressure, lipid profile, glucose metabolism or psychiatric measures |
| Firth et al. (2018) | Assess the feasibility of an exercise intervention for early psychosis and to determine if it was associated with changes in physical and mental health | Intervention N = 31 comparison control group N = 7 patients with FEP recruited from early intervention services | Non-randomised feasibility trial using comparison data from the treatment-as-usual (TAU) control group. Measures: Positive and Negative Syndrome Scale (PANSS), Becks Depression Inventory (BDI-II), Social Interaction Anxiety Scale (SIAS), Socio-Occupational Functioning Assessment Scale (SOFAS), WHO Disability Assessment Schedule (WHODAS), WHO Quality of Life Brief (WHOQOL-BREF), body mass index, waist | 10-week individualized exercise intervention, aiming to achieve ≥90 min of moderate-to- vigorous activity per week | Retention: 81%. On average, participants achieved 107 minutes of moderate-to-vigorous exercise each week. PANSS scores decreased by 13.3 points, significantly more than control group. Psychosocial functioning and verbal short-term memory were significantly improved. Increases in cardiovascular fitness and processing speed were positively associated with the amount exercise |
