The exercise programme included three weekly sessions of group-based moderate-to-high intensity combined exercises designed and supervised by exercise professionals.Main measures:Fitness and anthropometric measures were assessed using field-based tests (6-minute walk, Incremental Shuttle Walk, Arm-Curl, and Chair-Stand), handgrip dynamometry, bioelectrical impedance, and waist and hip circumferences.Results:There were no adverse events, and 10 intervention participants withdrew. The remaining 11 participants attended a mean of 28 sessions, of which nine met the compliance criteria. Between-group change differences substantially favoured the compliance intervention group for the 6-minute walk (+21.2%), Incremental Shuttle Walk (+33.9%), Arm-Curl (+13.8%), waist (¿3.5%), waist/height0.5 (¿1.7%) (¿2.7%), waist/hip (¿3.4%), and Body Shape Index (¿3.3%) (¿3.5%). Additional analysis showed beneficial effects of exercise participation on handgrip strength.Conclusion:The intervention was safe, had a high dropout rate, and seemed to be effective for improving fitness and anthropometric measures in men prison inmates with psychiatric disorders who attended and participated in the exercise sessions.
