Abstract
Objective:
To evaluate the feasibility and effects of a 12-week intervention combining aerobic and strength exercises in prison inmates with psychiatric disorders.
Design:
Two parallel-group, randomized controlled trials.
Setting:
A psychiatric prison hospital.
Subjects:
Forty-one men prison inmates (mean age ± SD = 38.2 ± 9.2 years, mean prison duration ± SD = 2.6 ± 2.5 years) with psychiatric disorders (primarily personality disorder, n = 27; mean illness duration ± SD = 12.0 ± 10.5 years).
Interventions:
Participants were randomly allocated to intervention group consisted of exercise plus usual care (n = 21) or control group which received usual care (n = 20) for 12¿weeks. 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 ...

Interventions:
Participants were randomly allocated to intervention group consisted of exercise plus usual care (n = 21) or control group which received usual care (n = 20) for 12¿weeks. 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.
