The long-term effects of a 24-week outdoor exercise program in persons with schizophrenia: Results of a 12-week follow-up period

Abstract

This study aims to examine the long-term mental and physical health benefits of a 24-week outdoor exercise program after a 12-week follow-up. Forty-seven outpatients with schizophrenia completed a 24-week supervised exercise program twice a week, of whom forty-six were assessed after the follow-up period. Demographic and clinical measures were collected. Physical health was evaluated using anthropometric measures, six minutes walk test, Eurofit and accelerometer. Mental health was evaluated using Rosenberg Self-Esteem scale, Behavioural Exercise Regulations Questionnaire and World Health Organization Quality of Life Scale – Brief Version questionnaires. Participants were assessed at baseline, post-intervention and 12-week follow up. After follow-up, there were significant differences in time, between groups and in time*group in six minutes walk test. Previously observed improvements in functional exercise capacity were lost by 12-week. Flexibility scores were maintained during intervention but worsened significantly by 12-week. On the other hand, participants reported significant improvements in quality of life - physical domain by 12-week. Moderate-to-vigorous physical activity decreased and sedentary behaviour and number of flamingo errors increased but failed to achieve statistical significance. Persons with schizophrenia will lost physical health benefits previously achieved during an outdoor exercise program when supervised exercise cease.
