Summary

Introduction: Numerous studies support the practice of different physical exercise modalities as an effective treatment to address the different problems associated with schizophrenia, reporting that they result in significant improvements in patient symptoms and quality of life. Given the lack of studies comparing different types of training in controlled environments, the aim of this proposed study will be to compare the effects of three physical exercise programs (strength, aerobic, and mixed) on the symptoms, body composition, level of physical activity, and health-related quality of life of patients with schizophrenia. Ethics and dissemination: This study was approved by the ethics committees for Biomedical Research at the CEU Cardenal Herrera University of Valencia in Spain (reference number: CEI18/215). Participants will be fully informed of the purpose and procedures of the study, and written informed consent will be obtained from every participant. The results from this study will be published in peer-reviewed journals and presented in scientific conferences.

Detailed description

The aim of this proposed study will be to compare the effects of three physical exercise programs (strength, aerobic, and mixed) on the symptoms, body composition, level of physical activity, and health-related quality of life of patients with schizophrenia. A multicentre, single-blinded (evaluator), randomised, wait-list controlled (ratio 2:2:2:1) trial will be conducted with 105 patients recruited from different psychosocial care centres. The participants will be randomised into three 16-week training groups comprising 48 sessions lasting one hour each, or to the wait-list control group. The training groups will complete aerobic, strength, or mixed (aerobic + strength) training. The participants will be assessed before, immediately after, and 6 months after the end of the intervention. All the patients in the wait-list control group (n = 15) will receive one of the three trainings immediately after the intervention. The study variables will include positive symptomatology, negative symptomatology, and general symptomology (using the Positive and Negative Syndrome Scale) as the primary outcome; as secondary outcome: body composition (by assessing body mass index, body fat mass and waist circumference), physical activity levels (International Physical Activity Questionnaire-Short Form), and quality of life (abbreviated World Health Organization Quality of Life questionnaire).
