- Brief Summary
The study will compare standard high-intensity training with brief high-intensity training in people with schizophrenia-spectrum or bipolar disorder. The overall aim is to determine which of the two is superior in a long-term perspective.
- Detailed Description
Background: Patients with severe mental disorders (SMD), including schizophrenia spectrum and bipolar disorders, frequently experience suboptimal treatment effectiveness resulting in disabling residual symptoms and cognitive challenges, and have elevated mortality risk amounting to 15-20 years of shortened life expectancy compared to the general population.
Cardiovascular disease (CVD) is a major contributor in this regard. Exercise in general improves cognitive functioning, negative symptoms, quality of life, and reduces the risk of CVD. High intensity training (HIT) has been shown to be feasible for persons with SMD, but attrition and noncompliance are substantial and likely to limit the effectiveness of HIT. A less strenuous HIT could increase adherence to the intervention, which might compensate for a slightly lower efficacy compared to standard HIT. Our study will compare standard 4x4-min HIT to a 4-min single-bout HIT session, as well as explore exercise effects on basic processes in the body. Methods: Patients with schizophrenia spectrum and bipolar disorders are eligible for participation, and those included will be randomized to 26 weeks of either 1) Standard 4 x 4 min HIT at treadmill, or 2) Short 1 x 4 min HIT at treadmill. To reduce dropout, the intervention will usually be delivered in group format, and conducted under the supervision of a physical therapist in collaboration with a postdoctor. The research group has a stable staff with research nurses, biostatisticians and researchers that will secure the dayto- day conductance of the project, including psychometric assessments, drawing of and biobanking of blood, as well as data collection and storing. Measures: Mental and cognitive symptoms, quality of life, motivation, Peak oxygen uptake (V

Group Intervention Description Short HIT High intensity training (HIT) Short 1 x 4 min HIT at treadmill. Starting with 7 min warm-up walking/running, then 1 session with 4 min walking/running at 80-95% of maximal heart rate, ending with 5 min of cooling down. Two sessions per week for 26 weeks. Standard HIT High intensity training (HIT) Standard 4 x 4 min HIT at treadmill. First 7 min warm-up, then 4 sessions with 4 min walking/running at 80-95% of maximal heart rate, with 3 min of active rest in between. Ending with 5 min of cooling down. Two sessions per week for 26 weeks.
