Patients with schizophrenia have impaired muscle force‐generating capacity and functional performance

Patients with schizophrenia have impaired physical health. However, evidence of how skeletal muscle force‐generating capacity (FGC), a key component of functional performance, may contribute to the impairment is scarce. Thus, the aim of this study was to investigate the patient groups’ skeletal muscle FGC and its association with functional performance. Leg‐press FGC was assessed along with a battery of functional performance tests in 48 outpatients (28 men, 34 ± 10 years; 20 women, 36 ± 12 years) with schizophrenia spectrum disorder (ICD‐10, F20‐29), and compared with 48 healthy age‐ and gender‐matched references. Results revealed reduced one‐repetition maximum (1RM) in men (−19%, P
