“…It is, however, important to note that significantly more patients were smokers, and both sedentary behaviour and smoking contribute to a poor aerobic fitness (38). Low aerobic fitness is a significant risk factor for metabolic syndrome and CVD (39)(40)(41), and has, therefore, been given more attention in recent years in patients with schizophrenia (42)(43)(44). In a recent study, low aerobic fitness was significantly correlated with metabolic syndrome and metabolic abnormalities in patients with FES (45).…”

“…The studies found lower performance at submaximal heart rates in patients with schizophrenia than in healthy controls and lower maximal performance, performance at given lactate concentrations, and peak oxygen uptake [16][17][18][19][20][21]. A reduced cardiorespiratory fitness is also the finding of the latest meta-analysis [22].…”

The aims were to examine the feasibility of and adaptations to endurance training in persons diagnosed with schizophrenia and to address the question whether the principles and beneficial effects of endurance training established in the healthy population apply also to patients with schizophrenia. In this controlled interventional study, 22 patients with schizophrenia and 22 healthy controls performed a standardized aerobic endurance training on bicycle ergometers over 12 weeks. Another group of 21 patients with schizophrenia played table soccer. Endurance capacity was measured with incremental cycle ergometry before and after the intervention and 3 months later. A specific set of outcome parameters was defined. The training stimuli can be assumed to be similar in both endurance groups. Endurance capacity improved significantly in the endurance groups, but not in the table soccer group. Patients and healthy controls showed comparable adaptations to endurance training, as assessed by physical working capacity and maximal achieved power. Differences were found in changes of performance at a lactate concentration of 3 mmol/l. Endurance training was feasible and effective in both groups. The principles and types of training that are usually applied to healthy controls need to be verified in patients with schizophrenia. Nevertheless, patients benefited from endurance training in terms of improvement of endurance capacity and reduction in the baseline deficit in comparison with healthy controls. Therefore, endurance training should be implemented in future therapy programs. These programs need to pay special attention to the differences between patients with schizophrenia and healthy controls.

“…Using this test, research (Nilsson et al, 2012;Ozbulut et al, 2013) has identified that patients with schizophrenia have a significantly lower aerobic fitness compared with age-and gender matched healthy controls. In order to validate these findings, help capture and reduce the burden of cardiovascular disease in individuals with schizophrenia, and further provide clinical practice a validated submaximal test of aerobic fitness, it is important that the psychometric properties of the Astrand-Rhyming test are considered.…”

Reliability and clinical correlates of the Astrand-Rhyming sub-maximal exercise test in patients with schizophrenia or schizoaffective disorder, Psychiatry Research, http://dx.doi.org/10.1016/j.psychres. 2014.08.049 This is a PDF file of an unedited manuscript that has been accepted for publication.

AbstractCardiovascular fitness is reduced in people with schizophrenia and is related to an increased morbidity and mortality. There is mounting interest in the accurate measurement of cardiovascular fitness in schizophrenia, yet existing measures used in the general population have not been tested on validity and reliability in this high-risk group. Therefore, we examined the reproducibility and feasibility of the Astrand-Rhyming sub-maximal exercise test in patients with schizophrenia or schizoaffective disorder. Secondary aims were to assess minimal detectable changes, practice effects and the presence of clinical symptoms that are associated with cardio-respiratory fitness (expressed as estimated oxygen uptake). From 47 patients with schizophrenia or schizoaffective disorder two trials of the Astrand-Rhyming test, administered within three days, were analysed. The intraclass correlation coefficient for the estimated oxygen uptake between the two tests was 0.92 (95% confidence interval: 0.85 to 0.95). The minimal detectable change was 6.5mlO 2 /min/kg. No practice effect could be detected. A backward regression analysis demonstrated that illness duration, negative symptoms and level of physical activity explained 63.0% of the variance in estimated oxygen uptake. The current study demonstrates that the Astrand-Rhyming test can be recommended for evaluating the aerobic fitness in patients with schizophrenia or schizoaffective disorder.
