“…Given present observations and its safety profile based on other studies in high-risk patients tested without complications (Lennon et al, 2012;Speelman et al, 2012;Thorsen et al, 2009), there appears to be no reason why physician attendance is required. In order to guarantee maximal safety, we recommend that the Astrand-Rhyming test is supervised by an experienced clinician (e.g., a mental health physical therapist) and should preferably be conducted in a setting which has medical cardiopulmonary resuscitation training expertise within a near proximity and on the same site location.…”

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.

“…The hip muscle group testing order was randomized at test session 1 (unrestricted randomization, computer random number generator), and the same order was maintained at session 2. The feasibility of the hip muscle RFD‐SF testing protocol was evaluated as testing compliance and the lack of adverse events . The construct validity of hip muscle RFD‐SF was evaluated as the presence of a linear relationship between torque and respective rate of torque development (RTD) for a series of fast isometric contractions performed over a wide range of intensities …”

“…The feasibility of the hip muscle RFD-SF testing protocol was evaluated as testing compliance and the lack of adverse events. 21 The construct validity of hip muscle RFD-SF was evaluated as the presence of a linear relationship between torque and respective rate of torque development (RTD) for a series of fast isometric contractions performed over a wide range of intensities. 13 All assessments were conducted under isometric conditions and consisted of MVC followed by fast contractions, from which torque was recorded by means of an isokinetic dynamometer (Biodex System 4; Biodex Medical Systems, Shirley, New York).…”

2532Purpose-This scientific statement provides an overview of the evidence on physical activity and exercise recommendations for stroke survivors. Evidence suggests that stroke survivors experience physical deconditioning and lead sedentary lifestyles. Therefore, this updated scientific statement serves as an overall guide for practitioners to gain a better understanding of the benefits of physical activity and recommendations for prescribing exercise for stroke survivors across all stages of recovery. Methods-Members of the writing group were appointed by the American Heart Association Stroke Council's Scientific Statement Oversight Committee and the American Heart Association's Manuscript Oversight Committee. The writers used systematic literature reviews, references to published clinical and epidemiology studies, morbidity and mortality reports, clinical and public health guidelines, authoritative statements, personal files, and expert opinion to summarize existing evidence and indicate gaps in current knowledge. Results-Physical inactivity after stroke is highly prevalent. The assessed body of evidence clearly supports the use of exercise training (both aerobic and strength training) for stroke survivors. Exercise training improves functional capacity, the ability to perform activities of daily living, and quality of life, and it reduces the risk for subsequent cardiovascular events. Physical activity goals and exercise prescription for stroke survivors need to be customized for the individual to maximize long-term adherence. Conclusions-The recommendation from this writing group is that physical activity and exercise prescription should be incorporated into the management of stroke survivors. The promotion of physical activity in stroke survivors should emphasize low-to moderate-intensity aerobic activity, muscle-strengthening activity, reduction of sedentary behavior, and risk management for secondary prevention of stroke.
