Purpose: This exploratory study tested the feasibility of conducting a novel, personalized exercise intervention based upon the current fitness levels of adolescents with type 1 diabetes (T1DM). The relationships of perceptions of benefits and barriers to exercise, exercise self-efficacy and family support to exercise adherence and changes in cardiovascular (CV) ...
Purpose: The detrimental effects of sedentary time on health may act by replacing time spent in physical activities. The aim of this study was to examine cross-sectional associations between objectively assessed sedentary and physical activity domains on cardiometabolic risk factors using a novel isotemporal substitution paradigm. Methods: Participants were 445 healthy ...
Background: Researchers have recently advocated for the 2-minute walk (2MW) as an alternative for the 6-minute walk (6MW) to assess long distance ambulation in persons with multiple sclerosis (MS). This recommendation has not been based on physiological considerations such as the rate of oxygen consumption (V·O2) over the 6MW ...
Purpose: The purpose of this study is to assess the effects of different strategies of health on the levels of physical activity (PA), physical fitness (PF), cardiovascular disease (CVD) risk factors and quality of life (QoL) of the institutionalized elderly. Concurrently studies were made of the effect of detraining on ...
Background: Lifestyle modification (i.e., weight loss, active lifestyle, healthy diet) is a recommended strategy for the prevention of type 2 diabetes and cardiovascular disease. The purpose of this study was to examine the relationship between receiving a health-care provider's recommendation and adherence to behavioral indicators of adaptation of a healthy ...
Background: Many studies used the older ActiGraph (7164) for physical activity measurement, but this model has been replaced with newer ones (e.g., GT3X+). The assumption that new generation models are more accurate has been questioned, especially for measuring lower intensity levels. The low-frequency extension (LFE) increases the low-intensity sensitivity ...
Abstract: The aims of this study were: to compare energy expenditure (EE) estimated from the existing GT3X accelerometer equations and EE measured with indirect calorimetry; to define new equations for EE estimation with the GT3X in youth, adults and older people; and to define GT3X vector magnitude (...
Purpose: The study aims were to compare raw tri-axial accelerometer output from ActiGraph GT3X + (AG) and GENEActiv (GA) placed on the hip and the wrist and to develop regression equations for estimating energy expenditure. Methods: Thirty children (7-11 yr.) and 30 adults (18-65 yr.) completed eight activities (ranging from lying ...
Background: The minimal physical activity intensity that would confer health benefits among adolescents is unknown. The purpose of this study was to examine the associations of accelerometer-derived light-intensity (split into low and high) physical activity, and moderate- to vigorous-intensity physical activity with cardiometabolic biomarkers in a large population-based sample. Methods: ...
Background: Occupational sedentary behaviour is an important contributor to overall sedentary risk. There is limited evidence for effective workplace interventions to reduce occupational sedentary time and increase light activity during work hours. The purpose of the study was to determine if participatory workplace interventions could reduce total sedentary time, sustained ...
