Abstract This study aimed to estimate parameters of the model in which perseverance of effort and consistency of interest of grit scale are related directly to objectively measured physical activity (PA) and indirectly via PA intention in school students (N = 209) aged 12 to 14 years. The Grit Scale (Duckworth & Quinn, 2009) was ...
Background There is consistent evidence of an association between physical activity and walking performance in persons with multiple sclerosis (MS). To date, this relationship has been predominantly examined in young and middle-aged adults rather than in the rapidly-growing population of older adults with MS who often times have greater walking ...
Objectives This study examined the contribution of sports participation to overall moderate-to-vigorous physical activity (MVPA) among adolescents, and explored potential moderators. Design Cross-sectional observational study using survey and accelerometry data drawn from the NEighbourhood Activity in Youth (NEArbY) study. Methods Adolescents (n = 358) were recruited from secondary schools in Melbourne, Australia. ...
Abstract The purpose of this study was to test hypothesized relationships of the health promotion model (HPM) as a means of predicting moderate‐to‐vigorous physical activity (MVPA) among urban, adolescent girls. A secondary analysis of baseline data from a group randomized controlled trial was conducted. The study involved eight ...
Purpose To examine the prospective associations between spinal pain exposures and risk factors for cardiovascular disease in children and explore the mediating role of health-related physical activity. Methods Students were recruited from ten public primary schools. Each week from November 2008 to October 2010, parents reported spinal pain occurrences in their children ...
Purpose Schools provide opportunities for children to accumulate recommended daily moderate to vigorous physical activity (MVPA). This study aimed to determine physical activity (PA) across the school day among elementary school children in Qatar. Methods This cross-sectional study recruited 181 Grade 1 (5.8 ± 0.4 years) and Grade 4 (9.0 ± 0.5 years) children. Participants wore wrist-based accelerometers for 5 ...
ABSTRACT The study analyzed the effect of number of hours and days of accelerometer use on estimates of physical activity (PA) time in adolescents. Cross-sectional study of 784 adolescents from 10 to 14 years old (53.9% girls). Overlapping 95% confidence intervals (95%CI) were used to compare mean light (LPA), moderate (MPA), vigorous (VPA) and moderate ...
Background Overall time spent in moderate-to-vigorous intensity physical activity (MVPA) and sedentary behavior are both correlated in couples. Knowledge about the nature and psychosocial correlates of such dyadic covariation could inform important avenues for physical activity promotion. Purpose The present study investigates hour-by-hour covariation between partners (i.e., synchrony) in ...
Background To determine if children’s moderate to vigorous physical activity (MVPA) and sedentary time varied across levels of household income in countries at different levels of Human Development Index (HDI), consistent with the theory of epidemiological transition. Methods Data from 6548 children (55% girls) aged 9–11 years from 12 countries at different HDI ...
Objective To parameterize and validate two existing algorithms for identifying out-of-bed time using 24 h hip-worn accelerometer data from older women. Approach Overall, 628 women (80 ± 6 years old) wore ActiGraph GT3X+ accelerometers 24 h d−1 for up to 7 d and concurrently completed sleep-logs. Trained staff used a validated visual analysis protocol to measure ...
