,166+ CPM). Accelerometer data were downloaded with ActiLife 6 software (ActiGraph LLC, Pensacola, FL) and were included in the analysis if they wore a minimum of four consecutive days, with at least 8 hr of wear time per day. The moderate-to-vigorous physical activity (MVPA) scores were computed as the sum

moderate to vigorous physical activity and take fewer steps per day, compared with healthy individuals. 1 Significant reductions in physical activity are a powerful indicator of cardiovascular disease. Accordingly, those with a history of ACL injury may be at an increased risk of cardiovascular disease

This study compared physical education and recess physical activity levels of elementary school age students with mild mental retardation (MR) and students without disabilities who possessed either high or low cardiorespiratory fitness. For this study, the System for Observing Fitness Instructional Time (SOFIT), a measure of physical activity, was validated for students with mild MR. A significant difference for moderate to vigorous physical activity was obtained between settings. Findings suggest that students with MR and those without disabilities were more active during recess than during physical education. Students with mild MR and those with low cardiorespiratory fitness performed similarly in both the physical education and recess settings.

This study compared moderate-to-vigorous physical activity (MVPA) of students with autism spectrum disorders (ASD) and students without disabilities during inclusive physical education and recess. Students (7–12 years) wore a uniaxial accelerometer in school for 5 consecutive school days. Results indicated a significant difference between settings, F(1,46) = 15.94,p < .01, partial eta2 = 0.26, observed power = 0.97. Students with and without ASD spent a higher proportion of time in MVPA during physical education than during recess, relative to the amount of time spent in those settings. In addition, structured physical education offers opportunities to increase students’ MVPA engagement.

We examined the relationship among objective measures of body composition, lower extremity strength, physical activity, and walking performance and determined whether this interaction differed according to walking ability. Participants were 126 adults ages 60–91 yr. Stepwise multiple regression analysis showed that the 30-s chair stand test (30sCST), appendicular lean mass index (aLMI), body mass index, and age were independent contributors to walking performance, explaining 44.3% of the variance. For slower walkers, appendicular fat mass index (aFMI), moderate to vigorous physical activity (MVPA), 30sCST, and aLMI (r 2 = .49, p < .001) largely explained variance in walking performance. For faster walkers, aFMI and aLMI explained 31.4% (p < .001) of the variance. These data suggest that both fat and lean mass are associated with walking performance in higher- and lower-functioning older adults, whereas MPVA and muscle strength influence walking ability only among lower-functioning older adults.

The purpose was to compare two conditions (leader-plus-video, video-only) that involved different levels of support on facilitating engagement in moderate to vigorous physical activity (MVPA) in adults with mental retardation (MR). Engagement was examined during 10-min aerobic dance sessions conducted 3 days per week over a 10-week experimental period followed by a 4-week maintenance period. The experimental design was single subject reversal (B-A-B-A). Participants were 17 adults (mean age = 42.6 years) with MR (5 females, 12 males) employed at a sheltered workshop. Visual analysis of graphed data revealed no meaningful difference between leader-plus-video and video-only conditions on MVPA engagement. Over 75% of the participants chose to attend each session over the 10-week experiment. Approximately 60% chose to attend during the 4-week maintenance period. Persons who attended, however, did not necessarily engage in MVPA.

The purpose of this study was to compare daily, physical education, recess, and after school moderate to vigorous physical activity (MVPA) levels between children with and without autistic spectrum disorders (ASD). Children ages 5 to 12 years wore a uniaxial accelerometer for five days (four weekdays, one weekend day). There were no differences between children with and without ASD at any physical activity setting. Both groups were more active during recess compared to after school, and children with ASD were similarly active in recess and physical education. Although many children with ASD acquired 60 min of physical education per day, this may decrease with age as opportunities for recess and physical education are eliminated.

Our pilot study investigated if children with Down syndrome engaged in the recommended 60 min of moderate to vigorous physical activity (MVPA) every day. Twenty-three children with Down syndrome (7 girls, 16 boys; mean age 11.7 years, SD = 3.1) wore a triaxial accelerometer for 7 consecutive days to measure their activity levels. The average daily MVPA undertaken was 104.5 min (SD = 35.3 min). Only 8 of 19 children (42.1%) completed at least 60 min of MVPA each day. Lower amounts of activity were associated with older children (r = -.67, p < .01). Parents, teachers, and health professionals need to encourage children with Down syndrome to take part in more frequent MVPA.
