To evaluate the feasibility, acceptability, and efficacy of an after-school team sports program for reducing weight gain in low-income overweight children.
Six-month, 2-arm, parallel-group, pilot randomized controlled trial.
Low-income, racial/ethnic minority community.
Twenty-one children in grades 4 and 5 with a body mass index at or above the 85th percentile.
The treatment intervention consisted of an after-school soccer program. The "active placebo" control intervention consisted of an after-school health education program.
Implementation, acceptability, body mass index, physical activity measured using accelerometers, reported television and other screen time, self-esteem, depressive symptoms, and weight concerns.
All 21 children completed the study. Compared with children receiving health education, children in the soccer group had significant decreases in body mass index z scores at 3 and 6 months and significant increases in total daily, moderate, and vigorous physical activity at 3 months.
An after-school team soccer program for overweight children can be a feasible, acceptable, and efficacious intervention for weight control.
"For example, in a recent review of after-school PA interventions, Pate and O’Neill reported that three of the five randomized controlled trials that had been conducted had reported positive increases in objectively measured PA . Of particular interest is the Stanford Sports to prevent Obesity Trial (SPORT) which reported a ten minute increase in moderate intensity PA after provision of an extracurricular soccer program . Thus, a ten minute per weekday increase in MVPA would represent a marked increase in PA levels and is consistent with successful PA interventions. "
[Show abstract][Hide abstract] ABSTRACT: Many adolescent girls do not engage in sufficient physical activity (PA). This study examined the feasibility of conducting a cluster randomized controlled trial (RCT) to evaluate an after-school dance program to increase PA among 11-12 year old girls in Bristol, UK.
Three-arm, cluster RCT. Three secondary schools were assigned to intervention arm. Intervention participants received a 9-week dance program with 2, 90-minute dance classes per week. Participants at 2 control schools received incentives for data collection. Participants at 2 additional control schools received incentives and a delayed dance workshop. Accelerometer data were collected at baseline (time 0), during the last week of the dance program (time 1) and 20 weeks after the start of the study (time 2). Weekly attendance, enjoyment and perceived exertion were assessed in intervention participants. Post-study qualitative work was conducted with intervention participants and personnel.
40.1% of girls provided consent to be in the study. The mean number of girls attending at least one dance session per week ranged from 15.4 to 25.9. There was greater number of participants for whom accelerometer data were collected in control arms. The mean attendance was 13.3 sessions (maximum=18). Perceived exertion ratings indicated that the girls did not find the sessions challenging. The dance teachers reported that the program content would benefit from revisions including less creative task time, a broader range of dance genres and improved behavioral management policies. At time 2, the 95% confidence intervals suggest between 5 and 12 minutes more weekday MVPA in the intervention group compared with the control incentives only group, and between 6 minutes fewer and 1 minute more compared with the control incentives plus workshop group. Between 14 and 24 schools would be required to detect a difference of 10 minutes in mean weekday MVPA between intervention and control groups.
It is possible to recruit 11-12 year old girls to participate in an after-school dance study. An after-school dance intervention has potential to positively affect the PA levels of 11-12 year old girls but an adequately powered RCT is required to test this intervention approach.

"However, this provision never materialized until after the club had ended. Similar to other study findings related to psychosocial constructs (Robinson et al., 2003; Story et al., 2003; Weintraub et al., 2008), no improvement in the cognitive and affective "
[Show abstract][Hide abstract] ABSTRACT: The primary purpose of the study was to determine whether girls in one school receiving nurse counseling plus an after-school physical activity club showed greater improvement in physical activity, cardiovascular fitness, and body composition than girls assigned to an attention control condition in another school (N = 69). Linear regressions controlling for baseline measures showed no statistically significant group differences, but the directionality of differences was consistent with greater intervention group improvement for minutes of moderate to vigorous physical activity/hour (t = 0.95, p = .35), cardiovascular fitness (t = 1.26, p = .22), body mass index (BMI; t = -1.47, p = .15), BMI z score (t = -1.19, p = .24), BMI percentile (t = -0.59, p = .56), percentage body fat (t = -0.86, p = .39), and waist circumference (t = -0.19, p = .85). Findings support testing with a larger sample.

"Second, the results add to the increasing evidence regarding the importance of the after-school hours in youth behavior and health. Higher levels of physical activity have been found in the time period after-school in previous studies [31,32,34], and interventions that have targeted this time period have been successful in increasing physical activity and decreasing overweight in children and adolescents [46-48]. Previous studies have also reported distinct gender differences (boys > girls) in levels of MVPA during the after-school period that were not clearly replicated in our study [31,34]. "
[Show abstract][Hide abstract] ABSTRACT: Studies on parent-child correlations of physical activity have been mixed. Few studies have examined concurrent temporal patterns of physical activity and sedentary behaviors in parents and children using direct measures. The purpose of this study was to examine parent-child activity correlations by gender, day of week, and time of day, using accelerometers - a method for direct assessment of physical activity.
Accelerometers were used to assess physical activity and sedentary time in 45 fathers, 45 mothers and their children (23 boys, 22 girls, mean age 9.9 years) over the course of 4 days (Thursday - Sunday). Participants were instructed to wear accelerometers for 24 hours per day. Data from accelerometers were aggregated into waking hours on weekdays and weekends (6:00 am to midnight) and weekday after-school hours (3:00 - 7:00 pm).
Across the 4 days, the mean minutes per day of moderate-to-vigorous physical activity (MVPA) for fathers was 30.0 (s.d. = 17.3), for mothers was 30.1 (s.d. = 20.1) and for children was 145.47 (s.d. = 51.64). Mothers' and fathers' minutes of MVPA and minutes of sedentary time were positively correlated with child physical activity and sedentary time (all ps < .05, with the exception of mothers' and children's sedentary time on weekdays from 6 am to 12 am). Multivariate linear regression analyses resulted in significant effects between parents and children for MVPA across all time segments. For sedentary activity, significant associations were observed only between father and child on the weekend. Sedentary activity of parents and children were not related for other time segments. Models examining the associations of one or two parents with high levels of MVPA or sedentary time indicated a dose response increase in child activity relative to parent.
Greater parental MVPA was associated with increased child MVPA. In addition, having two parents with higher levels of MVPA was associated with greater levels of activity in children. Sedentary time in children was not as strongly correlated with that of their parents. Findings lend support to the notion that to increase childhood activity levels it may be fruitful to improve physical activity among parents.
