Background:

A cluster randomized controlled trial was conducted to assess the effectiveness of the Active Classrooms intervention, which integrates movement into academic lessons, on the moderate-to-vigorous physical activity levels (MVPA) of primary school children during class-time and throughout the school day.

Methods:

Ten classroom teachers and their students aged 8 to 12 years were recruited and randomized into the Active Classrooms intervention group (n = 131students, n = 5teachers) or a delayed-treatment controlled group (n = 117students, n = 5teachers). The intervention group participated in active academic lessons taught by the classroom teacher over an 8 week period. Accelerometers were used to gather physical activity data at baseline, postintervention and at 4 months follow-up. Teachers completed a questionnaire to evaluate the program.

Results:

A significant difference for change in daily class time MVPA levels was identified between the treatment (n = 95) and control (n = 91) groups from pre- to postintervention (P < .001) and this difference was maintained at follow-up (P < .001). No significant difference emerged between the treatment and control groups for change in school day MVPA levels from pre- to postintervention (P = .52) or follow-up (P = .09). Teachers reported that they were highly satisfied with the program.

Conclusions:

Movement integration has the potential to improve physical activity levels of primary school children in the classroom.

Background:

Physical activity is beneficial in several clinical situations and recommended for patients with ischemic heart disease, as well as for those undergoing cardiac surgery.

Methods:

In a randomized controlled trial, 34 patients underwent coronary artery bypass grafting. A randomized control group (n = 15) submitted to conventional physiotherapy. The intervention group (n = 19) received the same protocol plus additional aerobic exercise with cycle ergometer. Pulmonary function by spirometry, respiratory muscle strength by manovacuometry, and functional capacity through 6-minute walking test was assessed before surgery and at hospital discharge.

Results:

There was significant reduction in pulmonary function in both groups. In both groups, inspiratory muscle strength was maintained while expiratory muscle strength significantly decreased. Functional capacity was maintained in the intervention group (364.5 [324.5 to 428] vs. 348 [300.7 to 413.7] meters, P = .06), but it decreased significantly in control group patients (320 [288.5 to 393.0] vs. 292 [237.0 to 336.0] meters, P = .01). A significant difference in functional capacity was also found in intergroup analyses at hospital discharge (P = .03).

Conclusion:

Aerobic exercise applied early on coronary artery bypass grafting patients may promote maintenance of functional capacity, with no impact on pulmonary function and respiratory muscle strength when compared with conventional physiotherapy.

The purpose of this meta-analysis of randomized trials was to determine the effectiveness of aerobic plus resistance exercise interventions on body composition related to variables in overweight and obese youth. A computerized search was made of 7 databases. The analysis was restricted to randomized controlled trials that examined the effect of aerobic and resistance exercise on body composition (body weight, body mass index, fat mass, fat-free mass, and waist circumference) in obese youth. Two independent reviewers screened studies and extracted data. Weighted mean differences (WMD) and 95% confidence intervals were calculated. Nine studies were selected for meta-analysis as they fulfilled the inclusion criteria (n = 365). Aerobic plus resistance exercise interventions (8–24 weeks duration) produced a decrease in body weight (WMD=-3.31 kg), body mass index (WMD=-1.05 kg/m2), and fat mass (WMD=-1.93% and 5.05 kg), but changes in fatfree mass and waist circumference were not observed. These changes were accentuated through programs of at least 60 min of exercise per session, generating greater reductions in body weight (WMD=-4.11 kg), fat mass (WMD=-4.07%), and increase in fat-free mass (WMD = 2.45 kg). This meta-analysis provides insight into the effectiveness of short-term aerobic plus resistance exercise interventions for decreasing body weight, body mass index, and fat mass in pediatric obesity.
