Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Summary

This summary is machine-generated.

A community recreation center after-school program significantly increased children's physical activity compared to school-based programs. This low-cost intervention offers a viable option for promoting activity in youth.

Area of Science:

Pediatric Health
Community Interventions
Physical Activity Promotion

Background:

Childhood obesity is a significant public health concern.
After-school programs (ASPs) are potential settings for physical activity interventions.
Comparative effectiveness of different ASP models for physical activity is not well-established.

Purpose of the Study:

To compare the effectiveness of a community recreation center-based ASP with physical activity enhancements against a standard school-based ASP.
To evaluate the impact on children's moderate-vigorous physical activity (MVPA).

Main Methods:

Natural experiment design involving elementary school children.
Accelerometry used to objectively measure physical activity levels.
Longitudinal data collection at baseline, 6, and 12 weeks with high retention (91%).

Main Results:

Children in the community center ASP showed a significantly greater increase in MVPA (14.7 percentage points) by Week 12 (P < .001).
The multiethnic sample had 43% overweight/obesity at baseline.
Cost analysis indicated a modest additional investment ($1.59/child/day) could achieve similar MVPA gains in school-based ASPs.

Conclusions:

An alternative after-school program in a community recreation center, with adult-led physical activities, is associated with higher physical activity levels.
This model provides a cost-effective strategy for enhancing physical activity in children.
Findings support the integration of enhanced physical activity components into after-school settings.
