- Description
- Physical activity is an essential component of a healthy lifestyle, and schools are ideal settings for promoting activity and wellness. Only half of South African children meet global activity recommendations and overweightness and obesity remain a growing challenge. Disadvantaged communities are at even greater risk, as environmental- and socioeconomic challenges further influence children’s health and activity levels. This study investigated the effect of a physical activity intervention on the following health-related physical fitness parameters of primary schoolchildren: cardiorespiratory fitness, upper- and lower body strength, lower body flexibility, and body composition. More specifically the objectives were to describe and compare the intervention and control groups, at baseline, mid- and post intervene. A cluster randomised controlled trial determined the effect of the intervention. Testing was phased in three cross sectional surveys, baseline, mid and post-intervention. The study sample consisted of 157 children, aged 8-12 years, from two primary schools in the township of Motherwell, Port Elizabeth. The physical activity intervention consisted of two intervention periods, each 10-weeks in duration, and included physical education lessons, move-to-music dance classes, in-class physical activity breaks, and physical activity ‘homework’. Furthermore, a low-cost physical activity-friendly school environment was created with play structures, painted games, and the upgrade of sporting facilities and equipment. The intervention was shown to have significant positive effects on the number of laps ran (p < 0.05), indicating cardiorespiratory fitness, and handgrip strength (p < 0.001), an indicator of upper body musculature strength. No significant effects were found for lower body musculature strength (p > 0.05), lower body flexibility (p > 0.05) or body mass index (p > 0.05). Schoolchildren’s level of health-related physical fitness should be regularly assessed, and effective interventions should be implemented and monitored to ensure that children meet recommended activity and fitness standards. Physical education in South African schools is currently compromised, with children having low levels of in-school activity and high levels of sedentary behaviour. The majority of physical activity and health-related physical fitness measures are poor, with even lower scores for girls and children from lower socioeconomic areas. Interventions are thus essential and should focus on extended durations and higher activity intensities in order to achieve health enhancing benefits.
