Longitudinal influence of musculo-skeletal injuries and extra physical education on physical fitness in schoolchildren

The Effects of Physical Education on Motor Competence in Children and Adolescents: A Systematic Review and Meta-Analysis

Appropriate levels of motor competence are an integrated part of individuals’ health-related fitness, and physical education is proposed as an important context for developing a broad range of motor skills. The aim of the current study was to apply meta-analyses to assess the effectiveness of curriculum-based physical education on the development of the overall motor competence of children and adolescents. Studies were located by searching seven databases and included according to predefined criteria. Random effects models using the standardized effect size (Hedges’ g) were used to aggregate results, including an examination of heterogeneity and inconsistency. The meta-analysis included 20 studies, and a total of 38 effect sizes were calculated. A statistically significant improvement in motor competence following curriculum-based physical education compared to active control groups was observed in children and adolescents (g = −0.69, 95% CI −0.91 to −0.46, n = 23). Participants’ ages, total time for physical education intervention, and type of motor competence assessment did not appear to be statistically significant moderators of effect size. Physical education with various curricula can, therefore, increase overall motor competence in children and adolescents.

Correlation of physical activity and fitness with arches of the foot in children

Study aim: Physical activity is crucial for a child’s development, as well as for the development of the foot. The aim of this study was to assess the correlation of the level of physical activity and physical fitness with the arches of the foot in children in non-weight-bearing and weight-bearing conditions.

Material and methods: The study population consisted of 92 children aged 10 to 14 years. We assessed their physical fitness with a modified Zuchora test. The modification consisted in choosing three (speed, jumping ability, and flexibility) out of a total of six trials. To assess the physical activity, we used a screening test - the anonymous Moderate to Vigorous Physical Activity questionnaire. To analyze the arches of the foot, we used computer equipment based on the Moiré projection method.

Results: Pearson’s chi-squared test did not reveal any significant correlation between physical activity, physical fitness, and longitudinal and transversal arches in children. The percentage of normal and high foot arches increased with increasing levels of physical activity and physical fitness. A Wilcoxon signed-rank test analysis confirmed a statistically significant difference (with p < 0.001) in the longitudinal and transversal arches in measurements in non-weight-bearing and weight-bearing conditions.

Conclusions: 1. In the examined group, there were functional lateral and longitudinal flat feet. 2. A lowered longitudinal arch foot might reduce physical activity and fitness in adolescents.
