IMPACT OF PERIPHERAL HEART ACTION TRAINING ON FUNCTIONAL CAPACITY IN PEDIATRIC OBESITY

Aim. Childhood obesity represents a major public health challenge, traditionally addressed by specialists in the medical, social, and psychological fields. However, this issue also directly involves professionals in physical education and sport, who play a crucial role in promoting active lifestyles and preventing sedentary behaviors. The aim of the present study was to evaluate the effects of a structured physical activity program on body composition and physical fitness parameters in obese middle school students. Methods. This research sought to contribute to the improvement of quality of life and to the reduction of sedentary behavior among obese students by promoting regular participation in motor activities. The experimental intervention was conducted over a period of approximately six months, from October 2024 to April 2025, in the gymnasium of Lucian Grigorescu Middle School in Medgidia. The study sample consisted of students divided into an experimental group and a control group. Both groups were assessed at baseline and at the end of the intervention using somatic and motor evaluations. The somatic parameters analyzed included height, body mass, and body fat percentage. The experimental group participated in a structured physical activity program, while the control group followed the standard physical education curriculum. Results. Baseline assessments confirmed the comparability of the two groups in terms of somatic and motor characteristics. Following the intervention period, the experimental group demonstrated a statistically significant reduction in body fat percentage at the final assessment compared with baseline values. In contrast, the control group did not show significant changes in this parameter. Conclusions. The findings suggest that the implementation of a structured physical activity program can produce meaningful improvements in body composition among obese school-aged children. Such programs may represent an effective strategy for combating childhood obesity and promoting healthier lifestyles within the school environment.
