Exergaming and Aquatic Exercises Affect Lung Function and Weight Loss in Obese Children

Area of Science:

• Pediatric Obesity Research
• Exercise Physiology
• Pulmonary Medicine

Background:

• Childhood obesity is a growing global health concern.
• Obesity negatively impacts lung function and cardiovascular health.
• Effective interventions are needed to manage weight and improve health outcomes in obese children.

Purpose of the Study:

• To investigate the effects of exergames and aquatic exercises on lung function and weight loss in obese children.
• To compare the efficacy of exergames versus aquatic exercises in improving anthropometric variables and pulmonary function.
• To assess the long-term effects of these interventions through a follow-up evaluation.

Main Methods:

• Sixty-one obese male primary-school children were randomized into three groups: video game (exergames), aquatic exercise, and a control group.
• Interventions involved 60-minute sessions, three times per week for the videogame and aquatic exercise groups.
• Lung function (Forced Vital Capacity, Forced Expiratory Volume in 1 second) and anthropometric variables (weight, waist/hip ratio) were measured pre-intervention, post-intervention, and at follow-up.

Main Results:

• Both exergames and aquatic exercises led to significant reductions in body weight compared to the control group.
• The waist/hip ratio index improved significantly in both exercise groups.
• Forced Vital Capacity and Forced Expiratory Volume in 1 second showed significant improvements in the intervention groups compared to the control group, with sustained benefits at follow-up.

Conclusions:

• Exergames and aquatic exercises are effective interventions for promoting weight loss in obese children.
• Both exercise modalities significantly improve lung function in obese children.
• These findings highlight the potential of incorporating exergames and aquatic exercises into childhood obesity management programs.
