Summary
Eight weeks of high-intensity running training improved lung function and exercise efficiency in children. This training enhanced resting pulmonary function and led to deeper breathing during exercise for better effectiveness.
Area of Science:
- Pediatric Exercise Physiology
- Pulmonary Function Testing
- Sports Science
Background:
- Prepubescent children's lung function is crucial for respiratory health and athletic performance.
- Understanding the impact of exercise interventions on pediatric pulmonary function is essential for promoting healthy development.
- Short-term training effects on lung function in children are not fully elucidated.
Purpose of the Study:
- To investigate the effects of 8-week high-intensity intermittent running training on resting and exercise lung function in healthy prepubescent children.
- To compare pulmonary function changes between a trained group and a control group.
- To assess the impact of training on exercise ventilatory responses and efficiency.
Main Methods:
- A trained group (TrG) underwent 8 weeks of high-intensity intermittent running training.
- A control group (ContG) did not participate in the training program.
- Pulmonary function tests and an incremental exercise test on a cycle ergometer were performed before and after the training period.
Main Results:
- The trained group showed significant improvements in resting lung function, including forced vital capacity (FVC) and forced expiratory volume in one second.
- Exercise testing revealed enhanced peak oxygen consumption, minute ventilation, and tidal volume in the trained group post-training.
- The trained group exhibited a more efficient ventilatory response during sub-maximal exercise, with reduced deadspace volume relative to tidal volume.
Conclusions:
- Eight weeks of high-intensity intermittent running training effectively enhances resting pulmonary function in prepubescent children.
- The training program leads to improved exercise ventilation, characterized by deeper breaths and increased efficiency.
- This study demonstrates that short-duration, high-intensity running training is beneficial for respiratory adaptations in young children.
