Calisthenics before exercise can prevent exercise-induced asthma symptoms like reduced maximal expiratory flow rate in children. This simple warm-up helps maintain lung function during physical activity.

Area of Science:

  • Pediatric Pulmonology
  • Sports Medicine
  • Exercise Physiology

Background:

  • Exercise-induced asthma (EIA) is a condition causing breathing difficulties and reduced performance during physical activity.
  • Symptoms include dyspnea, chest pain, cough, and wheezing, typically appearing within 30 minutes of exercise onset.

Purpose of the Study:

  • To investigate the impact of calisthenics as a pre-exercise intervention on maximal expiratory flow rate (MEFR) in asthmatic children.
  • To assess whether a warm-up routine can mitigate EIA-related declines in lung function.

Main Methods:

  • A prospective, observational study involving 60 asthmatic children (ages 6-16) participating in a soccer game.
  • MEFR was measured before the game and after each set, with statistical analysis comparing pre- and post-exercise values.

  • Patients had intermittent or mild asthma, with some also having allergic rhinitis.

    • Main Results:

    • No significant decrease in MEFR was observed in 52 out of 60 patients after exercise.
    • However, eight patients experienced a notable decline in MEFR, dropping to 77% and 83% of baseline after the first and second sets, respectively.
    • The average basal MEFR was 275 L/s, with post-exercise values remaining stable for most participants.

    Conclusions:

    • Pre-exercise calisthenics effectively prevents the diminishment of maximal expiratory flow rate in asthmatic children.
    • This suggests that a structured warm-up routine can be a beneficial strategy for managing EIA and maintaining physical performance in pediatric populations.
