    Summary

    Children who practice sports demonstrate superior adaptability to physical exertion. Untrained and overweight children showed similar adaptation, though overweight children had lower maximal oxygen consumption (VO2 max).

    Area of Science:

    • Sports Medicine
    • Pediatric Physiology
    • Exercise Science

    Background:

    • Assessing children's physical adaptability is crucial for understanding their health and athletic potential.
    • Effort tolerance varies significantly based on physical activity levels and body composition.

    Purpose of the Study:

    • To evaluate the adaptability to physical effort in children aged 10-15.
    • To compare the effort adaptation capacity among children with different physical conditions, including those who are overweight.

    Main Methods:

    • Utilized a submaximal triangular test on a bicycle ergometer with a progressive 10 W/min load increase.
    • Monitored heart rate, blood pressure, CO2 production, and O2 consumption.
    • Calculated maximal oxygen consumption (VO2 max) and adaptability coefficient; determined ventilation parameters via spirography.

    Main Results:

    • Children actively engaged in sports exhibited the best adaptability to effort.
    • No significant differences in adaptation were found between untrained and overweight children.
    • Overweight children demonstrated a notably reduced VO2 max (ml/kg/min) compared to others.

    Conclusions:

    • Regular sports participation enhances children's physical effort adaptability.
    • Overweight status in children is associated with reduced cardiorespiratory fitness (VO2 max), even if general effort adaptation appears similar to untrained peers.
