Summary

This study found that active knee extension and flexion in athletes vary by sport. Women showed higher knee extension, linked to swimming and gymnastics, while knee flexion related to basketball, age, and other sports.

Area of Science:

  • Sports Medicine
  • Biomechanics
  • Kinesiology

Background:

  • Understanding knee joint mobility is crucial for athletic performance and injury prevention.
  • Athletic activities impose unique demands on the knee, potentially leading to sport-specific adaptations.

Purpose of the Study:

  • To measure active knee flexion and extension in a cohort of athletes.
  • To explore the relationship between these knee movements and various sports activities.

Main Methods:

  • Evaluated active knee extension and flexion in 339 athletes.
  • Analyzed associations between knee movement parameters and sport participation, training hours, age, and sex.

Main Results:

  • Active knee extension was higher in women and positively correlated with swimming and gymnastics hours.

Related Experiment Videos

  • Active knee flexion was associated with basketball participation, negatively with age, soccer, handball, and swimming hours.

    • Conclusions:

    • Findings suggest that active knee flexion and extension exhibit sport-specific adaptations in athletes.
    • These adaptations may influence training strategies and injury risk assessment across different sports.
