Summary

Gymnasts experience high elbow compression forces and valgus moments during back handsprings. Greater elbow flexion may protect against these forces, potentially reducing overuse elbow injuries.

Area of Science:

  • Biomechanics
  • Sports Medicine
  • Orthopedics

Background:

  • Overuse injuries to the elbow joint are common in gymnasts.
  • Compression forces and valgus moments at the elbow have been implicated in these injuries.

Purpose of the Study:

  • To analyze ground reaction forces at the hand during the double-arm support phase of a back handspring.
  • To investigate the relationship between elbow joint flexion technique and these forces.
  • To assess the contribution of these forces to elbow joint injury.

Main Methods:

  • Video analysis and force plate analysis were used.
  • Six young female gymnasts were studied during the double-arm support phase of a back handspring.

Main Results:

Related Experiment Videos

  • The elbow joint flexed during the support phase.
  • Large compression forces (2.37x body weight) and valgus moments (0.03x body weight x body height) were generated at the elbow.
  • A correlation was found between elbow flexion and reduced valgus moments.

Conclusions:

  • The combination of high compression forces and valgus moments may lead to lateral elbow injuries like osteochondritis dissecans.
  • Increased elbow flexion during the back handspring support phase may serve as a protective mechanism against excessive valgus moments.
