Elite skiers exhibit near-maximal knee extensor electromyographic (EMG) activity during turns. Alpine skiing involves predominantly slow eccentric muscle actions, particularly in high-speed events, influencing muscle control.

Area of Science:

  • Biomechanics
  • Sports Science
  • Motor Control

Background:

  • Alpine skiing involves complex movements influenced by forces during turns.
  • Understanding muscle activation patterns is crucial for performance and injury prevention.

Purpose of the Study:

  • To investigate the influence of accelerative forces during alpine skiing turns on muscle control.
  • To analyze muscle activation and joint kinematics in elite skiers across different disciplines.

Main Methods:

  • Sixteen elite skiers participated in Super G, Giant Slalom, Slalom, or Freestyle Mogul events.
  • Knee and hip joint angles and electromyographic (EMG) activity of knee extensors were recorded during turns.

Main Results:

  • Knee angles varied significantly across disciplines, with smaller angles in high-speed events (SG

  • Knee angular velocity was slower in high-speed disciplines (SG
  • Near-maximal EMG activity was observed in all disciplines, with a predominance of eccentric muscle actions in SG, GS, and SL, a novel finding.

    • Conclusions:

    • The unique pattern of slow eccentric muscle action dominance in alpine skiing has implications for training.
    • Specific training models should consider the demands of accelerative forces and eccentric muscle contractions in alpine skiing.
