Biomechanical Perspectives on Ski Mountaineering: Kinematics and Muscle Activation

Abstract

Smith Serr

Ski mountaineering is a physically demanding sport that requires a combination of endurance, strength, and technical skill. The biomechanics of ski mountaineering, particularly during uphill movement, play a crucial role in performance optimization and injury prevention. Understanding kinematics and muscle activation patterns provides insights into the mechanical demands of the sport and informs training strategies to enhance efficiency and reduce fatigue. The kinematics of uphill ski mountaineering involve complex lower limb movements that differ significantly from other endurance sports such as running or cycling. Skiers must maintain balance while moving uphill on variable terrain, often with different snow conditions that affect the mechanics of each step. Uphill movement typically consists of a diagonal stride, which requires precise coordination between the lower and upper body. The ankle, knee, and hip joints undergo continuous flexion and extension cycles, with particular emphasis on hip extension to generate forward propulsion. The center of mass shifts dynamically with each step, requiring constant neuromuscular adjustments to maintain stability and optimize force application.
