Zusammenfassung

The purpose of this study was to analyse double poling (DP) regarding biomechanical performance determinants and different strategies. Eleven elite cross-country skiers performed DP at 85% of their maximal DP velocity (V85%) during roller skiing (treadmill; 1° inclination) while pole forces and selected joint angles were recorded. A 2D video evaluation categorised skiers into two different DP strategy groups. Strategy A group showed higher elbow (p < 0.01) and hip flexion angular velocities, smaller minimum elbow, knee and hip angles, higher peak pole force, shorter time to peak pole force and a longer relati.ve recovery time (p < 0.05), variables to which V85% was significantly correlated (p < 0.05). DP strategy A provides an effective model for technique and specific strength training while its physiological economy has to be further investigated.
