From the article abstract:
Purpose: To further the understanding of double poling (DP) through biomechanical analysis of upper and lower body movements during DP in cross-country (XC) skiing at racing speed. Methods: Eleven elite XC skiers performed DP at 85% of their maximal DP velocity (V85%) during roller skiing at 1° inclination on a treadmill. Pole and plantar ground reaction forces, joint angles (elbow, hip, knee, and ankle), cycle characteristics, and electromyography (EMG) of upper and lower body muscles were analyzed.
