Diagonal skiing as a major classical technique has hardly been investigated over the last two decades, although technique and racing velocities have developed substantially. The aims of the present study were to 1) analyse pole and leg kinetics and kinematics during submaximal uphill diagonal roller skiing and 2) identify biomechanical factors related to performance. Twelve elite skiers performed a time to exhaustion (performance) test on a treadmill. Joint kinematics and pole/plantar forces were recorded separately during diagonal roller skiing (98; 11 km/h). Performance was correlated to cycle length (r ¼ 0.77; P , 0.05), relative leg swing (r ¼ 0.71), and gliding time (r ¼ 0.74), hip flexion range of motion (ROM) during swing (r ¼ 0.73) and knee extension ROM during gliding (r ¼ 0.71). Push-off demonstrated performance correlations for impulse of leg force (r ¼ 0.84), relative duration (r ¼ 20.76) and knee flexion (r ¼ 0.73) and extension ROM (r ¼ 0.74). Relative time to peak pole force was associated with performance (r ¼ 0.73). In summary, diagonal roller skiing performance was linked to 1) longer cycle length, 2) greater impulse of force during a shorter push-off with larger flexion/extension ROMs in leg joints, 3) longer leg swing, and 4) later peak pole force, demonstrating the major key characteristics to be emphasised in training.
