Study Reveals How Poling Camber Angle Influences Power Output in Cross-Country Sit Skiing

A recent study has shed light on how the poling camber angle impacts power output and biomechanical parameters in the double poling (DP) technique used by cross-country sit skiers. This research could potentially influence competition techniques and strength training for athletes participating in this Winter Paralympics sport.

Method and Participants

Twenty-four non-disabled college students took part in the study, performing 30-second maximal effort tests at different poling camber angles on a sit-skiing ergometer. The angles tested were 0, 15, 24, and 30 degrees.

Findings and Implications

The results suggest that while increasing the poling camber angle enhances the DP output power, it reduces efficiency. The power output peaked at 30 degrees, while the cycle time was shortest at 24 degrees. Furthermore, cycle distance and joint range of motions and moments in the shoulder and elbow increased with larger angles. These findings indicate that the optimal poling camber angle may vary depending on the terrain or skiing speed.

Impact on Cross-Country Sit Skiing

Cross-country sit skiing allows athletes with various disabilities to propel themselves using their upper limbs and poles. Key performance determinants in this sport include aerobic capacity, muscle strength, and technical skill, with factors such as pole angle, pacing, and body posture significantly affecting performance. This study's findings could shape technical strategies in competitive sit skiing and influence training programs, leading to improved performance and greater competitive edge for athletes.
