This research study investigated the relationship between upper limb isokinetic muscle strength and performance in cross-country sit-skiing. Researchers measured the isokinetic strength of shoulder and elbow extensors in female participants, then correlated this data with performance on a sit-skiing ergometer. Shoulder extension strength, specifically at 60°/s, was found to be a significant predictor of performance in both short and longer duration tests. The study suggests that isokinetic muscle strength testing could be valuable for training Paralympic sit-skiers, although limitations included a small sample size of non-disabled participants. The findings highlight the importance of upper limb strength, particularly shoulder strength, for optimal performance in this sport.
