When modifying the cross country ski movement, what should you do?

Changing planes of movement is a crucial aspect of modifying the cross country ski movement because it introduces variation in the exercise, which can help target different muscle groups and enhance overall skill development. By altering the plane of movement, you can simulate different skiing conditions or challenges that might be encountered during actual cross country skiing, such as uphill or downhill skiing, which requires different muscle engagements and techniques. This modification promotes a greater range of functional movement patterns, aiding in balance, coordination, and agility, essential components in skiing.

In contrast, simply changing the speed of the movement may not effectively enhance skill or strength, as it might predominantly focus on cardiovascular intensity without addressing the complexity of the skiing action itself. Increasing the range of motion is beneficial for flexibility and strength, but it does not necessarily touch on the critical aspect of movement pattern specificity related to skiing. Reducing arm involvement could potentially limit the engagement of important muscle groups used during cross country skiing and would not aid in the holistic development required for this sport. Thus, changing planes of movement is a comprehensive strategy that includes various benefits aligned with the nature of cross country skiing.
