Evaluation Of Dynamic Balance, Functionality And Anthropometric Characteristics In Alpine And Nordic Skiers

Abstract

urpose: The dynamic balance ability, functionality level, and anthropometric structure of elite athletes are closely related to their performance during sports activities. Therefore, this study was designed to evaluate the dynamic balance, functional performance, and anthropometric characteristics of Alpine and Nordic skiers, which are different ski disciplines, and to investigate the relationships between these parameters. Methods: The studywas carried out on licensed Nordic skiers (n=29) and Alpine skiers (n=33). Dynamic balance was evaluated with the Y Balance Test, and functionality was evaluated with the Single Leg Hop for Distance Test. Sitting height and anthropometric measurements of the lower extremities were taken and recorded. Results: The Y Balance Test result for Nordic skiers were higher (p=0.007). The results of the Single Leg Hop for Distance Test were similar in both groups (p=0.534). Lower limb length (p=0.044), thigh length (p=0.005), and leg length (p=0.005) were longer in Nordic skiers. A positive moderate correlation was found between the Y Balance Test and Single Leg Hop for Distance Test in both groups (Alpine skiing r=0.583; p <0.001; Nordic skiing r=0.457; p=0.013). A positive moderate correlation was found between sitting height and dynamic balance (r=0.432; p=0.012) and between leg length and the Single Leg Hop for Distance Test (r=0.442; p=0.010) only in Alpine skiers. Conclusion: In conclusion, this study revealed certain differences regarding the dynamic balance, functional performance, and anthropometric characteristics of Alpine and Nordic skiers and presented guiding results in organizing of training programs for ski disciplines and in the prevention of injuries in ski athletes.
