Comparison of Core Endurance, Strength, Power, Balance and Flexibility in Young Elite Sailors

Abstract

Aim: This study examines and compares the core endurance levels, balance performance, muscle strength, and flexibility among young elite saiflors in different sailing classes. Method: Athletes were randomly selected from the Galatasaray Sailing Club and divided into three groups: windsurfing (n=14), optimist (n=13), and laser class (n=13). Demographic features, body mass index, and dominant side of the body were recorded. Upper extremity strength was assessed using a hand dynamometer, while lower extremity power was evaluated through vertical jump, standing long jump, and single-leg jump tests. Core endurance was evaluated with sit-up, plank, and rotary stability tests. Balance and flexibility were assessed using Y balance, straight leg raise, shoulder flexibility, sit and reach, shoulder elevation, and total body rotation tests. The data from the three groups were analyzed using the Kruskal-Wallis H test, and inter-group comparisons were performed with the Mann-Whitney U test. Results: Significant differences were observed among the groups in the hand grip test for both right and left hands (p<0.001). The laser group displayed the highest mean value. The standing long jump test also showed a significant difference between the groups (p<0.05), with the laser group exhibiting the highest mean value. The single-leg jump test revealed a significant difference among the groups (p<0.05), with the windsurfing group having the highest average. The Y balance test indicated a significant difference among the groups (p<0.05), with the optimist group displaying the highest average values. Conclusion: These findings demonstrate that each sailing class necessitates distinct physical attributes and specific performance parameters, particularly in terms of strength and balance.
