Genç Elit Yelkencilerde Gövde Kas Enduransı, Kuvvet, Güç, Denge ve Esnekliğin Karşılaştırılması

Abstract

Amaç: Çalışma, genç elit yelkencilerde core dayanıklılık seviyeleri, denge performansı, kas kuvveti ve esneklik arasındaki ilişkiyi değerlendirmek amacıyla yapılmıştır. Yöntem: Sporcular Galatasaray yelken kulübünden rastgele seçilmiş ve windsurfing (n=14), optimist (n=13) ve lazer (n=13) yelken sınıfları olmak üzere göre üç gruba ayrılmıştır. Yelkencilerin demografik özellikleri, vücut kitle indeksleri ve dominant tarafları kaydedilmiştir. Üst ekstremite kuvveti, el dinamometresi kullanılarak değerlendirildi, alt ekstremite gücü ise dikey sıçrama, uzun atlama ve tek ayakla sıçrama testleriyle değerlendirildi. Core dayanıklılık değerlendirmesi için mekik, plank ve rotary stabilite testleri uygulanmıştır. Denge ve esneklik değerlendirmesi için Y denge, düz bacak kaldırma, omuz esneklik, otur- uzan, omuz elevasyon ve tüm vücut rotasyon testleri uygulanmıştır. Üç gruptan elde edilen veriler Kruskal-Wallis H testi kullanılarak analiz edildi ve gruplar arası karşılaştırmalar Mann-Whitney U testi ile yapıldı. Bulgular: Yelken sınıfları gruplar arası karşılaştırıldığında hem sağ hem de sol elin ortalama değerleri açısından el kavrama testi sonuçlarında anlamlı bir fark vardır ve en yüksek ortalama değer laser grubundadır (p<0,001). Durarak uzun atlama testi sonuçlarında gruplar arasında anlamlı fark olduğu görülmüştür ve en yüksek ortalama değer laser grubundadır (p<0,001). Tek bacak zıplama testi sonuçlarına göre anlamlı fark vardır ve en yüksek ortalama değer rüzgar sörfü grubundadır (p<0,05). Y dengesi testi sonuçlarına göre hem sağ hem de sol tarafta gruplar arasında anlamlı bir fark vardır ve en yüksek ortalama değer optimist grubundadır (p<0,05). Sonuç: Bu sonuçlar özellikle kuvvet ve denge parametrelerinde, her yelken sınıfının farklı fiziksel özelliklere sahip olduğunu ve spesifik performans parametrelerine ihtiyacı olduğunu göstermektedir.

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.
