Understanding the Relationship Between Eccentric Hamstring Strength and Sprint Speed: The Scientific Secret to Fast Running

Abstract

This study aimed to investigate the impact of eccentric hamstring strength, identified as a significant factor in the risk of hamstring injury, on maximum sprinting speed. Twenty-three football players competing in the Turkish Super League, with an average age of 25.12±3.22, were included in the study. The eccentric hamstring muscle strength of the athletes was measured using the N3 Nordic Hamstring Curl Exercise device. The maximum sprinting speeds of the players were determined by a GPS analyst. It was found that there was no significant relationship between eccentric hamstring strength on both dominant and non-dominant sides and maximum sprinting speed. Similarly, no significant relationship was found between the difference in eccentric hamstring strength between the two sides and maximum sprinting speed values (p>0.05). The study concluded that there is no association between eccentric hamstring muscle strength parameters and maximum sprinting speed in football players. As confirmed in this study, isolated maximum eccentric hamstring muscle strength alone does not appear to be the sole determinant parameter for horizontal force production during sprinting. However, further research is needed in this area.

Eksantrik Hamstring Kuvveti ve Sprint Hızı Arasındaki İlişkiyi Anlamak: Hızlı Koşmanın Bilimsel Sırrı

Abstract

Bu çalışma, hamstring yaralanma riskinde önemli bir faktör olarak tanımlanan eksantrik hamstring kuvvetinin, maksimum hızlı koşu üzerindeki etkisini araştırmayı amaçladı. Türkiye Süper Lig'inde mücadele eden, yaş ortalaması 25.12±3.22 olan 23 futbolcu çalışmaya dahil edildi. Sporcuların eksantrik hamstring kas kuvveti, N3 Nordic Hamstring Curl Egzersiz cihazı kullanılarak ölçüldü. Oyuncuların maksimum koşu hızları, bir GPS analisti tarafından incelenerek belirlendi. Dominant ve nondominant taraf eksantrik hamstring kuvveti ile maksimum koşu hızı arasında anlamlı bir ilişki olmadığı bulundu. Benzer şekilde iki taraf arası eksantrik hamstring kuvvet farkı ile maksimum koşu hızı değerleri arasında da anlamlı bir ilişki olmadığı tespit edildi. (p>0,05). Çalışmanın sonucunda futbolcularda eksantrik hamstring kas kuvvet parametreleri ile maksimum koşu hızı arasında bir ilişki olmadığı bulundu. Bu çalışmada doğrulandığı gibi izole maksimum eksantrik hamstring kas kuvvetinin tek başına sprint sırasında yatay kuvvet üretimi için tek belirleyici parametre olmadığını göstermektedir. Ancak bu konuda yapılacak daha fazla çalışmaya ihtiyaç vardır.
