Dirençli Yüzme Kuvvetleri ve Serbest Stil Sprint Sonuçlarına İlişkin Regresyon Tabanlı Yaklaşım

Öz

Amaç: Bu çalışma, dirençli yüzme sırasında kuvvet üretiminin 25 metrelik serbest stil sprint performansına katkısını incelemeyi amaçlamıştır. Çalışmaya 22 deneyimli amatör yüzücü katılmıştır (yaş: 22.55 ± 5,14 yıl; boy: 175.58 ± 8,91 cm; vücut ağırlığı: 75.30 ± 19,35 kg). Yöntem: Her bir yüzücünün bireysel sprint zamanı baz alınarak, tam vuruşlu serbest stil, flutter kick (çırpınan tekme) ve kol çekişi yüzme denemeleri için dirençli testler yapılmıştır. Kuvvet verileri Biopac MP150 veri toplama sistemi kullanılarak toplanmış ve hem pik hem de ortalama güç çıktıları analiz edilmiştir. Bulgular: Dirençli serbest stil yüzme sırasında ortalama güç ile sprint hızı arasında güçlü bir pozitif korelasyon (r = 0.78, p ≤ 0.001) olduğunu ortaya koymuştur. Ayrıca, kol çekişi denemelerinden elde edilen ortalama (r = 0.682, p ≤ 0.001) ve pik (r = 0.696, p ≤ 0.001) güç değerleri de anlamlı ilişkiler göstermiştir. Buna karşılık, çırpınan tekme denemelerinden elde edilen güç metrikleri sprint hızına daha az katkı sağlamıştır. Regresyon analizi, dirençli serbest stil yüzme sırasında ortalama gücün 25 metrelik sprint hızındaki varyansın %61,1'ini açıkladığını göstermiştir. Bu bulgular, kısa mesafe yüzme performansında süreklilik gösteren güç çıkışının kritik rolünü vurgulamaktadır. Özellikle, kol hareketlerinin itiş gücünü önemli ölçüde artırarak yüzme hızını doğrudan etkilediği bulunmuştur. Sonuç: Dirençli yüzme antrenman protokollerinin, kısa süreli, yüksek yoğunluklu çabalarla ortalama gücün geliştirilmesine odaklanması gerektiği ortaya çıkmaktadır. Antrenman yüklerinin bireysel sprint zamanlarına göre özelleştirilmesi, antrenman verimliliğini ve performans sonuçlarını daha da iyileştirebilir.

Regression-Based Insights into Resisted Swimming Forces and Freestyle Sprint Outcomes

Öz

Purpose: This study aimed to investigate the contribution of force production during resistance swimming to 25-m freestyle sprint performance. Twenty-two experienced amateur swimmers participated (age: 22.55 ± 5.14 years; height: 175.58 ± 8.91 cm; body weight: 75.30 ± 19.35 kg) in this study. Method: Based on each-athlete’s individual sprint time, resistance-based tests were conducted for full-stroke freestyle, flutter kick, and arm-pull swimming. Force data were collected using the Biopac MP150 data acquisition system, and both peak and mean power outputs were analyzed. Results: The results revealed a strong positive correlation between mean power in resisted freestyle swimming and sprint speed (r = 0.78, p ≤ 0,001). Additionally, mean (r = 0.682, p ≤ 0,001) and peak (r = 0.696, p ≤ 0,001) power values from arm-pull trials also showed significant relationships. In contrast, power metrics derived from flutter kick trials contributed less substantially to sprint speed. Regression analysis indicated that mean power during resisted freestyle swimming explained 61.1% of the variance in 25-m sprint speed. These findings underscore the critical role of sustained power output in short-distance swimming performance. In particular, arm movements were found to significantly enhance propulsion, directly influencing swimming speed. Conclusion: Resistance swimming training protocols should emphasize the development of mean power through short-duration, high-intensity efforts. Tailoring training loads to individual sprint times may further improve training efficiency and performance outcomes.
