Özet
Bu çalışmanın amacı, elit yüzücülerde farklı yüzme stilleri ve mesafeler arasındaki kalp atım hızı değişkenliğini (KAHD) incelemek ve yüzme öncesi, sırası ve sonrasındaki KAHD farklılıklarını karşılaştırmaktır. Çalışmaya 14-18 yaş arasında ulusal ve uluslararası seviyede aktif olarak yarışan 23 elit yüzücü gönüllü olarak katılmıştır. Katılımcılar rastgele çaprazlama tasarımı ile çalışma kapsamında değerlendirilmiştir. Katılımcılar, dört farklı yüzme stilinde üç farklı mesafeyi maksimum hızda tamamlamış ve her bir yüzme seansı sonrasında KAHD parametreleri analiz edilmiştir. Stil ve mesafe bazlı bulgular üzerinde zaman alan ve frekans alanı parametreleri incelenmiş ve bu parametrelerin KAHD üzerine etkileri değerlendirilmiştir. Verilerin istatistiksel analizinde stil ve zaman etkileşimi çok yönlü olarak ele alınmış ve parametrik testlerle değerlendirme yapılmıştır. Bulgular, kalp atım hızı (KAH) ve kalp atım aralığı (RR) parametrelerinin stil ve mesafe bazlı farklılıklar gösterdiğini ortaya koymuştur. 50 metre mesafede RR değerlerinde anlamlı bir artış gözlemlenirken (p<0.05), 100 ve 200 metre mesafelerde bu farklılık belirgin olmamıştır. SDNN ve RMSSD gibi zaman alan parametreler, KAHD üzerine farklı stil ve mesafelerin etkisini göstermiş (p<0.05), ancak RMSSD verileri stil ve zaman etkileşiminde anlamlı bulunmamıştır. Frekans alan parametrelerinden VLF ve LF değerleri, 50 ve 200 metre mesafelerde anlamlı bulunurken (p<0.05), 100 metre mesafede anlamlı farklılık saptanmamıştır. HF değerlerinde ise 50 metre mesafede anlamlı bir değişim tespit edilirken (p<0.05), diğer mesafelerde bu etki belirgin olmamıştır. Sonuç olarak, farklı yüzme stilleri ve mesafeler arasında KAHD üzerinde anlamlı farklılıklar bulunmuş, özellikle kısa mesafelerde sempatik aktivitenin baskın hale geldiği gözlemlenmiştir. Uzun mesafelerde parasempatik aktivitenin toparlanma sürecine olumlu katkı sağladığı belirlenmiş olup, stil ve mesafeye bağlı olarak KAHD' nin değişim gösterdiği sonucuna varılmıştır. Bu bulgular, antrenman planlamasında ve toparlanma stratejilerinde dikkate alınması gereken önemli çıkarımlar sunmaktadır.
This study aimed to investigate heart rate variability (HRV) between different swimming styles and distances in elite swimmers and to compare HRV differences before, during, and after swimming. Twenty-three elite swimmers between the ages of 14-18 years who actively compete at national and international levels participated in the study. Participants were evaluated in a randomized crossover design. Participants completed three different distances at maximum speed in four different swimming styles and their HRV parameters were analyzed after each swimming session. Time domain and frequency domain parameters were analyzed on style and distance based findings and the effects of these parameters on HRV were evaluated. In the statistical data analysis, the interaction of style and time was considered multidimensional and evaluated with parametric tests. The findings revealed that heart rate (HR) and heart rate range (RR) parameters differed based on style and distance. At 50 m distance, a significant increase in RR values was observed (p<0.05), while this difference was not significant at 100 and 200 m distances. Time domain parameters such as SDNN and RMSSD showed the effect of different styles and distances on RR (p<0.05), but RMSSD data were not significant in the interaction of style and time. Among the frequency domain parameters, VLF and LF values were significant at distances of 50 and 200 meters (p<0.05), while no significant difference was found at 100 meters. While a significant change was found in HF values at 50 meters (p<0.05), this effect was not significant at other distances. In conclusion, significant differences were found between different swimming styles and distances on HRV, and it was observed that sympathetic activity became dominant, especially at short distances. In long distances, it was determined that parasympathetic activity contributed positively to the recovery process and it was concluded that the HRV changed depending on the style and distance. These findings provide important implications that should be considered in training planning and recovery strategies.
