Sporcu ve Sedanter Kadınlarda Yorgunluk Sonrası Denge ve Reaktif Performansın İncelenmesi

Abstract

Bu çalışma, Wingate Anaerobik Güç Testi ile indüklenen yorgunluğun atletik ve sedanter genç kadınlarda dinamik denge ve reaktif çeviklik üzerindeki akut etkilerini incelemiştir. Çalışmaya 18–25 yaş aralığında 32 kadın gönüllü katılmış ve sedanter grup (n = 16; 21.62 ± 1.58 yıl) ile sporcu grup (n = 16; 19.75 ± 1.39 yıl) olmak üzere iki gruba ayrılmıştır. İki gruplu ön test-son test yarı deneysel araştırma deseni kullanılmıştır. Standartlaştırılmış ısınmanın ardından katılımcılara Y-Denge Testi ve Y şeklinde reaktif çeviklik testi ile başlangıç ölçümleri uygulanmıştır. Daha sonra 30 saniyelik Wingate testi ile akut yorgunluk oluşturulmuş ve hemen sonrasında son test ölçümleri alınmıştır. Ayrıca kalp atım hızı yanıtları ve algılanan zorlanma düzeyi de kaydedilmiştir. Reaktif çeviklik performansı, yorgunluk sonrasında hem sedanter grupta (p < 0.001) hem de sporcu grupta (p = 0.038) anlamlı düzeyde kötüleşmiştir. Tekrarlı ölçümler ANOVA sonuçları, zaman (p < 0.001) ve grup (p < 0.001) için anlamlı ana etkiler gösterirken, zaman × grup etkileşimi anlamlı bulunmamıştır (p = 0.977). Buna karşın, dinamik denge performansında hiçbir uzanma yönünde anlamlı değişim gözlenmemiştir (tüm p > 0.05). Kalp atım hızı ve algılanan zorlanma yanıtları genel olarak gruplar arasında benzer bulunmuştur (tüm p > 0.05); ancak tepe kalp atım hızı sporcu grubunda anlamlı olarak daha yüksek saptanmıştır (p = 0.036). Bu bulgular, akut yorgunluğun genç kadınlarda antrenman durumundan bağımsız olarak dinamik dengeden çok reaktif çevikliği olumsuz etkilediğini göstermektedir. Uygulamada, antrenman programlarına yorgunluk altında reaksiyon ve karar verme temelli görevlerin dahil edilmesi, bireylerin spora özgü gereksinimlere daha iyi hazırlanmasına katkı sağlayabilir.

An Investigation of Post-Fatigue Balance and Reactive Performance in Athletic and Sedentary Females

Abstract

This study investigated the acute effects of fatigue induced by the Wingate Anaerobic Power Test on dynamic balance and reactive agility in athletic and seden-tary young women. Thirty-two female volunteers aged 18–25 years were divided into two groups: a sedentary group (n = 16; 21.62 ± 1.58 years) and an athlete group (n = 16; 19.75 ± 1.39 years). A two-group pre-test-post-test quasi-experimental design was employed. Following a standardized warm-up, participants completed baseline as-sessments using the Y-Balance Test and a Y-shaped reactive agility test. Acute fatigue was then induced by a 30-s Wingate test, and post-test measurements were obtained immediately thereafter. Heart rate responses and rating of perceived exertion were al-so recorded. Reactive agility performance deteriorated significantly after fatigue in both the sedentary group (p < 0.001) and the athlete group (p = 0.038). Repea-ted-measures ANOVA revealed significant main effects of time (p < 0.001) and group (p < 0.001), whereas the time × group interaction was not significant (p = 0.977). In contrast, no significant changes were observed in dynamic balance performance in any reach direction (all p > 0.05). Heart rate and perceived exertion responses were gene-rally comparable between groups (all p > 0.05), although peak heart rate was signifi-cantly higher in the athlete group (p = 0.036). These findings indicate that acute fatigue impairs reactive agility more than dynamic balance in young women, regardless of training status. Practically, training programs may incorporate reaction- and deci-sion-based tasks under fatigue to better prepare individuals for sport-specific de-mands.
