Takım Sporcularında Yorgunluğun Yön Değiştirme Hızı, Yön Değiştirme Açığı ve Reaktif Çeviklik Üzerine Etkisinin Cinsiyete Göre İncelenmesi

Abstract

The aim of this study is to investigate the effect of fatigue on change of direction speed (CODS), change of direction deficit (CODD) and reactive agility (RA) in team sports athletes according to sex. A total of 13 female and 15 male volunteers, aged 18-35 years, who had been training for at least three years and/or had competed for at least one year, participated in the study. Participants were invited to the performance laboratory three times for measurements and testing, with at least 48 hours between each session. Before and after Functional Agility Short-Term Fatigue Protocol, 10-meter linear sprint tests, RA tests or CODS tests were conducted in a randomized order. The Y-Agility track was used for both RA and CODS assessments. For RA, participants changed direction in response to a visual stimulus (light) on the Y-Agility test, whereas for CODS, they changed direction in a planned manner. The normality of all variables was verified using the Kolmogorov-Smirnov Test. Differences between sex were assessed using the Independent Samples t-Test. The effects of Sex x Fatigue on the dependent variables (CODS, RA, CODD) were determined using a 2 (Sex) x 2 (Pre/Post Fatigue) Two-Way Mixed Design ANOVA. Fatigue did not have a significant effect on CODS (p = 0,139). Males exhibited significantly higher CODS than females (p = 0,000). The interaction between Sex x Fatigue on CODS was not significant (p = 0,236). Both fatigue and gender had significant effects on RA (p = 0,014 and p = 0.000, respectively). The Sex x Fatigue interaction for RA was not significant (p = 0,437). Fatigue had a significant effect on CODD (p = 0,000). The effect of sex on CODD was not significantly (p > 0,05). The Sex x Fatigue interaction on CODD was not significant (p = 0.574). The findings of this study indicated that CODS was not affected by fatigue, whereas RA and CODD were influenced by fatigue. The results also demonstrated that CODS and RA differed according to sex, while CODD did not. Furthermore, the changes in CODS, RA, and CODD due to fatigue were similar between sex.
