This study aimed to develop a valid and reliable athlete nutrition knowledge awareness scale. Within the scope of the study, the athlete nutrition knowledge awareness scale was developed, and the R programming language psych package and SPSS 25 were used in data analysis. The study was conducted in 2025 with licenced athletes. Quantitative data collection methods were used within the scope of the study. A pilot application was conducted with 50 athletes. The 22-item five-point Likert-type scale was applied to 135 athletes, and EFA was conducted with the data obtained from the scale. Item-total correlations and factor loadings were examined, and items with a value below 0.40 were removed. As a result of the EFA, a two-factor structure consisting of 13 items was obtained. The first factor explained 25.114% of the total variance, and the second factor explained 23.751%; the total explained variance was found to be 48.865%. CFA was performed with the scale applied to 131 athletes, and model fit was evaluated with various fit indices (CFI, TLI, RMSEA, GFI, IFI). According to the CFA results, χ²/df = 1.044, RMSEA = .018, CFI = .995, TLI = .994, GFI = .954, SRMR = .071 were found, and the model was determined to have an excellent level of fit with the data. The developed scale consists of 13 items and 2 sub-dimensions named Basic Principles in Athlete Nutrition and Misconceptions in Athlete Nutrition. The internal consistency of the scale was evaluated with Cronbach’s Alpha coefficient. As a result of the analysis of the 13 items in the scale, the alpha value was found to be .772, which indicates that the overall scale has an acceptable internal consistency. The correlation between the factors was determined as .29. To test the assumptions of factor analysis, the Kaiser-Meyer-Olkin (KMO) sample adequacy test and Bartlett’s test of sphericity were applied. The KMO value was found to be .747, indicating that the sample was sufficiently adequate for factor analysis. Bartlett's test of sphericity was found to be significant (p < .001).
Bu çalışma, günümüzde yaygın olarak kullanılan bütünleştirilmiş nöromüskuler ısınma çalışmaları içerisinde Harmoknee, PEP ve dinamik ısınma çalışmaları arasındaki farklılıkların çeviklik, 10 m sprint ve dikey sıçrama performansı üzerindeki genel etkisini araştırmak amacıyla yapılmıştır. Çalışma grubumuzu, yaşları ortalama 16,85 ± 0,36 olan bir mahalli lig basketbol takımında en az 2 yıldır faal olarak basketbol oynayan 12 gönüllü basketbolcu oluşturmuştur. Sporculara iki gün aralıklarla farklı zamanlarda rastgele yöntemle üç farklı ısınma protokolü uygulandı ve ardından çeviklik, 10m sprint ve dikey sıçrama testleri uygulandı. Çalışmamızdan elde edilen veriler ‘’SPSS 22.0’’ programında analiz edildi. Çalışmamızdaki veriler incelendiğinde farklı ısınma protokollerinin çeviklik, 10 m sprint ve dikey sıçrama performans değerleri yönünden istatistiksel olarak anlamlı bir farkın olmadığı görülmektedir (p<0,05). Araştırma sonucunda elde edilen bulgular ve yapılan literatür karşılaştırması sonuçlarına göre, anaerobik güç gereksinimi olan hareketler için araştırmamızda değerlendirdiğimiz her üç ısınma protokolünün de kullanılabilir olduğu söylenebilir..
