ÖZET
 Amaç: Adölesan basketbolcularda akut nöromusküler yorgunluk (NY) durumunun ''drop'' sıçrama (DS) performansına etkisinin incelenmesi dikkate değer görünmektedir. Sunulan çalışmanın amacı; adölesan basketbolcularda tekrarlı ''counter movement'' sıçrama (CMS) modelli oluşturulan NY'nin DS performansına etkisinin incelenmesidir. Gereç ve Yöntemler: Çalışmaya 18 basketbolcu ve 18 sedanter olmak üzere toplam 36 adölesan erkek gönüllü olarak katılmıştır. Katılımcılara 30 saniyelik tekrarlı CMS (TCMS-30) modelli NY öncesi ve hemen sonrası olmak üzere DS testleri uygulanmıştır. DS ve TCMS-30 protokolleri kuvvet platformu kullanılarak gerçekleştirilmiştir. Verilerin analizinde grup farklılıkları (TCMS-30) için bağımsız örneklemler için t-testi; yorgunluk protokolü öncesi ve sonrası (grup içi ve gruplar arası) DS performansındaki değişimin belirlenmesinde ise karışık ölçümlerde ANOVA analizleri kullanılmıştır. Bulgular: Grup içi DS ön ve sontest değerlerinde farklılık tespit edilmiştir (p0,05). Sonuç: Adölesan basketbolculara uygulanan yorgunluk protokolü sonrası DS performansında negatif yönde bir eğilim olsa da bu eğilimin istatistiki olarak önemsiz olduğu ortaya koyulmuştur. Çalışma sonuçları, gelişim çağında ve düzenli egzersiz yapan bireylerde organizmanın zorlayıcı bir egzersize karşı daha hazır olduğunu işaret etmektedir.

ABSTRACT
 Objective: The examination of the effect of acute neuromuscular fatigue (NF) status on drop jump (DJ) performance in adolescent basketball players seems remarkable. The aim of the present study was to examine the effect of NF created with repetitive countermovement jump (CMJ) model on DJ performance in adolescent basketball players. Material and Methods: A total of 36 adolescent voluntarily participated in the study, comprised of 18 male basketball players and 18 male sedentary subjects. The participants performed DS tests before and after an NF created with a 30-second repetitive CMJ model (RCMJ-30). DS and RCMJ-30 protocols were conducted using a force platform. Independent sample t-test was used to investigate group differences (RCMJ-30) and a mixed ANOVA test was performed to establish the change in DJ performance pre and post fatigue protocol (within and between groups) in the data analysis. Results: Statistical differences were detected in the DS pre and post-test values within the group (p0.05). Conclusion: Although there was a negative tendency in DS performance after the fatigue protocol was applied to adolescent basketball players, it was revealed that this tendency was statistically insignificant. The results of the study indicate that the organism is more ready under excessive-load exercise in individuals who are in the developmental age and exercise regularly.
