Özet
Bu çalışmanın amacı genç futbolcularda farklı dinlenme aralıklarında uygulanan tekrarlı
sprintlerin, sprint performansı ve büyüme hormonu (BH), total testosteron (TT), kortizol ve insülin
hormonları üzerine etkilerini araştırmaktı.
Araştırmaya 14-16 yaş aralığında (ortalama yaş: 15,08±0,67 yıl, boy: 1,74±0,09 m, vücut
kütlesi: 61,88±7,92 kg, vücut yağ yüzdesi: %17,35±3,36, yağsız vücut kütlesi: 51,06±6,25 kg) 12
erkek futbolcu katıldı.Deneklere 10 sn ve 30 sn dinlenme aralığında 6x35 m sprint testi 48 saat arayla
2 farklı günde uygulandı.:Ş Tekrarlı sprint süreleri iki kapılı fotosel sistemi ile kaydedildi. Her iki
dinlenme aralığında tekrarlı sprint süreleri ve anaerobik güç çıktıları hesaplandı. Kalp atım hızı
(KAH) ve kan laktatı (LA) test öncesi, test bitiminde, test sonrası 5 ve 15 dk'da, hormon ölçümleri ise
test öncesi, test bitiminde ve testten 1 saat sonra ölçüldü. Kan örneklerinden radioimmünoassay (RİA)
yöntemi ile hormon seviyeleri tespit edildi. İstatistiki analizlerde tekrarlayan ölçümlerde iki yönlü
varyans analizi (ANOVA), ikili karşılaştırmalarda ise Bonferroni düzeltmesi kullanıldı. İstatistiki
analizler SPSS istatistik paket programı (15,0 version) kullanılarak yapıldı.
Tekrarlı sprint süresi üzerinde dinlenme aralığının etkisi anlamlı bulundu 30 sn dinlenme
aralıklı tekrarlı sprint performansı 10 sn dinlenme aralıklı tekrarlı sprint performansına göre daha
yüksekti (p<0,01). Tekrarlı sprint performansında sprint sayısı ve dinlenme aralığı etkileşiminin
anlamlı olduğu bulundu (p<0,01). Tekrarlı sprint testi anaerobik güç çıktıları üzerinde dinlenme
aralığı ve sprint sayısının etkisi anlamlıydı (p<0,05). 30 sn dinlenme aralıklı tekrarlı sprint testindeki
anaerobik güç çıktıları 10 sn dinlenme aralıklı testteki anaerobik güç çıktılarına göre daha yüksekti
(p<0,05), yorgunluk indeksinin ise daha düşük olduğu görüldü (p<0,01). Dinlenme aralığının LA ve
KAH üzerindeki etkisi anlamlı bulunmadı (p>0,05), LA ve KAH üzerinde zaman faktörü etkiliydi
(p<0,05). Büyüme ve insülin hormonu üzerinde dinlenme aralığının etkisi yoktu (p>0,05), bu
hormonlarda zamana bağlı değişim gözlendi (p<0,01). Testosteron hormonu üzerinde hem dinlenme
aralığının hem de zaman faktörünün etkisi anlamlıydı (p<0,05). Kortizol hormonu üzerinde hem
dinlenme aralığının hem de zaman faktörü etkisinin anlamlı olmadığı gözlendi (p>0,05).
Bu çalışmada genç futbolcularda farklı dinlenme aralığının tekrarlı sprint test süreleri ve
anaerobik güç çıktıları üzerinde etkili olduğu, LA ve KAH üzerinde ise etkisinin olmadığı görüldü.
Dinlenme aralığı testosteron hormon düzeyi üzerinde etkiliyken, hem dinlenme aralığının hemde
tekrarlı sprintin kortizol hormon düzeyini değiştirmediği sonucuna varıldı.
The aim of this study was to investigate the effects of repeated sprints applied at different rest intervals on sprint performance, growth hormone (GH), total testosterone (TT), cortisol, and insulin hormones in young football players. Twelve young male soccer players between the ages of 14-16 (mean age: 15,08±0,67 years, height: 1,74±0,09 m, body mass: 61,88±7,92 kg, body fat percentage: 17.35±3,36%, lean body mass: 51,06±6,25 kg) participated in the study. The 6x35 m sprint test with a rest interval of 10 seconds and 30 seconds was applied to the subjects on 2 different days with intervals 48 hours. Repeated sprint times were recorded with a two-door photocell system. Repeated sprint times and anaerobic power outputs were calculated in both rest intervals. Heart rate (HR) and blood lactate (LA) were measured before the test, at the end of the test, at 5 and 15 minutes after the test, and hormone measurements were measured before the test, at the end of the test and 1 hour after the test. Hormone levels were determined from blood samples by radioimmunoassay (IUD) method. A two-way repeated measures analysis of variance (ANOVA) was used for statistical analyses, and Bonferroni correction was used for pairwise comparisons. Statistical analyses were performed using the SPSS statistical package program (15.0 version). There was a significant effect of the rest interval on the repeated sprint time. The 30 sec rest interval repeated sprint performance was higher than the 10 sec rest interval repeated sprint performance (p<0,01). A significant interaction between sprint number and rest interval was found for repeated sprint performance (p<0,01). The effects of rest interval and number of sprints on anaerobic power outputs of repeated sprint test were significant (p<0,05). Anaerobic power output in repeated sprint test with 30 sec rest interval was higher than anaerobic power output in repeated sprint test with 10 sec rest interval (p<0.05), while fatigue index was found to be lower (p<0,01). The effect of the rest interval on LA and HR was not significant (p>0,05), while the effect of time factor was significant on LA and HR (p<0,05). Rest interval had no effect on growth and insulin hormones (p>0,05), and time-dependent changes were observed in these hormones (p<0,01). The effect of both rest interval and time factors was significant on testosterone hormone (p<0,05). It was observed that both the rest interval and the time factor had no significant effect on the cortisol hormone (p>0,05). In this study, it was observed that different rest intervals were effective on repetated sprint test times and anaerobic power outputs, but had no effect on LA and HR in young soccer players. While the rest interval was effective on the testosterone hormone level, it was concluded that both the rest interval and the repeated sprint did not change the cortisol hormone level.
