Investigation of the Effect of Strength Exercise Program Applied on Unstable Grounds on Limb Symmetry Index After Anterior Cruciate Ligament Surgery of Female Athletes

Abstract

Aim: The aim of this study is to examine the effect of the strength exercise program applied on unstable surfaces after anterior cruciate ligament surgery on limb symmetry index of female athletes.

Methods: Women aged between 18-32 years (n:50) undergoing anterior cruciate ligament (ACL) reconstruction using a hamstring autograft of 121.74±3.15 days ago participated in the study. Participants were divided into two groups as the study group (SG; n=25) who applied strength training program on unstable grounds and the control group (CG) that applied different return to sports programs. Individualized progressive exercises performed on unstable grounds during 12 weeks were applied to the athletes in the study group for a period of 90 days with 48 training sessions while the athletes in the control group will continue their classical rehabilitation programs. Single leg hop (SLH), Single leg Triple hop (STH), Single leg cross-over hop (SCH) and 6m Timed hop (6MT) tests were performed before and after the training program to determine the limb symmetry index (LSI) between the injured (I) and the noninjured (NI) legs of the athletes.

Results: When the pre- and post-test scores of the athletes were compared, a statistically significant improvement was observed in all parameters for both groups (p<0.05). When the improvemental differences of both groups were evaluated; LEFS, SL-A, SL-S, STH-A, STH-S, SCH-A and TOTAL hop scores showed a statistically significant difference in favour of SG (p <0.05).

Conclusion: The strength exercise program, which was applied on unstable ground, has positive effects on both functional field tests and LSI asymmetry in the return to sport phase of athletes who underwent ACL surgery.

Kadın Sporcularda Ön Çapraz Bağ Cerrahisi Sonrası İnstabil Zeminlerde Uygulanan Kuvvet Egzersiz Programının Alt Ekstremite Simetrisi Üzerindeki Etkisinin İncelenmesi

Abstract

Amaç: Bu çalışmanın amacı kadın sporcularda ön çapraz bağ cerrahisi sonrası instabil zeminlerde uygulanan kuvvet egzersiz programının alt ekstremite simetrisi üzerindeki etkisinin incelenmesidir. 

Materyal ve Metot: Çalışmaya 121,74±3,15 gün önce hamstring otogrefti ile ön çapraz bağ (ÖÇB) rekontrüksiyonu geçiren 18-32 yaşları arasında kadın (n:50) rekreatif sporcular katılmıştır. Katılımcılar instabil zeminlerde kuvvet antrenman programı uygulanan çalışma grubu (ÇG; n=25) ve farklı spora dönüş programları uygulayan kontrol grubu (KG; n=25) olarak ikiye ayrılmıştır. Çalışma grubundaki sporculara 12 hafta süresince instabil zeminlerde gerçekleştirilen bireyselleştirilmiş progresif egzersizler 90 gün süresince 48 antrenman oturumu olacak şekilde uygulanmıştır. Kontrol grubunda ki sporcular ise klasik spora dönüş programlarına devam etmişlerdir. Sporcuların ameliyatlı(A) ve sağlam (S) bacağı arasındaki simetri indeksini belirlemek üzere Tek bacak (TB), Tek bacak üçlü (TBÜ), tek bacak çapraz (TBÇ) ve 6 metre zamanlı (6MZ) sıçrama testleri antrenman programı öncesinde ve sonrasında uygulanmıştır. 

Bulgular: ÇG ve KG de yer alan sporcuların grup içi ön- ve son-test değerleri karşılaştırıldığında her iki grupta da tüm parametrelerde istatistiksel olarak anlamlı gelişim görülmüştür (p<0,05). Her iki grubun gelişim farkları değerlendirildiğinde ise; LEFS, TB-A, TB-S, TBÜ-A, TBÜ-S, TBÇ-A ve TOTAL sıçrama skorlarında ÇG lehinde KG sporcularına göre istatistiksel olarak anlamlı farklılık tespit edilmiştir (p<0,05). 

Sonuç: İnstabil zemin de yapılan kuvvet egzersiz programının ÖÇB cerrahisi geçirmiş sporcuların spora dönüş evresinde hem fonksiyonel saha testleri üzerinde hem de LSI asimetrisi üzerinde olumlu etkileri vardır.
