Effects of Static Stretching on Quadriceps Peak Torque and Hip Range of Motion in Professional Soccer Players and Sedentary Subjects

Amaç: Statik germe uzun yıllardır sporcular tarafından egzersiz ve sportif faaliyetler öncesinde yaygın bir şekilde yapılmaktadır. Olası faydaları eklem yerlerinde hareket açıklığındaki artışlara ve/veya kas-tendon birim sertliğindeki azalmalara dayandırılmaktadır. Bu çalışmanın amacı sedanterlerde ve profesyonel futbolcularda statik germenin 60 ve 300°·s-1 hızda konsantrik, izokinetik bacak ekstansiyon pik torku ve kalça hareket açıklığı üzerindeki etkilerini incelemektir. Yöntem: Bu çalışma Ankara Üniversitesi Tıp Fakültesi'nde Haziran 2013 ve Ekim 2014 tarihleri arasında yürütülmüştür. Çalışmaya15 sedanter (21.5 ± 3.7 yaşlarında, vücüt kitlesi 72.6 ± 13.3 kg, boy 177.8 ± 6.6 cm) ve 15 futbolcu (18.7 ± 0.5 yaşlarında, vücut kitlesi 73.7 ± 4.7 kg, boy 181.6 ± 4.2 cm) olmak üzere 30 erkek denek gönüllü olarak katılmıştır. Her iki grubun uyluk ekstansör kas kuvvetleri isokinetik dinamometre ile 60 ve 180 derece hızlarda ve kalça hereket açıklıkları goniometre ile germe yapılmadan ve germe yapıldıktan sonra ölçülmüştür. Sonuçlar: Germe öncesi ve sonrasında; hem futbolcularda, hem de sedanter deneklerde her iki izokinetik hızda kayda değer bir farklılık bulunmamıştır. Ancak, her iki grupta da germe öncesi ile karşılaştırıldığında germe sonrası kalça hareket açıklığının arttığı (p < 0.05) görülmüştür. Tartışma: Otuz saniyelik statik germenin kas performansını etkilemediği ancak esnekliği iyileştirdiği sonucuna ulaşılmıştır. Antrenörlere ısınmanın bir parçası olarak 30 saniyelik germe egzersizleri önerilebilir.

Statik Germenin Profesyonel Futbolcularda ve Sedanterlerde Kuadriseps Pik Tork ve Kalça Hareket Açıklığı Üzerindeki Etkileri

Aim: Static stretching (SS) is commonly performed by athletes prior to exercise and athletic events for many years. Its possible benefits are based on increases in joint Range of Motion (ROM) and/or decreases in muscle-tendon unit stiffness. The purpose of this study was to investigate the effects of static stretching on concentric, isokinetic leg extension peak torque (PT) at 60 and 300°·s-1 and hip range of motion (ROM) in sedentary people and professional soccer players. Methods: This study was performed at Ankara University School of Medicine between June 2013 and October 2014. 30 male subjects; 15 sedentary subjects (aged 21.5 ± 3.7 years, body mass 72.6 ± 13.3 kg, height 177.8 ± 6.6 cm) and 15 soccer players (aged 18.7 ± 0.5 years, body mass 73.7 ± 4.7 kg, height 181.6 ± 4.2 cm) volunteered to participate in this study. Thigh extensor muscle strength was measured by isokinetic dynamometer at speeds of 60 and 180 degrees and hip ROM was measured with goniometer in both groups with and without stretching. Results: There were no significant differences pre- and post- stretching PT; both isokinetic velocities on the soccer players and sedentary subjects. However, ROM increased (p < 0.05) post-stretching compared with pre-stretching in both groups. Conclusion: We concluded that 30 seconds SS can not affect muscular performance but improved flexibility. Thirty second stretching exercises as part of a warm-up to be proposed to the coaches
