FARKLI ZEMİNLERDE UYGULANAN BRIDGE-PLANK EGZERSİZLERİNDE UYLUK KAS AKTİVASYONUNUN İNCELENMESİ

Öz

Amaç: Araştırmanın amacı, hem genel vücut kuvvetini geliştirmek hem de yaralanma sonrası süreçte tedaviye katkı sağlaması amacıyla farklı zeminlerde uygulanan sırtüstü köprü ve ters plank egzersizlerindeki hamstring-quadriceps kas aktivasyonlarının incelenmesiydi. Yöntem: Araştırmaya aktif spor yaşantısı olmayan 10 katılımcı (dört erkek ve altı kadın, yaş=26,70±3,02 yıl) dâhil edildi. Randomize olarak sabit ve sabit olmayan zeminlerde bilateral köprü ve bilateral ters plank egzersizleri uygulandı. Araştırmada katılımcıların vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF) ve semitendinosus (SEM) kas aktivasyon seviyeleri incelendi. Egzersiz sırasında meydana gelen kas aktivitesi ile birlikte hamstring (BF+SEM)/ quadriceps (VM+VL) oranı da tespit edildi (H:Q). Sonuçlar: En düşük ko-aktivasyon oranı (en dengeli H:Q aktivasyonu) sabit zemin köprü egzersizinde (5,83±4,04) ve en yüksek ko-aktivasyon oranı (hamstring dominant aktivasyon) sabit zemin plank egzersizinde (8,84±6,60) görüldü. H:Q ko-aktivasyon oranında egzersizler arasında anlamlı farklılık bulunmadı (p>0,05). Egzersiz ve zemin farklılığı açısından hamstring ve quadriceps grubunda plank lehine istatistiksel olarak anlamlı farklılık tespit edildi (p<0,05). Tartışma: Ters plank egzersizi sırtüstü köprüye göre daha yüksek agonist kas aktivasyonuna sahiptir. Bu sebeple, özellikle yüksek ko-aktivasyon oranı gerektiren rehabilitasyon sürecindeki hastalara köprü egzersizinin tavsiye edilebileceği düşünülmektedir. Değişik klinik sorunlarda yapılacak değerlendirmeler yön gösterici olabilir.

AN EXAMINATION OF THIGH MUSCLE ACTIVATIONS IN BRIDGE-PLANK EXERCISES PERFORMED ON DIFFERENT GROUNDS

Abstract

Purpose: The study aimed to examine hamstring-quadriceps muscle activations of the supine bridge and reverse plank exercises that are performed for both improving the overall body strength and contributing to the treatment in the process following an injury on different grounds. Methods: Ten participants (four males and six females, age=26.70±3.02 years) without regular sports habits were included in the study. Bilateral supine bridge and bilateral reverse plank exercises were practiced randomly on stable and unstable grounds. In the study, muscle activation values of vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF) and semitendinosus (SEM) muscles of the participants were examined. Along with the muscle activation that occurred during the exercise, hamstring (BF+SEM)/quadriceps (VM+VL) ratio was also determined (H:Q). Results: The lowest co-activation ratio (most balanced H:Q activation) was observed on stable ground bridge exercise (5.83±4.04), and the largest co-activation ratio (hamstring dominant activation) was observed on stable ground plank exercise (8.84±6.60). No significant difference was found between exercises at H:Q co-activation ratio (p>0.05). A statistically significant difference was found in the quadriceps and hamstring group in terms of exercise and difference ground in favor of plank (p<0.05). Conclusion: Reverse plank exercise has greater agonist muscle activation than the supine bridge. Therefore, it is thought that bridge exercise could be advised in the rehabilitation process that necessitates a high level of balance, especially in co-activation ratio. Further study with various clinical problems may direct the process.
