ABDOMINAL BRACING MANEVRASININ FARKLI DİZ FLEKSİYON AÇILARINDA, KUADRİSEPS ZİRVE TORKU, ZİRVE TORKA ULAŞMA SÜRESİ VE KAS AKTİVASYONU ÜZERİNE ETKİSİ

Purpose: The aim of the present study was to investigate effects abdominal bracing maneuver (ABM) on quadriceps peak torque (PT), time (TTPT) and muscle activation levels during maximal strength testing in healthy individuals.
 Methods: Sixteen individuals (Age: 24.63±1.67 years) participated study. Each participant taught ABM technique by a physical therapist’s guidance. Surface electromyography used measure internal oblique/transversus abdominis, vastus medialis, lateralis, rectus femoris levels. Isokinetic dynamometry PT TTPT maximum isometric at 60° 90° knee flexion angles with without ABM. Repeated measures ANOVA performed for statistical analysis.
 Results: There significant angle condition interaction (F(1,15)=5.30, p=0.04). decreased when performed, but decrease greater 600 compared 900 (60°: p=0.001, ES=0.68; 90°: p=0.008, ES=0.33). Quadriceps also (p=0.04) regardless angle.
 Conclusion: revealed that may testing. Researchers should evaluate compensatory movements lumbopelvic region order prevent error force transfer test results.
