EMG Activity of Transversus Abdominis, Multifidus and Co-Contraction Index in Different Phases Amongst Varied Level Archers: A Cross-Sectional Study

Introduction. Core muscle activity is a necessary requirement in most sports. However, its role in archers has not been studied. Therefore, this study sought to determine muscle activity of Transversus abdominis (TA) and Multifidus (MF) and co-contraction index (CCI) using surface electromyography (s EMG) during different phases of shots in archers with different levels of training.
