Farklı Tekniklerle Uygulanan Bara Ayak Çekiş Hareketi Sırasında Kas Aktivasyonunun Karşılaştırılması

Abstract

With the increasing importance of physical fitness in the world, physical activity types such as CrossFit, which includes high-intensity combined movements, have become popular. The aim of this study was to compare the rectus abdominis (RA) muscle activation during the kipping toes-to-bar (KTB) and the strict toes-to-bar (STB) movements. RA muscle activation was measured during the KTB and STB exercises in 12 healthy young men. Participants performed 5 repetitions of both KTB and STB exercises in randomized order. Participants performed both exercises with a 5-minute rest interval. For comparing the RA muscle activity during the KTB and STB paired sample t-test was used. A significant difference was found between the KTB (359.56 ± 160.50 μV) and the STB (415.37 ± 185.63 μV) for RA muscle activation (p<0.05). These findings demonstrated that the difference in RA muscle activity during the STB and KTB movements showcases the importance of the STB movement on the RA that revealed greater motor units’ activation in a non-oscillation position. The study finding emerges that the same exercise can lead to different motor unit activations in the same muscle group, depending on the way the movement is performed.
