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.

Dünyada fiziksel uygunluğun öneminin artmasıyla birlikte CrossFit gibi yüksek yoğunluklu kombine hareketleri içeren fiziksel aktivite türleri popüler hale gelmiştir. Bu çalışmanın amacı, salınımlı bara ayak çekiş (kipping toes to bar (KTB)) ve salınımsız bara ayak çekiş (strict toes to bar (STB)) hareketleri sırasında rectus abdominis (RA) kas aktivasyonunu karşılaştırmaktır. 12 sağlıklı erkek bireyin RA kas aktivasyonu KTB ve STB sırasında ölçülmüştür. Katılımcılar rastgele sıra ile hem KTB hem de STB egzersizlerini 5 tekrar gerçekleştirmişlerdir. Katılımcılar her iki egzersizi 5 dakikalık dinlenme aralığı ile gerçekleştirmişlerdir. KTB ve STB sırasında elde edilen RA kas aktivasyonlarının karşılaştırılması için eşleştirilmiş örneklem t-testi kullanılmıştır. RA kas aktivasyonu için KTB (359.56 ± 160.50 μV) ve STB (415.37 ± 185.63 μV) arasında anlamlı fark bulunmuştur (p<0.05). Bu çalışmanın bulguları, STB ve KTB hareketleri sırasında RA kas aktivitesindeki farkın, STB hareketinin RA üzerindeki önemini gösterdiğini ve bu da salınımsız bir pozisyonda daha büyük motor ünite aktivasyonunun ortaya çıktığını göstermektedir. Aynı egzersizin, hareketin yapılma biçimine bağlı olarak aynı kas grubunda farklı motor ünite aktivasyonuna yol açabileceği çalışma bulgusu ortaya çıkmaktadır.
