Abstract

Bu çalışmada, instabilite cihazlarında ve sabit zeminde yapılan şınav egzersizi sırasında Pectoralis Majör (PM), Antreior Deltoid (AD) ve Triceps Brachii (TB) kaslarının elektromiyografik aktivasyonlarının belirlenmesi amaçlanmıştır. 18-25 yaş aralığında 25 katılımcı, sabit bir yüzey, her iki taraf da kullanılan top (BOSU), Pilates topu ve Fonksiyonel egzersiz bandı (TRX) üzerinde çapraz geçişli deney tasarımında şınav egzersizi uyguladı. Katılımcılar 2 saniye iniş, 2 saniye çıkış fazı olmak üzere 3 tekrardan oluşan şınav hareketini sırasıyla 4 zeminde uyguladı. Egzersiz sırasında PM, AD ve TB kaslarının amplitüdünü belirlemek için yüzey elektromiyografisi (sEMG) kullanıldı. sEMG genliği, kasların izometrik kasılmaları sırasında en yüksek tepe tork değerini veren maksimum istemli kasılma (MİK) yöntemi kullanılarak normalleştirildi. PM kasında TRX’te sabit zemin ve BOSU’ya göre önemli ölçüde daha yüksek normalize sEMG amplitüdü (%MİK) değerleri tespit edildi. AD kasında Pilates topunda diğer zeminlere göre önemli ölçüde daha düşük %MİK değerleri tespit edildi. TB kasında sabit yüzey ve BOSU’ya kıyasla TRX ve Pilates topunda önemli ölçüde daha yüksek %MİK değerleri tespit edilirken BOSU’da sabit zemine göre daha yüksek değerler tespit edildi. TRX’te şınav PM, AD, TB kasları için daha fazla zorluk isteyen antrenörler için iyi bir seçenek olabilirken; AD kası için şınav egzersizinde pilates topunu tercih etmek doğru olmayabilir.

Comparison of Muscle Activation During Push-Ups Exercise on Stable and Unstable Surfaces

Abstract

In this study, it was aimed to determine the electromyographic activations of Pectoralis Major (PM), Anterior Deltoid (AD), and Triceps Brachii (TB) muscles during push-up exercises performed on instability devices and a stable surface. Twenty-five participants aged 18-25 performed push-ups in an experimental crossover design on a stable surface, both sides utilized ball (BOSU), Pilates ball, and TRX Suspension Trainer (TRX). Participants completed the push-up exercise consisting of 3 repetitions, 2 seconds of descent, and 2 seconds of ascent, on four floors, respectively. Surface electromyography (sEMG) was used to determine the amplitude of the PM, AD, and TB muscles during exercise. The sEMG amplitude was normalized using the maximum voluntary contraction (MİK) method, which gives the highest peak torque value during isometric contractions of the muscles. Significantly higher normalized sEMG amplitude (%MİK) values were detected in the PM muscle compared to the stable surface and BOSU in TRX. In the AD muscle, significantly lower %MİK values were detected on the Swiss Ball compared to the other surfaces. Compared to the stable surface and BOSU in the TB muscle, significantly higher %MİK values were detected in the TRX and Swiss Ball, while higher values were detected in the BOSU than in the stable surface. While TRX can be a good option for trainers who want more challenge for the PM, AD, and TB muscles, It may not be suitable to prefer the Swiss Ball in push-up exercise for AD muscle.
