The effect of bridge exercise method on the strength of rectus abdominis muscle and the muscle activity of paraspinal muscles while doing treadmill walking with high heels

Abstract

[Purpose] The purpose of this research is to investigate the effect of the method of bridge exercise on the change of rectus abdominis muscle and the muscle activity of paraspinal muscles while doing treadmill walking with high heels. [Subjects and Methods] The subjects of this research are healthy female students consisting of 10 persons performing bridge exercises in a supine group, 10 persons performing bridge exercises in a prone group, and 10 persons in a control group while in S university in Busan. Bridge exercise in supine position is performed in hook lying position. Bridge exercise in prone position is plank exercise in prostrate position. To measure the strength of rectus abdominis muscle, maintaining times of the posture was used. To measure the muscle activity of paraspinal muscles, EMG (4D-MT & EMD-11, Relive, Korea) was used. [Results] The strength of rectus abdominis muscle of both bridge exercises in the supine group and bridge exercises in the prone group increases significantly after exercise. The muscle activity of paraspinal muscle such as thoracic parts and lumbar parts in bridge exercises in the prone group decreases statistically while walking on a treadmill with high heels. Muscle activity of thoracic parts paraspinal muscle and bridge exercises in the supine group decreased significantly. [Conclusion] According to this study, we noticed that bridge exercise in a prone position is desirable for women who prefer wearing high heels as a back pain prevention exercise method.

The immediate effects of two pilates exercises with and without a foam roller on abdominal muscle activity

“…The results showed that deep abdominal muscles (internal oblique) were more activated than RA, and differences in subjects who practiced Pilates activated core muscles and had better stability than those who had not practiced Pilates before (Lee 2021). Most of the studies exploring the effect of Pilates on abdominal muscles have a focus on deeper muscles (Gibbons & Bird 2019, Kim et al 2011, Escamilla et al 2015, Moon et al 2015, Kang et al 2017, Cho & Jeon 2013 or RA and EO in association with trunk muscles (Park et al 2015, Calatayud et al 2019, Lee et al 2016, Tahan et al 2016, or the use of other tools to assess, such as ultrasound to measure muscle thickness (Gibbons & Bird 2019, Moon et al 2015, Cho & Jeon 2013, Tahan et al 2016 or other unstable surfaces (Escamilla et al 2015, Feldwieser et al 2012, Lee et al 2016. Pereira et al (2017) reported that RA and EO were more activated during the single-leg stretch exercise compared to other Pilates positions, and this change in activation occurred within the first session of Pilates (Pereira et al 2017).…”
