Serratus anterior muscle activation during knee push-up plus exercise performed on static stable, static unstable, and oscillating unstable surfaces in healthy subjects

Shoulder muscle activation during stable and suspended push-ups at different heights in healthy subjects

“…That produces obvious gains in strength and hypertrophy, subsequently neglecting the smaller muscles responsible for stabilization. This biased exercise selection creates joint and muscle imbalances, thus may place participants at-risk for (Kolber, Beekhuizen, Cheng, & Hellman, 2010;Kim, Kwon, Kim, Park, Choung, & Weon, 2014). Traditional and unstable push-ups have been used for years to improve muscle performance/rehabilitation of the of the shoulder musculature (Youdas, Budach, Ellerbusch, Stucky, Wait, & Hollman, 2010).…”

The effect of the push-up plus on shoulder muscle activation while using a sling with a pulley

“…This muscle activation can promote the upward rotation of the scapula to the maximum and reduce the alar scapula phenomenon. Studies on the push-up plus exercise have reported that enhancing muscle activity by stimulating the proprioceptors is more effective when the exercise is combined with sensorimotor control training on an unstable floor15,16,17 ) . In this study, a sling connected to a pulley was added to such an unstable surface, and its effect on the selective activity of SA muscles was examined.…”

The effects of surface condition on abdominal muscle activity during single-legged hold exercise

“…Spine movement occurs in the multi-directions, and abdominal muscles react to multidirectional perturbation for dynamic stabilization of the spine in daily activities (Brown et al, 2006). The devices for multidirectional movement on an oscillating unstable surface were have been recommended to improve balance and abdominal muscle function by in therapeutic program (Kim et al, 2014). Third, an IO muscle contraction increases intra-abdominal pressure, which play key role in maintaining lumbar spine stability because the IO muscle blends with the lateral raphe of the thoracolumbar fascia (Williams et al, 1989).…”
