Influence of muscle activation of posterior oblique sling from changes in activation of gluteus maximus from exercise of prone hip extension of normal adult male and female

Abstract

[Purpose] There have been many study ipsilateral erector spinae in regard of prone hip extension (PHE). However, mediating methods have been focusing on the reinforcement of gluteus. Hereupon, this study is intended to identify how an increase of gluteus maximus influences on posterior oblique sling (POS) and suggest a mediating method to effectively reinforce them. This study shows the seclective POS strength exercise. [Participants and Methods] This study has been conducted on normal male (13) and female (13), and participants were asked to proceed PHE exercise and prone hip extension with hip abduction with knee flexion (PHEAKF). Surface electromyography (EMG) was recorded from the contralateral latissimus dorsi, contralateral erector spinae, ipsilateral erector spinae, ipsilateral gluteus maximus, and ipsilateral biceps femoris. A paried t-test was used to compare muscle activity POS. [Results] EMG activity of the contralateral latissimus dorsi, ipsilateral erector spinae, and ipsilateral gluteus maximus was significantly greater performed PHEAKF than PHE. As for ipsilateral biceps femoris, muscle activation was lower in PHEAKF than PHE. [Conclusions] According to the results of this study, increase in muscular activation from the direction of muscular fiber and posterior oblique sling seems to be an important factor that influencontralateral crector spinae on muscular activation of POS.

Tensile Force Transmission from the Upper Trunk to the Contralateral Lower Leg throughout the Posterior Oblique Sling System

“…This mechanism plays a crucial role in the optimal energy cost [13][14][15][16]. Previous studies showed the relationships between the upper body and gluteus maximus during gait and between the upper body and hamstrings during prone hip extension [23,24,32]. However, whether the upper portion of the POS is connected to the lower leg below the hamstring, including the ankle joint, is yet to be determined.…”

“…The fact that the greatest pain occurred during DF in the sitting position with trunk rotation indicates that the tissue in this position experiences the greatest tautness. Some studies examined the interconnection between the latissimus dorsi and hamstrings by the POS [23,24,32]. However, whether the POS is connected by the terminal end of the extremity has not been examined yet.…”

“…However, most precedent studies focused only on the unilateral lower extremity linking the ankle to the hip joint or the influence of upper body motion in the sagittal plane when including the upper body. Recent studies demonstrated that the latissimus dorsi is connected to the contralateral gluteus maximus through the posterior oblique sling (POS) system, which is distally connected to as far as the hamstring [23][24][25][26]. Anatomically, the hamstring is also linked to the terminal end by passive connective and neural tissues [27,28].…”

Pharmaceutical care and active treatment in patients with osteochondrosis

“…The mobility of m. erector spinae was improved by applying flexion and extension exercises to the spine (Lee et al 2019). The main role in increasing muscle strength was played by the exercises with a large ball, which we included in the complex, and their positive effect was due to the possibility of introducing different degrees of instability (Donatelli and Wooden 2009).…”

“…Cross-training for m. gluteus maximus and m. latissimus dorsi. contributed to improving lumbar stability (Jeong et al 2015;Lee et al 2019).…”
