Comparison of gluteus maximus and hamstring electromyographic activity and lumbopelvic motion during three different prone hip extension exercises in healthy volunteers

Muscle Recruitment Pattern of The Hamstring Muscles in Hip Extension and Knee Flexion Exercises

“…Previous studies (Guex et al, 2012;Kwon and Lee, 2013;Mohamed et al, 2002;Worrell et al, 2001) have revealed that isometric hip extension and knee flexion forces significantly increase as the FLs of the hamstring muscles are lengthened by flexing the hip joint and/or extending the knee joint. Additionally, some studies have reported that the activation patterns of the hamstring muscles during hip extension or knee flexion vary with the changes in the hip and/or knee joint angles (Jeon et al, 2016;Kwon and Lee, 2013;Lunnen et al, 1981;Onishi et al, 2002;Mohamed et al, 2002), but the results are not consistent. Moreover, the variation in the recruitment pattern of the hamstring muscles with changes in muscle FL has not been fully investigated in dynamic hip extension and knee flexion exercises.…”

Comparison of Prone Hip Extension Exercise and Prone Hip Extension Exercise after Iliopsoas Stretching on Lumbopelvic Control and Gluteus Maximus Activity in Subjects with Short Iliopsoas

“…Various interventions, including the conventional PHE, the modified PHE, the single-limb squat and the double-legged squat have been suggested to increase GM activation in individuals with GM weakness. [8][9][10] In previous study, performing the PHE exercise with constant knee flexion of 90° compared to constant full knee extension could be a better strategy to selectively activate GM muscle with minimal activation of BF and ST. 11 In addition, Kang et al (2013) reported that PHE with knee flexion exercise in the 30° hip abduction can lead to maximal GM and minimal hamstring activity than 0° hip abduction position. For these reasons, PHE exercise was performed with 30° hip abduction with 90° knee flexion to increase the activity of GM.…”

“…For these reasons, PHE exercise was performed with 30° hip abduction with 90° knee flexion to increase the activity of GM. 9,11 Iliopsoas stretching might be used to reduce muscle imbalance before exercises to activate GM muscle activity for subjects with a short iliopsoas. Even if this technique might be helpful, no studies have investigated to increase the flexibility of iliopsoas and the activation of GM muscle in subjects with a short iliopsoas.…”

“…14 Two electrodes were placed parallel to the target muscle fiber each on right ES, bilateral MF, right GM, right BF. 11 For normalization of each muscle contraction, the manual muscle testing positions for MVIC of ES, MF, GM, and BF were performed.…”

The Comparison of the Gluteus Maximus Activity during Various Prone Hip Extension in Subject with Chronic Low Back Pain

“…On the other hand, a previous study reported that increased anterior pelvic tilt was related to the delayed onset timing of the GM activity, and the erector spinae and hamstring muscles showed over-activity during PHE in people with CLBP [13][14][15][16]. Therefore, previous studies examined the effectiveness of various exercises to reduce the delay in GM firing relative to that of the biceps femoris (BF) [17][18][19].…”
