“…However, most of the therapeutic exercises can activate AM at a high (41-60%MVIC) to a very high (>60%MVIC) level. Han-i Ko and colleagues found that AM can be strengthened from 44±26.5% MVIC to 86.2±46.9% MVIC in active prone hip extension with hip adduction or abduction [24]. Another study evaluated the EMG of AM in six clinical examination tests.…”

Background: Most therapeutic exercises can activate the adductor magnus (AM) at a high to a very high level. It is necessary to find an exercise that can facilitate AM at low to moderate levels in the early stage of sports rehabilitation. This study is aimed to investigate changes in AM activation with various knee kinetic positions during bilateral bridging exercise (BBE) and unilateral bridging exercise (UBE).Method: 20 adults (7 males and 13 females, aged 20-30) volunteered for this study. Surface electromyography (EMG) signals were recorded from AM at four knee flexion angles: 45°, 60°, 90°, and 120° when performing UBE and BBE. The obtained raw data were normalized by the corresponding muscle's maximal voluntary isometric contraction (MVIC). Results: AM recruitment levels were 15.0±8.5% MVIC in BBE and 35.1±21.6% MVIC in UBE. There was no significant difference in the EMG amplitude of AM activity among various knee flexion angles during both UBE and BBE. Conclusions: BBE and UBE can be utilized as therapeutic exercises to facilitate AM from low to moderate intensity at partly weight-bearing positions.

“…Its most important role is in hip extension. Weakness of GM increases the stress on the intervertebral disc and lumbar spine ligaments [6,14,15]. Trunk and lumbo-pelvic exercises instantaneously increase the activities of erector spinae (ES) and hamstring muscles to compensate for the hip extension movement [5,9,16].…”

“…Also, previous studies have found significant differences in muscle activities between prone hip extension (PHE) and PHE-adduction and PHE-abduction exercises. The PHE-abduction position more increases the GM muscle activity than PHE [14]. Additionally, Jeon et al [20] measured the activities of ES, GM, biceps femoris (BF), and semitendinosus (ST) muscles during three hip extension exercises.…”

Exercise Hip Paraspinal muscles PelvisBackground: The gluteus maximus (GM) muscle comprise the lumbo-pelvic complex and is an important stabilizing muscle during leg extension. In patients with low back pain (LBP) with weakness of the GM, spine leads to compensatory muscle activities such as instantaneous increase of the erector spinae (ES) muscle activity. Four-point kneeling arm and leg lift (FKALL) is most common types of lumbopelvic and GM muscles strengthening exercise. We assumed that altered hip position during FKALL may increase thoraco-lumbar stabilizer like GM activity more effectively method. Objects:The purpose of this study was investigated that effects of the three exercise postures on the right-sided GM, internal oblique (IO), external oblique (EO), and multifidus (MF) muscle activities and pelvic kinematic during FKALL.Methods: Twenty eight healthy individuals participated in this study. The exercises were performed three conditions of FKALL (pure FKALL, FKALL with 120° hip flexion of the supporting leg, FKALL with 30° hip abduction of the lifted leg). Participants performed FKALL exercises three times each condition, and motion sensor used to measure pelvic tilt and rotation angle.Results: This study demonstrated that no significant change in pelvic angle during hip movement in the FKALL (p > 0.05). However, the MF and GM muscle activities in FKALL with hip flexion and hip abduction is greater than pure FKALL position (p < 0.001). Conclusion:Our finding suggests that change the posture of the hip joint to facilitate GM muscle activation during trunk stabilization exercises such as the FKALL.
