A change in lumbar curvature can alter fascicle obliquity, lever arm distance, and the length-tension relationships of the erector spinae (McGill et al 2000, Raschke and Chaffin 1996, Singh et al 2011, Tveit et al 1994).
Stiffness and tone (frequency of muscle oscillations) of the both left and right sides of the lumbar erector spinae (ER) and gluteus medius (GM) muscles were investigated.
Trunk extensors such as the multifidus of the transversospinalis group and erector spinae are often tight due to loads placed on them when bending forward: eccentric loads when flexing forward, isometric loads maintaining a bent-forward posture, and eccentric loads when returning to erect position.
hamstrings, hip extension), posterior adductor magnus (hip extension), gluteus maximus (hip extension), gluteus medius (hip abduction), and erector spinae (trunk extension).
Muscles Target: quadriceps Synergists gluteus maximus, adductor magnus soleus; Dynamic Stabilizers: hamstrings, gastrocnemius; Stabilizers: erector spinae, gluteus medius, gluteus minimus Type: Front squat Dumbbells Instructions Stand with dumbbells grasped to sides.
Back extension: Working the erector spinae muscles of the lower back.
They postulated that this might be because of the contribution of a wide range of muscles including abdominal, psoas, posterior hip group, and erector spinae and the larger excursion during lumbar flexion which challenges muscles more.
Cervical postural muscle load was measured using EMG of the bilateral cervical erector spinae and upper trapezii since they are the major stabilizing muscles of the cervical spine (Szeto et al 2005a to d).
These muscles are joined by the following superficial muscles that play a key role in core strength - Rectus Abdominus, Erector Spinae and External Oblique.
EMG was analyzed on the rectus abdominus, external obliques, latissimus dorsi and erector spinae.
The core encompasses the abdominal, oblique, erector spinae and latissimus dorsi muscles (front, sides and back of your trunk).
The gluteal muscles, the quadriceps, calves, anterior deltoids of the shoulders, and erector spinae are the most important drive phase muscles for acceleration.
