Reviewer: What Oblique Muscles Do the Dumbbell Side Bends Work? The machine, typically found in gyms, also allows you to adjust the amount of weight and therefore, resistance against your trunk muscles. In detail, a bilateral contraction of the lateral abdominal muscles causes an abdominal press and ventral flexion (internal and external oblique). Changes in the angle of the trunk during STS were analyzed. The movement is brought about by the action on one side of the body of the external and internal oblique muscles, and the quadratus lumborum. When a joint can move forward and backward, such as the neck and trunk, flexion is movement in the anterior direction.

Named for Arthur Saxon, a pioneer in the sport of powerlifting, the Saxon bend is more of a clean-and-jerk motion than a controlled lift.

Unilateral flexion of the trunk would result in ventro-lateral movement of the upper body, that is... bending to one side and toward your toes. Mean trunk flexion during walking was 4.8° in the FW group (range 3.3° to 7.1°) and − 0.2° in the BW group (range 1.5° to −3.7°).

Lateral flexion is made possible by cartilaginous joints between adjacent vertebrae in the spinal column, which unlike most of the bodys movable joints function not as individual units o… Pisa syndrome, also termed lateral trunk flexion (LTF), has been rarely reported in patients affected by Parkinson's disease (PD) and, therefore, the pathophysiology has been poorly investigated. The lateral abdominal muscles comprise the following three muscles: The aponeuroses of the lateral abdominal muscles build the rectus sheath, a tendinous envelope for the rectus abdominis muscle.

From: trunk lateral flexion in The Oxford Dictionary of Sports Science & Medicine ». This exercise requires lateral flexion strength but also internal/external rotation and hip abduction/adduction strength depending on … Exercises to improve lateral flexion A combination of stretching … The lateral abdominal muscles are part of the tension system of the abdominal wall musculature.

In addition, lifting weights on each side can be easier to perform with proper form than deadlifts performed with a barbell. : Taschenlehrbuch Anatomie, 1.Auflage, Thieme Verlag (2010), S.134-138, Abdominal external oblique muscle - Yousun Koh, Abdominal internal oblique muscle - Yousun Koh, Transversus abdominis muscle - Yousun Koh.

The abdominal muscles are responsible for the tension of the anterior body wall. Reading time: 4 minutes. Holding a weighted dumbbell in one hand and standing with feet shoulder-width apart, gradually move into a lean to the side; you will lean to the side of the hand holding the weight. Agonists: Quadratus Lumborum; Synergists: Ipsilateral external oblique and internal oblique, ipsilateral erector spinae, ipsilateral latissimus dorsi; Antagonists: Contralateral quadratus lumborum, contralateral external and internal obliques, contralateral erector spinae, contralateral latissimus dorsi Maura Banar has been a professional writer since 2001 and is a psychotherapist.
