Christ has both arms drawn a subtle curve, instead of forming a triangle. The loincloth is painted rather small, thus showing the nude body as much as possible. [1] The head shows a narrow halo, as if it came from the figure itself; the face is resting on the chest, showing just enough of his features. [1]
Closed chain exercises are often compound movements, that generally incur compressive forces, while open-chain exercises are often isolation movements that promote more shearing forces. [ 1 ] CKC exercises involve more than one muscle group and joint simultaneously rather than concentrating solely on one, as many OKC exercises do (single-joint ...
These exercises were performed in the supine position on a floor or other flat surface. There were variations, but the primary maneuver is to grab the legs and pull the knees up to the chest and hold them there for several seconds. The patient then relaxes, drops the legs down and repeats the exercise again. [citation needed]
The leg raise is a strength training exercise which targets the iliopsoas (the anterior hip flexors). Because the abdominal muscles are used isometrically to stabilize the body during the motion, leg raises are also often used to strengthen the rectus abdominis muscle and the internal and external oblique muscles.
The painting is known as the Christ of Saint John of the Cross, because its design is based on a drawing by the 16th-century Spanish friar John of the Cross. [1] The composition of Christ is also based on a triangle and circle (the triangle is formed by Christ's arms; the circle is formed by Christ's head).
Open chain exercises are postulated to be advantageous in rehabilitation settings because they can be easily manipulated to selectively target specific muscles, or specific heads of certain muscles, more effectively than their closed chain counterparts, at different phases of contraction.
The straight leg raise is a test that can be performed during a physical examination, with the leg being lifted actively by the patient or passively by the clinician. If the straight leg raise is done actively by the patient, it is a test of functional leg strength, particularly the rectus femoris element of the quadriceps (checking both hip flexion and knee extension strength simultaneously).
Supine and prone decubitus. Recovery position. When lying, the body may assume a great variety of shapes and positions. The following are the basic recognized ones. Supine: lying on the back on the ground with the face up. Prone: lying on the chest with the face down ("lying down" or "going prone"). See also "Prostration".
