isometric phase of the movement. And in the downward phase spine extended to create an eccentric contraction which is the -strongest phase- eccentric phase of the movement. 8) Back hyperextension: the primary muscle is erector spinae .during spine extension the primary muscle undergoes concentric contraction. (Concentric phase of movement). (Upward phase).and to hold the erector spinae in the isometric phase of the exercise. While downward phase the spine flexed and the primary muscle undergo an eccentric

The process of doing squats involves a process of using muscles in bottom half of the torso. There are primary muscles in doing squats which are the gluteus maximus, quadriceps, and hamstrings. The gluteus maximus is the largest muscle in the body and covers each buttock. The origin of this muscle is the sacrum, coccyx, and ilium. The insertion is the posterior surface of femur and fascia of the thigh which helps to extend the thigh at the hip. The gluteus maximus helps to straighten the limb at

1. Start in mountain pose. 2. Separate your legs into a wide stance (4-5 feet). Check to ensure your heels are aligned. Take a centering breath. 3. Turn your right foot/toes outward 90 degrees, parallel with the left foot. Now turn your left foot inwards 45 degrees. 4. Lift through the arches of the feet as you bend your front knee so that it is parallel with the earth and the knee bends until it is directly over the right foot. 5. The back leg remains straight, and weight should be through

The act or an instance of connecting one entity to another is the definition of joining. To join something, a person has to have a will or motivation to do so. Whether that motivation is positive or negative does not affect the action of joining. This is vividly exhibited throughout “Leap” as two people are joining hands contrary to the essence of their horrific surroundings during the terrorist attack on 9/11 that caused the World Trade Center to collapse. Within the tragedy surrounding, two people

Introduction One of the identified critical instructional components for helping students learn to read is vocabulary. Since the National Reading Panel (2000) and the National Early Literacy Panel (2009) reported that strong early oral vocabulary knowledge is a predictor for later successful reading outcomes, an increased research and teaching focus in this area has arisen. The achievement gap that is a central concern in education and society today is associated to a “word gap” that begins early

KPE160H1F – FUNDAMENTALS OF HUMAN MOVEMENT ASSIGNMENT #1 1. Theory of Tests of Passive Sufficiency (3 marks) a. In order to test the passive sufficiency of a bi-articular structure, such as a muscle, both joints which that structure crosses must first be identified. Additionally, the movements of those two joints which will constrain that structure must be identified. Next, one joint must be selected, and placed into the position that may constrain the structure. At the same time, the other joint

The players were tested using a ten-camera motion analysis system. Markers were placed on various spots on the body to assess movements at the pelvis, thorax, shoulder, arm, and hand. The markers measure flexion, extension, lateral flexion, and rotation of the trunk. For the upper limb, it measured internal and external rotation. The players performed ten spike trials to various spots on the court. For these trials, were then analyzed and Mitchinson concluded that

A surprising number of problems arise from tight hamstrings and, given the frequency of knee injuries among athletes and dancers, it 's obvious that the methods used to keep them free could be better. This article presents a more effective way to free your hamstrings, improve your performance, and avoid injury. A Look at Your Hamstrings The hamstrings are the muscles that run from behind and below your knees up the backs of your thighs to your "sitbones". Soft tissue injuries, knee pain, torn menisci

stated in Haan et al. (2011), “the AMCL is divided in two functional components and is taut throughout the full range of flexion and extension because the components are alternatively tightening throughout this range of motion. The posterior part of the AMCL is taut from eighty degrees flexion to full flexion; in contrast, the anterior part of the AMCL is taut in extension.” The AMCL is a stronger ligament than the PMCL, acting as the primary medial ligamentous joint stabilizer. The function of the

Thomas Test During the Thomas test, the patient is lying supine (Face up) on the table, the examiner is standing besides the patient. The examiner places one hand between the Lumbar lordotic curve and the table top. One leg is passively flexed to the patient’s chest, allowing the knee to flex during the movement. The opposite leg which is the one being tested rest flat on the table. If the test is positive for hip flexor tightness, the involved leg rises off the table. The structures being implicated
