Flexion

shoulder flexion 61% of the variance could be accounted for by the sit-and-reach. A correlation was also found between the modified sit-and-reach test and both the shoulder extension and hip flexion tests. For shoulder extension 33% of the variance was accounted for by the modified sit-and-reach and for hip flexion 22% of the variance was accounted for by the modified sit-and-reach. Table 1.

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 there

the should flexion is the sternocleidmastoid. E. What are the muscles between the ribs called? What do they do? The muscles between the ribs are called Serratus Anterior. They are responsible for protecting, stabilizing and moving the scapula. Exercise 3: Muscles of the Upper Body Data Table 3 – Movement(s) performed by each muscle for Figures 8-10.

two different athletes with very diverse abilities. You can see both the direction of the planted foot and the flexion of the knee in both players. Figure 1.

stretched, the rectus femoris may constrain concurrent hip extension and knee flexion. However, if the rectus femoris were to constrain neither of the two actions, the length of the muscle is established as passively sufficient. The two tests that give answer to whether the rectus femoris muscle is passively sufficient is based upon the comparisons between hip extension with knee flexed vs. extended, and/or knee flexion with hip flexed vs. extended. However, note that either test will provide the

Functions of the muscular system: The muscular system has many functions. There are 5 main functions. Firstly, it allows us to balance via proprio receptors. In terms of balance, not only do you rely on the two sensory organs in your inner ear but also receptors in your muscles and tendons help your body to balance. The receptors in your muscles and tendons are called proprio receptors, these proprio receptors detect how stretched your joints, tendons and muscles are. Secondly it allows movement

major body segments are, abduction, extension, flexion, rotation, adduction, and circumduction. Abduction is the movement of a body part away from the midline, an example of that would be lateral raises using a dumbbell. Another example would be the lateral shuffle. It targets the muscles of the thighs, hips, and buttocks. An extension movement would be the return from flexion and an exercise for this would-be leg extensions. An example of a flexion movement is a hamstring stretch. Rotation is the

fundamental movements of major body segments. They all range in movement to utilize the primary joints of the body. First there is Flexion, which is a decrease of angles between body parts. One primary example of this would be calf raises, which cause dorsiflexion as the ankles push upwards and the toes force down. Second we have extension, which is the opposite of flexion, causing an increase in angles between body parts. The best example exercise for extension would be leg extensions, which causes

Bicycling is a healthy form of recreation that people all over the world participate in to various degrees. As an exercise activity, cycling is recognized as a low impact sport that minimizes the potential for damaged muscles or inflammation and soreness in the joints. That said, it’s important to be aware that cycling involves a repetitive motion, roughly 4000 pedal revolutions per hour for the average recreational cyclist, in the hip, knee and ankle joints during the pedal stroke. Like all repetitive

raises her left arm while simultaneously extending her right hip and knee. The muscle fibers of her anterior deltoid engage and act as the agonist for shoulder flexion while the gluteus maximus engages as the agonist for hip extension. The quadriceps femoris group act as the agonist for knee extension. The antagonists for shoulder flexion are the posterior deltoid, latissimus dorsi, teres major, pectoralis major, and the triceps brachii. The antagonist for her hip extension is the iliopsoas while
