In this phase the athlete is standing in a neutral position holding the ball. The metatarsophalangeal and interphalangeal (great and lesser toes) are held at slight flexion pressed against the ground by an isometric contraction of the flexor halluces longus, flexor digitorum longus, flexor digitorum longus. The ankle is plantar flexed using an isometric contraction of the gastrocnemius and the soleus. The tibiofermoral (knee) joints are slightly flexed by a isomectric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The acetabularfemoral (hip) joint is held at a postion of slight flexion through an isometric contraction of the biceps femoris, pectineus, iliacus, and the psoas. The intervertebral (lumbar) joint is extended by an isometric contraction using the erector spinae. The atlantooccipital (cervical spine) joint is flexed by an isometric contraction erector spinae. Both scapulothroracic (shoulder girdle) joint is protracted by an isometric contraction of the serratus anterior and pectoralis minor. The glenohumeral (shoulder) joint is at internal rotation by an isometric contraction using the pectoralis major, latissimus dorsi, teres major, and the subscapularius. The humeroulnar (elbow) joint is at 90 degrees of flexion by an isometric contraction using the biceps brachii, brachioradialis, and brachialis. The radiocarpal (wrist left and right)

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 must be placed in the position which will NOT put further strain on that structure. The selected joint must then be measured for its range of motion. Next, the same must be done with the selected joint, but in contrast, the other joint must be placed in the position which WILL further constrain the bi-articular structure. Once that has been done, the selected joint’s range of motion must be measured once more.

The tension in the suspenders transfers to the cables which run horizontally between the two far-flung anchorages, through which the tensional forces pass in to the ground and are dissipated. (Bagga 2014).

Introduction During this lab you will become more familiar with the concepts of torque. The purpose of this lab is to determine if the rotational equilibrium condition, Στ = 0, holds experimentally.

Primarily, the function and internal anatomical structure were researched in order to create possible designs and to conclude what key elements needed to be included in the design. In the case of the elbow, it is considered a synovial joint and is further sub-categorized into a hinge or uniplanar joint meaning the joint is responsible for movement in 2 directions in the sagittal plane. Using this information we created two designs, consisting of cotter pins, metal plates and PVC piping.

In 2008, Department of Defense and restructuring of the major combatant commands resulted in a new command, United States Africa Command (U.S. AFRICOM). As a full-spectrum combatant command, AFRICOM is responsible for all U.S. Department of Defense operations, exercises, and security cooperation in the African continent, it’s island nations, and surrounding waters. AFRICOM is part of a diverse interagency team that reflects the talents, expertise, and capabilities within the entire U.S. government. Elements include but are not limited to U.S. Africa (USARAF), U.S. Naval Forces Africa (NAVAF), U.S. Air Force Africa (AFAFRICA), U.S. Marine Corps Forces Africa (MARFORAF), Combined

The forces that are involve with the experiments are basically focused on the concurrent forces. The experiment also allows us to develop the condition of balancing or arranging the angles both sides on a force table. This laboratory experiment allows us to take the mathematical abstraction of a vector to make it tangible as possible. This experiment will look into two ways of

Table 1 & 2: First, find the mass of the wooden block and record the data. Then place the wooden block on the inclined plane (at 0o) with the wide side down. The height of the pulley should be the same height as the screw location on the wooden block. Then hang a weight on the opposite side of the hanger and add weights until block starts to move with a constant velocity (push block to overcome fs¬). Then record the resulted weight of the hanger in Table 1 (as F). Add 500 g to the wooden block and repeat the process. Replace 500 g with 1 kg on the wooden block. Repeat the process described above.

The third design was very similar to the first design but this one was to have a small square of wood attached to the base so it could move more freely. The square was big enough for the two base arms to be about an inch away from each other. This however wouldn’t be good because the entire arm rested on this small square and would break easily and wouldn’t be easy to pivot because of all the weight. The rotation wood shape would need to be bigger. Also the base arm was straight and would restrain the second arm’s movement because it may catch the end of the arms.
