Introduction/Lab Description This lab is meant as an introduction to properly instructing individual stretches. (40 points) Objectives 1. Identify the joint movements and muscles being stretched during a variety of stretches. 2. Describe and demonstrate proper technique (e.g. range of motion‚ body positioning‚) for a variety of generally safe and effective stretches to enhance flexibility. 3. Demonstrate the ability to teach common stretches using proper directions‚ cueing‚ and

the subjects for the shoulder flexion‚ shoulder extension‚ hip flexion‚ and hip extension tests. Using the joint as the fulcrum‚ the goniometer was aligned with the axis of rotation of the desired flexibility measurement. The immovable arm of the goniometer was aligned next to the non-moving portion of the body while the moveable arm of the goniometer was aligned with the extending or flexing part of the body. For the shoulder flexion and extension tests‚ the

(n. d) this exercise involves the curling motion where a weight attached to a barbell (ranging from 1.2m to 2.4m) is moved through an arc‚ primarily using the strength of the biceps. The first part of the motion is when the elbows begin in full extension‚ in an overhand grip. The biceps contract to lift the weight upward through an arc‚ to a point where further movement is not possible. The next part of the motion has the elbow joint extending which is called eccentric part. Then‚ the weight is lowered

Ken Lee Gregory Voigt ENS 303 May 9‚ 2013 Tennis Serve Introduction: The tennis serve is one of the most scrutinized athletic motions in all of sports. It is extremely complex and involves many parts that must move in synchronization in order to execute a proper serve. The mechanics of the serve need to be solid because there is a very slim margin for error. When done effectively a serve will have good placement and power to start the point where the server is in an offensive position and

Name: Student Number: Unit: Sports Analysis. Unit Leader: Sally Hope. Date: 31st January 2006. Assignment: ¡®Describe stroke cycle for Breaststroke identifying phases of propulsion and resistance. Define and analyse the major muscle groups used and the energy system demands made on the body in swimming this stroke over 200 metres in 2 minutes 10seconds. Explain how you would develop both muscles and energy systems using appropriate land and water training¡¯. I declare that

To do this the front leg is straightened‚ the movement is knee extension caused by quadriceps and also hamstrings. This causes a build up of torque in the core‚ due to the amount that the shoulder and hip is separated. (FIGURE 7) There is also maximum external rotation in the arm‚ it is in a fully cocked back position

Triple Jump Biomechanics Triple Jump it is where an athlete sprints down a track‚ takes off at the board on one leg‚ hops‚ then again on the same leg before stepping onto the opposite leg and jumping into a pit of sand. This is called “hop‚ step and jump”. To be successful the athlete must be a fast sprinter with strong Gluteus‚ Hamstring‚ Iliopsoas‚ Quadriceps and Vastus muscle groups and core muscles: transverse and rectus abdominus‚ obliques and latissimus dorsi. They must also have the

Muscle and joint actions both affect the performance of a discus-athlete. Various types of joint actions and muscular actions can take place once when the movement is executed by the athlete. As an example‚ a discus-thrower usually activates the horizontal abduction and the horizontal adduction during the preparation or execution phases of his/her throw. The ground contact of the discus-thrower is very important as it keeps the thrower’s center of gravity station within his/her strongest point of

Elbow Joint The elbow joint is a very complex hinge joint located between the distal end of the humerus in the upper region of the proximal ends of the ulna and radius. The elbow joint allows flexion and extension and rotation of the forearm and wrist. The range of motion of the elbow is limited due to the olecranon of the ulna so that elbow can only extend to 180 degrees. Like most synovial joints‚ a thin layer of articulating cartilage covers the ends of the bones to allow smooth movement.

When one is getting ready to throw a pitch‚ there is 5 phase to complete a proper throw. The five phases of a throw are the windup‚ early cocking‚ cocking‚ acceleration‚ and the follow-through. (Hamill & Knutzen)‚ It should be notated that is the wind up phase there is little shoulder activity involved. In the early cocking phase‚ the lead off arm is in a potion of 90 degrees and in a position of abduction and introduces external rotation. As the player transitions into the cocking phase‚ the muscle
