D. i. For the following questions, you will perform bicep curl exercises. Begin with your arm at your side and make sure to keep your wrist neutral and your shoulder joint stationary throughout. Break each into the two primary movement phases (lifting, lowering) (What other words could describe these phases?). Indicate the movement occurring at the elbow joint for each and indicate the type of contraction occurring (isometric (1), concentric (C), eccentric (E)). Finally, determine the muscles primarily responsible for causing or controlling these movements (i.e., agonists). Exercise Bicep curl- radioulnar joint supinated Bicep curl- radioulnar joint pronated Lifting phase Movement Contraction Agonist(s) type Su Pint Movement Lowering phase Contraction Agonist(s) type D. ii. Which of the two exercises above (bicep curl with radioulnar joint supinated or pronated) was more difficult? Why is this the case? iii. Next, perform a bicep curl with your radioulnar joint supinated and your wrist flexed. Does it feel easier- harder to complete the exercise? Why is this the case? (Think back to lab 3!)

Describe a physical movement such as sitting, throwing, kicking, stepping up, lifting a coffee cup, etc. Describe the specific muscles involved in this movement using the correct anatomical names. State the type of movement (flexion, extension, and rotation for example) for each muscle that you identify as involved in the movement.
During a Physical Education class, you ask your students to perform a standing vertical jump. Identify the type of muscle contraction involved in the jump and describe the movement patterns of the concentric and eccentric phases. Outline the agonists, antagonists and synergist muscles, which contribute to maximum jump height. Identify the major lower body joints and joint movements, which contribute to the concentric phase of the jump.

A patient demonstrates 0 (absent) DTR of the right triceps brachii, paresthesia over the right third digit and 3/5 strength during resisted elbow extension and wrist flexion testing. What is the most likely diagnosis? What are common types of treatment for this condition?
Poor posture Assume that your client, Phil, age 55, has come to work out with your facility with poor posture. Now - prescribe a few specific stretching and strengthening exercises for this particular area of concern in addition to some aerobic exercise. Assume your client has been cleared for exercise. 1. State the problem your client has. What will this mean as far as special considerations (what sets this apart from the typical exercise prescription) when Phil exercises? 2. State what stretches and/or strengthening/Resistance exercises you will use. Please attach images and state what the name of the exercise is and what it is supposed to stretch/strengthen related to the procedure, or the condition Phil has.
To do Right shoulder abduction – A24 in the frontal plane, the (muscle) would have to lie (A – Where?) relative to the joint, and since it can only (B ), the fibers would have to run (C ) to the (D ) axis to achieve the desired movement. choose from: A.

Seated Mobility: Fitting a Wheelchair You are fitting your patient for a wheelchair. What measurements would you take? What position should the patient be in for measurement? When you measured their upper leg from the popliteal fold (back of the knee) to the back of the hips/chair, the length was 23 inches. To check the measurement, you also measured their lower leg length from their heel to their popliteal fold, and the length was 20 inches. What is the discrepancy? What could be the reason for the discrepancy? What position could you place the patient in to re-take the measurement so that you will not run into this same problem?
