Look at the elbow joint x-ray. Why is 90° the optimal joint angle for biceps activation? What would happen during flexion/extension?

1. Explain what the differences would be between push and pull exercises. Explain what they are, and give examples.  2. How can you use this format to work all motions of the joints worked?3. Describe the upper body/ lower body split. Explain in detail what considerations must be made when using this type of plan.  4. Why are total body workouts longer for each day's workout? Explain5. Why are there 2 days needed for the total body workouts?  Explain the differencecs6. Which plan do you want to use?  Why?  How will it work for you?

An isometric contraction is used while playing darts to: Group of answer choices stop the elbow joint after the dart is released accelerate the elbow to increase dart velocity extend the elbow and throw the dart  stabilize the scapula of the throwing arm

To do Right ankle plantar flexion in the Sagittal plane, the (name the muscle) would have to lie (A – Where?) relative to the joint, and since it can only (PULL), the fibers would have to run (PERPENDICULAR ) to the (D ) axis to achieve the desired movement. choose from: A. Pick from: Anterior, Posterior, Medial, Lateral, Superior, Inferior B. Write in the word “PULL”    C. Write “perpendicular”  D. Pick from :Anterior - posterior, Superior-inferior or Medio - Lateral

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. Pick from: Anterior, Posterior, Medial, Lateral, Superior, Inferior B. Write in the word “PULL”    C. Write “perpendicular”  D. Pick from :Anterior - posterior, Superior-inferior or Medio - Lateral
