anyone have the answers to these question

QUESTIONS

Q1 - Principle of specificity: only the muscles trained will respond.
Provide a concrete example of the principle of specificity to athletics/sports preparation, personal fitness training, or rehabilitation. Choose one exercise and explain why this exercise meets the goal(s) of the program.

Q2 - Degrees of Freedom: the greater the number of joints involved in a movement/exercise the more difficult it is to execute safely and correctly.
a. Explain why the degrees of freedom are true from both an anatomical definition and operation definition (above) perspective.
b. Explain the degrees of freedom mean to working with novice exercisers? In other words, would it be appropriate to start a new exerciser with alternating walking lunges with overhead presses? Why or why not?
 
Q3 - Overload Principle: you must overload the system (muscles) for it to respond by growing in size and strength.
a. Choose one exercise and give two examples of how it can be made more difficult to overload the system.
b. Although light walking is a great place for people to start and can be part of a fitness program, explain why walking doesn't meet the criteria of overload for fit persons.
 
Q4 - Explain the origin of the muscle names below based on how we categorize (classify or name) muscles: pectoralis major, pectoralis minor, biceps femoris.
 
Q5 - One of the greatest obstacles we face in the field is that of the "weakest link". Any action/movement/exercise is limited by the weakest muscle in the entire group. For example, a lateral deltoid raise is limited by the amount of weight that the supraspinatus can lift. When you lean to one side and execute the lateral raise at 30 degrees you take the supraspinatus out of the equation and thus can overload the medial deltoid.

State another example of where action is limited by the weakest link. Explain which muscle is the weakest link and why. Explain how you would develop an exercise program to remedy the issue of the weakest link using the example you stated?
 
Q6 - Explain what a motor unit is made up of.  Describe the role of the synapse, ACH, threshold, and synaptic cleft in the production of movement.

Q7 - Define the two types of motor units and explain how these two different classifications of muscles are utilized differently in endurance activities versus speed and high force activities.

Q8 - A client has come you because (s)he has been diagnosed with chronic low back pain (CLBP). The root source of that CLBP has been determined to be a muscular imbalance. First, define muscular imbalance in one or two statements.
Second, describe the first phase of the training program that you would design for this client. Include in your program a list of primary muscles, both agonists and antagonists that you will be focusing on.
Next, list three to four specific exercises that you would suggest for this client and compare and contrast those exercises based on suitability for the affected muscles.
NOTE: Include the strength training aspect of your program only.


Q9 - For the following popular exercises state the primary joint action. For example, the elbow extends during the concentric phase of a triceps overhead extension. NOTE: you must know how to classify movements into the concentric (power) versus eccentric (preparatory) phase based on muscle action to do this assignment correctly.
a. Shoulder joint. Lateral deltoid raise. Concentric phase.
b. Hip joint. Squat. Eccentric phase.
c. Knee joint. Squat. Concentric phase.
d. Elbow joint. Biceps curl. Eccentric phase.
e. Ankle joint. Gastrocnemius raise. Concentric phase.
