Answer:
DO NOT cross your legs or ankles when you are sitting, standing, or lying down. DO NOT bend too far forward from your waist or pull your leg up past your waist. This bending is called hip flexion. Avoid hip flexion greater than 90 degrees at a right angle.
Explanation:
The available options are:
a) Push-up plus off a wall → shoulder IR/ER → seated DB press
b) Shoulder IR/ER → push-up plus → seated DB press
c) Shoulder IR/ER → seated DB press → push-up plus
d) High-rep bench press → shoulder IR/ER → abdominal crunch
Answer:
A. Push-up plus off a wall -> shoulder IR/ER -> seated DB press
Explanation:
A push-up plus off a wall is an example of a closed chain exercise as the arm is fixated to a stationary surface.
It also make your shoulder blades to move freely, making serratus anterior stronger, a vital muscle that keeps scapula stable and helps it rotate upward. This in turn reduces shoulder impingement when push-ups plus off a wall is done.
Shoulder IR/ER also helps to correct the imbalance in the rotator muscles of the shoulder.
Also, seated DB press strengthens all muscles of the shoulder in a functional way.
Answer:
True
Explanation:
<u>Rotational and linear motions are analogous to each other.</u>
<u>The inertia of a body in a linear motion is its mass.</u> This can be seen from Newton's second law of thermodynamics:
F = ma
The larger the value of the force, the larger the inertia is (m) and the slower it accelerates.
<u>The inertia of a body in a rotational body is it moment of inertia (I).</u> Both I and m are same but I depends on both the shape and mass of the rotating body.
For example, The inertia of a solid disk with mass M and radius R is:
Hence, the statement is true.
