LESSON 09 - HUMAN MOVEMENT QUIZ Flashcards
Static balance exercises often involve _______________.
The Correct Answer is:
Narrowing the base of support
Why?
To work on static balance with a client or class participant, the fitness professional can make the individual’s base of support narrower to stimulate adaptation to the imposed demand. Widening the base of support lessens the balance challenge.

When comparing the medial epicondyle of the humerus to the lateral epicondyle of the humerus, which of the following statements is correct?
Choose One
The medial epicondyle is more toward the back of the body than the lateral epicondyle
The medial epicondyle is more away from the midline of the body than the lateral epicondyle
The medial epicondyle is more toward the front of the body than the lateral epicondyle
The medial epicondyle is more toward the midline of the body than the lateral epicondyle
The Correct Answer is:
Latin: humerus, umerus meaning upper arm, shoulder,
The medial epicondyle is more toward the midline of the body than the lateral epicondyle
Why?
The term “medial” means “toward the midline of the body,” while the term “lateral” means “away from the midline of the body.”

Which of the following is NOT one of four types of tissue found in the human body?
Choose One
Nervous
Vascular
Muscular
Epithelial
The Correct Answer is:
Vascular
Why?
The four primary types of tissue are muscular, nervous, connective, and epithelial.

Performing a cartwheel requires static balance.
The Correct Answer is:
FALSE
Why?
Dynamic balance is the ability to reestablish a new base of support following linear or rotary motion of the whole body (like doing a cartwheel) when the line of gravity is shifted beyond the base of support. Static balance, by contrast, is the ability to maintain balance while standing still.

Joint mobility must never be attained by compromising joint stability.
The Correct Answer is:
TRUE
Why?
Joint mobility is the range of uninhibited movement around a joint or body segment. Joint stability is the ability to maintain or control joint movement or position. Both joint mobility and stability are attained by the interaction of all components surrounding the joints and the neuromuscular system. Joint mobility must never be attained by compromising joint stability.
ACE Essentials of Exercise Science, p. 114
When looking to improve joint stability, open-chain exercises should be performed.
The Correct Answer is:
FALSE
Why?
In an open-chain exercise, the end of the chain farthest from the body is free, such as in a seated leg extension. Open-chain exercises tend to involve more shearing forces at the joints, while closed-chain exercises tend to emphasize compression of joints, which helps stabilize the joints. Additionally, closed-chain exercises involve more muscles and joints than open-chain exercise, which leads to better neuromuscular coordination and overall stability at the joints.
ACE Essentials of Exercise Science, p. 114
Developing strength and endurance in stabilizer muscles is not important unless you are a highly skilled athlete.
The Correct Answer is:
FALSE
Why?
Optimal movement performance requires that the body’s muscles work together to produce force while simultaneously stabilizing the joints. People who have weak stabilizer muscles often exhibit problems with performing proper, efficient movement, which may lead to pain and/or injury. Therefore, functional training that focuses on the body’s stabilizing musculature is often incorporated into rehabilitation and/or post-rehabilitation programs.
Performing an isometric squat requires static balance and stabilization.
The Correct Answer is:
TRUE
Why?
In an isometric action, no visible movement occurs and the resistance matches the muscular tension. Isometric muscle action, such as an isometric squat, can be used in balance and stabilization training.
