Flashcard 1

•

Front: What is Muscular Analysis?

•

Back: Muscular Analysis is the process of understanding how muscles work together during movement. It is essential for creating effective exercise programs1.... This analysis includes understanding that muscles are usually grouped by their concentric function and that muscles work in paired opposition to an antagonistic group3.

Flashcard 2

•

Front: What is an example of how muscles work in paired opposition?

•

Back: Elbow flexors work together as an agonist group, while the triceps brachii and anconeus (elbow extensors) work in opposition as an antagonist group3. In this case, the elbow extensors cooperate by lengthening to allow the flexors to perform their task3.

Flashcard 3

•

Front: Why is the upper extremity often considered one of the body's weakest areas?

•

Back: The upper extremity often lacks sufficient strength and endurance1. Specific conditioning exercises and activities should be intelligently selected to improve strength and endurance, which is essential for improved appearance, posture, and more efficient skill performance1.

Flashcard 4

•

Front: Why is a balanced approach to exercise important?

•

Back: Typical weight room exercises often concentrate only on the anterior shoulder, which can lead to strong and tight anterior muscles with weak and flexible posterior muscles if a balanced approach is not taken2.

Flashcard 5

•

Front: Why are muscular strength, endurance, and flexibility important?

•

Back: Muscular strength, endurance, and flexibility are crucial for skillful physical performance, appearance, posture, and body maintenance5. Medical and allied health professionals emphasize the development of muscle groups through resistance training and circuit training activities5. Overall muscular development is needed for athletes and non-athletes5.

•

Front: What is the importance of Mechanical Kinesiology?

•

Back: Mechanical kinesiology is emphasized in physical education and athletic skill development6. However, mechanical principles are not valuable to performers without adequate strength and endurance of the muscular system6.

Flashcard 7

•

Front: What are the key elements to consider when analyzing an activity?

•

Back: When analyzing an activity, it's important to:

◦

Determine which muscles are performing the movement4.

◦

Know what type of contraction is occurring4.

◦

Know what kinds of exercises are appropriate for developing the muscles4.

Flashcard 8

•

Front: What is the Kinetic Chain Concept?

•

Back: The Kinetic Chain Concept describes how extremities consist of bony segments linked by a series of joints. Any single link in an extremity may be moved individually without affecting other links if the chain is open, however, if the chain is closed or attached, movement of one link will lead to movement of other links7.
