Study Notes
Exercises and Muscle Contractions
- Isometric exercises involve static contractions of the muscles without joint movement.
Exercises for the Glenohumeral Joint
- Exercises that specifically focus on the muscles working at the glenohumeral joint are called scapular stabilizations.
Muscle Contraction during Isometric Exercises
- During isometric exercises, muscle contraction occurs without a change in muscle length.
Characteristics of Isometric Exercises
- The primary characteristic of isometric exercises is that the muscle contracts, but the joint angle remains the same.
Advantages of Isometric Exercises
- The primary advantage of isometric exercises is that they can help improve strength and muscle endurance without moving the joint.
Muscle Groups Targeted during Isometric Exercises
- The deltoid and rotator cuff muscles are typically targeted during isometric exercises at the glenohumeral joint.
- The pectoralis major muscle is NOT typically targeted during isometric exercises at the glenohumeral joint.
Difficulty of Isometric Exercises
- The difficulty of isometric exercises can be contributed to the intensity of the muscle contraction required.
Distinguishing Isometric Exercises
- Isometric exercises are distinguished from isotonic and isokinetic exercises because they involve a static contraction, whereas isotonic exercises involve a change in muscle length and isokinetic exercises involve a constant speed of movement.
Test your knowledge about isometric exercises, their focus on the muscles working at the glenohumeral joint, and the type of muscle contraction they involve. Explore the static contractions of muscles without joint movement and the primary characteristic of isometric exercises.
