Study Notes
Isometric Muscle Contractions
- Isometric muscle contractions produce tension without joint movement.
- Isometric exercises are used when motion is restricted or not possible.
- Isometrics help to:
- Decrease muscle atrophy
- Facilitate muscle contraction
- Decrease pain
- Improve circulation
Isometric Exercise Guidelines
- The "Rule of 10" is commonly followed:
- Gradually increase force for 2 seconds
- Maintain force for 6 seconds
- Decrease force for 2 seconds
Exercise Progressions
- Progress from slow to fast exercises
- Progress from simple to complex exercises
- Progress from stable to unstable exercises
- Progress from low force to higher force exercises
Isometric Training
- Start with submaximal contractions and progress to maximal contractions
- Perform exercises at multiple angles
- Increase intensity by:
- Increasing repetitions
- Increasing effort
- Increasing the length of hold
