Study Notes
Muscle Contraction and Endurance
- Maximal force in a single contraction at a specified velocity is termed muscular power.
- The ability of a muscle group to exert submaximal force over extended time is known as muscular endurance.
- When there is no joint movement during a contraction, it is referred to as an isometric contraction.
Grip and Core Endurance Tests
- For a grip endurance test with a dynamometer, the handle should be squeezed for 1 minute.
- The V-sit test assesses the isometric endurance of trunk flexors.
- The side bridge test evaluates the isometric endurance of lateral flexors.
Free Weights and Strength Testing
- Disadvantage of testing dynamic muscle strength with free weights includes needing greater spotting for safety; however, free weights do not have smaller accurate weight increments.
- Tips for spotting include using a power rack for overhead exercises and maintaining a stable base, while being weaker or shorter than the client is not permissible.
Strength Assessment Recommendations
- The American College of Sports Medicine endorses the bench press for upper body and the leg press for lower body strength assessments.
- During 1-RM testing, recommended weight increases are 5-10% for upper body and 10-20% for lower body exercises.
- For upper body endurance, the ACSM suggests using the push-up test.
Core Stability and Balance
- The Sahrmann Core Stability Test requires movements while maintaining lumbopelvic stability in a neutral position.
- Strength differences between the right and left body sides should not exceed 15%.
- The Senior Fitness Test for older adults includes the biceps curl for upper body strength and the 30-second chair stand for lower body strength.
1-RM Testing in Children
- For 1-RM testing in children, guidelines recommend performing 6 reps with a light load and 3 with a heavier load prior to testing, stressing the importance of safety in strength assessments.
