Evaluating Strength Flashcards
What do fast glycolytic muscle fibres lead to compared to other muscle fibres
A greater and faster rate of contraction
Describe the motor units associated with fast glycolytic muscle fibres
Large, up to 700, larger neurones than other fibres which lead to faster impulses. These motor units have the highest explosiveness and highest maximal strength
What is a muscle cross section
A muscle cross section is the amount and size of muscle fibres
The larger the cross section of muscle the….
Greater the strength + force of contraction
Name 3 factors effecting cross section of a muscle
Age, gender and training
What are the two tests for strength endurance
- Abdominal curl test
2. Press up test
Describe the abdominal curl test
Performing sit ups in time with a bleep. The test is progressive and the performer continues until failure. The test is based on the time lasted (amount of beeps)
Describe the press up test
The performer completes as many repetitions as possible (hands shoulder width apart) mentaning good form. The score is based on repetitions completed
Describe the 1RM test
The performer selects an exercise to test the strength of a specific muscle. The score is based on the weight lifted
Describe the grip strength dynamometer
The performer takes 3 turns with each hand + records the best score shown on the dial. It should be dialled back to zero after each attempt
What are the 2 tests for maximum strength
- 1RM test
2. Grip strength dynamometer
What is the test for explosive/elastic strength
- Vertical jump test
Describe the explosive/elastic test
Performer marks their standing reaching height on a wall. Then jumps as high as possible vertically and marks their height. The score is based on the difference between the marks
Name 3 evaluative points for strength tests
- Equipment availability and costs
- If specific muscle groups can be isolated or not
- Is their a clear procedure and reliable results
