Study Notes
Isokinetic Tests
- Isokinetic tests of strength utilize a slower velocity setting compared to isokinetic tests of power.
Tests of Muscular Power
- The countermovement vertical jump and standing long jump are recognized as tests of muscular power.
- 1-RM bench press and YMCA bench press do not qualify as tests of muscular power.
Biceps Curl Mechanics
- During a biceps curl with constant resistance, tension produced by the biceps brachii varies throughout the range of motion.
1-RM Testing Steps
- Start with a warm-up set of 5-10 reps at 40-60% of the estimated 1-RM.
- Follow with a second warm-up set of 3-5 reps at 60-80%, then rest briefly.
- Attempt the 1-RM after 3-5 minutes of rest, increasing weight conservatively until failure to find the maximum weight lifted.
Vertical Jump Testing Procedure
- Begin by adjusting the Vertec to a known height and record the client's standing reach height.
- Instruct the client to perform a countermovement jump, aiming for maximum height.
- Record the height of the highest vane reached over three trials and subtract the reach height to calculate the vertical jump score.
Muscle Balance Ratio
- The muscle balance ratio for agonist and antagonist groups (e.g., elbow flexors vs. extensors) is not universally 1:1.
YMCA Bench Press Test
- This test evaluates auxotonic muscular endurance.
Senior Fitness Tests
- The arm curl and 30-second chair stand exercises are used in the Senior Fitness Tests to assess functional muscular fitness in older adults aged 60-94.
Muscular Power and Aging
- Muscular power tends to decline at a faster rate with age compared to muscular strength or endurance.
1-RM Testing and Age Groups
- 1-RM testing is not contraindicated for children under 12 and older adults above 60 years.
