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.
