Study Notes

Specific Warm-up

Specific warm-up uses multiple weight sets with increasing intensity.
Specific warm-up repetitions are at a specific % of the RM (repetition maximum).
The specific warm-up uses a 40-60% RM load for 10 repetitions with a 2 minute rest before transitioning to a 60-80% RM load.
The second set of repetitions is 60-80% RM and uses a maximum of five repetitions, with a 2 minute rest.
The final specific warm-up set is 90% RM and uses a maximum of 3 repetitions, with a 5 minute rest.

Strength Testing Guidelines

Strength testing guidelines require an assessment of the experience level of the lifter.
Stronger lifters, such as a lifter who squats 200 kg, may require additional warm-up sets.
The recommended specific warm-up % loads can be modified based on individual lifter experience.
In general, the % loads are decreased for novices and increased for stronger lifters.
It is critical to monitor and address technical errors to ensure proper technique and minimize risk of injury.
During strength testing, lifters should lower and lift the barbell weight in a continuous, fluid motion.
This means no pauses exceeding 3 seconds, and a maximum 5 minute rest between sets.
Minimum weight increments are dictated by equipment availability, exercise requirements, and the specified target error (TE)/coefficient of variation (CV) %.

Strength Testing Challenges

Important questions to consider include whether subjects are prepared for testing and whether testing is truly necessary.
Determine the reason for the test and the intended goal, as this will guide the testing process.

What movements?

Bench press, bench pull, chin ups, lat pulldowns, incline leg press, single leg press, and squats are all examples of exercises that can be performed in strength testing.
Other exercises may also be applicable based on the specific goals and objectives of the testing.

Max Strength Reliability

1 repetition maximum (1RM) tests demonstrate a strong level of reliability.
The intraclass correlation coefficient (ICC) values for squat, bench press, and power clean tests are 0.97, 0.98, and 0.94.
The coefficient of variation (CV%) indicates the variability of measurement, with values of 3.5%, 2.8%, and 4.8% respectively.

Determining Change

Multiple tests in the same conditions are critical for evaluation.
These tests can be performed on the same day for an intra-day reliability assessment or on different days for an inter-day reliability assessment.
The degree of change required to be practically important is determined by the specific testing goals and individual responses.

Test Validity: Military Example

Strength testing can be crucial for evaluating an individual’s ability to perform job-related tasks. Jobs in the military require specific physical capabilities.
Infantry, for example, often have to carry packs exceeding 40 kg, and marching with these loads can exceed 5 km in distance.
Tank crew members frequently load shells weighing approximately 20 kg each.
Clerks often engage in desk operations.
The military’s strength assessment process historically has been biased towards lighter individuals and often lacks comprehensive strength assessments, potentially limiting its effectiveness.
Military testing scales strength standards based on age and sex, which may not be the most appropriate approach.
This method uses the same test for every job, which is not ideal as job demands vary.

Proposed New Military Tests

A new approach for military strength assessment could involve a basic level of testing for all soldiers, recognizing that even clerks may potentially be deployed.
These new tests would assess key physical capacities, including strength, and would not be scaled according to age and sex.
The level of testing would be based on the specific job demands.

What are we Testing?

Maximum dynamic strength is the maximal force that can be generated in a single effort against an external resistance.
This can be assessed using a variety of methods.

Types of Strength Testing

Isokinetic, isometric, and isoinertial tests are all forms of dynamic strength testing.
Isokinetic tests involve constant angular velocity, isometric tests involve a static muscle contraction, and isoinertial tests use a constant gravitational load.

Why Not Isotonic?

Isotonic testing involves muscle tension that changes through the range of motion.
Isoinertial testing is deemed more accurate as the tension remains constant.

Equipment

Force plates and immovable bars are used for isometric testing.
Dynamometers are used for isokinetic testing.
Barbells, dumbbells, and weight plates are used for isoinertial testing.

Isokinetic Dynamometry

Isokinetic dynamometers enable monitoring of peak and average force produced at a constant angular velocity.
This method is popular in clinical settings and is often used in research studies.
It helps to assess muscle asymmetries.
Despite its prevalence, it has been criticized for lacking performance specificity.

Isometric Assessment

Isometric tests assess the maximum force and rate of force development (RFD) through static muscle contractions.
These test subjects produce maximal force using strain gauges, cable tensiometers, force platforms, and load cells.

Isometric Mid-Thigh Pull

The isometric mid-thigh pull (IMTP) is a widely used isometric test to assess lower limb strength.

IMTP Test Norms

IMTP norms provide reference values for comparison.

Other Isometric Tests

Additional isometric tests include hip abduction, hip adduction, shoulder (ASH, IR, ER), back extension, grip strength, groin squeeze, and iso push-ups.

Isoinertial Testing

Isoinertial testing involves a constant load throughout the movement.
Repetition maximum (RM) testing in the isoinertial domain is commonly used for large muscle mass movements.
This method requires the ability to manage maximal loads.
