Ben Johnson Squat 1rm?

Utilizing repetition tests with sub-max weight and weighing the results against a 1RM, competition or training max, is an unwise and inaccurate measure of fiber type dominance/composition.

The training program that one has been on can easily sway the results one way or the other.

Simple training adjustments may increase the oxidation potential of type IIa and IIb/x fiber.

For this reason, with all due respect to those who place value on the significance of any RM weighed against a 1RM, this vehicle of indication is science fiction.

Short of muscle biopsy, the most accurate measure of white fiber dominance, or not, is to assess activities that are a direct reflection of the capacity of white fiber; i.e. short sprints, jumps, and throws

Using 1RMs and reps with heavy weights is doomed from the start in this regard as the last direction you should look in, with respect to identifying to what extent a subject is gifted with explosive potential, is slow activities.

Take a look at the attached chart:

Any way you slice it, the closer the athlete is to scoring 100 on the test the more white fiber they have.

Are the 3 jumps double leg like a frog jump?

Also in these tests how do you rank someone that has scores better in one part of the test compared to another?

Last one (sorry to be a pest!!!) Do you use these test in your program? I’ve seen it in track but not in football…

Thanks
