How does load percentage relate to force output?

In a linear F-V model, force output scales proportionally with load percentage. At 80% 1RM, relative force is approximately 80% of maximum isometric force.

Why estimate force rather than just using weight?

Weight and force are different. At high velocities, force output exceeds bar load due to acceleration. During eccentric phases, force can exceed 1RM significantly.

Is this calculator useful for prescribing training?

Yes. Combining force estimates with velocity data enables more precise training load prescription than using % 1RM alone, particularly for power-focused athletes.
