Effect of different training frequencies on maximal strength performance and muscle hypertrophy in trained individuals—a within-subject design

Randomized Controlled Trial

Human

2022

This study had the same people do different workout schedules and compared results within each person, which cuts out personal differences and makes the results more accurate—exactly what the claim says within-subject designs do.

When you compare both training styles on the same person (one leg vs. the other), you get clearer results than comparing different people, because everyone’s body responds differently.

By training both legs of the same person—one with short breaks, one with long breaks—the study made sure differences weren’t due to people being naturally different, making the results more reliable.
