Scientists wanted to see if measuring muscle activity with sensors on the skin could predict where arm muscles grow after exercise.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Measuring muscle electrical activity with sensors on the skin during bicep exercises doesn’t tell us where the muscle will grow more or less—this finding is from the abstract summary, full study details were not available.
Whether you do preacher curls or inclined curls, your biceps muscles activate in pretty much the same way if you're using a moderate weight and pushing to failure. Basically, the 'effort' your muscles put in is similar for both exercises.
If we use sensors to see which parts of a muscle are working hardest during a workout, those same areas are the ones that will grow the most over time.
