The Claim

In resistance-trained individuals, performing calf raises with initial partial range of motion (from maximal dorsiflexion to neutral) for 8 weeks results in a slightly greater increase in medial gastrocnemius muscle thickness (mean increase: 9.5%) compared to full-range repetitions followed by past-failure partials (mean increase: 6.7%), though the difference of 0.40 mm is uncertain and not statistically conclusive.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

If you're someone who lifts weights and you do calf raises using only part of the motion for 8 weeks, your calf muscles might grow a little more than if you do full-range reps plus extra partials at the end—but the difference is so small that we can't be sure it's real.

  1. Study: Resistance Training Beyond Momentary Failure: The Effects of Past‐Failure Partials Versus Initial Partials on Calf Muscle Hypertrophy Among a Resistance‐Trained Cohort

    This study found that doing calf raises only partway up at the start might make your calf muscles grow a tiny bit more than doing full movements and then pushing past failure, but the difference is so small that we can't be totally sure it's real.
