The Claim

In untrained young women, increasing weekly calf training volume from 6 sets to 9 sets does not produce statistically significant additional increases in lateral gastrocnemius, soleus, or total triceps surae muscle thickness compared to 6 or 12 weekly sets, indicating a non-linear dose-response relationship for calf hypertrophy during early-stage resistance training.

Cause and effect

In plain English

For women who are new to weightlifting, doing 9 sets of calf exercises a week doesn't build bigger calves any better than doing 6 or 12 sets. This suggests that when you're just starting out, your calves don't keep growing bigger just because you do more sets.

See the scientific wording

Increasing weekly calf training volume from 6 sets to 9 sets does not yield statistically significant additional gains in lateral gastrocnemius, soleus, or total triceps surae muscle thickness compared to either 6 or 12 weekly sets in untrained young women, suggesting a non-linear dose-response relationship for calf hypertrophy during early-stage resistance training.

  1. Study: Bigger Calves from Doing Higher Resistance Training Volume?

    The study found that doing 9 calf workouts a week didn't build bigger muscles than doing 6 or 12 workouts, showing that muscle growth doesn't always increase steadily with more training.
