The Claim
In heavy resistance-trained male youth rugby league players, transitioning from a maximal strength training mesocycle (70–100% 1RM) to a higher-volume hypertrophy training mesocycle (35–70% 1RM) is associated with greater increases in delayed onset muscle soreness (DOMS) by 41.6 ± 22.7% and a modest increase in creatine kinase (CK) levels by 26.7 ± 47.8%, indicating greater acute muscle damage following higher training volume.
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.
When young male rugby players switch from heavy lifting to doing more reps with lighter weights, they feel more muscle soreness and show signs of more muscle damage in blood tests.

What the research says
1 studyThe study found that when young rugby players switched from heavy lifting to higher-rep workouts, their muscles were more sore and showed more signs of damage, just like the claim says.
