The Claim
Changes in antagonist muscle activity during maximal voluntary contraction are not significantly associated with strength gains following 12 weeks of resistance training in healthy young men.
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 healthy young men who train with weights for 12 weeks, the amount of activity in opposing muscles during maximum effort does not reliably predict how much strength they gain.

When you lift weights, your main working muscles get better at firing more strongly and growing bigger, which makes you stronger — but how much the opposing muscles relax or activate during the lift doesn’t affect how much stronger you become.
What the research says
1 studyWhen people lift weights, how much their opposing muscles relax doesn’t predict how much stronger they get — the study found no link between relaxation of those muscles and strength gains after 12 weeks of training.
