The Claim
In advanced male judo athletes, 6 weeks of supplemental resistance training at either 30% or 80% of 1RM, performed with or without reaching muscular failure, does not significantly improve explosive power generation capacity as measured by theoretical maximum power (Pmax), rate of force development (RFDmax), or force-velocity relationship parameters, indicating that increases in muscle size and isometric strength do not lead to enhanced dynamic power output in already highly trained individuals.
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.
Even if elite male judo athletes lift weights for 6 weeks, it doesn’t seem to make them more explosive — getting stronger or bigger muscles doesn’t necessarily help them punch or throw faster.
See the scientific wording
In advanced male judo athletes undergoing 6 weeks of supplemental resistance training, there is no significant improvement in explosive power generation capacity, as measured by theoretical maximum power (Pmax), rate of force development (RFDmax), or force-velocity relationship parameters, regardless of training load (30% or 80% 1RM) or whether repetitions are performed to failure, suggesting that gains in muscle size and isometric strength do not translate into enhanced dynamic power output in already highly trained individuals.
In elite judo athletes who are already very strong and trained, making muscles bigger or stronger through weight training doesn’t make them punch or throw faster because their nerves can’t signal the muscles to contract any quicker than they already do — even when training hard or to failure, their bodies don’t improve how fast they can produce force, as shown in 10.1371/journal.pone.0307841.
What the research says
1 studyEven when elite judo athletes did weight training to get stronger or bigger muscles, their ability to generate fast, explosive power didn’t improve. So, just getting stronger doesn’t always mean you’ll throw or punch faster.
