The Claim
Twelve weeks of complex training combining resistance and plyometric exercises twice weekly results in significantly greater improvements in countermovement jump height (19.4%) and reactive strength index (7.2%) compared to traditional resistance training in male collegiate dancers with no prior strength training experience.
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 male collegiate dancers with no prior strength training experience, twelve weeks of combined resistance and plyometric exercises performed twice weekly leads to larger increases in jump height and reactive strength compared to traditional resistance training alone.
See the scientific wording
Twelve weeks of complex training, combining resistance and plyometric exercises twice weekly, leads to significantly greater improvements in countermovement jump height (19.4%) and reactive strength index (7.2%) compared to traditional resistance training in male collegiate dancers with no prior strength training experience, suggesting enhanced lower-limb explosive power.
A heavy lift temporarily makes muscles more responsive, so when a person immediately jumps, their muscles produce more force faster by using stored energy in tendons and firing more muscle fibers at once.
What the research says
1 studyStudy: Effects of 12 weeks of complex training on lower limbs strength and power in collegiate dancers
Dancers who did a mix of lifting weights and jumping exercises got much better at jumping high and bouncing back quickly than dancers who only lifted weights — exactly what the claim says.
