The Claim
In highly trained individuals, six weeks of either low-velocity-loss or high-velocity-loss resistance training produces no significant changes in leg press power, squat jump height, or whole-body lean mass as measured by DEXA.
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.
After six weeks of resistance training, highly trained people do not show measurable improvements or declines in leg press power, squat jump height, or lean body mass, regardless of whether the training allowed low or high levels of velocity loss.
See the scientific wording
In highly trained individuals, neither low- nor high-velocity-loss resistance training protocols produce significant changes in leg press power, squat jump height, or whole-body lean mass measured by DEXA after six weeks of training.
In highly trained people, muscles are already adapted to generate maximum force, so training until fatigue doesn't recruit more muscle fibers or trigger more growth than training with less fatigue. The body reaches a point where further fatigue doesn't increase muscle activation or protein building, so power and muscle mass stay the same regardless of how hard the training is pushed.
What the research says
1 studyFor experienced lifters, whether they stop their sets early or push until they slow down a lot, it doesn’t make them jump higher, get more powerful, or gain more total muscle mass after six weeks. Both ways of training worked the same.
