The Claim
Low-frequency resistance training in rats is associated with no change in serum creatine kinase activity or serum lactate concentrations, indicating that this training protocol does not induce systemic muscle damage or metabolic stress.
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 rats do resistance exercises less often, their blood doesn't show signs of muscle damage or stress—so this kind of workout seems gentle on their bodies.
See the scientific wording
Low-frequency resistance training in rats is associated with no change in serum creatine kinase activity or serum lactate concentrations, suggesting this protocol does not induce systemic muscle damage or metabolic stress.
When muscles are pulled gently but repeatedly during light resistance exercises, the physical stretch activates signals inside muscle cells that tell them to build more protein and grow bigger. This happens without breaking muscle fibers or using up energy in a way that releases stress chemicals into the blood.
What the research says
1 studyWhen rats did light resistance workouts just twice a week, their blood didn't show any signs of muscle damage or stress—even though their muscles got bigger. This means the workout was gentle but still effective.
