The Claim
Sixty days of bed rest causes faster electrically evoked twitch contraction and relaxation kinetics in the knee extensors and plantar flexors, indicating a shift toward faster muscle contractile properties independent of fiber type changes.
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.
Sixty days of bed rest results in faster muscle contraction and relaxation in the quadriceps and calf muscles, reflecting a change in muscle contractile speed that is not due to changes in muscle fiber type.
See the scientific wording
Sixty days of bed rest leads to faster electrically evoked twitch contraction and relaxation kinetics in knee extensors and plantar flexors, indicating a shift toward faster muscle contractile properties independent of fiber type changes.
When muscles are not used for a long time, the pump that pulls calcium back into the storage compartment inside muscle cells works faster. This causes the muscle to relax more quickly after contracting, making the whole twitch response faster without changing the type of muscle fibers.
What the research says
1 studyAfter lying in bed for 60 days, leg muscles responded faster to electrical pulses, meaning they contracted and relaxed more quickly — even though the muscle fibers didn’t change type. This was proven by the study’s direct measurements.
