The Claim
Five weeks of either low-load blood flow restriction or high-load resistance training did not improve finger endurance, as measured by intermittent isometric contractions at 57% of maximal voluntary contraction, in advanced climbers.
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 advanced climbers, two types of strength training—low-load training with restricted blood flow and high-load training—did not lead to better finger endurance after five weeks of training, when tested using a specific grip endurance task.
See the scientific wording
Finger endurance, measured by intermittent isometric contractions at 57% of MVC, did not improve after five weeks of either low-load blood flow restriction or high-load resistance training in advanced climbers, indicating that these protocols do not enhance muscular endurance under this specific test condition.
When you train your fingers with heavy weights or light weights with your arm squeezed tight, your finger muscles get bigger and stronger, but they don't get better at handling repeated squeezing without getting tired. This is because the training makes the muscles stronger by adding more muscle fibers, but it doesn't improve how well the muscles use oxygen or clear out waste products during long, repeated efforts.
What the research says
1 studyEven after five weeks of training fingers with either light weights with tight bands or heavy weights, climbers didn’t get better at holding onto holds repeatedly with short breaks. So, these types of training don’t help with this kind of endurance.
