The Claim
Eight weeks of resistance training with very low-load (15% 1RM), with or without blood flow restriction, results in a mean increase of 7.9 repetitions in muscular endurance, independent of training load or blood flow restriction use.
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 eight weeks of low-intensity resistance training, whether or not blood flow restriction is used, people can perform an average of 7.9 more repetitions in endurance tests.
See the scientific wording
Eight weeks of resistance training with very low-load (15% 1RM) with or without blood flow restriction leads to a modest increase in muscular endurance, with a mean improvement of 7.9 repetitions, regardless of training load or BFR use.
Doing many reps with light weights builds up waste products in the muscle, which signals the muscle to adapt by improving its ability to handle fatigue, so it can keep working longer before getting tired.
What the research says
1 studyStudy: Blood flow restriction does not augment low force contractions taken to or near task failure
People who lifted very light weights for eight weeks got better at doing more reps before getting tired—no matter if they used a special band to restrict blood flow or not. Everyone improved by about the same amount.
