The Claim
After eight weeks of resistance training at the 70% thigh site, muscle thickness increases by a mean of 0.09 cm, regardless of the load applied or the use of blood flow restriction.
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 resistance training, the thickness of muscle at the 70% thigh site increases by an average of 0.09 centimeters, whether the training uses heavy or light weights and whether or not blood flow is restricted.
See the scientific wording
Muscle thickness increases at the 70% thigh site after eight weeks of resistance training regardless of load or blood flow restriction, with a mean change of 0.09 cm, suggesting that even very low-load training can stimulate some hypertrophy.
When muscles are worked even with light weights until they are very tired, the stretching and pulling of muscle fibers sends signals that turn on a system inside muscle cells that builds new muscle proteins, making the fibers thicker over time.

1 studyStudy: Blood flow restriction does not augment low force contractions taken to or near task failure
Even with very light weights, people’s thighs got slightly thicker after eight weeks of training — proving that you don’t need heavy weights to see some muscle growth.
