However beneath the hood, the mechanisms of muscular hypertrophy are extra complicated. There are three main elements regarding your exercises that have an effect on how a lot muscle you construct: (2)
- Metabolic Stress
- Mechanical Rigidity
- Muscle Injury
It’s not totally understood precisely how these elements work together. The type of coaching you do to get a great pump going, although, will primarily affect hypertrophy due to the metabolic stress it creates.
Nevertheless, it’s value noting that in recent times, up to date analysis has leaned additional into the deserves of mechanical rigidity particularly, deriding the concept that all three elements are of equal significance.

- Nevertheless, findings are combined. One other paper famous “important correlations” between BFR and energy improvement, however no robust correlation for muscle progress. (5)
- One 2013 research made an especially compelling remark. The authors state that “BFR can stimulate muscle hypertrophy to the identical diploma as high-intensity coaching…” (6)
BFR definitely has some compelling proof behind it. However specialists like Greg Nuckols advise warning with regard to creating BFR pump coaching the whole lot of your exercise routine. “In my expertise, BFR works greatest when added in for just a few weeks at a time,” Nuckols says.
