The Claim

Even though the muscles grew bigger, the body didn’t make more muscle or connective tissue proteins at a faster rate — meaning the growth happened without the usual increase in protein building.

Source: Low-load blood flow-restricted resistance exercise produce fiber type-independent hypertrophy and improves muscle functional capacity in older individuals.

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 plain English

Even though the muscles grew bigger, the body didn’t make more muscle or connective tissue proteins at a faster rate — meaning the growth happened without the usual increase in protein building.

See the scientific wording

Six weeks of low-load blood flow-restricted resistance exercise does not increase myofibrillar or connective tissue protein synthesis rates in healthy older adults aged 56–75, despite causing muscle hypertrophy.

What the research says

1 study

  1. Study: Low-load blood flow-restricted resistance exercise produce fiber type-independent hypertrophy and improves muscle functional capacity in older individuals.

    Even though the older adults’ muscles got bigger after six weeks of light exercise with blood flow restriction, their bodies didn’t make more of the main muscle or connective tissue proteins — which is surprising but true according to the study.
