More Muscle, More Muscles Capillaries? | Study

Описание: It is evident that we will ALL lose muscles when we get older, unfortunately. Even though that sarcopenia is an inevitable fact, we can still start working out today to keep on moving when we get older, instead of being an old grunt. I mean what can you lose other than having a great feeling and a pump comes along the way.

Methods: Forty-six healthy older (70 ± 4 y) men participated in a trial during which basal muscle protein synthesis rates were assessed using stable isotope tracer methodology. Blood and muscle biopsy samples were collected to assess post-absorptive muscle protein synthesis rates over a 3-hour period. Immunohistochemistry was performed to determine various indices of muscle fiber capillarization, size, type distribution, and myonuclear content/domain size. Dual energy x-ray absorptiometry scans were performed to determine whole-body and appendicular lean tissue mass.

The present study provides further evidence that muscle fiber capillarization may be a critical factor in the regulation of skeletal muscle maintenance in healthy older men.

You can deter having loss of muscle mass by working out and investing in more capillaries.
