How high-intensity interval training keeps you young

It’s off-repeated but true: exercise keeps you healthy.

It boots your immune system, keeps the mind sharp, helps you sleep, maintains your muscle tone, and extends your healthy lifespan.

Researchers have long suspected that the benefits of exercise extend down to the cellular level, but know relatively little about which exercises help cells rebuild key organelles that deteriorate with aging.

A study published in Cell Metabolism found that exercise -and in particular high-intensity interval training in aerobic exercises such as biking and walking- caused cells to make more proteins for their energy-producing mitochondria and their protein-building ribosomes, effectively stopping aging at the cellular level.

Increasing muscle strength can improve brain function

Increased muscle strength leads to improved brain function in adults with Mild Cognitive Impairment (MCI), new results from a study led by the University of Sydney has revealed.

With 135 million people forecast to suffer from dementia in 2050, the study’s findings—published in the Journal of American Geriatrics today—have implications for the type and intensity of exercise that is recommended for our growing ageing population.

Mild Cognitive Impairment defines people who have noticeably reduced cognitive abilities such as reduced memory but are still able to live independently, and is a precursor to Alzheimer’s disease.
