Turn back your aging clock with high-intensity workouts

Recent research finds exercise program can stimulate mitochondria, the energy producing proteins.

CPHHS Assistant Professor Matt Robinson was recently involved in a study to determine which type of exercise is most effective for removing damaged proteins from the body and regenerating new ones.

“One of the theories of aging is that the muscle proteins accumulate damage, in the same way that rust accumulates on cars,” Matt says. “Those damaged proteins need to be replaced, so we need to remove them and make new ones. Exercise is a really good way to do that. We compared three different exercise programs to see how they change proteins and which specific types of proteins are affected.”

Matt and his colleagues at the Mayo Clinic recruited participants in two different age groups – 18-30 years of age and 65-80 years of age. The groups participated in three types of exercise – HIIT, resistance weight-training and a combination of lower-intensity cardio and resistance training.

The study found that HIIT has the greatest impact on proteins within the mitochondria, which were among thousands of muscle proteins that were examined. In particular, they found large increases in the cellular machinery, the ribosomes, that make new proteins and increases in the rate at which new proteins were being made.

The times don't add up. 10 min warm-up, four 7 min HIIT cycles and a 5 min cool down doesn't add up to 40 mins. Its 43 mins.
