You’ve heard it before, and you’ll hear it again: Physical exercise is very important in combatting aging, both the physical aging of your body, as well as the mental aging of your mind.
In this post, we draw together links to four articles on a recent new study about the way that exercise combats physical aging, together with a link to the study abstract. The study was carried out at the Mayo clinic in Rochester, MN, and demonstrated that exercise — particularly high-intensity interval training (HIT) — has profound effects at the cellular level. It may even reverse some of the aging effects in muscle cells, as well as possibly other cells in the body.
The Mayo researchers utilized 36 men and 36 women, broken into two age groups: 18-30 years old and 65-80 years old. Each age group was split into three exercise groups: HIT biking together with treadmill walking, weight training, and mixed biking and weight training. Each group worked out 5 days a week for 12 weeks. Muscle change assessments were based on biopsies taken from the volunteers’ thigh muscles, compared with biopsies taken from a sedentary control group.
All of the exercise groups showed muscle improvement, particularly increases in muscle cell mitochondrial capacity, which is the energy source for all cells. Strikingly, the younger HIT group showed a 49% increase, while the older HIT group showed a dazzling 69% increase. The study also showed that exercise leads to improvement in protein-building ribosomes.
