What is the exercise method for older people to activate their muscles than young people?

BySteve Shupe

Although it is a well-known fact that exercise has a positive effect on people's health and life, it is a fact that exercise affects cells, how unknown is the relationship between exercise and people's age There are also many parts. So, in the USMayo ClinicResearchers investigated what kind of exercise will affect the muscles of young people and the elderly.

The Best Exercise for Aging Muscles - The New York Times

The subjects were 72 males and females, "healthy, sedentary life living" divided into three groups, 30 years old, under 30 years old, and over 64 years old, subjects had blood glucose levels, muscle After measuring the state of the gene activity in mitochondria, etc., we performed specific exercise therapy randomly assigned. This "randomly assigned exercise therapy" means that a group performs intense weight training several times a week, another group alternately repeats high load and low load using an aero bicycleInterval trainingThree times a week, and the third group performs moderate aerobics and light lifting two to three times a week. The fourth group did not exercise at all for comparison.

We measured blood glucose levels again after 12 weeks, and all the people who exercised experienced improvement of health condition, and blood sugar level was getting better as well. At this time, naturally, the group who did heavy weight training experienced muscle weight increase / strengthening, and the group who performed the interval training had the most durability up. What is interesting is that the influence of interval training differs depending on the elderly and young people. Examination of the muscle cells of young subjects who performed interval training showed that 274 genes were active, which was "170" of the group who exercised moderate exercise, "74" of the group who performed intense weight training It was also a big figure. On the other hand, when examining the muscle cells of the elderly group, genes of "19" in the group with moderate exercise and "33" in the group with intensive weight training were active, compared with interval training "400" genes were active in the group that did. The influence of interval training was more strongly seen in elderly people than young people.

It is believed that when the gene is activated by exercise, the ability of mitochondria in muscle cells to generate energy is affected. The group who conducted the interval training in this experiment repeatedly took a vigorous pedaling for 4 minutes and then took a 3 minute break and then repeatedly piercing again but the older bicycle ride gives health As I told the influence, such exercise has had a big influence on the muscle.

Dr. Sreekumaran Nair of the Mayo Clinic says "If the health of the cells in the muscles is impaired by age, it will be repaired by exercise, especially if it is intense exercise," the older the older, Because there are exercises to activate the muscles more than young people, "I am not" too late "to gain the benefit of exercise."
