Regular Exercise May Keep Your Body 30 Years ‘Younger’

Regelbunden träning kan hålla din kropp 30 år "yngre". Det finns all anledning att fortsätta träna hela livet. New York Times artikel, från 21/11 2018, bygger på en ny studie där man jämfört olika grupper och kommit till att 70-åringarnas muskler är jämförbara med friska 25-åringars!
"Instead, the muscles of the older exercisers resembled those of the young people, with as many capillaries and enzymes as theirs, and far more than in the muscles of the sedentary elderly. The active elderly group did have lower aerobic capacities than the young people, but their capacities were about 40 percent higher than those of their inactive peers. In fact, when the researchers compared the active older people’s aerobic capacities to those of established data about “normal” capacities at different ages, they calculated that the aged, active group had the cardiovascular health of people 30 years younger than themselves."
