The magic key to reversing aging is exercise. That is the claim of high-intensity interval (HIIT) exercise experts.
In a 12-week test conducted by Mayo Clinic 72 sedentary adults in two age groups, 18 to 30, and 65 to 80, were divided into three groups: High-intensity interval cycling, weights for strength training, and a combined cycling and strength-training program.
At the end of the testing all participants had improved aerobic capacity and gained more lean muscle, but the muscles in the HIIT group experienced a higher ability to take in oxygen and produce energy. The muscles of the younger group improved by 49% and the older participants by 69%.
The muscle cells also showed an improved ability to build proteins needed to create muscle cells, meaning the loss of muscle mass which occurs with aging can be lessened with exercise.
