If we don’t use our muscles, they will wither in atrophy and if we don’t use our brain, our brain will shrink. If the brain is not used, different brain areas will slow down leading to a faster decline in cognitive abilities such as multitasking, learning, memory or movement. A study from Harvard University concluded that lack of brain activity between different areas of the brain means faster aging.
However, what if I told you that is possible to be faster mentally or in better physical shape now than you were 5 or 10 years ago? For the last 10 years, we have being seeing a brilliant phenomena called brain plasticity. Brain plasticity is the brain’s capacity to rewire or regenerate itself, and the key is stimulation. Anytime you stimulate the brain, you are strengthening existing connections and creating new powerful networks. In other words, you are strengthening your brain like a muscle.
According to Dr John Ratey Professor of Psychiatry at Harvard University, exercise is the ultimate way to improve brain plasticity. Nice! But plasticity doesn’t only affect our brains- but affects our muscles as well. Muscle fiber plasticity refers to the capacity of our muscles to change shape, form and structure and there is no age limit, you just need to be consistent with a resistance training program.
