As we grow older we suffer a decline in mental and physical fitness, which can be made worse by conditions like Alzheimer’s disease. A new study, published in the open-access journal Frontiers in Human Neuroscience, shows that older people who routinely partake in physical exercise can reverse the signs of aging in the brain, and dancing has the most profound effect.
É frequentemente repetido, mas é verdade: o exercício mantém você saudável. Ele aumenta o seu sistema imunológico, mantém a mente afiada, ajuda a dormir, mantém o seu tônus muscular e estende a sua vida saudável. Pesquisadores há muito suspeitam que os benefícios do exercício se estendem até o nível celular, mas sabem relativamente pouco sobre quais exercícios ajudam as células a reconstruir organelas-chaves que se deterioram com o envelhecimento. Um estudo publicado em 7 de março em Cell Metabolism descobriu que o exercício – e em particular o treinamento intervalado aeróbico de alta intensidade, como ciclismo e caminhada – impulsiona células a produzirem mais proteínas para suas mitocôndrias (produtoras de energia) e seus ribossomos (produtores de proteínas), efetivamente parando o envelhecimento no nível celular.

Enzymes are most known for their importance in digestion, but they’re actually necessary for all physiological processes.1 Enzymes, which are composed of amino acids, are secreted by your body to catalyze biological functions that otherwise would not occur at physiological temperatures, so they’re absolutely vital for optimal health and life.
TUESDAY, June 18, 2019 (HealthDay News) — High-intensity interval training (HIIT) is an exercise technique done by alternating short bursts of all-out effort in an aerobic activity with periods done at a very slow pace.
THURSDAY, Dec. 20, 2018 (HealthDay News) — Walking and other types of moderate exercise may help turn back the clock for older adults who are losing their mental sharpness, a new clinical trial finds.
The human hippocampus creates new neurons throughout a person’s lifetime—but most scientists thought that this process doesn’t happen as readily to older people past middle age.
Para uma longevidade saudável, buscamos uma baixa frequência de mutações dentro do genoma de nossas células, como mudanças nas sequências do ácido nucleico e mudanças nos cromossomas (DNA). A isto, chamamos de estabilidade genômica ou longevidade. A vitamina Djá mostrou proteger as proteínas e membranas celulares contra o estresse oxidativo, e recentemente um estudo a associou à biologia dos glóbulos brancos – parte do sistema imune do organismo – e à estabilidade genômica.
Monash researchers have unlocked a key process in all human cells that contributes to diseases like cancer and neurodegenerative diseases as well as ageing. The discovery reveals how cells efficiently get rid of cellular junk, which when it accumulates, can trigger death and the health problems associated with getting older.

When it comes to health and disease prevention, your mitochondrial health and function simply cannot be overstated. If your mitochondria are not functioning well, nothing else will either. Optimization of mitochondria is also a central key for life extension. Dr. Lee Know, who is a naturopathic physician, has written a must-read book on this topic called “Mitochondria and the Future of Medicine: The Key to Understanding Disease, Chronic Illness, Aging, and Life Itself.”
