The upper limit of cardiorespiratory fitness associated with longevity: an update

Résumé

In 2013, mortality reductions with improving cardiorespiratory fitness (CRF) have been suggested to persist until 13 METs. More recently, accumulating evidence from large-scale studies suggests that mortality from all causes decreases with increasing CRF levels, apparently without upper limit of CRF. However, when baseline CRF is assessed in later life, upper limits of CRF decrease depending on the individual fitness level at baseline and the volume and intensity of physical activity performed during follow up. Consequently, both a CRF level as high as possible during early adulthood, achieved by appropriate exercise interventions, and a small CRF decline during later life, by continuation of regular physical activity, will help to optimize longevity.

Condition physique
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest along with a formal recovery plan. Before the Industrial Revolution, fitness was defined as the capacity to carry out the day's activities without undue fatigue or lethargy.
Fitness
thumb|Démonstration d'exercices de fitness. Le fitness (abréviation de l'expression anglaise physical fitness, « forme physique »), aussi appelé la gymnastique de forme ou l'entraînement physique, désigne un ensemble d'activités physiques permettant au pratiquant d'améliorer sa condition physique et son hygiène de vie, dans un souci de bien-être. Le fitness trouve ses origines dans l'aérobic (gymnastique modelant le corps par des mouvements effectués en musique), qui lui-même naît de la danse jazz.
Neurobiological effects of physical exercise
The neurobiological effects of physical exercise are numerous and involve a wide range of interrelated effects on brain structure, brain function, and cognition. A large body of research in humans has demonstrated that consistent aerobic exercise (e.g., 30 minutes every day) induces persistent improvements in certain cognitive functions, healthy alterations in gene expression in the brain, and beneficial forms of neuroplasticity and behavioral plasticity; some of these long-term effects include: increased neuron growth, increased neurological activity (e.
