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.
Structural mechanics or mechanics of structures is the computation of deformations, deflections, and internal forces or stresses (stress equivalents) within structures, either for design or for performance evaluation of existing structures. It is one subset of structural analysis. Structural mechanics analysis needs input data such as structural loads, the structure's geometric representation and support conditions, and the materials' properties. Output quantities may include support reactions, stresses and displacements.
Aerobic exercise (also known as endurance activities, cardio or cardio-respiratory exercise) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. "Aerobic" is defined as "relating to, involving, or requiring oxygen", and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. Aerobic exercise is performed by repeating sequences of light-to-moderate intensity activities for extended periods of time.
Le calcul des structures et la modélisation concernent deux domaines distincts : d'une part les applications spécifiques au patrimoine architectural, mobilier et naturel et d'autre part les applications industrielles. Le calcul des structures et leur modélisation est utilisé dans les domaines : de la conservation et mise en valeur du patrimoine architectural, mobilier et naturel, dans le cadre de missions d’assistance à la maître d’œuvre ou au maître d’ouvrage permettant d’arrêter un programme de travaux, d’applications industrielles.
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.
