It is unknown whether lifestyle, including mental stimulation, and appropriate training interventions, may directly improve spatial navigation performance and its underlying neural substrates. Here we report that healthy younger and older men performing a cognitively demanding spatial navigation task every other day over 4 months display navigation-related gains in performance and stable hippocampal volumes that were maintained 4 months after termination of training. In contrast, control groups displayed volume decrements consistent with longitudinal estimates of age-related decline. Hippocampal barrier density, as indicated by mean diffusivity estimated from diffusion tensor imaging, showed a quadratic shape of increased density after training followed..."

Better a sprint than a marathon: Brief intense exercise better than endurance training for preventing cardiovascular disease

Better a sprint than a marathon: Brief intense exercise better than endurance training for preventing cardiovascular disease: "Exercise is important for preventing cardiovascular disease, especially in children and adolescents, but is all exercise equally beneficial? New research reveals that high intensity exercise is more beneficial than traditional endurance training."
