Survival of the Fittest—Promoting Fitness Throughout the Life Span

Personal Activity Intelligence and Mortality in Patients with Cardiovascular Disease: The HUNT Study

“…17,27,28 Indeed, higher levels of CRF have been associated with improved cardiovascular risk profile and lower mortality risks in healthy individuals and those with CVD. [29][30][31][32][33][34] The PAI metric takes into account intensity and time spent performing PA and explains why the PAI metric is a good predictor of mortality risk.…”

Combined Effect of Sauna Bathing and Cardiorespiratory Fitness on the Risk of Sudden Cardiac Deaths in Caucasian Men: A Long-term Prospective Cohort Study

“…Increasing levels of PA and exercise training, particularly aerobic activity generally confers good CRF, 37 which has consistently shown to be strongly protective of vascular and non-vascular disease as well as mortality via physiological and metabolic processes. 38 However, the level of CRF is not solely determined by physical exercise or PA, but a combination of PA, genetics, and other lifestyle factors.…”

Is There an “Asymptote of Gain” Beyond Which Further Increases in Cardiorespiratory Fitness Convey No Additional Benefits on Mortality and Atrial Fibrillation?

“…Most pregnant women suffer from nausea and vomiting with a high frequency and often change their eating habits in their gravid state in accordance with food aversions, which are typically tied to strong odors, including coffee, spicy foods, and high protein meals that include meats and fish. 3 Thus, we maintain our assertion of the critical importance of the combination of her gravid state and nutritional challenges of those times as likely operational in producing clinical manifestations of hypothyroidism. To the Editor: The debate exists on whether the dose-response relationship between physical activity (PA) and mortality benefits is, in fact, a curvilinear, U-shaped, or J-shaped curve.…”

“…To the Editor: The debate exists on whether the dose-response relationship between physical activity (PA) and mortality benefits is, in fact, a curvilinear, U-shaped, or J-shaped curve. 1,2 Cardiorespiratory fitness (fitness), highly reflective of habitual PA, is a strong protector against various adverse health outcomes including cardiovascular disease (CVD) 3,4 and is also associated with lower health care costs. 5 It has been suggested that high levels of fitness may be at least as important as lower body mass index in the prevention of CVD.…”
