,000 experts in nutrition are sharing advances in nutrigenetics and childhood obesity at the 20th International Congress of Nutrition in Granada
Studies show that a moderate level of cardiorespiratory fitness greatly reduces the risk of dying or developing non-communicable chronic diseases whether you are normal weight, overweight or obese
Other studies conclude that over five hours of exercise a week doesn’t have any additional effect on health
The CHANCES project brings together data from 15 cohort studies. The first conclusions will be presented today at the IUNS 20th International Congress of Nutrition
Amongst other things, studies have been carried out on the role of nutrition in osteoporotic fractures and the relationship between levels of 25-hydroxivitamin D and mortality
Obese people who exercise regularly have a lower risk of dying or developing non-communicable diseases over the next ten years than those without weight problems who are not fit, according to the conclusions of a study by prof. Steven Blair, Departments of Exercise Science and Epidemiology & Biostatistics, Arnold School of Public Health, University of South Carolina (USA), presented by the researcher at the round table «Healthy Life Style Promotion», during the IUNS 20th International Congress of Nutrition being held in Granada (Spain).
Blair, an expert on the study of the effects of physical exercise on health, acknowledges that physical activity is one behavior that, along with diet, managing stress, getting adequate sleep and not smoking, may help to bring about a decrease in non-communicable chronic diseases, such as cardiovascular diseases, cancer, diabetes, obesity and respiratory disorders, which are main cause of death in the world.
«We have published dozens of studies in major scientific/medical journals showing that if you have at least a moderate level of cardiorespiratory fitness, your risk of dying or developing non-communicable chronic diseases is greatly reduced, whether you are normal weight, overweight or obese. A good example of how to become moderately fit is walking: three ten-minute walks/day on five days of the week will produce moderate fitness,» comments Professor Blair.
Prof. Steven Blair also commented that more than 300 minutes a week of exercise does not appear to provide substantial additional health benefits. «There is a lot of evidence on the dose response of aerobic training and many health outcomes. Generally the data show a curvilinear association with substantial benefits from moving from very sedentary to moderately active. The curve begins to flatten and show little additional benefits after about 300 minutes of moderate intensity physical activity/week», explained Blair.
