Does Long-Distance Training Saddle Young Cyclists with Fragile Bones?
Young cyclists training to join the Tour de France could be causing irreversible damage to their bones. The combination of cycling extreme distances and restricting caloric intake to reduce weight can decrease bone density to levels that put young athletes at greater risk for serious fractures and, in the long term, developing osteoporosis. It is […]
Exercising first, dieting later protects patients with metabolic syndrome from muscle loss
Younger and older women tend to lose lean muscle mass, along with fat, unless they engage in physical activity before they attempt weight loss, a new study from Israel finds. The results were presented at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago. “To preserve muscle […]
Strict diet suspends development, doubles lifespan of worms
The centuries-long search for the fountain of youth has yielded only a few promising leads, one of which entails an extreme, emaciating diet. A new study of the tiny nematode worm C. elegans begins to explain this marvel of calorie restriction and hints at an easier way to achieve longevity. Researchers at Duke University found […]
High-altitude weight loss may have an evolutionary advantage
Weight loss at high altitudes — something universally experienced by climbers and people who move to higher terrain — may not be a detrimental effect, but rather is likely an evolutionarily-programmed adaptation, according to a new article in BioEssays. Researchers explain that low oxygen causes fat and protein to be broken down, leading to the […]
Saturated fat intake may influence a person’s expression of genetic obesity risk
Limiting saturated fat could help people whose genetic make-up increases their chance of being obese. In a new study, researchers from the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University identified 63 gene variants related to obesity and used them to calculate a genetic risk score for obesity for […]
Marathon runners’ times develop in a U shape
Spanish researchers have demonstrated that the relationship between marathon running times and the age of the athlete is U-shaped. The work shows the unusual fact that it takes an 18-year-old athlete the same amount of time to finish a marathon as a 55- or 60-year-old runner. The 42,195 meters that are nowadays known as the […]
Poor Diet Before Pregnancy Linked with Preterm Birth
University of Adelaide research has for the first time confirmed that women who eat a poor diet before they become pregnant are around 50% more likely to have a preterm birth than those on a healthy diet. Researchers at the University of Adelaide’s Robinson Research Institute investigated the dietary patterns of more than 300 South […]
Mathematics to improve running
How can runners improve their performance, weight and fitness? Amandine Aftalion from the Mathematics Laboratory in Versailles (CNRS/University of Versailles-Saint-Quentin-en-Yvelines) and Frédéric Bonnans from the Center of Applied Mathematics (CNRS/Inria/École polytechnique) have produced a mathematical model to optimize running, which could lead to personal e-coaching customized to each individual’s physiological state. It also confirms a […]
Closing the Gap in Childhood Obesity Forum: A Recap and Call to Action
May 13, 2014, 12:00AM PT in Fitnovatives Blog | A cross-sector cadre of national and regional stakeholders that share the goal of reversing childhood obesity recently converged in New Jersey, the home state of the philanthropic behemoth Robert Wood Johnson Foundation (RWJF). RWJF has invested $ 500 million to reverse childhood obesity […]
From age 30 onwards, inactivity has greatest impact on women’s lifetime heart disease risk
From the age of 30 onwards, physical inactivity exerts a greater impact on a woman’s lifetime risk of developing heart disease than the other well-known risk factors, suggests research published online in the British Journal of Sports Medicine. This includes overweight, the finding show, prompting the researchers to suggest that greater effort needs to be […]
