Children who skip meals more likely to have excess body fat, increased cardiometabolic risk

Children who skip main meals are more likely to have excess body fat and an increased cardiometabolic risk already at the age of 6 to 8 years, according to a Finnish study. A higher consumption of sugary drinks, red meat and low-fat margarine and a lower consumption of vegetable oil are also related to a higher cardiometabolic risk.

Dr. Shirin Towfigh reveals possible symptoms that may help identify sports hernias

When playing sports that involve rapid bursts, twists, and movements, a variety of groin injuries, including hernias, can occur. No matter how strong or flexible someone is, their lower abdominal wall can still weaken because of constant or particularly straining rapid movement.

Preventive effect of tamoxifen drug for breast cancer remains virtually constant for 20 years

The preventive effect of breast cancer drug 'tamoxifen' remains virtually constant for at least 20 years - with rates reduced by around 30 per cent - new analysis published in The Lancet Oncology reveals.

Researchers develop new how-to exercise program to help MS people stay more physically active

Fatigue and pain, along with other symptoms, prevent many people with multiple sclerosis (MS) from exercising. But a new how-to guide for a home-based exercise program, tested by researchers at Case Western Reserve University's nursing school and the Lerner Research Institute at the Cleveland Clinic, offers a way for people with MS to stay more physically active.

Study: Long-term endurance training alters epigenetic pattern in the human skeletal muscle

A new study from Karolinska Institutet in Sweden shows that long-term endurance training in a stable way alters the epigenetic pattern in the human skeletal muscle. The research team behind the study, which is being published in the journal Epigenetics, also found strong links between these altered epigenetic patterns and the activity in genes controlling improved metabolism and inflammation.

Vitamin C may reduce exercise-induced bronchoconstriction and respiratory symptoms

Physical activity increases oxidative stress, and therefore, as an antioxidant vitamin C might have particularly evident effects on people who are participating in vigorous exercise. In several studies, vitamin C administration attenuated the increases in oxidative stress markers caused by exercise. Furthermore, vitamin C is involved in the metabolism of histamine, prostaglandins, and cysteinyl leukotrienes, all of which appear to be mediators in the pathogenesis of exercise-induced bronchoconstriction.

Weight-loss surgery may reduce lower urinary tract symptoms

Metabolic syndrome is linked with an increased frequency and severity of lower urinary tract symptoms, but weight loss surgery may lessen these symptoms. The findings, which come from two studies published in BJU International, indicate that urinary problems may be added to the list of issues that can improve with efforts that address altered metabolism.

Study reveals how elite Kenyan athletes succeed in long-distance races

The Journal of Applied Physiology has published an article by Jordan Santos-Concejero of the Faculty of Physical Activity and Sport Sciences of the University of the Basque Country, and entitled `Maintained cerebral oxygenation during maximal self-paced exercise in elite Kenyan runners'. This is a pioneering study in the world of the physiology of exercise, given that it describes for the first time that elite Kenyan athletes have greater brain oxygenation during periods of maximum physical effort, and which contributes to their success in long-distance races.
