Lately, several research reports have shone an unfavorable spotlight on the impact of prolonged sitting on health and mortality rates.
A new study from the American Cancer Society, The Cooper Institute and the University of Texas suggests that while extended bouts of sitting can lead to health problems, regular exercise may soften the impact.
For those who are suggestible to hypnosis, a short session prior to sleep may improve both the quality and quantity of deep, slow-wave sleep [SWS], according to a study published in the journal Sleep (2014; 37 , 1143-52). Deep sleep is the most restorative sleep, experts say, and as people age, the amount of deep sleep they get diminishes. Researchers in Switzerland are involved in a project to identify psychological and neurophysiological mechanisms underlying the role of sleep for memory and mental health.
Like many athletes, I was recently looking for a leg up on the competition. I was preparing for a fall marathon and already working hard on my running and speed work, but I wondered if by tweaking my diet, I could gain an edge. As a registered dietitian and sports nutrition coach, I was aware of several successful elite athletes who practiced vegetarianism.
Studies have shown that students who are physically active tend to test better academically. Recently, researchers from the University of Madrid tested for possible associations between certain types of physical fitness—motor ability, cardiorespiratory capacity and strength—and scholastic performance.
Are you training for a race or a run or exercising for health benefits? Did you know that recovery from training is actually more important than the training itself, as repair and rebuilding of damaged muscle tissue can occur only during a recovery period.
Charlie Hoolihan, director of personal training for the Pelican Athletic Club in Mandeville, Louisiana, talks below about two crucial steps for recovery:
Let your clients know that their positive outlook on life can contribute to better health for their partners and for themselves. A study published in the Journal of Psychosomatic Research (2014; doi: 10.1016/j.jpsychores.201 4.03.104) found that people with an optimistic spouse had better physical functioning and fewer chronic illnesses than people with a more pessimistic partner—and the relationship between optimism and health did not lessen as more years passed.
It seems that debit card purchases promote the same type of frivolity in children as in adults, but when cards are swiped to pay for school lunches, the impact goes deeper than just free spending. Kids’ food choices also become foolish, according to a study that appeared in the January issue of Obesity (2014; 22 , 24–26).
In another recent study of the effects of exercise on academic performance, researchers looked at how much exercise is required to enhance student attention and reading comprehension. The scientists also wanted to know if results would be different for low and high-income families.
