 Just over a handful studies we could bring together from the last week and some of them are more for the geeks than for general personal training clients but intriguing nonetheless. Highlights:
Eating more fruit and vegetables linked to less stress, study finds Eating a diet rich in fruit and vegetables is associated with less stress, according to new research. The findings revealed people who ate at least 470 grams of fruit and vegetables daily had 10 per cent lower stress levels than those who consumed less than 230 grams.

Researchers found that activity-specific physiological adaptations in the muscles and increased signaling and neurogenesis in the hippocampus underlie these improvements. Findings also suggested that benefits can potentially be optimized by tailoring exercise time and intensity.

Source: University of Pittsburgh Different physical activity 'cocktails' have similar health benefits A new study describes multiple ways to achieve the same health benefits from exercise -- as long as your exercise 'cocktail' includes plenty of light physical activity. Source: Columbia University Irving Medical Center Stair climbing offers significant cardiovascular and muscular benefits for heart patients A team of researchers who studied heart patients found that stair-climbing routines, whether vigorous or moderate, provide significant cardiovascular and muscular benefits.
