Research round up

Just a few things I've spotted recently that I wanted to highlight but not really to write about in any more detail. Basically coffee might have some good effects and exercise is good for you....

• Coffee Consumption and Coronary Calcification. The Rotterdam Coronary Calcification Study - the study suggests a beneficial effect of coffee drinking against coronary calcification, particularly in women.
• Caffeine Effects on Short-Term Performance during Prolonged Exercise in the Heat. - When combined with water and carbohydrate, caffeine ingestion increases maximal leg force by increasing voluntary activation (i.e., reducing central fatigue).
  
• Exercise and diet enhance fat oxidation and reduce insulin resistance in older obese adults - exercise (and potentaily IF) is good for you - these data show that exercise training improves resting substrate oxidation and creates a metabolic milieu that appears to promote lipid utilization in skeletal muscle, thus facilitating a reversal of insulin resistance. We also demonstrate that leptin sensitivity is improved, but that such a trend may rely on reducing caloric intake in addition to exercise training
• Exercise-induced attenuation of obesity, hyperinsulinemia, and skeletal muscle lipid peroxidation in the OLETF rat - again, exercise is good for you! "even in a genetic animal model of extreme overeating, daily physical activity promotes improved health of skeletal muscle."
