Effects of weight loss vs aerobic exercise training on risk factors for coronary disease in healthy, obese, middle-aged and older men: a randomized controlled trial
Article Abstract:
Weight loss may be the most effective way for middle-aged and older overweight men to reduce their risk factors for coronary artery disease. Researchers randomized 170 healthy, middle-aged or elderly overweight men to a reducing diet, aerobic exercise or no intervention (the control group). Forty-four men completed the 9-month diet, 49 completed the 9-month exercise program and 18 men made up the control group. At the end of the study, 45% of the men in the diet group had lost more than 10% of their body weight. Diet significantly reduced their glucose and insulin levels as well as their total cholesterol, LDL cholesterol and blood pressure compared to the control group. The men in the exercise group experienced reductions in their total and LDL cholesterol compared to the control group, but not to the same extent as those in the diet group.

Left ventricular diastolic filling performance in older male athletes
Article Abstract:
The filling of the left ventricle of the heart after contraction is impaired by aging and this appears to be true even in older male athletes. This process, called diastolic filling, has an early component and a late component. Researchers measured maximal oxygen consumption and heart function determined by echocardiography in 17 young sedentary men, 23 older sedentary men and 16 older athletes. The athletes had the highest oxygen consumption rates, but their early diastolic filling rates were lower than those of the young sedentary men and similar to those of the older sedentary men. However, their late diastolic filling compensated for this loss, a condition also seen in the older sedentary men. This indicates that the decline in early diastolic filling is a consequence of aging, not prolonged inactivity.

Repetitive bilateral arm training and motor cortex activation in chronic stroke
Article Abstract:
Specific rehabilitation therapy improves upper extremity function in chronic stroke survivors. A specific rehabilitation therapy that improves arm function is associated with reorganization of cortical networks, in patients with chronic motor impairment following stroke.
