Aerobic exercise training-induced reductions in abdominal fat and glucose-stimulated insulin responses in middle-aged and older men

Article Abstract:

A study to test the effect of aerobic exercise training on glucose-stimulated insulin responses in those who are middle-aged and older has been carried out over 9 months using moderate-intensity aerobic exercise training in 17 men. It was found that the decrease in glucose-stimulated insulin secretion with aerobic exercise training is mediated, at least in part, by reductions in abdominal fat. Regular physical exercise may prevent or ameliorate conditions associated with hyperinsulinemia.

Insulin action after resistive training in insulin resistant older men and women

Article Abstract:

This article examines the effects of a six-month resistive training protocol on insulin action in a sample of insulin-resistant subjects over the age of sixty-five. Findings indicate that physical training results in improved insulin action and increased muscular strength among older insulin-resistant adults.

A comparison of longitudinal changes in aerobic fitness in older endurance athletes and sedentary men

Article Abstract:

It has been found that the longitudinal decline in maximal aerobic capacity (VO(sub.2.max)) in older male endurance athletes is very dependent on continued magnitude of the training stimulus. The majority of the athletes lowered training levels over time, bringing longitudinal reduction in VO(sub.2.max) 2-3 times the size of those predicted by cross-sectional analyses or those seen longitudinally in sedentary peers. A cohort study with mean follow-up of 8.7 years was carried out in 42 healthy, middle-aged and older endurance athletes and 47 healthy, sedentary men.
