Seven consecutive days of exercise lowers plasma insulin responses to an oral glucose challenge in sedentary elderly.

Objective: To assess the effects of 1 and 7 consecutive days of exercise on glucose and insulin responses to an oral glucose challenge.

Design: Intervention group assessed at baseline and after 1 and 7 days of exercise.

Setting: Academic medical institution.

Effect of exercise training on blood pressure in 70- to 79-yr-old men and women.

Men and women 70-79 yr of age (N = 49) were studied to assess the effect of 6 months of resistance or endurance exercise training on their blood pressure, hemodynamic parameters, and pressor hormone levels. Resistance training consisted of one set of 8-12 repetitions on ten Nautilus machines three times per week. The endurance training group progressed to training at 75-85% VO2max for 35-45 min three times per week for the last 2 months of training.

Cardiovascular responses of 70- to 79-yr-old men and women to exercise training.

This study determined the effects of endurance or resistance exercise training on maximal O2 consumption (VO2max) and the cardiovascular responses to exercise of 70- to 79-yr-old men and women. Healthy untrained subjects were randomly assigned to a control group (n = 12) or to an endurance (n = 16) or resistance training group (n = 19). Training consisted of three sessions per week for 26 wk.
