Cardiovascular responses to exercise in middle-aged men after 10 days of bedrest.
The cardiorespiratory response to 10 days of continuous recumbency was assessed in 12 healthy men, age 50 +/- 4 years, who underwent supine and upright graded maximal exercise testing before and after bedrest. The decrease in peak oxygen uptake after bedrest was greater during upright exercise (15.1%, p less than 0.05) than during supine exercise (6.1%, NS): from 25.8 +/- 5.2 to 21.9 +/- 4.5 ml...
متن کاملExercise conditioning in middle-aged men after 10 days of bed rest.
Of 12 healthy men with a mean age 50 +/- 4 years who had been at bed rest for 10 days, six were randomly assigned to perform individually prescribed physical exercise daily for 60 days after bed rest (exercise group) and six simply resumed their customary activities (control group). Exercise group subjects were significantly more active than control subjects during this interval (p less than .0...
متن کاملCardiovascular adaptations to 10 days of cycle exercise.
We hypothesized that 10 days of training would enhance cardiac output (CO) and stroke volume (SV) during peak exercise and increase the inotropic response to beta-adrenergic stimulation. Ten subjects [age 26 +/- 2 (SE) yr] trained on a cycle ergometer for 10 days. At peak exercise, training increased O2 uptake, CO, and SV (P < 0.001). Left ventricular (LV) size and function at rest were assesse...
متن کاملHemodynamic Responses to Exercise in Clinically Normal Middle-aged Men and in Those with Angina Pectoris.
The effects of aging on the hemodynamic responses to exercise in men are at present poorly understood. Although a number of studies investigating these responses in young people have been reported, relatively few have been carried out in subjects older than 35 years. Granath, Jonsson, and Strandell (2) have described the results of exercise upon cardiac output and vascular pressures in a group ...
متن کاملFactors related to ST-segment depression after exercise in middle-aged Chinese men.
Ninety-four or 7% of 1,346 healthy middle-aged Chinese men who underwent a graded treadmill test of maximal exercise showed post-exercise ST-segment depression. Stepwise linear discriminant function analysis showed that the major factors associated with this response were systolic blood pressures at maximal exercise, age, and certain resting ECG abnormalities, and to a lesser extent, systolic a...
