Variations in exercise systolic blood pressure in physically active middle-aged men with normal and elevated blood pressure.

abstract：:Little if any research has examined the variability in time to exhaustion (TTE) during submaximal treadmill running. This study investigated the test-retest reliability of submaximal treadmill TTE as a measure of endurance capacity. 16 endurance-trained males (n=14) and females (n=2) completed a run to exhaustion at 7...
