Document Summary
Changes in (a-v) o2 differences with acute exercise. 5 is going out there is 75% extraction, but on whole body, there is only 25: a cardiac patient with blockages in coronary arteries they have limited ability to increase coronary blood flow and they are already extracting a lot lectureee. Sbp: increases ~ 8-12 mmhg per met: met 3. 5 ml/kg/min resting metabolism. If jumps too much, then considered an exaggerated bp response: normal resting bp and then shooting up, criteria of stopping if it goes 250 mmhg. Dbp: increase or decrease or no change: signficance: dbp if it increases it is directly related to myocardial ischemia. Three bouts of aerobic exercise: 1 bout at 30%, 2 bout- 65, 3rd bout- 100% One day, they did it on arms and other on leg. Exaggerated bp responses as high as 480/360 mmhg: for a short period of time can go up to this during weight training.
