Exercise Physiology

Terms in this set (12)

To measure total body energy production during exercise one can
use VO2 and the thermal equivalent measured during exercise
Total body heat production during exercise is
the difference between the exercise total body energy production and the exercise work accomplished
Ornish's research demonstrated that exercise
low fat & cholesterol diet, and stress reduction can reverse CAD
Blair's work demonstrated that exercise
can lower mortality risk even in those with elevated risk factors
ECG ST segment depression indicates
a sign of cardiac ischemia
The obese adolescent weight loss study that Dr. Marks was a co-author on demonstrated that
the diet, behavior modification, and exercise program had the greatest improved shift in health risk frequency
To call a graded exercise test a stress test you must
at least monitor ECG and measure blood pressure during exercise
A clinical sign is
what you can detect on an assessment--e.g. ECG
Jane has CAD and had the following stress test results (her age predicted max HR is 170 b/min):
Stage, HR, SBP/DBP, ECG, Symptoms/signs:

Rest, 60, 110/55, Normal, None
1, 100, 125/60, Normal, none
2, 110, 130/60, Normal, none
3, 130, 140/65, Normal, none
4, 150, 145/60, 1 mm ST Dep. +1, Chest discomfort
5, 165, 150/55, 4 mm ST Dep. +3, Chest pain Test Stopped

What would you use for her max HR in calculating her heart rate reserve?
150 (When Jane started to experience chest discomfort)
A CAD patient has just showed up for his stress test and lets you know that his chest pain has become worse (i.e. it's unstable). The stress test is
delayed until chest pain is stabilized. An absolute contraindication for testing
An example of a symptom is
patient tells you he/she has chest pain
The sensitivity of a diagnostic test for a given health problem is
what percentage of the individuals with the health problem are detected
