Typically during a Bruce Protocol, heart rate and rating of perceived exertion are taken every minute and blood pressure is taken at the end of each stage (every three minutes). There are Bruce protocol tables available for maximal (competitive athletes) and sub-maximal (non-athletic people) efforts.
A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate. [1]
With a maximal stress test the level of exercise is increased until the person's heart rate will not increase any higher, despite increased exercise. A fairly accurate estimate of the target heart rate, based on extensive clinical research, can be estimated by the formula 220 beats per minute minus patient's age.
An elite athlete's heart recorded during a maximum effort workout maintaining over 180 bpm for 10 minutes. The maximum heart rate (HR max) is the age-related highest number of beats per minute of the heart when reaching a point of exhaustion [28] [29] without severe problems through exercise stress. [30]
The Harvard step test, in scientific literature sometimes referred to as the Brouha Test, is a type of cardiac stress test for detecting and diagnosing cardiovascular disease. It is also a good measurement of fitness and a person's ability to recover after a strenuous exercise by checking the recovery rate.
Moderate intensity exercise is defined as exercise that increases heart rate to 55-74% of maximum heart rate. [42] High intensity exercise increasing the heart rate to 70-100% of maximum heart rate for shorter intervals is at least as effective, and this type of exercise may increase oxygen uptake by the heart compared to moderate intensity ...
The stress test can result in three outcomes: Pass, Partly Pass and Fail, based on the comparison of the quantified risks to acceptable risk exposure levels and a penalty system. Phase 3: Decision, during which the results of the stress test are analyzed according to the goal and objectives defined in Phase 1. Critical events (events that most ...
The scale was constructed to roughly correlate to 10% of heart rate in a healthy 20-year-old. [8] This explains why the rating starts at 6, which would roughly correspond to a resting heart rate at about 60 per minute. In older individuals, the correlation becomes higher than 10% at the high-end of the scale, as maximum heart rate declines with ...
