Naughton Protocol
The Naughton Protocol is a low intensity exercise protocol that has incremental increases in workload. that are more gradual than the Bruce Protocol. Because of these gradual increases, the cardiovascular. Human Exercise – AerobicFitness-GA300 – Labs.

Full Answer

How is the Naughton protocol different from other heart rate tests?

Each testing method has set guidelines for how the test is conducted the best population to receive that particular test. The Naughton protocol is a sub-maximal exercise test designed to keep you in a heart rate zone that is lower than your maximum heart rate. There are several stages, each one slightly more intense than the last.

What is the modified Naughton protocol for cardiorespiratory exercise?

Cardiorespiratory exercise test All subjects performed a symptom-limited treadmill exercise test using the modified Naughton protocol (Supplementary Table 1). The modified Naughton protocol has 2-minute stages and starts at a lower metabolic equivalent of task (MET) workload and increases by 1 MET per stage.[7]

What is the Naughton protocol for ECG?

The Naughton protocol is one of several exercise treadmill clinical testing procedures 1. The purpose of the Naughton protocol is to identify or confirm coronary artery disease in a patient. The ECG sensors record the heart's rhythms and activity as the patient performs the test.

What is the modified Naughton protocol for treadmill testing?

The modified Naughton protocol is recommended for treadmill exercise testing in patients with heart failure.9This protocol is designed to increase the workload by approximately 1 MET (3.5 ml O2/kg/min) for each 2‐minute stage.

What is Naughton protocol used for?

The Naughton treadmill protocol has become a popular treadmill test for use with patients with coronary artery disease (CAD). Frequently, the stages are reduced from 3 to 2 minutes, but there is little information on the prediction of aerobic capacity (AC) based on this abbreviated protocol.

What are the differences between the Naughton and the Bruce protocols?

The only significant difference between the two protocols was the longer exercise duration resulting from the Naughton protocol (17.3 +/- 5.0 vs. 14.8 +/- 2.8 mins, P less than 0.01). The mean maximum heart rates, rate-pressure products and achieved workloads did not differ significantly.

What are the 7 stages of the Bruce protocol?

What is the standard Bruce protocol?

In the standard Bruce protocol, the starting point (ie, stage 1) is 1.7 mph at a 10% grade (5 METs). Stage 2 is 2.5 mph at a 12% grade (7 METs). Stage 3 is 3.4 mph at a 14% grade (9 METs). This protocol includes 3-minute periods to allow achievement of a steady state before workload is increased.

How many Mets are on the Bruce protocol?

Is the Bruce protocol accurate?

The level of significance adopted for all tests was 5%. Results: The ramp protocol showed sensitivity, specificity, and accuracy values of 55.6%, 82.4%, and 76.7%, respectively, whereas the Bruce protocol had results of 77.8%, 64.7%, and 67.4%, respectively.

How long does the Bruce protocol last?

In the most widely used test, called the Bruce protocol, there are seven stages, each one lasting for three minutes. If you get to the last stage, you'll be walking at 5.5 mph up a 20% grade. The goal is to get your heart working up to at least 85% of its maximum capacity.

How do I train for Bruce protocol?

What is the difference between Bruce protocol and modified Bruce protocol?

Conclusions: Modified Bruce protocol has a lighter initial increment, but decreases moderately the capacity of peak exercise due to peripheral fatigue secondary to the first stage of low intensity. Bruce protocol has a higher initial increment but permits to attain higher peak exercise intensities.

What does a Duke treadmill score of 12 mean?

A Duke Treadmill score <–10 indicates high risk for cardiovascular events (predicted 4 year survival was 79%). These patients require further investigation with coronary angiography. A Duke Treadmill score between 4 and –10 indicates intermediate risk.

Is 9 minutes on a treadmill stress test good?

In conclusion, for patients able to manage a 9-minute Bruce protocol, presence/absence of symptoms or electrocardiographic changes is a poor predictor of MPS findings. Irrespective of test findings, however, subsequent cardiac risk is extremely low.
