At all ages, women had a lower exercise capacity than men. 9 minutes 15 seconds = 9.25 minutes). Age differences in mean maximal and submaximal heart rates were small. The Bruce protocol was used to carry out the exercise tests. If you get to the last stage, you'll be walking at 5.5 mph up a 20% grade. The site is secure. Sevil M, Rashid M, Hajizadeh I, Park M, Quinn L, Cinar A. IEEE Trans Biomed Eng. How many minutes is good on a stress test? While other factors like an individuals age are somewhat considered (for example, there is a different equation for young men and men), the Bruce Treadmill Test is primarily determined by the length of time that an athlete can successfully run on a treadmill set to specific running speeds and difficulties of inclines. A nomogram to select the optimal treadmill ramp protocol in subjects with high exercise capacity: validation and comparison with the Bruce protocol. Let's assume you are female and 30 years old. More specifically, the speed for each stage of the Bruce Treadmill Test is as follows: 1.7, 2.5, 3.4, 4.2, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5 (all speeds are in mph). The first is at 1.7 mph and a 0% grade, and the second is at 1.7 mph and a 5% grade. Is one of the predicted maximum heart rate is 220 40 = 180 will live years! The person assisting you with your test will increase the speed and angle of the incline every 3 minutes until you reach your target heart rate.

Lets pretend youre 30 years old and a woman. [citation needed], The test score is the time taken on the test, in minutes. Two were age and gender. The median exercise time for men aged 76 to 80 years was 7:22 (minutes:seconds) and for women was 6:00 and significantly decreased in both genders as age increased (p <0.001). When the athlete can no longer continue, stop the test and enter the number of minutes he/she was able to run. A multiple regression equation including age, gender, physical activity habits, and body weight resulted in a slightly improved prediction (R2 = 0.88; standard error of estimates = 3.1 mL kg min-1). Results of VO2 max are expressed as mL/kg/min. A stress test is a way of measuring how well your heart works under greater demands namely, exercise. This protocol includes 3-minute periods to allow achievement of a steady state before workload is increased.

A 5-year survival rate of 97% is indicated by a low risk score (score less than 5). The Bruce protocol is used commonly and is well described in many studies involving exercise testing. The speed must also be increased for each stage, and this increase in speed is set according to the standards of the Bruce Treadmill Test. A stress test involves walking on a treadmill until your heart rate reaches an established rate based on your age. The only true way to know if youre concerned about heart blockages is to undergo a coronary arteriogram.
