How do you calculate VO2max from Bruce protocol?

Results

1. VO2max (ml/kg/min) = 14.76 – (1.379 × T) + (0.451 × T²) – (0.012 × T³)
2. Women: VO2max (ml/kg/min) = 2.94 x T + 3.74.
3. Young Women: VO2max (ml/kg/min) = 4.38 × T – 3.9.
4. Men: VO2max (ml/kg/min) = 2.94 x T + 7.65.
5. Young Men: VO2max (ml/kg/min) = 3.62 x T + 3.91.

How accurate is the Bruce treadmill test?

Data gathered from each protocol demonstrated that the usage of the ramped Bruce protocol achieved more consistent results in comparison across all BMI groups in achieving 80%–85% of their age-predicted maximum heart rate.

How long is the Bruce protocol?

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.

What is considered a high VO2 max?

Most female athletes have a score between 60-85 ml and male athletes between 70-85. Some athletes even record a score greater than 90. The highest Vo2 Max scores come from male cross-country skiers, they record values up to 96 ml/kg/min. Female XC skiers record scores in the region 72-80 96 ml/kg/min.

How long does the Bruce protocol last?

What is the Bruce protocol for a stress test?

The Bruce protocol is a standard test in cardiology and is comprised of multiple exercise stages of three minutes each. At each stage, the gradient and speed of the treadmill are elevated to increase work output, called METS. Stage 1 of the Bruce protocol is performed at 1.7 miles per hour and a 10% gradient.

What is the standard Bruce Protocol?

The Bruce protocol is a standard test in cardiology and is comprised of multiple exercise stages of three minutes each. At each stage, the gradient and speed of the treadmill are elevated to increase work output, called METS.

What is Bruce Protocol Stage 3?

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. The modified Bruce protocol has 2 warmup stages, each lasting 3 minutes. The first is at 1.7 mph and a 0% grade, and the second is at 1.7 mph and a 5% grade.

What is modified Bruce Treadmill protocol?

The modified Bruce protocol is an alteration in the protocol so that the treadmill is initially horizontal rather than uphill, with the first few intervals increasing the treadmill slope only. The test can detect evidence of angina pectoris ( chest pain and discomfort), a previous heart attack,…
