Cross-Validation of the YMCA Submaximal Cycle Ergometer Test to Predict VO2max. Maximal oxygen uptake (VO2max) is an important indicator of health-risk status, specifically for coronary heart disease (Blair et al., 1989).
How accurate is the YMCA cycle ergometer test?
The YMCA submaximal cycle ergometer test: under-predicted participants 1 and 2’s VO2 max, over-predicted participant 3’s VO2 max, and was 100% accurate in estimating subject 4’s VO2 max.
What is the purpose of the cycle ergometer test?
The purpose of a cycle ergometer is chiefly to measure cardiac performance—specifically, maximum heart rate and oxygen uptake.
What does the YMCA cycle ergometer test measure?
The YMCA Sub-Maximal Cycle Ergometer Test is a submaximal cycle ergometer aerobic fitness test. Based on the subject’s heart rate response to several submaximal workloads, we can predict what workload, and therefore VO2max, they would have reached if they had continued until their maximum heart rate.
What are the advantages of using a submaximal cycle ergometer test?
advantages: simple test to administer, reasonably accurate and appropriate for ECG monitoring during exercise.
How do you calculate workload on a cycle ergometer?
Power (P) is defined as the amount of work per time unit. Work on a Monark ergometer is calculated as; W = Braking load x Distance Where one revolution on the crank equals six meters in distance and the breaking load is in kiloponds or Newtons.
How do you predict VO2 max?
Calculating VO2 Max
- VO2 max = maximum milliliters of oxygen consumed in 1 minute / body weight in kilograms.
- VO2 = (milliliters of air inhaled per minute)(percentage of oxygen in the air inhaled) / (milliliters of air exhaled per minute)(percentage of oxygen in the air exhaled)
- VO2 max = 15.3 x (MHR/RHR)
Are submaximal tests accurate?
Submaximal tests are less accurate, but are safer and faster than a maximal test. Submaximal tests use heart rate response to submaximal power output to estimate VO2max ; thus, any factor that alters heart rate response reduces the accuracy of the test.
Are submaximal tests reliable?
Conclusion: Moderate evidence was found for reliability, validity and acceptability of submaximal exercise tests in patients with chronic pain, fibromyalgia or chronic fatigue. There is no evidence about maximal exercise tests in patients with chronic pain, fibromyalgia and chronic fatigue.
What does an ergometer measure?
Exercise physiology Ergometry (from Greek ergos=work and metry=to measure) is the measurement and quantification of human physical performance. Traditionally, ergometric measurements evaluate the endurance capabilities of a person, although strength capabilities can also be quantified using appropriate tests.
