What is submaximal exercise testing definition?
Submaximal exercise testing is the testing option for those individuals that do not wish to undergo VO2max testing, or, for whom VO2max testing is inappropriate. Gas analysis is performed utilizing the HPL's ParvoMedics metabolic analyzer while the participant exercises at less-than-maximum efforts.
Why do we use submaximal tests to estimate VO2max?
Background: Aerobic capacity (VO2max) is a strong predictor of health and fitness and is considered a key physiological measure in the healthy adult population. Submaximal step tests provide a safe, simple and ecologically valid means of assessing VO2max in both the general population and a rehabilitation setting.

What does submaximal physical activity mean?
Submaximal graded exercise is any physical activity whose intensity increases at regular intervals up to but never exceeding 85 percent of your maximum heart rate, according to the American Council on Exercise.
What is the difference between submaximal exercise and maximal exercise?
In a maximal exercise test RPE and RER will steadily increase until the end of the test (Figure 2A), where as in a submaximal endurance exercise test these parameters will plateau (Figure 2B). Although not required, it can be beneficial to perform a pulmonary function test before performing an exercise test.
What is the most accurate submaximal exercise test?
The most accurate way to assess aerobic capacity is the direct measurement of maximal oxygen uptake (VO2max) during a graded exercise test (GXT); however, the direct measurement of VO2max is often limited to laboratory, clinical, and research settings.
What is submaximal heart rate?
Submaximal Heart Rate: Heart rate throughout various intensities between resting and maximal heart rate. Moderate submaximal intensity ranges from 50-75% of maximum heart rate, whereas vigorous submaximal intensity ranges from 75-99% of maximum heart rate.
What can submaximal cycle ergometer testing predict?
The YMCA Sub-Maximal Cycle Ergometer Test is a submaximal cycle ergometer aerobic fitness test. Based on the participant'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 is a single exercise test?
According to ACE, a single exercise testing session can provide an accurate indication of your current aerobic fitness level, and can be a useful tool for tracking your fitness improvements across a consistent workout program. Regular exercise can decrease your heart-rate response to a given exercise intensity.
What is the best method of exercise testing?
Preferred methods of exercise testing use the stationary bike and the treadmill. Many exercise test styles have been designed for each apparatus, with minor differences. During a typical graded fitness test, your weight, height, blood pressure and heart rate are recorded, and your maximum heart rate is calculated.
What is a YMCA cycle test?
The YMCA Cycle Test is a multi-s tage sub-maximal test that can also help you estimate your aerobic fitness, however it is more applicable for cyclists who are already familiar with the equipment. This test should be administered by an exercise specialist as it requires specific procedures and equipment, including a cycle ergometer and a blood pressure cuff.

The Rockport Walk Test is a sub-maximal exercise test that can be done on a treadmill or on a track. It is used for people who are generally less fit and cannot run for very long, if at all. Walk as fast as you can for one mile, but at a pace that you can sustain for the entire distance.
What is a submaximal fitness test?
During a sub-maximal aerobic fitness test, heart rate or distance covered is used to estimate VO2 max. Unlike direct VO2 max measurement, during a sub-maximal test the heart rate should not rise above a pre-determined maximum -- usually 85 percent of the estimated maximal heart rate based on age. While sub-maximal graded exercise tests are usually done in a laboratory or gym setting under professional supervision, several sub-maximal field tests can be done on your own with a timer and/or a heart rate monitor.
Is VO2 max a good indicator of fitness?
Considerations. VO2 max is a good indicator of fitness level, but it changes over time with changes in the frequency or intensity of aerobic exercise. For this reason, experts recommend periodic VO2 max measurement or estimation for individuals who want to track aerobic capacity.
What are submaximal tests?
There are numerous submaximal tests from which to choose. These tests have been developed to meet the needs of people with various functional limitations and disabilities and the needs of older adults. In our opinion, however, inappropriate selection may lead to either understressing or overstressing the individual. Such understressing or overstressing of the person, in our view, can lead to invalid conclusions because of ceiling or floor effects, and the testing may be hazardous. The goal of testing should be to produce a sufficient level of exercise stress without physiologic or biomechanical strain. Factors that we believe should be considered in selecting the appropriate test include the person's primary and secondary pathologies and how these pathologies physically affect the person's daily life. Other factors include cognitive status, age, weight, nutritional status, mobility, use of walking aids or orthotic or prosthetic devices, independence, work situation, home situation, and the person's needs and wants. People who may be medically unstable and at risk for an arrest may need to be tested in the presence of a cardiologist or pulmonary specialist or by a physical therapist in a specialized setting where emergency services are on hand. The population for which a given test was developed, the degree of validity and reliability of measure-ments obtained with each test, and test sensitivity also should be considered ( Appendix ). Reports in the literature on the common submaximal tests described in this article vary with respect to the adequacy of establishing validity, reliability, and sensitivity; thus, test interpretation may be limited. These limitations should be considered in the selection of each test. Physical therapists should determine what information will be added by performing an exercise test and how that information will alter clinical decision making.
What is submaximal exercise testing?
Compared with maximal exercise testing, submaximal exercise testing appears to have greater applicability to physical therapists in their role as clinical exercise specialists. This review contrasts maximal and submaximal exercise testing. Two major categories of submaximal tests (ie, predictive and performance tests) and their relative merits are described. Predictive tests are submaximal tests that are used to predict maximal aerobic capacity. Performance tests involve measuring the responses to standardized physical activities that are typically encountered in everyday life. To maximize the validity and reliability of data obtained from submaximal tests, physical therapists are cautioned to apply the tests selectively based on their indications; to adhere to methods, including the requisite number of practice sessions; and to use measurements such as heart rate, blood pressure, exertion, and pain to evaluate test performance and to safely monitor patients.
What is CAFT test?
The Canadian Aerobic Fitness Test (CAFT), formerly known as the Canadian Home Fitness Test, is unique in that it was designed to promote fitness testing at home. The CAFT was developed on a sample of 1,544 individuals (699 men and 845 women) aged 15 to 69 years. 44 The CAFT is a measure of fitness and is based on the duration of the step test and a 10-second recovery of HR ( Tabs. 3 and 4 ). Norms for the recovery HR in men and women have been reported, 44 and a “Physical Fitness Evaluation Chart” for various age groups is available ( Tab. 5 ). In addition, Jette et al 45 developed a regression equation for the CAFT to predict V̇ o2 max. A sample of 59 individuals, aged 15 to 74 years, completed the CAFT and then underwent a progressive treadmill test to evaluate V̇ o2 max.
What is maximal exercise?
Maximal exercise testing has a role in the assessment of maximal aerobic capacity or functional work capacity. Because people are frequently limited by cardiopulmo-nary, musculoskeletal, and neuromuscular impairments and complaints such as exertion, dyspnea, fatigue, weakness, and pain during their activities of daily living, maximal testing is often contraindicated or of limited value. In people without cardiopulmonary or musculo-skeletal impairments, the reserve capacity of the cardiopulmonary and musculoskeletal systems is thought to be barely tapped during daily activities. 22 In people with pathology, this reserve can be greatly reduced, and a greater than usual proportion of a person's maximal capacity may be needed to perform routine activities. 23
Why is it important to monitor the individual during the pacing test?
We believe, therefore, that it is essential to monitor the individual during the test to ensure that she or he is responding appropriately. Familiarizing the individual with the pacing required for the test may require some time.
What is the importance of exercise testing?
The space for testing must be sufficient to minimize injury should the patient fall or have an arrest. All physical therapists should have current certification in cardiopulmonary resuscitation. Emergency procedures and basic equipment need to be in place to ensure that the individual has immediate care until paramedical or medical assistance arrives. There are other critical needs for exercise testing. Basic emergency supplies, including a sugar source for people with diabetes, should be on hand. A portable oxygen source and suction device should be accessible. People who are stable and who have a history of angina should have their antianginal medication, and the physical therapist should have access to this medication. Monitoring equipment should be maintained and regularly calibrated.
What is the correlation between 20 MST and V o2 max?
Paliczka et al 61 confirmed the validity of measurements obtained with the 20-MST by demonstrating a high correlation between 20-MST and V̇ o2 max ( r =.93) , as well as with a 10-km race time ( r =−.93). The test has been further validated on active women. 62 The 20-MST was reported to yield valid and sufficiently sensitive measurements such that the intensity of exercise could be modified for children with asthma. 63
