Submaximal tests are used because
maximal tests can be dangerous
in individuals who are not considered normal healthy subjects and for elite athletes maximal tests would disrupt training load balance.
What is a submaximal fitness test?
The submaximal aerobic fitness test is
a graded exercise test performed on a bicycle
. This test will give you an accurate estimate of your aerobic fitness level, allowing you to compare your cardiovascular fitness to others in your age group.
What is the purpose of the submaximal test?
Purpose: Submaximal aerobic exercise testing is
utilized with a variety of populations to assess fitness level and predict maximal oxygen uptake (VO2peak) when a maximal test is not possible or preferable
.
What is an example of a submaximal test?
Studies were required to have assessed the psychometric properties of any of the following submaximal exercise tests to be eligible: Åstrand test; modified Åstrand test;
Lean body mass-based Åstrand test
; submaximal bicycle ergometer test following a protocol other than the Åstrand test; 2-km walk test; shuttle walk …
What assumptions are made when using a submaximal test?
Heart rate is allowed to reach steady
-state at each stage of the test. The age-predicted maximal HR is uniform (220 J age) with a prediction error of 10% to 15%. A linear relationship exists between HR and oxygen uptake. Mechanical efficiency is the same for everyone (e.g., VO2 at a given work rate).
What are disadvantages of submaximal testing?
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.
What does submaximal mean?
:
less than maximal
: not at the greatest or highest possible level submaximal exertion One hundred twenty asymptomatic patients underwent a submaximal treadmill exercise test two to three weeks after an acute myocardial infarction. — JAMA.
What are two advantages to utilizing a submaximal test?
Submaximal exercise tests can be used to predict V̇o
2
max,
to make diagnoses and assess functional limitations
, to assess the outcome of interventions such as exercise programs, to measure the effects of pharmacological agents, and to examine the effect of recovery strategies on exercise performance.
When do you stop submaximal testing?
Test termination criteria
In addition, any exercise test intended to be classified as a “submaximal” exercise test should be stopped
when a heart rate of 85% of age-adjusted maximal heart rate (AAMHR)
is achieved as per definition of “submaximal” by ACSM guidelines.
When should you terminate a workout?
Indications for terminating the test include if the patient request to stop due to severe symptoms (i.e., chest pain, shortness of breath or fatigue),
severe exercise-induced hypotension or hypertension
, horizontal or downsloping ST depression of greater than or equal to 1 mm or ST-segment elevation, new bundle branch …
What is the step test?
The Step Test is
designed to measure a person’s aerobic fitness
. Participants step up and down, on and off an aerobics- type step for THREE minutes to increase heart rate and to evaluate the heart’s recovery rate during the minute immediately following the step test exercise.
What are the 4 modes of exercise testing?
Maximal test
(exercise stress test; EST) Cardiopulmonary exercise test (CPET) Submaximal test (six-minute walk test; 6MWT) Submaximal treadmill test.
What is vox2?
VO2 max refers to
the maximum amount of oxygen you can utilize during exercise
. … VO2 max is measured in milliliters of oxygen consumed in one minute, per kilogram of body weight (mL/kg/min).
What is the Astrand cycle test?
The Astrand-Rhyming cycle ergometer test (ARCET) is
a commonly administered submaximal test for estimating aerobic capacity
. Whereas typically utilized in clinical populations, the validity of the ARCET to predict VO
2max
in a non-clinical population, especially female, is less clear.
What is modified Bruce protocol?
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. This protocol it is most often used in older individuals or those whose exercise capacity is limited by cardiac disease.
What is a maximal test?
A maximal exercise test is one that
is performed with progressively increasing workloads up to limiting fatigue and/
or dyspnea caused by exhaustion of the capacity for adaptation of the patient’s cardiovascular system.
