Submax exs testing Flashcards
submaximal exercise testing definition
one that requires the client to perform a fixed amount of work per unit of time
what is a submax test used for?
estimating VO2max
What are submax tests decisions are based on
reason for test, type of subject being tested, availability of equipment and personal, risk strat
Maximal exs test are more useful where
clinically aiding in diagnosis of CAD in asymptomatic patients
max exs esting not feasible for
assessing CV endurance for vast majority of health/fitness practitioners
What is the purpose of YMCA bike ergometer lab?
A cycle ergometer submax protocol for women and men was developed in 1989 (Goldings, Meyers, and sinning). This submaximal test uses 3 to 4 consecutive stages/workloads on the cycle ergometer with the intent to elevate heart rate to 110 bpm and 85% of one’s age-predicted HRmax for at least 2 consecutive workloads. The ensuing results are used to predict VO2max based on the assumption that HR and oxygen consumption are linear f(x) of work rate.
What is being assessed and recorded on data sheet for lab 5 before starting test?
resting bp and HR
What is the pedal rate for lab 5 and initial workload?
50 rev/min (set metronome to 50- 100) and the initial workload is 150kgm/min which is 25 watts or 0.5kg
When is HR measured during this ymca submax bike test?
Measure HR during the last 30 seconds of minutes 2 and 3 at each workload
What do you do if the HR varies more than blank?
IF these HRs vary by more than 5-6bpm continue the same workload for an additional minute until heart rate stabilizes
When is RPE and BP determined?
Determine the RPE and BP during the third minute of each workload.
When is BP measured?
Measure BP once per stage btwn the 2 HR measurements
When is RPE measured?
Measure rating of perceived exertion (RPE) during the last 10-15 seconds of each stage, after taking 2nd HR
How do you determine workload after first stage for YMCA protocol on leg ergometer?
Use the HR from last minute of the first workload/stage to determine the second and subsequent workloads
If HR is less than 80 bpm, set second workload to what?
750 kgm/min = 2.5 kg
If HR is 80-89 bpm, set second workload to what?
600 kgm/min =2kg
If HR is 90-100 bpm, set second workload to ?
450 kgm/min = 1.5 kg
If HR is greater than 100 BPM, set second workload to ?
300 kgm/min = 1 kg
How do you know when to terminate the test for lab 5?
IF the subject’s steady state HR exceeds 85% of the age-predicted HRmax during the third stage
Upon reaching 85% age-predicted HRmax, reduce workload ?
150 kgm/min (.5 kg) for 2 minutes and record the HR and BP during the last 30 seconds of the second minute
What is being calculated for lab 5 and for what?
calculate energy expenditure (VO2) for last 2 workloads
How is VO2 max determined from lab 5?
determine the M of HR vs workload relationship by plotting steady state HRs to last 2 workloads and connect these 2 data points with straight edge, extending the line so that it intersects the predicted HRmax line.
When is steady state HR obtained in submax testing?
Steady state HR is obtained for ea exs work rate
What kind of relationship exist btwn HR and O2 uptake?
a linear relationship
HRmax at given age is
uniform
Mechanial efficiency is the blank
same for everyone, but different for trained people
Traditional Method for measuring HRmax (FOX eqn)
220-age=HRmax +/- 10bpm
Gellish eqn for HRmax
206.9-(0.67x age)= HRmax +/- 2bpm
Tanaka eqn for HRmax
208-(0.7xage)=HRmax
Londeree & Moeschberger eqn
206-(.7age)=HR max
