YMCA Cycle Ergometer Submaximal Test Questions and Answers Graded A

YMCA Cycle Ergometer Submaximal Test Questions and Answers Graded A What is the YMCA cycle erg test? A submaximal test on a cycle ergometer used to estimate VO2max. Goal: To raise HR within 10bpm of 85% of age-predicted HR max by the end of the test (test terminates when this has been achieved, record the workload in which this was achieved) with each subsequent workload, power increases by 25W Step 1 Greet the Client - ensure they have a signed ParQ Step 2 Pre-Test Responsibilities - HR: a) Calculate 85% of age predicted HR max b) prepare HR monitor by wetting the band and asking the participant to place it below their nipple line. Sync HR monitor to the bike. Step 3 Pre-Test Responsibilities - Preamble/bike set up: a) Adjust seat height: - knee bent at 5 degrees, approx, hip height, at bottom of stroke with neutral foot. *ensure pedaling position is comfortable for the subject c) explain criteria for stopping: i) if subject feels dizzy or short of breath ii) if subject wants to end the test iii) if SSHR is within 10bpm of 85% age predicted HR max in the last minute of any stage Step 4 In-Test Responsibilities - Workload 1: duration: 3:00 minutes Work rate: 25W (150kpm/min) a) CSEP suggests a cadence of 50rpm as their bikes are preloaded with 0.5kp of resistance. However, since monarch bikes are automatically loaded with 1kg of resistance, workload 1 needs to be at 25rpm to achieve 25W Power (kpm/min) = 1kp x 25 x6 Power = 150kpm/min b) identify HR in the last 15 secs of each minute c) measure RPE in the last 15 secs of each stage (i.e., minute 3, or minute 4 if it goes to minute 4) d) determine if SSHR has been achieved: that is, whether the difference in HR between minute 2 and minute 3 is less than or equal too 5bpm. if it is 5bpm, continue for a 4th minute. e) if SSHR has been achieved, progress to the next workload in function of HR during the last minute of the initial workload. Step 5 In-Test Responsibilities - Workloads 2 and on: duration: 3:00 minutes rpm: 50 - identify HR in last 15secs of each minute - determine if SSHR has been reached based on last 2 HR of stage - Measure RPE in last 15secs of each stage a) correctly adjust weight resistance b) correctly identify whether SSHR has been reached and adjust/don't adjust accordingly *once min 3/4 HR is within 10bpm of 85% HR max test is complete Step 6 Post-Test Responsibilities - Active Recovery : a) remove resistance b) have participant cycle at a work rate equivalent or lower to the first stage after ~3-5 minutes ask participant if they feel sufficiently recovered, if yes, move on Step 7 Post-Test Responsibilities - Passive Recovery: - move participant to seated position - if after 3mins HR 100bpm, recovery is over Step 8 Calculate the estimated VO2 max & record associated health benefit rating: Estimated VO2max = SM2 + [b(HRmax-HR2)] Slope (b) = (SM2 - SM1) / (HR2 - HR1) submax VO2 = [(workload in W / body mass in kg) x 10.8] + 7.0 SM2 = Sub-maximal VO2 at last workload SM1 = Sub-max VO2 at 2nd last workload HR2 = Average of last two heart rates from last workload HR1 = Average of last two HRs from the 2nd last workload
