Question

Exercise & Science Major --- Calculations for the Astrand Cycler Ergometer Test

Given numbers:

Ending Workload - 2.5

Sex - Male 21 years old

Body Weight in Kg - 70.1kg

1. Convert the ending workload from kp to kg/mmin.

1 kp = 300 kg/m/min

2.5 kp = 750 kg/m/min (Answered Already)

2. Determine the VO2submax of the workload at the end of test.

VO2submax [mL/kg/min] = ending workload [kg/m/min] x 1.8 / body weight [kg] +7

Determine sex code.

Women = 0

Men = 1

3. Determine the age predicted maximal heart rate (APMHR).

APMHR = 220 – Age

199 = 220-21(Answered already)

4. Determine end of trial stead state heart rate (HRss).

Average of the 2 heart rates measured during the last 2 minutes of exercise

116 + 114 = 115 HR (answered already)

5. Determine the estimated VO2max.

Formula Given - VO2max (mL/kg/min) = VO2submax [mL/kg/min] x (APMHR – 73 – (Sex Code x 10)) / (HRss – 73 – (Sex Code x 10))

2.Determine the VO2submax of the workload at the end of test.

VO2submax [mL/kg/min] = ending workload [kg/m/min] x 1.8 / body weight [kg] +7

VO2submax= 750 kg/m/min x 1.8/ 70.1 kg + 7

= 26.25 ml/kg/min

---------------------------------------------------------------------------------------------------------------------------------------------------

5. Determine the estimated VO2max.

VO2max (mL/kg/min) = VO2submax [mL/kg/min] x (APMHR – 73 – (Sex Code x 10)) / (HRss – 73 – (Sex Code x 10))

vo2 submax = 26.25 ml/kg/min

APMHR = 199

sex code = 1

HRss = 115 HR

VO2max = 26.25 * (199-73 -(1*10)) / (115-73 - (1*10))

= 95.15 ml/kg/min
