Objective: Collecting data of VO2 max and power test for the subject.
Subject: 167 lb, 6 ft, 52 years old. Methodology and Material: We used metabolic cart, mask and tubes to detect oxygen consumption for determining VO2 max of the subject. Compute Trainer and the software Racermate were also used with the bike to measure the power output of the subject. First, we ran calibration test for the bike with Racermate, and calibration test for the metabolic cart. Meanwhile, gas test was operated on the metabolic cart. We chose the Male20min training program for the subject, which includes about 8 minutes of warm up and 12 minutes of ascending speed and power input demand. Then, the subject wore the mask and had the tube on the mask attached to the metabolic cart sensor, starting to cycle with the program chosen. The R value of the subject has to be greater than 1.10, representing the real effort that the subject puts in. Besides, we decided on two ways that could identify the VO2 max for the subject. One is if the subject can no longer maintain 90 RPM on the bike; the other one is that if the VO2 measurement is not increasing by 2 mL/min/kg at one-minute interval, since VO2 max is determined over one-minute interval. Data: We chose to have the data be sorted in 15 seconds for one interval. The subject's VO2 max is at 15 minutes, with 55.15 mL/min/kg and 325 watts power input. Future trials: For the future trials, the subject will cycle at 95% of his VO2 max to ascertain the fatigue time of the subject. The project will be a blind test that the subject is given unknown tea to drink one hour before testing, excluding psychological effects. Conclusion: The internship went really well today and we got some wonderful data, so next week we will start our familiarisation trial.
