1. The problem statement, all variables and given/known data Alright, so I am a graduating senior studying Exercise science and physiology. I just had what we call "Client Testing" and ran my client (who was a collegiate athlete for the last four years and this year was her first year not competing or training) in the Bruce protocol for a maximal exercise test. The test went well, but when I was able to finally look at the metabolic print out that my group-mate was working, she only had a VO2 max (according to the sheet) of 29.7 mL/kg/min. I thought that was strange, it should be a lot higher as she was conditioned. After Graphing the data and trying to find VT and RCP, it is evident that she did not reach VO2 max, though she did look as if she was doing total body exertion. So, My question is, can I use my data as if she had run a submaximal test? She ended on the end of stage four and I know that protocol says to only use three stages, but since she is conditioned and an athlete, I was wondering how to go about getting a better estimate for VO2 max. 2. Relevant equations Volleyball player 22 years of age 5'4" (163 cm) 59 kg Vo2Max of 29.7 (as per testing data) Max heart rate: 192 Resting heart rate: 66 resting BP: 110/67 Ending BP: 183/84 EKG normal findings 3. The attempt at a solution So, My question is, can I use my data as if she had run a submaximal test? She ended on the end of stage four and I know that protocol says to only use three stages, but since she is conditioned and an athlete. IF i were to treat this as a submaximal test to make a better estimation and I would plot VO2 vs heart rate for each minute and continue the line, stopping at her max heart rate and assuming that that is the maximal VO2. Would that still be a plausible explanation and use the first three stages? Thanks so much for your help!
