You have just completed VO2 testing for your new client. Your client has displayed an anterior pelvic tilt during previous assessments. Based on their score, according to NASM, they are categorized as “Fair”.
Based on this category: What heart rate/training zone should they be working in (provide percentages)? In what stage of training will you place your client?
If the VO2 assessment includes a printout of the VO2/VCO2 values with increasing intensity, I would determine the heart rate that is coincident with the breakpoint of the VO2/VCO2 values, where VCO2 begins to increase more rapidly than VO2. This should be a good estimation of the ventilation threshold, where the anaerobic energy systems begins to kick into high gear, leading to quick fatigue.
Because of the estimation of a “fair” level of cardiovascular fitness, I recommend that the client do intervals up to the HR at threshold, then slow down to 20-25 bpm lower the the threshold HR, then speed up to threshold HR. So, rather than using percentages, I would use HR values based on he VO2 assessment. If the fitness level is fair, then the client is in the early stages of training. To measure improvement, periodically repeat exactly the same testing protocal initially used, and determine the HR at threshold. If you’re using a treadmill, you can determine changes in speed and/or grade at which the threshold HR is reached.
If there is anterior pelvic tilt, include in the client’s training programs exercises that resist posterior tilt, such as supine reverse trunk curls, the hips flexed at a constant 90 degrees.
