What would be Ms. F's target workload on a leg cycle ergometer at 50% of VO2R?
Explanation / Answer
Formula of VO2R of leg cycle ergometer is,
VO2R= 1.8 ( work rate) /(BM) + 3.5+3.
27mg/dL = 1.8 (work rate) / (142)+3.5 + 3.5
27mg/dL = 1.8 × work rate / 142 + 7
work rate = 1.8 ×27 /142 +7
= 48.6 / 142 + 7
= 0.34+ 7
= 7.34 × 0.50( as rate of VO2R is 50%)
= 3.67 ml/ kg/ min.
