Q:

A college-aged, female has a VO2max of 52 ml/kg/min & her body mass is 122 lbs; We set the exercise intensity at 65% VO2max & the duration of the exercise at 35 min. 1. What is her MET capacity/max? 2. How many METs will she be exercising at? 3. Is this considered Light, Moderate, or Vigorous activity? 4. How many MET'min will she accumulate over the exercise period? 5. If she does this exercise routine 3 times per week, how many MET min/week will she accumulate?

Accepted Solution

A:
Answer:1) MET capacity/max = 14.857 MET2) METs she is exercising at = 9.657 MET3) vigorous activity4) 338 MET*min5) 1014 MET*min/week Step-by-step explanation:Given:VO2 max = 52 ml/kg/minbody mass = 122 lbsexercise intensity = 65% VO2maxDuration of the exercise = 35 min1) Now, 1 MET = 3.5 ml/kg/minThus, Her  MET capacity/max = [tex]\frac{\textup{VO2 max}}{\textup{1 MET}}[/tex] orHer  MET capacity/max = [tex]\frac{\textup{52 ml/kg/min}}{\textup{3.5 ml/kg/min}}[/tex] orHer  MET capacity/max = 14.857 MET2) METs she is exercising at = exercise intensity × MET capacity/maxorMETs she is exercising at = 0.65 × 14.857 METorMETs she is exercising at = 9.657 MET3) Her MET = 9.657  which is greater than 6, thus it will be considered as vigorous activity4) MET*min she accumulated over the exercise period= METs she is exercising at × Duration of the exercise= 9.657 × 35= 338 MET*min5) Now,exercise routine = 3 times per weekthus,MET min/week she accumulate = exercise routine × MET*min she accumulated= 3 × 338= 1014 MET*min/week
