Question

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?

Answer 1

Answer:

1) MET capacity/max = 14.857 MET

2) METs she is exercising at = 9.657 MET

3) vigorous activity

4) 338 MET*min

5) 1014 MET*min/week

Step-by-step explanation:

Given:

VO2 max = 52 ml/kg/min

body mass = 122 lbs

exercise intensity = 65% VO2max

Duration of the exercise = 35 min

1) Now,

1 MET = 3.5 ml/kg/min

Thus,

Her  MET capacity/max = $\frac{\textup{VO2 max}}{\textup{1 MET}}$

or

Her  MET capacity/max = $\frac{\textup{52 ml/kg/min}}{\textup{3.5 ml/kg/min}}$

or

Her  MET capacity/max = 14.857 MET

2) METs she is exercising at = exercise intensity × MET capacity/max

or

METs she is exercising at = 0.65 × 14.857 MET

or

METs she is exercising at = 9.657 MET

3) Her MET = 9.657  which is greater than 6, thus it will be considered as vigorous activity

4) MET*min she accumulated over the exercise period

= METs she is exercising at × Duration of the exercise

= 9.657 × 35

= 338 MET*min

5) Now,

exercise routine = 3 times per week

thus,

MET min/week she accumulate

= exercise routine × MET*min she accumulated

= 3 × 338

= 1014 MET*min/week
