Textbook Problem

A woman jogging has a metabolic rate of 625 W. (a) Calculate her volume rate of oxygen consumption in L/s. (b) Estimate her required respiratory rate in breaths/min if her lungs inhale 0.600 L of air in each breath and air is 20.9% oxygen.

(a)

To determine
The volume rate of oxygen consumption in L/s.

Explanation

Given Info:

The metabolic rate of the women is625W.

Formula to the volume rate of oxygen consumption in L/s,

ΔVO2Δt=14.8ΔUΔt

  • ΔUΔt is the metabolic rate in kcal/s

Substitute 625W for ΔUΔt to find the rate of oxygen consumption,

ΔVO2Δt=14

(b)

To determine
the required respiratory rate in breaths/min.
