# Question: cycle on a mechanically braked arm cycle ergometer for 5...

###### Question details

Cycle on a *mechanically*
braked **arm cycle** ergometer for 5 minutes with a
load of 1.25 kp and a metronome setting of 50 revolutions /min.
Assume that the oxygen cost for this work was 20.5 ml/kg/min. Also
assume that your resting energy expenditure is 1 Met (i.e., 3.5
ml/kg/min).

Determine your
*Gross**Mechanical Efficiency* and
*NET Mechanical Efficiency* for this exercise.

Hint: first determine kpM/min;
then change exercise and resting VO_{2}ml/kg/mininto
ml/minthen into kcal/min; (Note: 200 ml O2 = 1
kcal);
