Question
Vertical Jump height is primarily dependent on which system?
A. Creatine phosphate
B.Anaerobic Glycolysis
C. Aerobic metabolism
Two people of different body mass jump the same height. Which subjects has a higher relative power output?
A. The heavier subject
B. The lighter subject
C. They are the same
D. Cant determine from information given
WHich of the following is TRUE about minute ventilation
A. The correct units are L/min
B. It equals respiratory rate multiplied by tidal volume
C. Both
D. Neither
True or False: Residual volume can be measured with spirometry
Explanation / Answer
1) Vertical jump is a short term intense activity. The energy for this has to be supplied very quickly. Phosphagen system comes to rescue in this scenario, to supply ATP from creatine phosphate stored in muscles. This is an anaerobic system and undergoes fatiguability easily. So, the answer for this question is option A (creatine phosphate).
2) When two people with different body mass jump the same height, the heavier subject will have the higher relative power output.
3) Minute ventilation is defined as the amount of air breathed in and out by the individual per minute. It is the product of respiratory rate and tidal volume. It is usually expressed in liters per minute. So, the answer for this question is option C.
4) Residual volume is the amount of air present in the lungs after forced expiration. It cannot be measured by using spirometry. So, the given statement is false.
