/ Questions
14. Measurement of VO2 max can be performed using either the arms or the legs.
15. VO2 max is the best predictor of performance in endurance events for trained runners.
16. The vertical jump test uses the ATP-PC system, so it is considered a good predictor of success in running a short (40-100 yards) dash.
17. Lactate threshold can be used to predict the estimated finish time in a race.
18. A more economical runner will have a higher VO2 at a given speed than with an uneconomical runner.
