Gas exchange responses to ramp exercise.
In the present study, the system of oxygen uptake (VO2) during ramp function exercise protocol can be studied to provide information about the physiological mechanisms underlying the process. The values of maximal oxygen uptake (VO2max) and gas exchange threshold (GET) were reproducibly obtained using ramp test protocol. On the other hand, the determination of VO2/work rate should be restrict to below the exercise intensity of the GET. Therefore, ramp exercise test might be usage for determination of VO2max, GET and/or VO2/work rate (i.e., work efficiency). The data obtained in this study concerning the mean response time (MRT) suggests that the ramp test is not a linear, first-order system. Therefore, the ramp exercise test protocol is recommended for the determination of VO2max, GET and work efficiency, but not for MRT.
