520 $a In summary, this dissertation concludes that oxygen uptake kinetics (gas exchange dynamics) may have the potential to serve as a sensitive overall indicator of cardiorespiratory and muscular adaptation.
520 $a Three separate studies investigated oxygen uptake kinetics for measurement reliability, monitoring of training adaptation in endurance athletes, and potential performance enhancing effects of Salbutamol.
520 $a The reliability study produced a reliability estimate of 0.9 for the time constant measures via a submaximal cycling protocol. This demonstrated an adequate level of reliability and provided the basis for the next two studies. The second study took 16 competitive cyclists through a carefully controlled eight week endurance cycling program. VO$\sb2 $m ax, transient oxygen uptake kinetics, and 40k time trial tests occurred five times (3 times pre-training, once at the midpoint, and once post-training). The transient protocol consisted of three equal ascending submaximal transitions with blood samples drawn at each stage for analysis of lactate concentration. The general trend, as the trained state of the cyclists rose, was for faster oxygen uptake time constants, lower blood lactate concentrations, higher VO$\sb2 $m ax scores, and faster 40k time trial results. Overall, these results are supported by the literature and suggest that a combination of central and peripheral components are responsible for the time course of oxygen uptake. It was concluded that VO$\sb2$ kinetics are relatively sensitive to endurance training adaptation, although, further investigation is required to clearly describe the underlying mechanism(s).
520 $a The third investigation used a submaximal oxygen uptake kinetics task, VO$\sb2 $m ax cycling, pulmonary function tasks, a 60 second supramaximal sprint test, and a simulated 20k time trial to examine the possible ergogenic effect of Salbutamol on a group of cyclists. Fifteen trained nonasthmatic male cyclists were recruited into a double-blind, randomized cross-over design using a dosage of Salbutamol twice the normal therapeutic level (400$\mu $g ). Subjects performed four tests, separated by 48 hours, in each condition (placebo or Salbutamol). No significant differences were observed in any of the dependent variables, leading to the conclusion that Salbutamol has no performance enhancing properties as determined by the protocols adopted in this study.
