breathlessness, fatigue
Running elicited a higher Given the greater capacity and requirement for oxygen consumption during running, absolute mean Time spent at > 90% While understanding the The higher reported breathlessness (dRPE-B) for running probably reflected the higher metabolic demand and central responses (e.g., oxygen uptake, breathing rate, etc.) of this exercise modality, albeit our data were consistent with this effect being trivial to very large. Differences in favour of a higher rating of leg-exertion (dRPE-L) for cycling were more certain (small to large effects), and accompanied a greater reduction in MVC after this mode of exercise with similar certainty (small to large). Our use of dRPE therefore offered a potentially sensitive measure capable of differentiating between the specific central and peripheral inputs during HIIT (Mclaren et al. Understanding the neuromuscular response to short-duration HIIT is necessary because of the potential impact on subsequent training sessions (Leveritt and Abernethy The study is not without limitations. First, the use of male university standard team sport athletes means that our findings might not translate directly to those athletes of a higher or lower standard or to female participants. Given the task-dependent nature of fatigue (Enoka and Duchateau
