The aim of the study was to determine whether choosing a %TS corresponds to the physiological concept of relative exercise intensity (% peak oxygen uptake: %VO2 peak) and to examine selected physiological and metabolic responses of a group of wheelchair athletes to 60 minutes' exercise at 80% TS. METHODS: 12 male wheelchair athletes (10 paraplegics and two tetraplegics) performed a series of tests on a motorised treadmill adapted for wheelchairs. The tests, which were undertaken on separate occasions, included the determination of VO2 peak, the determination of oxygen cost at a range of submaximal wheelchair propulsion speeds, and a 60 min exercise test at 80% TS. RESULTS: Wheelchair propulsion speeds equivalent to 60%, 70%, 80%, and 90% of each subject's TS were found to equate to 48.3 (SD13.8)%, 60.0(11.1)%, 70.6(9.8)%, and 82.7(9.6)% of VO2 peak, with a wide variation in the relative exercise intensities evident at each %TS. During the 1 h exercise test at 80% TS the physiological and metabolic responses measured were indicative of steady state exercise, with no signs of fatigue evident. CONCLUSIONS: The results of this study suggest that selecting a %TS is not an appropriate way of selecting a common relative exercise intensity. There may also be a need for the current training practises of some wheelchair road racers to be modified.<\/jats:p>","DOI":"10.1136\/bjsm.31.1.36","type":"journal-article","created":{"date-parts":[[2008,12,15]],"date-time":"2008-12-15T19:55:24Z","timestamp":1229370924000},"page":"36-40","source":"Crossref","is-referenced-by-count":14,"title":["Physiological responses of wheelchair athletes at percentages of top speed."],"prefix":"10.1136","volume":"31","author":[{"given":"I G","family":"Campbell","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Williams","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H K","family":"Lakomy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1997,3,1]]},"reference":[{"key":"ref_1","article-title":"The influence of level of spinal cord injury on the physiological and metabolic responses of wheelchair athletes to exercise and performance","author":"Campbell, I.G.","year":"1992","unstructured":"Campbell IG.
