@article { , title = {Adding intermittent vibration to varied-intensity work intervals: no extra benefit}, abstract = {Varied-intensity work intervals have been shown to induce higher fractions of maximal oxygen uptake during high-intensity interval training compared with constant-intensity work intervals. We assessed whether varied-intensity work intervals combined with intermittent vibration could further increase cyclists’ fraction of maximal oxygen uptake to potentially optimise adaptive stimulus. Thirteen cyclists (V̇O2max: 69.7±7.1 ml·kg-1·min-1) underwent a performance assessment and two high-intensity interval training sessions. Both comprised six 5-minute varied-intensity work intervals within which work rate was alternated between 100\% (3x30-second blocks, with or without vibration) and 77\% of maximal aerobic power (always without vibration). Adding vibration to varied-intensity work intervals did not elicit longer time above ninety percent of maximal oxygen uptake (415±221 versus 399±209 seconds, P=0.69). Heart rate- and perceptual-based training-load metrics were also not affected (all P≥0.59). When considering individual work intervals, no between-condition differences were found (fraction of maximal oxygen uptake, P=0.34; total oxygen uptake, P=0.053; mean minute ventilation, P=0.079; mean heart rate, P=0.88; blood lactate concentration, P=0.53; ratings of perceived exertion, P=0.29). Adding intermittent vibration to varied-intensity work intervals does not increase the fraction of maximal oxygen uptake elicited. Whether intermittent exposure to vibration can enhance cyclists’ adaptive stimulus triggered by high-intensity interval training remains to be determined.}, doi = {10.1055/a-1812-7600}, eissn = {1439-3964}, issn = {0172-4622}, issue = {02}, journal = {International Journal of Sports Medicine}, pages = {126-132}, publicationstatus = {Published}, publisher = {Thieme Publishing}, url = {http://researchrepository.napier.ac.uk/Output/2896864}, volume = {44}, keyword = {vibration training, athletic performance, physiological responses, elite cycling, physical conditioning, exercise tolerance}, year = {2024}, author = {Bossi, Arthur Henrique and Mesquida, Cristian and Hopker, James and Rønnestad, Bent} }
