Abstract/OtherAbstract:
OBJECTIVE: : To test the hypothesis that 2 types of custom-made mouthguards will have no effect on ventilation (&OV0312;E, L·min), oxygen uptake (&OV0312;O2, mL·kg·min·), and heart rate (beats per minutes) at varying exercise intensities (10 km·h and 12 km·h) and at subjective maximal effort (&OV0312;O2peak) in male field hockey and water polo players.
DESIGN: : A randomized, prospective, crossover study.
SETTING: : The Physiology Testing Laboratory, School of Sports Science, Exercise and Health at the University of Western Australia, a tertiary educational institution.
PARTICIPANTS: : Twenty-seven male team-sport athletes.
INTERVENTIONS: : Each athlete participated in 3 experimental exercise sessions separated by 1-week intervals. Testing involved a graded exercise test (GXT) performed on a treadmill wearing either a custom laminated mouthguard with normal palatal surface, a custom laminated mouthguard with palatal coverage up to the gingival margin, or no mouthguard. The experimental trials were performed in a random counterbalanced order.
MAIN OUTCOME MEASURES: : &OV0312;E (L·min) and &OV0312;O2 (mL·kg·min) were measured during the GXT at intensities that equated to 10 km·h, 12 km·h and subjective maximal effort (&OV0312;O2peak).
RESULTS: : There were no significant differences between trials for &OV0312;E (L·min) and &OV0312;O2 (mL·kg·min) at any of the intensities assessed (P < 0.05).
CONCLUSIONS: : The wearing of 2 different custom-made mouthguards during a GXT did not impair &OV0312;E or &OV0312;O2 during varying levels of exercise intensity in team sport athletes.
