The Effect of Mouthguard Design on Respiratory Function in Athletes.

The article presents a randomized crossover study on the effects of mouthguards to the oxygen uptake during incremental exercise test. The study examines the hypothesis that mouthguards would not affect ventilation at different exercise intensities. The study used the graded exercise test (GXT) accomplished by the players with or without a mouthguard. The study indicates that there is no observed significant differences on the performance of the athletes during the experimental trials.
