abstract = {Background/objectives: The potential advantages of wearing customized bite-aligning mouthguards on
several performance parameters such as muscular strength, power and reaction time have been reported.
Literature shows that the concurrent activation potentiation phenomenon, elicited by a powered and
balanced jaw clenching, can provide athletes with several neuromuscular advantages. The aim of the
present study was to investigate the acute effects of jaw clenching while wearing a customized bitealigning
mouthguard on swimming start, countermovement jump and swim bench test, in contrast to
two other conditions: non-jaw clenching and jaw clenching without mouthguard.
Methods: A randomized, repeated measure within study designwas used to compare the condition effect
on eight highly trained elite male and female swimmers.
Results: Statistical analysis revealed a significant increase in the countermovement jump height
(p ¼ 0.041) when comparing the use of mouthguards with the non-jaw condition. In the swim bench, a
significant greater time to peak force (p ¼ 0.049) was found when comparing the use of mouthguards
with the jaw condition. Although, non-significant effects, small differences were found in the start reaction
time and 15-m freestyle swimming when comparing the use of mouthguards with the non-jaw
condition.
Conclusion: This study demonstrated that wearing customized, bite-aligning mouthguards had an ergogenic
effect on specific measures of vertical jump and swim bench test, whereas non-meaningful but
small differences were found in swimming start.},
