Brief Summary

Optimizing sports performance depends on the interaction of physiological, biomechanical, and neuromuscular factors. In recent years, interest has increased in the relationship between stomatognathic function and athletic performance, particularly regarding the possible role of occlusal splints in neuromuscular activation. This study evaluated the effect of a customized occlusal splint on the increase of Concurrent Activation Potentiation.

Conditions

the Aim of This Study Was to Evaluate the Effect of a Custom Occlusal Splint on Swimming Performance, Stroke Efficiency, and Heart Rate in Master Swimmers; Athletic Performance and the Impact on Performance Factors

Keywords

athletic performance and the impact on performance factors

Outcome Measures

Primary Outcomes (1)

• swimming performance

  swimming performance was quantified as pace in 100 meters and 50 meters freestyle, both measured in seconds with a digital stopwatch (SRUIS, ZSD013, France). For each participant and distance, three consecutive trials were recorded under standardized conditions, and averaged for statistical analysis

  Measurements were taken during the training sessions, in day 1

Secondary Outcomes (1)

• Stroke efficiency

  Measurements were taken during the training sessions, in day 1

Other Outcomes (2)

• Cardiovascular efficiency

  Measurements were taken during the training sessions, in day 1

• Maximum heart rate

  Measurements were taken during the training sessions, in day 1

Model Details: A randomized pilot clinical trial was conducted with 20 master swimmers, allocated to an intervention group, which used a customized occlusal splint, and a control group, which continued training without a splint. The variables analysed were 100-meter freestyle pace, 50-meter freestyle pace, number of strokes per 25 meters, and heart rate. Measurements were performed at baseline and after 88 days of follow-up. Statistical analysis included non-parametric methods, the Brunner-Langer model, the Wilcoxon test, and the Mann-Whitney U test. Statistical significance was set at p \< 0.05.
