About this study

Official title: Effect of a Customized Occlusal Splint on Athletic Performance in Master Swimmers: A Randomized Pilot Clinical Trial

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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

    Measured: Measurements were taken during the training sessions, in day 1

Secondary outcomes (1)
  1. Stroke efficiency

    Stroke efficiency was measured as the number of strokes per 25 meters, determined by direct observation and manual counting by two externals observers

    Measured: Measurements were taken during the training sessions, in day 1

Model description
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.

Questions about this trial

What is this clinical trial studying?

A study testing occlusal splint in people with 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 and Athletic Performance and the Impact on Performance Factors, run by Universidad Europea de Valencia at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

swimming performance (time frame: Measurements were taken during the training sessions, in day 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2026.
