“…It is suggested that these motor activities contribute to the facilitation of human motor system excitability [5,6,12], which increases the neural drive to the distal muscles [13,14] in a manner similar to the Jendrassik manoeuvre [15].…”

“…Procedures Th e experimental model of the CAP modifi ed swimming start has been elaborated upon based on the outcomes of previous studies [3][4][5], and taking into account our experience in start technique investigation in Olympic swimmers [9]. Th e technique protocol included teeth clenching and voluntary contraction of abdominal muscles, which were initiated immediately aft er the preliminary starting command ("take your marks").…”

“…Furthermore, a number of studies evaluated the potentiation eff ect of RVC combined with the performance of various speed-strength exercises, termed Concurrent Activation Potentiation (CAP) [2]. Th us, a signifi cant ergogenic eff ect of CAP has been found during the performance of the high jump, squat jump, back squat, and knee fl exion and extension [3][4][5]. Th ese publications reported gains of maximal force, rate force development, and jump height that varied within 4.2-32.2% depending on the character of the variables and experimental conditions.…”

Concurrent activation potentiation (CAP) is recently developed method for enhancing athletic performance in speed-strength exercises. Th is phenomenon is based on the stimulatory eff ect of the voluntary contraction of remote muscles, which facilitates activation of prime movers and synergists for targeted exercise. Physiological prerequisites for this ergogenic eff ect are associated with the integrative function of the cerebral motor cortex and increased excitability of spinal motor neurons. Th e present study was aimed at evaluating the ergogenic eff ect producing by CAP treatment on the performance of the race start in competitive swimming. Th e CAP modifi ed start technique presupposed the teeth clenching and voluntary contraction of abdominal muscles aft er the preliminary starting command. Eight elite and sub-elite swimmers executed four crawl stroke starts: two CAP modifi ed and two conventional trials with objective registration of start reaction and time to complete a 15-m segment. Statistical analysis included a repeated measures two-way ANOVA test and size eff ect. Both the p-value and d-value between experimental and control sets were calculated. Th e average benefi t of the CAP modifi ed technique was equal to 0.08 s, which includes an advantage in start reaction equal to 0.05 s. As a result, application of the CAP modifi ed technique to swimming race start resulted in a signifi cant ergogenic eff ect, which was evaluated by start reaction and performance time on the 15-m segment of distance.

“…Des études montrent que le port d'un protège-dents de performance permet d'augmenter le PP mais aussi de l'atteindre plus rapidement et de le maintenir plus longtemps [9,17,18]. Cependant des résultats contraires ont également été publiés [19,20]. Les différences de résultats obtenus entre les études en termes d'amélioration de la résistance chez les porteurs de protège-dents soulignent l'inhomogénéité de ces études notamment parce qu'elles portent sur des exercices physiques très différents.…”

“…Plusieurs études ont confirmé l'effet neuromusculaire de l'activité motrice orale et des différentes positions de la mandibule sur le contrôle postural [50]. Des études suggèrent que l'augmentation de la force musculaire lors du serrement des dents serait la consé-quence du concurrent activation potentiation ou en français la « potentialisation par activation simultanée » qui optimiserait la commande descendante [18,19,51]. Le principe de cette potentialisation est que la force d'un muscle A devient plus importante si les muscles B (les muscles masticateurs par exemple) sont contractés en même temps.…”

Résumé -Introduction :Depuis leur apparition dans les années 1890, les protège-dents ont fait l'objet de nombreux travaux de recherche. Sur la base des résultats de ces études, le port d'un protège-dents est recommandé pour prévenir la survenue de lésions orofaciales lors de la pratique de certaines activités sportives. Depuis les années 1960, un nouveau type de protège-dents est apparu : le protège-dents de performance. Selon ses concepteurs et ses fabricants, ce dispositif permet notamment d'améliorer l'endurance, la force, la puissance musculaire, le temps de réaction, l'amplitude et la précision des mouvements, les capacités de récupération, la proprioception et de diminuer la fatigue et le stress. Revue de la littérature : Une revue de 50 ans de recherches relatives au protège-dents de performance met en évidence des résultats contradictoires. Ce constat est la conséquence de l'inhomogénéité des études qui portent sur des protège-dents, des paramètres physiologiques et biologiques, des groupes musculaires différents, des activités sportives différentes. Conclusion : Actuellement, l'amélioration des performances par le port d'un protège-dents est une hypothèse. Cependant, les essais cliniques contrôlés randomisés les plus récents tendent à la valider. L'harmonisation des protocoles de recherche pourrait donc permettre de transformer cette hypothèse en certitude dans les années à venir.Abstract -Potential of mouthguards for enhancing sport and physical performances: a review of 50 years of medical research. Introduction: Since their appearance in the 1890s, mouthguards have been the subject of numerous research studies. Based on the results of these studies, the use of mouthguard is recommended for the prevention of orofacial lesions in some sports. Since the mid-1960, a new type of mouthguard appeared: the performance mouthguard. According to its manufacturers and creators, this appliance particularly enables to improve endurance, strength, muscular power, reaction time, precision of movements, recovery capacity, range of motion, concentration and proprioception, and to decrease fatigue and stress. Literature review: A review of 50 years of medical research on performance mouthguards shows contradictory results. This reflects the inhomogeneity of studies which focus on different mouthguards, parameters recorded, muscular groups and sports. Conclusion: At the moment, the enhancement of performance by using a mouthguard is an assumption. However, the latest blinded controlled clinical trials tend to validate this assumption. Harmonization of research protocols would allow this assumption to become evidence.
