In most sports, mobility of the body's center of mass is as important as muscle strength and posture maintenance. Many dynamic studies have revealed a positive relationship between teeth clenching with a mouthguard (CLMG) and athletic ability. However, the effects of CLMG on mobility remain controversial. Vertical jumping, particularly squat jumping (SJ), can be used to evaluate this ability. During SJ, arm swing and reactionary operation of lower limbs are limited. Therefore, the effects of CLMG can be readily investigated. In the present study, we measured SJ height, biomechanics data and masseter muscle activity under two oral conditions: CLMG, and no mouthguard with no instructions on clenching. The aim of the present study was to clarify whether CLMG improves SJ performance. A total of 10 adult female athletes with an average age of 20.8±1.2 years participated in this study. The study protocol was approved by the Tokyo Dental College Ethics Committee (approval No. 437). The study adhered to the tenets of the Helsinki Declaration on the Ethical Treatment of Human Subjects. A customized EVA MG was used for each subject. Measuring devices included the 3-dimensional motion capture system, ground reaction force meters, and electromyograms. The results indicated that CLMG improved SJ height by enhancing work, work rate of hip joints, steadiness of body balance function during jump preparation, and masseter muscle activity. Within the limitations of this study, the results indicated that CLMG tended to improve SJ performance. [ABSTRACT FROM AUTHOR] |
