Filter by:This study is designed to evaluate the effects of a multimodal exercise program in the sprint performance and kinematics of adolescent rugby players. For this, an experimental study with an intervention group (IG) and a control group (CG) is designed. During 6 weeks of the 2022-2023 preseason of rugby seven, IG will include a multimodal exercise program in their training routine. Meanwhile, CG will maintain their training routine. The study will be developed in the Sport High Performance Centre of Balearic Islands during the season of rugby seven (from August to September, 2022). All rugby athletes from under-16 and under-18 autonomic rugby teams will be invited to participate in this study throughout an email invitation from their regional rugby federation. Prior to the beginning of the study, all participants will sign the inform consent, or their legal tutors in case of minors. The Ethical Committee of the local university approved this study (278CER22) according to the Declaration of Helsinki. One week before intervention period, sociodemographic and sportive data will be registered (age, sex, body mass, height, and sport experience). Body mass and height will be evaluated with a ±100-g precision digital weight scale (Tefal, France) and a t201-t4 adult height scale (Asimed, Spain), respectively. Also, the rugby players will complete a familiarization process consisting on a standardized warm up and 3 progressive sprints (i.e. 30 m at 50%, 70% and 90% of maximal effort). All testing procedure (pre-test and post-test) will be completed at a similar daytime (between 17h and 19h) on the same natural grass field. The test procedure listed in our study will consist on two maximal 30-m sprints to obtain mechanical variables of horizontal force-velocity profile and kinematics during sprinting. Players from IG will perform a multimodal exercise program two days per week during six weeks. This program will include running technical drills, exercises for lumbopelvic stabilization and resisted sprints. This program will be supervised by two experts in this field. The investigators hypothesize that those rugby players who add the multimodal exercise program to their training routine will increase mechanical and kinematics variables of sprint performance.
Injuries to the lower limbs are the most common in rugby and within the lower limbs, the most common are those that affect the ligaments of the knee. That is why we will try to improve knee stability and quadriceps strength. The aim of this study is to evaluate the effectiveness of performing a pre-workout exercise protocol to improve knee stability and quadriceps strength in rugby players. Randomized controlled study, simple blind and with follow-up. 30 semi-professional rugby players will be randomized to the two study groups: experimental (pre-training exercise protocol that will include continuous running, squats, and squats and monopodal jumps) and control (without intervention). The intervention will last 4 weeks, with 2 weekly sessions of 15 minutes each. The study variables will be: knee stability (Y-Balance) and quadriceps strength (Single leg hop). The sample distribution will be calculated using the Kolmogorov-Smirnov test. The changes after each evaluation will be analyzed with the t-student test and with an ANOVA of repeated measures, the intra and intersubject effect will be observed. The effect size will be calculated using Cohen's formula. It is expected to see improvement in knee stability and quadriceps strength in athletes who performed the exercise protocol, after the study period.
The aim of this study is to evaluate the speech performance of professional rugby players when using custom-fitted mouthguards over a six-month period. Consented players will be given custom-fitted mouthguards and they will be instructed on the use and care of the mouthguards. At five time points: baseline, immediately following mouthguard use (T1), one-week after- (T2), one-month after- (T3) and six-month after use (T4), participants are required to pronounce four selected phonemes. Three recordings will be made for each phoneme. Spectrspectrographic analysis will be performed to assess the acoustic characteristics of the sound. Concurrently, they will be asked to fill up a questionnaire on self-assessment of oral impairments. Throughout the six-month period, the compliance of wearing mouthguards and the occurrence of dental trauma during training will be monitored on-site by the researcher or if not available, an assigned coach. A 24-hour helpline will be provided as a surveillance tool to monitor problems with mouthguards and dental trauma.
Introduction. Lower limb injuries are characteristic of rugby players. Core exercises aim to improve ankle stability. The ankle bandage in 8 is used in the approach to injuries to provide better stability in the joint. Objectives. To assess the effectiveness of an intervention through motor control and bandage on lower limb stability in rugby players from 18 to 40 years old. Study design. Randomized, single-blind clinical study with a follow-up period. Methodology. Twenty-five rugby players will be recruited to be randomized to the two study groups: experimental (specific exercises for the Core area and ankle bandage) and control (Core motor control). The intervention will last 4 weeks, with 2 weekly sessions of 15min each. The study variables will be: core motor control (measured with plate test, trunk flexion test and modified Biering-Sorensen test) and the stability of the lower limbs (measured with Double Heel Rise and Single Heel Rise test). A descriptive analysis will be carried out calculating the main statistical characteristics. Through an analysis of Shapiro-Wills the normality of the study groups will be calculated, and through an analysis with the parametric tests of t-student and ANOVA of repeated measures, we will evaluate the difference after the evaluations in both groups and the intra-e intersubject, respectively. Expected results. Increased motor control of the core and stability of lower limbs.
