About this study
Official title: Effects of a Multimodal Exercise Program on the Kinematics and Sprint Performance of Young Rugby Players: an Experimental Study.
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Sprint performance
Sprint performance measured with MySprint. Resulting from maximal 30-m sprint, six pairs of brands with parallax corrected will be placed at 0, 5, 10, 15, 20 and 30 m to measure the five different split times in seconds during the 30-m trials. The camera, which records 240 frame per second, will be situated on a tripod (in the sagittal plane) 10 meters away from the fourth marker in meter 15.
Measured: Change from baseline and between group differences in sprint performance after the intervention period of 6 weeks
Force-Velocity Profile (F-V)
F-V Profile measured by My Sprint App, resulting from maximal 30-m sprint, theorical maximal horizontal force (F0), maximal mechanical power output in the horizontal direction (Pmax), rate of decrease in RF with increasing speed during sprint acceleration (DRF), Slope of the linear F-V relationship (Sfv), Ratio of force (RF) and maximal value of RF (RFmax). The camera, which records 240 frame per second, will be situated on a tripod (in the sagittal plane) 10 meters away from the fourth marker in meter 15.
Measured: Change from baseline and between group differences in horizontal force-velocity profile after the intervention period of 6 weeks
Sprint spatiotemporal and kinematics
Sprint spatiotemporal and kinematics will be analyzed with Kinovea program (v.0.8.15). The following variables will be analyzed: contact time (s), length step (m; horizontal displacement between the toe tips at adjacent touchdowns), step rate (Hz; the reciprocal of step duration). Moreover, in the frame that the foot touchdown and the frame that the foot touch off trunk and hip (ipsilateral and contralateral) angles will be quantified. The camera, which records 240 frame per second, will be situated 9 meters away from 22.5 m on a tripod at a height of 1.1 meters in the sagittal plane.
Measured: Change from baseline and between groups in sprint spatiotemporal and kinematics at 6 weeks

Questions about this trial
What is this clinical trial studying?
A study testing Multimodal exercise program in people with Exercise Training and Rugby, run by University of the Balearic Islands at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Oct 2024. 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?
Sprint performance (time frame: Change from baseline and between group differences in sprint performance after the intervention period of 6 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05485506, which also lists 8 linked publications.
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 21 Oct 2024.
