A study testing Plyometric exercises in people with Athletes, run by Investigación en Hemofilia y Fisioterapia at 1 site in Spain.
Trial summary
Introduction. The high jump is a discipline that use the shortening-stretching cycle. Plyometric exersices emply an eccentric load followed by concentric contraction.

About this study
Official title: Efficiency of Plyometric Work Together With the Use of Ballast Weight in Lower Limbs in the Improvement of Performance in Jumpers From 18 to 40 Years Old. Nonrandomized Pilot Study.
Introduction. The high jump is a discipline that use the shortening-stretching cycle. Plyometric exersices emply an eccentric load followed by concentric contraction. Powerinstep is a tool training by means of weigthed weigth whose objective is improving performance in athletes.
Aim. Evaluate efficacy of plyometric training with Powerinstep® in lower limbs, in the performance improvement in professional height jumpers from 18 to 40 years old.

Study design. Non-randomized clinical trial, single bind, with follow-up period.
Methods. 20 athletes will be recruited, that will be randomized to the two study groups: experimental (they carry out a plyometric training programme with Powerinstep) and control (won't be made a intervention on the subjects included in this group). The intervention consists of 6 week, with 2 session for week of 15 minutes duration each. The dependent variables will be the height of the jump, the time of flight, the reaction speed and the impulse force, measures though a pressure platform (model T-PLATE), employing Countermovement Jump, Abalakov and Drop Jump tests. We will make a descriptive statistical analysis. The Shapiro-Wilk statistical test will be used to calculate normality. Trough t-student test of repeated measures and an ANOVA of repeated measures will be calculated the difference between distinct assessment (preintervention, postintervention and follow-up) and the effect intra and inter subject, respectively.
Expected results. We want to observe the changes in performance improvement in height jumpers.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Plyometric exercisesOther
Also called Plyometric training programme with Powerinstep
Jump Drop Jump, dropping the subject from a height of 30cm and then make a vertical jump.
Long jumps asking the athletes to take momentum and make a leap forward trying to reach the greatest possible distance.
Jump Countermovement jump unilaterally, alternating the lower extremities. Jumps 180º with the athletes maintaining a semi-squat position. Jump Countermovement jump repeatedly starting from an upright position and the upper extremities in both hips.
All the exercises will be done through 8 repetitions per session during the first two weeks, increasing two repetitions every two weeks (until reaching 12 repetitions at the end of the intervention).
For the realization of each one of the exercises, the ballasted weight will be used (Powerinstep® model).

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline jump height after intervenion and at month
The height of the jump will be measured on the Countermovement Jump test. The evaluating physiotherapist will stand in front of the subject, who will start from an upright position with the arms on both hips, and will go to a position of flexion of lower members at 90º. Finally, we will ask the subject for a vertical jump on the pressure platform. The results of this test are measured in centimeters and the higher the score, the greater the vertical jump capacity.
Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit
Secondary outcomes (2)
Change from baseline impulse force after intervention and at month
The impulse force will be measured with the Abalakov test. The evaluator will be placed in front of the evaluated, previously in an upright position, asking him to go to a position of flexion of lower limbs of 90º and then, assisted by the impulse of the arms, perform a jump on the pressure platform. The unit of measurement of the results of this test is the Newton, indicating a higher score indicates a greater impulse of the jump.
Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit
Change from baseline vertical jump after intervention and at month
The vertical jump will be measured with the Drop Jump test. In this test, the physiotherapist will stand in front of the subject, who in an upright position will be dropped from a height of 30 centimeters on the pressure platform, then performing a vertical jump with the help of the arms. The results, in this test, are measured in centimeters, where a higher score indicates a greater vertical jump.
Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit

Questions about this trial
What is this clinical trial studying?
A study testing Plyometric exercises in people with Athletes, run by Investigación en Hemofilia y Fisioterapia 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 3 inclusion and 3 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 27 Jan 2020. 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?
Change from baseline jump height after intervenion and at month (time frame: Screening visit, within the first seven days after treatment and after one month follow-up visit). 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 27 Jan 2020.
