About this study

Official title: Effects of a Strength Training Program in Inertial Machines on Squat Jump, Countermovement Jump and Abalakov in Youth Volleyball Players

Objective: To determine the effect of strength training in inertial machines, on SJ CMJ and CMJ with arms; in youth volleyball players from the city of Cartago.

Methodology: A quasi-experimental study of quantitative order was carried out and takes up an empirical-analytical approach, quasi-experimental with pre-test - post-test evaluation. 32 female volleyball players, belonging to the minor category of the Fénix G Club of the city of Cartago Valle

Results: Both groups showed significant improvements in jump height, flight time, strength and power in the protocol that was carried out during the 12 weeks of intervention, but there was no statistically significant difference between the control groups (P = 0.356). , experimental (P = 0.984)

Conclusions:

Objective: To determine the effect of strength training in inertial machines, on SJ CMJ and CMJ with arms; in youth volleyball players from the city of Cartago.

Methodology: A quasi-experimental study of quantitative order was carried out and takes up an empirical-analytical approach, quasi-experimental with pre-test - post-test evaluation. 32 female volleyball players, belonging to the minor category of the Fénix G Club of the city of Cartago Valle. The techniques that were used were: survey to determine previous injuries, adaptations that athletes may have against strength training and practice time in volleyball, observations were also developed to determine the levels of jumpability of each player, taking into account the Bosco's battery (3). For this we used:

  • My jumps 2 application for IOS devices, it was used to determine the height of the CMJ, SJ, CMJ or ABK, this app was validated in 2015 by the creator, Dr. Carlos Balsalobre (15).
  • Wheeler YOYO XS inertial machine contains an encoder validated by the company Chronjump (16) with this device the training program was carried out with the volleyball players, the program was subjected to expert judgment.

For the collection of information on sociodemographic variables, a data record was carried out (Weight, Height, History of injuries, etc.), in addition to this, a record per athlete for the values of each jump performed.

Results: Both groups showed significant improvements in jump height, flight time, strength and power in the protocol that was carried out during the 12 weeks of intervention, but there was no statistically significant difference between the control groups (P = 0.356). , experimental (P = 0.984)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Inertial Strength trainingDevice

    Also called Conventional strength training

    Low speed strength training with classic movements, derived from Olympic lifting and jumping

Group 1ExperimentalStrength training in inertial machines for 2 days and around 12 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Independent variable: Inertial machine program

    Power (watt)

    Measured: 12 weeks of intervention

  2. Dependent variable: countermovement jump, squat jump and abalakov.

    Squat position with arms at the waist looking for a countermovement and height, the following jump squat position hold for 5 seconds and look for height without taking the hands off the waist, finally the abalakov is a jump with loose arms performing a countermovement and looking height.

    Measured: 12 weeks of intervention

Secondary outcomes (1)

  1. To compare the differences pre and post strength training in inertial versus conventional machines, pre-post control experiment on the SJ, CMJ and ABK in youth volleyball players.

    Squat position with arms at the waist looking for a countermovement and height, the following jump squat position hold for 5 seconds and look for height without taking the hands off the waist, finally the abalakov is a jump with loose arms performing a countermovement and looking height.

    Measured: 12 weeks of intervention

Where is the study taking place?

The record lists 1 site in Colombia. 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?

Independent variable: Inertial machine program (time frame: 12 weeks of intervention). The study lists 2 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 NCT06159036, which also lists 4 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?
