Elastic-explosive Strength Training Combined With Active Joint Mobilizations in Basketball Players
A study testing Elastic-explosive and resistance strength and Elastic-explosive strength in people with Basketball Players, run by Investigación en Hemofilia y Fisioterapia at 1 site in Spain.
Trial summary
The specific training of the elastic-explosive force of the muscles involved in vertical jump and active mobilizations is used to improve the quality of the jump.

About this study
Official title: Efficacy of a Physiotherapy Intervention Through an Elastic-explosive Strength Training Combined With Active Joint Mobilizations, on the Improvement of the Efficiency of Repeated Vertical Jumping in Basketball Players
The specific training of the elastic-explosive force of the muscles involved in vertical jump and active mobilizations is used to improve the quality of the jump. It is also intended to reduce the loss of centimeters, recovery times and fatigue produced during a series of vertical jumps.
The objective of the study is to assess the effectiveness of active mobilizations together with specific training in lower limbs, in ankle mobility, the perception of effort and the height and resistance of vertical jumping in amateur basketball players.

Randomized clinical study. 50 basketball players from 20 to 35 years will be randomized to the study groups: control group (resistance strength exercises, elastic-explosive force) and experimental group (resistance strength exercises, elastic-explosive force together with active mobilizations). The dependent variables will be: repeated jump (15 second Jump test, my Jump 2), maximum vertical jump (CMJ free arms, my Jump 2), subjective perception of effort (Borg scale) and ankle dorsiflexion (goniometer). The sample distribution will be calculated using a Kolmogorov-Smmirnof analysis. 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 observe an improvement in the resistance of vertical jumps, with a decrease in the loss of centimeters in the repetitions of jumps.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline maximum vertical jump after treatment and at month
The My Jump 2 application will be used. With the video we can see the moment when the feet do not touch the ground and with this data the application automatically calculates the height in centimeters. From a squat position, the player will have to perform a vertical jump, landing in the same starting position.
Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit
Secondary outcomes (3)
Change from baseline resistance of the explosive force after treatment and at month
The 15 sec repeated jump test will assess the resistance of the explosive force. With the My Jump 2 application we will calculate the height in repeated jumps in 15 seconds. To do this, we will ask the athlete to, from a squat position, perform 15 repeated vertical jumps, returning to the starting position every time.
Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit
Change from baseline subjective perception of effort after treatment and at month
We will use the modified Borg scale with a scoring range of 1 to 10 points (the higher the score, the greater the perception of effort). The concept of perceived effort is a subjective assessment that indicates the person's opinion regarding the intensity of the work performed. 1 indicates little fatigue, 10 is the maximum effort perceived by the athlete
Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit
Change from baseline dorsal ankle flexion after treatment and at month
This variable will be measured with the use of a goniometer. With the athlete standing, from a stride position, with the first finger placed 10 cm from the wall, we will ask him to do a knee flexion towards the wall, with the heel always resting on the floor. We will place the goniometer axis in the center of the outer malleolus. The fixed arm will be parallel to the ground, while the mobile arm will be aligning the fibula. The unit of measure is the degrees.
Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit
