Brief 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. 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.

Outcome Measures

Primary Outcomes (1)

• 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.

  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

  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

  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

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Study Arms (2)

Experimental group

EXPERIMENTAL

Each session of the intervention will have a duration of 15 minutes of specific training taking place two sessions a week, during a period of 5 weeks. The exercises will be performed in the first 15 minutes of the training session. The intervention will include specific exercises of elastic-explosive strength and resistance strength

Other: Elastic-explosive and resistance strength

Control group

ACTIVE COMPARATOR

Each session of the intervention will have a duration of 10 minutes of specific training taking place two sessions a week, during a period of 5 weeks. The exercises will be performed in the first 15 minutes of the training session. The intervention will include specific exercises of elastic-explosive strength

Other: Elastic-explosive strength

Interventions

Elastic-explosive and resistance strength OTHER

The resistance exercises are: running (3 minutes), 2 farmers carrying marching, 3 side to side ankle hops, 4 plyo lunge jump, 5 lateral jump over barrier, 2 monopodalic jump with ball pass, 3 board throw with half court sprint, 4 lateral shuffle mirror, and 5 combo finisher 4x4. Plyometric exercises are: ankle rotations, knee extension, squat, hip flexion-extension, knee and ankle, ankle mobilizations, squat with rise, pelvis ante / retroversion, global mobilization, stride

Experimental group

Elastic-explosive strength OTHER

Plyometric exercises are: ankle rotations, knee extension, squat, hip flexion-extension, knee and ankle, ankle mobilizations, squat with rise, pelvis ante / retroversion, global mobilization, stride
