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.

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