Summary

BACKGROUNDː The reverse nordic hamstring exercise is developed for the eccentric work of the rectus femoris. After performing Nordic exercise protocol (its original), the relationship between increased eccentric hamstring strength, improvements in sprint capacity and reduced incidence of injuries can be confirmed. The review of evidence, led us propose the relationship and the possible benefits that could exist in the performance of four weeks of reverse nordic exercise protocol and the vertical jump, measured with countermovement jump test (CMJ) on a platform of jump.

METHODSː An open randomized controlled trial was conducted, with an intervention and control group, to which they were randomly assigned. The sample was made of 19 players from the San Antonio de Murcia Catholic University Team in the youth A category, aged between 16 and 18 years old. The experimental group (n=10) performed the reverse nordic hamstring exercise protocol for four weeks, in addition to the usual training that they shared with the control group (n=9). Data collection for the CMJ test was done before starting the protocol and immediately after finishing it for all participants. Statistical analysis was carried out with the SPSS program.

PROCEDURE

Nordic Reverse Protocol

The participant begins on their knees, with the trunk upright and fully aligned. At this moment, the soccer player slowly leans back, maintaining the starting position by means of a controlled flexion of the knees. This fall is executed at the lowest speed possible to maximize muscle load in the eccentric phase and reach the point of maximum flexion.
