Design outcomes

Primary

MeasureTime frame
Athletes have muscular strength of knee extension of dominant and non-dominant assessed by dynamometry, from a range of at least 10% in the pre-intervention ( 24 hours prior to intervention) and post intervention (24 hours after completion of the intervention). Athletes have jump height measured by the maximum range of the test from a variation of at least 10% in preintervention ( 24 hours prior to intervention) and post intervention (24 hours after completion of the intervention).

Secondary

MeasureTime frame
Athletes have the perception of the global effect of the jump evaluated through a subjective perception scale as it classifies tried his heels in these days, and can respond on a scale al -5 to +5 variation or very much worse better, from a variation of at least 10% in the pre-intervention ( 24 hours prior to intervention) and post intervention (24 hours after completion of the intervention). Athletes have evaluated the amount of jumps through the maximum number of hops test within two minutes from a range of at least 10% in the pre-intervention ( 24 hours prior to intervention) and post intervention (24 hours after completion of the intervention).
