Effect of Nervous System Mobilization on Athletes' Performance

Study Overview
=================
Brief Summary
-----------------
This study aims to compare the effects of two diferente doses of nervous system mobilization on athletes performance.

Detailed Description
-----------------
It is anticipated that 60 athletes will be randomly allocated to receive either 4x10 (n=30) or 8x10 (n=30) repetitions of neural mobilization . Data on flexibility (knee extension test) and lower limb strength and motor control (hop tests and vertical jump test) will be collected at baseline and after the neural mobilization. Statistical analysis will be performed using a mixed-methods ANOVA.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Single Leg Hop Test | Participants are asked to perform one single unipedal jump and the jump width is measured. | Baseline | 
| Single Leg Hop Test | Participants are asked to perform one single unipedal jump and the jump width is measured. | Up to 1 hour after baseline | 
| Crossover Test | Participants are asked to jump as far as possible on a single leg three consecutive times, without losing balance and landing firmly. The total width of the 3 consecutive jumps is measured. | Baseline |

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 6-meter Time Hop Test | The aim is to jump as fast as possible on a single leg over a distance of 6 meters, without losing balance and landing firmly. The time taken to perform this test is the measure of interest. | Baseline |

| Vertical Jump test | Participants are asked to jump upwards and the height jumped is measured. | Baseline | 
| Vertical Jump test | Participants are asked to jump upwards and the height jumped is measured. | Up to 1 hour after baseline | 
| Knee extension test | Participants are in a prone position, hip at 90º flexion and knee extension is performed. The measure of interest is the knee extension angle. | Baseline |
