Effect of Nervous System Mobilization on Athletes' Performance

This study aims to compare the effects of two diferente doses of nervous system mobilization on athletes performance.

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Other: neural mobilization

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Low dose neural mobilization; Four series of 10 repetitions of neural mobilization targeting the tibial nerve.	Other: neural mobilization; This is a type of mobilization that uses a specific combination of joint movements
Active Comparator: High dose neural mobilization; Eight series of 10 repetitions of neural mobilization targeting the tibial nerve.	Other: neural mobilization; This is a type of mobilization that uses a specific combination of joint movements

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
