Postural Stability
Conditions
Keywords
proprioception, countermovement jump, postural balance
Brief summary
All the athletes should perform a warm-up consisting of five minutes of jogging and static stretching (Experimental Group 1) or dynamic stretching (Experimental Group 2). Before the beginning of the study and right after performing the stretching protocol, the investigators evaluated the unipedal postural stability, the acustic reaction time, the joint position sense of the knee and the countermovement jump of the athletes.
Interventions
PROCEDUREStatic Stretching
To analyze the immediate effects of static stretching on performance of sprinters
PROCEDUREDynamic Stretching
To analyze the immediate effects of dynamic stretching on performance of sprinters

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in the unipedal postural balance of athletes | baseline and 15 minutes | Monopodal postural stability (15 seconds as still as possible on a baropodometric platform in left-leg and right-leg monopodal support) |
| Change in counter-movement jump of athletes | baseline and 17 minutes | A maximum vertical jump with counter-movement. |
| Change in Joint Position Sense of the knee of athletes | baseline and 20 minutes | Acuity of repositioining a previous position of the knee joint |
| Change in Acustic Reaction Time of athletes | baseline and 22 minutes | Time spent to rise the dominant leg after an acustic signal |
