The aim of this study isto investigate the influence of acute static stretching on the ankle joint position sense of soccer players.
This crossover randomized controlled trial will include semi-professional soccer players. All participants will perform 3 conditions: two experimental conditions, of static stretching of the gastrocnemius and tibialis anterior muscles, for 30 seconds or 90 seconds; and a control condition (rest). Ankle joint position sense of the dominant limb will be assessed before and immediately after the conditions for the range of 20º of plantar flexion by active repositioning, and using a video camera. Absolute, relative and variable angular errors will be calculated.

| Static Stretching | Other | The static stretching protocol will include the following muscle groups of the dominant lower limb:
These stretchings will be held in a position where the participants refer discomfort, and will be maintained for 30 seconds or 90 seconds according to the condition. |
| Measure | Description | Time Frame |
|---|---|---|
| Absolute angular error | The absolute value of the difference between the target range and the achieved range | Change from Baseline (Before) to Immediately after interventions or control (After) |
| Relative angular error | The arithmetic difference between the target range and the range achieved | Change from Baseline (Before) to Immediately after interventions or control (After) |
| Variable angular error | The standard deviation of the 3 repositionings | Change from Baseline (Before) to Immediately after interventions or control (After) |
