Clinical Trial Summary

The aim of this study isto investigate the influence of acute static stretching on the ankle joint position sense of soccer players.

Description:

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.

• without history of lower limb injuries in the last 6 months

Exclusion Criteria:

• those with cardiorespiratory, vestibular or neurological diseases

Intervention

Other:
• Static Stretching
The static stretching protocol will include the following muscle groups of the dominant lower limb: Gastrocnemius - Participants will assume a bipedal position facing a wall. Then, the leg that is not being stretched will be placed forward, with the knee in semi-flexion, and the leg that is being stretched, behind, with the knee in full extension. Instructions will be given in order to keep the calcaneus on the floor; Tibialis anterior - Participants will be facing a wall, with the entire foot in touch with the ground and toes pointing forward. Then, they will secure themselves to a handrail and project the hips back. 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.

Primary	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)
Primary	Variable angular error	The standard deviation of the 3 repositionings	Change from Baseline (Before) to Immediately after interventions or control (After)
