About this study
Official title: The Influence of Acute Static Stretching on the Ankle Joint-position Sense of Soccer Players: a Randomized Controlled Trial
The aim of this study isto investigate the influence of acute static stretching on the ankle joint position sense of soccer players.
Read the detailed 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Static StretchingOther
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.
| Study group | Role | What they receive |
|---|---|---|
| Control Condition | No intervention | 5-minute rest |
| Static Stretching of 30 seconds Condition | Active comparator | Static stretching of the gastrocnemius and tibialis anterior muscles for 30 seconds Receives: Other: Static Stretching |
| Static Stretching of 90 seconds Condition | Active comparator | Static stretching of the gastrocnemius and tibialis anterior muscles for 90 seconds Receives: Other: Static Stretching |
What is being measured
The primary outcome is the main question the study is designed to answer.
Absolute angular error
The absolute value of the difference between the target range and the achieved range
Measured: 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
Measured: Change from Baseline (Before) to Immediately after interventions or control (After)
Variable angular error
The standard deviation of the 3 repositionings
Measured: Change from Baseline (Before) to Immediately after interventions or control (After)

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06320977, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
