This clinical trial aims to evaluate the effect of a high-speed, low-amplitude physiotherapy technique at the ankle level, when performed on amateur soccer players.

In this randomized, single-blind, cross-sectional and prospective clinical trial, the effect on ankle mobility and changes in plantar pressure centers obtained after performing a high-velocity, low-amplitude physiotherapy technique in amateur soccers will be assessed.

Two intervention groups are used; in one of them this treatment will be applied in a real way, and in the other one a simulation will be carried out.

Inclusion Criteria:

• Men over 18 years old
• Men that played or have played soccer as an amateur or professional on a regular basis
• No previous musculoskeletal history that would contraindicate HLVA techniques (recent fractures, osteosynthesis material placed in the joint, infections...)

Exclusion Criteria:

• Subjects under 18 years old
• Subjects who have suffered musculoskeletal pathology in the lower limb that contraindicates manipulation or who have a medical diagnosis of chronic ankle instability
• Subjects who suffer neurological or cognitive alterations that prevent the understanding of questionnaires or physical tests; and those who have not signed the informed consent documents

Men that played or have played soccer as an amateur or professional on a regular basis
