Effects of a Targeted Prevention Program on Change-of-Direction Biomechanics and Performance in Elite Female Soccer Players

Официальное название

Impact of a Targeted Prevention Program on Biomechanics and Performance During Change-of-Direction Tasks in Elite Female Soccer Players: An Interventional Study

Обзор

Anterior cruciate ligament (ACL) injuries are common in female soccer and frequently occur during change-of-direction (COD) movements without contact. Biomechanical deficits during these movements are considered important risk factors. This study aims to evaluate the effects of a targeted injury-prevention program on biomechanical movement quality and performance during change-of-direction tasks in female soccer players. Participants will perform a 90° cutting task during which biomechanical movement quality will be assessed using the Cutting Movement Assessment Score (CMAS), while performance will be evaluated using cutting time measured with photoelectric timing gates. Participants will also perform the 505 Agility Test to assess additional change-of-direction performance. In addition, subjective perceptions of functional confidence and performance will be collected using Likert-scale questionnaires. The study will assess whether a structured prevention program integrated into regular training can improve biomechanical movement patterns and change-of-direction performance.

Подробное описание

Anterior cruciate ligament (ACL) injuries frequently occur during rapid change-of-direction (COD) movements in soccer, particularly in female players. Biomechanical deficits during these movements have been identified as important modifiable risk factors for non-contact ACL injuries.

The aim of this study is to evaluate the impact of a structured injury-prevention program on biomechanical movement quality and performance during change-of-direction tasks in female soccer players.

Participants will complete biomechanical and performance assessments before and after a training period. Movement quality during a 90° cutting task will be evaluated using the Cutting Movement Assessment Score (CMAS). Performance will be assessed using cutting time measured with photoelectric timing gates. Participants will also perform the 505 Agility Test to evaluate additional change-of-direction performance. Subjective perceptions of functional confidence and performance will be collected using Likert-scale questionnaires.

Participants will be allocated to either an intervention group or a control group. The intervention group will complete a structured injury-prevention program integrated into their regular soccer training sessions. The program will be performed twice per week for six weeks, with sessions lasting approximately 30 minutes. It will include exercises targeting neuromuscular control, strength, balance, trunk stability, plyometric ability, and change-of-direction technique in order to improve movement mechanics during change-of-direction tasks. The control group will continue their usual soccer training without the additional prevention program.

The study will evaluate whether the prevention program improves biomechanical movement patterns and change-of-direction performance.
