About

This clinical trial investigates the effectiveness of manual lymphatic drainage (MLD) in accelerating recovery following induced fatigue in female football players. The study integrates objective performance measurements using linear encoders with anthropometric assessments and psychophysiological evaluations. It aims to quantify the impact of MLD on neuromuscular recovery, muscle edema, and perceived fatigue, considering sex-specific physiological factors and the influence of sleep and psychological stress. The findings will contribute to developing non-invasive, individualized recovery strategies to enhance performance and reduce injury risk in women's football.

Full description

This study aims to assess the effectiveness of manual lymphatic drainage (MLD) as a recovery strategy following induced fatigue in female football players. The intervention is applied immediately after a standardized fatigue protocol using a linear encoder to objectively measure performance decline. The study adopts a multidimensional approach, integrating biomechanical, physiological, and psychometric variables to evaluate recovery.

Participants will undergo three experimental sessions involving a fatigue protocol followed by either MLD or control conditions. Performance will be assessed through guided machine squats, measuring the number of repetitions and time until a 20% velocity loss. Thigh circumference will be measured pre- and post-intervention to monitor fluid shifts and potential edema. Subjective recovery perception will be recorded, and emotional state will be evaluated using the Hospital Anxiety and Depression Scale (HADS). Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI) to explore its influence on fatigue and recovery response.

This trial addresses the need for non-invasive, efficient recovery strategies tailored to female athletes, considering sex-specific physiological and psychological factors. The findings may contribute to optimizing post-exercise recovery protocols and reducing injury risk in women's football.

Description:

The study consists of three visits. During the first visit, participants are informed about the study, eligibility criteria are verified, informed consent is obtained, and baseline assessments are conducted using psychophysiological questionnaires and thigh circumference measurements. In the second visit, assessments are repeated and fatigue is induced through guided squats at 50-60% of estimated 1RM, monitored via a linear encoder. Fatigue is defined as a 20% loss in execution velocity. Immediately after fatigue induction, manual lymphatic drainage (MLD) is applied for 10 minutes (5 minutes per quadriceps), following Emil Vodder's standardized technique. Post-intervention, performance testing and measurements are repeated. The third visit, conducted 15 days later, serves as a follow-up to evaluate sustained effects without further intervention, repeating the fatigue protocol and all assessments.
