About this trial
Sport-related concussion (SRC) is a significant concern in soccer. This pilot quasi-experimental trial aims to investigate the efficacy and acceptability of an evidence-based neck resistance exercise program in female soccer athletes for SRC prevention. The 8-week intervention includes dynamic and static neck exercises designed to reduce linear and rotational head accelerations, improve neck muscle strength, and minimise SRC risk. The study will evaluate program outcomes through laboratory testing, questionnaires, and user feedback. Findings from this pilot study will inform the design and implementation of a full-scale study, aiming to advance preventive strategies in SRC and address the underrepresentation of female athletes in research.

Trial outcomes
Primary outcomes
1
Linear head acceleration
Linear head accelerations will be assessed during impulsive loads applied to the head in four cervical directions: flexion, extension, lateral flexion, and rotation. The impulsive load will be induced using a custom-made device, and linear accelerations will be measured with a Qualisys motion capture system, reported in units of gravitational force (g-force).
Time frame
Measurements will be taken at baseline and after the 8-week intervention program.2
Rotational head acceleration
Rotational head accelerations will be assessed during impulsive loads applied to the head in four cervical directions: flexion, extension, lateral flexion, and rotation. The impulsive load will be induced using a custom-made device, and rotational accelerations will be measured with a Qualisys motion capture system, reported in radians per second squared (rad/s²).
Time frame
Measurements will be taken at baseline and after the 8-week intervention program.3
Isometric neck strength
Isometric neck strength measured in all four cervical directions (flexion, extension, lateral flexion, and rotation) using a handheld dynamometer and will be reported in Newtons (N).
Time frame
Measurements will be taken at baseline and after the 8-week intervention program.Secondary outcomes
1
Acceptability of an evidence-based neck resistance training program
The questionnaire, which has been developed in accordance with the Theoretical Framework of Acceptability, consists of seven statements that athletes will rate on a 5-point Likert scale (1=strongly disagree; 5=strongly agree), as well as two open-ended questions.
Time frame
The questionnaire will be distributed to athletes and trainers at the end of the 8-weekOther outcomes
1
Neck Muscle Activation Timing
Surface EMG sensors will be positioned on the neck musculature to measure neck activation patterns during head acceleration tests. The sensors will capture the time of muscle onset relative to the onset of force application to the head, measured in milliseconds (ms).
Time frame
Measurements will be taken at baseline and after the 8-week intervention program.2
Neck Muscle Activation Amplitude
Surface EMG sensors will be positioned on the neck musculature to measure neck activation patterns during head acceleration tests. The sensors will capture the amplitude of muscle activation, which will be reported as a percentage of the amplitudes measured during maximal voluntary isometric neck strength.
Time frame
Measurements will be taken at baseline and after the 8-week intervention program.Sponsors and contacts
