Introduction. Faced with the risk of injury relapse, and as athletes train and compete, they generate anxiety that limits their ability to push themselves to the maximum, influencing their performance. Objectives. i) To identify the state and trait anxiety of non-professional athletes with previous hamstring injuries; ii) To evaluate the main prognostic factors of anxiety in these athletes; and iii) To analyze the best predictive model of anxiety in soccer players with previous hamstring injuries. Material and method. Ambispective cross-sectional cohort study. 88 players will be recruited. The primary variable of the study will be anxiety (State-Trait Anxiety Inventory), with the number of recurrences of the study injury being the dependent variable. The secondary variables, estimated as modifying or confounding, will be the main sociodemographic variables (age, type of school/work activity), clinical (number of hamstring injuries, number of relapses of injury in the same location, duration of injury in weeks, date of last injury), sports (weekly training load, seasons competing, regular starting line-up) and anthropometric (weight).
Study Type
OBSERVATIONAL
Enrollment
88
In the present study, no intervention will be carried out, with the recruited subjects only completing the questionnaires set out in the study variables.
Assessment of anxiety
Anxiety will be evaluated using the State-Trait Anxiety Inventory. This scale will be used to measure the perception of anxiety of the patients included in the study. The state and trait of anxiety of each subject is evaluated with a score of 0 to 30 points for each scale, where a higher score indicates a higher anxiety index in the trait or state.
Time frame: Screening visit
Assessment of the main sociodemographic variables
In the evaluation of the main sociodemographic variables, the following will be evaluated: age (in completed months) and type of school/work activity (sedentary/active)
Time frame: Screening visit
Measuring the number of hamstring injuries
For the data analysis, each subject will be asked to indicate, among the clinical variables, the number of hamstring injuries they have had over the last 3 seasons
Time frame: Screening visit
Measurement of weekly training load
For the data analysis, each subject will be asked to indicate, among the sports variables, the weekly training load (in hours) that they usually have during the competition stage of the season.
Time frame: Screening visit
Assessment of the main anthropometric variables
In the assessment of the main anthropometric variables, weight (in kg) will be measured.
Time frame: Screening visit
Measuring the duration of hamstring injuries
For the data analysis, each subject will be asked to indicate, among the clinical variables, the duration (measured in weeks) of the hamstring injuries they have had over the last 3 seasons
Time frame: Screening visit
Measurement of the date of the last hamstring injury
For the data analysis, each subject will be asked to indicate, among the clinical variables, the date of the last injury (measured in weeks) to the hamstring muscles over the last 3 seasons
Time frame: Screening visit
Measurement of the number of seasons that the soccer player has been competing
For the data analysis, each subject will be asked to indicate, among the sports variables, the number of seasons that they have been federated, competing in soccer.
Time frame: Screening visit
Measurement of the footballer's regular starting position in the team
For the data analysis, each subject will be asked to indicate, among the sporting variables, the footballer's regular starting position in the football team, with a dichotomous answer (yes/no).
Time frame: Screening visit
