Hamstring Injury
Conditions
Brief summary
Aim of the study is to examine the impact of a history of hamstring injury on athletes by determining and comparing the pre- and post-training levels of sprint performance, agility, dynamic balance, and body awareness in football players with and without a history of hamstring injury.
Detailed description
The aim of this study is to compare sprint performance (10-meter sprint test (10mST) and 30-meter sprint test (30mST)), agility (T-Test of Agility), dynamic balance (Y-Balance Test), and body awareness (Body Awareness Questionnaire) levels in licensed football players with and without a history of hamstring injury, before and after training, in order to reveal the effect of a history of hamstring injury on functional performance and acute fatigue response. Capturing acute changes with pre- and post-training measurements and comparing these between groups with and without a history of injury has the potential to make visible "intra-day/intra-training performance fluctuations" that may be overlooked upon returning to the field. This research study is designed as an observational and cross-sectional evaluation study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sprint Performance (10-meter and 30-meter Sprint Tests) | Before and immediately after training | To evaluate the acceleration and maximum sprint performance of the football players, 10-meter and 30-meter sprint tests will be conducted. The 10-meter sprint test will be used to assess acceleration and explosive power capacity over short distances. Participants will stand in a semi-prone position behind the starting line and will begin a 10-meter run at maximum speed upon receiving the starting command. The time will be recorded in seconds. The 30-meter sprint test will be used to evaluate maximum running speed, sprint performance, and anaerobic capacity. Similarly, participants will begin a 30-meter run at maximum speed upon receiving the starting command. The time will be recorded in seconds. |
| T-Test of Agility | Before and immediately after training | This test will be administered to assess participants' agility, speed of change of direction, coordination, and reaction capacity. The test course is arranged in a 'T' shape using cones, with 10 meters forward from the starting point and 5 meters to the right and left. Participant runs forward from the starting point to the midpoint, then moves sideways to the right and left as quickly but steadily as possible, and finally runs back to the starting point. The test duration is recorded in seconds using a stopwatch. Shorter test times indicate a higher level of agility and neuromuscular control. |
| Y Balance Test | Before and immediately after training | The YBT requires the athlete to balance on one leg whilst simultaneously reaching as far as possible with the other leg in three separate directions: anterior, posterolateral, and posteromedial. Therefore, this test measures the athlete's strength, stability and balance in various directions. The YBT composite score is calculated by summing the three reach directions and normalising the results to the lower limb length. |
| Body Awareness Questionnaire (BAQ) | Before and immediately after training | BAQ is an 18-item self-report scale designed to measure how attentive you are to normal, non-emotional internal bodily processes. It evaluates your sensitivity to everyday bodily cycles (like sleep and hunger), ability to detect subtle changes, and capacity to anticipate physical reactions. Typically takes about 3 to 5 minutes. Items are generally rated on a 1 to 7 scale, with higher total scores indicating greater perceived conKdence and accuracy in monitoring your physical state over time. |
