Brief Summary

This study aims to find out whether an 8-week sports injury prevention program can improve lower-body performance-such as power, agility, and balance-among female college athletes in Saudi Arabia. Sports participation has increased among women in Saudi Arabia, but many injury-prevention programs were originally designed for male athletes and may not meet the specific needs of females. This study will help determine whether a tailored program can reduce injury risks and improve athletic performance. Female athletes aged 18-35 years who have been training and competing for at least one year can participate. Athletes with recent injuries, pregnancy, or chronic medical conditions that could affect performance will not be included. Participants will complete tests before and after the program, including jumping, balance, and agility assessments. The prevention program includes warm-up exercises, stretching, strengthening, jumping drills, balance work, and agility training. By comparing results before and after the program, the study will show whether this type of training can help female athletes stay safer and perform better.

Outcome Measures

Primary Outcomes (3)

• Change in Lower-Extremity Functional Performance

  Description: Assessed using the Lower Extremity Functional Test (LEFT), which evaluates multidirectional agility through eight standardized tasks (forward run, backward run, side shuffle, carioca, figure-8 run, 45° cuts, 90° cuts, and countermovement jump). Time Frame: Baseline and 8 weeks (post-intervention). Outcome Metric: Total completion time (seconds). Lower times indicate better performance.

  From enrollment to the end of treatment at 8 weeks

• Change in Lower-Body Explosive Power

  Description: Measured using the Countermovement Jump (CMJ) and Standing Long Jump (SLJ) tests, both widely validated for assessing lower-limb power. Time Frame: Baseline and 8 weeks. Outcome Metric: CMJ height (cm) and SLJ distance (cm).

  From enrollment to the end of treatment at 8 weeks

• Change in Dynamic Balance

  Description: Evaluated using the Star Excursion Balance Test (SEBT) in the anterior, posteromedial, and posterolateral directions. Outcome Metric: Max reach distance (cm), normalized to leg length.

  From enrollment to the end of treatment at 8 weeks

Exercise group

EXPERIMENTAL

Participants will attend supervised injury-prevention sessions for eight weeks. Each session includes: Warm-up drills (jogging, shuttle runs, backward running) Stretching for major lower-body muscles Strength training such as lunges and hamstring exercises Plyometric drills (jumping and bounding) Balance exercises on one leg Agility drills such as directional running Cool-down stretching and core exercises This type of program is commonly used to reduce lower-limb injuries by improving strength, stability, coordination, and movement control.

Behavioral: 8-Week Sports Injury Prevention Program

Interventions

8-Week Sports Injury Prevention Program BEHAVIORAL

A structured 8-week injury prevention exercise program designed to improve lower-extremity strength, balance, agility, and movement control in female college athletes. Each supervised session includes: Warm-up: jogging, shuttle runs, backward running Stretching: calf, quadriceps, and hamstring stretches Strengthening: walking lunges, Russian hamstring exercise, single-leg toe raises Plyometrics: lateral, forward, and backward jumps; zigzag shuffle; bounding drills Balance training: single-leg stance with chest pass, forward bend, and figure-of-eight reach Agility drills: multidirectional shuttle runs, diagonal runs, bounding runs Cool-down: bridging, abdominal crunches, knee-to-chest stretches, and seated butterfly stretch Sessions follow a standardized protocol with prescribed repetitions, sets, or time durations for each component. The goal of the intervention is to enhance athletic performance and reduce the risk of lower-extremity sports injuries.
