JRCT ID: jRCT1020230044

Registered date:03/12/2023

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Anterior cruciate ligament injury
• Date of first enrollment: 11/12/2021
• Target sample size: 60
• Study type: Interventional

Intervention(s)

The intervention group will implement an ACL injury prevention program created by the applicant. This preventive training aims to strengthen the muscles around the hip joint, learn correct jumping and landing movements, and balance ability. In addition, provide guidance on correct form.
Preventive training is conducted at least three times a week for six consecutive months.
A physical therapist will provide training guidance on a regular basis (two or three times a month).
On days when physical therapists are unable to visit, team coaches and managers provide training guidance.
Regularly hold lectures on injury mechanisms and the knowledge necessary for prevention.

Outcome(s)

Primary Outcome

ACL injury rate (Athlete-exposures: AEs)
AEs is calculated by multiplying the number of ACL injuries by 1000, taking into account the duration of sports activities, using the denominator as exposure time, which is the number of people multiplied by the number of days of practice/games, and the numerator as the number of ACL injuries. Calculate and compare the intervention group and control group.
The number of participants in practices and games, as well as the number of days they were held, will be compiled from practice diaries for both the control and intervention groups.

Secondary Outcome

Lower limb tightness
Knee joint extension/flexion muscle strength
Hip adduction/abduction muscle strength
Dynamic lower limb balance
Joint angles of lower limbs and trunk during one-leg landing and forward one-leg jump landing
