Background. Anterior cruciate ligament (ACL) is one of the most commonly
encountered injury in athletes. Poor landing technique is associated with higher
ACL injury risk. Previous studies have proven that ankle dorsiflexion range of
motion (ADROM) is associated with landing knee flexion and knee valgus, which is
associated with the landing technique, especially encountered in women.
Objectives. The aim of this study is to determine the association between ankle
dorsiflexion range of motion and jump-landing quality.
Methods. Respondents were medical students from a private university in Jakarta.
Forty female athletes from college’s soccer, basketball, volleyball, and badminton
associations were recruited with the purposive sampling technique. Ankle
dorsiflexion range of motion was measured with weight-bearing lunge method.
Jump-landing quality was scored with Landing Error Scoring System (LESS). Data
was analyzed using one-way ANOVA and further analyzed with Post-hoc LSD
analysis.
Results. One-way ANOVA analysis showed p value < 0,05 in association between
ankle dorsiflexion range of motion with jump-landing quality. Post-hoc LSD
analysis showed p value < 0,05 in LESS interclass correlation between excellent –
moderate class, excellent – poor class, and good – poor class.
Conclusions. There is a strong association between ankle dorsiflexion range of
motion and jump-landing quality. Ankle dorsiflexion range of motion is direcly
proportional to jump-landing quality. |
