Background: The anterior cruciate ligament (ACL) is one of the most common injuries in sports activities. Current ACL injury prevention programs have shown suboptimal long-term results. Recent literature show beneficial results of adopting an external focus of attention in several motor activities. Optimizing current ACL injury prevention programs with an external focus of attention might therefore be promising. Objective: The purpose of the present study was to obtain information on the possible impact of internal- and external focus and a video instructed group in the drop jump landing strategies. Methods: Subjects (n=40) were randomly assigned to one of the four groups; internal focus group (IF) (n=10), external focus group (EF) (n=10), video group (VI) (n=10) or the control group with no specific instruction (CTRL) (n=10). Subjects performed the LESS test in five conditions: a pretest (baseline measurements), two training blocks, a posttest directly after the training sessions and a retention test one week later. Group specific instructions were offered in both training blocks only. Results: The VI group showed a significant lower total LESS score indicating an improvement in landing technique as assessed with the LESS of the lower extremity in training block 2 (p=0.007), posttest (p=0.033) and retention test (p=0.048) compared to the internal focus group with verbal instructions. Within the VI group, significant differences in total LESS score were found between pretest and TR1 (p=0.022) and between TR1 and TR2 (p=0.005). Furthermore the EF group scored significantly lower in total LESS score in training block 1 compared to the pretest (p=0.044). Conclusion: Coaches and medical staff are encouraged to use an external focus of attention. It is suggested that an external focus of attention could reduce the risk of an ACL injury.
