Summary

The overall purpose of this study is to quantify the effect and retention of one-week training of falling techniques on landing biomechanics associated with anterior cruciate ligament (ACL) loading compared to soft-landing techniques in young recreational athletes. The secondary purpose is to assess the safety of the training program.

Aim 1: To quantify the effect of one-week training of falling techniques on landing biomechanics during forward, lateral, vertical, and diagonal landings compared to soft-landing techniques. We hypothesize that falling techniques will result in increased knee flexion angles and decreased landing forces, knee abduction and internal rotation angles, and knee moments for all landing directions compared to soft-landing techniques immediately after the training.

Aim 2: To assess the retention effects of the falling techniques on landing biomechanics compared to soft landings. We hypothesize that the effects of falling techniques on ACL loading variables will be more highly retained compared to soft-landing techniques two weeks after the training.

Aim 3: To identify the safety of the training program. We hypothesize that participants can complete the training without suffering minor, moderate, or major injuries, while occasional minor bruises might be observed.

Falling Training

For the falling training, participants will be instructed to initially land softly with increased knee and hip flexion and then smoothly fall to the direction of the movement while transferring the weight from the feet to the hands and subsequently to the lateral trunk and hip. The training program includes three one-hour training sessions over a week with one or two days between two sessions. Each training session will begin with a warm-up protocol. Participants will progressively increase the task difficulty and decrease the thickness of the mat. For each training session, participants will perform a minimum of one successful practice trial for each task difficulty and each landing direction on the thicker mat and then complete a minimum of three successful practice trials for each task difficulty and landing direction on the thinner mat. The last training session involves falling on a 0.5-inch mat, which is the same as the surface for the post-training and retention assessments.
