Aim 1: To strength our prediction model for lower extremity (LE) injury established in 2017, we continued to perform the prospective study to determine specific factors that increase a risk of lower extremity injury with our selected outcome measures (dynamic postural control assessment, heart rate variability parameters, gut microbiota profiles, salivary amylase, spinal reflex excitability, hip strength and diaphragm contractility, lower extremity ) in 2018. Hip internal rotation range of motion predicted risk of recurrent ankle sprain. We also identified potential associations of lower extremity injury with the gut microbiota, diaphragm contractility, and breathing pattern.
Aim 2: To determine the effectiveness of a prevention protocol focused on breathing patterns among collegiate football and rugby athletes. Players on teams participated in an breathing based prevention program. Compared to injury rate in previous five years, breathing exercise prevention program reduced overall lower extremity injuries by 23 % in the football team.
In addition to breathing exercises, football players performed supervised 10-minute session 3 times/week for 8 weeks prior to the competitive season that emphasized balance and hip strengthening presented with 6.9% ankle sprain event rate.

理由
While more than two hundred athletes participated in the prediction study (Aim 1), we could recruited only three teams for Aim 2 and have enough statistical power to determine the effectiveness of the immediate efficacy of a yoga-based prevention program on reducing LE injuries. In 2019, we will continue to recruit more teams to strength our injury prevention model among middle school, high school, and collegiate athletes.

| 今後の研究の推進方策 |
To determine the efficacy of yoga-based prevention on reducing injuries, a randomized trial design will be employed in which teams will be designated with a prevention technique in 2019. After screening the teams and establishing high risk and low risk athletes, athletes will receive a yoga-based prevention program with neuromuscular training or neuromuscular training alone during the pre-season. The prevention programs will consist of 18 sessions implemented over a 6-week period. Previously collected data from a similar cohort that received the same screenings and no preventions in 2017 and 2018 will serve as a control group. The injury rates will be compared between the prevention groups as well as high risk and lower risk athletes. In addition, participants will be given a Heart rate variability (HRV)-guided yoga-based cool-down program. The basic idea of using HRV during the comp
etition season is to provide a yoga-based cool-down program when imbalance of the ANS is observed. Lastly, To strength our prediction model for lower extremity (LE) injury established in 2017 and 2018, we continue to perform the prospective study to identify the ideal combination of our selected screening tools in 2019.
