摘　　要：BACKGROUND Evidence regarding the effectiveness of using orthotics in improving comfort,increasing running speed and helping to reduce injury rate during running is limited and mixed.Alongside the increasing popularity of running is the increasing rate of running-related injuries(RRIs).Further research into whether orthotics could be used to help reduce RRIs would be highly beneficial for those affected.Additionally,there is a need to clarify whether orthotics use increases comfort during running and helps improve running speed.AIM To investigate whether running with Aetrex Orthotics improves comfort and performance and reduces injury whilst running.METHODS Runners were recruited on a voluntary basis if they were 18 or older with no serious health conditions,ongoing foot pain or deformity,previous foot surgery in their lifetime or any surgery in the past 6 mo.Participants were randomly assigned to either an intervention group or a control group.All participants were asked to complete runs and provide quantitative data regarding comfort during running,running time and distance,and any RRIs over an 8-wk study period.Participants in the intervention group ran with Aetrex L700 Speed Orthotics,whilst participants in the control group ran without orthotics.Other than the addition of orthotics for participants in the intervention group,all participants were asked to run as they usually would.This report presents preliminary data from the first 47 participants recruited for this study.Running speed was calculated from running distance and time and given in miles per hour.For each outcome variable,the mean for each group,effect size and 95%confidence interval were calculated,and a t-test was performed to determine if between-group differences were statistically significant.RESULTS Data for all three primary outcomes was provided from a total of 254 runs by the 23 participants in the intervention group and a total of 289 runs by the 24 participants in the control group.Participants in the intervention group reported higher
