Effects of a Prolonged Run and a Three-Week Running Training Program on Lower Extremity Movement Quality in Novice Runners

The purpose of this study was to assess the effects of 1) a prolonged run and 2) a three-week running training program on peak tibial acceleration (PTA) during running, as well as on Functional Movement Screen (FMS) Deep Squat and Active Straight Leg Raise criterion tests. Ten novice runners (4 men, 6 women, age 27± 7.1 years, mass 70.71± 17.05kg) with 14.7± 13.5 months of training experience completed a thirty-minute run at a self-selected pace (2.48 ± 0.58 m/s), and a three-week training program with an approximate 25% weekly increase in running mileage. PTA and FMS were measured at baseline, after the run, and after the program. No significant differences were found in PTA or FMS scores after the run or after the program. In novice runners, PTA and FMS scores may not be affected by a submaximal prolonged run or a three-week period of increased running volume
