*denotes significant pairwise comparison.
TSR = traditional shoe wearing rearfoot strikers, MSA = minimalist shoe wearing anterior foot strikers, Chi = Chi trained runners, MSR = minimalist shoe wearing rearfoot strikers. 4-6)įigure 4-6: Average Vertical Loading Rates. This means that impact with the ground is spread out over a longer period of time, thus helping the runner to eliminate sudden impact to the bones and joints which can commonly lead to stress fractures in the bones of the feet, lower legs and hips. Greater Attenuation of Impact: They experienced a smoother landing without the jarring most commonly attributed to heel striking (shown as the smallest Average Vertical Loading Rate AVLR). TSR = traditional shoe wearing rearfoot strikers, MSA = minimalist shoe wearing anterior foot strikers, Chi = Chi trained runners, MSR = minimalist shoe wearing rearfoot strikers, BW = body weights. Data are multiples of body weight (BW) as a function of % stance phase. 4- 7)įigure 4-7: Vertical Ground Reaction Force urves. Lowering the impact a runner has when their foot strikes the ground directly lowers the impact to the knees, helping to counteract the cause of the most common running injury, “runner’s knee.” (Fig. Lower Impact Forces: They experienced the least amount of impact (shown as the lowest average vertical ground reaction force VGRF). Of the four running styles studied, participants practicing ChiRunning showed the following:
MSA Runners with an anterior (forefoot) strike and wearing minimalist shoesĬHI Runners in this group were proficient in the Chi Running technique with a midfoot (full-foot) landing in both traditional and minimalist shoes MSR Runners with a rearfoot strike and wearing minimalist shoes TSR Runners with a rearfoot strike and wearing traditional running shoes The study, A Comparison of Lower Extremity Joint Work and Initial Loading Rates Among Four Different Running Styles, (Goss, 2012) compared four common types of running styles:
Study Shows ChiRunning Technique Reduces ImpactĪ recent 1-year study at University of North Carolina at Chapel Hill shows that the ChiRunning technique was found to produce less impact and higher efficiency, when compared with three other common styles of running.
