Comparing the Effects of Fatigue derived from the Running on different surfaces on the template of Plantar Pressure Distribution

Running is one of the most popular sport activities and However, nobody knows for sure that treadmill running can replicate over ground running conditions. This is an important area of investigation for training and research, and scientific studies have controversies over this matter. There is a question of whether over ground running differs from running on a treadmill. This study aimed to check the consequences of fatigue because of overground and treadmill running on the plantar pressure distribution pattern.Twelve novice athletes (Mean± SD age=۲۶.۰±۲.۵ y, Mean± SD weight: ۵۲.۰±۳.۰ kg, Mean± SD height: ۱۵۹.۰±۵.۰ cm), without sports injuries over the past year, were selected. The study participants took six series of tests as pretests. The time between the treadmill test and the overground test was ۷ days. Immediately after the fatigue protocol, ۶ correct test series of proper running as post tests were taken. Overground and treadmill running created fatigue within the samples. Peak plantar pressure distribution, Center of Pressure, contact area, and impulse the samples were recorded employing a footscan (Footscan Version ۷ Gait ۲nd generation software) pressure system during running before and after the fatigue protocol and analyzed with repeated measures ANOVA in SPSS v.۱۸.Peak plantar pressure on the second to fifth toe, the fourth and fifth metatarsal bones, and medial a part of the heel significantly increased. The shift within the Center of Pressure of the foot was non-significant altogether stages. The contact area at the second metatarsal and midfoot area shifted only before the fatigue protocol on overground running. Impulse at the second to fifth toe, first to fifth metatarsal, significantly increased within the ground running.The results show that fatigue caused by running on the ground and on the treadmill has different effects on the distribution of plantar pressure in running.
