Abstract :In our study that we aimed to see the differences between footballers’ plantar pressure distribution and sedentary individuals’ in total 31 males [(FG)n=19; age=20.66±1.31 years; body length=178.7±4.64 cm; body weight=75,3±6.1kg), 12 sedentary volunteers (n=12; age= 21.05±2.3 years; body length=177.5±4.8cm; body weight=73.55±8.69 kg)] participated. Right, and left foot dynamic plantar pressures were obtained at 100Hz sample speed with the method of 5 steps dynamic walking. The foot was separated into masks by being divided into 14 different pieces. "MH1: 1. Metatarsal head, MH2: 2. Metatarsal head, MH3: 3. Metatarsal head, MH4: 4. Metatarsal head, MH5: 5. metatarsal head, big toe, 2nd toe, 3rd 4th 5th toes, forefoot, mid foot, hind foot and total foot”. Peak pressure (PP – kPa), maximal force (MFN), contact area (CA - cm2), contact time (CT– ms) Maximal force normalized to body weight (MFNBW) values were calculated for total foot. Whether there are significant differences between the groups were tested with independent sample t-tests by using SPSS 20.0 software. It is seen that statistically significant differences between football and sedentary groups are in the parameters of MH1 left foot peak pressure (FG:177,8947±76,87; SG:270,9091±161,83), MH4 mean pressure right foot (FG:113,1444±27,75; SG:88,8058±37,41), MH5 max force right foot (FG:42,3667±10,33; SG:29,9917±12,94) and MH5 mean pressure right foot (FG: 66,5156±18,85; SG:46,94±19,36). It might be reached as a result that the main reason of differences in plantar pressure distribution emerged between FG and SG groups is the intense workout and these pieces’ being used much.
