STUD LENGTH AND STUD GEOMETRY OF SOCCER BOOTS INFLUENCE RUNNING PERFORMANCE ON THIRD GENERATION ARTIFICIAL TURF

The purpose of this study was to evaluate the influence of different stud lengths and stud geometries of soccer boots on soccer specific running performance. The study involved performance testing by running through two functional traction courses and corresponding subjective testing. Variables of this study were objectively measured running times and perception ratings of running performance. 15 experienced soccer players participated in the study. Players run slower when performing with shorter studs (p<0.01). Here, measured running times were reflected by players ’ perception (p<0.01). For stud geometry, bladed studs were more supportive with regard to objectively measured running performance compared to elliptic studs (p<0.05). In contrast, no differences were found with regard to players ’ perception (p=0.19). In conclusion, longer stud length provides better traction resulting in better performance. Bladed studs provide a functional traction advantage compared to elliptic studs with respect to running performance
