The purpose of this study was to investigate the straight sprint and counter-movement jump related to running with changes of direction using correlational analysis and multiple regression analysis. One hundred and seventy-five male collegiate soccer players, who belonged to the team between the seasons in 2005 to 2010, participated in this study. Different changes of direction tests were conducted every two years. Sprint test and counter-movement jump test were conducted throughout all seasons. Each running with changes of direction was statistically correlated with all sprint times and counter-movement jump. Through multi-regression analysis, however, each running with changes of direction was significantly correlated with different sprint time or counter-movement jump each other. Therefore, it was considered that straight sprint and counter-movement jump related to running with changes of direction, while individual physical factors determining to different running with changes of direction performance would be exist.
