We investigated the differences in peak ground reaction force of the stride and the pivot foot of baseball throwing between the different FMSTM scoring groups. Thirteen collegiate baseball position players were divided into two groups, LS (femur below horizontal) and HS (femur above horizontal) adopting the FMSTM “deep squat” screen. During the throwing test, the players completed five throws with maximal effort towards a target. A speed gun and force plates were utilized to measure ball speed and ground reaction force. There was no significant difference in ball speed between the two groups; however, peak vertical reaction force of stride foot was significantly higher in LS group.
