Abstract


The purpose of this prospective study was to examine the longitudinal changes in shoulder ER ROM and relative IR strength in elite youth baseball pitchers over one year and to determine their associations with changes in ball speed for throwing fastballs. One hundred and five Dutch elite youth baseball pitchers were measured three times over a period of one year. Statistical analyses of the data revealed that changes in ER ROM and relative IR strength were not significantly associated with changes in ball-throwing speed.
