Purpose: The purpose of this study was to investigate the effects of 6 weeks of plyometric training and resistance training on shoulder proprioception and neuromuscular control in overhead sports club members. Methods: Twenty overhead sports club members participated in this program (male=14, female=6) who regularly participated in overhead sports activities were randomly assigned to a plyometric training group (n=10) and a resistance training group (n=10). The training program consists of 12 types of plyometric exercises and seven types of resistance exercises and it was conducted with the general overhead sports club activities for 6 weeks. Shoulder proprioception through joint position sense (JPS), threshold to detect passive motion (TTDPM) and neuromuscular control through closed kinetic chain upper extremity stability test (CKCUEST), upper quarter Y-balance test (UQYBT), seated medicine ball throw (SMBT), functional throwing performance index (FTPI) were measured before and after training. Results: JPS external rotation (ER), CKCUEST normalization and CKCUEST power, UQYBT, FTPI were significantly improved in both groups after the 6-week training program. Also, TTDPM internal rotation, TTDPM ER, SMBT were significantly improved only in the plyometric training group. Conclusion The conclusion of this study is that both plyometric training and resistance training were shown to be effective in improving proprioception and neuromuscular control, but only plyometric training showed significant improvements in TTDPM and SMBT. Therefore, both trainings were effective in improving JPS ER, CKCUEST, UQYBT and FTPI, but only plyometric training was effective in improving TTDPM and SMBT.
