Abstract: Objective To compare the differences in biomechanical characteristics between maximal-force-oriented and placement-accuracy-oriented movement executions of table tennis forehand loop drive, and to provide a theoretical basis for athletes to improve placement accuracy. Methods A motion capture system, a force platform, and a surface electromyography (sEMG) system were used to collect biomechanical data of maximal-force and placement-accuracy executions from 24 national first-grade and second-grade athletes. A paired-sample t-test was employed for statistical analysis. Results 1) The racket velocity at impact in placement-accuracy executions was approximately 87%-92% of the maximum racket velocity (P<0.01); 2) The peak time of trunk left lateral tilt angular velocity was significantly delayed by approximately 4.3% (P=0.02) and trunk left axial rotation was delayed by approximately 4.4% (P=0.03) relative to the swing initiation time in placement-accuracy executions， while no such significant difference was observed in maximal-force executions (P>0.05); 3) The peak time of wrist flexion angular velocity was significantly delayed by approximately 3.8% (P=0.02) and wrist adduction was delayed by approximately 7.1% (P<0.01) relative to the ball contact moment in maximal-force executions, while no such significant difference was observed in placement-accuracy executions (P>0.05); 4) Compared with the maximal-force executions, the contribution rate of elbow muscle groups in the placement-accuracy executions increased by approximately 5% (P<0.01), and the activation onset time of the brachioradialis was advanced by approximately 17% (P<0.01). Conclusion To improve the placement accuracy of forehand loops in table tennis, it is appropriate to strike the ball at approximately 87%-92% of the individual maximum racket velocity, promote earlier force generation in distal joints, weaken the whipping movement pattern.
