This study aimed to examine upper body muscle engagement during the forehand smash in table tennis using two different racket coverings—inverted and short-pimpled. Seven male university-level table tennis players (mean age 20.12 ± 2.38, height 164.9 ± 7.5 cm, weight 67.5 ± 5.2 kg) with adequate playing experience participated. Approval was obtained from the research committee, and participants were ensured to be physically fit. Electromyographical signals were recorded from four upper body muscles (Biceps Brachii, Triceps Brachii, Trapezius, and Anterior Deltoid). Root Mean Square (RMS), an EMG signal variable, was analyzed for maximum muscle involvement. Paired t-test method compared muscle activation with both racket coverings, using mean and standard deviation for descriptive statistics. While none of the muscles exhibited a significant difference in activation levels, Biceps Brachii and Trapezius showed higher RMS values with the Inverted covering, whereas Triceps Brachii and Anterior Deltoid had higher RMS values with the short-pip covering. Despite the forehand smash's offensive significance, its accuracy control remains challenging, particularly within a designated target area, as highlighted in previous studies citing the superior spin production of inverted rubber over pimpled rubber.
