<p> We investigated changes in ball speed by forehand stroke with take-back action using dorsal-palmar flexion in table tennis. Participants were eleven children aged 8-14 years. Under the forehand stroke with take-back action using dorsal-palmar flexion (take-back stroke condition) and usual stroke condition, electromyograms of the ulnar flexor muscle (UF) and the radial extensor muscle (RE), and motion picture were recorded. The mean ball speed just after the stroke was significantly larger in the take-back stroke condition than in the usual stroke condition. The difference in start timing of muscle activation between UF and RE, which were agonist and antagonist muscles for the forehand stroke, was significantly different between both stroke conditions. Under the take-back stroke condition, the start timing of RE activation was nearly 50-ms faster than that of UF activation. Furthermore, in both muscles, peak amplitude of electromyogram was larger in the take-back stroke condition than in the usual stroke condition. These results suggest that under the forehand stroke with take-back action using dorsal-palmar flexion, earlier activity of RE relative to UF would relate to the increments of the muscle activity and elastic energy in the agonist, and subsequently the mean ball speed just after the stroke would increase.</p>
