Doi: 10.3389/fspor.2025.1717457 Error in author list Please also check that the initials used in the Author Contributions section or elsewhere in the article are correct.Adding/removing authors, changing author order split into twoAuthor Keiichi Ishikawa, Daiki Yamasaki was omitted as an author in the published article. The correct author list reads: Nadaka Hakariya, Takuya Murakami, Keiichi Ishikawa, Daiki Yamasaki, Naotsugu Kaneko, Kimitaka Nakazawa The Author Contributions Statement has been corrected to read: NH, NK, and KN contributed to the conception and design of the study. NH, TM, KI and DY performed the experiments. NH conducted the data analysis and wrote the first draft of the manuscript. KN supervised the study, and NK provided guidance on manuscript preparation. All authors contributed to manuscript revision and approved the final version of the manuscript. The original version of this article has been updated.The order of authors in the author list of the published paper was erroneously given as: Nadaka Hakariya, Takuya Murakami, Naotsugu Kaneko, Kimitaka Nakazawa The correct author list reads: Nadaka Hakariya, Takuya Murakami, Keiichi Ishikawa, Daiki Yamasaki, Naotsugu Kaneko, Kimitaka Nakazawa The original version of this article has been updated.□□□□□□ = □□ - (□□□□□□ □□ %□□□□□□ □□ ) □□ □□□□□□ □□ □□ × □□□□□□ (□□)].The original version of this article has been updated.Adding/removing text 1. Editing the English.We analyzed raw EMG data based on the toss to follow-through of each serve. EMG data analysis focused on the movement of the tennis serve divided into the following four key events: the ball toss (the moment of the ball leave hand), the takeback phase (from the ball toss to the ball impact), the impact (the moment of impact the), and the follow through phase (from impact to the maximal shoulder adduction)..A correction has been made to the section 2. Methods, 2.4.1 EMG pre-processing, Paragraph Number 1:"We analyzed raw EMG data based on the toss to follow-through of each serve. EMG data analysis focused on the movement of the tennis serve divided into the following four key events: the ball toss (the moment when the ball leaves the hand), the takeback phase (from the ball toss to the ball impact), the impact (the moment of ball impact), and the follow through phase (from impact to the maximal shoulder adduction)." 2. Removing parentheses for formula to correct the link.Equation ( 3 [We found that Syn 3 + 4 in P2 could be approximated by the muscle synergy vector of Syn 2 in P1 (r = 0.813). However, Syn 1 in P1 could not be approximated by any of the synergy combinations in P2, which means that Syn 1 in P1 was specific (Fig. 4A).The sparseness of the muscle synergy vector averaged 0.343 and 0.123 for P1 and P2, respectively, with the weightings of P2 was more uniformly distributed than P1. On the other hand, for fractionation of muscle synergy, Syn 2 in P2 could be reconstructed as combination of Syn 1 + 3 from P1, Syn 3 in P2 to Syn 1 + 2 + 4 from P1, and Syn 4 in P2 to Syn 1 + 3 + 4 from P1 in a fractionation of muscle synergy (Fig. 4B)..A correction has been made to the section 3. Results, 3.4 Merging and Fractionation of muscle synergies, Paragraph Number 1 and 2: "We found that Syn3 + 4 in P2 could be approximated by the muscle synergy vector of Syn2 in P1 (r = 0.813).
