This study compared the muscle activation patterns of professional and amateur male badminton players during this movement. A total of 24 players (12 professionals and 12 amateurs) participated, with surface electromyography (sEMG) used to measure the activity of 12 muscles on the right side during the lunge. The movement was divided into swing and support phases based on ground reaction force data. The sEMG signals were analyzed using integral EMG (iEMG) and root-mean-square (RMS) amplitude, and muscle synergy patterns were extracted via non-negative matrix factorization (NNMF) and k-means clustering. The results showed significantly higher iEMG and RMS values in muscles such as the gastrocnemius, biceps femoris, gluteus maximus, external oblique, and latissimus dorsi in professional players (p &lt; 0.05), while no significant differences were observed in the tibialis anterior, vastus medialis, vastus lateralis, deltoideus, biceps, and soleus muscles. Muscle synergy analysis revealed three activation patterns in the professional group, compared to two in the amateur group. The additional synergy pattern in the professional players involved greater recruitment of lower limb and core muscles, especially during the support phase. In contrast, the amateur group showed earlier muscle activation but exhibited less efficient coordination. These findings suggest that muscle activation and coordination patterns in the forward lunge are influenced by playing level, highlighting the importance of lower limb and core training for badminton athletes to optimize performance and reduce injury risk.<\/jats:p>","DOI":"10.3390\/s25061644","type":"journal-article","created":{"date-parts":[[2025,3,7]],"date-time":"2025-03-07T04:29:59Z","timestamp":1741321799000},"page":"1644","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Characterization of Muscle Activation and Muscle Synergism in the \u2018Forward Lunge\u2019 Gait Movement of Badminton Players Using Surface Electromyography Sensors"],"prefix":"10.3390","volume":"25","author":[{"given":"Jian","family":"Jiang","sequence":"first","affiliation":[{"name":"School of Athletic Performance, Shanghai University of Sport, Shanghai 200438, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haojie","family":"Li","sequence":"additional","affiliation":[{"name":"School of Athletic Performance, Shanghai University of Sport, Shanghai 200438, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Xiu","sequence":"additional","affiliation":[{"name":"School of Athletic Performance, Shanghai University of Sport, Shanghai 200438, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"458","DOI":"10.1002\/tsm2.220","article-title":"Analgesic drug use of recreational and competitive badminton players: Starting points for prevention","volume":"4","author":"Ochsmann","year":"2021","journal-title":"Transl.
