Eight elite female players participated and were instructed to hit the ball down the line and cross-court using a topspin backhand. Kinematic and kinetic data were collected. The results show that at the impact, participants had a greater wrist flexion angle in DL than CC (p = 0.017). The angular velocity of shoulder flexion (p = 0.038), shoulder abduction (p = 0.006) and thorax\u2013pelvis internal rotation (p = 0.017) was faster when participants impacted the ball DL than CC. As for the joint kinetics, the shoulder external rotation moment was greater in CC than DL (p = 0.043). For a high-quality DL technique, it is important to exhibit a greater wrist flexion and have faster adduction and flexion in the shoulder, as well as faster internal rotation in thorax\u2013pelvis, while having a smaller wrist flexion and more external rotation power in the shoulder are important to perform a CC at the impact. If these key and different factors of hitting CC and DL are ignored, it may lead to failure to complete a high-quality shot.<\/jats:p>","DOI":"10.3390\/ijerph19095146","type":"journal-article","created":{"date-parts":[[2022,4,23]],"date-time":"2022-04-23T08:14:06Z","timestamp":1650701646000},"page":"5146","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Biomechanical Comparison between Down-the-Line and Cross-Court Topspin Backhand in Competitive Table Tennis"],"prefix":"10.3390","volume":"19","author":[{"given":"Kaige","family":"Xing","sequence":"first","affiliation":[{"name":"Department of Physical Education, Chang\u2019an University, Xi\u2019an 710064, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lanping","family":"Hang","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Chang\u2019an University, Xi\u2019an 710064, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zijun","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Exercise Science, School of Physical Education, Shaanxi Normal University, Xi\u2019an 710119, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuangui","family":"Mao","sequence":"additional","affiliation":[{"name":"Department of Exercise Science, School of Physical Education, Shaanxi Normal University, Xi\u2019an 710119, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Chang\u2019an University, Xi\u2019an 710064, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Kinesiology and Physical Education, Faculty of Education, McGill University, Montreal, QC H2W 1S4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9071-7379","authenticated-orcid":false,"given":"Yuliang","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Exercise Science, School of Physical Education, Shaanxi Normal University, Xi\u2019an 710119, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,23]]},"reference":[{"key":"ref_1","first-page":"195","article-title":"How to coach world-class athletes of table tennis","volume":"6","author":"Wu","year":"2010","journal-title":"Int.
