Countermovement jump\u00a0(CMJ), sprint time (5, 10, and 15\u00a0m), change-of-direction (COD) performance (right and left), medicine-ball throws (overhead, forehand, and backhand), and serve velocity were included as tests at baseline, week 4, and week 8. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> Both MG and FG largely improved from baseline to weeks 4 and 8 of training in CMJ (11.6, 10.6%; effect size [ES]\u2009=\u20091.24, 1.95). Also, sprint time 5\u00a0m and 10\u00a0m, COD performance-right, and COD performance-left improved moderately to very largely at week 4 in MG (\u22125.0% to \u22126.2%; ES\u2009=\u2009\u22121.79 to \u22124.19) and FG (\u22122.9% to \u22125.1%; ES\u2009=\u2009\u22121.13 to \u22121.64), respectively. Regarding medicine-ball throw, only FG improved moderately to very largely from weeks 4 to 8 in overhead (9.3%; ES\u2009=\u20091.46), forehand (8.0%; ES\u2009=\u20091.08), and backhand (6.1%; ES\u2009=\u20091.15). Serve velocity improved moderately from weeks 4 to 8 in MG (5.8%; ES\u2009=\u20090.87). <jats:italic><jats:bold>Conclusions<\/jats:bold>:<\/jats:italic> Four weeks of the tested programs seem sufficient to improve physical determinants in young female participants. Greater improvements in CMJ and medicine-ball throw following flywheel neuromuscular training indicate the importance of including exercises that emphasize the stretch-shortening cycle and involve the entire kinetic chain. Performing the same intervention with no load adjustments may stall or even decrease performance in some parameters from weeks 4 to 8.<\/jats:p>","DOI":"10.1123\/ijspp.2022-0082","type":"journal-article","created":{"date-parts":[[2022,12,21]],"date-time":"2022-12-21T09:09:25Z","timestamp":1671613765000},"page":"123-134","source":"Crossref","is-referenced-by-count":11,"title":["Performance Outcomes Following Isoinertial or Machine-Based Training Interventions in Female Junior Tennis Players"],"prefix":"10.1123","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2778-3960","authenticated-orcid":true,"given":"Jose","family":"Can\u00f3s","sequence":"first","affiliation":[{"name":"National Institute of Physical Education of Catalonia (INEFC), University of Barcelona, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2630-6684","authenticated-orcid":true,"given":"Francisco","family":"Corbi","sequence":"additional","affiliation":[{"name":"National Institute of Physical Education of Catalonia (INEFC), University of Lleida, Lleida, Spain"},{"name":"Human Movement Research Group (HMRG), University of Lleida, Lleida, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7686-6594","authenticated-orcid":true,"given":"Joshua","family":"Colomar","sequence":"additional","affiliation":[{"name":"National Institute of Physical Education of Catalonia (INEFC), University of Barcelona, Barcelona, Spain"},{"name":"Sport, Exercise, and Human Movement (SEaHM) Research Group, University of Vic\u2014Central University of Catalonia, Vic, Spain"},{"name":"Sport and Physical Activity Studies Center (CEEAF), University of Vic\u2014Central University of Catalonia, Vic, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2059-2846","authenticated-orcid":true,"given":"Ernest","family":"Baiget","sequence":"additional","affiliation":[{"name":"National Institute of Physical Education of Catalonia (INEFC), University of Barcelona, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"19","key":"r1","series-title":"J Sports Sci","first-page":"1791","article-title":"Matchplay characteristics of grand slam tennis: implications for training and conditioning","volume":"34","author":"Reid M","year":"2016","unstructured":"Reid M, Morgan S, Whiteside D.
