2024-12-05T22:02:10Z urn:hdl:10459.1/83513 Force-Time Curve Variable Outcomes Following a Simulated Tennis Match in Junior Players Colomar, Joshua Corbi Soler, Francesc Baiget, Ernest Power Serve Fatigue Effects Strength This study examined the alterations induced by a simulated tennis competition on maximal isometric voluntary contraction (MVC), peak rate of force development (PRFD) and rate of force development (RFD) at different stages of contraction. Twenty junior tennis players performed an 80-minute simulated tennis match and two (pre and post) muscular performance tests. Variables tested included MVC, PRFD and RFD at 50, 100, 150 and 200 ms while performing a 90º shoulder internal rotation (IR90), 90º shoulder external rotation (ER90), shoulder horizontal adduction (ADD), shoulder horizontal abduction (ABD) and isometric midthigh pull (IMTP). Serve velocity (SV) was also registered. No significant changes were found regarding MVC, PRFD or SV. Non-significant moderate effect size (ES) towards a decrease in the IR90 RFD at 50 ms could be observed (16%; ES = 0.5) alongside an increase in the ADD and IMTP RFD at 150 ms (-15.8%, - 8.2%; ES = -0.53, -0.54) and IMTP RFD at 200 ms (-13%; ES = -0.54). Results indicate that MVC, PRFD, RFD at different time intervals and SV are unaltered following an 80-minute simulated match, possibly due to insufficient alterations triggered on key factors affecting the tested variables. 2024-12-05T22:02:10Z 2024-12-05T22:02:10Z 2022-06-16T08:43:36Z 2022-06-16T08:43:36Z 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://hdl.handle.net/10459.1/83513 Reproducció del document publicat a https://doi.org/10.52082/jssm.2022.245 Journal of Sports Science and Medicine, 2022, vol. 21, p. 245-252 cc-by-nc-nd (c) Joshua Colomar, Francisco Corbi, Ernest Baiget, 2022 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Medical Faculty of Uludag University
