All groups continued their usual badminton practice (2\u20133 sessions\/week; 75\u201390 min\/session). Over 6 weeks, only the intervention groups completed an additional supervised plyometric session once per week (25\u201330 min; 72 explosive actions), whereas the control group performed no additional plyometric\/strength sessions. Repeated-measures ANCOVA with maturity offset as covariate assessed pre\u2013post changes in overhead medicine ball throw, seated chest pass, plyometric push-up height, and smash speed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Significant time effects were observed for all outcomes (p &amp;lt; 0.001; \u03b7\n                      <jats:sup>2<\/jats:sup>\n                      p = 0.737\u20130.954).

Time \u00d7 group interactions were also significant for overhead throw (p &amp;lt; 0.001; \u03b7\n                      <jats:sup>2<\/jats:sup>\n                      p = 0.918), chest pass (p &amp;lt; 0.001; \u03b7\n                      <jats:sup>2<\/jats:sup>\n                      p = 0.840), push-up height (p &amp;lt; 0.001; \u03b7\n                      <jats:sup>2<\/jats:sup>\n                      p = 0.718), and smash speed (p &amp;lt; 0.001; \u03b7\n                      <jats:sup>2<\/jats:sup>\n                      p = 0.950). Post-hoc analysis showed PLYOgen and PLYObad improved overhead throw and smash speed more than control, with PLYOgen also presenting greater values than control in push-up height.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Both plyometric approaches enhanced upper-limb explosive performance, with biological maturation significantly moderating training responsiveness.
