In addition to regular skill-based badminton practice, the RST group performed 30-m all-out running sprints twice per week (2\u20133 sets of 6 \u00d7 30 m, 30 s passive recovery between sprints and 2 min active recovery between sets) over 8 weeks. The HIIT group completed standard badminton training combined with running-based high-intensity intervals prescribed around 90% HR_max. Before and after the intervention, all participants were assessed for aerobic capacity (${\\dot {\\rm V}}$O\n                      <jats:sub>2<\/jats:sub>\n                      max, v${\\dot {\\rm V}}$O\n                      <jats:sub>2<\/jats:sub>\n                      max, first and second ventilatory thresholds), anaerobic power (Wingate peak power (PP), mean power (MP), fatigue index), repeated sprint ability (6 \u00d7 30-m sprints: ideal time (IS), total time (TS), performance decrement), agility (modified T-test), and lower-limb power (countermovement and spike jumps).\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>Results:<\/jats:bold>\n                      All participants completed the study, and no significant baseline differences were found between groups (\n                      <jats:italic>p<\/jats:italic>\n                      &gt; 0.121).
