Objective The purpose of this study was to explore the effects of an 8-week drop jump (DJ) training program at varying heights on lower limb strength, anaerobic power, and change of direction (CoD) abilities in elite female Chinese wrestlers. Methods The drop jump (DJ) training program was conducted at varying heights of 20, 40, 60, and 80 cm. The study involved 40 elite female wrestlers who were divided into five groups respectively: Control, DJ20, DJ40, DJ60, and DJ80. Participants engaged in an 8-week structured training program that incorporated drop jumps at the assigned heights for each group. Results The results demonstrated significant enhancements in explosive strength and anaerobic power, particularly with DJ40 to DJ60 (d = -2.48 to -5.54), and in CoD performance across all DJ groups (d = 1.07 to 5.25), showcasing a dose-response effect. Conclusions Optimal training effects for lower limb strength and power were found at drop jump heights of 40-60 cm, while heights of 60-80 cm yielded the most significant improvements in CoD performance. This highlights the specificity of DJ training heights in enhancing athletic performance among elite female wrestlers.
