Background: Taekwondo is a powerful sport in which the maximal performance relies on anaerobic metabolism and explosive power. Aims: to determine the dedication of different strength and power training programs (off-season, pre-season and in-season) to lower limb performance and physiological modulation during a 20-week training period. Methods: Eight male collegiate taekwondo athletes completed 20-week systemic training programs divided into a linear training mesocycle (general conditioning, muscular recruitment, and hypertrophy) from 1 to 12 weeks, and two microcycle (maximum strength , explosive power, agility, speed) from 13 to 20 weeks in periodized fluctuation. Subjects were evaluated biochemical index, forearm total vascular occlusion test and muscular stiffness test six times during Training program: at the beginning (week 0, date1, T1), in the middle (week 2, Date 13, T2; week 8, Date 55, T3; week 14, Date 97, T4; week 18, Date 125, T5) and at the end (week 21, Date 143, T6) of the training program. Squat jump (SJ), countermovement jump (CMJ) and continuous jump bent leg (CJb) were tested before and after the systemic strength training period. Results: There were significantly increasing in the SJ (7.8(2.7)%), CMJ (18.3(4.1)%) and CJb (8.7(4.7)%) after the totally training programs. Training increased creatine kinase levels from T1 to T4 (327.8%) and recovered at T6 (99.4%). Muscle damage and muscular recruitment function recovered at T6 after taper. Conclusion: The conjunction of systemic periodized 20 weeks training programs would increase lower limb performance and strengthen neuromuscular controlling in taekwondo athletes.
