Complex Training (CT) is a training method to develop muscular power in athletes. Despite the wide spread utilization of CT in strength & conditioning (S&C) training, there are few training studies conducted to examine the effectiveness of CT within a training cycle. This study examined (1) the effect of a 6-week combined CT of back squat (BS) and countermovement jump (CMJ) on vertical jump performance (VJP) and (2) whether the CT group or traditional strength and plyometric training group (control group) would produce a greater increase in VJP. A parallel two-group, longitudinal design was used for this study. Seven elite male badminton athletes (age: 18.86 ± 1.07 years; body mass: 71.73 ± 9.90 kg; BS Repetition Maximum (RM) to Body Mass ratio [RM:BM]: 1.77 ± 0.19) were matched into a CT or control group. Participants were matched according to playing position (Single or Double players) and relative 1RM BS strength level. Once matched, participants were randomly allocated to either the CT or control group. Participants utilised an individualised rest interval determined during a pilot study. Vertical jump performance variables (peak power, mean power, peak force, mean force, vertical jump height (VJH), peak velocity and mean velocity) were measured for further analysis. There were no significant differences observed in any VJP variables within and between groups at p<0.05. Data trends and moderate-very large effect sizes for key performance variables (d=0.63-1.98) suggests that the CT may be a superior training method over the traditional strength & plyometric training.
