Journal of Sports Science and Physical Education 7(1): Received: 3 January 2018, Accepted: 10 February 2018 – Weightlifting is a sport that requires both dynamic strength and power. Until today, weightlifting coaches are still exploring different training modes in an attempt to enhance both muscular strength and power of the competitive weightlifters. Research has shown that the use of the “right” training method could further provide knowledge on such effect for competitive weightlifters (Storey & Smith, 2012). Thus, the aim of this study was to investigate the effects of using the complex training method (applicable to weightlifting) compared to traditional resistance training on muscular strength among male competitive (state level) weightlifters. Seventeen male competitive weightlifters were randomly assigned into 2 groups: experimental group (Complex Training; n = 9), and control group (Traditional Resistance Training; n = 8). All participants trained for 6 weeks (2 sessions per week) with the total training volume equated between both groups. Participants underwent pre-test and posttest including the anthropometric measurements (height, body weight, and body fat) and lower body strength (isokinetic strength test) parameters. The results showed that there was a significant increase from pre- to post-test in knee extension peak torque t(8) = -4.22; p = .003 and t(7) = -5.37; p = .001, and knee flexion peak torque t(8) = -5.98; p = .001 and t(7) = -4.20; p = .004 in experimental and control groups respectively. No significant difference (p > .05) was observed in knee extension peak torque (22.9 ± 16.3 versus 13.9 ± 7.3) and knee flexion peak torque (11.4 ± 5.7 versus 10.1 ± 6.8) improvements between the complex training group and control group respectively at post-test. In conclusion, the use of complex training method showed similar effects in enhancing muscular strength with traditional resistance training after 6 weeks of intervention.
