Modern fitness has evolved to incorporate traditional weightlifting with technological advancements. A combination of resistance and plyometric training is used in this intervention to optimize performance. It enables athletes to refine workouts effectively and maximize results through this fusion of these techniques. The current study examined the precise effects of the complex on the bio-motor and physiological responses of field hockey players, which shed light on the potential benefits these techniques may offer to athletes looking to improve their performance on the field. Thirty male field hockey players (mean; age: 19.40 ±1.12 years) were divided into two equal groups at random: the control group (CG) and the complex training group (CM). Three sessions of CM training interventions were conducted each week, with enough recovery time between sessions for each group. All of the chosen bio-motor variables, such as speed and agility and physiological variables, such as vital capacity (VC), VO2 max, and resting heart rate (RHR), have undergone baseline and after the 12-week training intervention evaluations. Since the CG group was practising field hockey every day, they were regarded as an active CG group. The study's findings demonstrated that 12- weeks of CM training intervention significantly improved participants' speed (p<0.01), agility (p<0.01), VC (p<0.01), and VO2 max (p<0.01). There was no discernible difference in the CG (P>.05). There was no discernible difference in RHR between CM and CG (P>.05). As a result of the intervention during the specified period, speed and agility significantly increased, as did VC and VO2 max; however, there was no significant change in RHR. It would be helpful to develop intervention tactics to deal with these problems in the future, as well as replicate studies involving athletes from a variety of sports disciplines beyond field hockey to better understand the fundamental processes that result in optimal performance.
