Understanding how to optimize training for every individual is the goal for all exercise specialists. The current study looked into the effects of plyometric development drills within differently trained populations on anaerobic peak power, average power, end power, and fatigue index. Purpose: This research was intended to explore the potential for untrained individuals to benefit positively from plyometric training in peak power, end power and average power proportionally equal to trained individuals. Methods: Participants were recruited both verbally and electronically. Recruited participants (n = 11, age = 21.3 ± 0.6 years, weight = 69.4 ± 15.0 kg, height = 170.3 ± 9.2 cm, body fat = 20.2 ± 5.8%) attended a total of three sessions. Participants were separated into two groups: trained or untrained. Training status was defined as completing at least two sessions a week of resistance training for at least 20 minutes each session, for 12 continuous weeks prior to participating. All participants completed two 30 second Wingate tests (WAnT) to test peak power, average power, end power and fatigue index. One test was preceded by a dynamic warm-up and plyometric drills (Plyos), while the control only included the dynamic warm-up (No Plyos). Results: Multiple mixed-method analysis of variances (ANOVA) were conducted using SPSS. It was found that the use of plyometrics significantly increased peak power (F1,9 = 13.07, p < 0.05, Plyos =959.6 ± 245.9 W, No Plyos = 884.5 ± 235.6 W) and anaerobic capacity (F1,9 = 5.37, p = 0.046, Plyos = 7.78 ± 1.513 W/kg, No Plyos = 7.436 ± 1.507 W/kg). In contrast, average power (F1,9 = 3.98, p > 0.05) and end power (F1,9 = 0.08, p > 0.05) were not significantly affected. Conclusion: Plyometrics prior to power testing improved peak power performance for both trained and untrained individuals.
