Introduction: Alternating a resistance exercise with a plyometric exercise is referred to as “complex training”. Purpose: This study aimed to compare the acute post-activation performance enhancement (PAPE) effects of the Barbell Back Squats (SQ), Drop Jumps (DJ) and Complex Training Method (CT) in terms of vertical jump height (VJ) and Reactive Strength Index (RSI) in physically active individuals. Methods: Nineteen participants (11 male and 8 female) who resistance train at least 3 times/week volunteered this study. Participants performed three experimental sessions namely; SQ, DJ and CT loading sessions with 48 hours interval with a randomized, crossover study design. SQ was performed roughly at 90 % of 1 Repetition maximum (1 RM) of the participants with three repetitions (3RM). In DJ session, participants performed 2 sets of 10 drop jumps with 3 min rest whereas in CT sessions, participants performed 5 drop jumps followed by 3RM back squats. Participants were tested for VJ and RSI before and 8 minutes after each treatment. Results: Within-group differences (pre vs. post-intervention) were only present for RSI performances for the CT group (p=0.004). No between-group differences (i.e. SQ, DJ and CT) were evident for VJ (p=0.93) and RSI (p=0.87) performances respectively. Conclusion: These findings demonstrated that none of the loading protocols with above mentioned exercises and methods have any detrimental or improving effects on VJ height and RSI for physically active individuals who joined this study. This study also showed that SQ, DJ exercises and CT method can be used interchangeably and safely to avoid training monotony during longer training periods for chronic adaptations.
