Acute effects of 'composite' training on neuromuscular and fast stretchshortening cycle drop-jump performance in hurling players 'Composite' training and hurling 2 Abstract 'Composite' training is a term developed by the authors and defined as the combination of a plyometric exercise with an explosive activity such as a sprint run, performed as a 'combined repetition' / session. The purposes of this study were to investigate the acute effect of a 'composite' training session on neuromuscular and fast stretch-shortening cycle bounce drop-jumps (BDJ) in hurling players' immediately, post-session and post 7-days of recovery. Eight hurling players first completed a DJ test to identify individual BDJ drop height, followed seventy-two hours later with a single 'composite' training session. Three-repetition maximum (3RM) back squat strength, BDJ, countermovement jump (CMJ) and sprint performance testing were performed 10 mins pre-and immediately post-session and 7-days post-session. An ANOVA reported a significant decrease in CMJ measures (height, velocity and eccentric rate of force development (ECC-RFD)) and sprint performance from pre-to post-session (p ≤ 0.05). Moreover, a significant increase was evident for CMJ performance (height and power), sprint performance (5 and 20 m), 3RM back squat strength and BDJ performance (RSI and height) from post-session to post 7-days recovery (p ≤ 0.05). Pair-wise comparisons indicated that absolute and relative 3RM strength significantly increased from pre-session to post 7-days (absolute 3RM: p = 0.0001; relative 3RM: p = 0.01). The findings indicate that 'composite' training results in an immediate decline in CMJ measures post-session possibly due to acute muscle fatigue and super compensation augments maximum lower limb strength following 7days of recovery.
