Abstract
This study investigated whether the barbell hip thrust (BHT) enhanced change-of-direction (COD) speed measured by the 505 COD speed test. Forty recreationally trained individuals completed three sessions. Session 1 included one-repetition maximum (1RM) BHT testing to measure absolute and relative strength. Sessions 2 and 3 involved two counter-balanced conditioning activities (CAs): 3 sets × 5 repetitions of the BHT at 85% 1RM and a control condition (CC; 6 min rest). The 505 COD speed test was performed 5 and 2.5 min pre-CA, and 4, 8, 12, and 16 min post-CA in each session. A 2 × 5 repeated-measures ANOVA (p < 0.05) calculated performance changes across time post-CA. A 2 × 2 repeated-measures ANOVA analyzed best potentiated performance. Partial correlations controlling for sex calculated relationships between the 1RM BHT and 505 COD speed test percent potentiation. There was a significant main effect for time (p < 0.001), but not for condition (p = 0.271) or condition × time (p = 0.295). There were no significant correlations between 1RM BHT and potentiation. The 85% 1RM BHT did potentiate the 505 4–16 min post-CA but no more than the CC. Nonetheless, a heavy BHT could be programmed prior to COD drills as COD speed could be potentiated and performance improved in men and women.
Highlights
Agility is an essential quality of many athletes and has been defined as an action that features an initiation of body movement, change-of-direction (COD), or rapid acceleration or deceleration in response to a stimulus [1]
Any acute improvements to the 505 COD test time that resulted from the use of the barbell hip thrust (BHT) as a conditioning activities (CAs) were no different from a control condition (CC) of 6 min rest
The current study revealed that 3 sets × 5 repetitions of BHT with 85% 1 included one-repetition maximum (1RM) was able to enhance
Summary
Agility is an essential quality of many athletes and has been defined as an action that features an initiation of body movement, change-of-direction (COD), or rapid acceleration or deceleration in response to a stimulus [1]. In addition to the cognitive component, the physical component of agility is termed COD speed. COD speed involves factors such as the athlete’s sprint technique, strength, and power [1]. Explosive and decisive COD movements are undertaken within the match-play of many individual and team-based sports and are often central to success. Different training methods have been used to improve COD speed. This includes sprint training, plyometrics, specific COD drills, the flywheel paradigm, and resistance training [2,3,4,5]. One training method for acute changes in COD speed that has received limited analysis involves post-activation performance enhancement (PAPE), for field- or court-based sports
