The Acute Effects of Prior Dynamic Resistance Exercise Using Different Loads on Subsequent Upper-Body Explosive Performance in Resistance-Trained Men

Abstract

The purpose of this study was to determine if explosive upper-body performance could be improved when it was preceded by conditioning contraction protocols that incorporate resistance exercise. Providing that performance was enhanced, it was also the intention to determine the optimal conditioning contraction load for enhancing performance. Eight recreationally trained men completed 4 experimental sessions. Each session consisted of a warm-up, 3 bench press throws (pre), a conditioning protocol, and 3 bench press throws (post). The different conditioning protocols consisted of 5 bench press repetitions using 100, 75, or 50% of 5 repetition maximum (5RM) strength. The fourth protocol, in which no repetitions were completed, acted as a control. Participants performed each conditioning protocol on a different day, and the order in which the protocols were performed was randomized. Average power, assessed during the bench press throws, was determined for the starting segment and the end segment (point of bar release) for each throw. Comparisons in average power, for each segment of the bench press 1RM, were made between the pre- and postconditioning protocol bench press throws. None of the conditioning protocols had an effect on bench press throw performance in either of the 2 segments of the movement. The results suggest there is no performance advantage when explosive upper-body movement is preceded by resistance exercise of varying loads. Alternatively, the performance of a set of resistance exercise did not compromise explosive upper-body performance. Considering this, training methods that combine both resistance exercise and plyometric-like exercise may offer a practical and time-efficient training system.

Effects of different re-warm up activities in football players' performance

“…The mode of the conditioning exercise, intensity, recovery time, type of contraction as well as the players’ training status will determine an individual response in either potentiating a subsequent exercise task or inducing fatigue [38, 39]. Under this scope, research suggests that, generally, post activation potentiation mechanisms WU effects are more efficient in well trained individuals rather than in recreational athletes, probably due to their capacity to recruit more motor units at a higher firing rate during the conditioning exercise [40].…”

Postactivation potentiation in elite young soccer players

“…Only two studies verified different intensities without dynamic actions to cause PAP. Brandenburg (2005), using the bench-press exercise with different intensities (five repetitions at 100% 5RM, 75% 5RM, and 50% 5RM), and control condition, after 5-min recovery intervals, with evaluation of three repetitions of ballistic bench-press exercises before and after different intensities. The author did not find significant differences between the potentiation protocols, a result similar to the present study.…”

A systematic review of the effects of upper body warm-up on performance and injury

“…This yielded level 1 evidence of the positive effects of high-load dynamic warm-up on strength12 16 20 and power15 17 19 outcomes, as well as level 2 evidence of these positive effects on flexibility12 20 and delayed onset muscle soreness (DOMS)12 20 outcomes. Level 3 evidence was found regarding physiological12 15 20 21 and passive indicator12 outcomes.…”

“…Only one study investigated high-load dynamic warm-ups—five reps of 50%, 75% and 100% 5 repetition maximum (RM) bench press19—but did not report positive strength or power outcomes, suggesting that high-load dynamic warm-ups can be recommended for enhancing strength or power outcomes regardless of the specific mode used. Future investigations should focus on determining the optimum load and duration of high-load dynamic warm-up for maximum performance enhancement.…”
