“…Evidence suggests that PAP may enhance the ability of muscle to produce more force at a faster rate following previous muscle contractions. Over the past decade research has focussed on the effects of PAP on athletic performance using dynamic movements (1,8,13,16,21,24) and isometric maximum voluntary contractions (6,7,9).…”

The purpose of this investigation was to evaluate the postactivation potentiation (PAP) effects of both dynamic and isometric maximum voluntary contractions (MVCs) on sprint and jump performance and establish whether PAP methods could be used effectively in warm up protocols for soccer players. Twelve male soccer players performed 4 warm up protocols in a cross over, randomised and counterbalanced design. In addition to a control warm up, subjects performed dead lift (5 repetitions at 5RM), tuck jump (5 repetitions) and isometric MVC knee extensions (3 repetitions for 3 seconds)as PAP treatments in an otherwise identical warm up protocol. After each treatment the subjects underwent three 10m and 20m sprints 4, 5 and 6 minutes post warm up and three vertical jumps (VJ) at 7, 8 and 9 minutes post warm up. Repeated measures ANOVA showed no significant differences in the first 10m (p=0.258), 20m (p=0.253) sprint and VJ (p=0.703) performance and the average 10m (p=0.215), 20m (p=0.388) and VJ (p=0.529) performance between conditions. There were also no significant differences in performance responses between the strongest and weakest subjects but large variations in individual responses were found between the subjects. The findings suggest that there was no significant group PAP effect on sprint and jump performance following dynamic and isometric maximum voluntary contractions compared to a control warm up protocol. However the large variation in individual responses (-7.1% to +8.2%) suggests PAP should be considered on an individual basis. Factors such as method, volume, load, recovery and interindividual variability of PAP must be considered in the practical application of PAP and the rigorous research design of future studies Postactivation Potentiation, Sprint and Jump Performance 4 to evaluate the potential for performance enhancement.

“…Many researchers (Gullich and Schmidtbleicher, 1996;Gourgoulis et al, 2003;Young et al, 1998) reported that warm-ups of maximal isometric contraction and maximal or high-intensity dynamic exercise can enhance dynamic muscle performances such as jump height. The disagreement of our study and the above previous studies may be due to differences in the following two points.…”

“…Increasing muscle temperature results in improved muscle function and resilience of soft tissues (Yamamoto and Yamamoto, 1993). Previous studies have clarified that prior maximal voluntary isometric contractions (Gullich and Schmidtbleicher, 1996) and submaximal high-intensity contractions (2 repetitions of 20-90% of the 1 repetition maximum (1RM) load (Gourgoulis et al, 2003), 5 repetitions of 5RM intensity (Young et al, 1998)) can increase the rate of force development and jump height during repeated countermovement jumps and drop jumps (Gullich and Schmidtbleicher, 1996).…”

This study aimed to determine the effect of active warm-up by local muscle light exercise and passive warm-up by polarized light irradiation on skin and muscle temperatures and forearm muscle performance (muscle strength, power, endurance, and controlled force-exertion). Ten healthy males performed various grip tests before and after active (local muscle light exercise) and passive (linear polarized nearinfrared light irradiation) warm-ups. An active warm-up involved intermittent gripping exercise (contraction: 1 second and relaxation: 1 second) for 10 minutes using a sponge. A passive warm-up consisted of polarized light irradiation to the forearm (superficial digital flexor) for 10 minutes (irradiation: 5 seconds and rest: 1 second). Skin and muscle temperatures were measured during both warm-ups. Skin and muscle temperatures increased significantly after 5 minutes of local muscle light exercise and after 10 minutes of polarized light irradiation. Temperatures were significantly higher after 6 minutes of local muscle light exercise than after 6 minutes of polarized light irradiation. There were no significant differences of muscle strength, power, and controlled forceexertion before and after either warm-up. Average force outputs in all conditions significantly decreased with exertion time, and at 30, 60, 90, and 120 seconds they were higher in both warm-up conditions than in the non-warm-up condition. In conclusion, both warm-ups may contribute to improve muscle endurance performance in the decreasing force phase.

“…The majority of the research on CT utilized a protocol involving a strength exercise followed by a power exercise [1,3,[6][7][8][9][10][11][12]. However, few studies have been conducted using an initial power exercise instead of the more often used strength exercise in the complex pair [13][14][15].…”

“…In the KSJ group, four to six repetitions of kettlebell swings were performed followed by five consecutive countermovement squat jumps. A recovery period of 3 min between the resistance training exercise (squats/ kettlebell swings) and the plyometric exercise (countermovement squat jumps) was provided to allow for phosphocreatine resynthesis [7,9,19,20] (Figure 4).…”

Purpose. Complex training (CT) involves the coupling of two exercises ostensibly to enhance the effect of the second exercise. Typically, the first exercise is a strength exercise and the second exercise is a power exercise involving similar muscles. In most cases, CT is designed to enhance power. The purpose of this study was twofold. First, this study was designed to determine if lower body power could be enhanced using complex training protocols. Second, this study investigated whether the inclusion of a power exercise instead of a strength exercise as the first exercise in CT would produce differences in lower body power. Methods. Thirty-six recreationally-trained men and women aged 20 to 29 years attending a college physical education course were randomly assigned to one of three groups: squat and countermovement squat jumps (SSJ), kettlebell swings and countermovement squat jumps (KSJ), and a control (CON). Training involving CT lasted 6 weeks. All participants were pre-and posttested for vertical jump performance in order to assess lower body power. Results. Vertical jump scores improved for all groups (p < 0.01). The results also indicated that there were no statistically significant differences between group scores across time (p = 0.215). The statistical power for this analysis was low (0.312), most likely due to the small sample size. However, the results did reveal a trend suggesting that the training improvements were greater for both the SSJ and KSJ groups compared with the CON (by 171% and 107%, respectively) although significance was not reached. Conclusions. Due to the observed trend, a replication of this study with a greater number of participants over a longer period of time is warranted.
