Stobbie and published by . This book was released on 2012 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The purpose of the investigation was to examine the effects of postactivation potentiation (PAP) elicited from a power clean versus a squat clean on performance measures such as the countermovement vertical jump and 40 meter sprint. College-aged males (N = 9) completed all baseline measurements and testing protocols. Each subject completed a baseline testing session comprised of a lRM power clean, countermovement vertical jump, and 40 meter sprint. Subjects then participated in four additional PAP testing sessions, each separated by one week. Two one-way repeated measures ANOVAs were computed to determine if significant changes occurred between baseline, post-power clean protocol, and post-squat clean protocol measurements. No significant (p ~.058) mean difference was found in vertical jump scores for the college-aged males across the baseline, pre and post measurements. No significant (p >.355) mean difference was found in 40 meter sprint scores across the three protocols for the college-aged males.

Book excerpt: ABSTRACT: The aim of the present study was to investigate the effects of two different squat protocols on post-activation potentiation and VJ. Fifteen resistance trained men were tested on three different occasions, the first which was used to assess 3-RM front squat using the APRE protocol and extrapolating a 1-RM during the last set. The subject then scheduled two testing days which were separated by one week. The first squat protocol was a single repetition of a six second supra maximal eccentric-only front squat to parallel at 110% of 1-RM. The second squat protocol was three full repetitions to parallel at a load equivalent to 3-RM. The warm-up was kept the same for both days of protocol testing, with the establishment of baseline VJ height occurring after the warm-up and before the squat stimulus. VJ height was re-assessed immediately, 2, 4, 6, and 8 min post squat stimulus. VJ scores were not significantly different between the two protocols at baseline, however at each time interval post-stimulus(immediately, 2min, 4min, 6min, and 8min) the supra maximal protocol was shown to elicit a significant (p

This book was released on 2013 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT:The purpose of this investigation was to examine the effects of a depth jump training program versus a hang power clean training program on performance variables such as countermovement vertical jump (CMVJ) and squat jump (SJ) over 6 weeks. Division III female volleyball players (N = 14) completed the pre- and post-testing sessions along with 12 training sessions. The pre-test session was comprised of two trials of a CMVJ and two trials of a SJ. Following the CMVJ and SJ trials, the hang power clean group performed a I-repetition maximum (I-RM) in the hang power clean, while optimal box height was assessed for the depth jump group. The post-test session was comprised of two trials of the CMVJ and SJ. Two 2 x 2 mixed factorial ANOVAs were calculated to analyze the differences between the depth jump training group and hang power clean training group from pre-test to post-test. No significant (p =.26) mean difference was found in the CMVJ between groups. No significant (p =.13) mean difference was found in the SJ between groups. The depth jump training group and hang power clean group both significantly (p =.00) increased in the CMVJ and SJ from pre- to post-test.

Book excerpt: ABSTRACT:The purpose of the present study was to examine the acute effects of traditional and cluster training on post¬ activation potentiation during countermovement vertical displacement. Division III male volleyball players completed two initial testing sessions to identify the maximum countermovement vertical jump (CMVJ), as well as the predicted 1 repetition maximum (1RM) on the hang power clean(HPC) and front squat (FS) exercises. Additionally, the predicted 1RM values were utilized to identify the optimal load for Peak Power in the respective exercises. The four testing days occurred in a randomized-crossover fashion with the participants performing four different exercise configurations comprised of HPC Traditional 4 sets of 3 repetitions with CMVJ recorded after each set, HPC Cluster 4sets of 3 repetitions with 12 s rest between repetitions and CMVJ recorded after each set, and the same occurred for each configuration utilizing the FS exercise. There were no significant mean differences in CMVJ between the 5 testing conditions. Effect sizes were computed comparing CMVJ for each training configuration with the baseline CMVJ. Cohen's d effect sizes for each training configuration compared to baseline were: TR-HPC = moderate effect, CL-HPC = moderate effect, TR-FS low effect and CL-FS = low

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The purpose of the researcher was to examine the effects of power clean and split jerk on acute vertical jump performance. Division III football players (N = 19) completed 2 testing sessions. The 2 sessions consisted of a pre and poststimulus vertical jump test. The stimulus (power clean or split jerk) was randomly assigned at the first session and the other stimulus was completed during. the second session. A 2 x 2 Repeated Measures analysis of varience (ANOVA) was used to determine if differences or an interaction existed between condition (power clean and spit jerk). No significant interactions (p > .05) were found for jump height. A repeated measures t-test was used to determine if differences existed between conditions for relative strength. No significant differences were found between the two movements. No main effect was found between the two movements. Improvements were found in both the exercises on vertical jump but none were significant. The split jerk had an average improvement of .57 in while the power clean group had an average increase of .06 in. The two variables were both effective in having improvements to vertical jump performance after a four minute rest period.

This book was released on 2017 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Postactivation potentiation (PAP) is a physiological adaptation which enables the muscles' contractile properties to optimally perform. PAP is engendered through pre-performance conditioning activities (maximal or submaximal effort), such as a parallel back squat performed prior to a vertical jump test. PURPOSE: The purpose of this study was to determine the effects of postactivation potentiation on subsequent 40-yard sprint performance in 16- to 23-year-old male athletes. Specifically, the effects of hexagonal bar deadlifts (HBD) and weighted sled sprints (WSS) as PAP-loading protocols. METHODS: Thirty-one male subjects (age, 16.9 +/- 1.4 years; height, 180.2 +/- 6.2 cm; weight 83.4 +/- 19.2 kg) participated in this study. Testing sessions include two different visits, a control trial and a PAP-loading protocol trial, separated by ~48-hours, and counterbalanced, allowing each subject to act as their own control. The HBD (n = 8) group performed 4 sets of HBD as the PAP-loading protocol, using body weight (BW) to calculate estimated 1 repetition max (1RM). The WSS (n = 23) group performed 4 sets of WSS for 15-yards, using WSS loads of 25%, 50%, and 50% BW. Both PAP-loading protocols were followed by a 6-minute rest period, and concluded with two laser-timed 40-yard sprint performances. Control trials for both groups consisted of identical time intervals as the PAP trial, with basic active movement utilized instead of the PAP-loading protocol. RESULTS: The PAP trials had faster average 40-yard sprint times (5.35 +/- 0.44 s) compared to the control trials (5.39 +/- 0.39 s) for all subjects. The average difference for the PAP trials (-0.04 +/- 0.10) was statistically significant (p = 0.029). However, there was statistical significance (p = 0.035) between PAP-loading groups, with WSS being the only group to improve in sprint time for the PAP trial. The WSS group improved in 40-yard sprint time for the PAP trial (5.33 +/- 0.45 s) compared to the control trial (5.40 +/- 0.41 s) with a PAP difference of -0.06 +/- 0.10 s for 40-yard sprint time. CONCLUSION: The use of a PAP-loading protocol enhances 40-yard sprint performance, with the use of WSS proving to generate faster sprint times compared to the HBD.

Book excerpt: The purpose of this study was to investigate the acute potentiation effects between unilateral back squats and bilateral back squats on subsequent 20-m sprints, as supported by the literature and establish whether the unilateral squat was an effective stimulus to induce PAP. This study used a random, counterbalanced, and repeated measures design. Five recreational college athletes (age 23.8 ± 3.4) performed two treatment protocols [heavy unilateral squats (HUS), heavy bilateral squats (HBS)] and one control protocol (C) on separate occasions. During the treatment protocols subjects performed a single 20-m baseline sprint and three sprints every 4 minutes, until 12 minutes had elapsed (4, 8, 12-min) following 1 set of 3 reps at 91% 1RM of either HBS or HUS protocol. The control protocol consisted of a single baseline 20-m sprint then a 4-min sit and rest before the three sprints every 4 mins. The data revealed no statistically significant differences between 5-m baseline sprint times and all conditions, F (2.111, 8.443) = 1.345, p = 0.313, and 20-m baseline sprint times and all conditions, F (2.573, 10.291) = 1.798, p > 0.212. In summary, the 20-m sprint performance after 4-,8- or 12min is not affected by the bilateral and unilateral back squat at 91% of 1RM in well-trained subjects. Unilateral and bilateral back squats present similar acute effects after 20-m sprint performance.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine an optimal intensity (percent of five-repetition maximum weight) to perform an activation exercise, to elicit the most effective response of postactivation potentiation (PAP) through the completion of an explosive exercise. A window of opportunity exists after completing a potentiating exercise that, due to a high level of activation and the dissipation of fatigue, should acutely elicit power gains. Fifteen division 1 varsity soccer players (11 female and 4 male) with mean height 169.93 ± 10.95, mean body weight 144.93 ± 27.03lbs, and mean ages of 19.3 ± 0.72 years, completed 2 sessions during the testing protocol; using the first for acquiring baseline data, and the second for experimental testing. Sessions were separated by seven days. During the first session, athletes were assessed for baseline vertical jump heights, and 5 RM back squat. During the second session, subjects performed 5 repetitions at 80%, 90%, and 100% of their 5 RM for 5 repetitions, each followed by a countermovement vertical jump 7.5 minutes thereafter. Results were obtained using the SPSS data processing software and were analyzed through a three way repeated measures ANOVA. The main effect for height was significant (p 0.01) based on within subjects effects. Significant results were found using pairwise comparisons between baseline and 80%, 90%, and 100% PAP protocols (p

Available in PDF, EPUB and Kindle. Book excerpt: PURPOSE: A technique used to enhance acute performance that involves a short, high intensity stimulus followed by a dynamic or isometric movement is referred to as post-activation potentiation (PAP). The acute performances increases have been attributed to both physiological and neurological factors. To date, research on this technique has not investigated the muscular activity during a dynamic vertical jump test of the upper leg muscles. The purpose of this study was to determine how using the PAP technique effects the direct force output of different types of vertical jumps as well as measuring differences with rate of force development curves from baseline outputs.

This book was released on 2020 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The present study was designed to investigate the acute effects of an ascending intensity eccentric Safety Squat Bar (SSB) squat protocol on vertical jump performance. After the maximal strength test by using SSB, twenty trained male students were recruited for two experimental sessions: squat condition (SC) and control condition (CC). In SC, an ascending intensity squat protocol, which combined 40% 1 RM, 60% 1 RM, 80% 1 RM, 100% 1 RM, 120% 1 RM separated eccentric SSB squat, was performed with a three-minute rest interval after warm-up. The vertical jump height was measured at the baseline, after warm-up, and after each SSB eccentric squat. In CC, subjects were asked to seat after warm-up. The vertical jump height was measured at the same time point as SC. A significant difference of vertical jump height was observed after 60% 1 RM eccentric SSB squat (p = .031), after 80% 1 RM eccentric SSB squat (p
