This book was released on 2016 with total page 132 pages. Available in PDF, EPUB and Kindle. 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

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.

This book was released on 2015 with total page 148 pages. Available in PDF, EPUB and Kindle. 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

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

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: 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.

Download or read book The Effects of Postactivation Potentiation on Subsequent 40 yard Sprint Performance in 16 to 23 year old Male Athletes written by Cody James Yates and published by . 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.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the study was to investigate the effects of an eccentric trap bar deadlift on post-activation potentiation and VJ height. Twenty resistance-trained males ages 18-30 were tested on two different occasions. The first session was used to assess the subject's 3-RM on the trap bar deadlift. The subject then scheduled a second session one week later. The second session consisted of a baseline VJ assessment followed by a 3-RM trap bar deadlift protocol with a VJ test immediately after, 2, 4, and 6 minutes post-exercise. The warm-up was kept the same for both days of protocol testing, with the baseline VJ height occurring after the warm-up and before the trap bar deadlift protocol. Results showed significant differences between VJ heights immediately after and at the 2-minute interval (mean difference = 1.15 in., p = .004, 95% CI [0.30, 2.00] and between the immediately after and the 4-minute interval (mean difference = 1.02 in., p = .015, 95% CI [0.14, 1.90]).

Download or read book Bayesian Cognitive Modeling written by Michael D. Lee and published by Cambridge University Press. This book was released on 2014-04-03 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bayesian inference has become a standard method of analysis in many fields of science. Students and researchers in experimental psychology and cognitive science, however, have failed to take full advantage of the new and exciting possibilities that the Bayesian approach affords. Ideal for teaching and self study, this book demonstrates how to do Bayesian modeling. Short, to-the-point chapters offer examples, exercises, and computer code (using WinBUGS or JAGS, and supported by Matlab and R), with additional support available online. No advance knowledge of statistics is required and, from the very start, readers are encouraged to apply and adjust Bayesian analyses by themselves. The book contains a series of chapters on parameter estimation and model selection, followed by detailed case studies from cognitive science. After working through this book, readers should be able to build their own Bayesian models, apply the models to their own data, and draw their own conclusions.
