This book was released on 2018 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study compared the effects of two conditioning exercise types on subsequent countermovement jump performance. Fifteen male collegiate rugby players (age 21.1 ± 2.3) completed two experimental protocols in a randomized order. The first protocol consisted of 3 sets of a 5 second maximal isometric half squat (ISO), with 1 minute rest intervals between sets. The second protocol consisted of 2 sets of 5 depth jumps (DJ) at a platform height which was determined by the athletes' reactive strength index (RSI). These methods were each adapted from prior literature where post-activation potentiation (PAP) was achieved, in order to determine the relative timing and amplitude of the effect using a repeated measures design. Results of a two-way ANOVA for CMJ height reveal a significant main effect of time ((F[5,60] = 8.291, p
Download or read book Manipulating a Conditioning Activity to Enhance Potentiation and Its Application to Jumping and Sprinting Performance written by Mathew W. O'Grady and published by . This book was released on 2017 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Post-activation potentiation (PAP) is the phenomenon where contractile history of a muscle may acutely increase voluntary performance of future contractions that are biomechanically similar (72). In order to exploit the PAP phenomenon, a conditioning activity (CA) is performed to enhance the performance of a subsequent skill. Throughout the literature, a common example of a CA is sets of heavy-loaded squats in order to potentiate subsequent jumping (31,33,39,57,83,116,151,163) or sprinting performance (15,28,39,99). Post-activation potentiation can be used either in a warm-up to acutely enhance performance for competition, or used within a resistance training session to enhance speed-strength, with the intention of producing a greater training stimulus for chronic adaptations. The major issue with the PAP literature is the inconsistent results from study to study. There are many examples within the research that show the positive effects of PAP (44,54,57,62,83,102,133,163), whilst many others have failed to find any increase in performance (42,47,56,81,112,123,141). The results have been inconsistent as the methodology between studies has varied dramatically. These differences include the warm-up used prior to testing sessions, changes in the type of CA (30,54,163), the intensity or load of the CA (19,21,33) and the rest period allocated between the CA and the performance of the skill. Furthermore, it seems that certain individuals respond better to a CA, with most of the literature suggesting that participant strength has a positive correlation with a potentiating response (15,31,44,116,128,129,163). Due to the vast differences in methodologies used throughout the potentiation literature, it is hard for coaches to identify the best practice in order to elicit a positive potentiating effect. Therefore, four studies were designed to address these current gaps within the potentiation literature in order to establish the best methodology to elicit a potentiating response. The first study sought to investigate whether a heavy half-squat CA could further improve jumping after an individualised optimal warm-up. The second study of this thesis investigated the acute response of two different CA strategies. The third study of this thesis compared different volumes of plyometric CAs (rebound jumps) to a CA involving heavy half-squats and assessed the effect each had on potentiating CMJ and sprinting performance. The final study of this thesis firstly aimed to investigate the effect of three different types of half-squat CAs had on potentiating CMJ performance. This study also aimed to explore why certain individuals respond positively to a CA, whilst others respond in a negative manner." -- Taken from Abstract.

Download or read book Effects of an Upper Body Conditioning Stimulus on Lower Body Post activation Potentiation written by Grant Laskin and published by . This book was released on 2020 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: One strategy to improve strength and power development in athletes is by implementing complex training, where both high-load and plyometric movements are alternated one after the other throughout a workout. Research suggests that when a high-load, low-velocity conditioning stimulus (CS) is performed just prior to a biomechanically similar plyometric movement, the performance of the plyometric movement is acutely enhanced in a phenomenon called post-activation potentiation (PAP). Despite the positive influence PAP can have on power production, research has only investigated the existence of PAP when comparing biomechanically similar movements. PURPOSE: To determine if an upper body CS can elicit a PAP response in a lower body plyometric exercise and to investigate the optimal time course for PAP between an upper body CS and lower body plyometric exercise. METHODS: Eight (8) resistance-trained males (23.5 ± 2.7 y; 177.5 ± 3.2 cm; 81.7 ± 5.8 kg) participated in the study. Participants performed one set of three countermovement jumps (CMJs) before (pre-CS) and three sets of three CMJs after (post-CS) an upper body CS. Muscle activation in the vastus lateralis, gastrocnemius, and gluteus maximus were compared between pre-CS and the three post-CS conditions using surface electromyography. Changes in jump height, work, power output, and rate of force development (RFD) during the early and late stages of the CMJ take-off between the conditions were analyzed using a force plate. A repeated-measures MANOVA with LSD post-hoc testing was used to determine differences using SPSS. The level of significance was set at p

Available in PDF, EPUB and Kindle. Book excerpt: Muscle contraction has been the focus of scientific investigation for more than two centuries, and major discoveries have changed the field over the years. Early in the twentieth century, Fenn (1924, 1923) showed that the total energy liberated during a contraction (heat + work) was increased when the muscle was allowed to shorten and perform work. The result implied that chemical reactions during contractions were load-dependent. The observation underlying the “Fenn effect” was taken to a greater extent when Hill (1938) published a pivotal study showing in details the relation between heat production and the amount of muscle shortening, providing investigators with the force-velocity relation for skeletal muscles. Subsequently, two papers paved the way for the current paradigm in the field of muscle contraction. Huxley and Niedergerke (1954), and Huxley and Hanson (1954) showed that the width of the A-bands did not change during muscle stretch or activation. Contraction, previously believed to be caused by shortening of muscle filaments, was associated with sliding of the thick and thin filaments. These studies were followed by the classic paper by Huxley (1957), in which he conceptualized for the first time the cross-bridge theory; filament sliding was driven by the cyclical interactions of myosin heads (cross-bridges) with actin. The original cross-bridge theory has been revised over the years but the basic features have remained mostly intact. It now influences studies performed with molecular motors responsible for tasks as diverse as muscle contraction, cell division and vesicle transport.

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.
