This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power output in sport is one of the most important factors in athletic performance. Strength and conditioning coaches commonly use the countermovement jump (CMJ) and drop jump (DJ) to assess power in their athletes, and they often utilize plyometric training to improve power. The purpose of this study was to examine the effects of three different plyometric loading conditions on the CMJ and DJ, with regards to braking impulse (BI) and reactive strength index (RSI). The three loading conditions were bodyweight loading (BWL), Traditional Plyometric Loading (TPL), and Accentuated Eccentric Loading (AEL). Twentyeight resistance-trained individuals completed the CMJ testing, and 25 completed the DJ testing. Data was analyzed using a oneway repeated measures ANOVA, and there was a significant difference (p

This book was released on 2021 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of different rest intervals (1, 3, and 5 minutes) on countermovement jump variables (jump height, peak power, and rate of force development) was assessed in experienced collegiate jumpers (n = 14; 20.42 ± 1.55 years; 64.74 ± 10.10 kg). The participants completed four testing sessions in which they completed maximal countermovement jumps separated by a randomized rest interval (1, 3, and 5 minutes). A factorial repeated measures analysis of variance (RMANOVA) demonstrated a statistically significant mean difference when comparing the change in jump height from jump 1 to jump 2, versus the change in jump height from jump 3 to jump 4 (p = 0.044). Furthermore, a statistically significant mean difference was shown comparing the change in peak power (p = 0.049) from jump 1 to jump 2 versus jump 3 to jump 4. Based on a one-way repeated measures analysis of variance, a statistically significant mean difference (p = 0.043) for the total change in jump height (jumps 1-4) was found comparing the one minute versus the three-minute rest intervals. A statistically significant mean difference (p = 0.021) was found comparing the total change in peak power (jumps 1-4) for the one-minute rest interval versus the five-minute rest interval. Based on the results of the study, varying the rest intervals had a statistically significant impact on jump height and peak power.

Book Synopsis Effect of Increasing External Loads on Countermovement Jump Landing Kinetics Between NCAA DI Women's Soccer and Gymnastics on Land Vs in Water by : Paul Bryan Beachem IV
Download or read book Effect of Increasing External Loads on Countermovement Jump Landing Kinetics Between NCAA DI Women's Soccer and Gymnastics on Land Vs in Water written by Paul Bryan Beachem IV and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to compare the effect of differing loads on landing kinetics on land, and in aquatic conditions. Twenty four NCAA DI athletes volunteered for this study twelve female soccer players and twelve female gymnasts. Participants performed three jumps with four differing external loads in both land and aquatic environments. External loads were body weight (BW), BW*1.1, BW*1.2, BW*1.3 and applied via a weighted vest. All external loads for both conditions were added based upon participants BW on land. Kinetic measures were peak force, rate of force development, and impulse of the landing phase of the plyometric countermovement jump. Data was collected via waterproof force-plate. Results were analyzed using a three-way repeated measures 2x2x4 ANOVA. There was no significant difference in any result based on sport. Aquatic environments reduced peak impact by 50.7%, rate of force development by 53.5%, and impulse by 38.6%. Increasing external load did not produce significant differences for impact peak force or rate of force development, but did produce significantly higher impact impulse for land based jumps (p=0.000). In an aquatic environment increasing load produced significant differences in all three kinetic values. The results for environment agree with previous studies. The results for loaded aquatic countermovement jumps in this study show increased landing kinetics over unloaded aquatic jumps, and decreased landing kinetics over unloaded land jumps. Adding external load in aquatic environments may utilized to increase landing kinetics, while remaining under kinetic values of land based plyometrics.

Download or read book The Effect of Four Different Rest Strategies on Repetitive Bouts of Vertical Countermovement Jump Performance written by Samuel Santich and published by . This book was released on 2018 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Intra workout and intra set rest and recovery are not as prevalent in modern research as variations in volume or intensity. However, that does not mean that rest strategies are not important factors to be considered when planning a training plan. The purpose of the study was to examine the effects of four rest strategies on vertical jump height, peak power, and cumulative power over multiple jumps. Data were collected from 18 resistance and power trained males, age 18 - 30, (mean age 24, mean weight 81.85 kg). Participants had a total of 5 sessions, one baseline session, and one session per rest strategy. Each session participants completed a standardized warm up, then, jumped for five sets of three jumps interspersed with the rest strategy of the day. There were no significant differences amongst the rest strategies for peak or cumulative power. For vertical jump, sitting for three minutes and walking for one minute both produced significantly greater vertical jump heights than walking for three minutes (139.27 ± 20.42 cm and 139.66 ± 21.62 cm respective, compared with 131.48 ± 21.41 cm of walking for three minutes). To optimize vertical jump recovery, athletes should have a longer, passive rest, or, a shorter, low impact rest.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the study was to determine if an isometric quarter squat was sufficient to elicit postactivation potentiation (PAP) in a countermovement jump (CMJ) for recreationally trained individuals (n = 22). The isometric quarter squat conditioning stimulus consisted of three sets of six second maximal voluntary contractions against a custom made apparatus. The conditioning stimulus was designed to acutely enhance CMJ performance by stimulating PAP, in turn improving indicators of CMJ performance which included eccentric rate of force development (ERFD), mean rate of force development (MRFD), peak rate of force development (PRFD), reactive strength index (RSI), and peak power (PP). CMJ performance was tested at one, five, ten, and fifteen minutes post-conditioning stimulus to identify the optimal recovery time for optimal performance. Statistical analysis was carried out using a two-way repeated measures analysis of variance (ANOVA) and no significant or meaningful change was found in ERFD, MRFD, PRFD, RSI, or PP. The overall power was small for all variables suggesting that the ability of the current study to observe an effect that might have existed was very unlikely. Effect size was also small in all variables suggesting that the change pre to post-testing was not meaningful. Some critical factors that may have contributed to the results included the individual's ability to potentiate, body positioning during conditioning stimulus, and level of conditioning of subjects.

This book was released on 2009 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The purpose of the current study was to examine the acute effects of antagonist static stretching on vertical jump performance. Resistance trained males (N 31) participated in the study. Each subject performed four trials during each of static squat and countermovement (CMJ) vertical jumps during each session in this repeated measures design. Subjects jumped before treatment, immediately after treatment, at 5 mm post-treatment, and at 15 mm post- treatment. Subjects performed two sessions of testing, one featuring a static stretching treatment where the antagonist muscles for the vertical jump were stretched, the other a control. A significant (p .05) main effect was found for time, where all vertical jumps performed immediately after treatment and at 15 mm post-treatment were significantly (p

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate alterations in lower extremity kinematics during the landing phase of a countermovement jump when performed in different environments and under multiple external loads. Twenty-four NCAA Divison I collegiate female athletes performed 12 countermovement jumps on land and 12 jumps in water, submerged to the xiphoid process, for a total of 24 jumps. Within each environmental condition, four loading conditions of three jumps each were performed using a weighted vest: Unloaded, 10%, 20%, or 30% of body mass. The hip, knee, and ankle angles were measured as the smallest angles between the major body segments (trunk, thigh, shank, and foot) in the sagittal plane using the digital goniometer tool from Kinovea video analysis software at the point of maximum knee flexion. Larger angles indicated decreased joint flexion and smaller angles indicated increased joint flexion. The mean hip, knee, and ankle angles were significantly greater for the jump landings in water compared to on land, regardless of load (133.7℗ʻ vs. 113.9℗ʻ, 119.5℗ʻ vs. 107.5℗ʻ, and 91.7℗ʻ vs. 85.6℗ʻ, p
