Book excerpt: The ability to throw at higher velocities with proper mechanics is very advantageous for baseball pitchers to increase performance and decrease injury risk. Pitching utilizes the movement of energy through the kinetic chain, wherein momentum is generated by the proximal core segments of the body and transferred to the distal segments of the throwing shoulder and elbow to produce ball velocity. Medicine ball throws (MBT) have been used as a training method for rotational throwing and striking athletes to improve core strength and power. Rotational MBT are sport-specific for baseball pitching because of the similar explosive sequential muscle activation of the pelvis, torso, and arms. The purpose of this study was to investigate the effects of a side-rotational MBT exercise on pitching biomechanics and ball velocity when performed immediately prior to pitching as a method of post-activation potentiation (PAP). High school,college, and professional aged pitchers (n = 6, age 19.5 ± 3.6 years) were randomly assigned to MBT and control (CON) groups. Both groups threw five pre-trial and five post-trial maximal effort fastballs, with the MBT group performing one set of six side-rotational MBT at maximum effort in between the pre and post-trials while the CON group rested. All pitching trials were recorded by a three-dimensional motion capture system at 240 Hz, from which five temporal, four kinematic, and three kinetic variables were calculated. A 2 x 2 mixed ANOVA for each dependent variable was used for comparisons between and within groups. There were significant interactions between groups and time for peak trunk rotational velocity (p = .049), peak elbow extension velocity (p = .014), and maximum external rotation torque (p = .042). These results may warrant further research into MBT as a method for warming up and eliciting a PAP response for pitching.

Book Synopsis A Kinematic and Kinetic Comparison of Baseball Pitching Mechanics Influenced by Stride Length by : Ryan Lewis Crotin
Download or read book A Kinematic and Kinetic Comparison of Baseball Pitching Mechanics Influenced by Stride Length written by Ryan Lewis Crotin and published by . This book was released on 2013 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current workload metrics and ball velocity records have been dubious in identifying clear overuse mechanisms of injury, raising greater interest in pathomechanics research, where most work has been focused on the critical instant, spanning the throwing arm's acceleration and deceleration phases. Since throwing arm kinematics and kinetics are lowest from the onset of the pitching delivery, the majority of research neglects biomechanical interactions occurring before stride foot contact (SFC). In light of this, the current dissertation established a new framework of study, examining stride length effects on baseball pitching performance, where lower extremity joint dynamics from the onset of the delivery through to ball release, ground reaction force profiles, as well as global pelvic and trunk kinematics are anticipated to be affected by altered propulsion and bracing biomechanics. The dissertation investigated the effect of stride length through seven studies. To determine an overall representation of stride length impacts on the kinetic chain and temporal events, linear and angular momentum analyses were performed for the total body and throwing arm. Trunk-throwing arm momentum exchanges were represented by momentum compensation ratios to identify the proportion of the throwing arm to the total body momentum (contributed mostly by the trunk). In the results, stride length affected the instant of SFC, as longer strides increased single support generation and abbreviated the duration of the brace-transfer phase. Momentum relationships most consequential to phase time affects entailed greater leading axis momentum for pitchers with longer strides, while greater transverse momentum later in the pitching delivery was seen with shorter strides, which had been considered compensatory for reduced propulsion prior to SFC. The second study differentiated propulsion and bracing ground reaction force profiles, as vertical weighting, anterior-shear forces and their normalized impulses were greater for longer strides prior to SFC, while thereafter, the drive foot applied braking forces in tandem with the stride leg. Shorter strides minimized drive foot posterior-shear force, maintained propulsion after SFC in double support, and applied peak vertical weighting of the stride leg near ball release. Affected ankle dynamics were featured in the third study, which related to the aforementioned differences in ground reaction force profiles. Longer stride's drive ankle applied greater propulsion dynamics prior to SFC with closed-chain dorsiflexor moments thereafter to assist braking and landed the stride foot with greater heel-strike.^Shorter strides maintained drive ankle propulsion dynamics after SFC, minimized hind ankle braking, landed more in toe-strike, and required greater stride ankle braking dynamics during acceleration. Bilateral knee flexion-extension dynamics were investigated in succession where greater propulsive dynamics during generation and greater hind leg extension kinetics were found with longer strides, believed to increase inertial and frictional effects in braking effects. Maintained propulsion after SFC, greater stride knee flexion and extension power occurred with shorter strides. In the fifth study, femoral-acetabular hip dynamics revealed greater internal rotation and abduction, which facilitated greater maximum drive hip kinetics in extension prior to SFC with longer strides. Following SFC, longer strides generated greater stride hip extension power in braking and eccentrically slowed internal rotation in greater stride hip flexion. Longer strides improved stride hip biomechanics to better moderate internal pelvic rotation toward home plate and added stability, throwing from a lowered position within a wider base of support. Shorter strides revealed greater stride hip extension, believed to elevate the center of mass within a narrower base of support, reducing stability to most likely minimized braking to maintain drive hip propulsion kinetics and expedite internal pelvic rotation in double support after SFC. The sixth study, proximal segment kinematics were examined as longer strides anterior pelvic rotation, forward trunk flexion, upward pelvic rotation, non-dominant trunk bending, as well as internal rotation kinematics of the trunk and pelvis were greater prior to SFC. Thereafter, the kinematics mentioned above were greater for shorter strides. Lastly, pelvic-trunk separation angles and proximal plyometric effects denoted stride length influences upon the transverse pelvic-trunk rotational couple.^Greater separation occurred prior to SFC with longer strides with peak separation found shortly thereafter. Shorter strides further counter-rotated the pelvis away from home plate at the onset of the pitching delivery and also coordinated peak separation later in the delivery near the acceleration phase, producing greater proximal plyometric effects at BR, evidenced by a 3. 3-fold faster internal rotation velocity of the trunk than that of the pelvis. Our exploration drew several overall conclusions: 1) Stride length is critical to event timing between the onset of delivery and the beginning of brace-transfer phase, 2) Longer strides increase drive leg propulsion dynamics prior to SFC and initiates tandem braking effects (drive and stride leg braking dynamics) thereafter in slowing trunk angular momentum prior to the critical instant, 3) Pitchers with longer strides tend to release each pitch in greater double support (greater drive and stride foot weighting into the ground), 4) Shorter strides maintain propulsion in double support following SFC, minimizing drive leg braking, delaying stride leg braking and increasing transverse trunk momentum prior to the critical instant, and 5) Shorter strides have a greater tendency to be pathomechanic, as elevated internal rotation velocities of the trunk near the critical instant appear to disrupt transverse momentum transfer to the throwing arm. Performance outcomes were found statistically equivalent between conditions suggesting that stride length and accompanied biomechanics can be highly variable in skilled pitchers without impacting competitive performance. Since most stride lengths are attained through maintenance of peak ball velocity, many desired strides may be flawed, susceptible to exertion, and encourage throwing arm pathologies. This work draws attention to the need for further work exploring stride length optimization, intimating a rationale that adjusting stride length as a percentage of body height mitigates undesired lower extremity, pelvic, and trunk biomechanics through appropriating propulsion and bracing dynamics.
Book Synopsis Advancing Democracy by : Amilcar Shabazz
Download or read book Advancing Democracy written by Amilcar Shabazz and published by Univ of North Carolina Press. This book was released on 2005-11-16 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we approach the fiftieth anniversary of Brown v. Board of Education (1954), it is important to consider the historical struggles that led to this groundbreaking decision. Four years earlier in Texas, the Sweatt v. Painter decision allowed blacks access to the University of Texas's law school for the first time. Amilcar Shabazz shows that the development of black higher education in Texas--which has historically had one of the largest state college and university systems in the South--played a pivotal role in the challenge to Jim Crow education. Shabazz begins with the creation of the Texas University Movement in the 1880s to lobby for equal access to the full range of graduate and professional education through a first-class university for African Americans. He traces the philosophical, legal, and grassroots components of the later campaign to open all Texas colleges and universities to black students, showing the complex range of strategies and the diversity of ideology and methodology on the part of black activists and intellectuals working to promote educational equality. Shabazz credits the efforts of blacks who fought for change by demanding better resources for segregated black colleges in the years before Brown, showing how crucial groundwork for nationwide desegregation was laid in the state of Texas.

Taking a unique approach to the presentation of mechanical concepts, Biomechanics of Sport and Exercise eBook, Third Edition With Web Resource, introduces exercise and sport biomechanics in simple terms. By providing mechanics before functional anatomy, the book helps students understand forces and their effects before studying how body structures deal with forces. Students will learn to appreciate the consequences of external forces, how the body generates internal forces to maintain position, and how forces create movement in physical activities. Rather than presenting the principles as isolated and abstract, the text enables students to discover the principles of biomechanics for themselves through observation. By examining ordinary activities firsthand, students will develop meaningful explanations resulting in a deeper understanding of the underlying mechanical concepts. This practical approach combines striking visual elements with clear and concise language to encourage active learning and improved comprehension. This updated edition maintains the organization and features that made previous editions user friendly, such as a quick reference guide of frequently used equations printed on the inside cover and review questions at the end of each chapter to test students’ understanding of important concepts. The third edition also incorporates new features to facilitate learning: • Two online resources incorporate sample problems and use of video to allow practical application of the material. • New art and diagrams enhance problem sets and help students visualize the mechanics of real-world scenarios. • Increased number of review questions (200) and problem sets (120) provide an opportunity for practical application of concepts. • Greater emphasis on the basics, including improved descriptions of conversions and an expanded explanation of the assumption of point mass when modeling objects, provides a stronger foundation for understanding. • New content on deriving kinematic data from video or film and the use of accelerometers in monitoring physical activity keeps students informed of technological advances in the field. Biomechanics of Sport and Exercise eBook, Third Edition With Web Resource, is supplemented with two companion resources that will help students better comprehend the material. Packaged with this e-book, the web resource includes all of the problems from the book, separated by chapter, plus 18 sample problems that guide students step by step through the process of solving. This e-book may also be enhanced with access to MaxTRAQ Educational 2D software for Windows. MaxTRAQ Educational 2D software enables students to analyze and quantify real-world sport movements in video clips and upload their own video content for analysis. The software supplements the final section of the text that bridges the concepts of internal and external forces with the application of biomechanics; it also provides an overview of the technology used in conducting quantitative biomechanical analyses. The MaxTRAQ Educational 2D software must be purchased separately to supplement this e-book at the MaxTRAQ website. Instructors will benefit from an updated ancillary package. An instructor guide outlines each chapter and offers step-by-step solutions to the quantitative problems presented, as well as sample lecture topics, student activities, and teaching tips. A test package makes it easy to prepare quizzes and tests, and an image bank contains most of the figures and tables from the text for use in developing course presentations. Biomechanics of Sport and Exercise, Third Edition, is ideal for those needing a deeper understanding of biomechanics from a qualitative perspective. Thoroughly updated and expanded, this text makes the biomechanics of physical activity easy to understand and apply.
