This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The sport of softball has gained increasing popularity over the last few decades with young girls competing at many levels in hopes of advancing to collegiate or Olympic competition. The Amateur Softball Association currently has 83,000 teams comprising 1.2 million participants. While many comparisons between baseball and softball have been made, pitch delivery stands out as an obvious difference. Softball pitchers deliver the ball in an underhand motion from a flat mound at a distance of 43 feet. Currently, there are no rules governing the number of pitches a pitcher can throw or the practice of pitching in consecutive games. Current research on the windmill softball pitching motion provides information on only one type of pitch; the fastball. The objectives of this study were to provide kinematic descriptions and kinetic comparisons of the upper extremity for three different types of softball pitches (fastball, changeup, and drop). It was hypothesized that there would be no differences in the kinetic values between pitches. Eleven high school aged softball pitchers (age= 15.4 " 1.2 yr.; ht= 159.2 " 10.8 cm; mass= 55.9 " 8.4 kg) were recruited for this study and had to be able to throw fastball, changeup, and drop pitches with proficiency. Motion analysis was used to collect five trials of each type of pitch. Kinematic description included a 4-curve approach for the shoulder motion, while the elbow and wrist motions involved standard Euler calculations. Statistical analysis of the kinetic variables included a one-way analysis of variance (ANOVA) and Tukey post-hoc techniques in order to compare peak moment, peak joint reaction force, and peak joint power values (shoulder, elbow, and wrist joints) between the pitches. Descriptive kinematics established normative data for each of the three pitches using a unique shoulder model. Shoulder, elbow, and wrist compression joint reaction forces were significantly different between pitches with the fastball/changeup and drop/changeup combinations. No significant differences were found for joint moments. Joint powers were significantly different for shoulder horizontal flexion/extension powers. Data from this study can be used to establish normative kinetic and kinematic information for different types of softball pitches in high school softball pitchers. Although the arm is not placed in an abducted position as with baseball pitching, dynamic and static restraint structures are still responsible during the delivery phase for stabilizing against distraction loads at all three joints. These structures include the long head of the biceps tendon and the rotator cuff musculature (shoulder); the ulnar and radial collateral ligaments and the distal tendon of the biceps brachii (elbow); and the ulnar and radial collateral ligaments (wrist). Future study will involve a lower extremity biomechanical analysis and injury prevention interventions.

This book was released on 1978 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine the relative velocities of the three segments of the upper extremity during a highly skilled ballistic movement. The skill chosen for analysis was the windmill pitch in the game of softball. Four highly skilled softball pitchers, two female and two male, were the subjects in the study. Of the ten pitches performed by each of the subjects during the testing session, the two pitches of each subject with the highest velocity were chosen for detailed analysis. The subjects were filmed by two cameras, one placed to the side at right angles to the direction of the pitch, and the other one placed to the rear of the subject. The subjects also pitched from a force platform, so that the reaction of the pitcher on the ground could be recorded. The records from the two cameras and the force platform were synchronized by means of an electric timer, such that the speed of the timing flashes was altered at a point in the pitch. Other problems investigated in this study included the determination of the coordinates of the segmental endpoints of the pitching arm in three-space, and the comparison of these with the values obtained from the planar analysis. Also, a method was devised to calculate the magnitudes of the angular velocities of the lower arm segment which could be utilized to determine these parameters for any of the other body segments. In particular, the angular velocities of particular interest were those occurring around the longitudinal axis of the segment, which were believed to be of importance in this skill. Computer programs were written to calculate the kinematic and kinetic parameters of the segments of the upper extremity during this skill from the digitized film data. The spatial coordinates of the segmental endpoints were determined by use of an available computer program, and the X,Y, and Z velocity components of each of these points were determined and graphed. The pitching arm was analyzed further during the frames surrounding release of the ball to determine the magnitudes of the angular velocities around the three principal axes of the lower arm segment. The following are the main results of the study: (1) the force platform and the calculated forces from the mass center accelerations produce similar X and Y force records, (2) there is a definite sequence of segment motions which characterizes the highly skilled performers analyzed in this activity, (3) the largest, most proximal arm segment reaches maximum velocity at the earliest point in the skill, followed by the peak velocities of the distal segments, (4) the proximal segment also attains peak acceleration earliest in the skill, followed by the peak accelerations of the other two segments, (5) the directions of the force and acceleration vectors are almost 90 degrees different from those of the velocity and displacement vectors for these segments (6) the most forceful muscle action occurring in this skill is that produced by the shoulder extensors in decelerating this segment prior to release of the ball (7) the three dimensional coordinates produced from the film in this study are fairly accurate (+ or - 7%) estimates of these points, (8) the Z-component of the velocity of the arm segmental endpoints is relatively small (approximately twenty per cent of the X and Y values) r and probably relatively unimportant in this skill (9) the peak value for the angular velocity of the pronation movement of this skill occurs at the same instant as the peak velocity for the elbow flexion movement.

Book excerpt: Sport, Fun and Enjoyment explores the pleasurable aspects of sport within the context of everyday recreational and competitive physical activities. While much recent work has focused on the relationships between physical activity, health and wellbeing, much less attention has been paid to pleasure and fun, key aspects of our engagement with sport but not so easy to measure in terms of specific outcomes. By offering a critical exploration of what can be constituted as ‘fun’ in a sporting context, this book reveals the complex ways in which individuals approach sport and engage with it throughout the life course. The book considers the importance of pleasure and fun as a factor in our initial, formative experiences of sport activity, and as a factor in participation and continued participation. It explores the nature of fun as an embodied experience which incorporates a multitude of social, psychological and physiological components, and as a subjective experience which cannot be fully explained through simplistic binary formulations of pleasure and pain. Drawing on a wide research literature and original empirical research with children and adults, the book outlines a new theoretical framework for thinking about pleasure and fun in sport, highlighting the contrasting ways in which sport and physical activity is experienced and the interplay between individual and social contexts. Sport, Fun and Enjoyment is important reading for anybody with an interest in physical education, youth sport, the sociology of sport, physical activity and health, sport development or sport policy.
