This book was released on 2001 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throwing is a complex biomechanical feat that requires a balance between mobility and stability of the human kinetic chain. Shoulder muscle weakness and adaptive tissue changes have been proposed as a possible risk for developing injury. Objective quantification of anthropometric characteristics has been identified in a population of professional baseball pitchers, but there is a paucity in the literature regarding the adolescent pitcher. The purpose of this study was to identify characteristics of healthy adolescent pitchers and determine the relationships between shoulder passive range of motion, eccentric strength, field-testing performance and other anthropometric data to pitching velocity. Thirty-seven healthy Babe Ruth baseball players age 14-15 were tested bilaterally for selected anthropometric and field testing measurements to determine if the throwing side differed in strength, range of motion, and various performance measures from the nonthrowing side. Passive internal and external range of motion was bilaterally measured at 90° of abduction. Muscle strength of the supraspinatus, handgrip, and internal and external glenohumeral rotators were measured with a hand-held dynamometer. Field-testing consisted of the following tests: sit-ups, medicine ball throw, standing long jump, and Davies Closed Kinetic Chain Upper Extremity Stability Test. Correlational statistics were used to determine if any of these characteristics were significant predictors for pitch velocity in adolescent pitchers. No significant strength difference existed between extremities in external rotator, internal rotator, or supraspinatus strength. However, a significant difference of handgrip strength existed in the pitching arm as compared to the nonpitching arm. When compared to the nonpitching arm, the bilateral glenohumeral passive range of motion tests demonstrated greater passive external rotation in 90° of abduction in the pitching arm of adolescent players. Results demonstrated significantly greater distance by the nonpitching side during the single-leg hop test. Furthermore, this study identified external rotation strength and the single-leg hop test (stride leg) distance as two significant predictors for pitch velocity in adolescent pitchers. The strength, range of motion, and performance characteristics identified in this study can assist the practitioner in evaluating and treating adolescent athletes who use overhead throwing motions.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Due to the repetitive, high forces and torques placed on an individual during a baseball pitch, shoulder pain is present in 46-57% of pitchers. Therapeutic taping has been used in various sports including baseball as it has been proposed to have beneficial qualities in injury prevention and rehabilitation and performance enhancement via muscular facilitation. Therefore, the purpose of this study will be to investigate the effect of taping (Kinesio Tape® and no tape) on the velocity of an overhead baseball throw and muscle activation patterning of the supraspinatus, infraspinatus, teres minor, and pectoralis major muscles in baseball players after muscle fatigue has been induced. Methods: Participants were asked to complete two, 45-minute sessions under two different taping conditions (no tape and Kinesio Tape®). Participants were asked to complete three pretest maximum velocity overhead throws, a fatiguing protocol, followed by three post-test maximum velocity pitches while velocity and EMG activity in the infraspinatus, supraspinatus, teres minor, and pectoralis major muscles were measured. Results: There was no statistically significant difference in throwing velocity with the application of the different taping conditions, t(5)=.456, p=.668. There was no statistically significant difference in tape conditions on the supraspinatus muscle activity in phases one (t(6)=-1.023, p=.346) , two (t(6)=.172, p=.869), or three (t(6)=-.299, p=.775) of the overhead throw. There was no statistically significant difference in tape conditions on the infraspinatus muscle activity in phases one (t(6)=.436, p=.678), two (t(5)=1.66, p=.158), or three (t(5)=.314, p=.766) of the overhead throw. There was no statistically significant difference in taping conditions on the pectoralis major muscle activity in phases one (t(5)=.871, p=.424), two (t(4)=.520, p=.63), or three (t(5)=1.073, p=.332) of the overhead baseball throw. Conclusion: Based on the results of this study, Kinesio Tape® does not significantly change muscle activation or velocity of an overhead baseball throw when compared to a no tape condition. Future research needs to complete testing with a larger sample size to better capture the effects of taping on surface EMG in the baseball population. Clinicians, baseball players, baseball coaches, and trainers should consider the possible pros and cons of taping in deciding whether or not to apply therapeutic taping to the shoulder and the rotator cuff muscles.

This book was released on 2018 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Research investigating baseball position players has been limited primarily to pitchers. The current study examined several kinematic variables and their relationship with ball velocity in middle and high school-aged baseball players using two-dimensional (2D) motion analysis. The purpose of this study was to investigate these relationships using 2D motion analysis and compare these results to those reported in the literature using 3D analysis. Thirteen baseball players (15.31 ± 1.25 yrs., 72.29 ± 10.79 kg and 177.09 ± 5.59 cm tall) participated in the study. A video camera was used to record three throwing trials for each participant. Four reflective markers were placed on the participants to identify anatomical landmarks of interest on the players. Video trials were digitized in 2D using commercially available Dartfish software. Trunk side bend and knee flexion angle at foot contact, and trunk flexion, knee flexion, and knee extension velocity at ball release were calculated. Intra-rater reliability of ten re-digitized trials using Pearson's inter-item correlation was very high (r = 0.99, p

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Baseball specific athleticism, potential and performance have been difficult to predict. Muscle strength and power has shown to help increase throwing velocity through resistance training research however themajority of research has focused on the upper body. The present study sought to determine if bilateral or unilateral lower body field testing correlates with throwing velocity and if so to what extent. Throwing velocity scores were correlated to the following tests; medicine ball scoop toss and squat throw, bilateral and unilateral vertical jumps, single and triple broad jumps, hop and stop in both directions, lateral to medial jumps, 10 and 60 yard dash, and both left and right single leg 10 yard hop for speed in 42 college baseball players. It was hypothesized that the concentric strength of the trail leg and the eccentric strength of thelead leg will correlate positively with throwing velocity. A stepwise multiple regression analysis, assessing therelationship between shuffle and stretch throwing velocities and lower body field test results determined that right handed throwing velocity from the stretch position was significantly predicted by lateral to medial jump right (LMJR) and body weight (BW) R2 =0.322, whereas lateral to medial jump left (LMJL) R2 = 0.688 significantly predicted left stretch throw. Right handed shuffle throw was significantly related to LMLR and Medicine Ball scoop R2 =0.338; whereas, LMJL, BW and LMJR significantly contributed to left handed shuffle throw R2=0.950. Overall, this study found that lateral to medial jumps were consistently correlated with highthrowing velocity in each of the throwing techniques, in both left and right handed throwers. This is relevant because it is the first study to our knowledge to correlate throwing velocity with a unilateral jump in thefrontal plane, mimicking the action of the throwing stride.
