This book was released on 2013 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rotational movements are considered an important component of hitting mechanics within the game of softball. Strength and conditioning coaches seek to improve the performance of softball players' bat velocity through various weighted implement training modes focusing on rotational movements. PURPOSE: The purpose of this study was to determine if an 8-week rotational medicine ball training protocol would increase bat velocity in a game like situation for prepubescent softball players. It was hypothesized that an 8-week rotational medicine ball training program would result in the greatest increase in bat velocity among prepubescent softball players. METHODS: Twenty-seven female prepubescent softball players (mean age = 10.2 + 1.2) participated in this study. Participants were randomly assigned to a medicine ball training (MB = 13) or control (CON = 14) group. Pre- and Post-testing consisted of warming up with 10 dry swings using the bat they normally use during competition followed by 10 hits off a pitching machine. Pitch speed was 30-40 mph depending on age. During the 8 weeks of training, the MB group completed a series of medicine ball throws that were aimed at developing rotational velocity. Exercises included side medicine ball throw for distance, side medicine ball throw for speed, partner russian twists, woodchoppers and standing side band rotations which were all done on both dominant and non-dominant sides. 8-10 year old participants used a 4-kg medicine ball while 11-13 year olds used a 6-kg medicine ball. 1 set of 12 repetitions was completed 2x/wk. RESULTS: A Repeated Measures ANOVA with a Randomized Cross-Over Design revealed no significant difference between conditions from pre- to post-testing (F=1.9, p=.18) and no significant difference over time in either group (F= .33, p= .57). Pre-test average velocity for CON = 36.1mph (+ 6.6) and MB = 36.8mph (+ 5.4). Post-test average velocity for CON =38.2mph (+ 8.6) and MB = 37.7mph (+ 4.4). CONCLUSION: Medicine ball training offers no additional benefits compared to normal in-season activities in prepubescent softball players. Mean velocity from pre- to post-testing did increase in both conditions, but not significantly. However, a more rigorous training program may prove to be more beneficial.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fast pitch softball is a popular and growing sport. High performance softball bats are hollow and often made from one or multiple shells of fiber reinforced composite materials. Composite bats can soften or break-in and increase their performance with use. There are three common break in methods: accelerated break-in for certification (rolling), natural break-in by hitting (hitting), and illegal rolling by bat doctors (bat doctoring). In 2005 illegal bat alteration resulted in a 4% increase in bat performance.This study has three aims: to analyze the effect of break-in treatment on bat damage; to characterize the life of hit bats and compare them to rolled bats; and to investigate the effect of current bat doctor treatments on the batted ball speed and bat barrel stiffness. Bats underwent three different treatments - rolling according to the certification standard, automated hitting in a laboratory setting, and bat doctoring by a third party. Ultrasonic inspection was used to non-destructively examine the damage in each composite bat. Bat performance changes were characterized by the batted ball speed and barrel compression measurements.Ultrasonic images showed different damage signatures for the three treatments. Rolling caused long delaminations down the length of the bat. Hitting caused localized impact damage in the form of ultrasonic attenuation. Bat doctoring did not cause observable damage. The batted ball speed and barrel compression were measured over the life of the bat. Comparing rolled and hit bats showed no statistically significant difference between the performance increases of these two treatments. Bat doctoring did not cause any performance increases. While rolling and hitting produced different structural damage, their similar performance showed that current bat altering methods are relatively benign.

This book was released on 2021 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purposes of this study were to determine the reliability of the bat swing (BS) and rotational medicine ball throw (RMBT) load-velocity profiling (LVP) methods and the relationships between LVP variables and batting performance in NCAA Division I softball players. Current NCAA Division I softball athletes participated in this study. Bat velocity was tracked with a swing sensor during the BS method. An inertial measurement unit (IMU) tracked forearm velocity during the BS and RMBT methods. Two-way intraclass correlation coefficients (ICC) were used for relative reliability and coefficient of variation (CV) was used for absolute reliability. For the BS method with the swing sensor, relationships between the multiple- and two-load models and between LVP variables and batting variables were examined using Pearson’s correlation coefficients. During the RMBT method and BS method using the IMU, no LVP variables were reliable (ICC [less than or equal to] 0.7; CV [greater than or equal to] 15%). For the BS method with the swing sensor, all bat loads and V0 had acceptable reliability using peak velocity (PV) and average peak velocity (PV[subscript avg]) (ICC > 0.7; CV

Download or read book An Experimental Comparison of Hitting Mechanics in Softball written by Victoria M. Jensen and published by . This book was released on 2016 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: To score points to win games, a softball team must be able to hit the ball with as the largest velocity as possible. In softball, there are two well-known hitting models, rotational and linear, yet little quantitative research has been done to determine which model produces the greatest ball velocity and if certain key inputs, such as weight shift and bat velocity, of the models contribute to that velocity. To determine these components, a high-speed EXLIM camera recorded the change in ball position to calculate the its exit velocity, a 70g accelerometer measured centripetal acceleration of the bat to determine bat velocity, while two force plates measured the transfer of weight as nine softball players swung a bat twenty times- ten times with a ball on the tee and ten times with a ball off of the tee. Although it was found that the two hitting models had statistically different weight shifts with 95% confidence, the average ball velocity for a linear model, 22.0 m/s ±1.9 m/s, was not different from the average ball velocity for a rotational model, 22.0 m/s ± 0.7 m/s, at 95% confidence. Since these values are not different with statistical significance, this research concludes that players that weight shift does not effect ball velocity and that players are encouraged to use whichever model feels most comfortable to them.

This book was released on 2015 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of Right View Pro© Video Analysis on bat speed and batted-ball exit velocity were evaluated in 29 male collegiate student-athletes. The 29 athletes were divided into three groups and evaluated on both dependent variables (bat speed and batted-ball exit velocity). Group A participated in weight training only, Group B participated in weight training and video analysis, and Group C participated in weight training, video analysis, and Right View Pro© video analysis. The Pocket Radar© was used to measure bat speed of each individual, while the Stalker Radar Sport 2 Radar Gun© was used to measure the speed of the batted-ball exit velocity. On the initial day of testing (September 3rd, 2013), participants completed their baseline bat speed and batted-ball exit velocity. After two semesters of the academic year (until May 6th, 2014), participants completed their post-test on bat speed and batted-ball exit velocity. A one way analysis of variance with post-hoc Tukey was used to analyze the data. The analysis of variance showed no significant difference between the three groups, p=0.18. The batted-ball exit velocity was significantly different (p=0.02), between Group A and Group B only. The Tukey post hoc criteria for significance indicated that a significant difference existed between Group A (Weight Training only) and Group B (Weight Training and Video Analysis), HSD (0.5) =5.44; HSD (.01) =6.97; and M1 vs. M2 P
Download or read book The Effects of Focused Attention on Batting Performance of Collegiate Athletes written by Lauren C. Craig and published by . This book was released on 2013 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Proper thinking is essential to effective batting in baseball and softball. However, the qualities that define "proper thinking" are unspecified and therefore require examination. That is, on what should a batter focus for optimal performance? Ten baseball players and 13 softball players competing at the NCAA Division II collegiate level were individually given internal and external focus instructions related to their swings and completed four rounds of hitting. Two experimenters blind to condition recorded the result of each swing; hits in fair territory received one point and hits in foul territory received zero points. Results indicated no significant difference between Focus Instruction administered and the mean number of fair hits. However, a significant interaction was found for class level, with upperclassmen (juniors and seniors) performing significantly better during both distal and proximal external conditions compared to lowerclassmen (freshmen and sophomores). Results also indicated a significant effect for sex with females outperforming males during all conditions. This study is important in discovering the impacts of focused attention instructions on the performance of collegiate level players."--Abstract.
Download or read book Effects of a Functional Fatigue Protocol on Maximal Softball Hitting written by Emilee M. Bounds and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue can affect athletic performance in many ways, including a decrease in sport specific accuracy, impairments in joint angles, and a decrease in overall muscle performance. In regards to fatigue, little research has been conducted examining the effects of fatigue on baseball and softball performance. The majority of the research stems from examining the effects of fatigue on the overhead throwing motion among collegiate baseball players. Research suggested that as a result of a functional fatigue protocol, baseball pitchers experienced impairments in joint angles in the overhead throwing motion. Among this same population, throwing velocities decreased significantly from the first to last inning pitched, resulting in a great deal of in-game fatigue. Researchers attested that such changes in angles and velocities as a result of fatigue, would negatively affect performance. The purpose of this study was to examine the effects of a functional fatigue protocol on softball hitting form. Additional research, examined the effects of fatigue on performance among skilled tennis athletes. A functional fatigue protocol was implemented, which directly simulated tennis matchplay. Results revealed decreases in tennis hitting accuracy, and just as with the baseball players, fatigue resulted in a decrease in performance. A secondary objective was to identify the relationship between hitting variables, muscular power, and body composition. Participants (n = 6) were NCAA Division II softball players with a mean age of 19.5 ± 1.4 years who completed a functional fatigue protocol (FFP). The FFP was filmed using a digital video camera, and results were analyzed using Dartfish motion analysis software. To address the secondary objectives, participants completed the Wingate Anaerobic Power test to assess muscular power and a dual-energy x-ray absorptiometry (DXA) scan to discover body composition values. To detect differences in swing angles pre- and post-fatigue, an ANOVA was conducted revealing significant (p .05) decreases in linear bat-end velocity (LBEV; F = 12.479, p = .017) and batted-ball velocity (BBV; F = 11.856, p = .018) as a result of fatigue. A Pearson's product moment correlation coefficient performed to examine relationships between hitting variables, muscular power, and body composition. Results revealed no significant relationships (p .05) between muscular power and LBEV or BBV, in addition to no significant relationships between percent fatigue as measured by WAnT or the FFP. Meaningful relationships were discovered between peak power and LBEV and BBV. A strong, negative correlation was present between peak power and BBV (r = -.73, p = .097) and a moderate, negative correlation between peak power and LBEV ( r = -.68, p = .138). Additionally, percent body fat was negatively related to percent fatigue in LBEV(r = -.76, p = .082). Results indicated that fatigue did in fact have a negative effect on softball hitting form, with significant decreases in LBEV and BBV, and that peak power and hitting velocities were inversely related. Although no differences were found in swing angles at ball contact, changes in LBEV and BBV could be detrimental to swing timing and performance. Results of this study will be utilized to further understand the effects of fatigue on softball hitting form and the role of muscular power and body composition on hitting performance.
