Relationship Between Kinetics of Countermovement Jump and Proximal Mechanics of Collegiate Baseball Pitching
Louisiana Tech University Louisiana Tech Digital Commons Master's Theses Graduate School Spring 5-2021 Relationship between Kinetics of Countermovement Jump and Proximal Mechanics of Collegiate Baseball Pitching Motoki Sakurai Follow this and additional works at: https://digitalcommons.latech.edu/theses Part of the Kinesiology Commons RELATIONSHIP BETWEEN KINETICS OF COUNTERMOVEMENT JUMP AND PROXIMAL MECHANICS OF COLLEGIATE BASEBALL PITCHING by Motoki Sakurai, B.S. A Thesis Presented in Parital Fulfillment Of the Requirements for the Degree Master of Science in Kinesiology COLLEGE OF EDUCATION LOUISIANA TECH UNIVERSITY May 2021 ABSTRACT Purpose: To identify how countermovement jump (CMJ) kinetics influence kinematics and momentum of the baseball pitching motion with a focus on lower body and proximal movement. Methods: Nineteen Division I collegiate pitchers (age = 19.9 ± 1.5 years; height = 1.86 ± 0.06 m; weight = 90.7 ± 13.8 kg) performed a bilateral CMJ test and threw 5 strike fastballs from the stretch with a slide step on a custom-made pitching mound built for a laboratory setting. A 3D motion capture system tracked whole-body kinematics at 240 Hz from 29 reflective markers. Two force plates recorded ground reaction forces (GRFs) from each leg at 1040 Hz during both jump test and pitching captures. A one-way ANOVA separating high and low fastball velocity groups by an athlete’s median performance identified differences in pitching mechanics and jump kinetic variables. Meaningful differences between the variables were determined by cohen’s d effect size with 95% confidence intervals. The same statistical calculations were repeated to identify differences in pitching mechanics and jump kinetic variables between two groups, split based on the medians of pitchers’ total linear momentum in anterior-posterior direction. -

PLAY BALL! MAJOR LEAGUE BASEBALL in BLOOMSBURG Did
PLAY BALL! MAJOR LEAGUE BASEBALL IN BLOOMSBURG Did you ever dream of seeing major league baseball in Columbia County? It happened once in the past. During the recent American League Divisional Championship series between the New York Yankees and the Detroit Tigers, a few Columbia County long-time baseball fans were reminded of the series played between those same two teams at the Bloomsburg Fair in October 1925. The two major-league teams were scheduled for a three-game series during Fair week. They played on an improvised field on the racetrack infield in front of the grandstand. Each squad brought to town only the bare minimum of players; the Yankee pitchers when they were not on the mound played in the outfield. Two games were completed; the third day’s game was rained out and couldn’t be rescheduled because the teams left town for an engagement in Wilkes-Barre. The Tigers won both games, but both were close, exciting contests. The games were slated at 10:00am each day so as not to conflict with the trotting races held in the afternoons. Apparently, the Fair Board was hoping that the major leaguers would draw folks to the Fair in the usually-slack morning hours. And the scheme worked – the games drew upwards of 10,000 fans each day. At the time, the grandstand capacity was only 2,000, so the other fans crowded the railing around the oval track. In 1925 the Yankees were in the middle of their storied 1920s championship era. With Babe Ruth and Lou Gehrig as mainstays, this was arguably the greatest baseball team ever assembled. -

Hillsborough claims District 52 9-10s title behind pitching gem | Sports | smdailyjournal.com 7/5/17, 4(00 PM FEATURED Hillsborough claims District 52 9-10s title behind pitching gem By Terry Bernal Daily Journal Staff Jul 5, 2017 Updated 1 hr ago It’s an old baseball adage — if a pitcher throws a shutout and “He had the fastest arm we’ve seen, so he was throwing heat,” hits a home run, it’s a guaranteed win. The same can be said of San Mateo National manager Dan Luzzi said. “And that a near-perfect shutout gem combined with going 4 for 4 at the curveball was working for him. He was just great.” plate with three runs scored. And the efficiency was something not often seen from a 10- That’s precisely what Hillsborough 10-year-old Anakin Manuel year-old pitcher. While three different National pitchers did Tuesday night in the District 52 Little League 9-10s All-Star combined to issue four walks and a hit batsman — fairly Tournament championship game. Not only did Manuel notch a perfect 4-for-4 performance at the plate, he came within one routine totals for the 9-10s bracket — Manuel allowed nothing hit of perfection on the mound, facing one batter over the wild. minimum to fire a one-hit shutout to lead Hillsborough to the District 52 crown at Ford Field with a 9-0 win over San Mateo Not only that. Of the 19 batters he faced, he started 17 of them National. with first-pitch strikes. -

House-Ch-5-Flext Elbow Position at Release.Pdf
No one pitch, thrown properly, puts any more stress on the arm than any other pitch." Alan Blitzblau, Biomechanist The Pitching Edge crxratt....-rter hen I first heard Alan Blitzblau's remark on the previous page, 1 was more than a little skeptical. He had to be wrong. For many W years, I, like everyone else, had been telling parents of Little Leagu- ers that their youngsters should not throw curveballs, that curveballs were bad for a young arm. "Now wait a minute," I said, "you've just dis- counted what's been taught to young pitchers all over the United States. Are you sure?" "I'm sure," he responded. Alan sat down in front of the computer and showed me what he had discovered. From foot to throw- ing elbow, every pitch has exactly the same neuromuscular sequencing. The only body segments that change when a different type of pitch is thrown are the forearm, wrist, hand, and fingers, and they change only in angle. Arm speed is the same, the arm's external rotation into launch is the same, and pronation during deceleration is the same. It is the differ- ent angles of the forearm, wrist, hand, and fingers that alter velocity, rota- tion, and flight of a ball. He also revealed another surprise. The grip of a pitch is secondary to this angle, and all pitches leave the middle finger last! This was blasphemy I was stunned. But Alan wasn't finished. "Tom, for every one-eighth inch the middle finger misses the release point when the arm snaps straight at launch, it (the ball) is eight inches off location at home plate So throwing strikes means getting the middle finger to a quarter-sized spot on the middle of the baseball with every pitch." Wow! This chapter will dispel myths about what happens to pitcher's elbows, forearms, wrists, and fingers at release point, For years, pitching coaches (me included) taught pitchers to "pull" their glove-side elbow to their hip when throwing. -
