(July): 21. Submitted by: Richard C. Bell, Ed.D., J.D. Figure 3 displays data of BQ vs. BV with the top and bottom 10th percentiles removed from the data set. This is why the beginning stage is crucial to the overall performance High-speed video cameras recording at 300 Hz were located along the first and third base lines recording every pitch. pitcher is the key player on all softball teams, and the strength of the team Noble, L., and Eck, X. Air affects the flight of flyin, g around the ball from front to back. Sport Biomechanics Laboratory Faculty of Kinesiology and Recreation Management University of Manitoba . This variety in talent may explain why the best velocities in BV were associated with the smallest swing times in BQ (likely better players on better teams) and vice versa (worse players on worse teams). The teams in this study were ranked at the following RPI: 1, 59, 71, 73, 161, and 217. These were swings probably executed by stronger, higher level players, and future research should examine the strength training implications for these kinematic variables in executing a swing. The bat head was also digitized four frames prior to the frame of contact. Stellar, T., House, T., DeRenne, C., & Blitzblau, A. BQ and BV correlations produced coefficients that ranged from 0.379 – 0.975. They were noncompetitive, informal, rule-less; they emphasized physical activity rather than competition. "Biomechanics of Youth Windmill Softball Pitching." The information in this blog can therefore be useful in injury prevention as the use of good pitching technique can help prevent injuries. The ideal moment of inertia for a baseball or softball bat. To guide the athlete, the coach or teacher should first teach the athlete to "push off" with their back leg then thrust their guiding leg out as far as they can. The mound is Blazevich (2010) elaborates on the mechanics of a throw-like pattern. The FIRST thing to adjust in a player's swing when they are slumping and having trouble controlling the bat (this small grip adjustment has helped many UCLA softball players get back on track in no time), Have a player with perfect mechanics who can't convert that into solid hits? wind up phase of the softball pitch, a crucial technical element is the The mean BA for all swings was 144.30 m/s2 (± 38.44 m/s2). the shoulder in the throwing athlete. Softball pitching is the most important skill in the game of softball, as the pitcher ... arm swing with the elbow flexed … Video was converted to the AVI format for use in Maxtraq (Innovision Systems, Inc., Columbiaville, MI) software for digitizing. For a lateral view of a right handed pitcher please see figure one. Pitchers like these have pitches such as a Air from the top of the ball is flowing in the same direction that the Baseball vs. Softball Swing Reaction Time. The way in which the weight is distributed for a softball bat compared to a baseball bat leads to a softball bat feeling easier to swing compared to the bats used by MLB (8). Because of the nature of the game, softball is generally quite low scoring, with some teams only managing to score one or two runs for the duration of the game and this is often due to the ability and skill of the pitcher. Future studies should take a look at the predictive power of these swing kinematic variables on in game statistical performance variables. Retrieved from http://www.rightviewpro.com/about-us/founders-     staff/candrea. Conversely, a quicker swing that was completed in less time (lower BQ), would have a slower BV (9). No questions asked. Alexander, This article takes a point/counterpoint approach to the topic of paying athletes and may have potential implications/consequences for college administrators, athletes, and coaches. The mean BQ for all swings was 0.21 s (± 0.042 s). information of the principles will allow coaches and teachers to educate learners on how to execute the skill of pitching successfully. Get Assignment help from the expert. As hypothesized, the relationship between BV and BQ became positive within a stratus of similar swings. In the late 1800's and early 1900's, women began to form clubs that were athletic in nature. is an exciting and dynamic skill that requires many years of practice to The participants in this study were between the ages of 18 and 23 years old. Hay (1973) also touches on the significance the follow through being performed correctly so as to not impair the application of forces to the ball and to enable the pitcher to move into a position where they are ready to field as quickly and efficiently as possible. Australian Sports The purpose of this study was to describe basic kinematic variables of the swing and the relationships that exist between these variables in Division I female softball players. Figure 1. Descriptive statistics (mean ± SD) were calculated for all swing kinematic variables. Despite the physiological differences that exist, there can be several reasons to explain why there are similarities. Games www.steadman-hawkins.com. All swings were rank ordered by BA and assessed for relationships among BV, BQ, and BA. To calculate BV, the horizontal displacement of the bat head between contact and five frames prior to contact was converted to meters and divided by 1/75s, which is the time spanned by four frames. Ficklin T.K., and Lund R. (2014). Pearson product moment correlations were used to determine the strength of the relationships in question. Guided by biomechanics this blog will demonstrate how to pitch a softball consistently accurately and with good speed in order to trouble the opposing batter. To mark the onset of the swing, the head of the bat was digitized in the frame at which the swing started. A coaching cue that can be given to the pitcher is to only flex the wrist once the pitcher’s inner forearm brushes the hip of the pitching arm side. as a generator for the start of the momentum and the beginning of the pitching of the pitch, as the force generated and momentum transition increases the You love the plans or you don’t pay for them. effectiveness and will aid in injury prevention as previously discussed. BV vs.   BQ Relationships for Swings in 10th-90th Percentile, Figure 4. (1993). Recreation Management. There is not a lot of time to decide and The mean BV for all players was 29.12 m/s (± 2.19 m/s). Instead, a significant inverse correlation was observed between BV and BQ. Werner, S. L., T. A. Murray, opposite direction because of the friction with the balls surface. Biomechanical Analysis of Softball Pitching Technique. The Biomechanics of Sports Dennis A. Johnson, Ed.D., John Acquaviva, Ph.D. on Swing Kinematics Described in Division I Female Softball Players, Exposure to Women’s Sports: Changing Attitudes Toward Female Athletes, A History of Women in Sport Prior to Title IX, Point/Counterpoint: Paying College Athletes, The R.I.C.E Protocol is a MYTH: A Review and Recommendations, Assessment of readiness of Lebanese Gyms and Sport Facilities according to ISO-97.220 – Sports equipment and facilities, Pay to Play in the NCAA: A Data Driven Playbook on How to Compensate Athletes. pitch". Bat quickness and BV correlations for each strata can be found in Table 5. body segments further from beginning of the movement], much like the transfer that occurs in a fishing rod". In an attempt to group like swings with one another, all swings were sorted by BA and placed into ten strata of similar size based on percentiles. Then, the bat head was digitized at contact or, in the case of a miss, in the frame at which it had attained the same horizontal position as the ball. Pearson product moment correlations were used to examine relationships among the swing kinematic variables. Total reaction time given to hitters (the time between the release of the ball by the pitcher to the instant at which contact needs to be made) is comparable between elite-level baseball and softball hitters. In conclusion, the swing kinematic variables described in this study clearly show that similarities exist between Division I softball hitters and MLB baseball hitters. Additionally, a study found a direct relationship between the speed of the ‘sweet-spot’ (the point of the bat that is most advantageous to make contact with the ball) and the speed of the bat center of mass. World Congress on Biomechanics. Once the technique is completed, the body will have fully rotated, with the closing of the hips and shoulders in rotation so they are facing the initial direction of the pitching sequence, with weight landing on the striding leg. Sydney, Australian Sports Commission. (2003). Empirical determination of the axis of percussion of softball and baseball bats. Commission (1998). 43 feet away from home plate which is 13.1 metres of displacement, this means It required American society to recognize a woman's right to participate in sports on a plane equal to that of men. The simple truth about "rotational" vs "linear" hitting mechanics. (1985). ball is moving, while air from the bottom of the ball is being dragged in the the batter has 0.43 seconds until the ball meets the catcher’s glove. The descriptive statistics of the swing kinematic variables collapsed for all players can be found in Table 2. Because of the reduced mass and moment of inertia of the softball bats, it is reasonable to witness similar BV values generated during the BQ times of swing. Vol.16(10), pp.2056-2065, Hasselbach, T. (2014) "MOVESCI 330: "Biomechanics of a softball However, the strength of these relationships within some of the strata was unexpected. Typically, those with longer stride lengths exhibit greater vertical forces and overall ball velocity than those with shorter stride lengths (Olivera and Plummer 2011). Additionally though biomechanical. The drills helped my team in the field and the practice plans kept me on track. Alpha was set at p<0.05 for all tests. Bat velocity is measured in m/s and is measured at the instant the bat makes contact with the ball. Digitizing and calculations were executed using a method that has been shown to yield valid velocity data for swings recorded from the camera orientation used (4). Greater BA values come from some combination of maximizing BV and minimizing BQ. Cassie Reilly-Boccia is a former member of the National Champion University of Alabama softball team and is the Director of Research and Development at Athletes Warehouse in Pleasantville, NY.
