Sabermetrics is the original or blanket term for sports analytics in the US, the empirical analysis of baseball, especially the development of advanced metrics based on baseball statistics that measure in-game activity. The term is derived from the movement's progenitors, members of the Society for American Baseball Research (SABR), founded in 1971, and was coined by Bill James, who is one of its pioneers and considered its most prominent advocate and public face.
Ulnar collateral ligament reconstruction, colloquially known as Tommy John surgery, is a surgical graft procedure where the ulnar collateral ligament in the medial elbow is replaced with either a tendon from elsewhere in the patient's body, or with one from a deceased donor. The procedure is common among collegiate and professional athletes in several sports, particularly in baseball. The surgery is performed to restore optimal function for repetitive elbow movements or specifically throwing ability, often extending the careers of professional athletes. In many athletes, the surgery is done more than once during their careers.
In baseball, the pitcher is the player who throws ("pitches") the baseball from the pitcher's mound toward the catcher to begin each play, with the goal of retiring a batter, who attempts to either make contact with the pitched ball or draw a walk. In the numbering system used to record defensive plays, the pitcher is assigned the number 1. The pitcher is often considered the most important player on the defensive side of the game, and as such is situated at the right end of the defensive spectrum. There are many different types of pitchers, such as the starting pitcher, relief pitcher, middle reliever, lefty specialist, setup man, and the closer.
Motion capture is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robots. In films, television shows and video games, motion capture refers to recording actions of human actors and using that information to animate digital character models in 2D or 3D computer animation. When it includes face and fingers or captures subtle expressions, it is often referred to as performance capture. In many fields, motion capture is sometimes called motion tracking, but in filmmaking and games, motion tracking usually refers more to match moving.
In baseball, the pitch is the act of throwing the baseball toward home plate to start a play. The term comes from the Knickerbocker Rules. Originally, the ball had to be thrown underhand, much like "pitching in horseshoes". Overhand pitching was not allowed in baseball until 1884.
In baseball, batting is the act of facing the opposing pitcher and trying to produce offense for one's team. A batter or hitter is a person whose turn it is to face the pitcher. The three main goals of batters are to become a baserunner, to drive runners home or to advance runners along the bases for others to drive home, but the techniques and strategies they use to do so vary. Hitting uses a motion which is virtually unique to baseball and its fellow bat-and-ball sports, one that is rarely used in other sports. Hitting is unique because it involves rotating in the horizontal plane of movement, unlike most sports movements which occur in the vertical plane.
In baseball, there are two legal pitching positions: the windup, and the set. Colloquially, the set is often referred to as "the stretch", although this term actually only refers to one part of the pitching motion when pitching from the set.
Erick Harding "Rick" Peterson is an American former pitcher and pitching coach in Major League Baseball. He was most recently the director of pitching development for the Baltimore Orioles. He was a pitcher in the Pittsburgh Pirates organization, but is most notable as the pitching coach for the Oakland Athletics, New York Mets, and the Milwaukee Brewers.
Video motion analysis is a technique used to get information about moving objects from video. Examples of this include gait analysis, sport replays, speed and acceleration calculations and, in the case of team or individual sports, task performance analysis. The motion analysis technique usually involves a high-speed camera and a computer that has software allowing frame-by-frame playback of the video.
The following is a chronological list of the technological advancements of Major League Baseball television broadcasts:
Motion analysis is used in computer vision, image processing, high-speed photography and machine vision that studies methods and applications in which two or more consecutive images from an image sequences, e.g., produced by a video camera or high-speed camera, are processed to produce information based on the apparent motion in the images. In some applications, the camera is fixed relative to the scene and objects are moving around in the scene, in some applications the scene is more or less fixed and the camera is moving, and in some cases both the camera and the scene are moving.
Little League elbow, technically termed medial epicondyle apophysitis, is a condition that is caused by repetitive overhand throwing motions in children. "Little Leaguer's elbow" was coined by Brogdon and Crow in an eponymous 1960 article in the American Journal of Radiology.
James Andrews is retired American orthopedic surgeon. He is a surgeon for knee, elbow, and shoulder injuries and is a specialist in repairing damaged ligaments. Practicing in Gulf Breeze, Florida, Andrews has become one of the best-known and most popular orthopedic surgeons and has performed on many high-profile athletes. He also is the team doctor for the Tampa Bay Rays, Auburn Tigers, and Washington Commanders.
Sports biomechanics is the quantitative based study and analysis of athletes and sports activities in general. It can simply be described as the physics of sports. Within this specialized field of biomechanics, the laws of mechanics are applied in order to gain a greater understanding of athletic performance through mathematical modeling, computer simulation and measurement. Biomechanics, as a broader discipline, is the study of the structure and function of biological systems by means of the methods of mechanics.
The overhandthrow is a single-handed throw of a projectile where the object is thrown above the shoulder.
Ulnar collateral ligament injuries can occur during certain activities such as overhead baseball pitching. Acute or chronic disruption of the ulnar collateral ligament result in medial elbow pain, valgus instability, and impaired throwing performance. There are both non-surgical and surgical treatment options.
In baseball, hitting mechanics studies the biomechanical motion that governs the swing of a baseball player. The goal of biomechanics in hitting during baseball training is to study and improve upon the physics involved in hitting. This includes optimizing a player's swing for either maximizing their "bat speed" or time for plate coverage. There is a wide range of batting stances and mechanics that are developed through individual preferences. However, when comparing among experienced baseball players, their batting mechanics approach are almost similar.
Gideon Ariel is an Israeli authority in biomechanics, as well as a former Olympic track and field athlete who competed in the discus throw.
Kyle Boddy is an American baseball pitching trainer and consultant. He is the founder and owner of the baseball performance training system Driveline Baseball, which uses a sabermetric approach to increase pitching velocity and improve conditioning.
The TrackMan is a radar system that uses Doppler technology to track and record 3D characteristics of a sports ball in motion.
