Sir Isaac Newton, Baseball Coach

<p>(<a href=NewsUSA) – Many baseball coaches and trainers believe that one of the keys to good performance and career longevity for pitchers is proper form and mechanics. Coaches go to great lengths to teach pitchers, even those in Little League, the correct rotation of the hips during delivery, the proper release point of the pitch and other nuances, as well as to point out the mechanical flaws that a player might display when throwing a baseball.

Instructional approaches vary from coach to coach and team to team. Mike Marshall, the former major league baseball hurler, teaches an interesting pitching methodology. It is based on Sir Isaac Newton’s three laws of motion.

Marshall, who played in the major leagues for 14 years and won baseball’s most prestigious pitching honor, the Cy Young Award, in 1974, believes “pitchers of all ages would be very well served by learning and applying the three laws of motion correctly,” he says in Mechanical Engineering magazine.

Proper biomechanics based on Newton’s law of inertia, law of acceleration, and law of reaction, says Marshall, could solve basic flaws in pitching delivery and promote physical health and career longevity. Marshall, the recipient of a Ph.D. in exercise physiology from Michigan State University in 1974, believes that traditional pitching methodologies advanced by baseball coaches at all levels contradict the laws of physics.

Marshall applies Newtonian principles to every aspect of a baseball pitcher’s windup, arm and leg movement, delivery and follow-through. Mastery of the three laws, says Marshall, could erase flaws in leg thrust, rotation of the body, release point of the baseball toward home plate and position of the shoulders, forearm and elbow of the throwing arm.

Marshall’s approach is to reduce “the unnecessary force that bones, ligaments, tendons and muscles must overcome” when a pitcher throws a baseball, according to Mechanical Engineering, the flagship publication of the American Society of Mechanical Engineers (ASME). The report concludes: “According to Marshall, the traditional pitching techniques are almost always taught with a minimal understanding of the underlying biomechanics — this practice must be replaced with the vastly increased knowledge and understanding we have acquired through medical science.”

ASME, through the organization’s Bioengineering Division and other programs and activities, explores the application of mechanical engineering knowledge and principles to the life sciences, including human health and rehabilitation. For more information, visit
