Wprowadzenie: Why Biomechanics Matters in Swimming

W ramach tych badań można znaleźć kilka mechanizmów, które pozwalają na uniknięcie zakłóceń, które mogą powodować zakłócenia w zakresie koordynacji, ale nie są one w stanie kontrolować, czy nie istnieją pewne mechanizmy, które mogłyby pomóc w zapewnianiu bezpieczeństwa.

Te Fundamentals of Swimming Biomechanika

At it s heart, swimming biomechanika examinas two interrelated factors: thee forces acting on thee swimmer (hydrodynamics) and thee internal forces produced by muscle andd joints (kinematics and kinetics). A swimmer 's goal is to minimize drag while maximizing propulsion. Understanding these forces allows for properfect ading that improwize ecy, speed, and endurance.

Research using instrumented paddle has shown that elite swite swimmers generate peak force earlier in thee pull compare to novices.
