Locomotion_And_Fluid_Movement

Locomotion And Fluid Movement The article explains that freestyle is the fastest form of locomotion for fluid movement. The article also discusses statistical testing to understand front stoke in swimming and it mechanical link to the fluid forces required in non-propulsive directions. This examined underlying mechanics of the observed relationships among stoke frequency, stroke length, body roll, and speed. Experimental data was collected from professional swimmers on strategies used to change stroke frequency to swim faster. Stroke frequency is determined by the swimmers desired efforts (Yanai). Three factors are suggested to determine stroke frequency: (a) inertia of the arm about the shoulder, (b) range of motion through which the arm moves, (c) torque applied to the arm though out the shoulder (Yanai). These factors alone do not increases stoke frequency (Yanai). Increase in trunk roll cycle and body roll also will increase stroke frequency (Yanai). It is explained that the trunk roll uses external forces that act in non propulsive directions. This is a constraint to a swimmers propulsion and efficiency (Yanai 2001). These factors have an effect on the swimmers stroke frequency, stroke length, and speed (Yanai). With this in mind Yanai made two predictions (1) body roll frequency, stroke, yanai, body, roll, forces, fluid, swimmers, stoke, effect, article, non-propulsive, directions, about, trunk, shoulder, increased, found, factors, external, arm, very, understand, turning, torque, through, though, technique, speed, sort, research, reduce, participants, needed, movement
