Speed and Velocity

Introduction

Speed

Continuing with this small study of different conditional capabilities basic to the development of physical fitness is now the turn of speed, it is defined as the ability to perform motor actions in minimum time, these actions are usually short-lived, produce no resistance or fatigue loads used are of low magnitude.. This is a quality that is highly dependent on the central nervous system due to rapid maturation is one that can work from an early age (Bartram, 2004).

Ratings

Have been developed and identified many different types of speed depending on various factors, some authors focus more on the strength of the velocity component, other component in the resistance, mostly in externals, but the most used on a sporting level is the speed that classifies into three types (Luke, 2000).

Reaction speed: measurable by the reaction time is the ability of motor response in the shortest time possible after the onset of a stimulus, such as the output of a swimmer. Cyclical or displacement speed: the ability to walk a short distance in the shortest possible time as a 100-meter dash. Gestural or acyclic Speed: the ability to perform a fast movement such as a tennis racket hit.

Discussion

Factors of influence

There are several factors that directly or indirectly in this capacity, some are modifiable and therefore trainable so it's better promote the development of speed and strength, power, alactic capacity, flexibility and coordination technique movements, but others are genetic and cannot be varied as the body levers available, fibers or muscle structure, and so on (Redhead, 2004).

Development of speed

The speed training can begin at an early age, particularly the speed of reaction. Levels are increasing speed reaching maximum values around 19 to 24 years. There are various training methods and means of different speeds, in brief and very general we indicate some examples of exercises that will help us improve it: repeats of series (hata 30 seconds) performed at full intensity, practice rises and sets in action starting from different positions, provided races (downhill, with rubber, etc.), maximal strength training and explosive strength, technique exercises.

Velocity

In physics, velocity is defined as the derivative of the position in time, namely the rate of change of the space as a function of time. When not specified for velocity refers to the instantaneous velocity. Speed ??is always a space divided by time, then the IS measured in meters per ...
