Determinants of Running Speed

May 1, 2017

Article

Two factors that determine running speed are stride cadence and stride length. Because athletes propel themselves forward only when their foot is in contact with the ground, the stance phase of the running stride should be the focus of speed enhancement programs.

The Need for Speed—Improving Sprinting Performance in Football Players

April 22, 2019

Article Members Only

Acceleration and maximal velocity are two factors that are key for any position in football and can determine success in many situations out on the field. This article will review several aspects of sprint mechanics and training to enhance linear (straight-ahead) speed for football players.

Factors Determining Agility: Speed

June 1, 2017

Article

Acceleration is the rate of change in velocity, so this phase of sprinting is critical for changing directions as rapidly and efficiently as possible. Optimal technique for linear sprinting in the acceleration phase involves four factors that maximize stride length and frequency.

SCJ 46.2 A Conceptual Framework of Different Eccentric Training Methods

Quiz CATD 0.2

Various methods of eccentric training that aim to increase muscle mass or reduce ground contact time during a landing task have been extensively researched and practically examined. However, multiple methods to implement eccentric training currently exist; they differ in execution and intended training adaptions. There is a clear differentiation between an eccentric muscle action and an eccentric motion whereby a motion alludes to a downward movement of an exercise. The proposed eccentric motions are dissipating eccentrics, deceleration eccentrics, overcoming eccentrics, maximal eccentrics, and rebound eccentrics. These motions formulate into training methods and cues to allow practitioners to clearly differentiate the various eccentric training methods used in research and practice. This review proposes a new conceptual framework that clearly outlines the different forms of eccentric motions that fall into a desired eccentric training method.
