The adjustment of the leg during running was addressed using a spring-mass model with a fixed landing angle of attack. The objective was to obtain periodic movement patterns. Spring-like running was monitored by a one-dimensional stride-to-stride mapping of the apex height to identify mechanically stable fixed points. We found that for certain angles of attack, the system becomes self-stabilize...

PURPOSE The purpose of the present study was to examine relationships between athlete's pacing strategies and running performance during an international triathlon competition. METHODS Running split times for each of the 107 finishers of the 2009 European Triathlon Championships (42 females and 65 males) were determined with the use of a digital synchronized video analysis system. Five camera...

The aim of this study was to quantify the step-to-step variability (SSV) in speed-variant and speed-invariant movement components of the whole-body gait pattern during running. These separate aspects of variability can be used to gain insight into the neuromuscular control strategies that are engaged during running. Ten healthy, physically active, male recreational athletes performed five tread...

INTRODUCTION Many forms of movements were combined with several motor skills, example for catching and passing skills of baseball infields. From the viewpoint of dynamic system theory, these motor skills might be affected by each motor (Newell & Corcos, 1993). For handball players, the skill of moving body and passing the ball were very important. One of the abilities in passing ball was relate...
