Acceleration Kinematics in Cricketers: Implications for Performance in the Field
Biomechanics cricket fielding step length sprinting swing leg flexion
2015/5/21
Cricket fielding often involves maximal acceleration to retrieve the ball. There has been no analysis of acceleration specific to cricketers, or for players who field primarily in the infield (closer ...
Reliability and Validity of a New Test of Change-of-Direction Speed for Field-Based Sports: the Change-of-Direction and Acceleration Test (CODAT)
Lateral cutting field testing Illinois agility run linear speed team sports
2015/5/14
Field sport coaches must use reliable and valid tests to assess change-of-direction speed in their athletes. Few tests feature linear sprinting with acute change- of-direction maneuvers. The Change-of...

Accelerometry soccer repeatability skill level
2015/5/5
The aims of the present study were to compare the consistency in the lower limb acceleration patterns during inside and instep kicks performed by players with different skill levels, and to investigat...
The Effects of Height and Distance on the Force Production and Acceleration in Martial Arts Strikes
Sports acceleration Kung Fu law enforcement combat
2015/4/30
Almost all cultures have roots in some sort of self defence system and yet there is relatively little research in this area, outside of a sports related environment. This project investigated differen...
Comparability of Measured Acceleration from Accelerometry-Based Activity Monitors
GENEACTIV ACTIGRAPH GT3X+ TIME DOMAIN FREQUENCY DOMAIN
2017/4/14
Background: Accelerometers that provide triaxial measured acceleration data are now available. However, equivalence of output between brands cannot be assumed and testing is necessary to determine whe...

2010/9/9
Researchers have indicated that female soccer players may be at greater risk of concussion compared with their male counterparts. Soccer headgear is marketed for reducing head acceleration and risk of...
Differences in morphological and biodynamic characteristics in maximum speed and acceleration between two groups of female sprinters
Morphological characteristics Biodynamic parameters Start acceleration Maximum speed Female sprinters
2010/9/16
The purpose of the study was to identify those morphological characteristics and biomotor parameters that differentiate between trained female sprinters in terms of 100-m sprint results. Morphological...
