measurement method for measuring sport movements. However, these techniques
are expensive, bulky and not portable. A novel inertial data logger designed
to record the linear and rotational movements in three axes at 200 Hz
and save the data on a memory card. A custom PC software was developed
to measure the kinematics parameters (linear and angular accelerations
and velocities) and compute the kinetic parameters (force, torque, angular
momentum, impulse and angular power) of the attached limb during performance.
The current system is applicable in sports that involve high linear and
rotational kinematics and high impact contact. Evaluation of the sensor
module at 500 °/sec showed very good validity and reliability of angular
velocity (r = 0.954, p<0.0001; Cronbachs Alpha = 0.973) and angular
acceleration (r = 0.905, p<0.0001; Cronbachs Alpha = 0.960),
respectively as compared to values obtained at 300 and 210 °/sec.
It is able to measure angular velocity up to ± 100,000 °/sec
and linear acceleration up to 2,452 m/sec2. This is light,
cheap, reliable, robust and accurate system to measure high kinematic
and kinetic parameters in the field. This approach is in contrast to current
high-tech videography systems that are expensive, bulky and cumbersome.
This novel technique is suitable in Soccer, Rugby, American Football,
Tennis, etc. to evaluate the players performance in the field.]]>Aminian, K., B. Najafi, C. Bula, P.F. Leyvraz and P. Robert,20012001pp: 309310Aminian, K., B. Najafia, C. Bülab, P.F. Leyvrazc and P.
