| Description | The submitted text inquires ways to utilize a triaxial accelerometer and gyroscope in the area of sports. Previously published findings regard this methodology as very progressive, especially when applied in field research. We constructed a triaxial accelerometer and gyroscope at the Faculty of Sports MU. It is capable of collecting data at 1000 Hz and store it on mini SD card with measuring capacity of 70 hours. The range is ± 16g and it enables to measure rotation 2000°/sec per axis. The size of our accelerometer (60x38x16mm) along with its low weight does not restrict or bother sportsmen during their performance and makes it ideal for measuring in real-life conditions while in training as well as at competitions. Data collected via our accelerometer will have high information value. In the text, there are several measurements from various sports (karate, shot put, cross-country skiing, rowing, gymnastics) presented, that demonstrate the possibilities of kinematic and dynamic analysis of sports locomotion. Data from individual axes, along with summary of data based on tested formula are utilized in the analyses. The calculation of velocity based on the accelerometric methodology has a good value when measuring short and dynamic motion. When measuring long lasting and complex motion, the data tend to be contaminated by error arising from slant of the device and by migration of gravity acceleration in three axes. The methodology based on accelerometer seems to be very topical, yet difficult to interpret during complex motion. |
