Laboratory, computational and field studies of snowboard dynamics
Buffinton, K. W., Shooter, S. B., Thorpe, I. J., Krywicki, J. J.Published in Sports Engineering (2003)“…In particular, laboratory tests are used to determine the first three bending and first two torsional natural frequencies and modal damping ratios for eight snowboards from two manufacturers. Computer models are developed using the software packages Pro/ENGINEER and Pro/MECHANICA that accurately reproduce the experimentally measured natural frequencies and that facilitate visualization of mode shapes. …”

The variability of visual choice reaction time to different colors in male non-athletes and qwan ki do elite athletes
Cojocariu, A., Ungurean, B.-C., Oprean, A., Puni, A.-R.Published in Archives of Budo (2019)“…Material and Methods: We collected data from 53 male subjects, aged between 19 and 36 years, divided into two groups: the control group (group 1) comprised 46 physical education and sport students (without being performance athletes); the second group comprised seven elite athletes within qwan ki do, members of the Romanian national team, which have attended the latest edition of the European Championship. We have used six computer-based tests, in order to compare the visual choice reaction time (VCRT) to various colors (red, white and blue). …”
