AbstractThe objective of this study was to carry out a detailed quantitative analysis of the very high intensity runs during actual play in the 2013-2014 Spanish First Division, at a general level and according to the specific playing position and half. 380 matches of the Spanish First Division in the 2013 - 2014 season were monitored using the Mediacoach video motion analysis tool. Total distance, very high intensity (above 21 km/h) running distance and the number of runs at very high intensity of 230 players from 20 teams in the Spanish First Division were analysed. The main findings of the study were that the performance indicators at very high intensities decreased from the first half to the second half for all outfield players (covered distance: 4694 ± 538 m vs 4485 ± 437 m, sprint distance: 256 ± 72 m vs 239 ± 67 m, number of sprints: 14.3 ± 3.5 vs 13.2 ± 3.1), except the central defenders (sprint distance: 166 ± 37 vs 166 ± 40 m, number of sprints: 10.0 ± 2.1 vs 9.8 ± 3.8). Secondly, although wide defenders (9759 ± 665 m) and central midfielders (9776 ± 942 m) covered the most distance during matches, it were the wide defenders (30 ± 5), centre-forwards (28 ± 7) and wide midfielders (31 ± 8) who performed the most runs at very high intensity. Consequently, the distance they ran at these very high intensity runs followed the same pattern. Such results enable general and specific profiles by demarcation to be established based on the demands of the game at high-level competitive play.

The motility of Azospirillum lipoferum Sp59b and Azospirillum brasilense Sp7 in the presence of the aromatic compounds benzoate, protocatechuate, 4-hydroxybenzoic acid, and catechol was studied using computer-assisted video motion analysis. Increases in swimming speed with concomitant decreases in the rate of change in direction and increases in path linearity are indicative of bacterial chemoattraction. With the exception of 4-hydroxybenzoic acid, the aromatic compounds tested altered the motility patterns of both species, consistent with a chemoattraction mechanism. 4-Hydroxybenzoic acid elicited significant behavioral changes only in A. brasilense. The highest speeds were recorded for most compounds at concentrations between 1 and 10 mM for A. lipoferum and at lower concentrations for A. brasilense. Catechol, supplied at a 10 mM concentration, reduced the swimming speed of A. brasilense but not of A. lipoferum. The distinct differences in swimming behavior observed between these two species of Azospirillum in response to aromatic compounds may be of ecological significance in soils.Key words: Azospirillum spp., motility, video motion analysis, aromatic compounds.

Analysis System

The aim of the study was to verify the application of a three-dimensional video motion analysis system to evaluate maximal fingertip motion area and angular variation of the hand by comparison and correlation with videofluoroscopic analysis. Eight normal subjects were recruited in this study. The maximal motion area of the fingertip and the angles of the metacarpal phalangeal (MP), proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints in performing five sequential postures for functional evaluation of the hand were measured using a video motion analysis system and a fluoroscopy system respectively. The results indicated that the intraclass correlation coefficient (ICC) of the calculated maximal fingertip motion area between the two methods was 0.9597. The ICC for total active motion (TAM) measurements of three finger joints was 0.940 between the surface and bony landmarks by fluoroscopy, 0.952 between the surface landmarks from fluoroscopy and motion analysis, and 0.927 between the bony landmark from fluoroscopy and surface markers from motion analysis. The ICC for angular measurements between three different paired assessments was 0.9650, 0.8896 and 0.8799 for the MP, PIP and DIP joints respectively. The results indicate that motion analysis is a practical method for assessing impairment of the hand.
