Background: Despite a substantial body of literature on the physical and technical demands of outfield players in football, there is little information regarding the performance of goalkeepers.   Objective: The aim of this study was to analyse the game performance profiles of goalkeepers at the 2016 European Football Championships.   Methods: A total of 30 goalkeepers from 15 games played during the 2016 European Football Championships were analysed using the InStat® video tracking system.   Results: The results showed that goalkeepers covered a mean total distance of 4819 m, ranging from 4036 m to 6640 m. Overall, 68% of distance travelled was attributed to walking, whereas 0.8% was due to high-intensity activities. The goalkeepers of teams that lost matches covered significantly (p < 0.05) longer distances while sprinting than those of teams that drew or won the matches. Goalkeepers of teams that drew significantly (p < 0.05) had a greater number of passes than those goalkeepers of teams that won or lost.   Conclusion: The current results have implications for soccer coaches to structure training sessions and tactical strategies for goalkeepers. The ability of goalkeepers to meet the physical and technical demands of a match could directly influence the successful execution of skills and the outcome of the competition.

Video Tracking System

Animal models of stroke have been crucial in advancing our understanding of the pathophysiology of cerebral ischemia. Currently, the standards for determining neurological deficit in rodents are the Bederson and Garcia scales, manual assessments scoring animals based on parameters ranked on a narrow scale of severity. Automated open field analysis of a live-video tracking system that analyzes animal behavior may provide a more sensitive test. Results obtained from the manual Bederson and Garcia scales did not show significant differences between pre- and post-stroke animals in a small cohort. When using the same cohort, however, post-stroke data obtained from automated open field analysis showed significant differences in several parameters. Furthermore, large cohort analysis also demonstrated increased sensitivity with automated open field analysis versus the Bederson and Garcia scales. These early data indicate use of automated open field analysis software may provide a more sensitive assessment when compared to traditional Bederson and Garcia scales.

Accurate Quantification

The courtship song of male Drosophila melanogaster Meigen, 1830 is involved in species recognition and sexual stimulation. This signal is usually addressed to the female to reduce her locomotor activity, thereby facilitating copulation. However, no accurate quantification of her locomotion has been made. To examine the effect of courtship song on locomotor behaviour of both sexes, we used a video-tracking system that allowed for the quantification of two indicators of activity level: distance moved and movement duration. First, we showed that the broadcast of the courtship song alone produced no effect on female locomotion. Females reduced their locomotor activity only when acoustical stimulation was placed in a natural courtship context (i.e., in the presence of a male). This suggests that the sum of visual, tactile, acoustic, and chemical stimuli provided by the male may act together to trigger female receptivity. Second, our playback experiments showed a strong stimulating effect of courtship song (particularly of the pulse component) on the locomotor activity of isolated males, suggesting that this signal probably plays a role in male stimulation. Courtship song has an opposite effect on male/female locomotor activity in D. melanogaster.
