It is widely accepted that the sources of information used to guide interceptive actions depend on conflicting spatiotemporal task demands. However, there is a paucity of evidence that shows how information pick-up during interceptive actions is adapted to such conflicting constraints. The present study therefore examined the effects of systematic manipulations of spatiotemporal constraints on performance, timing and gaze in an in situ interceptive action. To this end, expert futsal goalkeepers faced penalty kicks taken from 10 m and 6 m...

Despite approval of the use of electronic personal tracking devices (EPTD) during competition by the International Football Association Board (IFAB), other team sport organizations and leagues have banned its use due to "safety concerns", with no evidence to support this assertion. The aim of the current brief report is to provide empirical evidence to support the wide-spread usage across all sports by examining safety issues concerning the use of EPTD in a multi-team sports club. A total of 5 outdoor football teams (first team, second team, under 19, under 18 and first team female) and 3 indoor multi-sport (basketball, futsal and handball) teams have been monitored; accounting for a total of 63...

Small-sided games provide young soccer players with better opportunities to develop their skills and progress as individual and team players. There is, however, little evidence on the effectiveness of different game formats in different age groups, and furthermore, these formats can vary between and even within countries. The Royal Spanish Soccer Association replaced the traditional grassroots 7-a-side format (F-7) with the 8-a-side format (F-8) in the 2011-12 season and the country's regional federations gradually followed suit...

This study aimed to investigate why futsal players decide to dribble. For this purpose, we analysed 396 trials comprising the dribbles (n = 132), passes (n = 131) or shots (n = 133), performed by 70 male futsal players. Passing and shooting angles, and interpersonal distance, including their rates of change (velocity and variability), were regarded as measures of interpersonal coordination tendency and a comparison was made among dribbling, passing and shooting situations. In addition, the variables identified as constraints on deciding to dribble were analysed in relation to age categories, dribbling outcomes and futsal court zone...
