Uses of 360° video in referees' reflectivity training: Possibilities and limitations.

Introduction: A pedagogical innovation backed by an online device using 360° video had been devised to train young team sports referees (handball, soccer, rugby) to be more reflective. The objective of this exploratory research was to investigate the ways young student referees use 360° videos in allo-confrontation when carrying out some exercises involving open questions about their viewing experience.

Methods: Student referees' answers were recorded.

A study of the individual activity of professional volleyball players: Situation assessment and sensemaking under time pressure.

The aim of this study is to understand interindividual differences in defensive behaviour in elite volleyball players facing similar game situations. This recurrent observation leads us to adopt an activity-centred ergonomic approach. Two case studies are conducted in naturalistic contexts.
