The training and development process for a world-class female handball player: a longitudinal and retrospective case study.

Introduction: Limited information is available regarding the development of young talents who successfully follow the pathway to professional handball. The aim of this study was to retrospectively investigate the longitudinal training and development process of a world-class female handball player. Methods: An intrinsic case study design was used to capture the quantitative and qualitative aspects related to the training and development process. We used a three-step data collection process and pragmatic analyses of (1) training logs/plans and performance statistics, (2) in-depth semi-structured interviews with three of the player's coaches, and her mother, and (3) systematic quality assurance through interviews to clarify, expand and validate preliminary findings with all informants followed by negotiation among researchers and all key informants, including the player. Results: The player's exceptional performance level was achieved by a gradual increase in training volume from ∼50 to ∼300 h·y Discussion: This study provides novel information regarding the training and development process for a female world-class handball player. The findings may provide a framework for how future talents, as well as their coaches, family, training peers, and national sports federations, can effectively coordinate efforts to enhance long-term athletic development and performance outcomes.
