This diary thesis describes the author’s professional and personal development as a strength and conditioning coach in women and girls ice hockey teams. The progression focuses on improving athletes’ experience of physical preparation via improving the communication and stress management of the author. The report consists of daily reports on tasks and objectives, as well as weekly analysis of the work and progression of the author. The diary entries cover a period of 12 weeks of work with two women’s ice hockey teams, taking place between the 6th January 2020 and 29th of March 2020. The author tasks consist of warm-up and physical preparation planning and implementation, as well as athlete monitoring. The report covers three topics within each focus of communication and stress management. In communication the author learns about self-awareness, receivers and context, and in stress management about sleep optimization, meditation and imagery. While challenging to quantify progress in both communication and stress management in the context of a diary thesis, the author self-reports great development in autonomous continued education, as well as discipline and habits to be carried through life beyond the timeframe of this thesis and likely to be contributing to personal and professional growth in the future.
