Elite wrestler Sakura Motoki (Motoki Sakura) has filled more than 40 training journals over her athletic career. In her own words: “I keep a journal so I do not forget what I have been told. Every day I write one page — things that happened in practice, advice I received, things I noticed, and what I want to focus on next session. Putting my thoughts into words helps me organize what is in my head.”
The Science of Reflection
This kind of deliberate review is known as reflection — the ability to evaluate what one has learned and adapt past knowledge for ongoing improvement. Research suggests two key benefits:
- Applying experience to the future: Past knowledge becomes actionable for upcoming performance
- More efficient learning: Reflection promotes discovery of sport-specific patterns
Research on Junior Athletes (Jonker et al., 2010)
A study of talented junior athletes aged 12 to 16 examined differences in self-regulated learning (SRL) skills: planning, self-monitoring, evaluation, reflection, effort, and self-efficacy.
The key finding: the single skill that most clearly distinguished international-level from national-level junior athletes was reflection. Not physical talent or effort alone, but the capacity to look back and learn from experience.
Summary
Keeping a training journal transforms raw experience into wisdom. Rather than letting a session fade into the past, writing about it allows athletes to carry its lessons forward systematically.
