Sisetrennidels

Sisetrennidels is a term used to describe an approach in physical training and sports psychology that emphasizes internal aspects of preparation. It combines cognitive strategies, self-regulation, breath control, visualization, and mindful practice with physical drills to enhance focus, consistency, and performance.

The term appears to be of Estonian origin, with “sise” meaning internal or inner and “trenni” referencing training. It is primarily found in Estonian-speaking coaching discussions and online fitness communities, and it is not widely standardized in formal sport science literature.

In practice, sisetrennidels involves setting internal cues, mental rehearsal, and deliberate breath management during training sessions. It may include guided visualization before attempts, attention to body awareness, and reflective self-talk to maintain technique and pacing. The method is intended to be adaptable across a range of sports and fitness activities, from endurance training to resistance work, and can be integrated with traditional external training cues.

Assessment of sisetrennidels is typically subjective, focusing on perceived focus, effort, and adherence to technique rather than standardized metrics. Critics point out the limited availability of rigorous, peer-reviewed research specific to this approach, and caution against relying on unvalidated methods without complementary evidence from conventional training practices.
