Research & Reading
Bowball's check, bounce and wash factors aren't invented metrics — they're grounded in published rowing biomechanics research on boat acceleration and stroke structure. This page collects the external papers and coaching articles worth reading if you want to go deeper than the app's own explanations.
Valery Kleshnev's foundational work on reading boat acceleration as a direct measure of technique — the same signal Bowball's check/bounce/wash factors are derived from.
Analysis of 74 races across single and pair boat classes: deeper maximum negative drive acceleration and greater jerk in late recovery both correlate with faster boat speed, even after controlling for stroke rate and power.
Surveys 27 peer-reviewed studies on on-water (not ergometer) rowing biomechanics, organised around timing, space and force measures, and argues for a standardised on-water assessment framework.
Qualitative study of how expert coaches actually judge technique from the bank — useful context for which biomechanical signals matter enough to turn into automated feedback.
Kleshnev's broader treatment of rowing biomechanics — stroke micro-phases during the drive and recovery, and how they show up in force and acceleration traces.
A coaching-oriented walkthrough of reading force curves through the stroke — the practical, on-the-bank counterpart to the raw research.
Dr. Valery Kleshnev on why the recovery, not just the drive, shapes boat run — directly relevant to Bowball's recovery-phase catch-timing guard.
A coach's-eye breakdown of what a clean catch looks and feels like — the qualitative version of what Bowball's check factor measures quantitatively.
A plain-language walkthrough of the four phases of the stroke — good starting point if catch/drive/finish terminology is new to you.
A rowing-analytics practitioner's review of the standard reference text on the subject, with pointers into the parts most relevant to data-driven coaching.
