Teen Pitchers' speed secrets explored in small study
NCT ID NCT07559487
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed observational study measured physical abilities like explosive strength, shoulder flexibility, and sprint speed in six adolescent baseball pitchers over five weeks. Researchers looked for connections between these measures and pitch velocity. No treatment or training changes were tested, so the study only gathers information, not a cure or treatment.
