Bilingual Preschoolers Impulse Control
2017/11/23
Preschoolers who speak two languages show less impulsiveness than their single-language peers, say UO researchers whose project was seeded after they met in a graduate psychology course.The UO study, ...
Force-Velocity, Impulse-Momentum Relationships: Implications for Efficacy of Purposefully Slow Resistance Training
Impulse momentum purposefully slow time-under-tension
2015/4/8
The purpose of this brief review is to explain the mechanical relationship between impulse and momentum when resistance exercise is performed in a purposefully slow manner (PS). PS is recognized by ~1...
