Human Muscles, Joints, and Performance

This episode unpacks the roles of tendons, ligaments, and joints in maintaining stability and movement, while addressing common joint disorders like osteoarthritis. We detail muscle contraction biophysics and energy systems, and evaluate how exercise impacts fast- and slow-twitch muscle fibers. Along the way, you’ll discover how physiological adaptations shape performance and why regular exercise matters.
