The ability of tendons to buffer energy during eccentric contractions depends on lengthening dynamics
Meeting Abstract 118-5 Sunday, Jan. 7 09:00 – 09:15 The ability of tendons to buffer energy during eccentric contractions depends on lengthening dynamics ROSARIO, MV*; ROBERTS, TJ; Brown University; Brown University michael_rosario@brown.edu http://michaelvrosario.com When muscle-tendon units (MTU) absorb energy via active lengthening, energy flows into an elastic tendon before being dissipated by the muscle. Energy flow into […]
