A System for Lengthening Contraction Training of Muscle (LCT)

This study is currently recruiting participants.

Verified by University of Michigan, September 2008

Sponsors and Collaborators:	University of Michigan BioLogic Engineering, Inc.
Information provided by:	University of Michigan
ClinicalTrials.gov Identifier:	NCT00575107

Purpose

Evaluation of a new exercise machine designed to improve strength and speed of movement in the leg muscles. Investigators are trying to learn whether a new training method results in greater strength improvements as compared to a traditional method.
