Four Minute Mile Running (4MM)

Project: Research project

Project Details

Description

Aim 1: Enhance a runners speed from a 7 minute/mile pace to a threshold of a 5MM pace (minute/ mile pace) with an objective to increase speed to a 4MM pace. 1. Engineer a powered, elastic hip/knee system to aid in stance and swing phases with the goal of increasing stride frequency 2. Engineer a passive Achilles Tendon spring to aid in propulsion during stance Running poses very difficult challenges. There is nearly a threefold increase in energy required during the ankle gait cycle to transition from walking to running. In addition, the stride frequency nearly doubles, necessitating close to six times the peak power output from the muscle-tendon complex creating a demanding task for anyone. The key question remains can we add passive or active systems to the user to allow a person to run faster knowing that most exoskeleton systems suffer from both increased weight burden and metabolic cost. All human testing will be performed at the Army Research Lab under a separate proposal with guidance from Dr. Michael LaFiandra.

Section II. Summary of Proposal Four Minute Mile Running (4MM) A. Innovative claims for the proposed study Goal of the study: Enhance a runners speed from a 7 minute/mile pace to a threshold of a 5MM pace (minute/ mile pace) with an objective to increase speed to a 4MM pace. Method 1. Refine and test powered actuators that oscillate a mass to assist at the trunk to enhance hopping and running (PogoSuit) Method 2. Redesign passive spring structure at the ankle and refine and test powered hip actuators Running poses very difficult challenges. There is nearly a threefold increase in energy required during the ankle gait cycle to transition from walking to running. In addition, the stride frequency nearly doubles, necessitating close to six times the peak power output from the muscle-tendon complex creating a demanding task for anyone.
