Using Biomechanics to Dissect the Energetic Cost of Running
Several task consume metabolic energy during running. The leg muscles must generate force to prevent the leg from buckling as they oppose gravity and inertia. Those forces are also needed to allow tendons to act as springs that store and return energy elastically. The muscles must also generate forward propulsion. Finally, the legs must be alternately swung forward to take the next step. How much energy goes into each task? To answer that question, we perturb normal treadmill running by performing each of those tasks with simple external devices. We infer that the reduction in metabolic cost in response to these perturbations indicates the cost of normally performing the task with muscles. We find in general that vertical weight support and forward propulsion are intrinsically coupled and that each comprises a similar fraction of the overall cost of running (~40% each). Leg swing is relatively cheap (~10% of the total). Some of our devices are proving to have useful applications to helping patients with locomotion rehabilitation.
Student Presentations:
Podium: Each session is organized to include presentations along similar threads to facilitate discussions. Undergraduate and graduate students will present their research for 10 minutes with 5-minutes of discussion and questions. A computer projection system will be provided as well as a computer with microsoft PowerPoint. You may also bring your own computer if you wish. If you have any additional audiovisual needs, please contact us as soon as possible. We ask that the presenting author be at the lecture hall at least 10 min before the start of the session.
Poster: Posters are to be a maximum or 3 feet (90 cm) wide and 4 feet (120cm) tall. They are to be posted in the common area of the Knight Law Center before 3:30 pm on Fri and to be taken down before 1:45 pm on Sat.
Round Table Discussions: Following each student presentation session, all participants will be divided into small groups for continued discussion on the research thread presented. These groups (10-15 participants each) will encourage broader interaction and detailed discussion of methods and results.
Northwest Biomechanics Symposium Outstanding Awards: These two awards will be presented to the most outstanding podium presentation and poster presentation during this meeting in the amount of $200 and $100, respectively. The awards will be based on both the submitted abstract and the presentation.
Awards are sponsored by MEA Forensic Engineers & Scientists Ltd 
Dinner Friday Night: Please join us for dinner Friday night at the UO Casanova Center - Pittman Room. This will be an excellent opportunity to continue discussions, make connections, and relax with colleagues. This dinner is included with registration.
The Casanova Center is located next to Auzen Stadium. Driving Directions
