End of Summer 2019

The conclusion of spring term and summer 2019 brought many exciting conference appearances, defenses, and graduations for the BSSC crew. Joey Smits successfully defended his Honor’s Thesis project and presented at the University of Oregon Undergraduate Research Symposium. BSSC members also presented at the Northwest Biomechanics Symposium at Montana State University in May. Following shortly after, Evan Day defended his dissertation: The Influence of Internal and External Factors Contributing to Metatarsophalangeal Joint Mechanics and Their Effects on Running Economy. Evan accepted a research position at Adidas in Portland, and although we are sad to see him go, we are excited to see all that Evan will accomplish! Ola Adeniji presented at the International Society of Biomechanics in Sports at Miami University in Oxford, Ohio in July and we were represented by a whopping seven lab members with posters and podium presentations at the International Society of Biomechanics/American Society of Biomechanics Meeting in Calgary, AB in the beginning of August. It was a great conference season for all with exciting science in many different areas! The presentations are listed below:

With a month left until the start of Fall term, the lab is busy finishing up summer projects and preparing for the new school year. Construction on the new Hayward Field is coming along and we will be looking forward to the outdoor track season for the first meets on the new track!

Summer Conferences

With the conclusion of the American Society of Biomechanics meeting this past week, our 2018 conference season has come to an end. It was a very busy one that kicked off early in the year with undergraduates Alex Denton and Sydney Bright presenting at the University of Oregon Undergraduate Research Symposium. Members from the BSSC presented at the Northwest Biomechanics Symposium in Bellingham, WA, the 3-D Analysis of Human Movement meeting in Salford, UK, the World Congress of Biomechanics meeting in Dublin, Ireland, and at the American Society of Biomechanics meeting in Rochester, MN. The work presented spanned numerous disciplines, including prosthesis control systems, use of inertial measurement units, motor learning via use of artificial intelligence, forefoot mechanics during running, and work rate of premier football athletes. The following are all of the presentations.

Undergraduate Research Symposium, University of Oregon
Implementation of Artificial Intelligence in Motor Learning – Sydney Bright
Correlation of Ground Reaction Force Transient Impact Peak and Peak Lower Limb Acceleration in Elite Endurance Athletes – Alex Denton

Both Alex and Sydney continued these projects for their respective honors thesis that they successfully defended.

Northwest Biomechanics Symposium, Western Washington University, Bellingham, WA.
Comparing the time and frequency characteristics of resultant lower limb acceleration and ground reaction force during running – Michael McGeehan
Gait Phase and Locomotion State Estimation from Minimal Sensor Data – Seth Donahue
Modulation of Non-Linear Stiffness in the Foot-Shoe Complex Across Running Speeds* – Evan Day

As the school year looms closer we will be finishing up our lab move to our temporary space for the next two years as the new Hayward Field is being built. Updates to come soon!

Runners Wanted!

Runners wanted! We are conducting a study with an industry partner and need you to run for us! See the attached flyer for more details.

Another Year Come and Gone

The past year has been an exciting one here at the BSSC that has included the beginning of new research collaborations, hosting a conference, and much more!

Jake Hinkel-Lipsker graduated this past June with his Ph.D. and took a position as Assistant Professor at California State University, Northridge. In his place we welcome two new graduate students, Ola and Seth.

We had the pleasure of hosting the Northwest Biomechanics Symposium here at the University of Oregon in May. In July our group traveled to the American Society of Biomechanics conference to present some of the most recent work from the lab. It was a great time soaking up new science, being jealous of the Boulder scenery, and enjoying the company of previous Oregon alumni.

On a very exciting note, this summer marked the start of a new grant funded by the PAC 12 to prospectively research stress fractures in distance runners. We are collaborating with biomechanics labs at University of Southern California, University of Colorado (Boulder), and Stanford University. It has been a very exciting project delving into the use of wearable technology. We look forward to working with the athletes to help inform them about their training and protect them so they can perform at their absolute best.

Over the next year we look forward to continued work with the cross country athletes, keeping busy with our clinic work, and traveling to gorgeous locations for academic conferences!
