Understanding the physics of running all comes down to the motion of two body parts, according to researchers at Southern Methodist University.
Their findings published recently in the Journal of Experimental Biology, concluded that running can be explained in a lot simpler terms than scientists previously thought. After examining Olympic-caliber runners, they came up with a “two-mass model” that uses the lower leg that comes into contact with the ground and the sum total of the rest of the body to determine ground force.
“Runners and other athletes can know the answer to the critical functional question of how they are contacting and applying force to the ground.”
“The foot and the lower leg stop abruptly upon impact, and the rest of the body above the knee moves in a characteristic way,” said Kenneth Clark, SMU grad and assistant professor in the Department of Kinesiology at West Chester University, in a release.
“This new simplified approach makes it possible to predict the entire pattern of force on the ground — from impact to toe-off — with very basic motion data.”
The research could have implications on shoe design, injury prevention, rehabilitation practices, and running performance.
“The approach opens up inexpensive ways to predict the ground reaction forces and tissue loading rates. Runners and other athletes can know the answer to the critical functional question of how they are contacting and applying force to the ground,” said Laurence Ryan, a physicist and research engineer at SMU’s Locomotor Performance Laboratory, in a release.

SMU is investing $11.5 million into a powerful new supercomputing research system featuring an NVIDIA DGX SuperPOD. Connected with the NVIDIA Quantum InfiniBand networking platform in SMU's data center, it will produce a theoretical 100 petaflops of computing power—enabling the university's network to perform "a blistering 100 quadrillion operations per second." The new capability will supercharge SMU's AI and supercomputing exploration, boosting North Texas' growth as a technology hub.
Catastrophes like Hurricanes Katrina and Harvey can cause massive human misery and death. With the National Science Foundation grant, SMU Professor Halit Üster will explore ways to use data to help move millions safely out of harm's way—with enough supplies available to meet their needs.
Collectively, the 100 privately held companies contributed $6 billion to the Dallas-Fort Worth economy over three years. Clavis Capital Partners, a private investment firm that operates and grows industrial businesses took the top spot in the annual rankings. Here's the complete list.
Collectively, the 100 privately held companies contributed $8.5 billion to the Dallas-Fort Worth economy over three years—and 10,000 jobs. Frisco-based MTX Group, whose founders were honored last week with EY's 2021 Entrepreneur Of The Year award, took the top spot in the annual rankings. Here's the complete list.
A fleet of 16 autonomous robots from San Francisco-based Starship is now rolling across the SMU campus, delivering food from nine campus eateries. The app-controlled, on-demand robots have Mustang branding and can deliver up to 20 pounds of food in "minutes." Starship, co-founded by a former Skype founding engineer, has made over 2.5 million autonomous deliveries worldwide.
