Innovative wireless measurement system allows researchers to isolate biomechanics, joint torque and muscle function on the slopes

VAIL, Colorado (December 7, 2015) — Opedix, a leader in kinetic health gear, announces the findings of a 2015 University of Denver study, demonstrating that its KNEE-Tec 2.0 tights reduce peak torque on skiers’ knees by 16 percent and contribute to improvements in athletes’ efficiency on the mountain.

Opedix partnered with the University of Denver Human Dynamics Laboratory during the 2014-15 ski season to better understand the mechanics behind the performance of its unique KNEE-Tec 2.0 tights. The tights, available in full- and ¾-length, feature a patented combination of compression and tension to reinforce joints and reduce muscular fatigue.

Using slalom race simulations conducted with nine study-blind athletes from the university’s multiple-time national champion alpine ski team, the study showed that racers wearing KNEE-Tec 2.0 tights were able to achieve greater hip flexion at the initiation of the turn, resulting in a 10-degree greater edge angle, as well as 17-percent less quadriceps activation to steer the skis. Athletes wearing Opedix tights saw peak knee torque reduced by 16 percent over their control results.

“Athletes were able to complete the turn phase faster, with reduced effort and less load on their joints. This research proves what we have known all along: wearing Opedix KNEE-Tec 2.0 tights can help you have a better day on the mountain,” says Vice President of Business Development Brian Cousins. “The benefits of our kinetic health gear are as applicable to the recreational skier, who may fatigue over the course of a full day on the hill, as they are to the champion racers who took part in this experiment.”

By allowing the test subjects to use their own equipment and perform trials on a standard slalom course in consistent conditions, researchers were able to isolate the effects of the technology within the Opedix KNEE-Tec 2.0 tights versus standard compression tights. 

In order to measure joint torque and muscle function outside of a traditional laboratory setting, the team at D.U. developed an integrated wireless system incorporating 15 inertial measurement units, a global positioning system, electromyographic sensors, pressure insoles, and an onboard processor to measure acceleration, speed, joint angles, ground reaction forces and muscle activation.

“Recent advances in wireless sensor technology and computer processors have finally made it possible to precisely study the biomechanics of athletes in their natural environments, beyond the confines of the laboratory,” says Michael Decker, Ph.D., a senior scientist at the Human Dynamics Laboratory at the University of Denver.

The KNEE-Tec 2.0 tights are available online now, at MSRP $195. To learn more about Opedix products or to purchase, please visit
