About the lab

Thunder in the human performance lab

In August 2023, the Nora Staeel Evertt Human Performance Lab underwent expansion, funded by a $200,000 SDBOR Research and Development grant. This grant facilitated the construction of a state-of-the-art biomechanics lab and the enhancement of equipment in the existing human performance lab. 

The labs currently serve as crucial research facilities for NSU faculty and students, aligning with the mission to enhance human performance and reduce injury risks in athletes. Moreover, sports science students benefit significantly by gaining hands-on experience with the lab's equipment as part of their curriculum.

This lab expansion holds paramount importance for the university, sports science students, and the community. Given the rapid growth of the sports science field, practical lab experience is often a prerequisite for pursuing a career in this field. The upgraded equipment now enables students to acquire essential hands-on experience, making them eligible for competitive job placements that were previously out of reach. Notably, Northern stands out as one of the only Division 2 universities in the state equipped with a human performance and biomechanics lab of such high caliber, placing our program in direct competition with Division 1 universities at a more affordable cost.

Collaboration Partners

Sanford Health Innovation Center

The partnership involves collaborating closely with a local foot surgeon who has designed a cutting-edge device tailored to amplify intrinsic foot strength. Together, we are conducting comprehensive product testing, delving into various aspects such as functionality, efficacy, and user experience. This effort is also in collaboration with the University of South Dakota. Through rigorous testing and refinement, we aim to ensure that this device meets the highest standards of quality and performance, ultimately offering individuals an alternative solution for enhancing their foot strength and overall athletic performance.

 

Northern State University Football and Women’s Soccer Team

Beginning fall 23 the football and soccer team established a collaboration with the Sports Sciences department, working alongside the strength and conditioning staff to oversee athlete workload. This collaboration involved athletes utilizing the Polar Team Pro sensor during both practices and games. Real-time workload data for each session was monitored by the strength and conditioning staff, while the Director of the lab generated daily and monthly reports to be shared with coaches and the strength staff. A sample report is available for reference.

 

Northern State University Softball Team

The NSU softball team comes into the human performance lab every year for testing at 4 various time points throughout the year. Testing consists of bilateral hip and shoulder internal and external range of motion, body composition scan, quadricep and hamstring strength, and internal and external rotation shoulder strength. These variables are tracked longitudinally and reported back to the coaches and training staff.

The Relationship Between Lower Extremity Stress and Injury Risk in Triple Jump Athletes

The triple jump is an event in track and field that consists of 4 distinct phases; the runup, the hop phase, the step phase, and the jump phase. During the triple jump, the lower extremity must generate and dissipate large amounts of force in both legs during all phases for peak performance and decreased injury risk. As a result of the high forces, triple jump athletes commonly experience shin splints but the etiology of these injuries is currently unclear. For that reason, this project's purpose is to analyze injury risk variables (lower extremity stress, acceleration, and intensity) between the phases of a triple jump. Injury risk variables will be measured using VERT sensors.

The Effects of a Competitive Season on Underclassmen versus Upperclassmen Pitchers (graduate thesis project)

Baseball pitching puts extreme stresses on the arm and body. There has been a massive increase in baseball pitchers getting injured in recent years due to pitchers throwing with higher velocities.. This study is looking at the effects of workload during a season on two groups: underclassmen and upperclassmen. These two groups need to be separated because upperclassmen are generally physically stronger, have more experience, and are smarter about taking care of their bodies. This leads to underclassmen being more vulnerable to getting injured, especially during a competitive season. This study will test pitchers in pre-season, mid-season, and post-season pitching sessions to see how variables can change. Those variables include pitch velocity, pitch spin rate, arm speed, and elbow torque.

The Relationship between the Timing of Hip‐Torso Separation and Hitting Performance

A popular metric analyzed in hitting mechanics is hip-torso separation.  The significance of the degree of hip-torso separation on hitting performance has been researched before with inconclusive results.  Bordelon et al, results suggesting that the timing of which peak hip-torso separation occurs during the swing might be more significant when looking at hitting performance (Bordelon; Washington). The purpose of this study is to investigate the timing at which peak hip-torso separation is reached rather than the degree of separation and its relationship to hitting performance. Hitting performance will be quantified.
