Patriot Performance Lab helps athletes stay in the game Sarah Holland Tue, 03/03/2026 - 12:52

To be an NCAA Division 1 student-athlete, you need a village. From dieticians to strength trainers to physical therapists, developing and maintaining fitness for elite competition is a collaborative effort. One way that �鶹��Ƶ Intercollegiate Athletics and the College of Education and Human Development (CEHD) keep our athletes in top form is through evidence-based practices and science. That's where the Patriot Performance Lab comes in.

The Patriot Performance Lab’s role is twofold: They monitor and measure athletes’ health as well as conduct research studies on athlete performance. Over the years, they’ve conducted numerous studies with various D1 teams—such as testing vitamin D levels in basketball players and knee joint adaptations in volleyball players—while providing athletes with critical data on their health metrics like body composition, VO2 Max, strength measurements, and more.

“We’re not just a research lab,” emphasized Margaret Jones, professor in CEHD’s Sport, Recreation, and Tourism Management Division and director of the Patriot Performance Lab. “Providing health services to athletes is also critical. It’s what makes the partnership work.”

Strong science communication skills are essential in this field. Researchers need to be able to translate data and results to coaches and student-athletes so they can adjust and improve. Chris Green, professor of sport management and director of the Center for Sport Management, works with the lab to help staff develop research communication skills.

“It’s relatively new to consider sports management in sports science,” she said. “The field as a whole is starting to ask how we can make good management decisions around athlete health and performance data. But the Patriot Performance Lab is already doing this work. It’s one of the things that makes us unique, and it’s what makes our work impactful.”

Green has been essential, Jones said, in helping lab members develop their communication skills and better understand how information is being shared from researchers to coaches to athletes.

“When they understand why I’m asking them to wear or do something and understand how this will benefit them, they’re more likely to perform at the level required in order for us to get good data,” said Noelle Saine, BS Kinesiology ’22, MS Kinesiology ’23, and a third-year PhD student. Saine, who was herself a student-athlete in track and field, understands the importance of strong communication between sport scientists and athletes.

“It’s establishing trust that what we’re doing will improve their health and performance,” said Jones.

Collaboration with the coaches and athletic trainers is also critical. “We couldn’t do what we do without them,” said Saine. “They see the benefits and importance of what we do.”

Postdoctoral research fellow Erica King, BS in Bioengineering ’21, PhD Bioengineering ’25 and a former student athlete in swim and dive, has been leading the work on knee joint adaptations since she was a graduate student. She led a recent 9-month study using wearable sensors for tracking load during practice, counter-movement jump testing, wearable and clinical ultrasound, MRIs, and surveys to assess the load demands on volleyball players’ knees.

“At the end of the season, we were able to show the coaching staff the average number of jumps athletes complete in a 15-16 week period and the direct effects of that from a joint adaptation standpoint,” she said. “They found that data really helpful, and now they can tailor practice sessions to better support the players and help alleviate strain that could lead to injury.”

Athletes, coaches, and athletic trainers often come to the lab with questions for study and ideas. A blood lactate study with the swim team last spring was requested by the swimmers, who applied for and received an Office of Student Creative Activities and Research (OSCAR) grant to fund the study. The team collected data from blood draws, heart-rate monitors, DEXA scans, and jump testing. Early review suggests athlete stroke specialization and maximal power generation capabilities significantly impact accumulation in blood lactate levels during all-out swim bouts.

And as Saine and King can attest, the Patriot Performance Lab offers George �鶹��Ƶ students the opportunity to do hands-on research in a wide range of fields. There are opportunities for all levels of research, from postdocs like King to high school students interested in exploring this world of research for the first time.

“Having that R1 designation really gives us the extra push to be able to dive deep into research,” said Saine. “Faculty have always encouraged me to find what I’m passionate about and pursue it. And my experience has been that instead of being competitive, everyone wants to work together to push forward and improve.”

Green noted that Jones’ experience as both researcher and practitioner is also an important piece of the puzzle that makes the Patriot Performance Lab work. “[Jones’] capacity to connect all these parts and have both credibility and an understanding of what the needs are sets us apart,” she said.

Jones said she appreciates the openness and willingness of people at George �鶹��Ƶ to work together.“We’re supported on both sides by CEHD and Athletics.”

“The Patriot Performance Lab reflects what George �鶹��Ƶ does best, bringing research and practice together in service of people,” said Ingrid Guerra-López, dean of CEHD. “Our student-athletes are performing at the highest levels, and they deserve evidence-based support that protects their health and enhances their performance. This partnership between CEHD and Athletics ensures that science goes beyond the lab, to directly improve lives.”

Using virtual reality to prevent falls in older adults

Katarina Benson — Tue, 01 Jul 2025 18:51:03 +0000

Using virtual reality to prevent falls in older adults Katarina Benson Tue, 07/01/2025 - 14:51

Annually, one in four senior citizens seek emergency care from a fall-related injury. Traditionally, conventional physical therapy rehabilitation approaches have been used to help prevent falls, which are often the result of poor balance. However, many in the physical therapy field now view immersive virtual reality (VR) technology as an intriguing option. While laboratory-based experiments provide promising findings, to date this technology has yet to be translated into clinical settings.

Tiphanie Raffegeau of �鶹��Ƶ ’s School of Kinesiology in the College of Education and Human Development, and Christopher Rhea, Old Dominion University’s associate dean for Research and Innovation in Ellmer College of Health Sciences, envisioned a future where clinicians could use affordable VR technology to outperform traditional diagnostics, therapeutics, and pharmaceutical approaches in fall prevention. They saw an opportunity to develop effective uses of VR technology to detect cognitive-motor function in older adults and identify fall-risk factors for this population. They were awarded a 4-VA grant for the project.

Raffegeau’s prior research focused on inducing anxiety during walking to study the fear of falling with an elevated height VR paradigm, while Rhea has primarily concentrated on examining how people adapt their steps to avoid obstacles in virtual environments. Through a 4-VA partnership, they aimed to increase accessibility to rehabilitative VR technology for interventions focused on reducing older adult fall-risk, while developing a framework for future scalable and fundable research.

Raffegeau hired three student programmers, Trevor Hsu, Chara Canfield, and Micah D Williams, from George �鶹��Ƶ’s Virginia Serious Game Institute (VSGI) to help. The student programmers were supervised by VSGI research faculty member Jacob Enfield. Two �鶹��Ƶ graduate students are also working on the project: Kelly Poretti and Mackenzie Barrowman.

After a year of research, Raffegeau noted, “Our testing proved fruitful, and we identified a number of important results.”

First, they found that experiencing fall-related anxiety in immersive VR can further impair a senior’s walking performance. Interestingly, they also found that the anxiety response tapers over time, suggesting that experiencing virtual high-elevation settings may reduce fall-related anxiety overall. They also saw that anxiety-provoking VR settings could promote stability-related adaptations during non-VR walking in impaired populations. This suggested that the VR experience could serve as a clinical intervention to improve walking.

They shared their findings at the Gait and Clinical Movement Analysis Society’s annual meeting, the American Society of Biomechanics annual meeting, and the College of Education and Human Development’s Research Symposium.

Poretti, who is working on a PhD in Education, was awarded the Switzer Research Fellowship for Doctoral Dissertation Research by the Administration for Community Living for her dissertation “Using Virtual Reality to Reduce Mobility-Related Anxiety in Lower-Limb Prosthetic Users,” which uses preliminary data from the VR project.

“This 4-VA funding provided crucial funds to support my work as an early investigator, and it has made my future grant applications stronger as evidence of institutional support for my career trajectory,” Raffegeau said.

Raffegeau and Rhea will continue to pursue this line of research. They recently submitted a proposal to the National Institutes on Aging on “Investigating Biobehavioral Responses to Mobility-Specific Anxiety Across the Menopause Transition and the Effects on Mobility and Fall-Risk,” focusing on the effect of VR-induced fall-related anxiety on walking in pre- and post-menopausal older women.

Through NSF funding, graduate students and community partners find novel solutions to public health problems

Through NSF funding, graduate students and community partners find novel solutions to public health problems Sarah Holland Fri, 06/21/2024 - 12:18

One of the ways �鶹��Ƶ is All Together Different is its approach to research. Students in the Center for Adaptive Systems of Brain-Body Interactions (CASBBI) NSF Research Traineeship (NRT) Program learn how to apply interdisciplinary, community-focused research to find solutions to the world’s grand challenges.

Since the program began in 2019 with the support of the National Science Foundation (NSF), the NRT Program has bought together graduate students from engineering, data science, and social science for one-year fellowships. Students work in multidisciplinary teams of other fellows and community partners to define a problem within the community and co-develop creative solutions. Thus far, 82 graduate students have participated in the five cohorts.

“No one is doing this level of interdisciplinary convergence,” explained Samuel Acuña, research professor in the Department of Bioengineering and assistant director of CASBBI. “You'll see other programs with, say, mechanical engineers working with electrical engineers, but we have groups with computer scientists, social workers, and linguists working together. Psychologists, engineers, and neuroscientists. It’s novel.”

In the program, students are assigned to groups and matched with community partners working to solve public health problems. The groups work with these partners to establish a project that will best meet their needs: This could be anything from data collection to mobile application development to further developing the work of the previous cohort.

Some groups have even continued their work long after their time in the program concludes; iConnect, an app to connect those suffering from substance abuse to local resources and support, continues beyond the program with their community partner The Chris Atwood Foundation.

“To have, say, a computer science student work with the community and think about people and problems in a way they wouldn’t otherwise, that’s the type of experience that they can draw on for years and years to come,” Acuña said. “The fellowship helps them think more deliberately about how they approach their research through a toolbox of techniques. So, when they’re done, they can approach any issue or problem they might be assigned from this perspective.”

Community-centered and human-centered research is a big draw for some NRT fellows. Morgan Lamarre, BA Dance ’22, BS Bioengineering ’24, master’s student in bioengineering and a member of the 2024-25 cohort, said, “Many of us hope that our careers are in community-facing work, so to have these skills and experience in engaging with the community will be really helpful. And these methods are different from what we see in our classrooms and labs.”

“As engineers, we’re often given a problem to solve how we want and how we think is best without input from the community, and there’s a bit of mistrust between the overall community and the scientific community as a result,” said Kirubel Tadesse, BS Bioengineering ’24, current master’s student in data analytics engineering and incoming cohort member. “But through this method, we’re actively engaging with the community and stakeholders to ensure that our designs are meeting their specific needs. We’re bridging that gap.”

“It’s a completely new way for us to approach our work,” said Brady Stinson-Smith, master’s student in bioengineering, and fellow member of the incoming cohort. “We can be so siloed in our fields, but this program helps us make the connections between not only the community, but also with researchers in other fields like sociology, psychology, and social work who can help us think better and differently about our approaches and solutions.”

This is the philosophy upon which the NRT program is built. “No one field is enough to solve these problems,” said Acuña. “The leaders of tomorrow need to know how to navigate across multiple disciplines and groups of stakeholders in order to create impactful change.”

“We all come from different approaches,” said Yosef Shaul, PhD student in kinesiology and 2023-24 cohort member. Shaul was a member of team VIRTUE (Violence Intervention and Resolution through Unifying Efforts), focused on addressing barriers to domestic violence prevention and management in Northern Virginia. “Everyone brings their own advantages and attributes. It makes the whole greater.”

Now that he has completed the fellowship, Shaul plans to adjust his research process for his PhD to incorporate more community-centered practices. “My outcomes,” he said, “will now better meet community needs.”

�鶹��Ƶ research takes a SMART approach to tactical athlete fitness

�鶹��Ƶ research takes a SMART approach to tactical athlete fitness Sarah Holland Tue, 04/09/2024 - 16:31

From dietitians to personal trainers, it takes a team of experts and specialists to keep professional athletes strong and healthy throughout their careers. But Joel Martin, associate professor of kinesiology in �鶹��Ƶ’s College of Education and Human Development, thinks there’s one group of athletes missing that same level of support: tactical athletes.

“Tactical athletes are those in professions where physical fitness is a critical component, but who aren’t sport athletes,” Martin explained. This includes military, law enforcement, and first responders. Through the Fit2Serve program, Martin hopes to give tactical athletes the support and resources they’re missing.

Fit2Serve began through an Office of Student Scholarship, Creative Activities, and Research (OSCAR) summer impact grant. Martin works with student researchers in �鶹��Ƶ’s Sports Medicine Assessment Research and Testing (SMART) Lab on the SciTech Campus to provide fitness testing and wellness resources for tactical athletes and looks for solutions for their specific challenges.

“I think a lot of us know someone involved in military or emergency response,” Martin said, “and we don’t always appreciate the challenges those professions experience, both day-to-day and long term.”

Fitness, Martin said, is more than exercise—sleep, diet, mental wellness, and everyday physical activity all play a role. By improving overall fitness, Martin hopes to improve tactical athletes’ ability to complete occupational tasks and their health and longevity, as well as prevent injuries. For firefighters especially, there is a critical need for better resources, education, and research in these areas.

“Post-retirement mortality rates for firefighters are, on average, much higher than the rest of the population, due to the high physical demands of their jobs, high potential for injury, and consequences of poor sleep and wellness while on active duty,” Martin said. “We want to improve that statistic.”

His research team uses tools such as sleep surveys and real-time fitness monitoring during training exercises to make holistic recommendations for first responder wellness strategies.

“It’s useful for them to understand the physical demands of what they’re doing in order to make more informed decisions that will hopefully prevent extreme fatigue and injury in the long run,” Martin explained.

Their work is already making an impact. After a controlled burn training with the Fairfax County Fire and Rescue Department, for example—where Martin and his team examined the extreme physical load placed on the individuals setting up the burn using wearable biosensors—they were able to provide objective data to support a command decision by the fire department to reduce the length of the training from full days to half days. Martin hopes that an upcoming load monitoring study will lead to firefighter schedule adjustments to prevent extended sleep deprivation; many work 24-hour shifts, which leads to disrupted sleep cycles and degraded fitness. This study will be the dissertation for PhD student Mike Toczko.

Another arm of Martin’s work is closer to home—right on the Fairfax Campus, in fact: �鶹��Ƶ’s Army ROTC program. He credits current PhD student Megan Sax van der Weyden for rebuilding the bridge between the SMART Lab and ROTC through their incorporation into the Fit2Serve program.

Sax van der Weyden applied for �鶹��Ƶ’s PhD in Education with a specialization in kinesiology because of the department’s established research with tactical athletes. As both a former student-athlete and ROTC cadet, she hopes to reduce the disparities between the available resources for these groups.

“[As a student-athlete] I had dietitians, sports doctors, mental health counselors, and specialists creating our fitness plans and giving us pre- and post-workout routines,” she said. “For ROTC, you only had the upper-level cadets giving out whatever advice they had gotten from their upper-level cadets.” More formal education backed by research would help to prolong cadets’ military careers and reduce risk of injury, she said.

After graduating, Sax van der Weyden will serve in the Army, where she hopes to put this experience to use.

“It’s been a really good learning experience figuring out how to work with large groups of research subjects and even larger data sets. And it’s good practice for distilling complicated theories and information into digestible components for an uninformed audience,” said Sax van der Weyden.

Along with providing fitness testing and health surveys for the battalion each semester, Sax van der Weyden delivers presentations on the importance of diet, fitness, and sleep, and is currently working on an online learning database for tactical athletes that she hopes will last long beyond her time at �鶹��Ƶ.

Martin said many students find the Fit2Serve program provides them with a new outlook on how they can make an impact.

“I see a lot of students come into the kinesiology program thinking they want to do sports medicine, and then transition to tactical athlete research after working with emergency responders,” Martin said.

“It makes me smile watching them learn that they can make a difference in this field.”

�鶹��Ƶ is one of 156 universities and colleges around the world to be honored by Exercise is Medicine^® for its efforts to create a well-being culture on campus. The silver rating highlights campuses that engage students, faculty, and staff in education initiatives and make movement part of the daily campus culture.

University-wide initiatives that contributed to the rating include the �鶹��Ƶ Nation Thriving Together 5k, a �鶹��Ƶ Exercise is Medicine Instagram account, and other activities including fitness webinars, bingo, and an exercise is medicine walk led by a health and fitness professional.

In summer 2021, Debra Stroiney, EIM-OC advisor in �鶹��Ƶ’s School of Kinesiology, partnered with Becky Demus, assistant director of fitness at �鶹��Ƶ Recreation, to form �鶹��Ƶ’s first EIM-OC leadership team. The team includes faculty, staff, and students who want to help promote how exercise is in fact medicine.

Demus said the team has formed strong partnerships across campus to help educate students on the importance of physical activity.

“We want to spread the word to the �鶹��Ƶ community that exercise should be thought of as medicine, and that you can make exercise work for you—in a way that fits your schedule and is enjoyable,” Demus said.

One goal of the leadership team is to establish a health assessment program that will be accessible on all campuses, as well as a referral program with Student Health Services and Counseling and Psychological Services.

“With this team we are working to increase the visibility of this important initiative on all campuses,” Stoiney said.

The program recognized 156 colleges and universities this year, with 73 earning gold, 50 earning silver, an 23 earning bronze recognition. All 156 will be recognized on June 1 as part of the 2022 Exercise is Medicine World Congress, held in conjunction with the American College of Sports Medicine’s Annual Meeting.

“We are thrilled to recognize these campuses’ commitment to make movement a part of daily campus culture and give students the tools to cultivate physical activity habits that will benefit them throughout their lives,” said Robyn Stuhr, vice president of Exercise is Medicine.

The American College of Sports Medicine co-launched Exercise is Medicine® in 2007 with the American Medical Association. EIM-OC, which launched in 2014, calls on universities and colleges to promote physical activity as a vital sign of health, and encourages faculty, staff, and students to work together to improve their campus community’s health and well-being.
