Professional sports have always embraced innovation, but today's competitive advantage increasingly comes from science. Researchers are applying advances in neuroscience, artificial intelligence, biomechanics, data analytics, and human performance to better understand how athletes make decisions, respond under pressure, recover from injury, and maximize performance. What once relied heavily on intuition and experience is now being informed by sophisticated research that can measure, predict, and improve outcomes at every level of competition. Recent studies from Carnegie Mellon University highlight the growing role science is playing across the sports landscape. Whether examining decision-making in high-pressure situations, analyzing performance strategies, or using artificial intelligence to improve health outcomes, researchers are uncovering insights that can help athletes perform at their best while extending careers and reducing injury risk. Ron Yurko is an Assistant Teaching Professor in the Department of Statistics & Data Science at Carnegie Mellon University, and the Director of the Carnegie Mellon Sports Analytics Center (CMSAC). View his profile Scott Powers, an assistant professor at Rice University with vast front-office experience in Major League Baseball—including stints with the Los Angeles Dodgers and the Houston Astros—joined forces with Ron Yurko, a director at the Carnegie Mellon Sports Analytics Center, to analyze this cutting-edge data. Their study, published in The American Statistician in 2026, marks a significant advancement in the quantitative understanding of batting dynamics. It uses high-resolution measurements of bat speed and swing length, metrics that were publicly released for the first time in 2024, to explore how hitters modulate their swings under different pitch counts, particularly when facing two strikes. Eric Yttri is an Associate Professor at Carnegie Mellon University where his research goal is to establish how neural circuits lead to these action selection decisions. View his profile As a neuroscientist, I have been working to uncover how the brain decides when to act and when to wait. Recent research from my team and me helps explain why this split-second pause happens, offering insight not only into elite athletic performance, but also how people make everyday decisions when the potential outcome isn't clear. We found that the key to hesitation is a response to uncertainty. This could be where a dropped hockey puck will land, when a race starts, or placing your order at a new restaurant. Eni Halilaj is an Associate Professor at Carnegie Mellon University where she directs the CMU Musculoskeletal Biomechanics Lab, an interdisciplinary group of engineers seeking to understand and optimize human movement mechanics. View her profile According to Eni Halilaj, an assistant professor in mechanical engineering at Carnegie Mellon University and biomechanist who specializes in orthopedic rehabilitation, 60 percent of those who suffer this common knee injury also develop osteoarthritis early in life. The degenerative joint disease, which affects an estimated 32.5 million individuals in the U.S., is especially problematic for younger patients because of the longer time span during which the chronic condition can cause debilitating pain, stiffness and limited mobility. "How can we make the 60 percent have the same long-term outcome as the 40 percent?" asked Halilaj, who is working to understand the difference between those who do and those who do not develop osteoarthritis following knee trauma. Matthew Walker is a Professor, Astrophysics & Cosmology at Carnegie Mellon University. His research focuses on the astrophysical properties of dark matter, but he is also a former collegiate D1 baseball player and lifelong, passionate fan staying apprised of advancements in the game. View his profile Carnegie Mellon University physics professor Matthew Walker said the system still has limitations, especially on pitches that are extremely close to the edge of the strike zone. "Every measurement device has a margin of error," Walker said. "ABS is, from what I can tell, somewhere around half an inch -which means if the ABS call says that the pitch was within half an inch of the border between a ball and a strike, whether it says it’s a ball or a strike is really no better than a guess." Walker said that in those situations, the umpire’s original call should remain in place rather than letting the automated system make the final decision. The influence of science in sports extends far beyond professional athletics. Research developed for elite competitors often finds applications in healthcare, rehabilitation, education, workplace performance, and everyday decision-making. As teams continue to invest in analytics, wearable technology, artificial intelligence, and performance science, the relationship between research and sports is expected to grow even stronger. The result is a deeper understanding of how humans learn, adapt, compete, and perform under pressure. If you're covering or looking to know more, we can help!
