With heightened focus in recent years on the ramifications of concussions on the careers and lives of athletes – especially professional football players – research is gaining interest and attention in a range of contact sports. The recent release of the popular movie Concussion has pushed awareness and interest even further – along with the appetite for scientific research. In Connecticut, Sacred Heart University (SHU) is underway with poised to start the third year of a four-year study of the school’s men’s lacrosse team, which will be among the first comprehensive studies looking at head impact and concussions in the sport at the college level. U.S. Lacrosse, the sport’s governing body, provided the SHU athletic-training education program a $15,000 grant to study the effects of on-the-field head impacts. The 2016 season began on February 13 and runs through April 30.
The SHU study got underway in January 2014 and was initially focused on freshmen players. It has continued to monitor the same athletes as they progress through their four-year lacrosse career. The goal is to gain a better understanding of concussions in the sport and ultimately generate insights for safer play.
Theresa Miyashita, director and assistant professor for the athletic training education program, launched the accelerometer concussion study at the University. The research involves the use of accelerometers in the team’s helmets. These sensors detect the amount of impact (in Gs or standard gravity acceleration) a player receives when he gets hit by a ball, a stick, another player or hits the ground.
“We are one of the first in the country to embark on an accelerometer concussion study of this size in men’s lacrosse,” said Miyashita. “We are collaborating with Professor Michael Higgins at Towson University, who is conducting a similar study to compare impacts on different helmets (Cascade vs. Warrior). This research targets the fastest-growing team sport in America.”
The players have been wearing these sensors in their helmets for the entire season – both in practices and games. The information received from the sensors is then uploaded to see the number of impacts sustained, where the impacts were sustained and the amount of Gs each impact had. This data is then compared to a number of different variables such as neurocognitive function, modified IQ scores, depression/anxiety, alcohol/drug dependency screens and concussion injuries. The players were baseline tested and are given a post-test when each season is complete.
The study is being done in partnership with a Canadian company, GForceTracker, which has developed “an advanced athlete monitoring system used to collect, measure, and analyze head impacts & biometric performance data, all in real time.” The company produces a “Hit Count® Certified, advanced linear g-force and rotational impact sensor monitoring system that accumulates a lifetime of head impacts.”
The detection device monitors, measures and provides vital statistics such as number of impacts, severity of impacts, local alarming when the impact exceeds an acceptable threshold and accumulates this data to provide key metrics that determine whether its user has suffered a possible head injury. The GFT is currently the only Hit Count® Certified head impact sensor on the market, the company’s website indicates, “and can be used by individual players or entire teams in both helmeted and non-helmeted sports.”
“The men’s lacrosse team and their coach, John Basti, have been huge supporters and have been instrumental in getting this project running,” Miyashita said. “This project would not be possible without them and the rest of my research team.”
Miyashita’s team consists of Professor Eleni Diakogeorgiou; Kaitlyn Marrie, staff member for the athletic training program; Mary Jo Mason from the Health and Wellness Center, Professor Kelly Copperthite and a number of her athletic training students. The Fairfield County Business Journal recently reported that Miyashita’s husband is a former professional player who is now assistant coach of the SHU men’s team.
Sacred Heart University, with a student population of 6,400, is the second-largest independent Catholic university in New England, offering more than 50 undergraduate, graduate and doctoral programs on its main campus in Fairfield. The SHU Pioneers' men's lacrosse team competes in the Northeast Conference of the NCAA Division 1.
