Head Impacts in Collegiate Rodeo Athletes: An Observational Study

Brain health has been a growing concern across a wide range of contact sports in the last three decades. While most of the early brain health research was focused on identifying and preventing concussions, newer research has found that an accumulation of repetitive head impacts (RHI) are more predictive of long-term brain health than the number of concussions sustained. Consequently, being able to assess RHI in sports despite the lack of outward symptoms has become paramount in promoting the long-term health of athletes. The sport of rodeo has long been regarded as one of the most dangerous contact sports. While some epidemiological research has been done on injury rates in rodeo that has largely backed up its dangerous reputation, no research has been done into RHI in rodeo athletes.

Head acceleration events (HAE) were measured in collegiate athletes competing in the "Roughstock" events of Bareback Riding, Saddle Bronc Riding and Bull Riding. HAE were recorded using impact monitoring mouthgaurds (iMG) and subsequently confirmed using video verification and submitted to statistical analysis.

Rodeo has a high rate of HAE across all the Roughstock events. The Bull Riding experiences the highest magnitude HAE based on both linear and rotational acceleration. These events are primarily the result of the head impacting either the ground or the animal during the dismount phase of the ride. Bareback riding experiences the highest quantity of lower magnitude HAE which mainly result from whiplash-like movement of the head during the ride.

Rodeo athletes experience a high volume of HAE that often reach concerning magnitude. A surprising amount of the HAE are the result not of impacts, but of the whiplash-like movement that is experienced during the rides.
