Marine Training May Take More Mental Than Physical Stamina

A new study suggests that when it comes to getting through Marine Corps training, psychological factors may matter more than physical performance outcomes.

The U.S. military has an ongoing need for service members who can serve in elite and specialized military units, such as the Marine Corps. However, the dropout rate for these forces is high because of the very rigorous training.

To help determine predictors of success or failure in elite military training, Leslie Saxon, MD, executive director of the University of Southern California (USC) Center for Body Computing, and Center for Body Computing researchers monitored the physical and psychological activity of three consecutive classes of Marines and sailors enrolled in a 25-day specialized training course.

The findings are published in the Journal of Medical Internet Research mHealth and uHealth.

A total of 121 trainees participated in the study, but only slightly more than half (64) successfully completed the course.

Overall, the researchers found no link between finishing the course and performance on physical training standards, such as hikes or aquatic training. Physical markers such as heart rate or sleep status also did not play a role.

Rather, the biggest determinant was mental. Trainees who identified themselves as extroverted and having a positive affect — the ability to cultivate a joyful, confident attitude — were most likely to complete the course.

“These findings are novel because they identify traits not typically associated with military performance, showing that psychological factors mattered more than physical performance outcomes,” says Saxon, who is also a cardiologist with Keck Medicine of USC and a professor of medicine (clinical scholar) at the Keck School of Medicine of USC.

In addition, the researchers were able to identify psychological stressors that triggered dropping out of the course. Trainees typically quit before a stressful aquatic training exercise or after reporting an increase in emotional or physical pain and a decrease in confidence. This led researchers to be able to predict who would drop out of the course one to two days in advance.

While Saxon has been studying human performance in elite athletes for 15 years, this was her first study involving the military. She partnered with the USC Institute for Creative Technologies, which has established military research programs, to run the study with a training company in Camp Pendleton, Calif. that trains Marines in amphibious reconnaissance. Typically, only around half of the participants finish the training.

Before the trainees took the course, the researchers had collected baseline personality assessments, evaluating personality type, emotional processing, outlook on life and mindfulness. Researchers next provided subjects with an iPhone and Apple Watch, and a specially designed mobile application to collect continuous daily measures of trainees’ mental status, physical pain, heart rate, activity, sleep, hydration and nutrition during training.

The mobile application also prompted trainees to answer daily surveys on emotional and physical pain, well-being and confidence in course completion and instructor support.

“This study, the first to collect continuous data from individuals throughout a training, suggests that there may be interventions the military can take to reduce the number of dropouts,” says Saxon.

“This data could be helpful in designing future training courses for Marines and other military units to increase the number of elite service members, as well as provide insights on how to help athletes and other high performers handle challenges.”

Saxon is already testing whether various psychological interventions or coaching might encourage more trainees to stay in the course.
