Too Mentally Fried on a Run? Here’s How to Motivate Yourself to Keep Going
New research shows that motivational self-talk can counter brain drain.
Susanna Sullivan is no stranger to mental fatigue. From late August until early June, the 2:24 marathoner teaches pre-algebra to 104 sixth-graders—which, if you’ve ever dealt with middle schoolers, you’ll know can be exhausting.
“If a student asks, ‘Can I go to the office?’ I immediately have to make all these other considerations: Who else is out of the room? Do I trust the kid to go directly to the office? Are they distressed?” says Sullivan. “By the end of the day, my brain is toast.”
While her non-athletic colleagues may be able to go home and recharge after a long day, Sullivan needs to find a way to rally. Her coach, who is the head coach at George Mason University, holds practices in the evenings. Given that Sullivan is expected to make the American marathon team for the World Championships in August, these workouts matter... whether she’s mentally drained or not.
Much of the prevailing advice recommends doing your best to prevent mental fatigue. For runners like Sullivan, however, prevention isn’t a viable option. In that case, science suggests motivational self-talk might be the solution.
The Problem With Mental Fatigue
Anyone who has had a “long day” knows what mental fatigue feels like: you’re drained, you can’t concentrate, your self-regulation is trashed, and you probably have no interest in going for a run, never mind a hard workout. This comes from putting in the effort to pay attention to something while blocking out distractors—which research shows is tiring and kills your ability to self-regulate.
“There are a certain amount of effs you can give in a day. And if you give them all up, by the end of the day you’ve got none left to give,” says Shannon Baird, Ph.D., a certified mental performance consultant who works with the United States Army Special Forces.
Typically, Baird and others recommend finding ways to pause and recharge throughout the day to avoid creating a mental fatigue “deficit.” If you become mentally fatigued, the most common recommendations are to put off a hard workout or adjust your pace or intervals. Sometimes, however—as in Sullivan’s reality—mental fatigue is unavoidable, and you can’t reschedule. If you hit traffic on your way to a race, for instance, you can’t just move the race to a different day, and you probably don’t want to give up on your goals. In that case, according to a recent study published in the Journal of Applied Sport Psychology, try some motivational self-talk.
Why Motivation Is Important
According to Gleber Pereira, Ph.D., an associate professor in the physical education department at Universidade Federal do Paraná in Brazil and the lead author on the study, motivation is a key contributor to whether or not you’re willing to continue exercising, particularly at a given intensity.
“We have two reasons to explain how you stop or continue exercise: potential motivation, or your willingness to keep exerting yourself in exercise, and motivational intensity, which is how you perceive effort during the exercise,” he says. According to this model, a runner will slow down or stop when their perceived effort matches their level of willingness.
Mental fatigue has a double-whammy effect when it comes to potential motivation and motivational intensity:
First, researchers theorize that it may decrease your potential motivation before you ever start exercising.
Second, it makes you perceive the effort as more difficult sooner than if you were mentally fresh.
Therefore, Pereira and his colleagues hypothesized that if they could manipulate athletes’ motivation levels, they could offset these performance-impairing effects of mental fatigue. They decided to test an intervention that is freely available to every athlete: self-talk.
Testing Motivational-Self Talk
The researchers took 12 men who typically exercised three to five days per week and had them perform three identical cycling tests to exhaustion several days apart. In the first two sessions, participants spent 30 minutes prior to the cycling test either relaxing in a comfortable chair (the control condition) or performing a mentally fatiguing activity called the Stroop task.
During this task, participants identified the display color of words that appeared on a computer screen while ignoring the color that the letters spelled out. (So if the word “red” appeared in green ink, the participant was supposed to press the green button.) The researchers then used a brainwave-measurement technique called electroencephalography and asked participants to self-report their level of fatigue to confirm that, in the mental fatigue condition, they were in fact mentally fatigued.
In the third session, participants were trained how to perform motivational self-talk—essentially redirecting negative thoughts by using short motivational phrases such as “Let’s go!” and “You can do it!” They then performed their final cycling test, which used the same setup as the mental fatigue (Stroop task) condition; this time, however, they were instructed to use motivational self-talk cues whenever they had negative thoughts, felt tired, or otherwise wanted to stop.
It Works!
When the subjects were mentally fatigued, their endurance performance worsened (i.e., they quit sooner) by approximately 19 percent compared to the control condition. However, when the subjects were mentally fatigued and practiced self-talk during exercise, their endurance performance remained similar to the control condition—meaning that despite being mentally fatigued, they were able to maintain their effort for longer.
Pereira and his colleagues speculate that motivational self-talk works in two ways. First, it helps you maintain or increase your potential motivation, i.e., your willingness to exert yourself.
“Mental fatigue may decrease your potential motivation from before you exercise,” says Pereira. “But when you use motivational self-talk, you might increase your willingness to exert.”
Second, it affects your perception of effort. The researchers found that while mental fatigue increased participants’ ratings of perceived exertion (RPE) and feelings of displeasure at the outset of the test (compared to control), the participants reached their peak RPE and feelings of displeasure—which would lead to slowing down and stopping—later in the test when they used motivational self-talk than when they didn’t.
Put another way, motivational self-talk helped them to delay feelings of maximal exertion (“This is so hard, I can’t keep going”) and displeasure (“I hate this, it isn’t worth it”), which improved their performance.
How to Develop Motivational Self-Talk
According to Baird, motivational self-talk is all about manipulating your internal environment.
“Your body is crying for attention because you’re pushing your body. But you don’t have to listen to the thoughts. You don’t have to board that train.” Instead, she says, “you want to facilitate your brain to be an asset, not a detriment.” One way to do that is through motivational-self-talk.
ID Your Negative Thoughts
To replace debilitating thoughts with ones that will enhance your performance, start by identifying the thoughts that are your most common detractors from performance. Maybe they have to do with physical sensations (“This hurts”), boredom (“When will this be over”), or despondency (“I’m a terrible runner; I’m never going to achieve my goal”). Wherever your brain tends to go, you want to be able to quickly recognize these thoughts when the arise.
Choose Motivational Phrases
Once you are prepared to recognize your negative thoughts, write down several motivational self-talk cues that resonate with you. Some examples from Pereira’s study include “Do your best,” “Go to your maximum,” and “Keep going.” He recommends keeping the sentences short and referring to yourself as “you” rather than “I.”
Sullivan finds her motivation in comparing the task at hand to other hard things. “You only have to run for two more minutes” or “Just make it up this hill” works because, as she says, “That seems so much more manageable than 104 sixth graders. A hill is nothing compared to them.”
Practice
Finally, it’s time to practice using your phrases. “Every time your thought goes to some wish to stop or decrease the pace—that’s when you need to use it,” says Pereira. “If you can do it in practice, you can be ready to do it in a race.”
