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.” 

Melissa Jefferson-Wooden delivered a sensational performance in Budapest, storming to victory in the women’s 100m at the inaugural World Athletics Ultimate Championship in a breathtaking 10.62 seconds.

The American produced a superb display of acceleration and composure to claim the World Ultimate Championship title while recording the fastest women’s 100m time in the world this year. Her 10.62 mark underlined her exceptional form and placed her firmly at the top of the global sprinting hierarchy.

Jefferson-Wooden controlled the race through the decisive stages and maintained her form all the way to the finish to secure a statement victory against a field packed with championship pedigree. She crossed the line ahead of Olympic champion Julien Alfred, who clocked 10.74 seconds with a -0.2 m/s wind, while Sha’Carri Richardson took third in 10.76.

Women’s 100m Final

1. Melissa Jefferson-Wooden — 10.62

2. Julien Alfred — 10.74 (-0.2 m/s)

3. Sha’Carri Richardson — 10.76

The victory was especially significant given the quality of the opposition. Jefferson-Wooden held her nerve against Alfred and Richardson, two of the most accomplished sprinters of the current generation, to produce the fastest performance in the world this year when it mattered most.

Alfred once again demonstrated her consistency at the highest level by taking silver, while Richardson completed an all-star podium in a race that brought together three of the biggest names in women’s sprinting.

But beyond the time, the title and the celebration, one of the most touching moments came after the race when Jefferson-Wooden embraced her father, Melvin, in an emotional celebration.

Their moment carried a deeply personal meaning. When Melissa was just 17 years old, she donated her stem cells to help her father undergo a bone marrow transplant after he was diagnosed with myelodysplastic syndrome. Years later, the two shared an unforgettable embrace in Budapest after she had become the World Ultimate Champion.

For Jefferson-Wooden, however, the evening was about far more than a medal. It was the culmination of an extraordinary journey, now highlighted by a world-leading 10.62 seconds on one of the biggest stages in athletics.

With the Ultimate Championship title secured and her father by her side, Jefferson-Wooden leaves Budapest with more than being an ultimate champion. She leaves with momentum, confidence and a powerful statement of intent — turning a high-profile showdown into one of the defining sprint performances of her season.

Audrey Werro has added another major title to her extraordinary season, storming to victory in the women’s 800m at the inaugural World Athletics Ultimate Championships in Budapest.

The Swiss star delivered a commanding performance, taking control from the opening gun and refusing to surrender the lead as she powered through an absorbing battle against two of the biggest names in the event.

Werro stopped the clock at 1:55.88 to become the Ultimate Championships 800m champion, producing another statement performance on one of the sport’s newest and most prestigious stages.

Behind her, Great Britain’s Keely Hodgkinson fought her way to second in 1:56.26, while the Netherlands’ Femke Broeders-Bol completed the podium in 1:56.74.

The result once again brought together the same formidable trio that featured on the podium at the European Championships, but Werro again proved to be the athlete who could rise above the challenge when it mattered most.

Her Budapest triumph is the latest chapter in a season that has already included records, a successful Diamond League Trophy defence and European Championship gold. Now, she can add the Ultimate Championships crown to a growing list of accomplishments.

Werro’s consistency has been particularly impressive in an 800m event packed with elite talent. Rather than simply relying on a fast finish, the Swiss athlete showed her authority by taking the initiative from the beginning and maintaining enough strength and composure to hold off Hodgkinson and Broeders-Bol all the way to the line.

The victory also underlined the remarkable depth of the women’s 800m, with three athletes separated by less than a second at the finish. Hodgkinson’s 1:56.26 and Broeders-Bol’s 1:56.74 showed just how fiercely contested the race was, but Werro’s decision to dictate the pace ultimately gave her the decisive advantage.

For Werro, this was more than another medal. It was another opportunity to demonstrate that her rise is no passing moment. On a stage featuring established champions and elite rivals, she once again produced the performance required to claim the biggest prize.

For Hodgkinson, the silver medal adds another major podium finish, while Broeders-Bol once again demonstrated her ability to compete with the very best over two laps.

But the spotlight in Budapest belonged unmistakably to Werro.

With another championship crown secured, the Swiss star has strengthened her claim as the athlete setting the standard in women’s 800m running. This is Audrey Werro’s era — and the rest of the field is chasing.

Busang Collen Kebinatshipi has delivered another sensational performance, storming to victory in the men’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The reigning world champion stopped the clock at an astonishing 43.39 seconds, smashing his own Botswana national record and moving to fifth on the world all-time list.

Kebinatshipi produced a commanding finish to pull away from his rivals and secure the Ultimate Championship title. American star Rai Benjamin finished second in 44.15, while Jereem Richards of Trinidad and Tobago completed the podium in 44.23.

 Men’s 400m

1. Busang Collen Kebinatshipi — 43.39 NR

2. Rai Benjamin — 44.15

3. Jereem Richards — 44.23

The performance is even more remarkable considering that Kebinatshipi had already rewritten the Botswana record just one week ago in Brussels, where he ran 43.40. In Budapest, he lowered that mark by another 0.01 seconds to establish a new national record of 43.39.

That improvement has also propelled the 22-year-old into rare territory. His latest time now ranks him fifth fastest in history over 400m, placing him among an extraordinary group of athletes who have broken the 43.40 barrier.

Kebinatshipi's victory also caps an extraordinary season for the Botswana star. After establishing himself as a global champion, he has continued to demonstrate that he belongs among the very best one-lap runners in the world.

And there is a major reward for his historic night in Budapest: Kebinatshipi walks away as the Ultimate Champion and $150,000 richer.

From another national record to a place among the five fastest 400m runners ever, Kebinatshipi has turned an already remarkable season into something truly special.

Botswana has its latest sprinting superstar — and Kebinatshipi is showing that his ceiling may be even higher than anyone imagined. 

Marileidy Paulino once again proved why she is the undisputed queen of the one-lap event, powering to victory in the women’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The Dominican Republic superstar produced a sensational 49.07 seconds to claim gold, pulling decisively away in the final straight and holding off a fiercely competitive field to extend her remarkable unbeaten run.

Paulino delivered her trademark combination of controlled speed and devastating finishing strength. She remained firmly in contention through the opening stages before unleashing her decisive move down the home straight, where she quickly opened a gap on her closest challengers.

Norway’s Henriette Jæger mounted a strong challenge but could not match Paulino’s finishing speed, crossing the line second in an impressive 49.28. Jamaica’s Nickisha Pryce completed the podium after clocking 49.56, ensuring that three of the world’s leading 400m talents occupied the medals.

The result once again underlined Paulino’s extraordinary consistency at the highest level. She entered Budapest as the world leader after running 48.48 in Paris in June, a performance that also set a Diamond League record. She subsequently remained unbeaten throughout her Diamond League campaign, closing the circuit with a meeting-record 48.64 in Brussels.

Budapest has also become a special venue in Paulino’s career. Three years ago, at the same National Athletics Centre, she captured her first individual world title, marking the beginning of another dominant chapter in her career. She later added Olympic gold in Paris in 2024, further establishing herself among the defining 400m athletes of her generation.

The inaugural World Athletics Ultimate Championship has brought together the sport’s biggest stars in a new winner-takes-the-spotlight format, with Olympic and world champions, Diamond League winners and leading performers competing for ultimate honours.

For Paulino, the occasion once again ended with Ultimate Crown on her arms.

With 49.07 seconds, she did more than win another major 400m title. She delivered another statement of authority, powering through the final straight with the confidence and speed that have made her one of the most dominant figures in modern women’s athletics.

Marileidy Paulino remains unbeaten, remains relentless and, once again, remains the queen of the one lap.

Jakob Ingebrigtsen has made a major decision regarding the remainder of his World Athletics Ultimate Championship campaign, confirming that he will withdraw from the men’s 1500m in Budapest despite producing a sensational performance to win the 5,000m title.

The Norwegian superstar stormed to victory in the inaugural Ultimate Championship 5,000m on Friday night, clocking a season-best 12:59.24 and delivering a devastating finishing kick to defeat Olympic 5,000m champion Cole Hocker and American Parker Wolfe.

Ingebrigtsen’s final 100 metres was arguably the defining moment of the race. The Olympic champion produced a remarkable 12.60-second closing 100m, powering away from the field to secure the $150,000 winner’s prize and underline just how far his fitness has progressed since returning from Achilles surgery.

The victory was particularly significant after what has been an extremely difficult period for the 25-year-old. Earlier in the season, Ingebrigtsen faced serious uncertainty over whether he would even be able to compete at the highest level again. His return has gradually gathered momentum, and his performance in Budapest offered perhaps the clearest indication yet that the Norwegian is rediscovering his formidable racing ability.

But rather than risk pushing his recovering body further, Ingebrigtsen has now opted to step away from the 1500m.

The decision means the highly anticipated showdown with British rival Josh Kerr will not take place in Budapest after all. The two stars had been expected to renew one of the biggest rivalries in modern middle-distance running in the 1500m final.

Instead, Ingebrigtsen is looking beyond the immediate opportunity and towards the bigger picture.

“I’m thinking about 2027… Fitness cannot be faked,” the Norwegian said, signalling that protecting his long-term condition has become more important than chasing another major victory only days after his return to peak-level competition.

The decision comes just one week after an emotionally charged Diamond League Final in Brussels, where Ingebrigtsen finished fourth in the 1500m behind Australia’s Cameron Myers, Kenya’s Phanuel Kipkosgei Koech and American Ethan Strand.

After that race, Ingebrigtsen delivered a fiery assessment of his rivals and questioned the tactics surrounding the pacemaking, particularly involving Hocker. He later acknowledged that there had been “a little too much adrenaline and emotion” when microphones were placed in front of him immediately after the race.

Yet his latest decision shows that beneath the emotion and competitive intensity lies a longer-term strategy.

Ingebrigtsen has already demonstrated that he can compete at an elite level again. His 12:59.24 in Budapest was not simply a victory — it was a statement that the Norwegian remains capable of producing a world-class finish even after months of injury rehabilitation.

Now, however, he is choosing not to gamble with that progress.

For a runner who has spent much of the year fighting his way back from injury, another 1500m race could have offered enormous rewards but also carried unnecessary risk. By withdrawing, Ingebrigtsen is effectively prioritising longevity over one more opportunity for immediate glory.

His message is clear: the comeback is underway, but it will not be rushed.

The 5,000m victory has given Ingebrigtsen confidence, momentum and perhaps, most importantly, proof that his body can once again handle elite competition.

Now comes the harder part — knowing when to stop.

With 2027 already firmly in his sights, the Norwegian has chosen recovery over risk. And after everything he has endured, that could ultimately prove to be one of the most important decisions of his comeback.

Jakob Ingebrigtsen is not walking away from the sport. He is protecting his future in it.
