I chuckle each time I hear the wisdom attributed to baseball’s Yogi Berra: “Baseball is 90 per cent mental. The other half is physical.” As a former baseball player, I can attest to the importance of a strong mental component to the game. I just don’t get his math.

Since taking up golf about three years ago, I have also learned of the mental component to the game. I like what golfer Bobby Jones said: “In golf, the most important distance is the five inches between the ears.” A similar quote of Jones is, “The object of golf is to beat someone. Make sure that someone is not yourself.” Both speak clearly of a mental component to the game.

Is there a mental component to endurance sports like triathlon, duathlon, and aquabike?

That’s the question I explore in this post.

Our Mind Contributes to Physical Endurance

Dr, Samuele Marcora appears to be the foremost expert on the relationship between the mind and endurance sports performance. He is widely cited in articles and posts on mental toughness in endurance sports.

In Mental fatigue impairs physical performance in humans, Dr. Marcora and his colleagues documented the effect of mental fatigue on physical performance. They claimed that their research provided “experimental evidence that mental fatigue limits exercise tolerance in humans.” They also concluded that these limits came through a higher perceived difficulty, rather than physical effects related to the cardiovascular, respiratory and muscular functions.

In his article titled “Quitter”, Matt Fitzgerald, author of RUN: The Mind-Body Method of Running by Feel, writes of another of Marcora’s tests, this involving ten members of a university rugby team. Team members were told to ride at 90 percent of their personal VO2 max power until exhaustion. On average, they rode about 12 minutes at 242 watts. Then, after supposedly being exhausted, they were immediately told to ride as fast as possible for five seconds. Their average power was now 731 watts.

The researchers’ conclusion was that the mind in addition to the body dictates an athlete’s performance.

Mental Toughness Can Be Trained For Triathlon

The good news is that we can increase the mental component of endurance sports through our training. Following are two approaches I found while preparing this post.

Training With An Attitude

TriDot Head of Coach Development and senior triathlete, Kurt Madden told me, “I find it really intriguing that we spend so much time on the physical aspect of training. But the mind can work with you or against you.”

In an effort to incorporate the mental component in triathlon training, Kurt has identifed four factors he uses to help triathletes achieve amazing results, no matter their age or gender. These factors come from a combination of Kurt’s experience as a 45+ year ultra distance endurance athlete and his study of sports psychology.

• The “grit” factor

In Grit: The Power of Passion and Perseverance, Angela Duckworth develops the “hypothesis that what really drives success is not ‘genius’ but a unique combination of passion and long-term perseverance.” Some people can look at any challenge, embrace it, and push through related pain. This “grit” can come from early life experiences, such as a difficult family situation, or from a “learn it as you go” approach.

• Intention to be successful

Kurt has observed that “those people that do better mentally in longer events have the intention to be successful.” Those with this attitude not only believe they will be successful, but take action to ensure that they succeed.

“Intention” builds on enthusiasm, or positive attitudes, and on grit. Kurt encourages athletes with an intention to be successful to spot their “short term wins”. These wins confirm the success of their actions, producing the biochemical (hormonal) changes in our bodies that almost guarantee success.

• Willingness to be uncomfortable

While speaking with me for the post titled How To Slow Age-Related Drop in Running Performance, Kurt cited the tendency for older athletes to avoid being uncomfortable. However, to increase mental toughness, it is necessary to embrace some discomfort.

“When we are uncomfortable, there is a good thing that happens: we grow.”

Kurt has learned that one way to train our mind to embrace discomfort is to force ourself to go a little beyond where we think we need to stop. Relax, embrace the current discomfort, and go a little further.

• Staying “in the moment”

In introducing this factor, Kurt referred to The Mindful Athlete: Secrets to Pure Performance, a book written by George Mumford whom Michael Jordan credits “with transforming his on-court leadership of the [Chicago] Bulls.”

“Staying in the moment” avoids fretting about what has happened and forecasting too far ahead as to what could happen. Winning athletes include in their arsenal an ability to brush off mistakes or other failures and focus on doing what they know they are capable of.

Training While Mentally Fatigued

In “Brain Endurance Training Improves Dynamic Calisthenic Exercise and Benefits Novel Exercise”, published in the Journal of Strength and Conditioning Research, researchers Neil Dalloway et al, provide background on Brain Endurance Training (BET), at least partly based on Dr. Marcora’s research. The authors begin with the fundamental assumption that “perceived exertion is a limiting factor in endurance exercise.” By creating mental fatigue on top of the fatigue from physical training, the athlete adapts to performing under a higher level of fatigue and therefore a higher level of perceived exertion.

This allows the athlete to perform under stress, that is, conditions of mental fatigue. However, the real goal is for their endurance performance to be increased when the mental fatigue component is no longer present, such as on race day. According to the article’s authors, BET has been demonstrated to improve performance in cycling, running, and other activities requiring muscular endurance.

Cognitive Training Tools

Soma Technologies is a company which provides products following this approach. The company’s website says, “We Monitor Cognition, We Analyse Fatigue, We Optimize Performance.” The company also claims, “Soma has been proven to create psycho-physiological changes in the brain, enabling athletes to perform at higher levels with less perceived effort and make better decisions under fatigue.”

As I was preparing this post, I received an email from Soma, introducing their guide, “How to Design A Cognitive Training Plan.” This document is for coaches who want to incorporate mental toughness training into their athletes’ plan.

When reading through the guide, it surprised me to see the melding of mental (cognitive) and physical loading. For example, you may be aware of words such as periodization and progressive overload from triathlon training manuals. But did you know that there is a mental toughness equivalent to these? And, just as there are different components to comprehensive swim, bike, or run training programs, there are different components to cognitive endurance training.

What I Have Learned About Increasing Mental Toughness for Triathlon

It’s clear that there is a mental component to endurance sports, like triathlon, duathlon, and aquabike.

Those of you who know me, also know that I am an average triathlete having focused on sprint triathlons. I have not engaged specifically in mental endurance training because I have only recently learned about it. However, I relate to what I have heard and read about mental fatigue and mental toughness.

Over the years of triathlon training and racing, I believe I have sometimes struggled with the effects of mental fatigue, but also developed greater mental toughness.

For me, the quickest way to increase mental toughness has been being consistent in my training. Consistency builds confidence. When writing this, I was thinking of the triathlon swim.

I recall several races in which I became light-headed early in the swim, either through altitude or poor pacing. However, through plenty of pool and open water swims in different conditions, I had become confident in my ability to maintain calm and respond to the current situation without panicking. That’s a small example of mental toughness.

If you have been diagnosed with afib, is it worth training for multisport endurance competition, such as triathlon? This post, prompted by a reader diagnosed with afib, contains valuable advice from a cardiologist whose father is an ultramarathon runner.

Disclaimer

What is Afib?

Cardiologist Dr. Brian Saluck, Citrus Cardiology Consultants, P.A. describes atrial fibrillation (AF), or afib, as “a rapid heartbeat which is irregularly irregular. This means that the duration from beat to beat is different and the rhythm of the heart is not regular.”

He also noted three categories of AF:

• Rapid AF, for which the heart rate is above 110 beats per minute (bpm).
• Controlled AF for which the heart rate is between 60 and 110 bpm.
• Slow afib for which the heart rate under 60 bpm.

The irregular-irregularity common to all types makes afib a condition to be taken seriously. According to StopAfib.org, “If you have non-valvular afib, you are nearly five times more likely than someone without the condition to have a stroke; if you have valvular afib, your risk is 17 times higher. In fact, about 15% or more of all strokes in the US are related to afib. You also have twice the risk of dementia, three times the risk of heart failure, and a 40 to 90 percent increased risk of death compared with people your age who don’t have afib.”

What Are Risk Factors For Afib?

Several factors contribute to the risk of stroke or heart failure in patients with non-valvular atrial fibrillation (AF). These include the patient’s history with diabetes, hypertension, congestive heart failure, valve disease, and prior stroke or transient ischemic attack. Other factors include age, gender, and if the patient has sleep apnea.

Medical professionals often assign a number to each of the primary risk factors to arrive at a score called CHA2DS2-VASc. The risk score is used to define a treatment plan, including prescription of medications such as anti-coagulants.

Is endurance exercise a risk factor for producing an Afib event?

Is there such a thing as exercise-induced AF? “Yes, for some people, exercise can be a risk factor, ” according to Dr. Saluck.

“There is a thought that in athletes whose resting heart rate is too slow, exercise can induce an afib. A normal heartbeat, over 50 bpm, suppresses other irregular heart beats. However, if the sinus heart beat, that originating from the sinus node of the heart, is low, the irregular heartbeats can take over.”

Planning To Start Triathlon But Have Afib?

“The potential risk of exercising with AF is heart failure, ” stated Dr. Saluck. “As you demand more oxygen to the heart, the heart is not relaxing normally. When you are in afib, you lose the atrial kick that normally occurs when the top part of the heart, called the atrium, contracts during the peak filling of the ventricle. That extra little contraction improves the cardiac output by 15 to 20%.

“When you are not in a normal rhythm, that is in afib, you do not have the normal contraction of the sinus node. When the atrium does not contract, you lose the extra 15 to 20% efficiency. A person with afib can go into heart failure because of this.”

A person diagnosed with afib should check with their doctor before beginning triathlon training.

According to Dr. Saluck, “a patient with afib who is considering triathlon should have an electrocardiogram (EKG or ECG) and an echocardiogram, which is a sound wave picture of the heart. These will ensure that the structure of the heart is intact and that there are no valve problems with the heart which can cause the afib, such as a mitral valve regurgitation or aortic valve narrowing (stenosis), something older adults are more likely to exhibit.”

“A lot of times, afib is a marker for underlying ischemia or decreased blood flow to a heart artery. So, if the patient has risk factors in the family and has afib, I might want to do an exercise stress test by putting the patient on a treadmill to see how their endurance is and what their heart rhythm response is to exercise.”

“We also want to make sure their electrolyte levels are okay and check their thyroid to make sure it is not off.”

Depending on the patient, their initial results, and their history with endurance sports, including the distances and duration of the events, these tests may be repeated yearly or less frequently. “If everything with the initial tests is normal, the patient is probably good for five years.”

Managing Afib While Training For And Competing In Triathlon

Plenty of men and women diagnosed with AF take part in endurance sports, such as triathlon. Applying the advice of their primary physician or cardiologist means they can derive the benefits of exercise while minimizing the risks associated with the condition. Here is an approach for managing these risks.

Be Aware of Afib Related Signs and Triggers

While training or racing, listen to and look at your body for signs of AF. For example, are you feeling shortness of breath? Do you feel fatigued? Are legs becoming swollen? These could be warning signs of heart failure.

Not all the sports of triathlon may pose equal risk. A May 2023 publication in Clinical Journal of Sports Medicine reported an association between swimming and AF. In their paper titled AFLETES Study (Atrial Fibrillation in Veteran Athletes and the Risk of Stroke), authors Pallikadavath et. al. wrote, “This is the first study to demonstrate that swimming was associated with an increased risk of AF when compared with other sports and after adjusting for lifetime exercise dose.”

According to Dr. Saluck, this finding may be consistent with the ‘divers reflex’ phenomenon. The ‘divers reflex’, or mammalian diving reflex, is a common response of all mammals to entering cold water. One result is a drop in heart rate. This happens when, with swimming, a person first enters cold water. If the heart rate is already low, as is likely for trained athletes, the irregular heartbeats can take over.

While training, pay attention to your body and learn its response to the unique stress from each of the sports.

Monitor Heart Rate and Heart Rate Signature

According to ActiveCor, maker of KardiaMobile ECG sensor, “Pushing too hard is the number one reason why exercise may become unsafe for someone with atrial fibrillation.”

Technology for monitoring heart rate has been available for many years and is even more widely accessible today.

According to Dr. Saluck, pay attention to how rapidly your heart rate rises at the beginning of exercise and how quickly it comes down after exercise. Normally, heart rate should rise slowly over three to five minutes. Once exercise has ended, it should drop considerably over one to two minutes.

Recently, companies including Apple, Samsung, Fitbit, and Garmin have come out with wearable devices having an FDA cleared ECG (electrocardiogram) function. While not a watch or wearable device, ActiveCor’s KardiaMobile is a small sensor device that connects to your smartphone to record an ECG.   

Start Hydrated and Stay Hydrated

Hydration level is critical to heart function and a common thread in many of AF triggers. As we become dehydrated, our heart rate naturally increases. Dehydration also contributes to an imbalance in electrolytes, particularly magnesium and potassium.

There is also a high association between alcohol and AF, especially for those who drink more than mildly. In addition to weakening the heart muscle, alcohol is also a powerful diuretic, contributing to dehydration.

Restful Sleep

Sleep apnea not only affects the quality of sleep but can also increase AF events. “As we age, we lose muscle tone. This can extend to the muscles in the throat, increasing the risk of sleep apnea,” says Dr. Saluck.

Manage Anxiety

“Mental stress and anxiety definitely increase your risk for heart rhythm disturbances. Anxiety in particular can change the hormonal receptors of the heart.”

‘Broken heart syndrome‘ is a stress-related phenomenon which can also cause AF. Sudden acute but stressful events, such as loss of a loved one, being in a car accident, or dealing with financial problems may trigger ‘broken heart syndrome’.

Stress, whether physical, mental, or emotional, must be managed for us to perform at our peak athletically as well as to control AF.

Conclusion – Can I Do A Triathlon With Afib?

A diagnosis of AF does not automatically mean a person cannot begin or continue with multisport endurance activities like triathlon, duathlon, or aquabike. However, it is important to involve your doctor and/or a cardiologist in the initial and ongoing discussion.

Cardiologist Dr. Brian Saluck offers a few key recommendations. First, hydrate well before starting and then stay hydrated with electrolytes throughout the training session or race. He also recommends wearing a heart rate monitor to make sure their heart rate does not go too high outside its normal range. If your heart rate goes high or you don’t feel normal, take a break.
