#Endurance

A wave of recent research suggests that structured, boundary-pushing workouts may cultivate mental toughness and, in turn, enhance performance under pressure. While the idea of “toughness” sounds almost like a character trait, scientists are increasingly treating it as something that can be trained through deliberately challenging physical activities. The latest evidence points to a modest but meaningful link between how people push through discomfort in training and how they perform when the stakes rise, particularly in endurance-based tasks that demand sustained effort over time. For Thai readers, these findings carry practical implications across military-style fitness programs, competitive sports, and everyday wellness routines where resilience is a valuable asset.

Across the world’s top endurance groups, a training approach called double-threshold training is gaining traction as a way to push performance beyond traditional limits. The core idea is simple in concept but demanding in practice: schedule two workouts each day that sit between the athlete’s first and second lactate thresholds, the point at which fatigue and lactate accumulation begin to accelerate. These sessions, spaced several hours apart, are designed to train the body to tolerate the “dull ache” of prolonged effort and to improve sustained power when racing at threshold intensity. In plain terms, athletes push through a higher ceiling without fully crossing into maximal effort, training the body to clear lactate more efficiently while extending the time before fatigue bites.

A new study raises important questions about the health effects of extreme endurance running, including potential precancerous changes in the colon. For Thailand’s growing running community, the findings call for careful interpretation and practical guidance from healthcare professionals.

In Thailand, running has become a beloved activity that blends fitness with charity and temple-based community events. Many families view long-distance running as a virtuous pursuit aligned with Buddhist values of caring for the body. The new findings therefore carry broad relevance for runners and their households, not just individual athletes.

A small new study found high rates of precancerous colon polyps in marathon and ultramarathon runners. The research raised questions about extreme exercise and early-onset colorectal risk (New York Times) (New York Times).

The finding matters because many Thais run for health and for charity. The result may change how doctors advise endurance athletes in Thailand.

An oncologist in Virginia recruited 100 runners aged 35 to 50 for colonoscopies. He saw almost half with polyps and 15 percent with advanced adenomas (New York Times).

A groundbreaking medical investigation has uncovered disturbing correlations between extreme endurance running and precancerous colon abnormalities, potentially transforming how physicians advise Thailand’s rapidly expanding marathon community. The research challenges decades of assumptions about exercise and cancer prevention, revealing that even activities traditionally considered purely beneficial may carry hidden health risks that demand immediate attention from Thai healthcare providers.

The study’s implications resonate powerfully throughout Thailand, where marathon participation has surged dramatically in recent years, with charitable running events becoming deeply embedded in temple culture and community fundraising traditions. Thai families increasingly encourage running as virtuous physical activity that aligns with Buddhist principles of caring for the body, making these unexpected findings particularly significant for a population that views distance running as inherently healthy and spiritually meaningful.

Hyrox is reshaping fitness competition worldwide, combining running with functional workouts in a format accessible to beginners and elite athletes alike. In Thailand, where Muay Thai gyms, running clubs, and group fitness are already vibrant, Hyrox offers a new, scalable model for public health, wellness tourism, and tactical training communities.

A Hyrox race features eight one-kilometer runs interspersed with stations such as sled pushes, wall balls, and burpee broad jumps. The standardized format lets participants compare results globally, from casual gym-goers to seasoned athletes. Across events, completion times average about 90 minutes, while top competitors are approaching the 60-minute mark, setting aspirational benchmarks for enthusiasts worldwide. Data from research and practitioner reports highlight Hyrox’s blend of endurance and strength, with running accounting for the majority of the workload.

The world of fitness racing is rapidly evolving, with the Hyrox competition emerging as a new global phenomenon that challenges athletes of all backgrounds in a unique blend of endurance and strength. Recent research and first-hand reports from elite competitors reveal how Hyrox is not only shaking up traditional sporting events but is also transforming training modalities for both everyday gym-goers and military professionals. As Thais increasingly embrace varied fitness pursuits, the Hyrox model—already surging in popularity across Europe and the US—offers accessible inspiration and potential for the Kingdom’s burgeoning wellness and tactical training communities.

A new wave of scientific insight has highlighted a dilemma familiar to every runner: when exhaustion sets in, is it your legs giving out first or your lungs and heart? The answer, experts say, could fundamentally alter the way athletes and casual joggers alike structure their training programs, and the latest research underscores the importance of accurately identifying the source of fatigue to improve running performance and overall health (Runner’s World).

A new wave of science helps untangle a familiar runner dilemma: when exhaustion hits, is it leg fatigue or cardiorespiratory fatigue? Experts say identifying the source can change how both serious athletes and casual joggers train for better performance and safer workouts. In Thailand, where running events and park runs are increasingly popular, this distinction is especially relevant for health, safety, and effective coaching.

Cardiorespiratory fatigue signals—breathlessness, a racing heart, and mental fog—often point to the cardiovascular system struggling to meet the oxygen needs of working muscles, even if the heart and lungs are not “weak.” The issue, researchers note, is how efficiently oxygen is delivered to and used by muscles. A leading exercise physiologist explains that mitochondria and tiny capillaries determine how well oxygen is utilized, not just how much is inhaled.

A recent study, highlighted in a feature by Men’s Journal, has found that distance runners can substantially extend their time to exhaustion—by as much as 32 percent—by implementing a specific post-workout recovery technique. This discovery, though focused on runners, carries significant implications for athletes and fitness enthusiasts across Thailand, where running continues to gain popularity as both a competitive sport and a healthy lifestyle pursuit.

In Thailand, where urban marathons and charity runs have become a staple in cities such as Bangkok and Chiang Mai, optimizing performance and recovery is a common goal among athletes and recreational runners alike. The new study, referenced in Men’s Journal’s report, provides compelling evidence supporting a post-exercise recovery “hack” that may help runners outpace their previous limits and enhance overall stamina.

A recent study highlighted by Men’s Journal suggests distance runners can extend their time to exhaustion by up to 32 percent with a specific post-workout recovery technique. While the finding centers on runners, it carries meaningful implications for athletes and fitness enthusiasts across Thailand, where long-distance running is rising in popularity as both sport and lifestyle.

In Thailand, urban marathons and charity runs are popular in Bangkok, Chiang Mai, and beyond. Optimizing performance and recovery is a common goal for both competitive runners and casual joggers. The Men’s Journal piece references research showing a scientifically backed recovery practice immediately after exercise that may help runners push past prior limits and improve stamina.

A recent study by researchers at the University of the Basque Country, published in Nature Metabolism, found that marathon running can temporarily reduce myelin content in the brain. Importantly, these changes are fully reversible within two months, offering reassurance to endurance athletes concerned about lasting neural effects.

As Bangkok’s marathon scene grows, this finding is particularly relevant for Thai runners who tackle the 42-kilometer challenge. The study introduces the concept of metabolic myelin plasticity, suggesting that during intense exercise the brain may tap myelin lipids as an additional energy source when glucose is scarce. This aligns with established knowledge that glycogen stores deplete during long efforts, prompting the body to adapt its energy pathways.

A small, cutting-edge study suggests the brain may temporarily convert its own myelin into fuel during extreme endurance events like marathons. This unexpected mechanism could help protect overall brain function when glucose supply drops during intense exercise.

Researchers in Spain followed 10 marathon runners, scanning their brains with MRI before and after the races. They found that 24 to 48 hours after finishing a grueling 42-kilometer run, myelin levels in key brain regions—those governing movement, coordination, sensation, and emotion—decreased noticeably. Importantly, these changes were not permanent. By two weeks post-race, myelin began to recover, and most participants returned to baseline within about two months.

A small pilot study suggests the brain may tap its own energy reserves during intense endurance efforts. Spanish researchers observed changes in brain white matter among marathon runners, hinting at a form of neuroplasticity that could help preserve function under extreme physical stress.

Researchers conducted MRI scans on ten endurance runners (eight men and two women) before and after a 42-kilometer race. The scans showed a measurable drop in myelin, the fat-rich sheath around nerve fibers that facilitates rapid signaling. The decrease was most evident in brain regions responsible for movement, balance, sensory processing, and emotion. Notably, myelin levels began to recover within 24 to 48 hours after the race and largely returned to baseline within two months for the six participants who had follow-up scans.
