Researchers examined the existing literature on how ultramarathon runners mentally respond to pain during races. They found that while runners' psychological approaches to pain have been somewhat documented, the actual relationship between these mental responses and race performance remains largely unstudied.

Researchers developed machine learning models to predict weekly injury risk in competitive endurance runners by analyzing multiple types of risk factors simultaneously. They tracked 142 runners for a full year, collecting data on genetics, training history, strength, movement patterns, body composition, nutrition, and weekly training loads to see how well computer algorithms could forecast when injuries might occur.

Researchers examined whether different types of resistance training could help middle-aged runners maintain the spring-like qualities of their calf muscles and Achilles tendons that typically decline with age. They compared three 10-week strength programs and measured changes in running efficiency, calf strength, and tendon stiffness.

Researchers investigated whether showing runners an evidence-based educational video about shoe selection would influence their actual purchasing choices. Despite providing scientific information about footwear, the educational intervention did not appear to change how participants selected their running shoes.

Researchers examined how fatigue from running affects the mechanics of how runners move, looking across multiple studies to identify consistent patterns. They found that as runners get tired, their movement patterns change in systematic ways that could create conditions associated with injury risk.

Researchers investigated whether video-based analysis of running movement patterns could reliably distinguish between runners with and without running-related injuries. The study explored how visible gait characteristics might correlate with injury status in running populations.

Researchers investigated how the social fitness app Strava influences motivation and goal-setting patterns in club runners who regularly use the platform. They found that while basic Strava features didn't directly correlate with motivational outcomes, runners who deleted training sessions due to perceived slow pace showed different goal orientations, and many participants actively modified their app usage to protect their motivation.

Researchers examined whether a simple single-leg hopping test could predict the forces and mechanics that masters runners generate during actual running, comparing those with and without Achilles tendon issues. The study explored potential connections between how runners perform in a controlled hopping assessment and their running movement patterns.

Researchers compared two methods for measuring hydration status in ultra-trail runners during a multi-day competition, examining whether simple urine test strips could match the accuracy of more sophisticated refractometry devices. They found strong agreement between the methods when assessing runners who maintained typical hydration levels expected of well-prepared ultra-endurance athletes.

Researchers documented how a 75-year-old runner with moderate hip osteoarthritis responded to a six-week physical therapy program combining manual therapy, supervised exercises, and home exercises. They tracked changes in pain, function, and running capacity as the runner prepared for a half-marathon goal.

Researchers compared how three different types of training—high-intensity intervals, fartlek, and steady continuous running—affected aerobic fitness, running mechanics, and heart rate recovery in sports science students over eight weeks. While all three approaches produced improvements, the structured high-intensity interval sessions generated the largest adaptations across physiological and biomechanical measures.

Researchers examined how prolonged endurance running, particularly marathons and ultramarathons, affects kidney function by reviewing evidence of temporary kidney stress markers that appear after races. They explored the various physiological mechanisms that contribute to this stress and the factors that might influence individual vulnerability to kidney injury during extended running efforts.

Researchers examined the oxygen demands and physiological characteristics of elite male distance runners when running at the pace required to complete a marathon in exactly two hours. This study provides specific data on how much oxygen the world's best runners need to sustain what represents the theoretical limit of human marathon performance.

Researchers examined how three different marathon racing shoes affected the biomechanics of competitive male runners during treadmill running. The study used a randomized crossover design to compare movement patterns and running mechanics across different footwear conditions in the same athletes.

Researchers examined whether ground reaction force measurements—the impacts recorded when your foot hits the ground—actually reflect the internal loading experienced by the tibia bone during running. They discovered that these commonly measured external forces don't correlate strongly with what's happening inside the bone across different running speeds and inclines.

Researchers examined whether teaching novice runners to modify their footfalls — specifically to land with less impact force — could reduce their likelihood of getting injured over a full year. They compared runners who received visual feedback to adjust their gait against those who trained similarly but without the feedback.

Researchers followed 300 recreational runners over two years to identify which baseline characteristics distinguished those who remained injury-free from those who developed overuse injuries. They measured everything from training history and biomechanics to psychological factors, then tracked who got injured and what predicted it.

Researchers developed a system using just three body-worn sensors to estimate ground reaction forces and knee joint angles during running. They trained artificial neural networks on data from eight runners to predict these biomechanical measurements that traditionally required laboratory-based force plates and motion capture systems.

Researchers examined how prototype running shoes affected the energy demands of running compared to standard footwear. They measured metabolic efficiency during running and used their findings to project potential performance implications for elite marathon runners.

Researchers examined whether marathon runners cluster their finishing times around psychologically meaningful round numbers like 4:00:00, suggesting these times function as mental reference points. Analysis of nearly 10 million marathon finishes revealed significant bunching of times just under major hour marks, indicating runners adjust their effort and pacing strategies to achieve these symbolic targets rather than simply running at consistent intensity throughout.

Researchers examined the relationship between high-speed running volumes and hamstring injuries in professional Australian Football League players over two seasons. They found that players who performed unusually high amounts of high-speed running relative to their own typical patterns faced substantially greater odds of hamstring injury in the following weeks.

Researchers examined the relationship between training workloads, high-intensity running exposure, and injury occurrence in elite Gaelic football players. They found that athletes maintaining higher chronic training loads and regular exposure to maximal velocity running experienced fewer injuries compared to those with lower workloads and less high-speed running exposure.

Researchers investigated whether running triggers the release of a specific protein called cathepsin B into the bloodstream and whether this protein relates to memory performance. They found that running appears to increase cathepsin B levels systemically, and this increase showed associations with better memory function in their participants.
