Factors Associated With Collapse During and After Ultramarathon Footraces: A Preliminary Study
The Physician and Sportsmedicine
|July 13, 2016
Summary
Ultramarathon runners who collapsed often had inadequate training, poor nutrition, or illness. Proper preparation is crucial for all runners to prevent exhaustion and collapse during extreme races.
Area of Science:
- Sports Medicine
- Exercise Physiology
- Endurance Sports
Background:
- Ultramarathon running presents unique physiological demands.
- Runner collapse during or after ultramarathons is a concern requiring investigation.
- Understanding contributing factors is key to preventing adverse events.
Purpose of the Study:
- To identify potential causes of collapse in ultramarathon runners.
- To compare training and preparation methods of collapsed runners versus controls.
- To inform strategies for improving runner safety in endurance events.
Main Methods:
- A preliminary study involving 48 collapsed ultramarathon runners.
- Questionnaires on training methods administered to collapsed runners.
- Comparison of training profiles with matched control runners who completed the race.
- Analysis of factors such as training, nutrition, and environmental conditions.
Main Results:
- Collapsed runners showed inadequate training more frequently.
- Insufficient carbohydrate loading and lack of a prerace breakfast were noted.
- Prerace illness and hypothermia (in cold conditions) were identified as factors.
- These factors were more prevalent in collapsed runners compared to controls.
Conclusions:
- Inadequate training and preparation are significant risk factors for ultramarathon collapse.
- Nutritional strategies like carbohydrate loading and prerace meals are important.
- Environmental factors such as hypothermia can contribute to collapse.
- Runner safety in ultramarathons depends heavily on thorough prerace preparation.

01:28Factors Affecting Creep
506
In normal-weight aggregate concrete, the hardened cement paste is the primary contributor to creep, whereas the aggregates, being stiffer than the cement paste, are more resilient to stress-induced deformation. The stiffness of the aggregates is defined by their modulus of elasticity, and the more voluminous they are in the concrete, the less it will creep.
Further, the water/cement ratio is critical, as a lower ratio increases concrete strength, thus reducing creep. The strength of the...

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:24Muscle Recovery and Fatigue
4.7K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
603
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

01:30Peripheral Artery Disease I: Introduction
568
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
