Summary
Individuals with amputations may experience higher core body temperatures during running due to altered physiology. This case study found a runner with amputation had a higher maximum core temperature than a runner without amputation during a 10-mile race.
Area of Science:
- Exercise Physiology
- Sports Medicine
- Biomechanics
Background:
- Individuals with amputations may have altered thermoregulation due to decreased body surface area and increased energy demands for ambulation.
- This could potentially increase heat production and the risk of heat injury during physical activity.
Purpose of the Study:
- To compare core body temperature differences between individuals with and without amputations during a 10-mile run.
- To investigate the physiological responses to exercise in amputee runners.
Main Methods:
- A case study involving two runners, one with and one without amputation, completing a 10-mile road race.
- Collection of anthropometric data, body composition, and energy expenditure pre-run.
- Continuous monitoring of core temperature and activity levels during the race.
Main Results:
- The runner with amputation reached a maximum core temperature of 38.4°C, while the runner without amputation reached 37.9°C.
- Despite the higher core temperature, the runner with amputation completed the race at a slower pace, suggesting a lower thermal tolerance at similar exercise intensities.
Conclusions:
- Individuals with amputations may achieve higher core body temperatures at similar exercise workloads compared to non-amputees.
- Further research is warranted to fully understand thermoregulatory differences and heat injury risks in amputee athletes.

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:25Body Temperature
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...
01:07Body Temperature
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C (97–99°F), remaining relatively stable...
