Summary
Running performance differs between treadmill and indoor track 10-km time trials. Indoor track runs were slower, suggesting pacing or metabolic cost variations influence self-paced running performance.
Area of Science:
- Exercise Physiology
- Sports Science
- Human Performance
Background:
- Self-paced time trials are standard for assessing running performance.
- Understanding environmental influences on performance is crucial for accurate assessment.
Purpose of the Study:
- To investigate physiological and thermoregulatory differences between treadmill and indoor track running.
- To determine if these differences impact 10-km self-paced time trial performance.
Main Methods:
- Ten recreationally trained male runners completed 10-km time trials on a treadmill (1% grade) and an indoor track.
- Physiological data (core/skin temperature, heart rate) were continuously monitored.
- Trials were randomized and counterbalanced.
Main Results:
- 10-km run time was significantly longer on the indoor track (41.66 min) versus the treadmill (40.10 min).
- No significant differences were observed in heart rate or core body temperature.
- Skin temperature was higher during the treadmill trial.
Conclusions:
- Performance in a 10-km self-paced time trial is affected by the running environment (treadmill vs. indoor track).
- Pacing strategies or metabolic cost variations may explain the observed performance differences.

01:26Thermoregulation
2.8K
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

01:25Body Temperature
3.7K
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...

2.1K
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

01:09Thermal Stress
2.5K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...

01:21Masonry in Cold and Hot Weather Conditions
416
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

01:17Increased pulse rate
1.5K
Tachycardia is a condition marked by an abnormally fast or irregular heart rate, surpassing the typical resting rate. In adults, tachycardia is characterized by a pulse rate ranging from 100 to 180 beats per minute. The increased heart rate can result in inadequate blood flow to various body parts, ultimately diminishing the oxygen supply to organs and tissues.
Many factors can elevate the risk of developing tachycardia. These include advanced age, a family history of arrhythmias, and an...
