Heating and Cooling Curves02:44

Heating and Cooling Curves

27.8K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Specific Heat01:16

Specific Heat

67.4K
The specific heat capacity of a substance refers to the energy required to increase the temperature of one gram of that substance by one degree Celcius. Specific heat capacity is often represented in calories (cal), grams (g), and degrees Celsius (oC), but can also be expressed in joules (J), kilograms (kg), and Kelvin (K), among other units.
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or...

Heat Flow and Specific Heat01:12

Heat Flow and Specific Heat

6.8K
Heat is a type of energy transfer that is caused by a temperature difference, and it can change the temperature of an object. Since heat is a form of energy, its SI unit is the joule (J). Another common unit of energy often used for heat is the calorie (cal), which is defined as the energy needed to change the temperature of 1 g of water by 1 °C, specifically between 14.5 °C and 15.5 °C, since the energy needed shows a slight temperature dependence. Another commonly used unit is...

Quantifying Heat02:46

Quantifying Heat

62.1K
Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the...

Exercise Stress Test01:26

Exercise Stress Test

1.3K
Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Exercise and Muscle Performance01:27

Exercise and Muscle Performance

2.4K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Summary

Wearing a cooling vest during intense exercise in heat reduced physiological strain and perceived exertion. However, peak sprint performance remained unaffected by the cooling intervention.

Area of Science:

  • Sports Science
  • Exercise Physiology
  • Environmental Heat Stress

Background:

  • Torso cooling via vests can enhance exercise performance in heat.
  • Its impact on intermittent exercise performance in heat is not well-documented.

Purpose of the Study:

  • To assess torso cooling effects on sprint performance during intermittent exercise in heat (35°C, 50% RH).
  • To evaluate physiological and perceptual responses to torso cooling during such exercise.

Main Methods:

  • A crossover study design was employed.
  • Ten non-heat-acclimated male soccer players participated.
  • Participants underwent two 90-minute intermittent running sessions in heat, one with a cooling vest and one without.

Main Results:

  • Peak sprint speed was not significantly improved by the cooling vest.
  • During the second 45-minute period, rectal temperature, its rate of rise, skin temperature, perceived exertion, and thermal sensation were lower with the cooling vest.
  • Heart rate was not affected by the cooling vest.

Conclusions:

  • Torso cooling with a vest during intermittent exercise in heat lowers physiological and perceptual strain.
  • Cooling vests do not enhance peak sprint speed in this context.
