Summary
Intermittent palm cooling, especially with gloves, significantly improved rowing performance by reducing physiological fatigue markers like heart rate and blood lactate. This method enhances work capacity during ergometry workouts.
Area of Science:
- Sports Science
- Exercise Physiology
- Human Performance
Background:
- Optimizing athletic performance requires understanding environmental and physiological factors.
- Intermittent palm cooling is a potential strategy to mitigate heat strain and improve endurance.
Purpose of the Study:
- To investigate the impact of intermittent palm cooling, with and without gloves, on rowing ergometry performance.
- To assess physiological responses and performance metrics during rowing with different palm cooling protocols.
Main Methods:
- Thirty-four subjects completed three rowing ergometer workouts under three conditions: no palm cooling, cooling during exercise, and cooling during and post-exercise.
- Physiological data (heart rate, blood lactate) and performance (distance rowed) were collected and analyzed.
- Palm cooling involved intermittent cold application (8.1° C) for 10 or 20 minutes.
Main Results:
- Subjects who received intermittent palm cooling (PCex, PCex&post) rowed significantly farther than those with no cooling (NoPC).
- Heart rate and blood lactate concentrations were significantly lower in the palm cooling groups compared to the no cooling group.
- Palm cooling reduced physiological markers of fatigue, enabling greater work output.
Conclusions:
- Intermittent palm cooling, particularly when administered with gloves, enhances rowing performance by reducing fatigue.
- This cooling strategy can increase work capacity and improve physiological markers during intense exercise.
- Further research should explore optimal cooling parameters for heat dissipation and performance enhancement.

01:09Thermal Stress
3.1K
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...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

01:26Thermoregulation
1.8K
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,...

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,...

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
