Summary
Swimming performance is not affected by skin temperature changes during transition periods longer than 10 minutes. Longer rest after warm-up does not significantly alter skin temperature or swimming outcomes.
Area of Science:
- Sports Science
- Exercise Physiology
- Human Performance
Background:
- Core, muscle, and skin temperature changes during warm-up to competition transitions can impact athletic performance.
- Understanding these thermal dynamics is crucial for optimizing athletic readiness.
Purpose of the Study:
- To evaluate skin temperature changes during varying transition phase durations (10, 20, 45 minutes) before a 100m front crawl swim.
- To determine the relationship between pre-exercise skin temperature and swimming performance metrics.
Main Methods:
- Nine adolescent male swimmers underwent standardized warm-ups followed by three maximal 100m front crawl trials after randomized 10, 20, and 45-minute transition periods.
- Measurements included skin temperature, swim times, stroke characteristics, heart rate, lactate levels, and perceived exertion.
Main Results:
- Skin temperature increased logarithmically over time, with no significant differences after 15 minutes.
- Swimming performance and psychophysiological variables remained consistent across all transition durations.
- Lower skin temperature was observed after the 10-minute transition compared to 20 and 45 minutes.
- No significant correlation was found between pre-exercise skin temperature and 100m swim performance.
Conclusions:
- Transition periods exceeding 10 minutes do not lead to further significant thermal changes in swimmers.
- Within the physiological parameters investigated, pre-exercise skin temperature does not appear to be a critical determinant of swimming performance.

3.5K
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...

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...
