Factors Associated With Performance Decrements in Elite Athletes During Exercise Under Hot and Humid Ambient Conditions

Key Points

• To determine factors associated with performance decrements in elite athletes exercising in hot and humid conditions.
• Analyzed variables related to exercise responses, athlete characteristics, and thermoregulatory responses.
• Used multivariable regression modeling to assess the impact of these factors on performance.
• Measured heart rate, dehydration levels, body mass index, and thermal discomfort characteristics.
• Identified key factors affecting performance, such as heart rate and dehydration.
• Found that these variables accounted for 58% of performance decrements during exercise in the heat.
