Task: Answer Verification
Input (English): Question: Does contrast therapy cause fluctuations in human gastrocnemius intramuscular temperature?
Answer: Contrast therapy did not lead to significant fluctuations in muscle tissue temperature at 4 cm below the skin's surface. Therefore, it seems unlikely that the physiologic effects attributed to these fluctuations occur. A 1-minute exposure to a cold whirlpool during a typical contrast treatment does not appear to be long enough to significantly decrease tissue temperature after exposure to the warm hydrotherapy environment.
Output (English): no
