    My lab tested aet was at a heart rate of 127. Today I worked out and my heart rate was 140. I was totally comfortable , not breathing deeply and able to easily speak full sentences. Caveat it was 100 degrees Fahrenheit with a heat index of 107. Could my new aet be above 140 ? I have been working out several months since lab test . Or did heat skew the curve ? Respectfully asking for educated opinion .

    Heat will shift the curve. When it is hotter your heart will beat faster in order to help cool you off. AeT will be affected by a lot of factors, temperature, elevation, time of day, nutrition, etc. If you want to get a more accurate measure of AeT it would probably be best to perfrom a heart rate drift test on a track during “normal” summer weather, or you could just run based on effort for the time being.
