I do not have any research to offer but a few personal observations:
I recently had a good number of new clients all of whom told me that they had been doing HIIT training or kickboxing. What they had in common was that they did not get that sense of well-being which should be the result of exercise. Instead they had aches and pains and were wondering whether this was the best form of exercise for them.
The results of my assessments were that they lacked the structural stability necessary for this high-intensity form of exercise.
That does not mean that HIIT training and kickboxing are inherently dangerous if done by a person whose body is ready for them. I have my doubts, though, whether a proper assessment is made before people are admitted into the classes.
Hello Ashley Maginnis (Lickteig),
Are people exercising in the heat or do you mean new up and coming exercise? HIIT and kickboxing can be great forms of exercise when done properly and taught properly by an instructor who knows how to progress and regress the moves to the individual. This goes for any and all exercise formats: make it safe for the client and keep your eye on them to be sure everyone is safe.

While I do not have any research for you, I used to teach a kickboxing class that immediately followed a heated yoga class. Since the classes were back to back, there was little time for the temperature to adjust until we were fully into the kickboxing class. It did affect the intensity of my class (I had to make it less intense) as I felt the heat made it unsafe for myself and the participants.
There are problems associated with exercising in the heat, and there were definitely times that I felt nauseated during the class. In addition, I did not recover as quickly as when the temperature was normal from the beginning.
Heated HIIT or kickboxing is not worth the risk, and my question to those who are marketing a class like this is WHY?
