In the case of trained cyclists with an average age of 66, garments actually increased body temperature and in some cases increased heart rate after an intense effort.
I thought it was normal for the heart rate to increase after physical effort?
Regardless of what one is wearing, body temperature is going to rise after exercise.
I think either the wording of the study is wrong or it is a load of tosh.
Mr Leoz said that older people should not use heat-dissipating compression clothing, because it could increase the onset of hyperthermia - the raising of body temperature above the normal levels.
Which is what I would expect after cycling a good distance.
