Solid rebuttal. Thank you for educating me.Originally Posted by TrailRunAZ
Apparently not in the Canadian world. Not sure why you decided to harp in with that comment, was just trying to be helpful and supportive to OP.
Effects of Endurance Exercise Training on Plasma HDL Cholesterol Levels Depend on Levels of Triglycerides | Arteriosclerosis, Thrombosis, and Vascular Biology (really shows a relation between HDL and TG levels in exercise model, but states in intro the known relationship between HDL levels and exercise).
There were a number of other studies, one notable one in Japan that was a metanalysis and which showed moderate elevations of HDL with exercise. It inferred that it was duration and not intensity which may have the effect. This anecdotally coincides with my personal HDL level of 70 when running 60-90 min trail runs daily.
I don't have link for Japanese study, but a few others:

Recent research shows the relationship may be due to an enzyme activity induced by exercise.
