A new, counterintuitive research came out pointing toward high intensity exercise creating more calcification than lower intensity in males 45 +. Lower intensity exercise with increased volume did not have this effect.
“Exercise intensity, but not volume, was correlated with the progression of coronary atherosclerosis. The impact of vigorous exercise was found to be less effective in CAC progression; however, very vigorous exercise was associated with a more significant progression of CAC and plaque (calcified). This finding is in line with cross-sectional MARC-1 observation that revealed specific exercise intensities rapidly enhance the development of calcified plaque.”
