Abstract

Background: Physical activity and exercise training are associated with a lower risk for coronary events. However, cross-sectional studies in middle-aged and older male athletes revealed increased coronary artery calcification (CAC) and atherosclerotic plaques, which were related to the amount and intensity of lifelong exercise. We examined the longitudinal relationship between exercise training characteristics and coronary atherosclerosis. Methods: Middle-aged and older men from the MARC-1 (Measuring Athlete’s Risk of Cardiovascular Events 1) study were invited for follow-up in MARC-2 (Measuring Athlete’s Risk of Cardiovascular Events 2) study. The prevalence and severity of CAC and plaques were determined by coronary computed tomography angiography. The volume (metabolic equivalent of task [MET] hours/week) and intensity (moderate [3 to 6 MET hours/week]; vigorous [6 to 9 MET hours/week]; and very vigorous [≥9 MET hours/week]) of exercise training were quantified during follow-up. Linear and logistic regression analyses were performed to determine the association between exercise volume/intensity and markers of coronary atherosclerosis. Results: We included 289 (age, 54 [50 to 60] years [median (Q1 to Q3)]) of the original 318 MARC-1 participants with a follow-up of 6.3±0.5 years (mean±SD). Participants exercised for 41 (25 to 57) MET hours/week during follow-up, of which 0% (0 to 19%) was at moderate intensity, 44% (0 to 84%) was at vigorous intensity, and 34% (0 to 80%) was at very vigorous intensity. Prevalence of CAC and the median CAC score increased from 52% to 71% and 1 (0 to 32) to 31 (0 to 132), respectively. Exercise volume during follow-up was not associated with changes in CAC or plaque. Vigorous intensity exercise (per 10% increase) was associated with a lesser increase in CAC score (β, −0.05 [−0.09 to −0.01]; P =0.02), whereas very vigorous intensity exercise was associated with a greater increase in CAC score (β, 0.05 [0.01 to 0.09] per 10%; P =0.01). Very vigorous exercise was also associated with increased odds of dichotomized plaque progression (adjusted odds ratio [aOR], 1.09 [1.01 to 1.18] per 10%; aOR, 2.04 [0.93 to 4.15] for highest versus lowest very vigorous intensity tertiles, respectively), and specifically with increased calcified plaques (aOR, 1.07 [1.00 to 1.15] per 10%; aOR, 2.09 [1.09 to 4.00] for highest versus lowest tertile, respectively). Conclusions: Exercise intensity but not volume was associated with progression of coronary atherosclerosis during 6-year follow-up. It is intriguing that very vigorous intensity exercise was associated with greater CAC and calcified plaque progression, whereas vigorous intensity exercise was associated with less CAC progression.

  • Previous studies examining the link between training characteristics and CAD have yielded conflicting results, probably resulting from differences in training load definitions and measurement approaches.

    The Exercise Volume section (page unavailable) describes differing findings across studies: MARC-2 found no association with progression, while a Korean population study found greater CAC progression in a more active group. It also describes different activity categories and suggests that follow-up duration may matter, but it does not say that differences in training-load definitions and measurement approaches probably caused the conflicting results.

  • Aengevaeren et al defined "very vigorous" exercise intensity as >9 METs, a threshold commonly exceeded by endurance athletes and insufficient to distinguish training extremes in this population.

    From Wearable-Derived Training Load and Coronary Atherosclerosis in Middle-Aged and Older Athletes and Physically Active Controls: A New Perspective From the Master@Heart Study (2026) · cites this paper as [14]

    The methods passage (page unavailable) defines very vigorous exercise as ≥9 METs, not strictly >9 METs. The Results report a median of 34% of exercise volume at that intensity among participants, but the paper does not say the threshold is commonly exceeded by endurance athletes generally or that it is insufficient to distinguish training extremes. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Aengevaeren et al later reported a relationship between high-intensity exercise, rather than exercise volume, with CAD progression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
