In a second analysis, the researchers divided participants into four groups based on peak physical activity time - midday, early morning (8 a.m.), late morning (10 a.m.), and evening (7 p.m.).
After adjusting for age and gender, participants who were most active in the early or late morning had 11 per cent and 16 per cent lower risks of incident coronary artery disease, respectively, compared to the reference group, the study added.
"Our findings add to the evidence on the health benefits of being physically active by suggesting that morning activity, and especially late morning, maybe the most advantageous," said Albalak.
