Harvard scientists recently conducted a study in which they learned that vigorous exercise raises the levels of vitamin D in a persons body.
Scientists stated “vigorous activity” as running, jogging, playing basketball or soccer and other similar sports for at least three hours per week significantly raise vitiman D levels.
According to the study exercising reduced the risk of heart attack by 22% by creating higher levels of good cholesterol and vitamin D.
According to Andrea Chomistek, a researcher at the Harvard School of Public Health:
“The fact that vitamin D plays a role in the relationship between exercise and risk of heart disease is a new finding.” Chomistek went on to add, “This likely comes from being outside more. People who exercise tend to be out in the sun, which raises their vitamin D level. I don’t think you’d get the same increase in vitamin D by staying inside and running on the treadmill.”
USA Today revealed that:
Chomistek and colleagues analyzed the activity levels and the blood work of men in the Health Professionals Follow-Up Study. During 10 years of follow-up, 412 men had a heart attack and were matched to a control group of 827 men who did not have heart disease.
The groups findings reported in the October issue of Medicine & Science in Sports & Exercise found that vigorous exercise helped raises HDL levels (good cholesterol) which accounts for 38% of the decreased risk of heart disease, while higher levels of vitamin D and lower levels of hemoglobin A1c (a marker of diabetes risk), apolipoprotein B (a blood protein) than those who were inactive.
While not directly studied researchers believe that people who exercise outside in the sun likely have higher levels of vitamin D than indoor exercisers.
