Staying Fit Slows Decline in Maximal Heart Rate With Aging Process

Cardiovascular disease remains the number one cause of death. It is well known that being physically fit is associated with lower risk of disease.

One factor associated with higher risk of cardiovascular disease is having a low maximal heart rate. Although maximal heart rate inevitably declines with age, there is still a lot of debate on whether fitness can slow this aging response.

Arsenic in Drinking Water Increases Cardiovascular Disease Risk
High levels of arsenic exposure (>500 µg/L) in drinking water have been related to increased risks to cardiovascular diseases.

‘The maximal heart rate among physically fit people was observed to decline at a slower rate with age compared to low fit participants.’

In this large scale study, 3,318 healthy men and women performed a maximal exercise test and some of these subjects (643 men and women) were tested repeatedly over many years.

The investigators compared the decline in maximal heart rate with age among high, moderate, and low fit groups. The results showed that higher fit participants' maximal heart rate declined at a slower rate with age compared to low fit participants.

This research provided compelling evidence that staying fit slows this aspect of the aging process.

Severe Psoriasis May Increase Risk of Cardiovascular Disease
The severity of psoriasis, a skin condition, is linked to the amount of inflammation in the blood vessels that increases the risk of heart disease.
