 Muscular Fitness More Important Than Body Weight To Prevent Heart Disease

WRITTEN BY MONICA MOLLICA ON 03 NOVEMBER 2013.

Exercise protects against heart disease in many ways. One important mechanism is by elevating HDL, a.k.a. the “good” cholesterol.[1] It is well established that high levels of HDL are protective against cardiovascular disease and the National Cholesterol Education Program (NCEP) has emphasized increasing HDL levels to help reduce CHD risk. [2-4]  However, not only HDL levels are important. Emerging research in showing that HDL quality and function is as important, if not more important for health promotion and prevention of cardiovascular and metabolic diseases...[5-7]

Researchers from the University of California/Los Angeles (UCLA, California, USA) investigated HDL quality in three groups of young men:[8]


1) overweight untrained (BMI 30 - no training)

2) overweight trained  (BMI 29 - 4 d or more per week resistance training)

3) lean trained (BMI 24 - 4 d or more per week resistance training)

It was found that HDL function was significantly better in both trained groups compared with the overweight untrained group. However, HDL function in the overweight trained group was not significantly different from that of the lean trained group. 

Thus, muscular fitness is more important than body weight for HDL functionality and could be a potential mechanism by which resistance training may decrease cardiovascular disease risk.

Interestingly, it was noted that some metabolic and hormonal parameters were related to HDL functionality. High HDL function not only correlated with lower oxidized LDL, which is implicated in atherosclerosis, but also with higher testosterone levels. The latter can explain why low testosterone levels are associated with increased cardiovascular disease risk.[2-5]

High HDL function not only correlated with lower oxidized LDL, which is implicated in atherosclerosis, but also with higher testosterone levels. The latter can explain why low testosterone levels are associated with increased cardiovascular disease risk.[9-12]

This is the first study to demonstrate a relationship between HDL redox activity (an aspect of HDL function) and testosterone.

Comments:  Monica's article explains that exercise helps prevent cardiovascular problems and an exercise program of strength training offers the trainee results that will show up in your blood tests!  Loss of fat because of poor eating habits, and little or no exercise leads to poor health.  Get to the gym ASAP!  Ellen DeGeneres says this about the gym: "I'm so unfamiliar with the gym, I call it James".
