Researchers at Texas A&M University have discovered that lower cholesterol levels can actually reduce muscle gain with exercising. ...

The team studied 55 men and women, ages 60-69, who were healthy non-smokers and were able to perform exercise testing and training.

Three days a week for 12 weeks, participants performed several exercises, including stretching, stationary bike riding and vigorous weight lifting. Those who had to miss one or more sessions all conducted make-up sessions so that by the study's end, the entire group had engaged in uniform activities. Also, all participants consumed similar meals.

At the conclusion of the study, the researchers found that there was a significant association of dietary cholesterol and change in strength. In general, those with higher cholesterol intake also had the highest muscle strength gain.

Cholesterol circulating in the blood also appeared to have contributed to greater muscle gain in the participants, Riechman said.

"As you exercise, your muscles can become sore because they are rebuilding muscle mass. More cholesterol may result in a more robust inflammatory response. We know that inflammation in some areas, such as near the heart, is not good, but for building muscles it may be beneficial, and cholesterol appears to aid in this process."

Riechman said that subjects who were taking cholesterol-lowering drugs while participating in the study showed lower muscle gain totals than those who were not.
