Researchers have discovered that lower cholesterol levels can reduce muscle gain from exercising.
The team studied 55 men and women, ages 60-69. Three days a week for 12 weeks, they performed several exercises, including stretching, stationary bike riding and vigorous weight lifting.
The researchers found a significant association between dietary cholesterol and change in strength. 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. Subjects who were taking cholesterol-lowering drugs also showed lower muscle gain.
The lead researcher added, “We were not expecting to get these kind of results.”
