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.
Needless to say, these findings caught us totally off guard, he explains.
From here, we need to look at a number of questions, such as what exactly happens to cholesterol while you are exercising? What role does protein intake have in all of this? What we really need to do is to trace cholesterol the moment it goes into the muscles.
Combined with exercise, cholesterol appears to play a role in contributing to muscle gain, Riechman says. The key here is working out it doesnt mean sitting in front of a television all day thinking you dont have to worry about cholesterol levels.
Our findings show that the restricting of cholesterol while in the process of exercising appears to affect building muscle mass in a negative manner. If its true, as our findings suggest, that cholesterol may play a key role in muscle repair, we need to know exactly how that happens. And because cholesterol is negatively associated with cardiovascular health, we need further study in this area. It shows that there is still a lot about cholesterol that we dont know.
