Does Q10 offer strength athletes cardiac protection?
Athletes who do strength sports develop an enlarged heart. This is not a problem in itself, but when combined with anabolic substances this enlargement can result in a fatal abnormality. Taking a Q10 co-enzyme supplement may offer protection, if the results of studies published by American cardiologists in the 1990s are anything to go by.
Cardiologists observe this phenomenon primarily in people with high blood pressure, but occasionally chemical strength athletes also develop a dangerous form of left ventricular hypertrophy.
According to a 2003 Finnish study, it's steroids users who also make long-term use of growth hormone that should be worried. [Int J Sports Med 2003; 24: 337-343.] The amount of blood that the heart is capable of pumping round the body can reach dangerously low levels in this group.
Left ventricular hypertrophy is believed to be caused by heart cells becoming chronically fatigued. Langsjoen reasoned that heart cell vitality could be restored through supplementation aimed at reducing the negative effects of left ventricular hypertrophy.
EF slope, LVEDD and FS are cardiological variables which indicate how well the heart is pumping blood. The results show an improvement, but it's not statistically significant. Nevertheless, the patients had less chest pain, were less tired and less short of breath.
In 1999 Australian cardiologists published the results of a study which showed that Q10 supplementation had no effect on the left ventricle of patients. [J Am Coll Cardiol. 1999 May; 33(6): 1549-52.] They used a lower dose than the Americans.
