Natural sporting ability and predisposition to cardiovascular disorders

摘要

We tested the hypotheses that people with a natural ability in 'power sports' (a presumed marker for predominance of type 2, glycolytic muscle fibres) might have increased risks of coronary heart disease (CHD) compared to those with a natural ability in 'endurance sports' (as a marker for predominance of type 1, oxidative muscle fibres). We examined subsequent cardiovascular disorders retrospectively in 231 male former soldiers, aged 34-87 years, who had undergone a course in physical training in the Army School of Physical Training, Aldershot, UK, who assessed themselves as having natural ability in either power (n=107) or endurance (n=124) sports.
