Spanish researchers at the Pablo de Olavide University in Sevilla hypothesized that the effect of physical activity on plasma Coenzyme Q10 levels and on plasma Coenzyme Q10/cholesterol ratios might vary according to the age of the individuals engaging in the physical activity. Their results show, for the first time, an apparently different effect of exercise on young people and on older people.
- Lower levels of plasma Coenzyme Q10 and lower Coenzyme Q10/cholesterol ratios were associated with high levels of physical activity in the young people more so than in older people who were also exercising. That result was surprising.
- Moreover, lower levels of plasma Coenzyme Q10 and lower Coenzyme Q10/cholesterol ratios were associated with high levels of physical activity in the younger people more so than with moderate levels of physical activity in younger people. That result was not surprising.
- What was most surprising was the data that showed that older people who exercised more often and more intensely had higher levels of Coenzyme Q10 in plasma and higher ratios of Coenzyme Q10 to cholesterol in plasma than did older adults who exercised moderately or who were mostly sedentary. In this respect, the effect of exercise on the older people differed from the effect of exercise on the younger participants [Del Pozo-Cruz 2014].
Coenzyme Q10 and physical activity in young people
In the Spanish study, the young participants had an average age of 20 years plus or minus 2 years. Two possible explanations come to mind for the lower plasma Coenzyme Q10 levels in highly active younger people:
