Researchers from Cambridge University published a meta-analysis in
PLOS ONETrusted Source identifying 13 candidate genes associated with fitness outcomes in previously
untrained people.
- Genetic influences accounted for 72% of the difference in the results of
those in the strength training group.
- Genetic factors had less effect on the outcomes in the aerobic (44%) and
anaerobic power groups (10%).
- Further research is necessary to determine the exact roles of fitness genes
and how best to tailor exercise training according to genetic makeup.
Physical activity is
essentialTrusted Source for maintaining health, reducing chronic diseases, and preventing premature
death. The
2018 physical activity guidelines for AmericansTrusted Source recommend a combination of moderate intensity and vigorous intensity aerobic
exercise alongside muscle-strengthening activities involving the major
muscle groups.
The
adviceTrusted Source is for adults to do 150–300 minutes of moderate intensity aerobic
activity, 75–150 minutes of vigorous intensity aerobic activity,
or an equivalent mix. They can spread this activity throughout the week
and should also engage in strength training on at least 2 days of the
week to reap additional health benefits.
