Physical Activity Level (PAL) is strongly influenced by genetic predisposition, with 72-78% of the variance in activity levels within a controlled environment attributed to genetic factors.
Accept that your natural tendency to be active or sedentary is largely genetic. This doesn't mean you can't change, but it means you might need to rely more on structure and habit formation than on 'natural' motivation. Don't compare your baseline activity to others who may have a different genetic predisposition.
The calculated contribution of genetic factors to the variance in physical activity was 72–78% (Joosen et al., 2005). Thus, a large part of the variation in physical activity between subjects can be ascribed to predisposition.
Why this rating
Based on twin studies using doubly labeled water validated accelerometers, providing strong causal inference for genetic contribution.

More from this paper
- Exercise training increases physical activity level (PAL) in young adults only when energy intake is increased to maintain energy balance; otherwise, compensatory reductions in non-exercise activity negate the total energy expenditure increase.Good
- Higher body weight does not necessarily result in a lower Physical Activity Level (PAL); obese individuals often have similar or higher activity-induced energy expenditure (AEE) than lean individuals due to higher movement costs, despite moving less frequently.Good
