Final answer:
Cultural competence is not a barrier that limits participation in regular physical activity; instead, it involves understanding different cultures and would not prevent someone from exercising.
Step-by-step explanation:
All of the following are barriers that serve to limit participation in regular physical activity except: cultural competence. This option is not typically considered a barrier to physical activity. Instead, barriers often include lack of facilities, lack of motivation, and time constraints.
Cultural competence, on the other hand, generally refers to an individual's ability to understand, appreciate, and interact with people from cultures or belief systems different from one's own, and does not inherently limit one's ability to engage in physical activity.
