Which policy types can help improve community physical activity levels?

Policies that encompass formal written codes and social norms are crucial in improving community physical activity levels because they create a structured approach to promoting health and wellness. These policies often include measures like zoning laws that establish safe walking and biking routes, policies that mandate physical activity in schools, and community programs that incentivize active transportation. By establishing clear guidelines and expectations within a community, these formal written codes can effectively influence behavior and encourage a culture that prioritizes physical activity.

Social norms established through these policies can also lead to a greater collective understanding of the importance of physical activity, making it a community standard rather than an individual choice. When physical activity is embedded within the community's framework and supported by formal policies, it becomes more accessible and is more likely to be embraced by the community members, leading to increased participation in physical activities.

The other options, while potentially beneficial in individual contexts or informal settings, do not carry the same weight as formal policies in creating lasting change within a community. Personal resolutions lack the collective impact necessary for widespread change; global policies might not address specific local needs; and non-enforceable suggestions may fail to motivate community members to take action. Thus, formal written codes and social norms stand out as the most effective approach for fostering increased physical activity levels
