Regular physical activity (PA) provides well established multiple health benefits
and can improve physical, mental, and social health for people of all ages. In 2004,
the World Health Organization (WHO) launched the first global strategy on diet and
PA,
1
which urged all countries to implement a set of recommended policy actions to increase
levels of participation. Despite much optimism that this strategy would be a catalyst
to global progress in the field of PA, reflections on the last decade have shown an
inadequate response in breadth, scale, and impact.

The latest available data show that, worldwide, 23% of adults and 81% of adolescents
(aged 11–17 years) do not meet the global recommendations.

However, the prevalence of inactivity varies considerably within and between countries
and reaches as high as 80% in some populations, and levels of inactivity increase
with economic development (as measured by gross domestic product) due to the influence
of changing patterns of transportation, use of technology, urbanization, and cultural
values. Of particular concern are the significant inequities seen in many countries,
with girls, women, older adults, less advantaged, the poor, people with disabilities
and chronic disease, and rural communities, having lower levels of PA due to poor
access to safe, accessible, affordable places, and appropriate opportunities to be
physically active that meet their needs.
Barriers to progress on PA in many countries, particularly in Asia, Africa, and Latin
America, include the lack of local evidence to inform and convince government decision
and policy makers to prioritize and resource implementation of PA interventions. There
is also a need for more sharing of intervention resources and positive experiences
within and between countries and regions. This special issue of the Journal of Sport
and Health Science has a global perspective on the science and practice of PA, which
brings new evidence from a diverse set of countries to share knowledge and inform
global and national progress. This is timely, as in 2017 WHO was mandated to develop
a new global action plan on PA to reignite global efforts and align national responses
toward promoting PA within the new opportunities and agenda set by the 2030 Sustainable
Development Goals. Launch of this new action plan is planned for mid-2018 and feedback
from the wide consultation undertaken to date is already ensuring that the latest
scientific evidence informs the proposed menu of effective policy opportunities.
Based on the strong body of international evidence, it is clear that countries will
need to respond with policy actions aimed at ensuring that all people have supportive
environments that provide equitable access to safe, appropriate spaces and places
for PA, combined with policies that strengthen the provision of programs and opportunities,
across multiple settings, tailored to the needs of populations, particularly the least
active, disadvantaged, and marginalized communities. Effective policy implementation
to increase the population level of PA, and to reduce inequities, will require successful
engagement and partnerships with many sectors outside of health, which include transport,
urban planning, sports, and education. Cities, local municipalities, schools, and
workplaces are key settings and well placed to lead local change and share successful
projects to increase both political and community awareness of the importance of everyone
being more active, at all ages and according to ability.
Overcoming the institutional and professional challenges to work effectively across
government and in partnership with non-government, civil society, and private sectors
will be essential. This challenge also presents an opportunity to the research and
scientific community not only because multisector partnerships are embedded in the
Sustainable Development Agenda but also because much more needs to be known about
how to effectively establish and maintain such working arrangements to optimize the
different contributions each discipline can contribute. Understanding and assessing
the impact of different models of how health, sport, transport, and other sectors
can effectively combine to impact levels of participation in different contexts and
cultures is a pressing research priority.
There is no time to lose. The 2011 High Level Meeting on Non-communicable Diseases
(NCDs)
4
and the resulting Political Declaration and WHO Global Action Plan on NCDs Prevention
and Control 2013–2020
5
placed a priority on addressing NCDs risk factors and, in turn, their determinants.
Targets were set and for the first time a global target of reducing physical inactivity
by 10% by 2025 provided a clear focus for action. Achieving this target will require
all countries to support their national actions plans with strong systems of research,
surveillance, governance, financing, and advocacy. Building capacity in all of these
areas will require the leadership and contributions of the academic and scientific
community to assist policy makers and practitioners. It is only by all sectors and
the global community joining together in strong cooperation that we can achieve the
shared goal of more active societies by 2025. More information on the development
and process of the global action plan is available and wide engagement from all sectors
is welcomed and encouraged.
