The purpose of the present report is to update and clarify the 1995 recommendations on the types and amounts of physical activity needed by healthy adults to improve and maintain health.
Physical activity and public health. A recommendation from the Centers for Disease Control and Prevention and the American College of Sports Medicine.
Every US adult should accumulate 30 minutes or more of moderate-intensity physical activity on most, preferably all, days of the week.

The authors evaluate participants from the 2003-2004 National Health and Nutrition Examination Survey aged >/=6 years who wore an activity monitor for up to 7 days to provide the first objective measure of the amount of time spent in sedentary behavior in the US population.

Future claims about the effects of sedentary, light, and moderate-to-vigorous activities on health outcomes should be supported by data from studies in which all levels of physical activity are differentiated clearly and measured independently.
Age and gender differences in objectively measured physical activity in youth.
The results support the notion that PA declines rapidly during childhood and adolescence and that accelerometers are feasible alternatives to self-report methods in moderately sized population-level surveillance studies.
Conducting accelerometer-based activity assessments in field-based research.
Accelerometer-based activity assessments requires careful planning and the use of appropriate strategies to increase compliance, and face-to-face distribution and collection of accelerometers is probably the best option in field-based research, but deliveries by express carrier or registered mail is a viable option.
Physical Activity Assessment in Children and Adolescents
The strengths and limitations of the methods used to evaluate physical activity in children and adolescents are summarized and future investigations of physical activity instruments should validate the novel instrument against a higher standard.

The Canadian 24-Hour Movement Guidelines for Children and Youth: An Integration of Physical Activity, Sedentary Behaviour, and Sleep provide evidence-informed recommendations for a healthy day (24 h), comprising a combination of sleep, sedentary behaviours, light-, moderate-, and vigorous-intensity physical activity.

Results indicate that a 7-d monitoring protocol provides reliable estimates of usual physical activity behavior in children and adolescents and accounts for potentially important differences in weekend versus weekday activity behavior as well as differences in activity patterns within a given day.
