Book excerpt: Encouraging regular physical activity (PA) is a major public health objective in the United States for several reasons, including the promotion of physical fitness. As such, the first edition of federal Physical Activity Guidelines for Americans (PAG) was released in 2008. For youth, these PAG include recommendations for aerobic and muscle-strengthening (MS) activity. PURPOSE: To examine the association between adherence to PAG and physical fitness in a nationally-representative sample of children and adolescents. METHODS: The NHANES National Youth Fitness Survey (NNYFS) collected fitness test and PA questionnaire data on children and adolescents (ages 3-15 years, n = 1,576). Fitness testing was completed for BMI (3-15 years), plank (3-15 years), modified pull-up (5-15 years), handgrip strength (6-15 years), and aerobic fitness (12-15 years) by trained test administrators. Fitness test results were converted into age- and sex-specific percentile scores. All subjects reported the number of previous days of the week that included 60 minutes of PA, while 12-15 year olds also reported the number of previous days that included MS activities. General linear models and LMS curves were created and used to compare the mean physical fitness percentile of youth reporting 7 days of 60 minutes of PA to those reporting ≤ 6 days and adolescents reporting 2 or more days of muscle-strengthening activity to those reporting ≤ 1 day. Person's correlations were made to report relationships between fitness tests. RESULTS: The contrast group for all analyses involving number of days of PA was set as 7 days PA. Boys had lower BMI percentiles, and higher percentiles on the relative grip strength, pull-up, plank, and cardiorespiratory endurance tests compared to ≤ 6 days/week (p
