Aerobic Fitness Results from The President’s Challenge 1-mile Endurance Run.

<p>Performance level national standards were used to classify fitness of urban school students. Percentage of the population at each grade level (elementary, middle, and high school) is shown. The 85^th and 50^th percentiles are benchmarks for Presidential awards.</p

Body Mass Index and BMI-for-age Percentiles of Urban Female and Male Students.

<p>Body mass index (BMI) for female students (A) and male students (B) depicted on BMI-for-age percentile growth charts [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0138175#pone.0138175.ref014" target="_blank">14</a>]. Each symbol represents one student’s BMI (N = 4673). Severe obesity was defined as class 2 obesity (≥ 120% of the 95^th percentile of BMI-for-age) or class 3 obesity (≥ 140% of the 95^th percentile) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0138175#pone.0138175.ref002" target="_blank">2</a>].</p
