Question

When researchers followed a large, representative sample of U.S. youths from age 9 to 17, they found that ________?

1) two-thirds of all students received physical education in high school
2) daily free-time exercise steadily diminished, more so for girls than boys
3) a majority engaged in regular physical activity outside of school hours
4) more than half of all students experienced a daily physical education class in high school

Answer 1

Research likely indicated that daily free-time exercise decreased as U.S. youths aged, with a more pronounced decline in girls than boys, supported by data showing only a small percentage consistently participating in after-school sports.

Step-by-step explanation:

When researchers followed a large, representative sample of U.S. youths from age 9 to 17, they would likely have found that daily free-time exercise steadily diminished, more so for girls than boys. Given the data that suggests only 8 percent of students at a local high school participate in after-school sports all four years and that we still have 75 percent of students exercising for 60 minutes or less daily, it is reasonable to infer that regular physical activity is not being maintained at a high level as students age, especially among girls. It is important to note that these findings could help inform local or national health policies and youth sports programs aimed at increasing physical activity among students.
