Did The PACER Scores Improve For The Boys And Girls As The Children

Questions for Lab Activity 15.1 _______________________________________________________________

Did the PACER scores improve for the boys and for the girls as the children aged? Which average scores demonstrate this trend? Did you expect these results? Why or why not?
Yes, as a group, the PACER scores for the boys and girls improved as the children aged.
The group average score demonstrates this trend.
The girls scores seemed to increase almost by 10 each year.
The boys scores were a little more variable but increased from an average of 45.2 to 63.8 after 3 years.
I did expect this trend because as you age, your body starts to mature more, and endurance increases due to body size and lean muscle mass

Was performance linear—that is, did it improve by the same amount every year? What was the difference between year 1 and year 2 for both boys and girls, respectively? Between year 2 and year 3? Is this change consistent with what you know about maturation? How?

For the boys, there was an increase of 3.0 points from year 1 to year 2, but a higher increase of over 16 points from year 2 to year 3.
However, for girls, there was higher increase between the first two years of about 8 points and 10 points from year 2 to year 3.
This change is consistent because maximal oxygen uptake increases linearly in children, where girls usually reach their peak around 12 or 13 years old while boys continue until about the age of
