Although Differences Exist Between Genders As Well As Within
Genders on Measures of Health-related and Performance Related
Fitness, Adolescent Males and Females Have the Potential to
Make Significant Improvements Through Regular Participation in
Physical Activity.

improvements until late adolescence Females improve at a less rapid rate
than males Females plateau and regress from
mid adolescence on
