a

All correlations were significant at the P < .001. The correlations to the left of the forward slash (/) are for boys and the correlations to the right of the forward slash are for girls (i.e., boys/girls).

b

Total number of activities adolescents participated in during the past 12 months out of 35 activity types.

c

Total number of team sports/weightlifting activities (baseball/softball, basketball, football, and weightlifting) adolescents participated in during the past 12 months.

d

Total number of individual activities (jump roping, roller blading/roller skating, running/jogging, swimming, and walking) adolescents participated in during the past 12 months.

e

Total number of other competitive/recreational activities (Frisbee, racquetball, soccer, tennis, and volleyball) adolescents participated in during the past 12 months.

f

Averaged scale score computed from a 5-item scale that measured enjoyment of PA. Higher scores indicate enjoyment toward PA.

g

Number of days (from 1 to 7 days) that adolescents engaged in PA for at least 60 minutes.
