Aim. Previous stud­ies that exam­ined par­tic­i­pa­tion in phys­i­cal activ­ity sug­gest­ed that ­female ado­les­cents were less ­active com­pared with males. However, the rela­tion­ship ­between phys­i­cal fit­ness, phys­i­cal activ­ity par­tic­i­pa­tion, and per­ceived ben­e­fits and bar­riers for phys­i­cal activ­ity to ado­les­cents, irre­spec­tive of gen­der, has not been made clear. This study exam­ines the asso­ci­a­tion of these fac­tors in ­female ado­les­cents.
Methods. Physical activ­ity par­tic­i­pa­tion and per­ceived ben­e­fits and bar­riers to phys­i­cal activ­ity were deter­mined in 206 sec­on­dary ­school ­female sub­jects (aged 11 to 18) using a val­i­dat­ed ques­tion­naire.
Results. Subjects with a cor­rect con­cept about opti­mal phys­i­cal activ­ity par­tic­i­pa­tion to main­tain ­health ­engaged in an activ­ity level high­er than the group with­out a cor­rect con­cept (t=2.37, p=0.02). A sig­nif­i­cant cor­re­la­tion was estab­lished ­between the phys­i­cal activ­ity par­tic­i­pa­tion with “­health” (r=0.22, p<0.001) and “body image” (r=0.17, p=0.02) in the per­ceived ben­e­fit cat­e­go­ry. The indi­vid­u­al fac­tor, “make me feel bet­ter in gen­er­al” in the “­health” cat­e­go­ry (p=0.04) and the inten­tion to par­tic­i­pate (p<0.001) were shown to be sig­nif­i­cant pre­dic­tors for phys­i­cal activ­ity par­tic­i­pa­tion. The com­bined ­effects of the regres­sion model ­explained 35.9% of the var­i­ance in par­tic­i­pa­tion in phys­i­cal activ­ity.
Conclusion. Policies to sup­port reg­u­lar phys­i­cal activ­ity par­tic­i­pa­tion at ­school and out-of-­school ­should be stra­te­gi­cal­ly devel­oped and pro­mot­ed, high­light­ing the pro­mo­tion of ­health ben­e­fits in exer­cise and the rein­force­ment of ­initial ­intent ­towards exer­cise.
