摘要：This study examined the relationships between parental support for physical activity, weekly Physical Activity (PA) practice frequency, and self-efficacy expectations to overcome barriers to participation. A total of 335 adolescents took part in this pilot cross-sectional study. The results show that boys and girls who attribute parents to a high level of instrumental support, modeling and behavioral limitation are allocated to higher number of days per week to perform the physical-sport activity during a minimum interval of sixty minutes and were more self-efficacious in their practice. Likewise, the frequency of practice of the activity and self-efficacy were higher in the case of boys.
