摘要：Physical inactivity is an important risk factor in several highly prevalent diseases, being associated with worse quality of life and higher mortality. Despite the implementation of a several global, national and local policy instruments and strategies to promote physical activity (PA), including Internet platforms and advertising campaign, approximately two thirds of the European adult population reports low adherence to an active lifestyle, impairing health benefits that exercise can provide. Increasing efforts to provide adequate information have been made, and the use of new technologies tools has increased, but little investigation focus on the effect of information exposure on knowledge retention, regarding effects of physical inactivity in health. The objective of the present study is to evaluate differences among people in the use of new information technologies as information source on PA, regarding their perceptions of benefits of an active lifestyle and characteristics of adequate physical activity to health improvement. The study included a randomly recruited sample of 879 subjects (53% males; 47% females), age 42.3±19.4 years old. A survey was designed to (1) identify main information sources; (2) relate perceived knowledge and PA information sources; (3) relate knowledge retention on adequate PA for health benefits and PA information sources; (4) relate perceived necessity of more information regarding PA and information sources and (5) relate PA levels and information sources. Results show that two information sources (teacher and sport professionals) positively influence perception of proper PA information. Results also found teachers, Internet and sport professionals as PA information sources that most influence their users, regarding Knowledge retention. We also found that rely on friends/family; teachers, Internet and sport professionals as PA information sources positively influence the adoption of an active lifestyle.
