Abstract
(1) Background: The present research seeks to define and contrast an explanatory model of physical self-concept, emotional isolation, attitude towards physical education, and family functioning, and analyse the existing associations between these variables. (2) Methods: The sample was made up of 2388 adolescents (43.39% male and 56.61% female), with ages of 11–17 years (M = 13.85; SD = 1.26) from Spain. Self-concept (AF-5), Isolation (UCLA), Attitude towards Physical Education (CAEF), and Family Functioning (APGAR) were analyzed. (3) Results: Good fit was obtained for all evaluation indices included in the structural equation model, which was significantly adjusted (χ2 = 233,023; DF = 14; p < 0.001; comparative fit index (CFI) = 0.913; normalized fit index (NFI) = 0.917; incremental fit index (IFI) = 0.906; root mean square error of approximation (RMSEA) = 0.072). (4) Conclusions: Attitudes towards physical activity were found to be positive when isolation levels were low and where adequate self-concept existed, specifically in students reporting high family functioning.
Highlights
Lack of physical activity (PA) in the 21st century, both in children and in adults, has become a topic of interest worldwide in developed countries
With respect to the variables of isolation according to family functioning, we found that emotional isolation predominates above all within those students who belong to severely dysfunctional families
The main conclusions of the present study confirm that the physical dimension of self-concept is high in students who maintain low percentages in all of the dimensions of isolation
Summary
Lack of physical activity (PA) in the 21st century, both in children and in adults, has become a topic of interest worldwide in developed countries. Children do not currently meet recommendations laid out by the World Health Organisation for five to 17-year olds, of at least 60 min of moderate to vigorous PA a day [3] This should be considered alongside evidence that more young people abandon sport when they begin the secondary school stage [8,9,10]. In order to tackle this problem, it is necessary to initiate prevention processes during the adolescent phase, given that the majority of risk factors related with sedentary behaviors start at this age [11]. It is during adolescence where the processes that lead to the construction of personality are consolidated. Public Health 2020, 17, 94; doi:10.3390/ijerph17010094 www.mdpi.com/journal/ijerph
