Cardiorespiratory fitness, happiness and satisfaction with life among Spanish adolescents
Abstract
Objectives: To analyse the interrelations among cardiorespiratory fitness, subjective happiness and satisfaction with life in adolescents. Method: The study was based on a total of 388 Spanish adolescents (207 females) aged 12-18. Cardiorespiratory fitness was assessed by means of the 20-metre shuttle run test. Subjective happiness and satisfaction with life were assessed using the Subjective Happiness Scale and Satisfaction with Life Scale respectively. The adolescents’ height and weight were measured and their body mass index (BMI) calculated. They were asked to report the educational level of the mother. Results: The linear regression analysis showed that cardiorespiratory fitness was positively associated with subjective happiness (ß non standardized = .09 ± .03, r = .128, p = .013) and satisfaction with life (ß non standardized = .31 ± .13, r = .128, p = .022), regardless of the subjects’ sex, BMI, and educational level of the mother. Conclusion: These findings suggest that adolescents with a good level of cardiorespiratory fitness are happier and more satisfied with life. Intervention studies are needed to confirm whether an intervention programme aimed at improving aerobic performance might also lead to improvements in adolescents’ level of happiness and satisfaction with life.
