Resumen
(1) Background: This study aims to investigate the association between different levels of physical activity (PAL) and health-related quality of life (HRQoL) in a random sample of the adult population; (2) Methods: The study material comprised 1100 adults of the city of Brasov, Romania (700 men, 400 women), aged 30?45 years old. We used the short version of the International Physical Activity Questionnaire Short Form (IPAQ-SF) and Short-Form Health Survey (SF-36) to assess PAL and HRQoL, respectively; (3) Results: The differences in the number of respondents in groups assessing their HRQoL differently and PA were statistically significant (p < 0.001), both among men and women. The PAL was shown to be positively correlated with the adult HROoL domains; (4) Conclusions: Our results confirm that the highest PAL values were associated with more favorable scores in HRQoL dimensions among the adult population.
