Resumen:
The aim of this study is to analyse the correlation between the main components of physical activity (strength, flexibility and resistance) and quality of life examined in a work environment. Method: In a randomized, controlled trial throughout one year of follow-up patients were evaluated by their quality of life (SF-36 health survey) and their physical exercise (resistance measured by cardiopulmonary stress test; strength and flexibility based on Eurofit Fitness Test Battery). The intervention group received a personalized exercise plan and the control group attended an informative talk with general guidelines. Results: Both groups improved their physical activity, however, Intervention group had better results 48,7 than Control group 40,87 (p=0,03). Workers with better physical activity proved a greater quality of life (OR:6,69; IC95%:1,48-30,20), being the resistance the major contributing component (OR:8,64; IC95%:1,69-44,04). Conclusion: Workers with a higher level of physical exercise are associated with improved quality of life.
