About the thesis

Cardiovascular disease is the most frequent cause of death. Cleaners exposed to high occupational physical activity suffer from an increased prevalence of cardiovascular disease.

This PhD-study investigated whether this 4-months aerobic exercise worksite intervention would improve or impair risk factors for cardiovascular disease. The results showed that the intervention led to a lowered risk for cardiovascular disease, via an enhanced cardiorespiratory fitness, a reduced resting heart rate, and aerobic workload. The aerobic exercise led to an elevated blood pressure.

Further studies are needed to understand the mechanisms behind the cardiovascular effects seen from high occupational physical activity, and to make recommendations for the prevention of cardiovascular disease among workers exposed to high occupational physical activity and high aerobic workloads.
