The aim of this study was to evaluate the feasibility of methods for objective 24-h sampling of physical activity among cleaners. Twenty cleaners participated in three 24-h measurements. Amount of steps, heart rate (HR), cardio-respiratory fitness, body mass index (BMI) and blood pressure were measured. The methods were feasible for the objective 24-h sampling of physical activity and cardio-respiratory fitness among cleaners. Measurements showed that the cleaners walked 20,198 +/- 4,627 steps per day. During working hours, the average cardio-respiratory load was 25 +/- 6% of heart rate reserve (HRR). The cleaners had a low estimated cardio-respiratory fitness (34mlO(2)/kg/min), a high BMI (50%, %26gt;25kg/m(2)) and blood pressure (50%, %26gt;120/%26gt;80mmHg). The high amount of steps, the relatively high cardiovascular load at work and low cardio-respiratory fitness illustrate the need for further investigation of the relationship between physical activity at work and in leisure, and cardiovascular health in this population. %26lt;br%26gt;Practitioner Summary: This study evaluated the feasibility of methods for objective 24-h sampling of physical activity among cleaners; the methods used were found to be feasible. The cleaners had a high cardiovascular load at work and low cardio-respiratory fitness, suggesting that there is a need for further investigations.
