One of the most often suggested strategies for enhancing public health through physical activity (PA) is to make use of the need for transportation between home and work/study place through walking or bicycling. This paper presents a study based on a questionnaire and map distributed to about 2000 physically active commuters in Greater Stockholm. Five variables are examined: distance, commuting time, velocity, perceived exertion and body mass index (BMI). The results demonstrate that most of the commuters meet the WHO physical activity recommendations. A methodological conclusion from the study is that subjective estimations of commuting distances do not give reliable values. Suggested methods for more accurate values are measuring routes drawn on maps or to use the straight-line distance between home and work/study place together with a correction factor (A).
