Estimating duration-distance relations in cycle commuting in the general population

• It is important to estimate the duration-distance relation in cycle commuting in the general  population since this enables analyses of the potential for various public health outcomes. Therefore, the aim is to estimate this relation in the Swedish adult population of 2015. For that purpose, the first step was to establish it for adult male and female cycle commuters in Greater Stockholm, Sweden. Whether or not the slopes of these relations needed to be altered in order to make them representative of the general population was evaluated by comparing the levels of maximal oxygen uptake in samples of commuter cyclists and the population. The measure used was the maximal oxygen uptake divided by both the body weight and a cycle weight of 18.5 kg. The body weights in the population samples were adjusted to mirror relevant levels in 2015. Age adjustments for the duration–distance relations were calculated on the basis of the maximal oxygen uptake in the population samples aged 20–65 years. The duration-distance relations of the cycle commuters were downscaled by about 24–28% to mirror levels in the general population. The empirical formula for the distance (D, km) was based on duration (T, minutes)  x  speed (km/min)  x  a correction factor from cycle commuter to the general population  x  age adjustment (A, years). For the males in the general population the formula was: D = T  x  20.76 km/h  x  0.719  x  (1.676 – 0.0147  x  A). For females, the  formula was: D = T  x  16.14 km/h  x  0.763  x  (1.604 – 0.0129  x  A). These formulas, combined with distributions of route distances between home and work in the population, enable realistic evaluations of the potential for different public health outcomes through cycle commuting.
