However there are no existing measuring methods for estimating time costs. The aim of this article is to describe a way to measure the costs of time spent on physical activity. We propose a model for measuring these time costs and present the results of a pilot study applying this model to different groups of exercisers. Methods We began this investigation by developing a model for measuring the time spent on exercise based on the most important theoretical frameworks for valuing time. In the model the value of utility in anticipation expected health benefits of performing exercise is expressed in terms of health-related quality of life. With this approach the cost of the time spent on exercise is defined as the value of utility in use of leisure activity forgone minus the value of utility in use of exercise. Utility in use for exercise is valued in comparison with utility in use for leisure activity forgone and utility in use for work. To put the model into practice we developed a questionnaire with the aim of investigating the valuations made by exercisers and applied this questionnaire among more experienced and less experienced exercisers. Results Less experienced exercisers valued the time spent on exercise as being equal to 26 of net wages while more experienced exercisers valued this time at 7 of net wages p 0.001 . The higher time costs seen among the less experienced exercisers correlated to a less positive experience of exercise and a more positive experience of the lost
