Recommendations for future research

Information is required to determine representative values for PAL for light, moderate and strenuous physical activity in the older population, because the ranges of values will differ from those appropriate for younger adults. Within the older population, determination of PAL for three age groups (65-75, 76-85, 86+) and in both men and women is important. Values for light, moderate and strenuous activity should be representative of population data on physical activity in this age group. In addition, information is required from older individuals in both affluent and developing countries.
