After summarizing knowledge gaps through 2008, research on exercise commuting is reviewed for 2008–2011. Evidence-based reports on physical activity needs have emerged from many consensus panels. There seems potential to meet aerobic requirements by cycling to work. Rapid walking may also be effective in older adults. It remains unclear how far exercise commuting can strengthen muscle and bones, enhance flexibility and balance, and prevent obesity. Recent reports have characterized current commuters and urban design features favoring active commuting. Evidence has accumulated showing enhanced cardiorespiratory fitness and fewer cardiovascular risk factors among active commuters. The advantages of enhanced health outweigh disadvantages of cycling (air pollutant exposure and dangers from cars), but attempts to increase active commuting have had only limited success. In children, physical activity needs exceed commuting distances, and walking to school programs have done little to augment daily activity. Exercise commuting could contribute to the physical needs of adults, but further research is required to realize this potential.
