Effect of cadence and power output on energy cost across different age range elderly during cycling

The reduced cardiorespiratory function and muscle performance in the elderly significantly minify an individual's functional aerobic capacity. Some inactive older adults are in an age range that theoretically places them right around their aerobic capacity threshold. Any further decline may make them unable to complete daily activities and then have a negative influence on living independently. The most commonly cited estimation is that oxygen consumption declines at a rate of 1% per year after the third decade of life. The difference is apparent with subtle change in age. As such, the purpose of this study was to examine the influence of age on changes in energy cost in two significantly different age elderly groups and one young counterparts group.
