The effects of an unstable shoe on energy expenditure and knee and ankle joint moments during walking in women

摘要

In general, with the Unstable shoes the subjects burned more kilocalories during walking, and managed to do so without increasing the peak loads experienced by the knee joint. The greater EE could be explained by the greater mass of the Unstable shoes which were approximately 120 grams heavier than the Control shoes. It has been shown that 100 grams of additional shoe mass increases EE by about 1% per minute (Frederick 1984), therefore the 3.4% increase cannot be attributed to mass alone.
