Carter and beaupré (2001) discuss an interesting finding by lanyon and rubin in 1984. it was suggested that the number of cycles of loading per dav and the maximum achieved strain both serve as mechanobiological stimuli for bone growth. in particular, they found that bone mass was maintained (i. e., production and removal were balanced) given a strain history of 4 cycles/day at a maximum value of 0.002 or similarly at 100 cycles/day at a maximum value between 0.0005 and 0.001 (assume 0.0008). they suggested that these combined effects can be accounted for via a "daily bone stimulus" parameter ξ that is computed via the following formula
