However, body mass will scale with approximately the cube of height. Now I will again save you some calculator time by converting the table above to three relative performance matrices. At this point some observations are in order. At face value, it seems that the scaling choices made are appropriate. The bodyweight I have used is absolute bodyweight, which does not account for differences in body composition, which are significant between these two groups.
Lightweight men have more muscle mass at the same bodyweight.
Whether this completely accounts for the difference would require actual body composition data for the subjects, which I do not have. This would account for the difference in relative anaerobic capacity observed in these similary trained groups. Second, scaling the longer tests based on allometric assumptions also seems appropriate. This larger difference is consistent with the relatively lower performance level in the U.S lightweight women on the water, but is still reasonable. Thus, it appears that Maximal oxygen consumption differences can adaquately explain scaled power differences.
