basal metabolic rate

It is possibile that reduced slumber affects the number of calories burned while at reast( basal metabolic rate) and translates into weight gain over time.

可能是不充足的眠导致本应眠过程中消耗的卡路里（热量）受到了影响，因而导致体重增。

So evidence of sustained rapid growth, even into late juvenile and subadult stages, implies that the animals in question had relatively high basal metabolic rates.

所以，即使进入幼年晚期与亚成体阶段，仍持续快速生长的，示这些动物具有相对高的基础代谢率。
