Larger animals also have slower metabolic rates than smaller animals.

大型动物的代谢率也比小型动物慢。

A high metabolic rate means more energy is available to process them.

高代谢率意味着多的能量处理信息。

What hibernation really is, it's a reduction in the metabolic rate.

冬眠实际上是新陈代谢率的降低。

The first factor is our basal metabolic rate, or BMR.

第一个因素就是基础代谢率，也就是 BMR。

They've undergone selection for a higher metabolic rate that increases heat production.

他们有高的新陈代谢率，产生多热量来挺过自然选择的考验。

Scientists think that lower metabolic rates are directly linked with longer lifespans.

科学家认为低代谢率与长寿直接相关。

Humans and all other animals have what's called a basal metabolic rate.

These physical and behavioral adaptations minimize the sloth's energy expenditure, or metabolic rate.

这些身体和行为上的适应使树懒的能量消耗或代谢率降到最低。

A bat in flight elevates its basal metabolic rate up to 15 fold.

飞行中的蝙蝠将其基础代谢率提高了 15 倍。

Similarly, many other people had looked at the metabolic rates of many of the same species.

Not only did most of the participants in the study regain their weight, but their metabolic rates changed.

大部分的参赛者不但恢复了体重，而且他们的新陈代谢速率也发生了变化。

The researchers noted that the lower metabolic rates also have the effect of making a person feel lighter.

研究人员指出，代谢率降低还能令人们感觉轻盈。

And to put that in context, a human at full speed running is only doubling their metabolic rate.

在此背景下，一个全速奔跑的人的代谢率只会增加一倍。

Mr Healy reasoned that the main constraints on an animal's CFF are its size and its metabolic rate.

Healy先生推断，动物CFF的主要限制来自于其体型及其新陈代谢速度。

What's more, high-intensity training helps boost your metabolic rate, which means you burn more energy even at rest.

而且，高强度训练会帮助你加强代谢速率，这意味着你即使在休息的时候也能消耗多能量。

In other words, whenever AEE increased, one's basal metabolic rate dropped, thus leading to an energy compensation.

换句话说，当 AEE 增加时，一个人的基础代谢率下降，从而导致能量补偿。

In the new study, researchers measured the metabolic rate of 16 young women as they performed light office duties.

而新发表的研究则是测试从事轻度工作时16名年轻女性的代谢速率。

In particular, the researchers looked at the participants' resting metabolic rates: the calories their bodies burned at rest.

研究人员尤其关注选手的静息代谢率，也就是他们在休息时身体会消耗多少卡路里。

B. Too much workout often slows metabolic rates.

B. 过多的锻炼通常会减慢新陈代谢率。
