00:01
Okay, in order to solve this question, let's talk about factors that may increase metabolic grade.
00:06
Third, shivering.
00:10
Maybe you have experienced that when you have or when you are in very low temperatures, your body starts to do this process of shivering, okay? and what is this process actually? well, when you have or when you are in seeing environments with low temperature, there are going to be nerve impulses.
00:36
Nerve impulses that are going to be sent to the hypothalamus.
00:44
Okay, and these nerve impulses are going to be released by hypothalamus, and these nerve impulses are going to reach, i'm sorry, this is like this, okay, the hyposalamus is going to send nerve impulses to the skeletal muscle, okay, to the skeletal muscle, for example, your bicep, your tricep, and those voluntary muscles, okay? and what it is going to cause is that there is going to be a rapid contractions.
01:21
Grapeat contractions that are going to generate heat in order to, in order to guise the temperature and maintain homostasis without the body.
01:34
So because of these graphic contractions, we are increasing practically metabolic grade.
01:44
Okay, because we're causing graphic contractions of the muscle and this is going to increase a metabolic rate in production of carbon dioxide for example and use of oxygen to in order to produce heat also when we sleep our body is at west remember that there is always a basal metabolism okay so particularly when we're sleeping we are burning fats for example not so much but we're burning fats because of metabolic activity okay however we are not like metabolic activity when we are sleeping, but we're practically decreased metabolic activity.
02:27
Okay, this is why it is called basal metabolic activity.
02:31
And also, when, as in opposite to this case, causing rapid contractions of skeletal muscles, by decreasing muscle activity, we're going to decrease metabolic aid...
