Lesson video

Hello, I'm Mr. Whitehead, and welcome to lesson two of the RSHE Healthy Lifestyle: Physical Fitness and Healthy Eating unit.

Today we're going to be doing a lesson on our bodies when exercising.

In this lesson, you will need the following items: a piece of paper or a pad, and a pen or a pencil.

Now let's look at the agenda of this lesson.

So you should have already completed the intro quiz.

We will then look at some key words.

We will then look at the scientific effects of physical activity and exercise.

You will then complete a mind map on the bodies effects on the physical activity.

And finally, you will do the exit quiz at the end of this lesson.

To help you better understand the two different types of exercise, let's have a look at some key words.

Aerobic exercise is exercise that involves or improves oxygen consumption by the body.

Aerobic simply means with oxygen.

For example, long distance running.

Whereas anaerobic exercise is performed in the absence of oxygen.

It is high-intensity, short duration exercise.

Anaerobic exercise can only be sustained for a short period of time.

For example, high-intensity interval training.

In a moment, I'm going to ask you to stop the video and consider this statement.

What is the difference between exercise and physical activity? So, now's your chance to have a little think about this question.

Once you return, we'll go through the answer.

So take a few moments just to pause the video now and return once you've had a little think.

Welcome back.

Now let's go through the answers.

So, firstly, let's start with physical activity.

Physical activity is any body movement produced by skeletal muscles that require energy expenditure.

For example, putting your hand up in a classroom, walk into the door.

That will be classed as a physical activity.

Whereas exercise is physical activity that is planned, structured, and repetitive for the purpose of conditioning any part of the body.

It's used to improve health and maintain fitness.

In a few moments, I'm going to ask you to pause the video and complete the following task.

So using the knowledge that you already know about the two different types of exercise, complete this task.

So sort these various types of exercise into aerobic and anaerobic.

Weightlifting, swimming laps, cycling, brisk walk, rowing, sprints, cross country running, and high-intensity interval training.

Now remember, aerobic is with oxygen and anaerobic is without oxygen.

Okay, take a few moments just to pause the video, and have a go at this using your pen and paper.

Once you've completed it, return back to the lesson and we'll go through the answers.

Welcome back again.

Let's go through the answers.

Okay, so here's the answers.

Now, check to see what you've got to see if you've got the correct answers.

Don't worry if not, just make a few amendments on your paper and then we can move on.

Just to note, aerobic exercise is exercises done for a longer period of time where anaerobic, we can only manage for short periods of time.

Now let's have a look on the effects on the brain when we exercise.

So as we exercise, our hearts pump more blood around our body, which increases the amount of blood that goes to our brain.

And when we get more blood in the brain, this encourages the production of helpful hormones including BDNF, which is a fertiliser for the brain which helps our cells grow, serotonin, which increases motivation, and dopamine, which improves decision-making.

Regular exercise is linked to being able to handle stress better.

So it is important that when we have assessments and exams in school that we exercise regularly so we can handle the stress of those exams and assessments.

So it is important that when we have assessments and exams in school that we exercise regularly so we can handle the stress of those exams and assessments.

Based on what we know about the effects on the brain when we exercise, answer the following statement.

Exercise promotes the production of hormones in the brain.

Is that true or is that false? Okay, take a few moments just to pause the video, have a little think about this one.

And then once you think you've got the answer, resume the video and we'll go through the answer.

Welcome back.

The answer was true.

Exercise promotes useful hormones such as BDNF, serotonin, and dopamine when we exercise.

Well done if you got that one right.

Now let's move on to the effects on the heart when we exercise.

So, firstly, our body pumps blood around the body to working parts.

So as we're moving our legs and our arms, our heart is constantly pumping blood to those working areas.

The more our heart pumps blood, our heart becomes more efficient, and it becomes more efficient by pumping more blood but in less beats.

And the benefits of this include better blood flow through our arteries, more energy, better sleep, and it helps us maintain a healthy weight.

Okay, let's have a little test about this knowledge.

Based on the knowledge that we know about the effects on the heart when we exercise, answer this following question.

So regular physical activity increases the efficiency of our heart.

Efficiency in our heart results in which of the following? Less blood and less beats, more blood and more beats, less blood and more beats, or more blood and less beats? Now read these carefully and think back to the previous slide.

And now I want you to pause the video, have a quick think, and resume the video when you're ready to move on.

Welcome back.

So have you got the right answer? Let's have a look.

So the answer is more blood and less beats.

So as our heart gets more efficient, it produces more blood but in less beats.

Okay, let's move on.

Now let's take a look at perspiration at work.

So to regulate our body's temperature, our bodies perspire, which is also known as sweating.

Our sweat is mainly made up of water, chemicals, sugar, and salt.

And perspiration detoxes the body to get rid of any harmful chemicals and salt that our body no longer needs.

Now it is really crucial that we wash after sweating to ensure that our pores in our skin don't become blocked.

Now listen very carefully to the following statement and decide whether you think it is true or false.

Perspiration is an important body process that heats up our body to regulate the temperature.

Is that true or is that false? Now take a moment to pause the video and have a think about this question.

You may want to read it again to ensure that you fully understand the statement.

Welcome back.

Now let's see if you've got the correct answer.

So the answer is false.

Perspiration regulates our body by cooling it down, not heating it up.

Well done if you got that one right.

Okay, let's move on to one of our final tasks.

You're now going to tie all the information that we've learned in today's lesson to create a mind map.

So your task.

You need to create a mind map in your exercise book or on paper about how our body works when we exercise.

You need to include the following: difference between physical activity and exercise, the effects of exercise on our brain and our heart, and how our bodies respire to regulate body temperature.

And you may also want to include any drawings.

Now take this moment to pause the lesson and complete the following mind map.

Once you've completed the mind map, please resume the lesson and we can complete the end of the lesson.

Welcome back.

To finish off, we're going to have a quick recap of everything that we've learned throughout this lesson.

If you haven't already, please make sure that you've got everything down from this table on your mind map.

So, physical activity is any bodily movement that requires any energy expenditure.

Aerobic exercise is with oxygen for a long period of time and anaerobic exercise is without oxygen for a short period of time.

So hormones are encouraged in our brain when we exercise more, through serotonin, dopamine, and BDNF.

As we exercise, our bodies become more efficient through the flow of blood through our arteries.

As our heart becomes more efficient, our hearts pump more blood but in less beats.

To regulate our body's temperature, our bodies perspire, which is also known as sweating, which keeps our bodies at regulated temperature and detoxes of any harmful chemicals, salts, and sugars.

And finally, please ask one of your parents or guardians if you can share your work on Twitter.

We'd love to see your mind maps.

Please use the @OakNational and #LearnwithOak to ensure that we see your fantastic work.

Thank you for engaging so well throughout this lesson.
