Short term effects of exercise

Short term effects of exercise

Learning objectives

• To be able to link short-term effects of exercise to the muscular, respiratory and cardiovascular systems.

  
  

• To show an understanding of how these effects are relevant to sporting performance.

What do we know already?

Take a look at the short clip. From what you can see here and remember from previous lessons make a list of any short term effects of exercise you can think of?

What is 'Short term'

Something that does not last very long, for example, an increased heart rate after exercise which returns to normal after a few minutes of resting.

Multiple Select

Which of these would NOT be a short term effect of exercise?

• Increased left ventricle size

• Sweating

• Muscle fatigue

• Increased HR

Copy this table into your books and fill it in as we go.

Multiple Choice

Why might an increase in temperature be beneficial for our muscular system before competetive exercise?

• Our muscles and joints become more pliable

• We can't exercise if we're cold

• Our muscles look bigger when they are warmer

Multiple Choice

Which nutrient is typically used up first by the working muscles?

• Carbohydrates

• Fats

• Protein

Open Ended

Explain how a large build up of lactic acid could effect a marathon runner during a race and why this may happen?

;

Multiple Choice

Cardiac output is

• The volume of blood pumped out of the heart per minute

• The volume of blood pumped out of the heart per beat

• The number of times the heart beats in a minute

Multiple Choice

Which exercise type predominantly causes lactate accumulation ?

• Anaerobic

• Aerobic

Short term effects of exercise on the respiratory system.

Increased brething/ventilation rate.

Increased depthg of breathing.

Oxygen debt.

Open Ended

Why is it increasing breathing rate and/or depth important during or after exercise?

Multiple Select

What do the effects of Lactic acid result in?

• Fatigue

• Energy

• Muscular pain

• Muscular growth

Mini-quiz

Let's recap what we have looked at today.

Multiple Choice

The respiratory system is anything to do with?

• Heart

• Lungs

Multiple Choice

The Cardiovascular System is anything relating to the?

• Heart

• Lungs

Multiple Select

How can muscle fatigue affect performances ?

• Slower contractions

• Less powerful

• Less accurate

Multiple Choice

During exercise your Heart beats faster. The amount of times the heart beats per minute therefore increases. This is known as?

• Increased Stroke Volume

• Increased Tidal Volume

• Increased Heart rate

• Increased Cardiac Output

Multiple Choice

What is vascular shunt?

• A hormone released from the adrenal glands

• The rise of the heart rate before exercise

• When blood is distributed to the working muscles and less to the non-essential organs

• A drop in temperature of the heart

Multiple Choice

Cardiac output is...

• the amount of oxygen produced in a full exhalation

• the amount of oxygen produced in a full inhalation

• the amount of blood pumped in one beat

• the amount of blood pumped per minute by the heart

Multiple Choice

Lactic acid will start to build...

• During low intensity exercise

• During anaerobic exercise when the body cannot remove it quicker than you produce it

• When you work hard for 5 seconds

• When the body can remove it at a rate quicker than you can produce it
