Give one example of physical activity.
Running / walking / swimming / cycling
If a person eats more energy than they use, they will...
Gain weight
Exercise makes muscles...
stronger
Hypertension is _______ blood pressure
high
Name one disease that can be reduced by physical activity.
Obesity / hypertension / cardiovascular disease / type 2 diabetes / osteoporosis
What is active lifestyle?
A lifestyle that integrates physical activity into daily routines, such as walking, cycling, or chores, rather than relying solely on structured exercise
What is energy intake?
The total calories or kilojoules consumed from food and drink, <<measured in energy content rather than nutrients>>
Which three main body systems help us move?
Muscular system and skeletal system (musculoskeletal system) + nervous system
What is obesity?
A disease characterized by excessive fat accumulation <<that poses serious risks to health>>
How does exercise help prevent obesity?
By creating a calorie deficit to reduce fat mass <<improving metabolic health, and maintaining weight loss>>
Why do children and adults need different levels of activity?
body mass / growth / fitness level / activity level
What is energy expenditure?
The total amount of calories the body burns in a day <<to maintain vital functions, digest food, and perform physical activity>>
Moderate exercise makes the immune system...
stronger
Which disease is linked to weak bones and risk of fractures?
Osteoporosis
Exercise keeps the heart healthy. Which disease does this help prevent?
Cardiovascular disease
A person is active but do not see the usual benefits. Suggest why
Diet may be poor / not enough rest / too much stress / overtraining
Name the three parts of energy balance.
Energy intake, energy consumption, energy storage
A person trains very hard every day but still gets sick often. Explain why.
Immune system becomes weaker due to too much stress and not enough recovery
Type 2 diabetes means...
the body resists insulin or does not produce enough, causing high blood sugar levels
Exercise improves blood flow. Why is this good for health?
It helps the heart and reduces cardiovascular disease risk
Two people do the same exercise. One gets fitter, one does not. Suggest why?
Differences in age / fitness / effort / genetics
A person exercises a lot but does not lose weight - suggest why
Energy intake is still high / eating too much OR another health condition is affecting their metabolism
A person gets tired quickly during exercise. Which two body systems may not be working well? Explain.
Cardiovascular system - not enough oxygen delivery for the aerobic energy systems, muscles cannot contract because of lack of energy AND muscular system - low muscle strength/endurance, muscles fatigue quickly
Two diseases are linked to energy balance and diet. Name them and explain.
Exercise reduces disease risk in different ways. Name two ways.
Increases energy use (helps control weight)
Improves heart function / blood flow
Improves blood glucose control
Increases bone density and reduces the risk of osteoporosis
Improves "good cholesterole" (HDL) levels and reduces "bad cholesterole" (LDL)
Improves immune system function
