Activity 5. Activating prior knowledge
Below is a Venn diagram. Your task is to differentiate the two given words and write it
where the word is being aligned, while write their similarities in the middle where the
two circles overlaps.
Physical activity Exercise
Physical activity is defined as any bodily movement
produced by skeletal muscles that require energy
expenditure. Popular ways to be active are through
walking, cycling, sports and recreation, and can be
done at any level of skill and for enjoyment.
Exercise is planned, structured, repetitive and
intentional movement intended to improve or
maintain physical fitness. Exercise is a subcategory
of physical activity.
Types of Physical Activities
The four main types of physical activity are aerobic, muscle-strengthening, bone-
strengthening, and stretching. Aerobic activity is the type that benefits your heart and lungs
the most.
Aerobic activity
 moves your large muscles, such as those in your arms and legs. Running, swimming,
walking, bicycling, dancing, and doing jumping jacks are examples of aerobic
activity. Aerobic activity also is called endurance activity.

 makes your heart beat faster than usual. You also breathe harder during this type of
activity. Over time, regular aerobic activity makes your heart and lungs stronger and
able to work better.
Muscle-Strengthening
 activities improve the strength, power, and endurance of your muscles. Doing pushups
and situps, lifting weights, climbing stairs, and digging in the garden are examples of
muscle-strengthening activities.
Bone-Strengthening
 bone-strengthening activities, your feet, legs, or arms support your body's weight, and
your muscles push against your bones. This helps make your bones strong. Running,
walking, jumping rope, and lifting weights are examples of bone-strengthening
activities.
Muscle-strengthening and bone-strengthening activities also can be aerobic, depending on
whether they make your heart and lungs work harder than usual. For example, running is both
an aerobic activity and a bone-strengthening activity.
Stretching
 helps improve your flexibility and your ability to fully move your joints. Touching
your toes, doing side stretches, and doing yoga exercises are examples of stretching.
Aerobic Activity Level of Intensity
You can do aerobic activity with light, moderate, or vigorous intensity. Moderate- and
vigorous-intensity aerobic activities are better for your heart than light-intensity activities.
