COURSE: Essentials of Nutrition

Answer 1

1)Muscular Endurance
2)Cardiovascular Endurance
3)Flexibility
4)Muscular Strength

Muscular Endurance

Endurance is the capacity of our muscles to perform contractions for extended periods of time. It is not just lifting or carrying something for a few seconds but the activities for which the muscles are used for minutes

Cardiovascular Endurance

Cardiovascular endurance is our body's capacity to keep up with exercise like swimming, running, jogging cycling, and anything that forces your cardiovascular system (lungs, heart, blood vessels) to work for extended periods of time. Together, the heart and lungs fuel our body with the oxygen needed by our muscles, ensuring that they have the oxygen needed for the work they are doing.

Flexibility

Flexibility is one of the most crucial, yet often overlooked, components of physical fitness. Without flexibility, the muscles and joints would grow inflexible and movement would be limited. Flexibility training guarantee that our body can move through its entire range of motion without pain or stiffness.

Muscular Strength

This is the "power" that helps us to lift and carry heavy objects. Without muscular strength, our body would be weak and unable to keep up with the demands placed upon it.

Carbohydrate is the central nutrient that fuels exercise of a moderate to high intensity.

Fat fuel low-intensity exercise for long periods of time.

Proteins are normally used to maintain and repair body tissues and are not generally used to power muscle activity

Below things can be tried to increase our physical activity

Exercise regularly.

Don't smoke.

Get enough sleep.

Maintain a healthy weight.

Eat a “healthy diet.”

Take the stairs instead of the elevator.

Park farther away from the front door.

Stand instead of sitting (this burns more calories)

Take a walk on your lunch break.
