THE CARDIOVACULAR SYSTEM

Untitled Slide

• The cardiovascular system consists of the heart, blood vessels, and the approximately 5 liters of blood that the blood vessels transports.
• It transports oxygen, nutrients, hormones, and cellular waste products throughout the body. It's powered by the heart, When at rest the average heart pumps over 5 liters of blood throughout the body every minute.

THE TWO PRIMARY CIRCULATIONS

• the pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs, the blood then picks up oxygen and returns to the left side of the heart . The pumping chambers of this circulation is the right atrium and right ventricle

Untitled Slide

• Systemetic circulation carries oxygenated blood from the left side of the heart to all of the tissues of the body. This circulation removes waste from body tissues and returns deoxygenated blood to the right side of the heart. The left atrium and left ventricle are the pumping chambers of the systemetic circulation loop

MAYWEATHER V PACQUIAO

• When training for the Pacquiao fight Mayweather was chopping trees with an axe. He believes “throwback training” helps to develop his strength endurance and explosive force.
• Mayweather runs 5-8 miles per day, Ahead of the fight with Pacquiao he taken up swimming for the extra cardiovascular fitness and muscle endurance.

SWIMMING

• Swimming is an exercise that works many different muscles like your arms, legs and core.
• When swimming, your arms, legs and core are demanding more oxygen, this causes your heart to pump faster.
• As a result of regular swimming exercise, your heart will become stronger and able to pump more blood with each contraction.

LONG TERM EFFECTS

• The long-term effect of regular swimming is that you will have a lower resting pulse and breathing rates.
• A slower pulse is a sign that your heart is stronger and capable of pumping more blood with each contraction.

LONG TERM EFFECTS

• It also shows that blood vessels may be more open and flexible than they were before you started swimming regularly and the lower breathing rate reflects the increased lung capacity.
