The 5 components of physical fitness
Physical fitness is your ability to carry out tasks without undue fatigue. Learn about the components of physical fitness: cardio-respiratory endurance, muscle strength, muscle endurance, flexibility and body composition and why they are important.
that are most important, directly related to one's health, and can be directly measured are:
The good news is that you can improve your cardiovascular endurance through a sensible program of regular aerobic exercise performed within a target range of 60 to 85 percent of your maximum heart rate (MHR). Most people see significant improvement in about three months as the heart muscle grows stronger and pumps more blood with each beat. Blood vessels become more elastic, reducing blood pressure, and capillaries — the tiny vessels that actually deliver oxygen to your tissues — create more branches. Oxygen is taken up by the tissues more effectively as the density of oxygen receptors (called mitochondria) increases. The net result is a positive effect on overall health and wellness.
Body composition is a special term used in physical fitness that measures the percentage of fat, muscle, water and bone found in the human body. Measuring body composition is a specialized way to determine one's true physical fitness.

1. Cardiovascular Endurance
Cardiovascular endurance is the ability of the heart, lungs and blood vessels to deliver oxygen to your body tissues. The more efficiently your body delivers oxygen to its tissues, the lower your breathing rate is. While this may help you get a little more bottom time from each tank of air, the real benefits are being more relaxed during each dive, experiencing less fatigue and being better able to respond to challenging currents, long swims and any emergencies that may arise. Essentially, a stronger, more efficient oxygen delivery system allows you to dive with greater ease in any situation.The good news is that you can improve your cardiovascular endurance through a sensible program of regular aerobic exercise performed within a target range of 60 to 85 percent of your maximum heart rate (MHR).

2. Muscular strength
Muscular strength is defined as the maximum amount of force that a muscle can exert against some form of resistance in a single effort.
3. Muscular Endurance
Muscular endurance is the ability of a muscle or group of muscles to repeatedly exert force against resistance. Performing multiple repetitions of an exercise is a form of muscular endurance, as is running or swimming. If your muscles have to contract in a similar pattern more than one time you are using muscular endurance.
4. Flexibility
Flexibility is defined as the range of motion of your joints or the ability of your joints to move freely. It also refers to the mobility of your muscles, which allows for more movement around the joints.
5. Body Composition
Body composition is a special term used in physical fitness that measures the percentage of fat, muscle, water and bone found in the human body. Measuring body composition is a specialized way to determine one's true physical fitness.
