2.1.The Components of Fitness
Health is a state of complete mental, physical and social well being where as fitness is the ability to meet the demands of a physical task.

Basic fitness can be classified in four main components: strength, speed, stamina and flexibility. However, exercise scientists have identified nine components that comprise the definition of fitness:

• Strength - the extent to which muscles can exert force by contracting against resistance (e.g. holding or restraining an object or person)
• Power - the ability to exert maximum muscular contraction instantly in an explosive burst of movements. The two components of power are strength and speed. (e.g. jumping or a sprint start)
• Agility - the ability to perform a series of explosive power movements in rapid succession in opposing directions (e.g. ZigZag running or cutting movements)
• Balance - the ability to control the body's position, either stationary (e.g. a handstand) or while moving (e.g. a gymnastics stunt)
• Flexibility - the ability to achieve an extended range of motion without being impeded by excess tissue, i.e. fat or muscle (e.g. executing a leg split)
• Local Muscle Endurance - a single muscle's ability to perform sustained work (e.g. rowing or cycling)
• Cardiovascular Endurance - the heart's ability to deliver blood to working muscles and their ability to use it (e.g. running long distances)
• Strength Endurance - a muscle's ability to perform a maximum contraction time after time (e.g. continuous explosive rebounding through an entire basketball game)
• Co-ordination- the ability to integrate the above listed components so that effective movements are achieved.
