1] Fitness - Physical fitness is defined as 'The ability to carry out daily tasks with vigor and alertness,without undue fatigue,and with ample energy to enjoy leisure -time pursuits and responds to emergencies'.

in order to complete all of the tasks ,one must consistently address their fitness levels.This requires proper conditioning through both structured exercise and leisurely activities.

components of fitness- depending on the source ,the components are

• Cardiorespiratory endurance - Typically measured by how long or fast a person can perform an activity & how this impacts measurements such as heart rate and oxygen consumption.
• Muscular endurance- typically measured by how many repetitions of an exercise a person can perform.common tests involve push-ups and sit ups.
• Muscular power- Typically measured by how much force can be generated during a given activity.Advanced equipment used by biomechanists are often needed to measure muscular power.
• Flexibility - Typically measured by how how far a muscle group can be streched or joint can be moved.
• Balance - Typically measured by how long a particular position can be held with or without some type of activity being performed.simple tests such as standing on one leg can be used to assess balance.
• Speed - Typically measured by how quickely an individual can move from one point to another.
• Body composition -this is the amount of fat on the body verusu other tissues such as muscle,bones and skin.measured using a variety of tests using mathematical equations.
