Answer 1

Answer:

Physical fitness is the state of being physically healthy. The person must be fit to perform the concerned sport or occupation. Physical fitness can be achieved through correct nutrition, regular exercises, and proper rest or sleep. The components of physical fitness are:

Muscular Strength: Muscular strength has many definitions. Most commonly it is defined as the ability of a muscle to lift the weight. It may also be defined as the amount of force your muscles can exert on an object during anaerobic activities that are in absence of oxygen gas. In the scientific form, muscular strength is the ability of cells to supply the muscle fibre with muscle energy in the form of adenosine triphosphate (ATP) for muscle contractions. There are three classes of muscular strength:

Maximum Strength: It is defined as the greatest force a person or the muscle can apply in a single maximum contraction.

Elastic Strength: It is defined as the capability to overcome resistance with a fast contraction.

Strength Endurance: It is defined as the ability to exert force many times.

Without muscular strength, the body will become weak. The person may not be able to perform his daily routines in the absence of muscular strength. Muscular strength can be achieved by lifting heavy weights.

Muscular Endurance: In simple language, muscular endurance is the ability to perform exercises in a repeated fashion without getting tired. Muscular strength deals with activities which cause short duration muscle contractions while muscular endurance includes the activities which cause muscle contraction in a sustained manner. The muscles are not used for a few seconds but for a few minutes. Muscular endurance is important for the cardiovascular system.
