%X Physiological changes in musculature allow widespread movements in human body. Correspondingly, varying in muscle prototypes characterise direct different training paradigms in therapeutics practice or can governs athletic performances. Mode of muscle contraction type are isometric, concentric or eccentric. Great examples of concentric exercise are walking- up-hill, stair ascent and lifting a dumbbell in bicep curl or pushing a bar up. Examples of eccentric muscle actions are walking - down-hill, satire decent and, isokinetic arm and leg extensions. During isometric muscle contraction the length of muscle does not change while muscle exert force .This type of movement can be seen while a person performs a maximal voluntary contractions (MVCs).Eccentric exercises increasing the concentric and isometric contraction as well. Performing the eccentric muscle contraction in daily life enhance quality of life and lifespan due to increasing muscle strength with low cost of energy consuming and thus it can apply in variety of domains. A simple walking task such as downhill - walking (i.e. 30 min) can provide the aforementioned conditions. DOI10.14302/issn.2578-8590.ipj-18-2441 Investigations of the skeletal muscle structure and function refer to the the Renaissance period in the history1. This early observation has become the foundations of the physiology and clinical approaches in modern era2. Virtually, all movements including any obvious or subtle movements result from muscle contractions. The integrations of the skeletal ¨C muscle and associated joints fulfil large motions such as in walking and running while move body around delicately in different position or posture3. Dynamic skeletal muscle plasticity allows widespread movements in human body4. Untypical muscles have ability to uniquely contract, lengthen or shorten to generate motions. Nonetheless, muscle types differ in functional structure and capability, so that various muscles executed deliver different movement loads depending on the features and characteristics5,6. Correspondingly, varying in muscle prototypes characterise the physical strength physiology in human body. Physiological changesin musculature strength can influence the movement performances in different areas. Skeletal muscle in fact is a regulatory property of exercise regimes in different areas. Diverse properties of human skeletal muscle can direct different training paradigms in therapeutics practice or can governs athletic performances. In this relation, it is shown that eccentric muscle contraction enhance muscle strength and in
