Physiology relates to the functions and homeostasis in the structural organization of an organism. For an athlete it is important to keep fit because the performance is based on the condition of his or her body. Therefore, for the best performance possible, their dynamic state of equilibrium requires proper maintenance. Since in the body, various organ systems are interdependent but require cooperation of other systems to work, they are made up of organs that work together closely. These organs are then further classified into different types of tissues with a common function including epithelial tissues, connective tissues, Nervous tissues, and muscle tissues. Of these tissues, the muscle tissues are composed of cells or fibers that contract …show more content…
For instance, cardiac muscle tissues which are only found in the heart are striated with one nucleus per cell. They are involuntary muscles and they have intercalated discs which allow the heart to contract. Like cardiac muscle tissues, skeletal muscle tissues are composed of striated tissues. However, they contain multiple nuclei and are usually connected to either or both extremities with a bone serve to move bones and the body. They are voluntary muscles which contain a lot of mitochondria. They are striated and have a long cylindrical shape. Skeletal muscle helps to maintain posture, stabilize joints and generate heat. Unlike skeletal muscles, smooth muscle tissues are smooth non-tubular (spindle-like) muscles that control slow involuntary movements. They are found in the walls of hollow organs and contain a single nucleus therefore they can function in digestive organs. Skeletal muscles have functions such as excitability, contractility, extensibility, and elasticity. This means that they are accountable for responsiveness and have the ability to receive and respond to stimuli. This also means that the muscle can shorten, lengthen or recoil based on the action …show more content…
Furthermore, synergists are helpers of prime movers and occur during flexors while fixators keep the body stable during movement and maintain posture. For the 100 meter dash, the fixators are the fingers placed on the floor while crouched. The levers are the arm bones and the leg bones (humerus, radius, tibia, femur, etc) while the load is the athletes body. There are multiple points that can be said to be the fulcrum and effort but focusing on the knees and ankles, the movement will involve the athlete’s dominant leg or the push-off leg. For this movement, the effort will be in the leg muscles (including the thigh muscles) and this will involve the use of a second or third class
