Moral Muscle can be defined as pushing ourselves to do more than the minimum in our moral life. Moral Muscle is not just having physical strength but metal strength. The phrase Moral Muscle is a metaphor in which shows a type of strength someone obtains mentally. Someone who exercises his or her moral muscles has an mindset to do the right thing. Someone is considered to have moral strength when they restrict themselves from doing bad things and in place of that commit good thing. Moral strength

MUSCLE FATIGUE HOW DO MUSCLES GET THE ENERGY TO WORK? In muscles‚ it is essential that Calcium is present‚ as this gives the muscles the ability to contract and relax. For muscles to contract energy is needed: the energy can only be provided by the breakdown of a chemical called adenosine triphosphate (ATP). As ATP is broken down‚ a phosphate molecule is broken off‚ reducing the phosphate molecules‚ from 3 to 2. This produces adenosine triphosphate. However for the muscles contraction to continue

Has to do with the amount of protein and the way it reflects light.

Q1 Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine‚ the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers. Through

1. Discuss the relationship between distribution of muscle fiber type and performance. How might exercise training modify or change a person’s fiber-type distribution? Skeletal muscles contain multiple fiber types that are distinguished by their different myosin ATPase speed‚ and the development of their SR. The two main fiber types are type I and type II fibers. Type II fibers have a faster ATPase and a more developed SR than type I fibers. Type II fibers are also part of a larger motor unit‚

1.1 Glutamine: muscle metabolism Skeletal muscle is the major tissue responsible for glutamine synthesis in the body [9‚10]. In this context‚ glutamine anabolic effects in the skeletal muscle not only preserve lean mass‚ but also maintain plasma glutamine concentration in the body. Glutamine provides energy substrate to cells with a high turnover‚ nucleic acid precursors to cells of the immune system and is involved in the maintenance of acid-base balance [9‚ 11‚ 12]. The key enzymes in the metabolism

Muscle fatigue is weakness or weariness resulting from exertion or prolonged stress and the failure to maintain an expected power output. (Amussen) The process by which your body produces energy is called glycolysis. During glycolysis‚ glycogen is broken to produce creatine phosphate‚ which releases energy. The energy released catalyzes a reaction to produce ATP. The ending product of glycolysis is lactic acid‚ which is created by breaking pyruvate acid down. Then lactic acid is broken down to produce
