The muscular system allows the body to move voluntarily, but it also controls involuntary movements of other organ systems such as heartbeat in the circulatory system and peristaltic waves in the digestive system. It consists of over six hundred skeletal muscles, as well as the heart muscle, the smooth muscles that surround your entire alimentary canal, and all your arterial blood vessels see Figure 2. Muscle contraction relies on energy delivery to the muscle. Each movement uses up cellular energy, and without an adequate energy supply, muscle function suffers. Muscle, like the liver, can store the energy from glucose in the large polymeric molecule glycogen. But unlike the liver, muscles use up all of their own stored energy and do not export it to other organs in the body. Muscle is not as susceptible to low levels of blood glucose as the brain because it will readily use alternate fuels such as fatty acids and protein to produce cellular energy. Chapter 2.

Balance Studies. Are you ready?. Holmes M. In contrast, an analysis of the Framingham Heart Study Offspring Cohort shows an inverse association between dietary protein intake and inflammation and oxidative stress scores, derived from measures of nine inflammatory biomarkers [ 59 ]. Skeletal muscle protein is dynamic and in constant flux, alternating between states of negative i. Low protein diets are also associated with decreased intestinal calcium absorption and an increase in the levels of the key bone regulatory hormone parathyroid hormone. Tomatoes : Have 4 chambers like the heart. More energy is required to break down fats and proteins than carbohydrates; however, all excess calories that are ingested will be stored as fat in the body. Ingested protein dose response of muscle and albumin protein synthesis after resistance exercise in young men. This will help reduce your risk for injuring your muscles or joints. Therefore, hypervitaminosis of water-soluble vitamins rarely occurs, except with an excess of vitamin supplements.
