    acids. In general‚ proteins may be structural proteins used to build tissues‚ they may be enzymes that mediate chemical reactions‚ or they may be hormones. Examples of proteins would be channel proteins in cell membranes‚ collagen protein in the skin‚ actin and myosin in the muscles‚ and hemoglobin in red blood cells. Types of dietary sources would be‚ meat‚ milk‚ (both of which are not pure proteins‚ but are good sources of protein)‚ eggs‚ grains and beans. Carbohydrates - Complex carbohydrates

    fascicles. These fascicles are composed of many individual muscle fibers or muscle cells that can be up to several millimeters long. These muscle fibers are composed of myofibrils‚ which are organized into thick filaments‚ myosin‚ and thin filaments‚ actin. These filaments are organized into repeating structures called sarcomeres‚ which are the subunits of skeletal muscle. In order to generate force‚ these filaments must slide past one another (Widmaier 2011). Muscle fibers are innervated by motor neurons

    How exercise affects certain aspects of the body During exercise our body needs more oxygen and blood to keep the muscles activated. To grant this the heart pumps higher frequency of blood increasing the heart rate. Heart pumps blood through arteries faster resulting in a high blood pressure. Exercise increases the stroke volume (the amount of blood pumped in one beat)‚ so an increase in stroke volume means that the heart can pump enough blood to the body with fewer beats per minute. Even after the

    The length-tension relationships represent an important part in the function of skeletal muscle. When skeletal muscle is stimulated‚ passive tissue rapidly changes into dynamic tissue which can produce force. Furthermore‚ during this process‚ the length of muscle may decrease‚ increase‚ or remain the same. Moreover‚ the amount of power a muscle can produce depends on its length‚ velocity and stimulation Powers & Howley (2015). Muscle velocity and stimulation are normally in a constant when creating
