Exercise -purposeful physical activity that is planned, structured, and repetitive and that improves or maintains personal fitness Aerobic: aka Cardio, with oxygen. You are working your heart and lungs while exercising your muscles. Should be 20-60 minutes long three to five days a week. Anaerobic: without oxygen. Exercise that causes you to get out of breath quickly. Examples would be weightlifting or sprinting. Cardiovascular System -body system that includes the heart, blood vessels, and blood, and functions by carrying oxygen and nutrients to cells and removing cell wastes Heart Rate -the number of times the heart beats per minute Max Heart Rate: is the maximum number of times your heart should beat per minute while doing any physical activity. 220-AGE=Max HR Endurance: Trains your heart to pump more blood to muscles and your muscles to extract more oxygen more efficiently Interval Training: alternating cycles of high intensity and rest or low intensity exercises. Aerobic Capacity - the maximal amount of exercise or or work that an individual can do measured by oxygen consumption. Aerobic capacity- the maximal amount of exercise or or work that an individual can do measured by oxygen consumption. Cardiorespiratory Endurance -the ability of the heart, lungs, and blood vessels to use and send fuel and oxygen to the body’s tissues during long periods of moderate-to-vigorous activity Flexibility -the ability to move the joints through a full range of motion Exercise Stages:

Diet -a selection of foods Caloric Expenditures -the amount of calories used during daily activities and exercise Calorie -a unit of energy found in food
Run -to move swiftly on foot so that both feet leave the ground during each stride. Ball of foot touches ground first; arms move opposite legs. Skip -step-hop. Hop on left foot, right leg bent and lift into the air, land on right foot, left leg bent and lift into the air, continue pattern Slide -stand with shoulder facing the wall, right foot extends to the side away from body and left foot crosses mid- plane toward right foot. Side-together. Jog -a slow steady run Jump -to take off using two feet and land using one or two fee PACER -stands for Progressive Aerobic Cardiovascular Endurance Run and is a test for cardiovascular fitness Plyometric exercise- a rapid powerful movement preceded by a preloading counter movement which creates a stretch-shortened cycle of the muscle.
Nervous System -body’s control center and communications network; it consists of the brain, spinal cord, and nerves Respiratory System -brings oxygen in and lets carbon dioxide out of the body Skeletal System -gives your body shape and support, provides protection for vital organs, and produces blood cells Core muscles- these are the abdominal, back, hip, and pelvic floor muscles Veins -blood vessels that return blood back to the heart Circulatory -the heart and the system of blood vessels in the body, including the arteries, capillaries, and veins Circulatory System -is your body’s internal transport system which moves blood through the body Cardiovascular System -body system that includes the heart, blood vessels, and blood, and functions by carrying oxygen and nutrients to cells and removing cell wastes Muscular System -accounts for all of the ways that the parts of the body move, protects joints, and helps create heat to keep body warm Muscular Endurance- the ability of the muscles to perform physical tasks over a period of time without becoming fatigued Muscular Strength -the amount of force a muscle can exert Lymph -the clear, yellowish fluid that leaks from capillaries, fills the spaces around the body’s cells, and is collected by the lymphatic vessels and nodes Lymphatic System -a network of vessels that carry a clear fluid called lymph throughout the body
