HEALTH AND FITNESS DATABASE -- AEROBICS
Aerobics is a form of exercise that comprises rhythmic aerobic exercise with stretching and strength training routines with the goal of improving all elements of fitness (flexibility, muscular strength, and cardio-vascular fitness). It is usually performed to music in a group setting led by an instructor, although it can be practiced solo and without musical accompaniment. With the goal of preventing physical illness, practitioners go through variable routines comprising a number of different dance-like exercises.
Formal aerobics 'classes' led by aerobics instructors are often divided into beginner, intermediate and advanced classes, with different routines and fitness goals for each, and many aerobics classes allow participants to select their level of participation according to their fitness level. A primary reason for engaging in aerobics is weight loss. Although aerobics is typically practiced to music, it is not to be confused with jazzercise or other dance-based workouts.
The word Aerobics means "using oxygen". When you do an aerobic exercise, like Soccer, basketball, running, or Aerobics, you are breathing. The oxygen passes through your body, as opposed to using up the bodily storage like you do during Sprinting, or bench pressing. Eventually, the muscles are filled with lactic acid, which then takes rest to flush away. The main international governing body for aerobics is the Féderation International de Gymnastique, based in Liège, Belgium.[citation needed] It was formed in 1881. Italian Bruno Gandi is the current president.
Aerobic exercise gets the heart working to pump blood through the heart more quickly and with more force than normal. As blood is pumped faster, it must be oxygenated more quickly, which quickens respiration. Aerobic exercise strengthens the heart and boosts healthy cholestrol levels. Low impact aerobics include walking and swimming. Running, tennis and dance are high impact aerobics.
