They practice proper exercise technique and form. They learn how to combine aerobic and anaerobic techniques. Basic interval training consists of high or low cardiovascular or aerobics movements, including step training, and resistance exercises performed in an alternating fashion. The movement speed is alternately increased and decreased, using both the aerobic and anaerobic systems. There are a number of benefits this type of training produces.
Interval training optimizes the development of cardiorespiratory fitness.
The muscles develop a higher anaerobic threshold with a greater tolerance to lactic acid, producing the ability to exercise faster and longer. The fast twitch muscle fibers responsible for speed become tuned up and ready to go. The number of blood vessels in the muscles increase allowing a greater oxygen supply. Interval training also provides variety and a time efficient workout. The components of interval training are Work Intervals and Recovery Intervals.
