Purists may tell you that combining cardio and strength training just won't work, or creating interval training from ordinary workouts is a waste of time. But athletes who prepare for actual sports - not aesthetic Speedo comparisons up on a stage - know that this is one of the most effective ways not only to gain size, but to gain strength, agility, balance, and performance.
Interval training is a way to work both the aerobic and the anaerobic systems within the body at the same time. It's an obvious time-saving tool, but also a valuable training tool that nets more calories burned and provides more intensity than most know how to inject into workouts.
For example, during a high intensity effort, or sprint, the anaerobic system uses the energy stored in the muscles (glycogen) for short bursts of activity. Since anaerobic metabolism works without oxygen, the by-product of that kind of workout is lactic acid. (That's the burn you feel when you're tired from lifting).
Also during high intensity intervals, when lactic acid builds, an athlete enters oxygen debt. During a recovery phase, heart and lungs work in tandem to recover this oxygen debt and breaks down lactic acid built up through the sprint activity. camisetas de futbol oficiales , It is in this phase that the aerobic system is in control, because it uses oxygen to convert stored carbohydrates into energy.

Alternating between these forms takes care of the lactic acid from both phases and allows you to continue to build up endurance and strength, based on the activity and recovery cycles of each, opposing one another.
This repetitive form of training leads to the adaptation response. camisetas futbol 2011 , The body begins to build new capillaries, and is better able to take in and deliver oxygen to the working muscles. Muscles develop a higher tolerance to the build-up of lactic acid, and the heart muscle is strengthened. These changes result in improved performance particularly within the cardiovascular system, but it also benefits the musculoskeletal system in terms of overall density and size.
