Intensive training produces remarkable changes in the cardiovascular system. There are two general types of intensive training: endurance training, and strength training. Endurance training is based on developing moderate effort for a long time, improving the capacity of the aerobic system. In strength training, very intense efforts are developed for a short time, stimulating muscle development and anaerobic metabolism. The effects of training on the cardiovascular system are diverse, and would depend on its type, intensity, and duration.
