Bethesda, MD 20894, Web Policies The smaller chamber of the heart, which has thinner muscular walls. The cardiovascular system consists of the heart and blood vessels. This has a knock-on effect if the aim of a specific training session is to be exercising in a specific heart rate zone or window. Cardiovascular drift, the progressive increase in heart rate and decrease in stroke volume that begins after approximately 10 min of prolonged moderate-intensity exercise, is associated with decreased maximal oxygen uptake, particularly during heat stress. Circulation , 122, S706 - S719.
