The accompanying graph relates to the abundance of ocean life (productivity) in a polar region of the Northern Hemisphere. Exercise in warm temperatures or for an extended period of time, Increased sweating, breathing,and muscle contraction results in loss of water, Water loss results in decreased blood plasma and thickening of theblood, Decreased blood plasma results in decreased in venous return, Decreased venous return results in decreased stroke volume, Decreased stroke volume results in decreased cardiac output, The heart compensates by increasing heart rate. government site. Unauthorized use of these marks is strictly prohibited. A reduction in hydration results in a decrease in blood volume and pressure, which results in cells becoming more concentrated and the kidneys not functioning effectively (decreased filtration). Cardiovascular Drift and Why Hydration is key to Sports Performance. This is for two reasons. The rise in cardiac output is a result of a rise in heart rate and stroke volume and the subsequent plateau is a result of an appropriate supply of oxygen to sustain the metabolic demands of the physical activity. Compared to static or dynamic resistance exercise, aerobic exercise demands an increase in energy and therefore an increase in oxygen (hence aerobic exercise).
