PMC Engaging in moderate-to-vigorous intensity physical activity (MVPA) is important for protecting cardiovascular health among women in midlife (i.e., ages 40-60)-particularly if they have already developed conditions that increase their risk for cardiovascular disease (e.g., hypertension). Cardiac output can be expressed by the below formula: Cardiac output = stroke volume (SV) X heart rate (HR). Approximately how much fluid per hour exercise should someone consume? As little as a 1.5 % loss in hydration is classed as dehydration, which is referred to as an excessive loss of water from the body. What environment is needed for cardiovascular drift to occur? What reduces during cardiovascular drift? Cardiac output is the product of stroke volume and heart rate. It is therefore important that this fluid loss is replaced.
