    Respiratory sinus arrhythmia is part of the autonomic nervous system and serves to optimize gas exchange between the lungs and the circulatory system. It was measured through an electrocardiogram (ECG) and included respiratory sinus arrhythmia at rest, during orthostatic stress, and during the Spatial Orienting Task and Bangor Gambling Task.

    Blood pressure is the force of blood pushing against the walls of arteries as the heart pumps blood around the body. Systolic pressure is the pressure when the heart contracts and pushes blood out and diastolic pressure is the pressure when the heart relaxes and fills with blood. In adults, the systolic pressure normally ranges between 80 and 120 and the...

    The Tanner Scale describes, both pictorially and descriptively, the external changes that occur in the time period between the onset of puberty and the achievement of full maturity for both girls and boys. Characterizations of pubertal status are assessed by breast development in girls, genital development in boys and pubic hair growth in both. The Tanner...

    Skinfold thickness is an assessment of body fat which can noninvasively and reliably be measured at various sites of the body using a skinfold caliper. Based on measurements at multiple sites of the body, the total body fat and contribution of fat to the body mass can be estimated.

    The pre-ejection period (PEP) as measured through Impedance Cardiography (ICG) is the time interval between the electrical stimulation of the ventricles and the opening of the aortic valve. Variables include the pre-ejection period at rest, during orthostatic stress, and during the Spatial Orienting Task, Bangor Gambling Task, and Trier Social Stress Test.
