Demonstration

Demonstration of the use of a Metabolic Cart during Exercise        
Drew Bois, Alison Stanlewicz, Victoria Vargas

Metabolic carts are used to measure the specific amount of oxygen consumed (VO2), carbon dioxide production (VCO2), and other key other ventilatory variables while performing maximal or submaximal exercises. The study of these ventilatory behaviors during exercise adds valuable information with regards to energy expenditure, exercise intensity, aerobic fitness levels, and severity of some diseases, functional cardiovascular and respiratory capacities, and mortality rates. Therefore, information obtained through this equipment is fundamental to allow researchers to understand underlying mechanisms controlling and regulating the interactive responses of the cardiovascular and respiratory systems during exercise challenges. The main objective of this laboratory demonstration is to show in real time how VO2 and VCO2 responses behave during an exercise challenge. Specifically, a volunteer within the Cardiovascular Dynamics Laboratory research group will demonstrate how a metabolic cart is used to assess VO2 and VCO2 responses during treadmill walking and running in different intensities. Upon completion of the demonstration, it is expected that the audience will gain a better understanding of the ability of the cardiovascular and respiratory responses to adapt to different exercise stimulus as well as how exercise physiologists use various apparatuses to study these physiological responses.

Demonstration of the anaerobic power and anaerobic capacity use a Wingate
Kevin Rivera, Devin Neary, Stephanie Priest

The main objective of this laboratory demonstration is to show in real time how to assess peak anaerobic power, anaerobic capacity, and fatigue index using the Wingate Anaerobic Test. A volunteer within the Cardiovascular Dynamics Laboratory research group will perform the Wingate Anaerobic Test. Prior to the test a low resistance warm-up will be performed for approximately 5 minutes in order to minimize the risk of injury. The test will be performed using a mechanical cycle ergometer with the individual pedaling for 30 seconds as fast as possible with workload representing 0.7% of individual’s body weight. The number of revolutions will be recorded every 5 seconds during the test. After test, volunteer will be pedaling against low resistance in a cool-down phase. Peak power, relative peak power, anaerobic capacity, and anaerobic fatigue index will be determined based on the Wingate anaerobic test results. Upon completion of the demonstration, it is expected that the audience will gain a better understanding of the ability of the body to perform maximal performance using anaerobic metabolism to attend the high intensity exercise demand.

Demonstration of the use of an Electrocardiogram during Exercise
Ingrid Vanessa Monzon

Electrocardiogram (EKG) allow measurements of the heart electrical activity every beat using electrodes placed on the skin in the chest of a person. The heart of a healthy person depolarizes progressively in order to ensure that the heart pump blood efficiently every heart contraction. This depolarization sequence is responsible for the characteristics of the EKG tracing. The EKG provides fundamental information about the structure and function of the heart electrical conduction system. The EKG can be used to measure rate and rhythm of the heartbeats as well as size and position of the heart chambers. During exercise, EKG tracing can be used to understand normal and abnormal responses that can be seen only during exercise. The main objective of this laboratory demonstration is to show in real time how EKG tracing and specifically heart rate behave during an exercise challenge. Specifically, a volunteer within the Cardiovascular Dynamics Laboratory research group will demonstrate how an EKG is used to assess heart rate responses during treadmill walking and running in different intensities. After demonstration, it is expected that the audience will gain a better understanding how heart rate adapts to different exercise intensities.
