group in biofeed lab

Breathing exercises facilitated by biofeedback are used to increase the variability of your hearts rhythm. Increased heart rate variability is associated with a healthier cardiovascular system. These exercises, if practiced regularly, will help you respond to stressors in a healthier way by using breathing as a way to increase parasympathetic drive.

We can also use biofeedback to help you decrease tension in the muscles in your back and neck. These are the muscles that are usually very tense when you are feeling stressed.

Biofeedback Breathing Training

Objective of Biofeedback Breathing Training

Biofeedback training can help teach you how to more effectively respond to stressors in your life. This training helps to increase awareness and control of your mental and physical response to internal and external stressors. This awareness will enable you to control your response to stress just by taking deeper and slower breaths when you feel anxious or afraid.

Objective of the Breathing Technique that We Teach

Resonance breathing training a technique that is used to synchronize your hearts rhythm with your breathing. You can change the variability and dominant rhythm of your heart's activity with practice. Biofeedback equipment gives us a measure of the quality, amplitude and regularity of the variation of your heart's rhythm as well as your respiration pattern. It gives us a measure of synchrony between your cardiac and respiratory system. When you inhale your heart rate should go up, when you exhale your heart rate should slow down.

How Do We Do this Training?

It is very simple, as simple as breathing. Remember when your mom told you, slow down just take a deep breathe. What we are doing is similar, only a little more sophisticated. We will use a pacer to control your breathing rate. It will take few minutes to achieve coherence or synchrony between your breathing pattern and your heart rate. We will practice gradually, beginning at 8 breaths per min, then 7, then 6. We want you to take slow, deep breaths. For most people, the optimum breathing rate will be around 5-7 breaths per minute. With practice it will require less effort and conscious attention.

What Kind of Breathing Technique Should You Practice at Home?

Slow deep breaths like the ones we are doing today for 10 min a day, 2 times a day. We will also give you a hand-out on other techniques that you can practice at home: diaphragmatic breathing; pursed lip breathing; and sustained maximal inspiration. The important thing is to just practice these for a few min, 2 times a day. I think that you will find that you will naturally respond to stressors in your life differently. Rather than allowing your heart rate to accelerate rapidly to a stressor, you will respond by taking slow deep breaths. It is just what mom told you to do.

Cardiorespiratory Laboratory

The Cardiorespiratory Lab is fully equipped for measuring pulmonary function, ventilation, and gas exchange at rest and during exercise in humans. Featured equipment include automated EKG stress testing systems (MedGraphics CardiO2™; Quinton Q Stress and Q4500), radiotelemetry heart rate monitors (Polar), computerized metabolic measurement systems (MedGraphics ULTIMA); EMG equipment (Biopac), Trackmaster treadmill, and cycle ergometers (Lode Excalibur Sport, Corival; Monarch 828E).

Energy Balance & Body Composition Laboratory

The Energy Balance & Body Composition Laboratory contains equipment to assess resting energy expenditure and body composition. The lab is also used for research studies examining various aspects of nutrition and dietary supplementation. In conjunction with the dual-energy x-ray absorptiometry (DXA) scanner contained in the Body Composition Assessment Laboratory, the body composition equipment in the Energy Balance & Body Composition Laboratory can be used to build a 4-compartment model of body composition, the current gold standard method of assessment. This equipment includes several bioimpedance spectroscopy (BIS) and single- and multi-frequency bioelectrical impedance analysis (BIA) devices. Additionally, multiple indirect calorimeters are housed in the laboratory for assessment of resting energy expenditure and substrate utilization. Two computer workstations are also contained in the lab for researcher use.

Human Performance Laboratory

The Human Performance Laboratory is designed for comprehensive mechanical and biophysical analyses of human movement. The lab is equipped with a three-dimensional motion capture system (Vicon Motion Systems, Ltd.), four three-dimensional force platforms (Advanced Mechanical Technology, Inc.; Bertec Corporation), and a wireless electromyography system (Delsys, Inc.) interfaced to a PC equipped for acquiring, processing, and analyzing signals from the laboratory equipment. Specific software suites used in the lab include Vicon Nexus, Visual 3D (C-Motion, Inc.), and MATLAB (The Mathworks, Inc.).

Muscular Assessment Laboratory

The Muscular Assessment Laboratory was designed to allow researchers to study muscle strength and function of the lower body during isokinetic, isometric, and dynamic constant external resistance (DCER) muscle actions. A mobile computer cart with Delsys electromyographic (EMG) equipment is often wheeled in and out of the lab as well. The equipment in the Muscular Assessment Laboratory includes a Biodex isokinetic dynamometer, a custom-built chair designed to measure isometric strength of the leg extensors, and DCER leg extension and curl machines.

Research Intervention Laboratory

Kelsey James and Ahalee Cathey are analyzing the effect of the upright pose training device on (a) standing posture; (b) seated posture while typing on a computer; (c) self-esteem and confidence; and (d) spinal lumbar muscular endurance and fatigue.

Intervention research

The research intervention lab is designed to promote physical health and mental wellness for all people regadless of age, gender or ethnicity through exercise and group mindfulness based activities. These activities include but are not limited to: yoga, pilates, mindfulness, barre exercises, meditation using techniques in pranayama, and resistance training using light weights and balls with an emphasis on posture and alingment. The selected resistance training exercises are designed to increase awareness and to strengthen the body especially the small muscles along the spine in the back recruited during standing posture.

The lab has a wood floor, mirrors, a barre, and a sound system for relaxation training . It is equipped with yoga or pilates mats, balls, light weights, as well as weighted arm and leg velcro cuffs. There are four infinity biofeedback systems and an overhead projector for teaching. A physical therapy table is available for range of motion measurements using a goniometer.

Vascular Assessment Laboratory

The Vascular Assessment Lab is designed to measure vascular function at rest and during exercise in humans. This laboratory uses Doppler ultrasound (GE Vivid 7) and/or strain-gauge plethysmography (Hokanson MD6, E20) to measure skeletal muscle blood flow.  Applanation tonometry (SphygmoCor PVx) is used to estimate aortic blood pressure, measure pressure wave travel, and assess regional arterial stiffness.  Automated blood pressure monitors (CNAP 500at, Omron BP785) and data acquisition systems (PowerLab 8SP) are also employed in this laboratory for research purposes.
