Biofeedback: Can you Teach your Body to lose Stress?

Thursday, October 20th, 2011

Here is a great article from CNN related to biofeedback. Dr Gevirtz, Leherer and Peper offer their insight into how biofeedback and proper breathing (taught via biofeedback) can be used to reduce stress.

Biofeedback: Can you Teach your Body to lose Stress?

When it comes to stress relief methods for me, the devil is in the execution. More likely than not, I will stack whatever it is (or an article or book about it) on my bedside table and expect it to sink in through magic and osmosis. Alas …

I got a call early last week from my friend Parvathi, who works for a Washington clinical psychologist specializing in cognitive therapy for patients with anxiety and obsessive-compulsive disorder. “You need to check out some of these biofeedback devices for stress,” she said. “My doctor has a few of them in the office. He lends them out to patients who are having anxiety.”

I was skeptical. When I actually saw a picture of one of them, the question was obvious: How do you reduce stress by sticking your finger into a socket thingy and breathing for a while?

“Biofeedback is remarkable,” said Erik Peper, a San Francisco State University professor who has been involved in self-regulation and stress management for decades as both a teacher and a clinician.

He proceeded to lead me through a 30-second breathing exercise on the phone that left me lightheaded. “You see? Even small changes in your breathing can make a significant difference in your physiology — in your body, mind and emotions.”

Biofeedback in Sports

Wednesday, February 9th, 2011

Biofeedback training has been widely recognized as an excellent way to promote a relaxed state for many sports applications. Many studies have been done on using biofeedback as a method of relaxation and to increase performance.

Athletes should ask themselves “Can I perform better in a relaxed state?” If it is the bottom of the ninth, with the bases loaded, the athlete needs to be able to clear their mind and focus on the performance. Anxiety and high stress can cause many athletes to “choke” in clutch situations. By learning to alter their mental and physiological state with a few simple relaxation techniques they tend to perform better. Biofeedback devices are great tools in achieving these results.

There have been several Olympic athletes, NHL hockey teams, professional football teams, golfers and more, that have credited biofeedback training as a factor in their success.

In a recent chat with Thought Technology Vice President Lawrence Klein, he could not resist the opportunity to discuss the many uses of his company’s biofeedback and neurofeedback equipment. Mr. Klein said, “We have a strong presence in professional and elite sports.” Thought Technology’s equipment has been used by a number of leading Olympic Sport Coaches and several professional sports teams.

Some teams have even set up mental training centers where trainers monitor the brainwaves and other physical functions such as surface EMG, temperature, GSR, heart rate, and respiration. This helps the players learn to reduce performance anxiety and improve their ability to focus under stress – giving them the “mental edge” they need to win.

There are devices like the Resperate, that promote meditative breathing patterns and very simple to use items such as the GSR2, that measures minute changes in skin conductance or resistance and conveys the stress level by an audio tone. These devices are easy to use and very effective. Organizations and teams have also used more sophisticated systems that measure multiple physiological measurements at once for a picture of the body’s stress level.

More recently there are products being introduced to help speed up reaction time. Reaction time can be crucial in many sporting events and in the Olympics millisecond can be the difference between gold and bronze.

Below are a couple of videos about biofeedback and athletic performance.

What is Respiratory Sinus Arrhythmia (RSA)?

Tuesday, June 3rd, 2003

RSA is the natural cycle of arrhythmia that occurs through the influence of breathing on the flow of sympathetic and vagus impulses to the sinoatrial node.

The rhythm of the heart is primarily under the control of the vagus nerve, which inhibits heart rate and the force of contraction. When we inhale, the vagus nerve activity is impeded and heart rate begins to increase. When we exhale this pattern is reversed. The degree of fluctuation in heart rate is also controlled significantly by regular impulses from the baroreceptors (pressure sensors) in the aorta and carotid arteries. When RSA is enhanced through biofeedback, the goal is usually to reinforce the natural feedback activity of the baroreceptors through our breathing pattern.
