VENTURA, Calif., Feb. 15 /PRNewswire/ -- The assessment of physiological
mood shifts among athletes during a competitive virtual reality environment
will be tracked and evaluated by researchers at Saint Anselm College in
Manchester, New Hampshire, using the LifeShirt System from VivoMetrics(R). The
LifeShirt, a non-invasive, light weight garment used to monitor respiratory
and cardiopulmonary function, will enable researchers to help establish how
mood affects athletic performance.
A total of 23 participants, including 17 college varsity athletes wore the
LifeShirt in a virtual reality scenario. The virtual environment included a
headset which projected a visual representation of a running track while the
athlete ran on an elliptical machine. When participants started running on a
virtual track and reached a 60-70% maximum heart rate on the third lap, a
virtual competitor appeared on the track stimulating a self reported
frustration as the athlete was required not to increase work load, rather let
the competitor stay ahead of them on the track. The LifeShirt was then used to
record variations in heart rate and respiration, known as additional heart
rate, to determine how competitors may affect the physiological responding of
an athlete who self reports frustration during competition.
"Previously clinical researchers used physiological monitoring equipment
to monitor mood assessment and performance but the equipment limited
participants to a sedentary position," said Dr. Finn PhD, a key researcher in
the study and professor of Psychology at Saint Anselm College. "With the
LifeShirt, for the first time, we can monitor how positive or negative stimuli
affect the athlete as he performs."
The study began in the fall 2004 and will conclude in spring 2005. Key
findings and final results will be available in May 2005.

About the LifeShirt System
The LifeShirt System is the first non-invasive, ambulatory monitoring
system that continuously collects, records and analyzes a broad range of
cardiopulmonary parameters. Users wear a lightweight, machine washable garment
with embedded sensors that collect pulmonary, cardiac, posture and activity
signals. Data collected by integrated peripheral devices measure blood
pressure, blood oxygen saturation, EEG/EOG, periodic leg movement,
temperature, end tidal CO2 and cough. An electronic diary captures subjective
user input and all physiologic and subject data are correlated over time. The
LifeShirt System has received FDA clearance and EMEA approval (CE Mark).
VivoMetrics, founded in 1999, provides ambulatory monitoring products and
services for the collection, analysis and reporting of subject-specific
physiologic data. Pharmaceutical companies use VivoMetrics' technologies to
improve the speed and economics of clinical research. The company's offerings
also enable academic researchers to discover new clinical signatures of
disease, and U.S. Government agencies to protect the lives of military and
civilian first responders.
