Wearable | Visualizing Exercise
Scientists have long used the power of physiological signals to make inferences about cognitive processes. To bridge the gap between physiology and psychology, exercise scientists often find it interesting to look at a person’s encephalographic brain frequencies (EEG) during settings of physical stress, or namely, exercise. Several studies in the past have aimed to evaluate how the mind operates during strenuous training, but what happens when someone just thinks about exercising?
Researchers Berk et al. have recently performed a study in which various athletes were asked to simply sit, close their eyes, and visualize themselves in a state of rest while their brains were monitored for EEG activity. Participants then were asked to visualize themselves in a state of heavy exercise or physical training. The researchers monitored the athletes’ brain EEG signals using a B-Alert X10 Telemetry system. What they found was a significant difference in brain state, primarily shown by the disparity in gamma wave frequency between visualizations of exercise and rest settings. These results suggest that mental visualization of complex physical tasks may support the construction of functional neural networks in the brain necessary for performing them. This study opens the door to subsequent research in order to understand more about the psychology of physical activity. BIOPAC Systems offers the wireless B-Alert X10 EEG system as well as other wearable and wireless solutions for psychophysiological and exercise research. These options include Mobita 32 channel wearable EEG and biopotential systems and the BioNomadix line of wireless biopotential and transducer amplifiers. These products have been consistently proven to provide accurate, reliable data whether the person wearing them is on the field training, or sitting at home just thinking about it.
Logging Physiological Data | Data Acquisition
Logging subject
data has never been easier than with the advent of wireless subject recording
devices. Quality wireless products allow for accurate readings on a subject’s
physiology in ways tethered devices cannot. Now with products like the Mobita
wearable biopotential system, data logging is simpler than ever before. Mobita
is a physiological signal amplifier system that can record up to 32 channels of
high-fidelity wireless biopotential data, including ECG, EEG, EGG, EMG, and EOG
data. The Mobita also contains an onboard accelerometer that allows for, along
with AcqKnowledge’s Actigraphy feature, evaluation of a subject’s
activity levels.
Together with AcqKnowledge software, the system can be
quickly configured to do the work of multiple systems without the added cost of
multiple amplifiers. Simply disconnect one header and
snap on a new configuration for a completely different application. The
system has the option to either log data locally for later download or
telemeter back to a computer running AcqKnowledge for real-time display.
The Mobita can easily switch between either live or logged mode to suit your
research protocol. Using the built-in WiFi telemetry allows for a wide range of
mobile subject recordings. The system has flash disk recording for up to 16 GB
allowing large chunks of data to be stored and kept for back-up. Mobita is also
a very flexible, wearable system due to its technical power and small size. Don’t let the system’s small size and rechargeable battery power operation fool
you—the Mobita has the power to record up to 32 channels at up to 2K s/s and is
fully integrated with AcqKnowledge. The system features a rugged
construction making it well suited for tough and demanding measurement
situations. The Mobita system is sturdy, dustproof, and most importantly is
kept safe in its waterproof enclosure. The Mobita is the premier wireless
biopotential system that is uniquely suited for a variety of applications such
as psychology, neuromarketing, sports, ambulatory testing, and many more. See
