This Biopac Student Lab 3.7.5 Lesson 2 script update sets a 60 Hz or 50 Hz Notch filter (based on the Line Frequency setting). The filter is currently set to 0 Hz, which may result in a very “noisy” signal under certain conditions because there is no filter to knock out induced interference from wall power.
To install this updated script:
Download (save) the “L02-EMG-2.zip” file to the desktop.
Extract and open the zipped folder.
Rename the “L02-EMG-2” file to remove the “.dat” extension.

Learn a technique—Trans-radial Electrical Bioimpedance Velocimetry (TREV)—that is more user-friendly and less invasive than the transthoracic method. TREV measures blood movement in the radial and ulnar arteries of the forearm via bioimpedance.
Topics Covered:
– Presentation and discussion of TREV
– Derived Indices Relevant to TREV
– Hardware setup
– Participant setup
– Recognizing good quality and bad quality data
– Demonstration with the grip anticipation test
– Review of results from other tests

Exercise physiology is the study of the body’s response to physical activity. Research in exercise physiology allows for insights in health and for a better understanding of the functions of the body at work. Here are some recent studies in exercise physiology that utilized BIOPAC tools for their research… Effect of exercise on electrocardiographic parameters […]
