Electromyography (EMG) Comparison of Four Different Back Extension Devices
According to Dreisinger & Nelson (1996), roughly 80 percent of U.S. adults will experience low back pain at some point in their lives, with many of them expected to have recurring bouts (Anderson, 1999). In response to this pandemic, numerous fitness equipment manufacturers have developed devices to help strengthen specific musculature in an effort to prevent or recover from chronic low back pain. The purpose of this study was to compare four different variants of back extension devices to see which best targets the low back musculature. Researchers hypothesized that the 90-degree back extension would illicit the greatest peak activation of the longissimus as well as the lowest peak activation of the biceps femoris due to the unique positioning of the body for that respective device.
