In this study, the test subjects (rats) were fed Jiaogulan for 30 days and subjected to a swimming endurance test. Those subjects given Jiaogulan showed significantly longer swim times and, based on liver glycogen measurements after the swim, were likely to recover faster. This research suggests that Jiaogulan may be beneficial to athletes hoping to improve endurance and excercise recoevery.
