or this one:
But does it really work?
That is a question my colleague Kathy Little and I posed in our paper “Two studies of Superbrain Yoga’s potential effect on academic performance based on the Number Facility Test.”
Here is the abstract:
“Superbrain Yoga is an exercise that involves squatting while holding the ear lobes with controlled breathing. Advocates claim that this exercise improves cognition and academic performance. This study tested the ability of Superbrain Yoga to improve performance on a cognitive task called the Number Facility Test. In the first experiment, 30 adults completed a baseline version of the Number Facility Test; performed standard squats, Superbrain Yoga, and a rest trial (counterbalanced); and were re-administered the Number Facility Test after each task. A nonparametric Quade test showed no significant difference in outcome measures (p = .99, Kendall’s W = .005). In the second experiment, 30 adults completed a baseline version of the Number Facility Test, performed standard squats and 2 alternative forms of Superbrain Yoga (counterbalanced), and were re-administered the Number Facility Test after each task. A Quade test indicated no significant difference in outcome measures (p = .19, Kendall’s W = .086). These results provide no support for the claims made for Superbrain Yoga. However, this research cannot exclude the possibility that alternative forms of Superbrain Yoga might be effective or that it might have an effect on cognitive skills not captured by the Number Facility Test.”
