Yadav, G., Mutha, P. Deep Breathing Practice Facilitates Retention of Newly Learned Motor Skills. Sci Rep 6, 37069 (2016).
THE BIG DEAL
How you breathe after you train a new motor skill affects how well you stay good at the thing you just learned and practiced physically, e.g. virtuosic passages on a musical instrument, moves in a martial art or techniques in sport, etc.
WHY IT MATTERS
Recovery is a fundamental aspect of the performance cycle. Activating the parasympathetic nervous system to encode these new neural pathways is an art unto itself.
Discerning and implementing an appropriate breathing protocol, as usual, is a fundamental component of high performance. In this case, the authors focus on a 30-minute session of deep (open to interpretation) alternate-nostril breathing. This would clearly work, as would other, arguably equally if not more effective, methods such as XPT Balance Breathing and Cadence Breathing. As always, proper and functional breathing with optimal biomechanics will dictate the efficacy of the practice.
