“Meditation provides an atmosphere of deep relaxation beneficial to the mind and body, offering myriad physiological effects such as lower blood pressure and a slower heart rate. When the body is extremely relaxed, the mind, nerves and muscles work at an optimum level, allowing for the enhancement of a variety of motor performance skills.” – EOC Institute
When most people think of memory they think of verbal memory or episodic memory. They rarely think about motor memory. But, this is a very import facet of human behavior. If they do think of motor memory they usually think of athletic performance. This is indeed a motor memory but is the tip of the proverbial iceberg. In fact, the bulk of our behavior from walking to talking involves motor memory. The memories there are so deep that we are generally not aware of them. But pay attention for a moment to the movements involved when you’re walking and you’ll see just how automatized it is, just how much it’s a learned behavior that is stored in motor memory.
The process by which what we have learned motorically is transferred to a long-term storage is called consolidation. This process is poorly understood. But, it is known that consolidation works best when there are no competing memories produced shortly after the primary memory. So, rest and even sleep, appear to promote the consolidation of motor memory. Mindfulness training has been shown to improve verbal memory ability. But, little is known regarding the effects of mindfulness practice on motor memory or motor memory consolidation.
The ability of meditation to influence the consolidation of motor memory was explored in today’s Research News article “Post-training Meditation Promotes Motor Memory Consolidation.” See:

Immink recruited practiced meditators (between 2 to 25 years of practice, mean = 9 years) and had them learn to press a set of six keys in three unique sequences. Repeated over 120 trials. This was completed at 8:00 in the morning. The participants were then randomly assigned to either a 30-minute yoga nidra meditation condition or a light work (chores) condition that was conducted at noon. At 5:00 in the afternoon participants were tested for performance of the three learned sequences and two new sequence that they had not been previously trained on. They were measured for errors, reaction time to start the sequence and time to complete it.
During motor training the two groups did not differ in the number of errors committed, reaction time, and time to complete the sequence. During later testing, the participants who meditated at noon were significantly faster in reacting to and performing the previously learned sequences than the control group but did not differ with the new (untrained) sequences. Hence, meditation appeared to specifically help preserve the previous motor learning, while not affecting new learning. In fact, the meditation group did not lose any speed between training and testing while the control group was 35% slower.
These are clear and interesting results. They suggest that meditation promotes the consolidation of motor memories, that is, it tended to protect the memories from deterioration over time. So, mindfulness training appears to promote both verbal and motor memory. This might suggest that meditation might be helpful in preserving all kinds of other motor memories including athletic performance and perhaps physical therapy. It will require further research to examine these speculations.
So, consolidate motor memories with mindfulness.
“Meditation in sport is not only helpful for performance, but can also aid athletes who experience anxiety, depression, and other mental health illnesses. The practice can help athletes through injury, as well as overcome challenges such as the transition back into sport or out of sport (e.g., retirement).” – Kristin Keim

Study Summary
Immink MA (2016) Post-training Meditation Promotes Motor Memory Consolidation. Front. Psychol. 7:1698. doi: 10.3389/fpsyg.2016.01698
Following training, motor memory consolidation is thought to involve either memory stabilization or off-line learning processes. The extent to which memory stabilization or off-line learning relies on post-training wakeful periods or sleep is not clear and thus, novel research approaches are needed to further explore the conditions that promote motor memory consolidation. The present experiment represents the first empirical test of meditation as potential facilitator of motor memory consolidation. Twelve adult residents of a yoga center with a mean of 9 years meditation experience were trained on a sequence key pressing task. Three hours after training, the meditation group completed a 30 min session of yoga nidra meditation while a control group completed 30 min of light work duties. A wakeful period of 4.5 h followed meditation after which participants completed a test involving both trained and untrained sequences. Training performance did not significantly differ between groups. Comparison of group performance at test, revealed a performance benefit of post-training meditation but this was limited to trained sequences only. That the post-training meditation performance benefit was specific to trained sequences is consistent with the notion of meditation promoting motor memory consolidation as opposed to general motor task performance benefits from meditation. Further, post-training meditation appears to have promoted motor memory stabilization as opposed to off-line learning. These findings represent the first demonstration of meditation related motor memory consolidation and are consistent with a growing body of literature demonstrating the benefits of meditation for cognitive function, including memory.
