A reason for this is a change in mood state. This link between exercise and mood has been noted in the sports psychology and exercise literature and I wanted to share one or two points I came across.
- Rhythmic abdominal breathing: Both aerobic and anaerobic can be useful here. (Previously only the former was seen, as beneficial). This means thinks like Tai Chi swimming and yoga count here ! The particular juru, that I use, emphasises breaking in for some moves and out for other moves. This may explain why I feel better in my solo training. The rhythmic effect of the breathing is at play. (NB not much in the Wing Chun literature emphasises breathing patterns during the forms. One notable exception if Randy Williams' work - he does place emphasis on this in his videos, I recall).
- Rhythmic and repetitive movements. This is tied to the above as well. It is obvious forms and jurus rely on this. My book says this frees the mind to focus on more important issues - but I am not totally sure I do this in forms. Although, going for a 'walk in the rain', is often an activity cited when inverters have eureka moments. The rain clears the air from dust and maybe purer oxygen gets to the brain ? (Same in the shower ?).
- Closed and predicable activities : where the environment is controllable (in the exercise activity) distractions can be ruled out and you have control over your circumstances. You can pace yourself. The jurus are contained activities and no novelty enters into this. 116 movements too on the dummy - same thing. No novelty involved in that cycle of rhythmic repetition.
