I don't guess I've ever thought much about this. I was a gymnast and played football (aka soccer) when I was younger. When I was in my 20s I started practicing yoga and doing martial arts. Looking back when manic I definitely went much harder in sparring when practicing martial arts. I practiced Ninpo Taijutsu, Kali Sikram and Muay Thai. So it was more practical application rather than just doing forms over and over. When I'd be manic I'd be at the gym 6 days a week and go 110% without exhaustion and getting hit during sparring didn't phase me.
