ABSTRACT
Performance is not just a matter of level of performance, nor does it just depend on body condition: it is also a matter of contingencies that function as context for the performance. Sometimes the person will think the body change is for the better, and sometimes regret the changes but weigh the loss in the balance of doing better in the chosen activity. An impaired heart may prevent someone from climbing a hill or traveling to the mountains, but leave quite untouched most everyday actions at home, at work, at play. Self-challenges in performance extend to what can be termed “body projects.” These are attempts to do better not only with the body but to the body. An impaired heart may prevent someone from climbing a hill or traveling to the mountains, but leave quite untouched most everyday actions at home, at work, at play.
