ABSTRACT
This chapter aims to contribute to an understanding of the complex interaction between mind and body and sports, exercise, and physical fitness. To that end psychological theories, research, and experimentation are involved in presenting a thesis that a certain admixture of sports exercise and physical fitness will affect maturity. The features and functions that can be directly observable and those of neurons, hormones, chemistry, genetics, and actions of the various systems are designated as body functions. The study of motivation in human behavior has much broader application than sports, on a slightly broad perspective, exercise and physical fitness, and at the broadest level, all aspects of human endeavor. Psychoanalytic theory is given some words of mention in a number of volumes that deal with motivation and touched upon in some sport psychology books.
