Pilates and the “powerhouse”—I

Abstract

Abstract The Pilates method is a comprehensive body-conditioning method that is directed toward the development of both the body and the mind of the individual. Toward this end, the Pilates method incorporates six key principles: centering, concentration, control, precision, breath, and flow. The purpose of this paper is to investigate the underlying biomechanical foundation of the principle of centering. The principle of centering refers to the concept that all movements of the human body emanate from the center or core or what Joseph Pilates called the powerhouse of the body. The Pilates method endeavors to strengthen the powerhouse as one of its primary goals. In effect, strengthening the powerhouse is core-stabilization. Part one of this article investigates what the boundaries and components of the powerhouse are as well as the muscle groups that effect movements of the powerhouse. It then explores the three major effects that Pilates exercises have upon the health and integrity of the powerhouse: (1) its effect upon pelvic posture, (2) its effect of lengthening the spine, and (3) its effect upon the structural integrity or tone of the abdominopelvic cavity. The sum total of these effects is to create what may be termed the Pilates Powerhouse Posture . Part two will then illustrate various Pilates exercises and describe their effects upon the powerhouse.
