TL;DR: Siegel has a gut feeling for dance and a razor-sharp intelligence about it as discussed by the authors, a combination that combines accuracy and imagination, and has enriched our knowledge of the past and added immeasurably, to our resent stock of critical resources.
Abstract: "What is strikingly new about Miss Siegel's achievement is that she goes beyond the usual kind of historical reassessment...She performs on behalf of this most evanescent of the arts an act of significant recovery. By tracking down - often in rare stage revivals, on film or on videotape - as many of the works by major creators of the last half century as survive, and by describing them ...in a manner that combines accuracy and imagination, she has enriched our knowledge of the past and added immeasurably, to our resent stock of critical resources." (Dale Harris, New York Times Book Review). "Siegel has a gut feeling for dance and a razor-sharp intelligence about it. It's an irresistible combination." (Margaret Pierpont, Dance Magazine). "After you've seen and felt dance this deeply--even vicariously--your way of looking at dance will never be the same." (William Albright, Houston Post). "She sees, acutely, with her muscles as well as her eyes. She thinks about dance as much as she experiences it...This is dance choreography reconstituted. Dances leap off the page...The ability to do that is extraordinary." (Jean Bunke, Des Moines Sunday Register). "The sections in which she describes the dances themselves make up the bulk of the book and they are profoundly illuminating...These descriptions represent an amazing literary, as well as critical, accomplishment, for they are both accurate and resonant, both objective and enlightening, both formal and personal." (Laura Shapiro, The Real Paper). "Siegel draws on her years of experience as a working dance critic, a profession she has helped to shape, and brings to a range of American dance a sense of honesty and a mind that wants to understand the antecedents of what is currently in vogue as the dance explosion." (Iris M. Fanger, The Christian Science Monitor).
TL;DR: In this article, the authors investigated the physiological effects of participation in various types of dance programs and found that dance can significantly affect the energy cost of some dance styles, such as tap dance and tap dance.
Abstract: In recent years, dance, in its broadest sense, has been used in many general conditioning and exercise programs Aerobic dance and, more recently, “jazzercise” have become increasingly popular in programs sponsored by YMCAs and recreation departments In addition, the more traditional or established forms of dance, such as ballet, modern, square, social, and folk dance continue to provide recreational activity for people of all agesAlthough there is considerable interest in dance in its many forms, little research has been conducted on the physiological effects of participation in various types of dance programs The energy cost of some dance styles, such as aerobic dance (Igbanugo & Gutin, 1978) and tap dance (Noble & Howley, 1979), have been reported In addition, the heart rate response of college students enrolled in modern dance classes and the beneficial effect of modern dance on sedentary college females have also been investigated (deGuzman, 1979) Recently reported (Rosentswieg & Tate, 1979) was the volumetric determination of the body composition of female dance majors (254% fat), professional dancers (214% fat), and dance educators (183% fat) Also reported in this study was a breakdown of the percent of fat of the professional dancers by style of dance performed: jazz dancers were 23% fat; modern dancers were 198% fat; and ballet dancers were 164% fat Rimmer (1981) reported a mean body density (Db) of 10529 and percent fat of 2013 for a small group of highly trained female dance majors
