83 for this type of injury, tolerance is an important factor to consider. In this study, naproxen sodium did not produce any side-effects whereas three patients treated with piroxicam developed adverse reactions. Both naproxen sodium and piroxicam have been shown to be effective in treating acute traumatic injuries. Naproxen sodium was better tolerated and led to the early cure of a greater number of patients. RE FERENCES Abbott, C. J. A., Bouchier-Hayes, T. A. I., Hunt, H.

BOOK REVIEW Title: PHYSIOLOGICAL TESTING OF THE ELITE ATHLETE Editors: J. Duncan MacDougall, Howard A. Wenger and Howard J. Green Publishers: Canadian Association of Sports Sciences in collaboration with the Sports Medicine Council of Canada Price: $30 181 pages The Canadian physiologists I have met in conferences over the last ten years are enthusiastic, highly capable, individuals. They share the same concern as British physiologists with reference to quality control in testing of elite athletes. In collaboration with the Sports Medicine Council of Canada, the Canadian Association of Sports Sciences, have produced a manual which deals specifically with physiological testing. The manual devotes a chapter to the evaluation of Strength, Flexibility, Aerobic Power, Anaerobic Power, Body Composition and Anthropometry. Each chapter includes the rationale for testing the physiological component discussed, its relevance to particular sports, the validity and reliability of the testing procedures and guidelines for interpreting the results. Generally the book is well written, with rationale and methodology dearly defined. in particular, I thought the chapters on Aerobic Power, Anaerobic Power and Kinanthropometry provided essential information with reference to technical laboratory measurement. The Strength chapter was also well written, with perhaps a little too much emphasis on the use of the Cybex machine, which unfortunately is not a feature of British laboratories. Flexibility is always an enigma in the physiological profile of an athlete and the authors, discussing this topic, tended to confirm this without any further enlightenment. The chapter on the Health Status of the Athlete emphasises the need for medical back-up in the testing of elite athletes. The authors of this manual are knowledgeable scientists with considerable practical experience in the laboratory testing of athletes. This is a useful publication that has highlighted the need for quality control and discussion with reference to athletic testing. It is well referenced and recommended reading for personnel involved in athletic monitoring. B Bruce Davies copyright. on February 22, 2022 by guest.
