ESSENTIALS OF STRENGTH TRAINING AND CONDITIONING MULTIMEDIA SYMPOSIUM Presentation 5: Measurement and Evaluation by: Andrew Fry, PhD, CSCS NSCA Certification Commission® 3333 Landmark Circle ● Lincoln, NE 68504 ● 402-476-6669 ● 888-746-2378 ● commission@nsca-cc.org ● www.nsca-cc.org Measurement and Evaluation Presentation 5 MULTIMEDIA SYMPOSIUM OVERVIEW This multimedia symposium was developed for the specific purpose of providing individuals who sit for the Certified Strength and Conditioning Specialist® (CSCS®) certification exam with a review of facts, concepts, and theories that are relevant to strength training and conditioning. You are encouraged to simultaneously listen and watch the symposium video presentation, view the PowerPoint® slide show, follow along in the presentation outline, and add your own notes in the spaces within the outline (more paper may be necessary). To maximize the value of the multimedia symposium when preparing for the CSCS exam, you may find it helpful to first study the Essentials of Strength Training and Conditioning (2nd edition) text. Further, candidates who perform well on the CSCS exam typically have considerable practical experience in strength training and conditioning athletes (e.g., designing programs, teaching proper exercise technique, performing testing sessions) and a strong academic background in the exercise sciences (i.e., anatomy, physiology, biomechanics, etc.). For additional suggestions for preparing for the CSCS exam, go to www.nsca-cc.org. NOTICE: • Although this presentation was recorded live and then professionally edited for scope and length, there are some room sounds, voice fluctuations, abrupt video “cuts” and piecing of video clips, and content variations. Every possible effort was made to minimize these irregularities. • All of the content of the multimedia symposium is protected by copyright. No part of the multimedia symposium may be reproduced or transmitted (in part or in full) by any means or in any form, electronic or mechanical, including digital copying or recording, or via any information retrieval system, including internet and intranet communications, without permission in writing from the NSCA Certification Commission. • While comprehension of the information provided by the multimedia symposium should certainly increase the likelihood of passing the CSCS certification exam, it does not guarantee a successful performance. The questions on the CSCS exam are developed from numerous resources in addition to the multimedia symposium. ©2006 NSCA Certification Commission Page 2 Measurement and Evaluation I. II.
