Book Description
PURPOSE: Previous studies have examined the relationship lower-body strength and power has with performance in events that require change of direction (COD). However, there is a scarcity of investigations which have considered the influence strength and power have on the magnitude of improvement in COD performance as a result of training. Moreover, interventions selected within the literature are often not representative of interventions used by strength and conditioning professionals. Therefore, the purpose of this study was to investigate the relationship between strength and power and the magnitude of improvement in COD as a result of training. METHODS: Eleven collegiate athletes (age = 20.55 ± 1.214 yr; height = 186.52 ± 6.569 cm; mass = 108.76 ± 17.433 kg) from a Division II American football program participated in the study. Subjects were pre and posttested in vertical jump (VJ), standing broad jump (SBJ), peak force (PF), time to peak force (TPF), rate of force development (RFD), one-repetition maximum back squat (1-RM BS), hexagon test, pro agility test, and T -test. Both absolute values along with data normalized to body mass were used for purposes of comparison. Subjects participated in an 8 week training program designed to increase strength, power, and COD. Tests used to assess COD during pre and posttesting were not used during the intervention. RESULTS: Pretest VJ power showed strong correlation with both absolute change and percent improvement in the T-test (r = -0.59 · and -0.58, respectively). A strong correlation was also found between the absolute change in SBl and the absolute change in the hexagon test (r = -0.51). Pretest ReI PF showed strong correlation with both pro-agility and the T -test (r = -0.5 and -0.58, respectively). Pretest TPF and the hexagon test showed strong correlation (r = -0.S1) as did ReI 1-RM BS and the T-test (r = -0.54). Poshest ReI PF revealed strong association with both the pro agility test and the T-test (r = -0.61 and -0.81, respectively) and Rel 1-RM BS showed strong correlation with performance in the T -test (r = -0.6). CONCLUSION: The findings of this investigation suggest that an athlete's ability to express strength and power may influence subsequent adaptation to interventions designed to improve COD. Moreover, adaptations in strength and power may also influence the magnitude of Improvement in COD tasks. PRACTICAL APPLICATION: Practitioners may wish to consider sequencing their training to focus on strength and power early in the athlete development process in order to enhance potential adaptations in COD later on in training. In addition, when considering the addition of COD to the training plan, it may be appropriate to maintain focus on increasing strength and power. Key words: COD, power, isometric strength, dynamic strength, American football.

Editor Todd Miller and an authoritative team of contributors have compiled an exceptional reference and valuable tool for practicing professionals and an indispensable educational resource for students. NSCA's Guide to Tests and Assessments presents the latest research from respected scientists and practitioners in exercise testing and assessment. The text begins with an introduction to testing, data analysis, and formulating conclusions. It then features a by-chapter presentation of tests and assessments for body composition, heart rate and blood pressure, metabolic rate, aerobic power, lactate threshold, muscular strength, muscular endurance, power, speed and agility, mobility, and balance and stability. Using descriptions of multiple test options for each key fitness component, readers will learn to choose from a range of alternatives to meet the needs of their athletes, reach training objectives, choose from available equipment, and work within budgets. Each chapter provides a summary detailing the key testing and assessment information for each fitness component, the equipment needed for performing the tests, step-by-step instructions, normative data for the tests, and multiple test options per conditioning component. Insights into the applications of testing for certain fitness components are also presented: • The value of body composition assessments in determining health and fitness levels for competitive athletes as well as individuals across the life span • How an understanding of 24-hour energy expenditure can be useful in structuring a complete diet and exercise plan for weight loss, gain, or maintenance • How to select a maximal or submaximal aerobic power test that is specific to the demands of a client’s or athlete’s sport • Discussion of the mechanical and physiological factors shown to influence the expression of muscular strength • An examination of the relevant factors influencing power production and explosive movement capacity • Differences between mobility and flexibility and a discussion of the acute versus chronic effects of static stretching • Theories and concepts of balance and stability, their effects on performance, and categories of testing for balance and stability NSCA's Guide to Tests and Assessments also includes NSCA-approved testing protocols, extensive references to current research, and applications for the testing of conditioning components. Information is presented in an accessible manner to help explain the findings of both researchers and practitioners so that readers can select the most effective and efficient approach for athlete and client assessments. Properly conducted tests and skillful assessment of data enable fitness professionals to develop individualized training programs based on their clients’ or athletes’ physiological and functional capacities. Credible, current, and complete, NSCA's Guide to Tests and Assessments provides a clear understanding of the test selection process, how to implement appropriate data collection, and how to analyze data to make appropriate training decisions that will help athletes and clients achieve their performance goals. NSCA’s Guide to Tests and Assessments is part of the Science of Strength and Conditioning series. Developed with the expertise of the National Strength and Conditioning Association (NSCA), this series of texts provides the guidelines for converting scientific research into practical application.

Book Description
Strength and power are recognised as key components of human health and performance. Therefore, it is vital for exercise scientists and strength and conditioning practitioners to be able to assess these qualities effectively. Testing methods of these components are often presented as standalone chapters in textbooks which provides the reader with an overview of these aspects. Testing and Evaluation of Strength and Power provides a detailed explanation of testing and evaluation methods for strength and power. The book considers the relationship between the methods of assessment, research on the various approaches to evaluation and how practitioners and researchers can use the information in applied settings. The book provides the reader with a comprehensive overview of methods of strength and power assessment protocols and how they can be used to inform programming. This integrated approach to assessment of strength and power is recommended reading for students on strength and conditioning course and of vital reading to those on specialised courses on strength and power as well as coaches in the fitness testing and strength and conditioning disciplines.

Book Description
Women's sport in general has gained an increasingly higher profile and level of respect in recent years, and it is becoming widely acknowledged that a female athlete's training programmes will differ in several respects from that of their male counterparts. Despite this, there is a dearth of research evidence available to coaches and athletes to guide the planning and programming process, with limited comparisons of training adaptations between the genders and in particular, a lack of investigation into elite female performers. Strength and Conditioning for Female Athletes contains insights from various experts in this specialised area. This text outlines specifically what is and what isn't known regarding female athlete development, and exposes the gaps that currently exist in the academic literature, with practical examples of applied practice. Coaches, sports scientists and athletes themselves will find here a wealth of useful information, with topics including: needs analysis; programme design for the basic biomotor abilities; speed and agility; long-term athlete development; the menstrual cycle and gender-specific injuries.
