Book Description
ABSTRACT: The purpose of the study was to investigate the relationship between unilateral (UNI) and bilateral (BIL) squat strength and field-based performance tests of sprint speed and change of direction speed (CODS) in Division III team sport athletes. Data was collected from 28 healthy male athletes (19.61 ± 1.07 year, 179.42 ± 4.85 cm, 79.91 ± 10.35 kg). Athletes represented team sports such as football, lacrosse, soccer and baseball. Subjects completed the Pro-agility, 30 m sprint test and 3 RM strength tests unilaterally with the rear foot elevated split squat (RFESS)and bilaterally with front squat, whereby load lifted was used to calculate relative strength ratio. No significant correlation was found between RFESS strength, and CODS or 30m sprint (r = -.255, p > .05, r = -.276, respectively). No significant correlation was found between BIL strength, and CODS or 30 m sprint (r = -.296, p >.05, r = -.349, respectively), although BIL strength produced a moderate to large effective size with the 30 m sprint (r2 = .121). Despite no significant relationships between lower-body strength and field-based performance measures exists, strength and conditioning practitioners should not be discouraged from implementing UNI training with their athletes. The lack of strong relationship between neither BIL or UNI strength and field-based performance measures indicates that neither method is more effective to develop foundations for speed and CODS.

Book Description
The Science of Rugby is the only book to examine the scientific principles underpinning the preparation of rugby players for high performance. Drawing on the very latest scientific evidence, and covering both codes (union and league), the book explores every aspect of preparation and performance that introduces best practice by leading coaches and sports science professionals from around the rugby world. The book covers key topics such as: Physical preparation and conditioning Strength and power training Monitoring match and training demands Match-day strategies for enhancing physical and technical performance Management of fatigue and recovery Training and playing in the heat Travel and jet lag Injury epidemiology Psychological preparation Performance analysis Biomechanics Nutrition Talent identification and youth development The book also incorporates several case-studies to demonstrate how scientific principles have been applied in practice. No other book bridges the gap between theory and applied practice in rugby, from grass roots to elite international standard, and therefore this is essential reading for any student, researcher, sport scientist, coach, physiotherapist or clinician with an interest in the game.

ABSTRACT: The current study was designed to determine the effect of unilateral and bilateral training on soccer performance variables. Subjects included 18 male soccer studentathletes. Five 2 x 2 mixed factorial analyses of variance (ANOVA) were conducted to analyze the data. The dependent variables were 10 m sprint, 40 m sprint, strength, power, and kicking speed. The independent group variable was type of training (unilateral, bilateral) and the repeated measures factor was test occasion (pre, post). Significant main effects for strength and power were observed for the variables of type of training (p = .00; p = .03) and test occasion (p = .00; p = .01). No significant interaction effects were observed for strength or power. The unilateral group had a greater non-significant percent increase in both strength and power. No significant main or interaction effects were found for the dependent variables of 10 m sprint, 40 m sprint, or kicking speed. The 5 weeks of training elicited improvements in strength and power with greater improvements found in unilateral based training.

Book Description
As most other team sports, rugby is a sport of technical finesse, tactical boldness, and refined and complex physical development. In this book, only one, but the crucial element of this sport, will be addressed, namely the physical conditioning. This topic represents the foundation of all the other elements of the game. To make this book very practical and easy to apply, a huge amount of different and important aspects for a good training and the anticipated successes and also specific proposals for the abilities of each position and their development is announced in particular. After a description of the fundamentals of rugby and the general physiological demands of the sport, a player profile is suggested in order to present specific testings and trainings. Also short term and annual training plans are shown and explained in detail to improve the different skills of the players. The most important motor abilities, like power, speed and endurance, have their own chapters, where extra training for them is provided as practical as possible, with many examples and drills. In the end, also the recovery and the nutrition are exactly described, whereby the necessary energy for playing and training is warranted.

Book Description
Rugby Union as a sport has seen continual evolution over the years, and never more so than since the game officially became professional in 1995. While on the pitch tactics have seen more formalized approaches to skill acquisition, it is off the pitch where the biggest changes have occurred and no area has developed more than strength and conditioning. Players have gone from traditionally training for 'fitness' as an add-on to their rugby training to seeking out structured athletic training interventions. Furthermore, with modern rugby players being physically bigger and faster, the need to ensure that they are more robust and free from injury has led to the demand for a more scientific approach to the prescription of strength and conditioning. In Strength and Conditioning for Rugby Union, ex-international player Joel Brannigan presents the underpinning science of strength and conditioning in rugby. Using the fundamental principles of training, he details a structure of assessing rugby players that in turn will allow appropriate training inverventions to be planned out and, most importantly, coached to a wide range of rugby playing levels. Aimed at coaches and players at all levels of the game, sport science support staff, students and academics and fully illustrated with 210 colour images and diagrams.

Book Description
ABSTRACT: The bilateral squat is traditionally chosen as a main lower body exercise in strength and conditioning programs, with unilateral lower body exercises being used as assistance exercises that generally receive less emphasis (McCurdy et al., 2005). Most sport skills, however, such as running, jumping, bounding, and changing direction, are performed unilaterally (Speirs et al., 2016). The purpose of the current study was to determine the relationship between unilateral and bilateral lower body strength and power. Twenty-two NCAA division III football players between the ages of 18-23 participated in the current study. Pearson product moment correlations were conducted to assess the relationship between front squat 1RM and peak power, split squat 1RM and peak power, and front squat 1RM and split squat 1RM. Significant positive linear relationships were found between peak power and front squat 1RM (r = .516, p = .014), peak power and split squat 1RM (r = .451, p = .035) and front squat 1RM and split squat 1RM (r = .778, p

Book Description
The modern game of rugby football has become gladiatorial, whereby muscular athletic players are involved in a form of collision chess with sophisticated defences smothering the offensive skills that were at one time a more dominant feature of the game. The contributors to this book consider the physical, mental and nutritional demands of the game in its present form and how best to acquire these attributes in the most effective and efficient manner. The inevitable injuries that are associated with collision are considered in terms of prevention and the most effective forms of treatment. New concepts to improve exercise capacity, game preparation and recovery are discussed in conjunction with the modern coaching theories of the game. The possible changes to the rules are discussed by two outstanding International referees, and the future vision for World Rugby is outlined by the President of World Rugby. The Dynamics of Modern Rugby is both a unique and contemporary addition to the rugby literature and, as such, is essential reading for any student, researcher, coach, sports scientist, physiotherapist, nutritionist or clinician with an interest in rugby.
