Association Between Mental Imagery and Change of Direction Performance in Young Elite Soccer Players of Different Maturity Status
Abstract: Previous studies have not considered the potential influence of maturity status on the relationship between mental imagery and change of direction (CoD) speed in youth soccer. Accordingly, this cross-sectional study examined the association between mental imagery and CoD performance in young elite soccer players of different maturity status. Forty young male soccer players, aged 10-17 years, were assigned into two groups according to their predicted age at peak height velocity (PHV) (Pre-PHV; n = 20 and Post-PHV; n = 20). Participants were evaluated on soccer-specific tests of CoD with (CoDBall-15m) and without (CoD-15m) the ball. Participants completed the movement imagery questionnaire (MIQ) with the three- dimensional structure, internal visual imagery (IVI), external visual imagery (EVI), as well as kinesthetic imagery (KI). The Post-PHV players achieved significantly better results than Pre-PHV in EVI (ES = 1.58, large; p
Change-of-direction Performance in Elite Soccer Players: Preliminary Analysis According to Their Playing Positions
Abstract: Our objective was to examine the relationship between change of direction (CoD) performance, with (CoDb), and without the ball (CoDwb), and selected measures of physical fitness (jump performance, speed, balance) in elite soccer players, according to players' positions. Forty elite male soccer players performed the change-of-direction and acceleration test (CODAT) with (CODATb), and without the ball (CODATwb), 5- and 20-m sprint tests, the 5-jump test (5JT), and the Y-balance test (YBT). Analyses of the whole sample showed significant correlations between all CODAT measures (CODATwb and CODATb, respectively) and sprint 5-m (r = 0.72, p
The Effects of Different Rehabilitation Training Modalities on Isokinetic Muscle Function and Male Athletes' Psychological Status After Anterior Cruciate Ligament Reconstructions
Abstract: Background Previously, researchers reported performance enhancements following long-term plyometric training in athletes with anterior cruciate ligament reconstruction (LCA). However, the effects of combined eccentric and plyometric training on measures of isokinetic strength and psychological statues in male athletes have not been examined yet. Knowledge on the effects of combined eccentric and plyometric training help to better plan and program rehabilitations sessions and thus return-to-sports. Objective This study sought to compare the effects of three different rehabilitation training programs, eccentric training (ECC), plyometric training (PLYO), or combined eccentric and ply...
Sport Imagery Questionnaire
Imagery, in today's world of sport psychology, is as vital and fundamental a part of an athlete's mental game plan as the physical training required for conditioning. With a widespread embrace of such a philosophy comes new ways to analyse and measure its performance among athletes. In 'The Sport Imagery Questionnaire: Test Manual' the authors assess athletes' use of imagery by proposing and outlining a specifically designed evaluation of its effectiveness, the Sport Imagery Questionnaire (SIQ). The Manual is designed for sport psychologists, coaches, athletes, or anyone who seeks to understand or quantify the use of mental imagery in sport. Features: A 4-page reproduction of the Sport Imagery Questionnaire in an easy-to-photocopy format, complete with instructions and specific rating chart; A 'Scoring the SIQ' section to calculate imagery performance; A brief overview of the SIQ clearly and explicitly outlining its purpose and function; 3 comprehensive chapters dedicated to understanding imagery, explaining the methods involved in both developing and successfully utilising the SIQ, and the psychometric properties and normative data of the questionnaire itself.
Imagery in Sport
It has long been known that almost all elite athletes use imagery and that most sport psychologists apply imagery in working with athletes. But most material on the subject has been, to this point, relegated to single chapters in books, to journal articles, or to conference proceedings. Now Imagery in Sport addresses the breadth of what researchers and practitioners in sport psychology know about the topic, and it treats each issue in depth, considering current theories and research on imagery and its application in sport. The reference also addresses future directions in research and practice for imagery in sport. In doing so, Imagery in Sport provides the most comprehensive look at the sta...
Agility in Sport
This book introduces a new view of agility theory, given recent serious discussion concerning the methods of open-loop skills improvement. It offers experimental research results and theoretical knowledge on both reactive and running types of agility. The book also details a number of agility training methods and exercises.
Neuromuscular Training and Adaptations in Youth Athletes
The Frontiers Research Topic entitled "Neuromuscular Training and Adaptations in Youth Athletes" contains one editorial and 22 articles in the form of original work, narrative and systematic reviews and meta-analyses. From a performance and health-related standpoint, neuromuscular training stimulates young athletes' physical development and it builds a strong foundation for later success as an elite athlete. The 22 articles provide current scientific knowledge on the effectiveness of neuromuscular training in young athletes.
The Role of Physical Fitness on Cardiovascular Responses to Stress
Cardiovascular responses to physical and/ or mental stressors has been a topic of great interest for some time. For example, significant changes of cardiovascular control and reactivity have been highlighted as important mechanisms for the protective effect of exercise as a simple and effective, non medical therapy for many pathologies. However, despite the great number of studies performed to date (e.g. >54,000 entries in Pubmed for “cardiovascular stress”), important questions of the role stress has on cardiovascular function still remain. For instance, What factors account for the different cardiovascular responses between mental and physical stressors? How do these different componen...
