In addition, they have been effective for improving jump height in soccer, volleyball, and basketball.</p><p><strong>Methods: </strong>The effects of the 11+ Dance, a dance-specific neuromuscular warm-up program, was examined on jump height and lower extremity biomechanics during bilateral and single leg countermovement jumps in recreational dancers. Twenty female adolescents from 2 dance schools participated in this 2-centered 8-week controlled non-randomized trial. The intervention group (IG) performed the 11+ Dance program 3×/week for 8-weeks during the first 30-minute of their regularly scheduled dance classes. The control group (CG) continued with their regular dance classes routine.

However, no statistical between group differences were observed (<i>Z</i> = 0.38-1.22, <i>P</i> > .05).

The rest of the book is divided into parts—“Individual Differences” (chapters on personality, perfectionism, self-esteem and self-confidence, and anxiety), “Dance-specific Characteristics and Dispositions” (chapters on motivation, attentional focus, and creativity), “Psychological Skills” (chapters on mindfulness, goal setting and self-regulation, and imagery), and “Dance Environments and Challenges” (chapters on motivational climates, talent, injury, and body image and disordered eating). Each chapter contains introductory material that describes terms, concepts, and principles, followed by specific cases and applications. The writing is clear, well-referenced, and exceptionally well organized. Chapters lead with an inspirational quote, a list of chapter objectives and key terms, and conclude with key points and recommendations, and critical aspects of research on the topics in the chapter. In the text, Nordin-Bates offers not just basic principles from cognitive behavioral therapy or techniques (such as functional analysis, in querying, say, why a dancer might be performing better during a stage performance than in practice), but also, critical thinking. These include possibilities for using dance psychology in one’s practice or ways in which one can return faster and stronger from injury or learn from queries about the nature and impact on performance of personality in dance. The author notes which chapters have more dance-specific references, for example, chapters on psychological aspects of injury correlated to body image and disordered eating, and those with less (chapters on goal setting). Nordin-Bates argues that dance psychology is not a tack-on to sports psychology, but a field of study in its own right, even though there are common topics of concern (perfectionism, confidence, anxiety, and so on). The book’s discussions are enlightening: Why punishment is counterproductive (being also inefficient and abusive), how personalities naturally develop over time and how we can change them, performance-related consequences of perfectionism, and perfectionism management techniques—what dancers can do, what teachers can do, and when to seek professional help. The practicalities and applications are here, too—ways to strengthen self-confidence (which may include designing exercises that allow dancers to feel satisfied with their accomplishments and effort), and reduce somatic symptoms of anxiety with breathing, relaxation, exercise, and music techniques.
