“…Sport psychology is in many ways a comprehensive scientific field as it provides an arena for studying the interaction of human performance, thoughts and emotions (Singh et al, 2009 ). However, the sub-field of ski jumping research is small, with only a few research groups focusing on biomechanical, physiological, and aerodynamically related aspects for optimal ski jumping performance (e.g., Virmavirta and Komi, 1993 ; Komi and Virmavirta, 2000 ; Ettema et al, 2005 ; Schwameder, 2008 ). Thus, there is by the authors knowledge no research on the psychological and emotional aspects of world class ski jumping performance that has been published.…”

Self-Efficacy, Flow, Affect, Worry and Performance in Elite World Cup Ski Jumping

The present study investigated the relationship between self-efficacy, flow, positive- and negative affect, worry and ski jumping performance, as well as the degree of influence these psychological factors have on ski jumping performance in specific competitions and overall World Cup ranking. World Cup ski jumpers (N = 40) responded to four questionnaires in the middle of the World Cup season, reporting their subjective experience during a competitive setting over a period of three consecutive days. Social Cognitive Theory (SCT) and Flow Theory was used as main conceptual frameworks. Self-efficacy was moderately related to ski jumping performance, both overall World Cup ranking (r = −0.37) and the results from the first out of three individual ski flying competitions (r = −0.36) and explained approximately 14% of the variance in the overall World Cup. Flow was moderately related to ski jumping performance, both overall World Cup ranking (Flow-Focus) (r = −0.34), and individual ski flying results from the first competition (Flow-Arousal) (r = −0.36). The Flow-Arousal explained approximately 13% of the variance in ski flying results. Worry was highly related to ski jumping performance in the second (r = 0.60) and third (r = 0.52) competition, indicating that approximately 36 and 27% of the variance in ski flying results could be accounted for by levels of worry, respectively. Negative affect was moderately related to ski flying performance (r = 0.34). These results show that psychological factors that regulate emotional states may be of importance for World Cup ski jumping performance, and that appropriate coping strategies, constructive mindset and motivation, appears to be essential in this regard. To our knowledge, this is the first study on the relationship between these psychological factors and ski jumping performance among World Cup athletes. The study adds important information about some of the dynamic features of emotional and psychological mechanisms involved during elite ski jumping performance.

“…The take-off velocity on the hill, composed of the in-run velocity and the vertical take-off velocity, reaches its peak approximately 0.3 seconds after the beginning of the take off ( 17 , 23 , 28 , 42 ). The explosive strength needed for a large vertical component of the take-off velocity is especially important on smaller hills with jump distances of less than 95 minutes ( 6 ), where a high rate of force development increases the take-off velocity ( 31 ).…”

Pauli, CA, Keller, M, Ammann, F, Hübner, K, Lindorfer, J, Taylor, WR, and Lorenzetti, S. Kinematics and kinetics of squats, drop jumps and imitation jumps of ski jumpers. J Strength Cond Res 30(3): 643–652, 2016—Squats, drop jumps, and imitation jumps are commonly used training exercises in ski jumping to enhance maximum force, explosive force, and sport-specific skills. The purpose of this study was to evaluate the kinetics and kinematics of training exercises in ski jumping and to find objective parameters in training exercises that most correlate with the competition performance of ski jumpers. To this end, barbell squats, drop jumps, and imitation jumps were measured in a laboratory environment for 10 elite ski jumpers. Force and motion data were captured, and the influence of maximum vertical force, force difference, vertical take-off velocity, knee moments, knee joint power, and a knee valgus/varus index was evaluated and correlated with their season jump performance. The results indicate that, especially for the imitation jumps, a good correlation exists between the vertical take-off velocity and the personal jump performance on the hill (R = 0.718). Importantly, however, the more the athletes tended toward a valgus knee alignment during the measured movements, the worse their performance (R = 0.729 imitation jumps; R = 0.685 squats). Although an evaluation of the athletes' lower limb alignment during competitive jumping on the hill is still required, these preliminary data suggest that performance training should additionally concentrate on improving knee alignment to increase ski jumping performance.

“…Resultados semelhantes são descritos por ELLIOT & BLANKSBY (1979) e MERO, KOMI &GREGOR (1992).A ausência de atividade de um músculo extensor, como é o m. vastus lateralis, justamente na fase de extensão do segmento no qual atua não deixa de ser um fato surpreendente. Ainda que não exista uma resposta definitiva para este paradoxo, diversos autores sugerem que o mecanismo de acúmulo e restituição de energia elástica pelos músculos esqueléticos seriam a explicação mais lógica para o comportamento exibido não somente pelo m. vastus lateralis, como também por grande parte dos músculos extensores que atuam no membro inferior(KOMI, 1980(KOMI, , 1992MERO & KOMI, 1987).O m. gastrocnemius mantém-se ativo durante grande parte da fase de contato. Na fase inicial do apoio sua atividade objetiva a desaceleração horizontal da perna por intermédio de uma ação excêntrica.…”

Foram muitos os amigos que me acompanharam nestes últimos anos.Apenas as palavras não podem expressar a importância dessas pessoas no transcorrer dessa longa jornada. Impossível agradecer por tudo que fizeram por mim.Que Deus os abençoe. Minha eterna gratidão a meus pais Carlos e Ivete Serrão, meu irmão Carlos, e minha avó Francisca Cerca, não somente pelo imenso esforço que fizeram para que eu pudesse chegar até aqui, mas principalmente pelo amor que sempre tiveram por mim. Um especial agradecimento a meu avô, Aristides Cerca, que infelizmente se foi antes que esta etapa tivesse chegado ao fim. Sua bondade e seu amor deixaram muita saudade, e a eterna gratidão por ter convivido-com uma pessoa tão especial. A minha esposa Ana Cláudia, que apesar de ter sido privada de muitas horas da merecida atenção nestes últimos anos de trabalho, nunca deixou de ser a pessoa maravilhosa por quem me apaixonei. A minha amada filha Fernanda, cujo sorriso é a maior inspiração da minha vida. A esta família tão amada devo tudo que sou. Neste tempo em que os exemplos são cada vez mais raros, agradeço ao Prof. Alberto Carlos Amadio pelos constantes exemplos de integridade, dedicação, competência, e sobretudo pela amizade. Sua orientação e apoio constituíram os alicerces que estruturam minha vida acadêmica. Agradeço ainda aos amigos Bruno
