Dimic, M., Furuya, R. “…The decision of how the body weight will be distributed at the time of the landing presents the crucial decision for the split step efficiency at the landing sequence (Melvill-Jones & Watt 1971; Lees 1981; McNitt-Gray 1993) METHODS: We observed the split step performance of two expert players, Federer and Djokovic, at the Wimbledon finals match. …”

Bayle, E. “…This observation is reflected in two major phases of its development: the "Chatrier revolution" (1968-1992) and the "period of maturity" (1993-2020). These relationships have led to a governance of compromise to anchor a development strategy aimed at optimizing and legitimizing public support. …”

Raue, C., Dreiskämper, D., Strauß, B. “…Shared Mental Models (SMM) are defined as knowledge structures held by each team member, enabling them to form accurate explanations and expectations of each other and adapt their own behavior (Cannon-Bowers et al., 1993). So far, measurements captured SMMusing statical questionnaires (e.g. …”

Haudum, J., Wagner, H., Schwameder, H. “…Bewegungen in bzw. über Schulterhöhe erzeugen oft Schmerzen und werden im Alltag von Rollstuhlfahrern wenn möglich vermieden (Burnham, May, Nelson, Steadward & Reid, 1993; Finley et al., 2004). Rückenmarksverletzungen könnten daher dazu führen, dass Tennisspieler, die im Rollstuhl sitzen, ihre Schlagtechnik entsprechend ihrer Verletzung verändern. …”

Bastiaens, K., Müller, M., Braun, D., Nafzieger, D., Ferrauti, A. “…One exercise method is to use heavy loads to induce recruitment of high-threshold fast Type II motor units by the size principle (Sale, 1987), and another method is to use light loads to maintain the specificity of the exercise velocity and to maximise the mechanical power output (Wilson, Newton, Murphy & Humphries, 1993). Studies with load controlled velocity training show that the speed at which an individual trains, results in a velocity specific change in muscle activation (McBride et al., 2002). …”

Blank, P., Eskofier, B. M. “…Diese hochdynamische Sportart und ihre Vielzahl unterschiedlicher Spielvariationen (Hodges, 1993) macht Tischtennis zu einem komplexen und damit herausfordernden Sport, nicht nur für Spieler selbst, sondern auch im Bereich der Datenauswertung und Spielanalyse. …”

Mavvidis, A., Maier, P., Koranis, F. “…Es ist bekannt, dass für die Entwicklung des Tennisellenbogens sowohl eine Muskelermüdung im Armbereich (Stratford et al., 1993; Vincencino et al., 1996; 1998; Pienimatiki et al., 1997) als auch eine gewisse Bewegung verantwortlich sind. …”

Faber, I. R., Nijhuis-van der Sanden, M. W. G., Oosterveld, F. G. J. “…TID often contain tests to assess specific sport skills in athletes which are considered to be key-predictors for success (Régnier et al., 1993). In this context, valid and reliable tests are essential to obtain trustworthy results. …”

Jaitner, T., Gawin, W. “…Spitzenathleten erreichen dabei Ballfluggeschwindigkeiten von ca. 80 m/s und mehr (Kollath et al., 1986; Lee, 1993; Tsai & Chang, 1998). Als dominierendem Element im Badmintonspiel kommt dieser Schlagtechnik eine spielentscheidende Rolle zu. …”

Panjan, A., Sarabon, N., Filipic, A. “…The analysis included altogether 1,002 male and female tennis players who had undergone regular testing by the National Tennis Association and were positioned on the ranking list of the Slovene Tennis Association between the years 1993 and 2008. Selections of the most promising variables by means of the two automatic methods yielded similar results, whereas the selection performed on the basis of estimates made by coaches differed considerably. …”

Hohmann, A., Zhang, H. “…The purpose of this paper is to show how the concept of performance diagnosis by mathematical simulation (Lames 1991; Perl, 1993) can be transferred to table tennis. According to that concept, the series of the interactive game actions (e.g. serve, return, offense, defense, and so on) can be described by means of a statistical transition matrix between the different states of action. …”

Jackson, R. C., Gudgeon, M. “…Specifically, it has been suggested that anticipation may largely be learned implicitly, that is, experts may become sensitive to subtle postural cues or situational probabilities without necessarily intending to do so and in such a way that the resulting knowledge is difficult to express (Berry & Dienes, Implicit learning : Theoretical and empirical issues, 1993, Hove : Lawrence Erlbaum Associates). Thus far, there is no clear evidence of implicit learning in the anticipation literature, therefore, the aim of the present study was to examine whether implicit learning of a serve location sequence would occur in tennis players. …”

Tiniakos, G.-A. “…Die sportmedizinischen Untersuchungen zur Ermittlung der körperlichen Leistungsfähigkeit, der kardiozirkulatorischen Leistungs- und Erholungsfähigkeit sowie der metabolischen Parameter von 61 SportlerInnen 49 männlich und 12 weiblich aus Zypern fanden im Zeitraum vom 23.1.1993 - 31.1.1993 in Nikosia, Zypern statt. Die erwähnten SportlerInnen wurden fahrradergometrisch im Sitzen nach der 1 Watt / kg-Methode erschöpfend ausbelastet und anschließend die 5-minütige Erholung beobachtet und registriert. …”

Katsagolis, A., Zarotis, G., Koronas, K., Mandis, K., Karagiani, O. “…The suitability of young athletes for competitive sports and their athletic orientation are the basic questions which experts have tried to answer (Schmindt, R. 1993, Gould 1987, Singer & Gerson 1978). Many researches have been held by tennis experts (Bos, K. & Wolhmenn, R. 1990, Kohler, K. 1977, Koizner, K. 1987, Katsagolis, A 1992) sup-porting the idea that the natural and empirical choice of young tennis players has to begin at the age 6-8 and the pro-fessional selection after the completion of the 8th year of training. …”

Mantis, K., Mavridis, T., Antoniou, P. “…The questionnaire (CSAI-2; Martens, Burton, Vealey, Bump & Smith, 1990) was translated and adapted into Greek by Kakkos and Zervas, 1993. The results indicated that the interference and existence of precompetition state anxiety was significant in the female badminton athletes (p< 0.01). …”

Mitchell, S. R., Jones, R. L., King, M., Kotze, J. “…Brody (1979, 1987, 1997), Elliot (1982), Liu (1983), Hatze (1993), Cross (1997)]. A heavier racket with a higher moment of inertia is harder to swing and should result in lower head speeds or greater effort to achieve the same speed. …”
