The purpose of this study was to investigate the effects of receiver′s moving speed and distance on passer′s movement planning(estimated RT), movement time, and ultimately on temporal accuracy(absolute error) of passed ball. Sixteen subjects(eight novice and eight expert) were required to make a total of 30 passes in coincidence with an experimentally manipulated moving light signal in randomly presented six different conditions, i.e., in three differing light speed(1.5m/s; 3.0m/s; 4.5m/s) and in two differing moving distance(2m or 4m). Results of analyses showed the eRT and MT were smaller when stimulus velocity was faster and moving distance was short. eRT was shown to decrease with reduced moving duration in all moving velocity conditions. However, MT was shorter when moving distance was short in moving speed of 3.0m/s and 4.5m/s. Timing error was greater when stimulus velocity was faster and moving distance was shorter, but experts were more accurate than novices. In addition, temporal accuracy decreased with increasing moving velocity in all moving distance. These findings indicated that moving velocity and moving distance served as the major determinants of timing accuracy on short pass.

The purpose of this study was to investigate the constructs of sport demotivation. To explore the constructs, four open-ended questions were presented to 144 collegiate athletes who are belong to 8 different sport teams. With the inductive and qualitative content analysis, 7 factors were emerged and named for the sport training demotivation; reduced physical condition, excessive training, psychological readiness deficiency, training program dissatisfaction, sport setting, interpersonal problems between teammates, and less skilled performance. And for the sport competition demotivation, 6 factors were classified; negative psychological condition, reduced physical condition, competition leading position, loss of control, less skilled performance, and interpersonal problems between teammates.

자극의 속도와 이동거리가 농구 패스의 계획과 실행 및 정확성에 미치는 영향

홍승분 ( Seung Bun Hong ) 한국스포츠심리학회 2009 한국스포츠심리학회지 Vol.20 No.4

이 연구의 목적은 자극의 이동속도와 이동거리가 패서의 기술수준별로 정확한 패스 동작을 수행하는데 필요한 동작계획시간과 동작실행시간, 그리고 패스의 타이밍 정확성에 어떠한 영향을 미치는지 알아보는 데 있다. 이를 위해 초보자 15명과 숙련자 15명의 대상에게 불빛 자극의 이동속도(1.5m/s, 3.0m/s, 4.5m/s)와 이동거리(2m, 4m)가 다른 과제 상황에서 불빛 자극이 목표지점에 도달하는 시점과 일치되게 패스를 수행하도록 하였다. 실험과제는 각 조건 당 5회씩 총 30회가 무선으로 제시되었으며, 매 시행마다 추정반응시간, 동작시간, 그리고 타이밍의 정확성을 측정하였다. 그 결과, 초보자와 숙련자 모두 자극의 이동속도가 동일한 조건에서는 이동거리가 길어질수록 추정반응시간과 동작시간도 길어지는 것으로 나타났다. 단, 숙련자의 경우, 자극이 느린 속도로 이동할 때에는 자극이동거리 간 동작시간의 차이는 나타나지 않았다. 절대오차는 느린 속도로 이동한 경우를 제외하고는 중간조건과 빠른 조건 모두 자극의 이동거리가 길어질수록 타이밍 정확성은 높아졌다. 또한 초보자와 숙련자 모두 자극이동거리가 길수록 패스의 타이밍 정확성은 높은 것으로 나타났다. The study was to investigate the effects of ball receiver`s moving speed and moving time(in distance) on passer`s movement planning(measured as estimated RT), movement time, and ultimately on temporal accuracy(timing error) of passed ball. Fifteen novice players along with fifteen expert players were required to make a total of 30 passes in coincidence with an experimentally manipulated moving light signal in randomly presented six different conditions, i.e., in three differing light speed(1.5m/s; 3.0m/s; 4.5m/s) and in two differing moving time(operationally manipulated in moving distance: 2m or 4m). Analyses of data disclosed that moving stimulus velocity and stimulus duration had differential effects on eRT(estimated reaction time), MT(movement time), and ultimately on timing error as a function of skill level, respectively. Analyses of eRT and MT data using three-way ANOVA with repeated measures revealed eRT and MT were smaller when there was less time available as resulted from increasing stimulus velocity with reduced moving duration. Timing error was greater when stimulus velocity was faster and duration was shorter, but expert were more accurate than novices in the all stimulus conditions. These results were interpreted to mean that moving velocity and moving duration served as the major determinants of temporal accuracy of ball passing.

The purpose of this study was to investigate the effects of receiver’s moving speed and passer’s skill level on arm control mechanism of passing in basketball using phase plane plots(angle-angular velocity plots) for the three joints of right arm. Four novice players along with four expert players were required to make a total of 15 passes in coincidence with an experimentally manipulated moving light signal in randomly presented three different light speed(1.5㎧; 3.0㎧; 4.5㎧). Qualitative analyses of the phase plane plots of shoulder, elbow, and wrist joint disclosed that 1) stimulus velocity had no differential effects on phase plane plots meaning joint control mode in both expert and novice, and 2) passer’s skill level had differential effects on phase plane plots of shoulder and elbow joint. Expert accepted the position-dependent control mode as in springs or pendular in shoulder and elbow joint during passing. But novice operated elbow joint in smooth accelerations and decelerations, in which reversals occurred only at movement extremes. 3) There was no differential effects in wrist joint as a function of passer’s skill level. We suggested in based on these results that research paradigm for temporal accuracy should shift from information-processing approach measuring temporal-spatial timing errors, movement time(MT), and reaction time(RT) to dynamic system approach focusing on coordination patterns, control variables, and control parameters in the future.

The aim of the current study was to examine influences of collegiate judo student-athletes’degree of athletic identity and coping resources on expected career transition difficulties. Data were collected from collegiate judo student-athletes(MA=89) who were actively involved in judo. We used three different questionnaires, including Athletic Identity Measurement Scale[AIMS], Transition Coping Questionnaire[TCQ] and the Korean Athlete Lifestyle Assessment Needs in Career and Education Scale[KALANCE]. To identify influences of student-athletes’athletic identity and coping resource on expected career transition difficulties, data were analysed by a Pearson’s correlation and multiple regressions. Findings revealed that the degree of athletic identity was different depending on their academic years(2nd and 3rd years were higher than 1st and 4th years student-athletes). In addition, the results indicated that athletes’ coping resources, such as use of social support, coping strategies, and transition situation were negatively related to career transition difficulties and the degree of athletic identity had also negatively associated with the career transition difficulties. The findings also showed that international level student-athletes had better coping resources than domestic level student-athletes. The current results provided ideas related ways to assist student-athletes’ career transition out of sport.

The purpose of this study was to see if there was a relationship between perfectionism and sport demotivation which includes sport training demotivation and sport competition demotivation, and to find out which factors of perfectionism minght be the predictors of sport demotivation. To confirm these two hypotheses, a total of 204 martial art athletes completed multidimensional perfectionism scale and sport demotivation scale. With the data gained from 204 athletes, correlation analysis was used to examine the relationship between perfectionism and sport demotivation. Additionally the perfectionism subscales were entered into the regression to figure out which subscales are the predictors of sport demotivation. First, it was found that there was a certain relationship between perfectionism and sport demotivation. Second, it was found that other-oriented perfectionism and socially prescribed perfectionism had positive effects on negative training atmosphere and reduced self-confidence of sport training demotivation, while self-oriented perfectionism had no significant effect on sport training demotivaion. In addition, self-oriented perfectionism had a negative effect on reduced performance ability and loss of goal of sport competition demotivation, while socially prescribed perfectionism had positive effects on both of them. Meanwhile, other-oriented perfectionism had a positive effect on loss of goal but a negative effect on reduced performance ability of sport competition demotivation.

The purpose of the present study was to examine relationships between athletic identity, resources related to transitions, and the quality of career transition adjustment of Korean Olympic athletes. Data were collected by active Korean elite athletes(N=106; MA=25.74; 45 males &; 61 females) who participated 2012 London Olympic Games through three different questionnaires(i.e., Athletic Identity Measurement Scale[AIMS], Transition Coping Questionnaire[TCQ] and the Korean Athlete Lifestyle Assessment Needs in Career and Education[KALANCE] Scale. A Pearson correlation and multiple regressions were used to analyze the data to identify relationships between the degrees of their athletic identity, resources related to transitions, and expected difficulties of career transition adjustment. The results indicated that participants degree of athletic identity had a positive relationship with the quality of athletes’career transitions. Regarding to athletes’resources, the findings revealed that athletes’situation of their transitions, social support, and coping strategies had positive influence on the quality of expected their career transition adjustment. However, self factor did not show any association with the quality of their career transition adjustment. The current study was the first study examining variables related to expect active Korean Olympic athletes’transition difficulties and provided future research directions, such as a need of examining the ways to develop athletes’readiness for retirement while actively competing.
