Returning to competition after a serious injury: The role of self-determination

Abstract

We tested hypotheses grounded in self-determination theory regarding athletes' cognitive appraisals and emotional reactions when returning to competition following a serious injury. Professional male athletes (N = 225) competing in the Australian Football League were presented with return-to-competition scenarios that varied with respect to: (1) degree of self-determination and (2) salience of re-injury concern. Significant MANOVA main effects were observed for the degree of self-determination on both primary appraisals and emotional responses as well as for the salience of re-injury concern on emotional response. Follow-up ANOVA polynomial trend analyses provided support for the hypothesized trends for greater self-determination in the return to sport to result in more positive appraisals and affect. Findings support self-determination theory contentions and research indicating the psychological benefits of increased self-determination.     

A Test of Schmidt's Schema Theory of Discrete Motor Skill Learning

Abstract

Schmidt's (1975) schema theory was tested with subjects who had to emit a rapid aiming response while wearing prism glasses. The glasses enabled them to view the target, but not their responding limb or the outcome of the movement. The problem was to determine the effect of (a) training with variable target practice, and (b) experiencing visual displacement information of the target, prior to training, on performance in transfer to a novel target distance. A 2 × 2 (type of practice × displacement information) factorial design was used, in which four groups of 15 male college subjects performed 60 training trials with verbal knowledge of results. The groups with variable target practice had less error on initial transfer to the novel target and throughout transfer than the groups with nonvariable target practice. No evidence was found to indicate that rate of learning for a novel target distance during transfer in the absence of KR is a positive function of the variability of target practice in training. Nor was any effect found for experiencing visual displacement information on performance in transfer.     

Prediction of Athletic Participation in Middle School Males

Abstract

During the first ten days of the academic year the Physical Estimation and Attraction Scales (PEAS) and Bialer's Locus of Control Scale were administered to seventh and eighth grade middle school males. Subsequently, calls were issued for the fall sport season (flag football, cross-country). Stepwise discriminant analysis produced a function containing Attraction first and Estimation second, which accurately predicted athletic participation, canonical r = .35 p < .001. Use of smaller, previously factored collections of PEAS items improved the prediction, canonical r = .40, p < .001. Prediction of a single, more specific activity, cross-country, by means of the more specific factor scores produced a canonical coefficient of .47, p < .001. PEAS Factor 5, referring primarily to activities of running and hiking, developed the largest relationship with cross-country participation of any study variable. Control did not enter either of these two equations. No significant relationship was found between any study variable and adherence (remaining on the cross-country team for the complete season). It was concluded that PEAS variables are capable of predicting initial exercise involvement. In terms of developing optimal psychometric predictions of exercise recruitment and adherence, it is recommended that attitude statements be developed which are more specific and congruent to corresponding desired behaviors.     

Resting Electromyographic Triceps Surae Activity and Tonic Vibration Reflexes in Subjects with High and Average-Low Maximum Oxygen Uptake Capacities

This study was grounded in the belief systems and physical activity literature and investigated preservice teachers' belief systems toward curricular outcomes for physical education programs. Preservice teachers (N = 486; men = 62%, women = 38%) from 18 U.S. colleges/universities shared their beliefs about curricular outcomes. Preservice teachers completed a previously validated belief systems instrument designed to measure the relative importance of four outcome goals for programs (physical activity/fitness, self-actualization, motor skill development, and social development). Internal consistency reliability for the instrument was .98. A confirmatory factor analysis demonstrated a good fit of the current sample to the hypothesized outcomes model. Multivariate analysis of variance results revealed a significant interaction in outcome preservice teachers' priorities for year in school by region. The teachers' views also differed on the important outcome goals for physical education. Two critical “tensions” are discussed: (a) the need to examine more fully the consistency of preservice teacher/teacher belief systems, and (b) implications for teacher education and professional development programming. It is important to heed prospective teachers' voices and address their belief systems in teacher education programs.     

Resting Electromyographic Triceps Surae Activity and Tonic Vibration Reflexes in Subjects with High and Average-Low Maximum Oxygen Uptake Capacities

Abstract

This study was designed to investigate the effect of an interactive videodisc motor skill assessment training program on the development of preservice and inservice teachers' qualitative assessment proficiency on two motor skills: the overhand throw and catch. Twenty-seven preservice and 27 inservice physical education teachers were randomly assigned to one of three treatment conditions: interactive videodisc (IVD), teacher-directed (TD), or self-directed (SD). Motor skill qualitative assessment accuracy was evaluated on a pre- and post-test basis using a 50-item motor skill assessment accuracy test (10 performances rated on 5 components) for each skill. Analysis of covariance results indicated significant main effects for treatment for both skills. Post hoc tests revealed that for the over hand throw, the IVD and TD groups were superior to the SD group but not different from each other. For the catch, the IVD group was found to be superior to both the TD and SD groups. These findings are discussed in relation to the advantages of interactive videodisc in terms of efficiency and user independence and with comparable findings in other educational applications.     

Premotor and Motor Reaction Time As a Function of Response Complexity

Abstract

Two experiments were conducted to identify the response elements responsible for the complexity effect found by Henry and Rogers (1960). An attempt was made to determine if these elements were affecting the premotor time component of simple reaction time (SRT). If they were, a strong case could be made for the argument that neuromotor programming time was affected because premotor time is a more exact estimate of it than SRT. The results revealed that premotor time was unaffected by a forward change in movement direction, but increased as the number of movement parts increased from one to two and as the demand for movement accuracy increased. Thus, increasing the (1) number of parts and (2) accuracy demands were identified as elements of response complexity which increase programming time and support Henry and Rogers (1960) hypothesis that the time to initiate a response becomes longer as the programming process become more complex.     

The Use of Statistical Significance: A Commentary Related to Franks and Huck

Abstract

This paper focuses on the processes by which people become high school coaches. Occupational choice, professional socialization, and organizational socialization are examined, using qualitative data drawn from naturally occurring observations of coaches and informal discussions and in-depth interviews with them. Over 50% of the coaches had decided that they wanted to become a coach before entrance into college. The decision to become a coach was subjectively warranted by personal characteristics and experiences in sports, a devotion to sport, and a desire to work with young people. Youth sport coaching and student teaching which involved coaching constituted the only formal professional socialization that most of the coaches received. However, because almost all of the coaches participated in organized youth and/or high school athletics, they had a first-hand opportunity to observe their own coaches and acquire some informal images and impressions about the coaching occupation from them. Regardless of whether a neophyte began as an assistant or a head coach, technical aspects of the job and the occupation's culture were acquired by observing and listening to more experienced coaches. Through these experiences, collective understandings began to form, and the shared meanings about the occupational culture took shape. Reality shock for most novice coaches came in the form of understanding the importance the coaching culture assigns to long hours and hard work and to the realization that coaching does take an enormous amount of time. By the end of the first season, a symbolic transformation takes place and internalization of institutional expectations occurs as the neophyte begins to understand what coaching is all about.
