This article reviews the role of augmented biofeedback as a treatment aid for selected neuromuscular problems in children and adolescents with cerebral palsy. Neuromuscular dysfunction often prevents those inflicted with cerebral palsy from performing even simple tasks of daily activity. Research has evaluated the role of augmented biofeedback in reducing this neuromuscular dysfunction. Augmented feedback, on the whole, has been successful in improving head and neck posture, reducing hypertonicity, and improving weight-bearing during gait, hand-eye coordination, sitting posture, and drooling. However, most studies have shown that the carry-over without feedback was limited. Moreover, the generalization to real-life situations often was not demonstrated. The sample size in most studies was very small. Future research should address the adequate number of training sessions needed to produce an improvement and consider the mode and type of feedback appropriate for a given subject. Augmented biofeedback appears to have important implications in the treatment of those with cerebral palsy.

Investigations of visually guided target-directed movement frequently adopt measures of within-participant spatial variability to infer the contribution of planning and control. The present study aims to verify this current trend by exploring the distribution of displacements at kinematic landmarks with a view to understand the potential sources of variability. Separate sets of participants aiming under full visual feedback conditions revealed a comparatively normal distribution for the displacements at peak velocity and movement end. However, there was demonstrable positive skew in the displacement at peak acceleration and a significant negative skew at peak deceleration. The ranges of the distributions as defined by either ±1SD or ±34.13th percentile (equivalent to an estimated 68.26% of responses) also revealed differences at peak deceleration. These findings indicate that spatial variability in the acceleration domain features highly informative systematic, as well as merely inherent, sources of variability. Implications for the further quantification of trial-by-trial behavior are discussed.

Baby Boomers might not consider themselves as growing old but are starting to reach the last quarter of average life spans. This article asks how Boomers prepare for their fourth quarters through physical activity. Three years (1999–2001) of National Health Interview Survey data yielded 96,501 adult respondents. Dependent variables were moderate, vigorous, and strengthening activity. Old boomers (1946–1955) and young boomers (1956–1965) were compared to respondents born before 1926, after 1975, and 10-year cohorts between. SUDAAN multiple logistic regression adjusted for complex sampling structure and multiply imputed income. Age-adjusted, older cohorts showed greater likelihood of activity than younger cohorts, offsetting moderate-activity declines with age until sharp decreases at advanced age: a plateau across Boomer and younger-aged cohorts. Interventions should promote activity at intensities and frequencies to which Boomers are most receptive.

This study examined the effectiveness of a logbook and paperclip technique on awareness of the use and content of negative self-talk as well as the motivation to change negative self-talk. Participants (n = 73) completed a questionnaire measuring these variables, and were assigned to either a control, paperclip or logbook group. Participants performed three typical training sessions over a three-week period. The logbook group completed a self-talk logbook after each session whereas the paperclip group carried out a paperclip exercise during each session. Upon completion of the training sessions, the questionnaire was readministered. ANCOVAs revealed no significant differences between the groups for motivation to change and awareness of the content of negative self-talk. However, the logbook group had significantly greater awareness of their use of negative self-talk compared with the control group. A qualitative analysis of the logbook group’s use of negative self-talk provided insights into the situations that prompted negative self-talk, the content of the self-talk, and also the consequences of using negative self-talk. Collectively, the findings offer some support for the use of the logbook technique in the applied setting.

Fifteen adult male volunteers were assigned to sedentary, moderately strength-trained, and moderately endurance-trained groups (5 per group) to determine the effect of exercise training on energy expenditure (EE). Subjects were matched for age, weight, and height. Group appointments were based on activity questionnaires and American College of Sports Medicine standards. Subjects consumed a mixed diet of 40% fat, 20% protein, and 40% carbohydrate at weight maintenance intake for 3 weeks while continuing their exercise training programs. There was no significant difference between groups for 24-hr EE measured in the controlled environment of a room-sized calorimeter. Free-living EE measured with

Purpose: The purpose of this investigation was to examine the weight management (WM) behaviors of collegiate wrestlers after the implementation of the NCAA’s new weight control rules. Methods: In the fall of 1999, a survey was distributed to 47 college wrestling teams stratified by collegiate division (i.e., I, II, III) and competitive quality. Forty-three teams returned surveys for a total of 741 responses. Comparisons were made using the collegiate division, weight class, and the wrestler’s competitive winning percentage. Results: The most weight lost during the season was 5.3 kg ± 2.8 kg (mean ± SD) or 6.9% ± 4.7% of the wrestler’s weight; weekly weight lost averaged 2.9 kg ± 1.3 kg or 4.3% ± 2.3% of the wrestler’s weight; post-season, the average wrestler regained 5.5 kg ± 3.6 kg or 8.6% ± 5.4% of their weight. Coaches and fellow wrestlers were the primary influence on weight loss methods; however, 40.2% indicated that the new NCAA rules deterred extreme weight loss behaviors. The primary methods of weight loss reported were gradual dieting (79.4%) and increased exercise (75.2%). However, 54.8% fasted, 27.6% used saunas, and 26.7% used rubber/ plastic suits at least once a month. Cathartics and vomiting were seldom used to lose weight, and only 5 met three or more of the criteria for bulimia nervosa. WM behaviors were more extreme among freshmen, lighter weight classes, and Division II wrestlers. Compared to previous surveys of high school wrestlers, this cohort of wrestlers reported more extreme WM behaviors. However, compared to college wrestlers in the 1980s, weight loss behaviors were less extreme. Conclusions: The WM practices of college wrestlers appeared to have improved compared to wrestlers sampled previously. Forty percent of the wrestlers were influenced by the new NCAA rules and curbed their weight loss practices. Education is still needed, as some wrestlers are still engaging in dangerous WM methods.

This study examined the effect of motivational primes on participants (N = 171) during a cycling task. Relative to participants primed with a controlled motivational orientation, it was hypothesized that participants primed for autonomous motivation would report greater feelings of enjoyment, effort, and choice in relation to the cycling activity and report greater exercise intentions. Members of the autonomous prime group were expected to exercise for longer, at a greater percentage of their heart rate maximum, and report lower levels of perceived exertion than those in the controlled prime condition. It was found that, relative to participants in the controlled prime group, those who received the autonomous prime enjoyed the exercise more, exercised at a greater percentage of heart rate maximum, and reported a lower rating of perceived exertion. Furthermore, participants experiencing the controlled prime exercised for less time and had lower intentions to exercise than did other participants. Results highlight the importance of automatic processes in activating motivation for exercise.

The effectiveness of three learning strategies on achievement was compared in the learning and performing of a self-paced motor task. More specifically, investigated was the influence of (a) an awareness strategy (to consciously attend to the act and to what one is doing during execution); (b) a nonawareness strategy (to preplan the movement and perform the task without conscious attention to it; “to just do it”); (c) the Five-Step Approach (to systematically ready oneself, image the act, focus attention on a cue, execute without thought, and evaluate the act and the previous steps); and (d) a control condition (to use one’s own approach). Subjects (N = 72) received 250 trials to master a computer-managed ball-throwing task, and 50 more in a dual-task situation. The Five-Step Approach and nonawareness strategies led to the highest achievement, and the three strategies resulted in less radial error in comparison to the control condition.

This study examined the perspectives of sport management academicians regarding their experiences supervising international graduate students. Fifteen experts were interviewed and provided their perspectives on practices used in international student involvement—specifically, student identification, recruitment, acceptance, orientation, progress, and retention, and the inherent challenges and benefits. The primary challenges cited by the majority of participants were language and cultural differences in learning; however, all participants concurred that the benefits of supervising international students far outweighed the challenges. These benefits included, but were not limited to, bringing international and global perspectives into the learning environment, which was positive for both students and professors. Findings from this study may provide program administration with insights on key factors affecting the quality of delivery of sport management education to international students. Consequently, high-quality programs can be developed to meet the needs of students from diverse cultural and educational backgrounds.

This study extends stress research by exploring sport psychologists’ experiences of organizational stressors. Twelve accredited sport psychologists (6 academics and 6 practitioners) were interviewed regarding their experiences of organizational stress within their jobs. Content analysis involved categorizing the demands associated primarily and directly with their occupation under one of the following general dimensions: factors intrinsic to sport psychology, roles in the organization, sport relationships and interpersonal demands, career and performance development issues, and organizational structure and climate of the profession. A frequency analysis revealed that academics £AOS = 201) experienced more organizational stressors than practitioners £APOS = 168). These findings indicate that sport psychologists experience a wide variety of organizational stressors across different roles, some of which parallel those found previously in other professions. The practical implications for the management of stress for sport psychologists are discussed.
