Few studies have explored the relation between withdrawn behavior (WB) and exercise and screen time. The current study used exploratory factor analysis to examine the factor structure of leisure-time exercise behavior (LTEB) and screentime sedentary behavior (STSB) in a clinical sample of youth. Structural equation modeling was employed to investigate the relations between WB and LTEB and STSB, conditional on gender. WB was assessed using the Child Behavior Checklist, and LTEB and STSB were measured using the Vermont Health Behavior Questionnaire. LTEB and STSB emerged as two separate factors. Gender moderated the structure of STSB only. For boys and girls, WB was inversely related to LTEB but not significantly related to STSB. LTEB and STSB are best represented as distinct, uncorrelated constructs. In addition, withdrawn youth may be at risk for poor health outcomes due to lower rates of LTEB. Mental health clinicians, sports psychologists, and related providers may be uniquely qualified to enhance motivation for sports participation in withdrawn youth.

The main purpose of this study was to examine the links of coach-athlete relationship (CAR) and perceived coach-created motivational climate to persistence in youth sport. A total of 1692 persistent and 543 withdrawn football, ice hockey, and basketball players, aged 15–16 years, completed the Coach-Athlete Relationship Questionnaire and the Perceived Motivational Climate Sport Questionnaire. Results indicated that persistent players reported higher scores in CAR and task-climate than withdrawn players. Persistent players also represented higher competition level, higher amount of training, and more years of involvement in sport than withdrawn players. Cluster analysis identified three profiles: 1) High CAR, high task climate, and moderate ego climate, 2) Moderate CAR, moderate task climate, and moderate ego climate, and 3) Low CAR, low task climate, and high ego climate. Differences between profiles were found in terms of relative proportion of continuing players, competition level, and amount of training. In all, Profile 1 appeared to be the most beneficial from the perspective of sport persistence. The present findings lend support for the view that coach-athlete relationship and motivational climate together can have implications for young athletes’ maintenance in organized sports.

This article examines patterns of adjustment among urban middle-school children as a function of involvement in organized team sports. Four hundred twenty-three seventh-grade students (216 boys and 207 girls) reported on their involvement in sport, self-esteem, delinquent activity, and drug use during the year preceding the survey. Physical Education teachers rated social competence, shyness/withdrawal, and disinhibition/aggression. Compared with noninvolved children, sport-involved youth reported higher self-esteem and were rated by teachers as more socially competent and less shy and withdrawn. Sport-involved youth, including those in contact sports, were not rated as more aggressive than noninvolved children. And though sport-involved youth reported a slightly broader range of delinquent activities than noninvolved youth, sport-involved boys were actually less likely than noninvolved boys to have experimented with marijuana.

The present study involved three in-depth interviews with 10 informants who had voluntarily withdrawn from hockey, horse racing, football, and racquet-ball. The personal histories of the informants were examined for diversity and commonality of experience. A synthesized description of career change experience was written as a general story, identifying a sequence of experiential units that reflect the shifts in focus within the common experience. The general story indicated that withdrawal from sport was not simply an event but a process that began soon after the athletes became engaged in their career. This study supports and extends a model proposed by Schlossberg (1984) which attempts to account for diversity in the experience of transitions. The model is considered helpful in developing an understanding of the process of a transitional experience such as retirement from sport, considering the context in which the experience takes place, the meaning it has for the individual, and how it changes over time.

This study reports results from the first phase of a large-scale research project designed to examine burnout in competitive junior tennis players. Thirty junior tennis burnout and 32 comparison players, identified by U.S. Tennis Association personnel, voluntarily completed a battery of psychological assessments. A series of discriminant function analyses and univariate t-tests revealed that burned out, as contrasted to comparison players, had significantly: (a) higher burnout scores; (b) less input into training; (c) were more likely to have played high school tennis; (d) more likely played up in age division; (e) practiced fewer days; (f) were lower in external motivation; (g) were higher in amotivation; (h) reported being more withdrawn; (i) differed on a variety of perfectionism subscales; (j) were less likely to use planning coping strategies; and (k) were lower on positive interpretation and growth coping. It was concluded that in addition to a variety of personal and situational predictors of burnout, perfectionism plays a particularly important role.

The individualized nature of instructional programs for the mentally handicapped often makes group designs inappropriate in adapted physical activity research. Single-subject time-series designs are suitable for use in investigating the acquisition, maintenance, and generalization of motor skills when the research involves small numbers of subjects. These designs require the collection of data before, and during or after treatment. Three single-subject time-series designs are described and illustrated with data from studies in the PREP Play Program, an instructional program for young mentally handicapped children at the University of Alberta. The simple time-series design has severe limitations for use as a research tool, but is appropriate for use by teachers or practitioners who are monitoring previously tested treatments in physical activity programs. The repeated time-series or reversal design can be used to investigate the maintenance or generalization of effects after treatments are withdrawn. The multiplebaseline design is recommended for researchers or practitioners who wish to assess the effects of instructional programs on different subjects or different dependent variables.

The purpose of this study was to assess the effect of interferential current (IFC) on perceived pain and serum Cortisol levels in subjects with delayed onset muscle soreness (DOMS). DOMS was induced in 10 subjects through repeated eccentric contractions of the elbow flexors. Forty-eight hours later subjects were evaluated. Starting at t = 0:00, blood samples were withdrawn from a superficial vein every 5 min for 65 min. At t = 0:05, subjects received IFC of 10 bps or IFC of 100 bps. Perceived pain levels were evaluated prior to catheter insertion and at t = 0:35, 0:50, and 0:65. Two mixed-model analyses of variance revealed a significant decrease in perceived pain scores across time for both treatment groups but no significant difference in serum Cortisol for the two groups. It was concluded that IFC of high and low beat frequency is effective in controlling the pain of DOMS but does not elicit a generalized stress response as indexed by increasing serum Cortisol levels.
