RESUMEN

The purpose of the current study was to implement and evaluate an athlete leadership development program in youth boys ice hockey. The sample consisted of 14 male U17 hockey players (M = 16.46, SD = 0.78) from one team playing in a competitive hockey league. The players participated in six leadership intervention workshops over the course of the season, and completed inventories measuring athlete leadership behaviours, cohesion, and collective efficacy pre-and post-intervention. In addition, a focus group was conducted to assess the impact of the athlete leadership development program at the end of the season. Bayesian t tests showed that the leadership program generally helped to maintain levels of athlete leadership behaviours, cohesion, and collective efficacy pre-and post-intervention. The results of the focus group following the intervention revealed the players believed the leadership development program helped buffer against the negative effects of their on-ice performances.

RESUMEN

PURPOSE: Much of what we know about pedometer interventions and imagery interventions with children is grounded in quantitative data. The general purpose of the present study was to qualitatively explore the experiences of children who had participated in a 4-week imagery intervention designed to increase active play. Specifically, the current study investigated children's experiences with (a) wearing pedometers and (b) listening to audio recordings (imagery scripts and short stories) via an automated telephone system. METHOD: Two focus-group interviews were conducted with a subsample of children (aged 9-10 years) who had completed the imagery intervention: 1 interview with children from the imagery group (n = 7) and 1 with children from the control group (n = 5). RESULTS: Findings indicated that children enjoyed wearing pedometers. At the same time, children reported some complaints about wearing these devices (e.g., they are uncomfortable). Children also described that the automated telephone system was fun to use, despite the fact that it was difficult to remember to call the system 3 times each week. Finally, children in the imagery group noted that the imagery scripts were easy to imagine and motivated them to engage in active play, while children in the control group found the short stories interesting. CONCLUSION: The results of the current study can help researchers and practitioners develop and implement effective pedometer and imagery interventions with children.

RESUMEN

The purpose of the current study was to develop an instrument, the Children's Active Play Imagery Questionnaire (CAPIQ), to assess imagery use during children's (7-14 years) active play. Phase 1 involved an assessment of content validity using experts (N = 7), while Phase 2 assessed the factorial validity of the CAPIQ using a sample of children (N = 302). Phase 3 contributed to the factorial validity of the CAPIQ by utilising confirmatory factor analysis among an independent sample of children (N = 252). The final version of the CAPIQ consists of 11 items across three factors: fun, social and capability. Further use of the CAPIQ will aid in identifying types of imagery used among children (7-14 years) in their active play, which may contribute to physical activity interventions.

RESUMEN

We assessed the factor structure of a revised version of the Exercise Imagery Inventory (ELI; Giacobbi, Hausenblas, & Penfield, 2005), second-order interrelationships for cognitive and motivational forms of mental imagery, and associations with exercise behavior and barriers self-efficacy. A convenience sample of 358 (M age = 20.55 years, SD = 3.88) college students completed the EII-revised (EII-R), a measure of barriers self-efficacy and the Leisure-Time Exercise Questionnaire. The EII-R demonstrated reliability and factorial validity with good model fit statistics. We observed second-order relationships among scale scores and discriminant validity evidence that distinguished cognitive (e.g., exercise technique, exercise routines) and motivational (e.g., appearance/health, exercise self-efficacy, exercise feelings) factors. The second-order imagery factors were significantly and moderately associated with barriers self-efficacy and exercise behavior.

RESUMEN

Muscle dysmorphia is a form of body dysmorphic disorder in which individuals have a pathological preoccupation with their muscularity and, more specifically, an extreme fear that their bodies are too small. Relatively few empirical studies have been completed on muscle dysmorphia, and even fewer studies on the relationship between the drive for muscularity and muscle dysmorphia in men and women. The purpose of this research was to examine the relationship between the drive for muscularity and muscle dysmorphia in male (n = 55) and female (n = 59) recreational weight trainers. Results revealed that the behavior and diet subscales of the drive for muscularity significantly predicted muscle dysmorphia in males and females accounting for 69% and 46% of the total variance, respectively. Although the overall scores of muscle dysmorphia do not indicate clinical levels, these findings suggest that behaviors such as arranging one's schedule around his/her training regimen and dieting in order to gain muscle predict characteristics of muscle dysmorphia in men and women.

RESUMEN

The present study investigated 345 athletes' (male = 152, female = 193) use of observational learning and imagery for practice and at competition and how this related to sport confidence. The Functions of Observational Learning Questionnaire (Cumming et al., 2005), the Sport Imagery Questionnaire (Hall et al., 1998), and the Trait Sport Confidence Inventory (Vealey, 1986) were contextualized by asking participants to rate each item twice, once for practice and once for competition. The athletes reported using each of the different functions of observational learning and imagery in these situations, but the pattern of use differed. Whereas nearly all of the imagery functions were more frequently used at competition, the majority of observational learning functions were used more for practice. Cognitive specific and motivational general-mastery imagery were significant predictors of sport confidence in practice and competition, whereas the skill function of observational learning significantly predicted practice confidence only.

RESUMEN

Confidence has been one of the most consistent factors in distinguishing the successful from the unsuccessful athletes (Gould, Weiss, & Weinberg, 1981) and Bandura (1997) proposed that imagery is one way to enhance confidence. Therefore, the purpose of the present study was to examine the relationship between imagery use and confidence in soccer (football) players. The participants included 122 male and female soccer athletes ages 11-14 years participating in both house/ recreation (n = 72) and travel/competitive (n = 50) levels. Athletes completed three questionnaires; one measuring the frequency of imagery use, one assessing generalised self-confidence, and one assessing self-efficacy in soccer. A series of regression analyses found that Motivational General-Mastery (MG-M) imagery was a signifant predictor of self-confidence and self-efficacy in both recreational and competitive youth soccer players. More specifically, MG-M imagery accounted for between 40 and 57% of the variance for both self-confidence and self-efficacy with two other functions (MG-A and MS) contributing marginally in the self-confidence regression for recreational athletes. These findings suggest that if a youth athlete, regardless of competitive level, wants to increase his/her self-confidence or self-efficacy through the use of imagery, the MG-M function should be emphasised.

RESUMEN

To investigate whether coaches encourage their athletes to use imagery, two studies were undertaken. In the first, 317 athletes completed the Coaches' Encouragement of Athletes' Imagery Use Questionnaire. In the second, 215 coaches completed a slightly modified version of this questionnaire. It was found that coaches and athletes generally agreed on the relative frequency with which coaches encourage athletes to use imagery across the 4 Ws (i.e., where, when, why, and what). Coaches promoted imagery use more in conjunction with competition than training and injury rehabilitation, and higher-level coaches encouraged imagery use far more than their recreational counterparts. In addition, the level of athlete being coached had a major impact on how much or little coaches encouraged their athletes to use imagery. Coaches encouraged higher level athletes (i.e., international, national, varsity) to use imagery more than club and recreational athletes.

RESUMEN

Investigations in a variety of chronologically grouped team sports have reported that elite young athletes were more likely born in the early months of the selection year, a phenomenon known as the relative age effect. The present study investigated the birth dates and developmental paths of 238 (15 to 20 years old) Major Junior 'A' hockey players from the Ontario Hockey League to determine if a relative age effect still exists in elite junior hockey and if the path to elite sport was accelerated (i.e., fast tracked). The results identified a relative age effect in elite hockey although it is only apparent among individuals who fast track.

RESUMEN

The purpose of this study was to investigate young athletes' imagery use from a developmental perspective. The participants were 110 male and female athletes competing in both team and individual sports. They represented four different age cohorts (i.e., 7-8, 9-10, 11-12, and 13-14 years). Sixteen focus groups, two for each age category and gender, were used as the method of data collection. The findings indicated "where," "when, " and "why" young athletes use imagery and how imagery use changes as children move from early childhood through to early adolescence. Overall, results revealed that all age cohorts reported using imagery in both training and competition and for both cognitive and motivational purposes. The present research also found support for studying imagery use by young athletes from a developmental perspective.

RESUMEN

Recent exercise imagery findings suggest that past research in this field has been shortsighted and has severely curtailed progress in this important area. The authors provide a conceptual framework that focuses on how imagery may impact exercise behavior. This model expands our current knowledge of exercise imagery to suggest how it may function as an effective intervention to increase exercise behavior.
