Bullying Victimization and Perpetration Among Adolescent Sport Teammates

Blair Evans, Ashley Adler, Dany MacDonald, and Jean Côté

Purpose:

Bullying is a specific pattern of repeated victimization explored with great frequency in school-based literature, but receiving little attention within sport. The current study explored the prevalence of bullying in sport, and examined whether bullying experiences were associated with perceptions about relationships with peers and coaches.

Method:

Adolescent sport team members (n = 359, 64% female) with an average age of 14.47 years (SD = 1.34) completed a pen-and-paper or online questionnaire assessing how frequently they perpetrated or were victimized by bullying during school and sport generally, as well as recent experiences with 16 bullying behaviors on their sport team. Participants also reported on relationships with their coach and teammates.

Results:

Bullying was less prevalent in sport compared with school, and occurred at a relatively low frequency overall. However, by identifying participants who reported experiencing one or more act of bullying on their team recently, results revealed that those victimized through bullying reported weaker connections with peers, whereas those perpetrating bullying only reported weaker coach relationships.

Conclusion:

With the underlying message that bullying may occur in adolescent sport through negative teammate interactions, sport researchers should build upon these findings to develop approaches to mitigate peer victimization in sport.

Activity-Related Support From Parents, Peers, and Siblings and Adolescents’ Physical Activity: Are There Gender Differences?

Kirsten Krahnstoever Davison

Background.

A comprehensive measure of activity-related support was developed and used to examine gender differences in activity support and links between support and physical activity in a sample of adolescents.

Methods.

Participants included 202 middle school girls and boys. Participants completed the Activity Support Scale and three self-report measures of physical activity.

Results.

Seven sources of support were identified including maternal and paternal logistic support, maternal and paternal modelling, general familial support, sibling support, and peer support; all scales were internally consistent. No gender differences in activity-related support were identified. Adolescents who were more active reported higher levels of activity support from all sources except maternal and paternal modelling of physical activity.

Conclusion.

Results from this study highlight the importance of activity-related support from family and friends as a potential method to promote and sustain physical activity among adolescents.

Low Cardiorespiratory Fitness Is Partially Linked to Ventilatory Factors in Obese Adolescents

Monique Mendelson, Anne-Sophie Michallet, Julia Tonini, Anne Favre-Juvin, Michel Guinot, Bernard Wuyam, and Patrice Flore

Aim:

To examine the role of ventilatory constraint on cardiorespiratory fitness in obese adolescents.

Methods:

Thirty obese adolescents performed a maximal incremental cycling exercise and were divided into 2 groups based on maximal oxygen uptake (VO2peak): those presenting low (L; n = 15; VO2peak: 72.9 ± 8.6% predicted) or normal (N; n = 15; VO2peak: 113.6 ± 19.2% predicted) cardiorespiratory fitness. Both were compared with a group of healthy controls (C; n = 20; VO2peak: 103.1 ± 11.2% predicted). Ventilatory responses were explored using the flow volume loop method.

Results:

Cardiorespiratory fitness (VO2peak, in % predicted) was lower in L compared with C and N and was moderately associated with the percent predicted forced vital capacity (FVC) (r = .52; p < .05) in L. At peak exercise, end inspiratory point was lower in L compared with N and C (77.4 ± 8.1, 86.4 ± 7.7, and 89.9 ± 7.6% FVC in L, N, and C, respectively; p < .05), suggesting an increased risk of ventilatory constraint in L, although at peak exercise this difference could be attributed to the lower maximal ventilation in L.

Conclusion:

Forced vital capacity and ventilatory strategy to incremental exercise slightly differed between N and L. These results suggest a modest participation of ventilatory factors to exercise intolerance.

Early Adolescent Participation in Physical Activity: Correlates With Individual and Family Characteristics

Peter Mulhall, Janet Reis, and Shahana Begum

Background:

Early adolescence is developmental period when youth begin to shift exercise and physical activity patterns toward increased sedentary living. The major causes and contributing factors to this change are poorly understood. This study examines the relationship between sociodemographic factors, behavioral and family factors that influence physical activity patterns of middle grades students.

Methods:

The 1578 youth ranged in age from 12 (22%) to 13 (78%) and were divided between white (65%), African American (19%), and Hispanic (16%) subpopulations, with 37% overall qualifying for reduced-price or free school lunches. The assumptions for Analysis of Covariance versus Analysis of Variance (ANOVA) were examined, with the final results reported separately for attitudes toward exercise as predictors and sociodemographic variables and measures of family functioning as predictors.

Results:

Positive attitudes were more strongly associated than were negative attitudes with exercise. Of the categorical predictors, student gender and family involvement with fitness had the most statistically significant associations with self reported exercise (6 for gender and 5 for family involvement with fitness).

Conclusions:

The results of this analysis of a diverse and large sample of young adolescents are placed in the context of family leisure and work time in our “hurried” culture.

Coping and Coping Effectiveness in Relation to a Competitive Sport Event: Pubertal Status, Chronological Age, and Gender among Adolescent Athletes

Adam Nicholls, Remco Polman, David Morley, and Natalie J. Taylor

An aim of this paper was to discover whether athletes of different pubertal status, chronological age, and gender reported distinct coping strategies in response to stress during a competitive event in their sport. A secondary aim was to examine pubertal status group, chronological age, and gender differences in coping effectiveness. Participants were adolescent athletes (n = 527), classified as beginning-pubertal (n = 59), midpubertal (n = 189), advanced-pubertal (n = 237), and postpubertal (n = 22). Findings revealed that there were small, but significant differences in how athletes of different pubertal status and chronological age coped. There were also significant differences between how athletes of different pubertal status perceived the effectiveness of their coping strategies. Interestingly, our results suggested that the relationship between pubertal status and coping and coping effectiveness is different from the relationship between chronological age and coping and coping effectiveness.

Exploration of the Mechanisms of Change in Constructs From Self-Determination Theory and Quality of Life During a Multidisciplinary Family-Based Intervention for Overweight Adolescents

Ashley A. Fenner, Erin K. Howie, Leon M. Straker, and Martin S. Hagger

The current study explored whether a multidisciplinary family-based intervention underpinned by self-determination theory could enhance perceptions of parent need support, autonomous motivation, and quality of life in overweight and obese adolescents. Using a staggered-entry waitlist-period control design, adolescents (n = 56) were assessed at baseline and preintervention (within-participant control), immediately following intervention, and at 3, 6, and 12 month follow-ups. Parents were trained in need-supportive behaviors within the broader context of an 8-week multidisciplinary intervention attended jointly with adolescents. Following intervention, significant improvements were demonstrated in adolescent perceptions of parent need support, autonomous motivation, and quality of life, and changes were maintained at the 1-year follow-up. Mediation analyses revealed changes in perceptions of parent need support predicted changes in quality of life indirectly via changes in autonomous motivation. Findings suggest overweight and obese adolescents are likely to benefit from multidisciplinary family-based interventions that aim to train parents in need-supportive behaviors.

Short-Term Resistance Training Attenuates Cardiac Autonomic Dysfunction in Obese Adolescents

Paulo Farinatti, Silvio Rodrigues Marques Neto, Ingrid Dias, Felipe A. Cunha, Eliete Bouskela, and Luiz G. Kraemer-Aguiar

Purpose:

Cardiac autonomic dysfunction (CADysf) in children is often associated to obesity and may be attenuated by physical activity. In this study, we investigated the effects of resistance training (RT) upon CADysf assessed by heart rate variability (HRV) in obese adolescents.

Method:

Volunteers were assigned into groups according to standard deviation scores for body mass index (z-BMI) and percentile for age and sex: obese (OB; z-BMI from 2 to 3 and ≥ 95th percentile, n = 24) and normal weight controls (CG; z-BMI from -2–1 and < 85th percentile, n = 20). OB performed isolated RT during 12 weeks [3 sets of 6–10reps with 70–85% 10RM]. Waist circumference, systolic/diastolic blood pressures (SBP/DBP), lipids, and HRV were assessed at baseline. Only OB underwent postintervention assessments.

Results:

At baseline, SBP (122.4 ± 9.1 vs. 109.7 ± 11.5 mmHg, p < .001) and DBP (76.1 ± 7.1 vs. 65.3 ± 5.9 mmHg, p < .001) were higher, while parasympathetic HRV indexes were lower (p < .05) in OB compared with CG. After RT, waist circumference (3%, p < .001) and SBP (10%, p < .001) reduced in OB. Parasympathetic indexes of HRV increased in OB (SDNN: 25%, p = .03; rMSSD: 48%, p = .0006; pNN50: 67%, p = .001; total power: 54%, p = .01; HF: 101%, p = .001) and baseline differences between groups for sympathetic and parasympathetic activities were no longer observed after RT.

Conclusion:

RT attenuated CAdyfs and BP in obese adolescents, by increasing parasympathetic activity and decreasing sympatho-vagal balance.
