Physical activity for health

Abstract

The purpose of this study was twofold: (a) to examine the stressors experienced by injured athletes during three phases of their recovery from sport injury, and (b) to explore the differences in the stressors experienced by team as compared to individual-sport athletes. Participants comprised previously injured high-level rugby union players (n = 5) and golfers (n = 5). Semi-structured interviews were used to explore the stressors participants experienced during three phases of injury (onset, rehabilitation and return to competitive sport). Within- and cross-case analyses showed that athletes experienced sport, medical/physical, social and financial stressors. There were a number of differences in the stressors experienced across the three phases and between team and individual-sport athletes. Findings have important implications for the design and implementation of interventions aimed at managing the potentially stressful sport injury experience and facilitating injured athletes' return to competitive sport.     

Stress in elite sport performers: a comparative study of competitive and organizational stressors

The purpose of this study was to compare the content and quantity of competitive and organizational stressors in elite athletes. Ten international performers were interviewed about sources of stress. Content analysis of the data involved categorizing the demands associated primarily and directly with competitive performance (#CS = 21) under the post hoc dimension "performance issues", and the demands associated primarily and directly with the sport organization (#OS = 72) under one of the following four post hoc dimensions: "environmental issues", "personal issues", "leadership issues" and "team issues". Frequency analysis revealed that the participants mentioned the competitive stressors (sigma = 95) less than the organizational stressors (sigma = 215). Further analysis within these categories showed that the mean number of participants citing individual competitive stressors (M = 4.52) was greater than the mean number of participants citing individual organizational stressors (M = 2.99). The findings indicate that elite athletes experience and recall more demands associated primarily and directly with the sport organization than with competitive performance. Furthermore, this population appears more likely to mention similar competitive stressors but varied organizational stressors, probably because the former are inherent and endemic to elite sport, whereas the latter are essentially extraneous and widely distributed.

The organisational stressors encountered by athletes with a disability

Organisational stressors have been found to be prevalent and problematic for sport performers, with research identifying demographic differences in the stressors encountered. Nevertheless, extant sport psychology research on the topic of stress has generally focused on able-bodied athletes; whilst that which has been conducted on performers with a disability has typically recruited relatively small samples to explore a narrow selection of organisational stressors, or examined other components of the stress process. The purpose of the present study was to explore the various organisational stressors that athletes with a disability encounter. The sample comprised 18 elite athletes with a disability (10 male, 8 female) who had a classified disability and experience of competing at a major championships in their sport (e.g., Paralympic Games, World Championships). Participants took part in a semi-structured interview which was analysed by drawing from grounded theory procedures. A total of 316 organisational stressors were identified, which were abstracted into 31 concepts and four, previously conceptualised, exploratory schemes: leadership and personnel issues, cultural and team issues, logistical and environmental issues, and performance and personal issues. This study not only provides the first illustration of the prevalence of organisational stressors for athletes with a disability, but also significantly points to salient similarities and distinct differences between the stress experiences of performers with and without a disability.

Relationships between training load, injury, and fitness in sub-elite collision sport athletes

The purpose of this study was to develop statistical models that estimate the influence of training load on training injury and physical fitness in collision sport athletes. The incidence of training injuries was studied in 183 rugby league players over two competitive seasons. Participants were assessed for height, body mass, skinfold thickness, vertical jump, 10-m, 20-m and 40-m sprint time, agility, and estimated maximal aerobic power in the off-season, pre-season, mid-season, and end-season. Training load and injury data were summarised into pre-season, early-competition, and late-competition training phases. Individual training load, fitness, and injury data were modelled using a logistic regression model with a binomial distribution and logit link function, while team training load and injury data were modelled using a linear regression model. While physical fitness improved with training, there was no association (P=0.16-0.99) between training load and changes in physical fitness during any of the training phases. However, increases in training load during the early-competition training phase decreased (P= 0.04) agility performance. A relationship (P= 0.01-0.04) was observed between the log of training load and odds of injury during each training phase, resulting in a 1.50 - 2.85 increase in the odds of injury for each arbitrary unit increase in training load. Furthermore, during the pre-season training phase there was a relationship (P= 0.01) between training load and injury incidence within the training load range of 155 and 590 arbitrary units. During the early and late-competition training phases, increases in training load of 175-620 arbitrary units and 145-410 arbitrary units, respectively, resulted in no further increase in injury incidence. These findings demonstrate that increases in training load, particularly during the pre-season training phase, increase the odds of injury in collision sport athletes. However, while increases in training load from 175 to 620 arbitrary units during the early-competition training phase result in no further increase in injury incidence, marked reductions in agility performances can occur. These findings suggest that reductions in training load during the early-competition training phase can reduce the odds of injury without compromising agility performances in collision sport athletes.     

Social support and recovery from sport injury: elite skiers share their experiences.

Research suggests that social support can be an important coping resource for athletes recovering from sport injury. Few studies have investigated this claim, however. To address this gap in the literature, 10 elite downhill skiers who had recovered from serious sport injuries were interviewed about the sources of stress associated with injury and the role of social support in recovery from sport injury. This paper presents the social supportfindings that emergedfrom this research'. Content analyses of the social support data revealed that the skiers needed various types of emotional, informational, and tangible support from the occurrence of injury through the return to full activity. Members of the treatment team, the ski team, and the skiers' home support net works provided social support throughout these phases. In general, the skiers were satisfied with the support received, indicating that it reduced distress and kept them motivated throughout recovery. The findings from this research have implications for the design of sport injury interventions.     

Stressors, coping, and coping effectiveness: gender, type of sport, and skill differences

The aim of this study was to examine stressors, coping, and coping effectiveness as a function of gender, type of sport, and skill. The sample consisted of 749 undergraduate athletes (455 males, 294 females) aged 18-38 years (mean= 19.8 years). Skill was classified as international/national, county, university, and club standard. Participants completed a stressor and coping concept map (Novak & Gowin, 1984). The results revealed gender, type of sport, and skill differences in relation to stressor frequencies, coping strategy deployment, and coping effectiveness. In contrast to previous research, females used a variety of problem-focused (e.g. planning, communication, technique-orientated coping) strategies more frequently than males. Team sport athletes reported a variety of sport-specific stressors relating to the demands of playing in a team environment. The group of national/international athletes reported using more planning, blocking, and visualization, and also reported that their coping was more effective than that of less-skilled athletes.     

Social Support and Recovery from Sport Injury: Elite Skiers Share Their Experiences

Abstract

Research suggests that social support can be an important coping resource for athletes recovering from sport injury. Few studies have investigated this claim, however: To address this gap in the literature, 10 elite downhill skiers who had recovered from serious sport injuries were interviewed about the sources of stress associated with injury and the role of social support in recovery from sport injury. This paper presents the social support findings that emerged from this research¹. Content analyses of the social support data revealed that the skiers needed various types of emotional, informational, and tangible support from the occurance of injury through the return to full activity. Members of the treatment team, the ski team, and the skiers' home support networks provided social support throughout these phases. In general, the skiers were satisfied with the support received, indicating that it reduced distress and kept them motivated throughout recovery. The findings from this research have implications for the design of sport injury interventions.     

Competition stress in sport performers: Stressors experienced in the competition environment

Abstract

We examined the performance and organizational stressors encountered by elite and non-elite athletes within the competition environment. Twelve sport performers (6 elite, 6 non-elite) were interviewed about both performance and organizational-related demands experienced when preparing for competition. The framework presented identifies five performance (i.e. preparation, injury, expectations, self-presentation, and rivalry) and five organizational (i.e. factors intrinsic to the sport, roles in the sport organization, sport relationships and interpersonal demands, athletic career and performance development issues, and organizational structure and climate of the sport) stress sources. A similar quantity of performance (#PS) and organizational (#OS) stressors were encountered by elite performers (#PS = 127; #OS = 72) as by non-elite athletes (#PS = 123; #OS = 74), with some demands being common and others unique to each group. Although the findings suggest that, prior to competing, sport performers encounter more stressors pertinent to performance than those emanating from the organization, these observations highlight that all the demands faced by athletes should be considered when preparing and implementing interventions to manage competition stress.     

Young,talented and injured: Injury perceptions,experiences and consequences in adolescent elite athletes

Even though injury is common in elite sports, there is still a lack of knowledge of young athletes’ injury perception both during and after injury. The aim of this mixed-method study was, therefore, to explore, in-depth, data on injury consequences and adolescent elite athletes’ perceptions and experience of injury. Three hundred and forty adolescent elite athletes (age range 15–19), from 16 different sports, were bi-weekly monitored over 52 weeks using a valid questionnaire. Twenty athletes from the same cohort were interviewed in focus groups about injury experience and perceptions. The results show that the average bi-weekly prevalence of injury was 38.7% (95% CI 37.3–40.1), with 30.0% (n?=?102) of the athletes injured for more than half of all reporting times. An overarching theme from the focus groups highlighted the risk among young athletes of a loss of identity while injured. The findings support several suggestions that may improve the rehabilitation process and enhance rehabilitation outcomes: (a) provide clear pathways to the medical team, (b) recognize the identity loss, (c) involve the injured athletes with the rest of the teammates and (d) educate athletes about how to interpret pain signals. Future research should explore and evaluate the effectiveness and generalization of such interventions.     

Differences in self-regulatory skills among talented athletes: The significance of competitive level and type of sport

Abstract

Research has shown that talented athletes outscore their mainstream peers on the basis of self-regulation. Although valuable, this does not tell us more about the distinction between good athletes and the best, which is a prerequisite in talent development. Therefore, we examined the self-regulatory skills of 222 male and female talented athletes aged 12–16 years as a function of competitive sport level (junior international or junior national athletes) and type of sport (individual or team sports). Multivariate analyses of covariance in combination with a discriminant function analysis revealed that “reflection” distinguishes between athletes at the highest levels of excellence. Furthermore, athletes playing individual sports had higher scores on “planning” and “effort” than team sport athletes, highlighting the importance of differences between types of sport. In conclusion, we emphasize the importance of reflection as a self-regulatory skill. Reflection facilitates the development of sport-specific characteristics, which may vary by type of sport. This means that an advanced sense of reflection may help talented athletes to acquire desirable characteristics during their “talent” years to ultimately reach adult elite levels of competition.     

Psychological resilience in sport performers: a review of stressors and protective factors

Abstract

Psychological resilience is important in sport because athletes must utilise and optimise a range of mental qualities to withstand the pressures that they experience. In this article, we discuss psychological resilience in sport performers via a review of the stressors athletes encounter and the protective factors that help them withstand these demands. It is hoped that synthesising what is known in these areas will help researchers gain a deeper profundity of resilience in sport, and also provide a rigorous and robust foundation for the development of a sport-specific measure of resilience. With these points in mind, we divided the narrative into two main sections. In the first section, we review the different types of stressors encountered by sport performers under three main categories: competitive, organisational and personal. Based on our recent research examining psychological resilience in Olympics champions, in the second section we discuss the five main families of psychological factors (viz. positive personality, motivation, confidence, focus, perceived social support) that protect the best athletes from the potential negative effect of stressors. It is anticipated that this review will help sport psychology researchers examine the interplay between stressors and protective factors, which will, in turn, focus the analytical lens on the processes underlying psychological resilience in athletes.     

Effectiveness of psychological intervention following sport injury

With increasing attention given to the development and implementation of psychological interventions during the sport injury rehabilitation process, there is a need to document the effectiveness of these interventions. The purpose of this review was to summarize the empirical findings of the effects of psychological interventions in reducing post-injury psychological consequences and improving psychological coping during the injury rehabilitation process among competitive and recreational athletes. In February 2012, utilizing a comprehensive search strategy, we conducted electronic searches of multiple electronic databases for randomized and nonrandomized control trials that evaluated interventions targeting populations of injured competitive and recreational athletes age 17 years and older. We included interventions that directly intervene on injured athletes' psychological outcomes (e.g., psychological consequences, psychological coping and re-injury anxiety) and utilized psychological strategies including imagery, goal-setting, relaxation, and other common techniques during the post-injury rehabilitation period. Six studies, described in seven peer-reviewed published articles, met study inclusion criteria and were included in this review. Of those studies, two included randomized control trials, two used before and after study designs and two were case study designs. Two interventions utilized guided imagery and relaxation, two interventions utilized goal-setting and one each utilized microcounseling, written disclosure, and acceptance and commitment therapy. Guided imagery/relaxation was shown to be associated with improved psychological coping and reduced re-injury anxiety. Goal setting, however, was not directly associated with the reduction of negative psychological consequences. Other psychological techniques such as microcounseling skills, acceptance and commitment therapy, and written disclosure have demonstrated effectiveness in reducing negative psychological consequences, improving psychological coping, and reducing re-injury anxiety. Our findings suggest a significant need to develop and implement well-designed intervention studies that target improvement of post-injury psychological outcomes in order to assist injured athletes successfully recovery from sport injury.

Individual training load, fitness, and injury data were modelled using a logistic regression model with a binomial distribution and logit link function, while team training load and injury data were modelled using a linear regression model. While physical fitness improved with training, there was no association (P = 0.16 – 0.99) between training load and changes in physical fitness during any of the training phases. However, increases in training load during the early-competition training phase decreased (P = 0.04) agility performance.

These findings suggest that reductions in training load during the early-competition training phase can reduce the odds of injury without compromising agility performances in collision sport athletes.     

Predictors of poor sportspersonship in youth sports: personal attitudes and social influences

The present study examined personal and social correlates of poor sportspersonship among youth sport participants. Male and female athletes (n = 676) in the fifth through eighth grades from three geographic regions of the U.S. participated in the study. Young athletes involved in basketball, soccer, football, hockey, baseball/ softball, or lacrosse completed a questionnaire that tapped poor sportspersonship behaviors and attitudes, team sportspersonship norms, perceptions of the poor sportspersonship behaviors of coaches and spectators, and the sportspersonship norms of coaches and parents. Preliminary analyses revealed significant gender, grade, sport area, and location differences in self-reported unsportspersonlike behavior. The main analysis revealed that self-reported poor sport behaviors were best predicted by perceived coach and spectator behaviors, followed by team norms, sportspersonship attitudes, and the perceived norms of parents and coaches. Results are discussed in relation to the concept of moral atmosphere.

Moral issues in sport: the child's perspective

Sport offers opportunities for children to identify and resolve moral issues. Moral issues in sport have primarily been studied from the researcher's perspective, with the child's perspective relatively ignored. Thus, the purpose of this study was to explore the nature and content of the issues children experienced in sport. Interview participants consisted of 7 boys and 8 girls ranging in age from 10 to 12 years (M = 11.6 years, SD = 1.7) who had competitive youth sport experience. An inductive content analysis revealed that children identified issues surrounding three overall dimensions concerning fairness of adult's actions, negative game behaviors, and negative team behaviors. Specific examples of issues included unfair actions by coaches, disrespecting opponents, and selfish behavior in practice. The self-identified issues both confirmed and expanded upon the content found in hypothetical moral dilemmas in sport.
