Withdrawal predictors among physical and performance characteristics of female competitive gymnasts

Future drop-outs (n = 27) and continuing (n = 41) female competitive gymnasts were compared with respect to their physical, performance and injury characteristics measured through a large battery of tests completed while they were participants in competition. Included were anthropometric variables, body composition and somatotype, strength, flexibility, endurance, power, speed and balance measurements, and previous injury information. Differences were examined through t-tests and through discriminant analyses of principal components. The results indicate that the drop-outs were as a group distinguishable from the continuing gymnasts: they were significantly older, taller and heavier which may account for the finding that they were significantly stronger, more powerful and faster, and had greater endurance. They also had a slightly more linear/ectomorphic physique with less muscularity, and performed better on most flexibility tests. Only in a gymnastic-specific flexibility variable did the continuing gymnasts out-perform the drop-outs. It was concluded that it was mainly the age factor, and presumably the social and psychological factors associated with it, that distinguished the future drop-outs from the continuing gymnasts, and that factors related to the physical make-up and performance capacities of gymnasts cannot readily predict withdrawal from the sport.     

Knowledge,nutrition and coaching pedagogy: a perspective from female Brazilian Olympic gymnasts

It is acknowledged that knowledge and knowledge bases are an important part of coach and athlete learning and that the coach – athlete relationship is crucial to knowledge created, shared and used. This said knowledge about nutrition as constructed by elite gymnasts would seem particularly important in a culture long associated with weight control practices and disordered eating. This paper provides an insight into the ways that 10 Brazilian Olympic gymnasts construct ideas pertaining to nutritional knowledge across generational periods (between 1980 and 2004) where significant organisational change in Women’s Artistic Gymnastics in Brazil occurred and included the introduction of dieticians. Drawing upon different knowledge types and paying attention to the coaching context, the life histories of 10 Olympic gymnasts were used to open a window on knowledge construction pertaining to nutrition by three generations of gymnasts. The findings draw attention to two main illustrative themes. Firstly, coaches’ personal knowledge, whilst perceived as incomplete by gymnasts, reinforced a narrative of weight loss for gymnasts regardless of generation. Secondly, the younger generations of gymnasts perceived that the introduction of dieticians into structured provision enabled them to use better structured knowledge, and with it a sense of increased autonomy and corporeal learning via the construction of tacit embodied knowledge leading to healthier practices. Reflections are given to the role of the coach, dieticians and pedagogical actions, and the continued reshaping of knowledge in elite gymnastics.     

Psychological characteristics of male gymnasts: differences between competitive levels

The purpose of this study was to examine whether any differences exist in the cognitive and behavioural strategies of gymnasts competing at different elite levels. Thirty-eight male gymnasts competing at different competitive levels in an Australian gymnastic championship completed a standardized questionnaire prior to the first day of the competition. The questionnaire focused on a number of psychological factors that may affect both training and competition. Using both t-tests and simple discriminant function analysis, it was revealed that gymnasts competing at different elite levels could be distinguished on the basis of two psychological factors, psychological recovery and self-confidence, as well as the behavioural measure, training hours. Specifically, gymnasts competing at higher elite levels versus those at lower elite levels, were better able to recover from their competitive mistakes, were more confident and trained longer per week.

Motivational variables involved in commitment of female soccer players at different competitive levels

Today more and more women are playing sport and choosing activities previously considered the exclusive domain of men, such as soccer. The main purpose of this study was to analyse the role of motivational variables (individual and team) regarding the commitment to and future expectations of playing higher levels of competition in a sample of female association soccer players (N = 117) at different levels of competition (local, regional and national leagues). Results confirm that the highest league shows high values in perception of success (ego orientation and task orientation), transactional psychological contract and future expectations. On the other hand, the local league produces high values in relational contracts. A path analysis tests a theoretical model with all the motivational variables as predictors of sporting commitment and future expectations. It shows the power of individual and team motivational variables in terms of predicting the involvement of women in soccer.     

Psychosocial correlates of bulimic symptoms among NCAA division-I female collegiate gymnasts and swimmers/divers

In this study, we tested Petrie and Greenleaf's (2007) model of bulimic symptoms in two independent samples of female collegiate swimmers/divers and gymnasts. Structural equation modeling revealed support for the model, although it also suggested additional pathways. Specifically, general societal pressures regarding weight and body were related to the internalization of those ideals and, subsequently, to increases in body dissatisfaction. Pressures from the sport environment regarding weight and appearance were associated with more body dissatisfaction and more restrictive eating. Body dissatisfaction was related to more feelings of sadness, anger, and fear among the athletes. Negative affect, body dissatisfaction, and dietary restraint were related directly to bulimic symptoms, accounting for 55-58% of its variance. These results suggest that general sociocultural pressures are influential, but weight and appearance pressures in the sport environment may be even more pervasive and negative for female athletes.     

Sport-specific musculoskeletal growth and postural control in female artistic gymnasts: a 12 month cohort study

Abstract

Female gymnasts have been evidenced to experience sport-specific growth, of which broad shoulders and narrow hips are common characteristics. In addition to being a central component of handstand performance, postural control mechanisms, including whole-body and lumbo-pelvic stability, have been identified as risk factors for overuse spinal pathology. The study aimed to develop a fundamental understanding of musculoskeletal growth and postural control responses of female artistic gymnasts in order to extend longitudinal insights into overuse spinal pathology risk. Whole-body anthropometric measures were collected for 12 competitive female gymnasts (age at recruitment: nine to 15 years) at three time points across a 12 month period. Musculoskeletal growth was partially defined as the rate of bicristal-to-biacromial breadth ratio development, and informed shoulder- and pelvis-dominant growth sub-groups. Kinematic and kinetic indicators of postural control were determined for a total of 700 handstand trials. The shoulder-dominant (gymnastics-specific) growth group was found to have significantly greater biomechanical risk for general stability (p < 0.001) than the pelvis-dominant group. Significantly greater lumbo-pelvic risk was demonstrated for the pelvis-dominant group (p < 0.001). Extended idiosyncratic examination of proportional sport-specific growth measures alongside multi-faceted risk monitoring was advocated for the effective development of future overuse pathology prevention protocols.     

Sport in Latin America from past to present: a European perspective

This chapter examines sport in Latin America in its social, cultural, and political contexts. An analysis of the development of sport in Latin America suggests that there have been a number of distinct phases influenced by the cultures of the Spanish, British and French. More recently, the games and pastimes of the United States have made a significant impact. It is suggested that the further development of sport in Latin America is hindered by a number of significant problems. It concludes that the problems faced by some countries are immense and that governments and international organizations in the developed world should offer help where appropriate.     

Gymnastics and child abuse: an analysis of former international Portuguese female artistic gymnasts

The growing competitiveness of modern sport means that children, from very early ages, are increasingly submitted to intensive training programmes. These programmes are problematic for young athletes not only because their developing bodies are particularly susceptible to different kinds of injuries, but because athletes are also particularly vulnerable to experiences of different kinds of abuses. Using data collected through semi-structured interviews this study examines the various kinds of abuse that former Portuguese female gymnasts underwent during their sporting careers. Interviewees were asked to reflect on their past experiences and discuss aspects of the gymnastics subculture. Weight control, training/competing with injuries and corporal punishment emerged as key themes. The study therefore shows that the physical and psychological abuse of young athletes occurs even beyond the confines of elite professional sport, and thus that a broader spectrum of athletes learn to consider these forms of exploitation and abuse as normal.     

The value of a non-sport-specific motor test battery in predicting performance in young female gymnasts

Gymnastics talent identification focuses on the identification of young gymnasts who display characteristics for potential success in the future. The aim of this study was to identify which current performance characteristics are related to performance in competition 2 years later. Twenty-three female gymnasts aged 7-8 years completed a multidimensional test battery measuring anthropometric, physical, and coordinative characteristics and were technically evaluated by expert coaches. Two years later, the all-around competition results of those gymnasts now participating in elite (n = 12) and sub-elite (n = 11) competition were obtained. None of the initial measurements significantly correlated with the results of the sub-elite gymnasts 2 years later. For the elite gymnasts, a non-sport-specific motor test battery correlated strongly with the competition result, with more than 40% of the variation in competition performance being explained by the result on that test 2 years earlier. Neither the coaches' judgement nor the anthropometric and physical characteristics were sensitive enough to predict performance. A motor coordination test might be valuable in the early identification of gymnasts, as its discriminative and predictive qualities might be sufficiently powerful for selection within a relatively homogeneous population of gymnasts exhibiting similar anthropometric and physical profiles.     

Digit ratio (2D:4D) and competition level in world-class female gymnasts

Abstract

In this study the relationship between the digit ratio (2D:4D) and artistic gymnastics performance and competition level was investigated in a sample of Caucasian world-class female gymnasts (n = 145). The sample was divided into three competition events (compulsories, free work, final score). Within each event three performance groups (lowest, middle, and highest) were based on the competition scores gathered at the World Championships at Rotterdam, the Netherlands, in 1987. Lengths of the digits were measured on X-rays of the left hand. Several anthropometric dimensions were measured and from those measurements an androgyny index (Bayer & Bayley) and somatotype components (endomorphy, mesomorphy, ectomorphy) were calculated. Although significant differences in some anthropometric characteristics between the performance level groups within each competition event were observed, no significant differences in the 2D:4D ratios were found between the performance level groups, varying from 0.918 ± 0.020 to 0.924 ± 0.020. Also, no significant correlations were observed between the 2D:4D ratio and anthropometric, androgyny, and somatotype characteristics, r varying from r = –0.11 to r = +0.12. It can be concluded that in this sample the 2D:4D digit ratio, unlike other anthropometric characteristics, is not a discriminating factor for the performance in artistic gymnastics performance on a world-class level.     

Sport commitment and participation in masters swimmers: The influence of coach and teammates

Abstract

This study investigated how coach and teammates influence masters athletes' sport commitment, and the effect of functional and obligatory commitments on participation in masters swimming. The sample consisted of 523 masters swimmers (330 males and 193 females) aged between 22 and 83 years (M = 39.00, SD = 10.42). A bi-dimensional commitment scale was used to measure commitment dimensions and perceived influence from social agents. Structural equation modelling analysis was conducted to evaluate the influence of social agents on functional and obligatory commitments, and the predictive capabilities of the two types of commitment towards sport participation. Support provided by coach and teammates increased functional commitment, constraints from these social agents determined higher obligatory commitment, and coach constraints negatively impacted functional commitment. In addition, both commitment types predicted training participation, with functional commitment increasing participation in team training sessions, and obligatory commitment increasing the hours of individual training. The findings suggest that in order to increase participation in masters swimming teams and reduce non-supervised training, coach and teammates should exhibit a supportive attitude and avoid over expectation.     

Technique selection in young female gymnasts: Elbow and wrist joint loading during the cartwheel and round-off

Biophysical loading of the elbow and wrist is a potential reason for chronic lesions in gymnastics and present a real concern for coaches, scientist and clinicians. Previous research has identified injury risk factors during round-off (RO) skills in elite female gymnasts. The aim of this study was to investigate key elbow and wrist joint injury risk factors during different techniques of fundamental cartwheel (CW) and RO skills performed by young female artistic gymnasts. Seventeen active young female gymnasts performed 30 successful trials of both CW and RO from a hurdle step with three different hand positions (parallel (10), T-shape (10) and reverse (10)). Synchronised kinematic (240?Hz) and kinetic (1200?Hz) data were collected for each trial. One-way repeated measures ANOVA and effect size (ES) were used for statistical analysis. The results showed statistically significant differences (P?0.8) among hand positions for peak vertical ground reaction force (VGRF), peak elbow compression force, peak wrist compression force, elbow internal adduction moment and wrist dorsiflexion angle. In conclusion, the parallel and reverse techniques increase peak VGRF, elbow and wrist compression forces, and elbow internal adduction moment. These differences indicate that the parallel and reverse techniques may increase the potential of elbow and wrist injuries in young gymnasts compared with the T-shape technique; this is of particular importance with the high frequency of the performance of these fundamental skills.     

Political activity in escalation of commitment: Sport facility funding and government decision making in the United States

In the United States, the decision to commit extensive public resources to sport facilities is a contentious topic of debate. Elected officials often commit substantial public resources to sport facility projects amidst contrary empirical evidence and mixed residential approval. This behavior not only implicates the presence of political activity to advance a course of action, but also suggests an escalation of commitment (EoC), the subject of this study. The authors implemented a collective case study approach to examine three municipalities with long-standing histories of subsidizing professional sport facilities. Data collected from influential elected officials and public leaders (N = 13) as well as documents and records revealed (a) political action to be essential in EoC with decisions involving multiple stakeholder groups; (b) the influence and interaction of political action within each EoC determinant; (c) the substantial role of support, resources, power, and influence in efforts to increase and prevent commitment to a failing course of action; and (d) noticeable spillover effects from use of political activity in EoC.     

Sport: a scientific experiment?

Abstract

Science plays an increasingly important role in sport. Innovative high-tech equipment and research-based exercise regimes are vivid examples. In more subtle forms, scientific ways of thinking impact how sport is understood and practiced. I examine the possibilities and limits of scientific rationality in the set-up of competitive sport. Standard requirements on reliability and validity make sense when it comes to the quest for equal opportunity, and for fair and impartial evaluation of performance. However, whereas the instrumental aim of science is ‘certified’ knowledge, I argue that sport has primary meaning and value in itself. In further analysis of the normative structure of sport, an alternative ludic rationality emerges with elements of merit, chance and luck. I argue that sport is structured to cultivate not only athletic but human excellence. I conclude that upholding ludic rationality, operationalized in norms for fair play, is crucial for realizing sport’s characteristic values.
