Forthcoming events

The aim of this study was to examine mental imagery within the context of the deliberate practice framework. Altogether, 159 athletes from one of three different competitive standards (recreational, provincial and national) completed the Deliberate Imagery Practice Questionnaire, which was designed for the present study to assess the athletes' perceptions of the importance of imagery along the three deliberate practice dimensions of relevancy, concentration and enjoyment. The results indicated that national athletes perceived imagery to be more relevant to performing than recreational athletes. In addition, athletes of a higher standard (i.e. provincial and national) reported using more imagery in a recent typical week and they had accumulated significantly more hours of imagery practice across their athletic career than recreational athletes. Finally, the relationships among the dimensions of deliberate practice did not lend conclusive support to either the original conception of deliberate practice or a sports-specific framework of deliberate practice.     

A comparison of the physiological response to simulated altitude exposure and r-HuEpo administration

Concerns have been raised about the morality of using simulated altitude facilities in an attempt to improve athletic performance. One assumption that has been influential in this debate is the belief that altitude houses simply mimic the physiological effects of illegal recombinant human erythropoietin (r-HuEpo) doping. To test the validity of this assumption, the haematological and physiological responses of 23 well-trained athletes exposed to a simulated altitude of 2650-3000 m for 11-23 nights were contrasted with those of healthy volunteers receiving a low dose (150 IU·kg^-1 per week) of r-HuEpo for 25 days. Serial blood samples were analysed for serum erythropoietin and percent reticulocytes; maximal oxygen uptake ([Vdot]O_2max) was assessed before and after r-HuEpo administration or simulated altitude exposure. The group mean increase in serum erythropoietin (422% for r-HuEpo vs 59% for simulated altitude), percent reticulocytes (89% vs 30%) and [Vdot]O_2max (6.6% vs -2.0%) indicated that simulated altitude did not induce the changes obtained with r-HuEpo administration. Based on the disparity of these responses, we conclude that simulated altitude facilities should not be considered unethical based solely on the tenet that they provide an alternative means of obtaining the benefits sought by illegal r-HuEpo doping.     

Performers' responses to stressors encountered in sport organisations

Abstract

We investigated athletes' responses to organisational stressors. Ten sport performers (five males and five females) were interviewed with regard to the organisational-related demands they had encountered and their responses to these stressors. The main emotional responses that were revealed were anger, anxiety, disappointment, distress, happiness, hope, relief, reproach and resentment. The main attitudinal responses were beliefs, motivation and satisfaction. The main behavioural responses were categorised as verbal and physical. The data indicate that performers generally respond to organisational stressors with a wide range of emotions, attitudes and behaviours. The findings are discussed in relation to the extant literature and in terms of their implications for applied practice and future research. Consultants should employ reactive strategies alongside proactive approaches to ensure that performers are psychologically prepared to manage and cope with any demands that are not eliminated. Future research should focus on performers' cognitive appraisals of the organisational stressors they encounter.     

Acute and residual effects of vibratory stimulation on explosive strength in elite and amateur athletes

Fourteen elite and 14 amateur athletes were subjected to vibratory stimulation during bilateral biceps curl exercises of explosive strength exertion. The athletes performed two separate series of three sets of exercises in random order. The second set of one series was administered with superimposed vibration of 44 Hz and an acceleration of about 30 m .s-2 transmitted through the two-arms handle to the arm muscles. The mechanical power of each repetition was measured by the ‘Power Teach’ instrument. The maximal and mean power values for each set were automatically recorded and shown on the screen. The acute effect was evaluated as the difference between the mean and peak power output in the second (with vibratory stimulation) and first (without vibratory stimulation) sets. Similarly, the residual effect was taken to be the difference between the power values of the third (after vibratory stimulation) and the first (before vibratory stimulation) sets. The results were subjected to a repeated-measures analysis of variance with group as a between-participants factor. The results showed that exercise mode (with vs without vibratory stimulation) resulted in a significant immediate effect for mean power and for maximal power. The factor group (elite vs amateurs) resulted in a significant effect for maximal power only. The increase in explosive strength exertion attributed to vibratory stimulation was 30.1 and 29.8 W (10.4% and 10.2%) for maximal and mean power respectively in the elite group, and 20.0 and 25.9 W (7.9% and 10.7%) respectively in the amateur athletes. Vibratory stimulation resulted in an insignificant residual effect.     

The attitudes and opinions of high school sports participants: an exploratory empirical examination

Sport scholars and public commentators have long held both positive and critical opinions about the influence of athletic involvement on participants and their perceptions of the social world. Yet for all of the strong claims and deeply held assumptions, relatively little empirical data or social scientific analysis have been available. This study begins to address this deficiency using new data from a nationally representative survey of American high school students. We compare sports participants and their peers in terms of concern for social problems, interracial contact and attitudes, views of gender roles and sex-based discrimination and political orientation. We find participants and non-participants differ very little in their social concern and views of gender roles and sex-based discrimination, while significant differences were found in levels of interracial contact, views on race relations and political orientation. In view of these findings, we make some general conclusions about the social influence of sport in the lives of American youth and how this topic may be further explored in subsequent work.     

Family contributions to sport performance and their utility in predicting appropriate referrals to mental health optimization programmes

ABSTRACT

Limited research has examined the contributions of sport-specific family relationship problems to athlete mental health. In the current study we examined the extent to which collegiate athletes’ family problems (as measured by the Student Athlete Relationship Instrument factors, SARI) predict athletes’ general mental health distress and specific mental health symptoms that are relatively common in athletes (i.e. depression, anxiety, and drug and alcohol use). The study included 85 collegiate athletes (intramural, n?=?26; club sport, n?=?12; NCAA Division I, n?=?47). We hypothesized that both general mental health distress and commonly evidenced mental health symptoms would be predicted by athletes’ responses to the SARI factors (Poor Relationship and Lack of Support, General Pressure, Pressure to Quit or Continue Unsafely, Embarrassing Comments, and Negative Attitude). Results indicated that all of the aforementioned SARI factors predicted athletes’ ratings of depression and general mental health distress levels. Only the General Pressure SARI factor predicted athletes’ anxiety and drug use. Alcohol use was not predicted by any of the SARI factors. Receiver operating characteristic (ROC) analyses indicated that sport-specific problems in family relationships provided a good classification of athletes at risk for general mental health distress, depression, and anxiety. Practice implications are discussed in light of the results.
