The focus of this prospective, observational study was to determine the effect of sport-specific training and calcium intake on bone mineral density (BMD) in female master cyclists, runners and non-athletes. Thirty women (12 cyclists, 9 runners, 9 controls), mean age of 49.6 ±7.9 years, were assessed at baseline and 18 months for calcium intake (4-day records), current exercise activity (recall questionnaire), and BMD of the lumbar spine and hip (DXA). A three (cyclists, runners, controls) by two (0 and 18 months) repeated measures ANOVA demonstrated a significant interaction effect of sport and time at the femoral neck (p < .04). Tukey post hoc analysis indicated that the BMD of the femur was maintained in cyclists and runners but declined in controls (p < .05). A significant time effect was noted in BMD at the lumbar spine (p < .001) and the trochanter (p < .003). BMD of the lumbar spine was maintained in runners but declined in cyclists (p < .007) and in controls (p < .03), while trochanteric BMD declined in all groups (p < .01). No significant interaction effect of sport and dietary calcium intake was noted for BMD at any site.

Female boxing debuted at the 2012 London Olympic Games. To better understand the performance aspects of the sport, video footage of eighteen 4 × 2-min bouts were analyzed. The boxers involved in the competition were of an elite level (mean ± SD), age 26.4 ± 4.6 y, height 169.3 ± 6.2 cm, and weight 60.3 ± 10.0 kg. Analysis revealed an activity rate of ~1.6 actions/s, including ~16 punches, ~3.3 defensive movements, and ~63 vertical hip movements, all per minute, over the 4 × ~132-s rounds (R). A 2 × 4 (outcome × round) ANOVA with repeated measures over the rounds was used to analyze the data. Winners maintained a higher activity rate in round 1 (R1) and R2; a higher movement rate in R2, R3, and R4; and an increased punch accuracy including the ratio of total punches to punches landed in R3 and air punches as a percentage of punches missed in R1 and R3. Specific techniques that discriminate between successful and unsuccessful female amateur boxers include the straight rear-hand and body punches, higher for winners in R1, as well as uppercut punches and defensive foot movements, higher for winners in R4. Findings highlight the current demands of elite amateur female boxing. These data will be useful for those designing training programs and may also be useful for guiding sport-specific fitness testing.

The present preliminary study aimed to develop and examine the psychometric properties of a new sport-specific self-report instrument designed to assess athletes’ and coaches’ attachment styles. The development and initial validation comprised three main phases. In Phase 1, a pool of items was generated based on pre-existing self-report attachment instruments, modified to reflect a coach and an athlete’s style of attachment. In Phase 2, the content validity of the items was assessed by a panel of experts. A final scale was developed and administered to 405 coaches and 298 athletes (N = 703 participants). In Phase 3, confirmatory factor analysis of the obtained data was conducted to determine the final items of the Coach-Athlete Attachment Scale (CAAS). Confirmatory factor analysis revealed acceptable goodness of ft indexes for a 3-first order factor model as well as a 2-first order factor model for both the athlete and the coach data, respectively. A secure attachment style positively predicted relationship satisfaction, while an insecure attachment style was a negative predictor of relationship satisfaction. The CAAS revealed initial psychometric properties of content, factorial, and predictive validity, as well as reliability.

Balance and anaerobic performance are key attributes related to horse-racing performance, but research on the impact of making weight for racing on these parameters remains unknown. The purpose of this study was to investigate the effects of rapid weight loss in preparation for racing on balance and anaerobic performance in a group of jockeys.


Twelve apprentice male jockeys and 12 age- and gender-matched controls completed 2 trials separated by 48 h. In both trials, body mass, hydration status, balance, and anaerobic performance were assessed. Between the trials, the jockeys reduced body mass by 4% using weight-loss methods typically adopted in preparation for racing, while controls maintained body mass through typical daily dietary and physical activity habits.


Apprentice jockeys decreased mean body mass by 4.2% ± 0.3% (P < .001) with a subsequent increase in dehydration (P < .001). The controls maintained body mass and a euhydrated state. No differences in balance, on the left or right side, or in peak power, mean power, or fatigue index were reported between the trials in either group.


Results from this study indicate that a 4% reduction in body mass in 48 h through the typical methods employed for racing, in association with an increase in dehydration, resulted in no impairments in balance or anaerobic performance. Further research is required to evaluate performance in a sport-specific setting and to investigate the specific physiological mechanisms involved.

Attribution of causality, based on Rotter's (1966) and Weiner's (1979) models, was investigated in a sport setting. The Wingate Sport Achievement Responsibility Scale (WSARS) was developed in order to examine attribution of causality separately for individual and team athletes after successful and unsuccessful events. The scale included feedback from the coach, audience, and teammates. Additional attributions were added in order to examine sport related properties of attributions. In order to examine the distinction between sport-specific attributions and general locus of control (LOG), 69 team athletes and 38 individual athletes were administered the Rotter I-E LOG Scale and the WSARS (Tenenbaum & Weingarten, 1983). Both Rotter's Scale and the WSARS were found to be reliable and valid scales through the probabilistic Rasch Model. Correlational analysis of both scales showed that attribution of causality in team and individual sports were positively related but produced low correlations, which suggests that sport attribution should be examined separately from general LOG. In addition, successful events should be examined separately from unsuccessful events and a distinction should be made between individual and team athletes.

In this exploratory investigation of competitive orientations, intercollegiate athletes from a highly competitive Division I program and nonathletes from the same university completed Gill’s Sport Orientation Questionnaire (SOQ) which assesses competitiveness, win and goal orientation; Vealey’s Competitive Orientation Inventory (COI) which assesses the relative importance of performing well (performance) and winning (outcome) in competitive sports; and Helmreich and Spence’s Work and Family Orientation Questionnaire (WOFO), a general achievement orientation measure. A Gender × Athlete/Nonathlete MANOVA yielded both gender and athlete/nonathlete main effects and no interaction. The gender difference was most evident for competitiveness scores, with males scoring higher than females on competitiveness and win orientation. Athletes scored higher than nonathletes on most measures, but especially so on the sport-specific competitiveness score. Athletes also placed more emphasis on performance and less on outcome than nonathletes did. A secondary analysis compared the eight athletic teams and revealed considerable variation among teams. Generally the team differences were not gender differences but seemed to reflect the competitive structure of the activity.

It is generally recognized that athletes differ in their ability to function with pain following injury. In an effort to measure this differing ability, the Sports Inventory for Pain (SIP) was developed using input from injured athletes, a college student sample, and information generated through the pain research literature. The SIP consists of 25 items that identify five pain subscales (coping, cognitive, avoidance, catastrophizing, and body awareness) and a composite score (HURT). Cronbach's coefficient alpha levels, ranging from .88 to .61, confirmed internal consistency reliability. Test-retest reliability coefficients ranged from .69 to .88. ANOVA and subsequent post hoc analyses that compared groups (categorized by number of injuries, years of sport participation, and number of sports played) on each subscale and on the composite promise satisfactory validity. Pearson correlations between social desirability and the SIP subscales were nonsignificant (p>.05; n=39), ranging from −.06 to .22. The SIP serves as a sport-specific measure of an athlete's capacity to perform while in pain. Further research aimed at establishing its validity is warranted.

Harter's (1979) perceived competence subscale was modified to specifically apply to soccer in order to compare young soccer players' general self-esteem, perceived physical competence, and perceived soccer competence scores in predicting players' actual soccer ability. Young soccer players (N = 217), 8 to 13 years of age, were tested on five soccer skill tests. Players also completed Harter's (1979) Perceived Competence Scale for Children and our perceived soccer competence subscale. We hypothesized that perceived soccer competence would have high internal consistency and would be a better predictor of soccer ability than either perceived physical competence or general self-esteem. Results indicated that the perceived soccer competence subscale had the highest internal consistency reliability coefficient, and that it was also slightly more predictive of soccer ability than perceived physical competence as indicated by multivariate multiple regression analysis and canonical correlation analysis. Future studies investigating perceived competence as a motivational variable in specific youth sports may find the sport-specific perceived competence measure to provide additional information to Harter's questionnaire.

Despite the growing interest in Paralympic sport, the evidence base for supporting elite wheelchair sport performance remains in its infancy when compared with able-bodied (AB) sport. Subsequently, current practice is often based on theory adapted from AB guidelines, with a heavy reliance on anecdotal evidence and practitioner experience. Many principles in training prescription and performance monitoring with wheelchair athletes are directly transferable from AB practice, including the periodization and tapering of athlete loads around competition, yet considerations for the physiological consequences of an athlete’s impairment and the interface between athlete and equipment are vital when targeting interventions to optimize in-competition performance. Researchers and practitioners are faced with the challenge of identifying and implementing reliable protocols that detect small but meaningful changes in impairment-specific physical capacities and on-court performance. Technologies to profile both linear and rotational on-court performance are an essential component of sport-science support to understand sport-specific movement profiles and prescribe training intensities. In addition, an individualized approach to the prescription of athlete training and optimization of the “wheelchair–user interface” is required, accounting for an athlete’s anthropometrics, sports classification, and positional role on court. In addition to enhancing physical capacities, interventions must focus on the integration of the athlete and his or her equipment, as well as techniques for limiting environmental influence on performance. Taken together, the optimization of wheelchair sport performance requires a multidisciplinary approach based on the individual requirements of each athlete.

The purpose of this study was to describe running economy, soccer specific endurance, and selected kinematic running criteria in soccer players with cerebral palsy (SPCP) and to compare them with values of position-matched players without CP. Fourteen international, male soccer players with cerebral palsy completed the “Yo-Yo” intermittent recovery run level 1 (IRL-1) test to assess soccer-specific endurance and a submaximal running test on a treadmill to determine running economy. The mean IRL-1 distance covered by the SPCP of the Irish CP team was found to be 43–50% below the mean distance attained by position-matched soccer players without disability, while running economy was found to be within the range of that reported for able-bodied athletes. No relationship could be found between the level of CP-ISRA classification and soccer-specific endurance or running economy in this group of elite level SPCP. Though small in number, these data support a further examination of the relationship between CP classification and sport-specific performance.
