This study examined the effectiveness of a logbook and paperclip technique on awareness of the use and content of negative self-talk as well as the motivation to change negative self-talk. Participants (n = 73) completed a questionnaire measuring these variables, and were assigned to either a control, paperclip or logbook group. Participants performed three typical training sessions over a three-week period. The logbook group completed a self-talk logbook after each session whereas the paperclip group carried out a paperclip exercise during each session. Upon completion of the training sessions, the questionnaire was readministered. ANCOVAs revealed no significant differences between the groups for motivation to change and awareness of the content of negative self-talk. However, the logbook group had significantly greater awareness of their use of negative self-talk compared with the control group. A qualitative analysis of the logbook group’s use of negative self-talk provided insights into the situations that prompted negative self-talk, the content of the self-talk, and also the consequences of using negative self-talk. Collectively, the findings offer some support for the use of the logbook technique in the applied setting.

This study investigated whether force data could be derived accurately using segment inertia data determined by the elliptical zone method (Jensen, 1976), automatic digitizing from high-speed video using a Motion Analysis VP110 system, and for an activity that does not require flexion of the thorax. The criterion fonctions were the force-time records of the jumps recorded at 500 Hz by a Kistler 9281B force platform. A second-order Butterworth digital filter was used to smooth the derived data, with frequency cutoffs being selected on the basis of root mean square error of the smoothed function with respect to the criterion force function. In a second procedure, the criterion function was the directly measured force-time record after filtering with a second-order Butterworth digital filter at 5 Hz to remove the high frequency part of the force signal. The closeness of fit of the derived data to the low frequency part of the criterion force was then assessed. It was concluded that, using the techniques described, the low frequency components of the ground reaction forces of drop jumps could be derived accurately.

Two studies examined the interactive effects of different visual imagery perspectives and narcissism on motor performance. In both studies participants completed the Narcissistic Personality Inventory (NPI-40: Raskin & Hall, 1979) and were assigned to either an internal visual imagery or external visual imagery group. Participants then performed a motor task (dart throwing in Study 1 and golf putting in Study 2) under conditions of practice, low self-enhancement, and high self-enhancement. Following completion of the respective tasks, participants were categorized into high and low narcissistic groups based on their NPI-40 scores. In both studies, high narcissists using external visual imagery significantly improved performance from the low to the high self-enhancement condition, whereas high narcissists using internal visual imagery did not. Low narcissists remained relatively constant in performance across self-enhancement conditions, regardless of perspective. The results highlight the importance of considering personality characteristics when examining the effects of visual imagery perspectives on performance.

Despite a plethora of research on moral disengagement and antisocial behavior, there is a dearth of literature that explores personality in the context of these undesirable attitudes and behaviors. We provide the first examination of personality, specifically narcissism, as a predictor of moral disengagement and antisocial behavior in sport. Given that narcissism is negatively related to empathy and positively related to feelings of entitlement, it is more likely for narcissists to disengage morally and to behave antisocially. We thus hypothesized that narcissism would predict antisocial behavior via moral disengagement. Across 12 team contact sports (n = 272), bootstrapped mediation analyses confirmed this indirect effect, which remained significant when controlling for motivational climate, social desirability, sex and sport type. Coaches and practitioners would do well to consider the darker side of personality in targeting moral disengagement and its behavioral consequences in team sports.

Recent brain imaging research demonstrates that the use of internal visual imagery (IVI) or kinesthetic imagery (KIN) activates common and distinct brain areas. In this paper, we argue that combining the imagery modalities (IVI and KIN) will lead to a greater cognitive representation (with more brain areas activated), and this will cause a greater slalom-based motor performance compared with using IVI alone. To examine this assertion, we randomly allocated 56 participants to one of the three groups: IVI, IVI and KIN, or a math control group. Participants performed a slalom-based driving task in a driving simulator, with average lap time used as a measure of performance. Results revealed that the IVI and KIN group achieved significantly quicker lap times than the IVI and the control groups. The discussion includes a theoretical advancement on why the combination of imagery modalities might facilitate performance, with links made to the cognitive neuroscience literature and applied practice.

Two studies explored coach education imagery interventions. In Study 1, 29 performance coaches were randomly assigned to either an imagery workshop group (n = 13) or an imagery-reading comparison control group (n = 16). Pre and post intervention, coaches completed the CEAIUQ (Jedlic, Hall, Munroe-Chandler, & Hall, 2007) and a confidence questionnaire designed for the study. Further, coaches’ athletes completed the CIAIUQ (Jedlic et al., 2007) at pre and post intervention. Due to a poor response rate (n = 9), an exploratory case study approach was employed to present the data. Results revealed that, while all coaches found the workshop to be interesting and useful, with certain coaches, encouragement of specific aspects of imagery decreased as did confidence to deliver imagery. To overcome the limitations of Study 1, Study 2 employed a needs based approach. Five elite coaches completed a performance profile related to imagery and the CEAIUQ. Four individualized sessions were then conducted. Inspection of post intervention data indicated that the intervention increased encouragement of imagery use, imagery constructs identified as important by the individual coaches, and, when identified, confidence to deliver imagery. The results are discussed in terms of the importance of coach education from both an applied and research perspective.

The present investigation examined whether perfectionism might predict whether an athlete would suffer from the ‘yips’ (a long term movement disorder consisting of involuntary movements that affects the execution of motor skills). A sample of ‘yips’-affected individuals from golf, cricket, and darts as well as a sport-matched sample of non ’yips’-affected athletes completed the shortened version of Frost, Marten, Lahart, and Rosenblate’s (1990) multidimensional perfectionism scale (FMPS). Results revealed that three aspects of perfectionism (personal standards, organization, and concern over mistakes) were associated with a greater likelihood of suffering from the ‘yips’, indicating that ‘yips’ sufferers had an unhealthy perfectionism profile. The results highlight perfectionism as a possible antecedent of the ‘yips’ experience within sport.

T o determine differences between contralateral limbs’ strength, proprio-ception, and kinetic and knee-kinematic variables during single-limb landing.
Hip, knee, and foot isokinetic peak torques; anterior/posterior (AP) and medial/lateral (ML) sway displacements during a balance task; and stabilization times, vertical ground-reaction force (VGRF), time to peak VGRF, and knee-flexion range of motion (ROM) from initial foot contact to peak VGRF during single-limb landing.
The kicking limb had significantly greater values for knee-extension (P = .008) and -flexion (P = .047) peak torques, AP sway displacement (P = .010), knee-flexion ROM from initial foot contact to peak VGRF (P < .001), and time to peak VGRF (P = .004). No other dependent measures were significantly different between limbs (P > .05).
The kicking limb had superior thigh strength, better proprioception, and greater knee-flexion ROM than the stance limb.

One hundred forty-six abdominally obese adults age 60–80 yr were studied to investigate the interaction between cardiorespiratory fitness (CRF) and obesity on functional limitation. Obesity was determined by fat mass (FM), CRF was determined by a maximal treadmill test, and functional limitation was based on 4 different tasks that are predictive of subsequent disability. Both FM (r = –.34, p ≤ .01) and CRF (r = .54, p ≤ .01) were independently associated with functional limitation in bivariate analysis. After further control for sex, age, and the interaction term (CRF × FM), FM was no longer independently associated with functional limitation (p = .10). Analyses were also based on sex-specific tertiles of FM and CRF. The referent group demonstrated significantly lower functional limitation than the low-CRF/low-FM and the low-CRF/high-FM groups (both p ≤ .05). These results highlight the value of recommending exercise for abdominally obese adults.

This study is part of a program of research investigating coaches delivering psychological skills (PS). Here, 3 studies feature an original conceptualization of coaching PS and the development and validation of 2 questionnaires capturing the coaching of PS. The authors conducted a qualitative investigation to establish a conceptual framework that included the fundamental coaching of PS behaviors (CPS-F) and the needs-supportive coaching of PS (CPS-NS). They then tested the factor structure of 2 subsequently developed questionnaires via a Bayesian structural equation modeling approach to confirmatory factor analysis across 2 samples and ran tests of invariance, concurrent, discriminant, and predictive validity. The CPS-F questionnaire showed an excellent fit for a 3-factor model, whereas the CPS-NS demonstrated an excellent single-factor fit. Significant relationships with theoretically related constructs suggested concurrent, discriminant, and predictive validity. The findings are expected to significantly further research into our understanding of coaches coaching PS.
