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.

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.

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.

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.

The purpose of this research was to amend the Vividness of Movement Imagery Questionnaire (VMIQ; Isaac, Marks, & Russell, 1986) in line with contemporary imagery modality and perspective conceptualizations, and to test the validity of the amended questionnaire (i.e., the VMIQ-2). Study 1 had 351 athletes complete the 3-factor (internal visual imagery, external visual imagery, and kinesthetic imagery) 24-item VMIQ-2. Following single-factor confirmatory factor analyses and item deletion, a 12-item version was subject to correlated traits / correlated uniqueness (CTCU) analysis. An acceptable fit was revealed. Study 2 used a different sample of 355 athletes. The CTCU analysis confirmed the factorial validity of the 12-item VMIQ-2. In Study 3, the concurrent and construct validity of the VMIQ-2 was supported. Taken together, the results of the 3 studies provide preliminary support for the revised VMIQ-2 as a psychometrically valid questionnaire.

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.

Narcissism–performance research has focused on grandiose narcissism but has not examined the interaction between its so-called adaptive (reflecting overconfidence) and maladaptive (reflecting a domineering orientation) components. In this research, the authors tested interactions between adaptive and maladaptive narcissism using two motor tasks (basketball and golf in Experiments 1 and 2, respectively) and a cognitive task (letter transformation in Experiment 3). Across all experiments, adaptive narcissism predicted performance under pressure only when maladaptive narcissism was high. In the presence of maladaptive narcissism, adaptive narcissism also predicted decreased pre-putt time in Experiment 2 and an adaptive psychophysiological response in Experiment 3, reflecting better processing efficiency. Findings suggest that individuals high in both aspects of narcissism perform better under pressure thanks to superior task processing. In performance contexts, the terms “adaptive” and “maladaptive”—adopted from social psychology—are oversimplistic and inaccurate. The authors believe that “self-inflated narcissism” and “dominant narcissism” are better monikers for these constructs.

Vallerand et al. (2003) developed a dualistic model of passion, wherein two types of passion are proposed: harmonious (HP) and obsessive (OP) passion that predict adaptive and less adaptive interpersonal outcomes, respectively. In the present research, we were interested in understanding the role of passion in the quality of coach–athlete relationships. Results of Study 1, conducted with athletes (N = 157), revealed that HP positively predicts a high-quality coach–athlete relationship, whereas OP was largely unrelated to such relationships. Study 2 was conducted with coaches (N = 106) and showed that only HP positively predicted the quality of the coach–athlete relationship. Furthermore, these effects were fully mediated by positive emotions. Finally, the quality of the coach–athlete relationship positively predicted coaches’ subjective well-being. Future research directions are discussed in light of the dualistic model of passion.

Context: It is debated whether running biomechanics make good predictors of running economy, with little known about the neuromuscular and joint-stiffness contributions to economical running gait. Purpose: To understand the relationship between certain neuromuscular and spatiotemporal biomechanical factors associated with running economy. Methods: Thirty trained runners performed a 6-min constant-speed running set at 3.3 m·s−1, where oxygen consumption was assessed. Overground running trials were also performed at 3.3 m·s−1 to assess kinematics, kinetics, and muscle activity. Spatiotemporal gait variables, joint stiffness, preactivation, and stance-phase muscle activity (gluteus medius, rectus femoris, biceps femoris, peroneus longus, tibialis anterior, and gastrocnemius lateralis and medius) were variables of specific interest and thus determined. In addition, preactivation and ground contact of agonist–antagonist coactivation were calculated. Results: More economical runners presented with short ground-contact times (r = .639, P < .001) and greater stride frequencies (r = −.630, P < .001). Lower ankle and greater knee stiffness were associated with lower oxygen consumption (r = .527, P = .007 and r = .384, P = .043, respectively). Only lateral gastrocnemius–tibialis anterior coactivation during stance was associated with lower oxygen cost of transport (r = .672, P < .0001). Conclusions: Greater muscle preactivation and biarticular muscle activity during stance were associated with more economical runners. Consequently, trained runners who exhibit greater neuromuscular activation prior to and during ground contact, in turn optimizing spatiotemporal variables and joint stiffness, will be the most economical runners.
