Doping use is an ongoing problem in contemporary sports. Despite efforts to detect and control doping, research on its etiology is limited, especially among elite-level athletes. The present study used an integrated social cognition model to examine the predictors of doping intentions. Structured anonymous questionnaires were completed by 1075 Greek adult elite-level athletes (M age = 25 years, SD = 5.89, 36.1% females) from both team and individual sports. Multiple regression and mediation analyses showed that attitudes, normative beliefs, situational temptation, and behavioral control significantly predicted doping intentions. A normative process was identified whereby situational temptation mediated the effects of normative beliefs on intentions. The findings provide the basis for future social cognition research in doping use, and set the framework for the development of evidence-based preventive interventions.

This study used time-varying effect modeling to examine time-of-day differences in how behavioral cognitions predict subsequent physical activity (PA). Adults (N = 116) participated in three 4-day “bursts” of ecological momentary assessment (EMA). Participants were prompted with eight EMA questionnaires per day assessing behavioral cognitions (i.e., intentions, self-efficacy, outcome expectations) and wore an accelerometer during waking hours. Subsequent PA was operationalized as accelerometer-derived minutes of moderate- or vigorousintensity PA in the 2 hr following the EMA prompt. On weekdays, intentions positively predicted subsequent PA in the morning (9:25 a.m.–11:45 a.m.) and in the evening (8:15 p.m.–10:00 p.m.). Self-efficacy positively predicted subsequent PA on weekday evenings (7:35 p.m.–10:00 p.m.). Outcome expectations were unrelated to subsequent PA on weekdays. On weekend days, behavior cognitions and subsequent PA were unrelated regardless of time of day. This study identifies windows of opportunity and vulnerability for motivation-based PA interventions aiming to deliver intervention content within the context of adults’ daily lives.

Dementia cases are on the rise and researchers seek innovative ways to prevent or ameliorate cognitive impairment in later life. Some research has reported that combining mental and physical exercise may benefit cognition more than either alone. This randomized pilot trial examined the feasibility and cognitive benefit for older adults (n = 30) of a single bout of neuro-exergaming (physical activity with cognitive training) using an interactive physical and cognitive exercise system (iPACES), compared with that of exergaming or neurogaming alone. Intent-to-treat and sensitivity analyses were conducted using repeated-measures ANOVA, controlling for age, sex, and education. A significant interaction effect was found for executive function (Color Trails 2), with a significant improvement in the neuro-exergaming condition. Results demonstrate feasibility for older adults to use a novel and theoretically-derived neuro-exergame, and also provide promising new evidence that neuro-exergaming can yield greater cognitive benefit than either of its component parts.

The objective of the studies presented in this paper was to examine whether the need to belong can be used to enhance exercise cognitions and behavior. Two studies examined the effectiveness of framing exercise as a means of boosting social skills (versus health benefits) for self-regulatory efficacy, exercise intentions, and (in Study 2) exercise behavior. In Study 1, inactive adults primed to feel a lack of social belonging revealed that this manipulation led to greater self-regulatory efficacy (but not exercise intentions). In Study 2, involving a sample of inactive lonely adults, all participants reported engaging in more exercise; however, those in the social skills condition also reported a greater sense of belonging than those in the health benefits comparison condition. These findings provide an important basis for developing physical activity interventions that might be particularly relevant for people at risk for feeling socially isolated or lonely.
In exercise and cognition research, few studies have investigated whether and how the qualitative aspects of physical exercise may impact cognitive performance in the short or long term. This commentary, after recalling the evidence on the “dose-response” relationship, shifts the focus to intersections between different research areas that are proposed to shed light on how qualitative exercise characteristics can be used to obtain cognitive benefits. As concerns the acute exercise area, this commentary highlights the applied relevance of developmental and aging studies investigating the effects of exercise bouts differing in movement task complexity and cognitive demands. As regards the chronic exercise area, potential links to research on cognitive expertise in sport, functional ability in aging, and life skills training during development are discussed. “Gross-motor cognitive training” is proposed as a key concept with relevant implications for intervention strategies in childhood and older adulthood.

The aim of this meta-analysis was to examine the magnitude of the relationship between social influence and both PA behavior and PA-related social cognitions among samples of adults with physical disabilities, including those with chronic conditions that can lead to a physical disability. A comprehensive literature search was conducted to identify studies involving adults with physical disability, a measure of social influence, and a measure of PA behavior or PA-related social cognitions. A total of 27 studies with 4,768 participants yielded 47 effect sizes to be included for meta-analysis. Significant, small- to medium-sized relationships were identified between social influence and PA behavior, and social influence and PA-related social cognitions. These relationships suggest that social factors positively associate with physical-activity-related social cognitions and should be targeted when promoting physical activity behavior change among adults with a physical disability.

No previous studies have explored the effects of mind–body approaches on health-related quality of life (HRQoL) in the frail elderly. Cognition and action are an inseparable whole during functioning. Thus, a new intervention-based approach using familiarity-based movements and a nonjudgmental approach of “cognition-action” was proposed and was tested with Tai Chi on HRQoL in frail institutionalized elderly. Fifty-two participants (58% women) age 65–94 took part in a 24-wk Tai Chi (TC) intervention 4 days/wk or a cognition-action (CA) exercise program of 30 min twice a week. Changes in Mini Mental State score, physical (PCS) and mental component (MCS) summaries (SF12); Falls Efficacy Scale (FES); and exercise self-efficacy were explored. PCS improved from 33.6 ± 6.7 to 51 ± 4.8 in the TC group and from 30.6 ± 9.9 to 45.1 ± 10.2 in the CA group (p < .001). MCS of SF-12 (p < .001), FES (p < .001), and exercise self-efficacy (p < .01) were enhanced significantly in both groups. Adapted CA programs and Tai Chi were both efficient in improving HRQoL of frail elderly.

Falls can impair health and reduce quality of life among older adults. Although many factors are related to falling, few analyses examine causal models of this behavior. In this study, factors associated with falling were explored simultaneously using structural-equation modeling. A variety of cognitive, physical-performance, and health measures were administered to 694 older adult drivers from the state of Maryland. The observed and latent variables of age, cognitive ability, physical functioning, health, and falling behavior were used to create a causal model. The model revealed that being older was associated with declines in cognition, and such cognitive declines predicted increased falling. Similarly, poorer health was related to poorer physical functioning, which, in turn, also predicted increased falling. This model indicates that in addition to existing fall-prevention interventions aimed at improving physical functioning, interventions to improve cognition and health might also be effective. It is speculated that fear of falling, which often results in reduced mobility among older adults, might account for the lack of a direct relationship between age and falling. This hypothesis should be examined in further research.
