Background: To provide information regarding injury incidence, injury pattern, and associated injury risk factors in elite Paralympic judokas. Methods: Participants in this observational research were elite judokas taking part in the IBSA 2018 World Judo Championship. The entire championship was videotaped, and all injuries were prospectively documented using an all-complaints definition. Results: The tournament featured 267 judokas, (B1 = 58; B2 = 105; B3 = 104). The injury proportion was estimated at 18.9 injuries/100 fighters (B1 = 13.8; B2 = 22.3; B3 = 18.5). A total of 745 athletic exposures were registered. The overall injury rate was 68.5 (95% CI, 52.5–89.2); 62.5 (95% CI, 32–122.3); 79.6 (95% CI, 53.8–17.8); and 61.2 (95% CI, 40–93.5) for the total sample, B1, B2, and B3 judokas, respectively. When only injuries resulting in medical attention were analyzed, the overall injury rate was calculated to be 22.8 (95% CI, 14.3–36.5), and the injury proportion was estimated at 6.3 injuries/100 fighters. No significant differences were found for sex, weight, and visual class regarding injury proportion and injury rates. Conclusion: Paralympic judokas show a high injury rate. However, when only injuries that needed medical attention were taken into account, the proportion of athletes injured was low. The degree of visual impairment was not considered as an injury risk factor.

Adults with serious mental illness engage in limited physical activity, which contributes to significant health disparities. This study explored the use of both ecological momentary assessments (EMAs) and activity trackers in adults with serious mental illness to examine the bidirectional relationship between activity and affect with multilevel modeling. Affective states were assessed up to seven times per day using EMA across 4 days. The participants (n = 20) were equipped with a waist-worn accelerometer to measure moderate to vigorous physical activity. The participants had a mean EMA compliance rate of 88.3%, and over 90% of completed EMAs were matched with 30-min windows of accelerometer wear. The participants who reported more positive affect than others had a higher probability of engaging in moderate to vigorous physical activity. Engaging in more moderate to vigorous physical activity than one’s usual was associated with more negative affect. This study begins to address the effect of momentary mood on physical activity in a population of adults that is typically difficult to reach.

Prior research showed that swimmers swim faster in relay than in individual competitions if they start at later relay positions. This finding is typically explained via the swimmers’ relay position and their associated perception that their individual performance is indispensable for their teams’ performance. Using multilevel modeling, the authors disentangled this situational explanation from alternative accounts focusing on individual differences between swimmers. Two studies empirically supported the situational explanation: When using a within-person approach and, thus, controlling for between-person variance (i.e., individual differences between swimmers), the swimmers’ relay position remained a significant predictor of the increases in effort spent in relays. This finding held when controlling for the on-average higher instrumentality in the relay versus the individual competitions. Thus, the often observed effort gains in swimming relays probably are due to the swimmers’ relay position as a situational explanation and stem from the motivating impact of teamwork versus individual work.

This study examined the effects of perceptions of motor abilities on aerobic and musculoskeletal exercise performance in young children at risk for developmental coordination disorder (rDCD). The participants (N = 539) were part of a larger cohort study, the Coordination and Activity Tracking in Children (CATCH) study. The Movement Assessment Battery for Children (2nd Edition) was used to determine rDCD children. Perceptions of motor abilities were measured by the Perceived Efficacy and Goals Setting system. Aerobic exercise performance was measured using the Bruce Protocol treadmill test, and musculoskeletal exercise performance was assessed using the standing long jump and the Wingate Anaerobic test. The rDCD children reported lower Perceived Efficacy and Goals Setting scores and performed worse on all exercise performance measures. Perceptions of ability also mediated the relationship between developmental coordination disorder and each exercise performance test. It is concerning that children with low motor coordination report lower perceptions of ability even at a very young age.

Objectives: Self–other divergence refers to individuals judging themselves to be different from others. The authors investigated doping-related self-other divergence.Design: The authors used a quasi-experimental repeated-measures design to compare the effects of an independent variable (perspective: self, other) on doping likelihood and guilt. Method: Rugby players rated doping likelihood and guilt in situations describing two perspectives: self (their own behavior and feelings) and other (another player’s behavior and feelings). They also completed measures of moral agency, identity, perfectionism, and values (moral traits). Results: Doping likelihood was lower and guilt was higher for self-based ratings compared with other-based ratings. The self–other difference in doping likelihood was mediated by guilt and moderated by moral traits (larger for athletes with higher agency and values). Agency and values were more strongly related to self than other doping likelihood. Conclusions: Other-referenced measures differed from self-referenced measures of doping likelihood and guilt, indicating that it is wrong to presume equivalence of measurement.

Three experiments explore how sport consumers respond to sponsor advertisements featuring a team that lost a pivotal game. Drawing from social identity and appraisal theories, the authors hypothesize and find that high identifiers experience stronger negative emotions but less identity threat than low identifiers following their favorite team’s loss. When an advertisement features the losing team, low identifiers show less favorable evaluations toward the brand, whereas high identifiers report more favorable assessments. The results demonstrate that the tendency to hide and escape from the source of threat (losing team) among low identifiers is evidenced in processing marketing communications, whereas high identifiers display more positive evaluations toward the brand when the advertisement acknowledged the loss. The study findings provide implications for sponsors to consider different messaging strategies depending on the level of team identification with the losing team.
