运动行为领域中的调节匹配

调节匹配理论认为个体更倾向于采用与自身调节定向方式相匹配的行为策略, 并且当个体处于调节匹配状态时, 其行为表现会更好。通过梳理近年来运动领域关于调节匹配的研究发现, 调节匹配可以对运动行为的多个方面产生影响, 如促进运动员的运动表现、提高运动员的决策效能、增强体育锻炼参与度等。未来研究应注重对运动中调节匹配研究内容的扩充, 探讨调节匹配的内在机制, 并完善调节匹配的研究方法。     

Examining coach–athlete interactions using state space grids: An observational analysis in competitive youth sport

Objective

The purpose of this study was to compare the coach–athlete interaction structures of two competitive youth synchronized swimming teams differentiated on the basis of level of success.

Design

This comparison was a pilot test of the state space grid (SSG) observational methodology (Hollenstein, 2007) in sport settings.

Method

Two teams (two head coaches and 17 athletes in total) were observed over five training sessions. Coach and athlete behaviour was coded continuously for the duration of each training session. Measures of coach–athlete interaction were derived from these coded behaviours and compared between teams.

Results

Results revealed significant differences between the teams on measures of interaction variability, behavioural content patterns, and the sequencing of coach behaviours. The more successful team was characterized by less variable, more patterned interactions between coaches and athletes. The sequencing of coach behaviours for the more successful team emphasized the pairing of technical correction and positive reinforcement.

Conclusions

The findings suggest that positive environments characterized by a deliberate pattern of coach–athlete interaction may be associated with youth sport settings producing more satisfied and successful athletes. These results support the utility of SSGs for the analysis of interpersonal interactions in sport and highlight the unique insights made available through use of this methodology.     

In judo,Randori (free fight) and Kata (highly ritualized fight) differentially change plasma cortisol,testosterone, and interleukin levels in male participants

Two forms of competitive encounters namely Randori (free fight) and Kata (highly ritualized fight) were studied in 22 professional male judo fighters. The dyadic, symmetrical (in terms of body weight and fighting ability) encounters were videotaped to assess relationships between agonistic behavior and individual variations in plasma levels of testosterone (T), cortisol (C) and interleukins (IL‐6 and IL‐1β) measured before and after the competition. Unremarkably, winners showed longer attack but devoted less time to defensive behaviors when compared to losers. T increased only during Randori but the individual pre‐ and post‐competition T levels recorded in such fights were strongly correlated with the corresponding measures in the Kata for the same individuals. Interestingly, the pre‐ and post‐Randori competition T levels were higher in losers than in winners and T variations positively correlated with the frequencies of attacks and with the duration of defensive postures. The T response shows individual variation and seems to reflect evaluation of the likelihood of winning or losing. Both Randori and Kata induced a marked C increase, although the pre‐ and post‐Randori hormonal titers were higher than those found for the Kata. IL‐6 significantly increased between the pre‐ and the post‐Randori competition, but no such changes occurred during the Kata. No correlations were found between individual pre‐ and post‐competition C and IL‐6 and IL‐1β levels in either Randori or Kata. This suggests that C and cytokine release are unrelated to emotional or cognitive perception of the possible outcome of fighting but are a consequence of general motor activity. Martial arts appear to provide good human models to understand: (a) the relationships between conflict, hormones and the immune system and (b) the relationships between mood and physiological responses to competitive aggression.

Why won’t she sleep? Screen exposure and sleep patterns in young infants

The American Academy of Pediatrics recommends infants’ exposure to electronic screen-based media be minimized; however, more research is needed to understand effects of viewing screen-based media. Here, we examine relations between media use and sleep. Data were collected from mothers when their infants (N = 429) were four months of age. Mothers answered questions about the time their infants spent watching electronic screen-based media. Exposure to electronic screen-based media was negatively associated with nighttime sleep (but not daytime sleep), such that an hour of screen time was associated with nearly 13 min less sleep on a typical night.     

Bullying in youth sport training: A nationwide exploratory and descriptive research in Portugal

We describe and analyse the incidence and nature of bullying behaviours in male adolescent athletes (n = 1458), from 9 different sports, and 97 sport clubs, across Portugal. We collected information about the prevalence of roles in bullying, types of bullying, the frequency and duration of episodes, the location and activities in which they occur, the number of athletes involved, the feelings of those involved, communication of victims and bullies about their involvement in bullying episodes, the reasons ascribed, coping strategies and victim support sources. Altogether about 10% of athletes reported having been victimized, 11% participated in bullying episodes as bullies, and 35% as bystanders. Bullying episodes were usually characterized by low frequency and low duration and were most frequently verbal bullying inside the sport club. However, when episodes became repeated and with long duration,this tended to generalize to multiple types of bullying (especially verbal and social) and multiple places where episodes occurred, in sport clubs and also in competition. We conclude that bullying in youth sport training is an important topic; there is a need for both prevention and early broadly based intervention which involves coaches, peers and family.     

Enduring stress: A quantitative analysis on coping profiles and sport well-being in amateur endurance athletes

Endurance athletes experience physical and psychological stress during training and competition that can inhibit performance and promote negative health implications (i.e., lower well-being) without proper coping mechanisms (McCormick et al., 2018; Sakar & Fletcher, 2014). Additionally, these athletes that train at an amateur level have received limited attention regarding coping with stress and how it impacts well-being (McCormick et al., 2018). The purpose of this study was threefold: to (a) determine common coping profiles of trained amateur endurance athletes, (b) explore the relationship between sport well-being and these coping profiles, and (c) examine the potential roles that appraisals might play in the coping-well-being relationship. The results yielded five distinct coping profiles: Mixed Adaptive Copers (MAC), Mixed Maladaptive Copers (MMC), Engaged Copers (EC), Avoidant Copers (AC), and Social Copers (SC). Coping profiles differed across various variables including sport well-being, appraisals, and demographic factors. Overall, MAC and EC had higher levels of sport well-being. MAC viewed stressors as a challenge (i.e., opportunity) compared to EC and AC. These findings suggest the complex nature of coping in sport and that athletes should develop an assortment of coping strategies that provide different strategies for various stressful situations.     

Finger drawing by infant chimpanzees (<Emphasis Type="Italic">Pan troglodytes</Emphasis>)

We introduced a new technique to investigate the development of scribbling in very young infants. We tested three infant chimpanzees to compare the developmental processes of scribbling between humans and chimpanzees. While human infants start to scribble on paper at around the age of 18 months, our 13- to 23-month-old infant chimpanzees had never been observed scribbling prior to this study. We used a notebook computer with a touch-sensitive screen. This apparatus was able to record the location of the subjects touches on the screen. Each touch generated a fingertip-sized dot at the corresponding on-screen location. During spontaneous interactions with this apparatus, all three infants and two mother chimpanzees left scribbles with their fingers on the screen. The scribbles contained not only simple dots or short lines, but also curves and hook-like lines or loops, most of which were observed in the instrumental drawings of adult chimpanzees. The results suggest that perceptual-motor control for finger drawing develops in infant chimpanzees. Two of the infants performed their first scribble with a marker on paper at the age of 20–23 months. Just prior to this, they showed a rapid increase in combinatory manipulation of objects. These findings suggest that the development of combinatory manipulation of objects as well as that of perceptual-motor control may be necessary for the emergence of instrumental drawing on paper.     

Applying a relational lens to ethnographic inquiry: Storied insight into the inner workings of multicultural teams in men's elite football

ObjectiveTo examine the impact of transnational migration on the functioning of multicultural teams in men's elite football and to explore the cultural transition experiences of transnational players from the relational perspective of receiving football environments.Designand Method: This 26-month ethnographic study adopted a researcher-practitioner approach to investigate two elite European football clubs during the course of two complete seasons. Over 80 male participants from 18 different countries were involved in the approximately 1200 h of field observation (e.g., practices, games, closed-door meetings, etc.) and 50 h of transcribed interviews. Detailed field notes and interview data were thematically analyzed, followed by a narrative analysis of structure and form. Finally, the genre of ethnographic creative non-fiction was employed to present the findings.FindingsBy applying a relational lens to the study of cultural transitions, this investigation illuminates the centrality of relations in the daily functioning of multicultural teams embedded in transnational networks and spaces. The complex interactional dynamic between transnational players and members of the receiving environment as well as the structural constraints shaping footballing (sub)cultures and behaviours highlight the salience of restrained agency as a collective phenomenon in elite men's football. Moreover, the study explores the hows of cultural transition by engaging with temporality and proposing a complementary perspective that extends current understandings in the narration of cultural transition experiences.ConclusionsThe findings carry applied utility that can benefit stakeholders and practitioners working with culturally diverse teams in the deployment of culturally informed club management strategy, educational tools, and interventions.     

Follow the leader: Identity leadership and moral behaviour in social situations among youth sport teammates

ObjectivesAlthough social identity has been linked to moral behaviour in past research, we know less about how the identity-enhancing behaviours of athlete leaders may relate to the experience of prosocial and antisocial behaviour between youth sport teammates. This study examined the relations between perceptions of athlete identity leadership and moral behaviour in social situations outside of training and competition.MethodsParticipants were 130 competitive male and female youth ice hockey players (M_age = 13.45 years, SD = 1.82, range = 10–17) from nine teams in a Northeastern Ontario city in Canada. Measures of identity leadership and moral behaviour were completed concurrently within the final three weeks of the regular season.ResultsUsing structural equation modeling, results demonstrated a significant positive association between identity leadership and both engaging in prosocial behaviour toward teammates (β = .37, p = .003) and receiving prosocial behaviour from teammates (β = 0.40, p < .006), accounting for 34% and 51% of the variance in each prosocial outcome, respectively. Although the relations with antisocial behaviour (engaged and received) were in the expected negative direction, the path estimates were not significant (ps > .23).ConclusionThese findings further our understanding of identity leadership in youth sport generally, offering insight into the relations between identity-enhancing athlete leader behaviours and moral behaviour. The findings also extend past moral behaviour research to consider the social situations in which teammates find themselves outside of training and competition.
