The purpose of this study was to examine the effects of different success criteria on motor learning in children. Forty-eight children threw soft-golf balls toward a circular target using their nondominant arm. On Day 1, they performed six blocks of 12 trials from 5.5 m. On Day 3, they performed a 12-trial retention test followed by a 12-trial transfer test. Participants were randomly assigned to one of four groups: difficult criteria for success, relatively easy criteria for success (RES), easy criteria for success, and control. Results demonstrated that there was a significant difference between the RES and control groups in their throwing accuracy on the retention and transfer tests, and the RES group had the highest score compared with the other two groups. This research suggests that providing relatively easy criteria facilitates motor skill acquisition in children.

Physical activity (PA) guidelines are informed by epidemiological evidence but do not account for people's motivation for exerting physical effort. Previous research has shown that people are less motivated to engage in moderate- to vigorous-intensity PA when fatigued. In a two-study series, we investigated how intensity and duration affected people's willingness to engage in PA using an effort-discounting paradigm. A secondary purpose was to examine whether effort discounting was affected by mental fatigue. Both studies revealed a significant Intensity × Duration interaction demonstrating a reduced willingness to engage in PA of higher intensities across increasing duration levels. Study 1 demonstrated greater effort discounting for vigorous-intensity PA with increasing mental fatigue; however, this effect was not observed in Study 2. Findings provide novel insight toward people's motivation for engaging in PA based on the properties of the task, and some evidence suggesting feelings of fatigue may also influence motivation to exert physical effort.

Physical fitness self-concept (PFSC) is an important predictor of motivation and physical activity in children. Recent studies revealed that not only PFSC but also its interplay with perceptions of one's ideal and ought physical fitness self are related to motivation and physical activity. As the meaning of ideal and ought selves in children is yet unclear, this study aimed to investigate how PFSC, ideal physical fitness self, and ought physical fitness self are related to children's motivation and physical activity. Six hundred forty-five children (Mage = 8.87 years) filled out questionnaires twice with an interval of approximately 8 months. Polynomial regression with response surface analyses and mediation analyses was conducted. Results showed that PFSC, rather than ideal and ought self-perceptions, is associated with autonomous motivation, self-efficacy, and physical activity. The relationship between PFSC and physical activity was mediated by self-efficacy. Findings indicate that physical activity promotion programs should include PFSC and self-efficacy enhancement in childhood.

While widely acknowledged as being important for team-sport performance, the contribution of peripheral vision is poorly understood. This study aimed to better understand the role of far peripheral vision in team sport by exploring how domain experts and novices used far peripheral vision to support decision making and action control. Expert (n = 25) and novice (n = 23) Australian football players completed a perception-only task to assess the extent of their peripheral field. Next, they completed two sport-specific variations (response and recognition) of a "no-look" pass task that required passing a ball to a teammate who appeared in their far peripheral field. In the perception-only task, novices outperformed experts. However, in the sport-specific action response and recognition tasks, experts demonstrated superior performance as they responded to the stimulus farther from central vision and more accurately. Results demonstrate expertise effects for the use of far peripheral vision in sport.

Self-report and neural data were examined in 14 right-handed college-age males screened from a pool of 200 to verify neural activity during imagery and that the neural activity (area of brain) varies as a function of the imagery type. Functional magnetic resonance imaging data collected during real-time imagery of the three Movement Imagery Questionnaire-3 abilities indicated frontal areas, motor areas, and cerebellum active during kinesthetic imagery, motor areas, and superior parietal lobule during internal visual imagery, and parietal lobule and occipital cortex during external visual imagery. Central and imagery-specific neural patterns were found providing further biological validation of kinesthetic, internal visual, and external visual complementing results on females. Next, research should (a) compare neural activity between male participants screened by self-reported imagery abilities to determine if good imagers have more efficient neural networks than poor imagers and (b) determine if there is a statistical link between participants' neural activity during imagery and self-report Movement Imagery Questionnaire-3 scores.

We examined skill-based differences in the detection and utilization of contextual information over a period of increasing exposure to an opponent's action preferences in soccer. Moreover, we investigated the ability of athletes to adapt to changes in these action preferences over time. In an initial detection phase, the attacking opponent demonstrated a proclivity to either pass or dribble, with these preferences being reversed in a subsequent adaptation phase of the same length. Skilled soccer players showed superior anticipation accuracy across both phases compared with less-skilled counterparts. The skilled participants significantly enhanced their performance over both phases, despite a significant drop in performance immediately following the change in opponent action preferences. In contrast, the less-skilled group only improved over the detection phase. Gaze data revealed that the skilled participants fixated more on kinematically relevant areas, compared with the less-skilled group, and increased the time spent fixating the player "off the ball" following greater volumes of exposure. Our novel findings elaborate on how skilled performers use both action preferences and motion information to anticipate an opponent's impending actions in sport.

MAN v FAT Soccer is a sport-based weight-loss program for overweight and obese men that originated in the United Kingdom (i.e., as MAN v FAT Football) and appears to successfully engage men with weight loss. We sought to explore whether the program would work in an Australian context by (a) establishing a foundation for the implementation of the program on a larger scale and (b) determining how large-scale implementation is most feasible. We conducted a nonrandomized, single intervention group feasibility trial of MAN v FAT Soccer in Australia with 418 male participants with a body mass index greater than 27.50 kg/m2. Results indicate that the program is acceptable, with participants reporting positive perceptions of the various components of the program and a high proportion reporting intentions to recommend the program to others (95.9%). Furthermore, preliminary effectiveness results indicate positive changes in weight (4.6% reduction) and physical activity (88.5% increase) and improvements in psychological outcomes such as depression (17.6% decrease), stress (19.0% decrease), and body appreciation (19.1% increase). Our findings provide general support for the feasibility of MAN v FAT Soccer and the notion that leveraging competition and masculinity may help drive men's health behavior change.

The purpose of this study was to develop and test models of scanning activity in football. Gibson's ecological approach of visual perception and exploratory activity provided the theoretical framework for the models. The video-based data analysis consisted of 17 selected matches and 239 players of the Union of European Football Associations (UEFA) U17 and U19 European Championship 2018 and the UEFA U17 and U21 European Championship 2019. The results showed a positive relation between scanning frequency and successful passes, as well as changes in body orientation. Scanning frequency was also related to a player's appearances in national teams and to opponent pressure. Opponent pressure had a large effect on pass result and the player's body orientation. Previous research on the relation between scanning frequency and performance was extended by several contextual predictors. Future research should focus on gaining a deeper understanding of the relation between scanning frequency and further contextual variables related to scanning.

Physical declines with aging may negatively impact women's body image. Group physical activity can be a source of social support that may improve body image. We examined how social support experienced in group physical activity programs impacts older women's body image. Guided by interpretive description, we interviewed 14 women age 65 years and older who participated in group physical activity classes. Although women experienced both positive and negative body image, body image was generally positively impacted by physical activity. Four themes described social support processes that affected body image in the physical activity context: fitting in and being inspired through identifying with others; what is discussed and not discussed; providing comfort, understanding, and acceptance; and skilled and empathetic interactions with instructors. Understanding how social support in group physical activity can promote positive body image throughout aging can inform practical guidelines for facilitating and improving support in this context.
