Getting a grip on the resilience to blur: The impact of simulated vision loss on a visually guided combat sports interaction

Research has shown that performance in highly visually demanding sports can be resilient to substantial levels of blur. This raises the question whether the need for high visual clarity might be reduced even more in less visually demanding sports such as combat sports, where athletes compete at relatively close distances. The aim of this study was to examine the resilience to blur in the grip fighting phase of judo as an exemplar of a visually guided combat sports task. The results were particularly relevant for the purposes of Paralympic judo for athletes with vision impairment (VI judo), because athletes are currently allowed to compete with a visual acuity (VA) of 1.0 logMAR or worse (i.e., 6/60 or 20/200 vision), suggesting this is the presumed level of impairment that decreases performance in able-sighted judo. We let 28 able-sighted judo athletes compete in pairs in a series of grip fighting tasks under increasing levels of simulated vision impairment. Visual function was tested in each condition by measuring VA and contrast sensitivity (CS). We found that VA was a better predictor than CS of grip fighting performance. VA needed to be reduced to at least 1.3 logMAR before a decrease in performance was found, with approximately twice as much blur needed to be applied when compared to visually demanding tasks such as cricket batting, but less than what has been found in static tasks such as basketball free-throw shooting and golf putting. These findings hold implications for VI judo regulations, suggesting that a more severe degree of impairment should be required to participate than is currently the case.     

Individual differences in performance and learning of visual anticipation in expert field hockey goalkeepers

The study of anticipation in truly expert performers can provide insight into how they cope with extreme time constraints. The purpose of this dual-experiment paper was to investigate individual differences; in anticipation of the penalty corner drag-flick, its trainability, and transfer of improvement to field settings. Australian international and national male field-hockey goalkeepers participated. In experiment 1, international and national goalkeepers (n = 11) completed a penalty corner drag-flick temporal occlusion task that presented; defensive runner positioning at the penalty spot, drag-flicker kinematics, and ball flight. Results indicated seven goalkeepers integrated runner contextual and drag-flicker kinematic information to anticipate above chance. The cause of individual differences was independent pick-up of run and kinematic cues that presented greater opportunity to integrate sources for anticipation. In experiment 2, a sub-sample of goalkeepers participated and received temporal occlusion training or no training. Results indicated individualized improvement in anticipation across video, field, and competition assessments for those that received the intervention, but not controls. Improvements on video test were retained for six months. An individual differences approach can identify deficiencies in anticipation, which can be improved through perceptual training that transfers to motor responses. This contributes to theoretical and practical knowledge to develop anticipation skill.     

Autonomy support and control within mother-father parenting structures: A person-centered approach in youth sport

In the youth sport context, parents play an important role in the motivation of adolescent athletes. From a self-determination theory viewpoint, the provision of autonomy support versus control by parents is an essential part of this socialization process. The purpose of the present study was threefold: (a) identify distinct mother-father parenting profiles of autonomy support and control based on perceptions of adolescent athletes, (b) examine the unique influence of mother-father parenting profiles on adolescent athletes' motivational responses (i.e., parent-to-child effects), and (c) understand the contribution of adolescent athletes' motivation to the emergence of these mother-father parenting profiles (i.e., child-to-parent effects). To test our hypotheses, a person-centered approach (latent profile analysis) was employed to analyze data collected from a sample of high school athletes (N = 264; Mage = 15.7 years, 64% female). Results provided evidence supporting a four-profile solution: Strong Autonomy Support Dominant: Both Parents (n = 26, 9.8%), Weak Control Dominant: Both Parents (n = 111, 42.0%), Moderate Autonomy Support and Control: Both Parents (n = 21, 8.0%), and Weak Autonomy Support Dominant: Both Parents (n = 106, 40.2%). The four mother-father parenting profiles were found to be differentially predicted by, and predictive of, adolescent athletes' adaptive and maladaptive motivational responses (i.e., basic psychological needs satisfaction, autonomous and controlled motivation). This study illuminated a general pattern of congruency in the provision of autonomy support and control by parents within mother-father parenting structures and contributed empirical evidence pointing to the reciprocal nature of interpersonal processes in parent-athlete relationships.     

A longitudinal examination of thriving in sport performers

To sustain success in sport, athletes need to function effectively in their competitive encounters and maintain this level over repeated events. Yet, to date, little is known about how athletes can continue to fully function (i.e., thrive) in their sporting encounters. Equally, there is a lack of research in relation to the factors that predict thriving. Testing the premise that basic psychological needs (i.e., for autonomy, competence, and relatedness) predict optimal functioning, the aim of this study was to provide the first longitudinal examination of thriving in sport. Sport performers (N = 268) completed questionnaires assessing thriving and basic psychological need satisfaction on three occasions across 28 days. Longitudinal structural equation modeling showed thriving to be highly predicted by both the experience of recent thriving and the perceived satisfaction of basic psychological needs. These findings highlight an important mechanism through which coaches and practitioners can initiate and maintain thriving in the athletes that they work with across a series of sporting encounters.     

Mental Transformation Skill in Young Children: The Role of Concrete and Abstract Motor Training

We examined the effects of three different training conditions, all of which involve the motor system, on kindergarteners’ mental transformation skill. We focused on three main questions. First, we asked whether training that involves making a motor movement that is relevant to the mental transformation—either concretely through action (action training) or more abstractly through gestural movements that represent the action (move‐gesture training)—resulted in greater gains than training using motor movements irrelevant to the mental transformation (point‐gesture training). We tested children prior to training, immediately after training (posttest), and 1 week after training (retest), and we found greater improvement in mental transformation skill in both the action and move‐gesture training conditions than in the point‐gesture condition, at both posttest and retest. Second, we asked whether the total gain made by retest differed depending on the abstractness of the movement‐relevant training (action vs. move‐gesture), and we found that it did not. Finally, we asked whether the time course of improvement differed for the two movement‐relevant conditions, and we found that it did—gains in the action condition were realized immediately at posttest, with no further gains at retest; gains in the move‐gesture condition were realized throughout, with comparable gains from pretest‐to‐posttest and from posttest‐to‐retest. Training that involves movement, whether concrete or abstract, can thus benefit children's mental transformation skill. However, the benefits unfold differently over time—the benefits of concrete training unfold immediately after training (online learning); the benefits of more abstract training unfold in equal steps immediately after training (online learning) and during the intervening week with no additional training (offline learning). These findings have implications for the kinds of instruction that can best support spatial learning.     

Road safety education for older drivers: Evaluation of a classroom-based training initiative

Around the world, a growing proportion of drivers are aged 70 or over. Although accident rates for older drivers are lower than for young or novice drivers, increased frailty and slowed reactions mean that older drivers are at higher risk of death or serious injury when involved in a road collision. The objectives of this study were to: (a) identify driving knowledge and self-regulatory strategies among a group of older drivers with a view to planning future on-road training; (b) measure driver self-assessments of ability and confidence before and after classroom training delivered by driving instructors; (c) evaluate the utility and acceptability of training courses for older drivers using questionnaires and focus groups; d) examine the characteristics of course participants.142 drivers aged ≥75 completed a two-hour classroom-based driving course and took part in the evaluation: 94 aged 75–79, 48 aged ≥80, 68% male. Main reasons for taking part were to update knowledge, improve driving and check they were safe to drive. Results showed that females were more likely than males to avoid driving in difficult conditions (at night, in bad weather, unfamiliar roads). More drivers aged 75–79 said they did not restrict their driving (52, 57%) compared to drivers aged ≥80 (19, 43%). Pre-course, males rated their driving confidence and ability significantly higher than females. Post-course, self-ratings of confidence and ability were unchanged for 76 (60%) drivers. However, two-thirds reported improved knowledge and 80% said they would change their driving behaviour as a result of the course. Focus group results suggest that competent drivers are more likely to attend educational courses than unsafe drivers. This study provides preliminary evidence that classroom-based training can initiate behaviour change among older drivers. Future research will examine the effectiveness of on-road training in this age group.     

The question of the training analysis system. Notes from the debate in Oslo

The Norwegian discussion of the training analyst system and the pro et contra arguments are shortly presented. When this note is written, the Board is contemplating to propose a revision of the by-laws, making it somewhat easier to fulfil the criteria for being approved as training analyst.     

The relations between specific measures of simulated driving ability and functional ability: New insights for assessment and training programs of older drivers

To gain new insights for driving assessment and training, this study had two objectives: (1) to investigate the relations between specific measures of older drivers’ driving ability and demographic/functional ability measures, and (2) to verify the explained variance of these relations to determine the strength of these relations. A sample of 55 older drivers (mean age 76 years) completed a set of functional ability tests as well as a driving simulator test. Results indicate that (1) each specific driving measure is related to a specific set of functional abilities, and (2) only a small proportion of the variability observed in the specific driving measures is explained by demographic variables (3–15%) and by functional abilities (7–36%). For driving assessment programs, it will be necessary to assess several functional abilities to cover the complexity of the driving task. Furthermore, an assessment program focusing solely on demographic and/or functional ability measures, will not be successful in discriminating safe from unsafe older drivers. For driving training programs, it will be necessary to focus on the right set of functional abilities given that specific driving measures are related to different functional abilities. Moreover, a training targeting functional abilities might only have marginal effects on driving ability, given the relatively low amount of driving ability variance that is explained by functional abilities.     

Perfectionism,burnout and engagement in youth sport: The mediating role of basic psychological needs

Recent research indicates perfectionistic concerns and perfectionistic strivings share divergent associations with athlete burnout and athlete engagement. Guided by self-determination theory, the present study examined whether these associations were explained by basic psychological needs. Youth athletes (n = 222, M age = 16.01, SD = 2.68) completed measures of multidimensional perfectionism, athlete burnout, athlete engagement, basic psychological need satisfaction and thwarting. Structural equation modelling revealed that basic psychological need satisfaction and thwarting mediated the perfectionism–engagement and perfectionism–burnout relationships. Perfectionistic concerns shared a negative relationship (via need satisfaction) with athlete engagement and a positive relationship (via need satisfaction and thwarting) with athlete burnout. In contrast, perfectionistic strivings shared a positive relationship (via need satisfaction) with athlete engagement and a negative relationship (via need satisfaction and thwarting) with athlete burnout. The findings highlight the role of basic psychological needs in explaining the differential associations that perfectionistic concerns and strivings share with athlete burnout and engagement.
