A 6-month self-efficacy intervention was compared with attention-control intervention on physical activity, clinical outcomes, and mediators immediate postintervention and 6-month postintervention in 182 older adults with knee osteoarthritis and hypertension using a randomized controlled trial design. The intervention group received six weekly individual physical therapy sessions for lower-extremity exercise and fitness walking and nine biweekly nurse telephone counseling sessions. The attention-control group received six weekly and nine biweekly nurse telephone sessions on health topics. Lower-extremity exercise was assessed by e-diary; fitness walking was assessed by accelerometer and e-diary; blood pressure was assessed by automated monitor; function was assessed by performance-based tests and questionnaires; and pain, self-efficacy, and outcome expectancy were assessed by questionnaires. Self-reported lower-extremity exercise and fitness walking, function, pain, self-efficacy, and outcome expectancy showed significant group or group by time effects favoring intervention. The intervention did not improve physical activity by accelerometer and blood pressure. Mean minutes of fitness walking fell short of the 150 min/week goal.

Background: To determine Australian primary school principals’, teachers’, and parents’ attitudes to changing school uniform policies to allow students to wear sports uniforms every day and to assess associations between participant characteristics and their attitudes. A secondary aim was to identify principals’ and teachers’ perceived barriers to uniform changes. Methods: Cross-sectional surveys of principals, teachers, and parents of children in grades 2 to 3 (age 7–10 y) from 62 Australian primary schools (Oct 2017–Mar 2018) were undertaken. Mixed logistic regression analyses assessed the associations between participant characteristics and attitudes toward uniform changes. Results: In total, 73% of the principals (38/52) who responded reported that their school only allowed children to wear a sports uniform on sports days. Overall, 38% of the principals (18/47), 63% of the teachers (334/579), and 78% of the parents (965/1231) reported they would support a policy that allowed children to wear daily sports uniforms. The most commonly reported barrier was the perception that sports uniforms were not appropriate for formal occasions. Conclusions: Although the majority of the principals were not supportive of a change to a daily sports uniform, the majority of the teachers and parents were. Strategies to improve principal support may be required if broader adoption of physical activity–supporting uniforms is to be achieved.

Mental toughness is a factor related to performance, better coping, and increased confidence. There has been a growing trend toward assessing mental toughness behaviorally. The purpose of this paper was to develop a behavioral assessment of mental toughness in volleyball. Following a five-stage process to develop a systematic observation instrument, the current study identified 10 mental toughness behaviors in volleyball, specifically, six behaviors occurring during a play and four behaviors after a play (i.e., when a point is scored from the opposing team). Furthermore, eight behaviors represent mentally tough actions, while two behaviors represent mentally weak actions. The results indicate that the behavioral checklist is a reliable systematic observation instrument. Coaches and certified mental performance consultants can benefit from using this checklist by discussing mental toughness and behaviors corresponding to mental toughness during game play, and then have a quantifiable way to track behaviors with individuals and volleyball teams.

Injuries are commonplace in high-intensity sport, and research has explored how athletes are psychologically affected by such events. As injuries carry implications for the group environment in sport teams, the authors explored what occurs within a team during a time period of injury from a coach perspective and how high-performance coaches manage a group at this time. Semistructured interviews were conducted with 10 Canadian university basketball head coaches. Thematic analysis revealed four high-order themes in relation to how coaches managed group dynamics from the moment of the injury event to an athlete’s reintegration into the lineup. Strategies to mitigate the negative effects of injury on the group environment while prioritizing athlete well-being involved remaining stoic at the time of an injury event, maintaining the injured athlete’s sense of connection to the team, and coordinating with support staff throughout the recovery and reintegration process.

Background: The ParticipACTION Report Card on Physical Activity for Adults is a knowledge exchange tool representing a synthesis of the literature and data available at the national level. The purpose of this paper is to summarize the results of the inaugural 2019 edition. Methods: Thirteen physical activity indicators, grouped into 4 categories, were graded by a committee of experts using a process that was informed by the best available evidence. Sources included national surveys, peer-reviewed literature, and gray literature such as government and nongovernment reports and online content. Results: Grades were assigned to Daily Behaviors (overall physical activity: D; daily movement: C; moderate to vigorous physical activity: F; muscle and bone strength: INC; balance: INC; sedentary behavior: INC; sleep: B−), Individual Characteristics (intentions: B+), Settings and Sources of Influence (social support: INC; workplace: INC; community and environment: B−; health and primary care settings: C−), and Strategies and Investments (government: B−). Conclusions: Generally, lower grades were given to behavior-related indicators (eg, overall physical activity) and better grades for indicators related to investments, community supports, and strategies and policies. Research gaps and future recommendations and directions are identified for each indicator to support future practice, policy, and research directions.

Context: Current tools for sideline assessment of balance following a concussion may not be sufficiently sensitive to identify impairments, which may place athletes at risk for future injury. Quantitative field-expedient balance assessments are becoming increasingly accessible in sports medicine and may improve sensitivity to enable clinicians to more readily detect these subtle deficits. Objective: To determine the validity of the postural sway assessment on the Biodex BioSway™ compared with the gold standard NeuroCom Smart Equitest System. Design: Cross-sectional cohort study. Setting: Clinical research laboratory. Participants: Forty-nine healthy adults (29 females: 24.34 [2.45] y, height 163.65 [7.57] cm, mass 63.64 [7.94] kg; 20 males: 26.00 [3.70] y, height 180.11 [7.16] cm, mass 82.97 [12.78] kg). Intervention(s): The participants completed the modified clinical test of sensory interaction in balance on the Biodex BioSway™ with 2 additional conditions (head shake and firm surface; head shake and foam surface) and the Sensory Organization Test and Head Shake Sensory Organization Test on the NeuroCom Smart Equitest. Main Outcome Measures: Interclass correlation coefficient and Bland–Altman limits of agreement for Sway Index, equilibrium ratio, and area of 95% confidence ellipse. Results: Fair–good reliability (interclass correlation coefficient = .48–.65) was demonstrated for the stance conditions with eyes open on a firm surface. The Head Shake Sensory Interaction and Balance Test condition on a firm surface resulted in fair reliability (interclass correlation coefficient = .50–.59). The authors observed large ranges for limits of agreement across outcome measures, indicating that the systems should not be used interchangeably. Conclusions: The authors observed fair reliability between BioSway™ and NeuroCom, with better agreement between systems with the assessment of postural sway on firm/static surfaces. However, the agreement of these systems may improve by incorporating methods that mitigate the floor effect in an athletic population (eg, including a head shake condition). BioSway™ may provide a surrogate field-expedient measurement tool.

Purpose: To investigate whether youth and adults can perceive differences in exertion between walking and running at speeds near the preferred transition speed (PTS) and if there are age-related differences in these perceptions. Methods: A total of 49 youth (10–12 y, n = 21; 13–14 y, n = 10; 15–17 y, n = 18) and 13 adults (19–29 y) completed a walk-to-run transition protocol to determine PTS and peak oxygen uptake. The participants walked and ran on a treadmill at 5 speeds (PTS–0.28 m·s−1, PTS–0.14 m·s−1, PTS, PTS+0.14 m·s−1, PTS+0.28 m·s−1) and rated perceived exertion using the OMNI Perceived Exertion (OMNI-RPE) scale. Oxygen consumption was measured during the walk-to-run transition protocol to obtain the relative intensity (percentage of peak oxygen uptake) at PTS. OMNI-RPE scores at all speeds and percentage of peak oxygen uptake at PTS were compared between age groups. Results: The 10- to 12-year-olds transitioned at a higher percentage of peak oxygen uptake than adults (64.54 [10.18] vs 52.22 [11.40], respectively; P = .035). The 10- to 14-year-olds generally reported higher OMNI-RPE scores than the 15- to 17-year-olds and adults (P < .050). In addition, the 10- to 14-year-olds failed to distinguish differences in OMNI-RPE between walking and running at PTS and PTS+0.14 m·s−1. Conclusions: Children aged 10–14 years are less able to distinguish whether walking or running requires less effort at speeds near the PTS compared with adults. The inability to judge which gait mode is less demanding could hinder the ability to minimize locomotive demands.

This study sought to examine coaches’ perceptions of social identity among their athletes and explore the ways that they may attempt to influence its development. Semistructured interviews were conducted with 12 head coaches (M age = 49.25 years; SD = 6.5 years; M experience  = 15.75 years; SD = 7.66 years; n female = 1) of male (n = 8) and female (n = 4) competitive youth ice hockey teams. Three main themes were identified through our analysis. First, the coaches’ perceptions of athletes’ social identities were described through examples of peer connection and similarity (i.e., in-group ties), athletes’ experience of positive affect (i.e., in-group affect), and athletes demonstrating the meaning and value that they attribute to team membership (i.e., cognitive centrality). Second, the coaches discussed a variety of ways that they sought to develop and reinforce a shared social identity within their teams. These behaviors aligned with principles advanced within the social identity leadership literature—namely, the coaches acted as in-group prototypes, in-group champions, entrepreneurs of identity, and embedders of identity. Finally, the coaches identified parents and cliques as key social agents with the ability to undermine social identity development. The findings are discussed in relation to both their theoretical and practical implications.

The current study presents a systematic review of six empirical research studies that have explored coping amongst elite-level sport coaches. The study was carried out employing Fletcher et al.’s meta-model of stress, emotions, and performance as a basis for the review. The present results clearly revealed that, despite being an important aspect of coaches’ functioning, coping is almost never researched in its full complexity, and scarce attention is given to cognitive appraisals and long-term outcomes. To our knowledge, current research has so far been limited to the perceived stressors and employed coping strategies. Compared with problem-focused coping, emotion-focused coping is less frequently reported. Emotion-focused coping also has some limitations regarding occurrence and diversity in reported strategies. The reasons for this are not well-known due to the lack of comprehensiveness in the research. Hence, researchers are encouraged to further investigate coping amongst elite-level coaches and to do so by treating it as a concept affected by appraisals and personal and situational characteristics that exist in the context of a larger stress process.
