Intermittent claudication is debilitating leg pain affecting older people with peripheral arterial disease, which is improved by regular walking. This study evaluated associations between psychosocial variables and 6-min walk distance (6MWD) to identify factors that motivate walking. A total of 142 individuals with intermittent claudication (116 males; M age = 66.9 years [SD = 10.2]) completed cross-sectional assessments of sociodemographics, walking treatment beliefs and intention (Theory of Planned Behaviour), illness perceptions (Revised Illness Perceptions Questionnaire), and 6MWD. Multiple linear regression was used to evaluate relationships among psychosocial variables (treatment beliefs and illness perceptions) and outcomes (walking intention and 6MWD). Theory of planned behavior constructs were associated with intention (R = .72, p < .001) and 6MWD (R = .08, p < .001). Illness perceptions were associated with 6MWD only (R = .27, p < .001). Intention (β = 0.26), treatment control (β = −0.27), personal control (β = 0.32), coherence (β = 0.18), and risk factor attributions (β = 0.22; all ps < .05) were independently associated with 6MWD. Treatment beliefs and illness perceptions associated with intention and 6MWD in people with intermittent claudication are potential intervention targets.

Introduction: Adequate gross motor coordination is essential for children participating in age-related physical activities and has an important role in maintaining sufficient physical activity levels during the life course. Aim: To examine the association between moderate-to-vigorous physical activity (MVPA) and gross motor coordination during sedentary behavior in early childhood (ages 3–6 y). Methods: The sample comprised 209 children aged 3–6 y. Gross motor coordination was assessed according to the Movement Assessment Battery for Children (MABC-2). The battery to assess gross motor coordination comprised the aiming and catching, and balance components. MVPA was measured by accelerometry worn for 7 consecutive days (Monday to Sunday). Results: Our data indicated that 31.5% of the sample had low, 32.5% medium, and 36.0% high gross motor coordination. Multiple linear regression analysis showed that MVPA was positively associated with gross motor coordination, adjusted for gender and sedentary behavior. Conclusions: Preschoolers with high gross motor coordination spend more time in MVPA. Gross motor coordination development should therefore be a key strategy in childhood interventions aiming to promote physical activity.

Background: This study assessed the independent associations between participation in self-reported sport and exercise activities and incident cardiovascular disease (CVD). Methods: Data were from 13,204 participants in the Atherosclerosis Risk in Communities Study cohort (1987–2015). Baseline sport and exercise activities were assessed via the modified Baecke questionnaire. Incident CVD included coronary heart disease, heart failure, or stroke. Multivariable-adjusted Cox proportional hazard models assessed the association of participation in specific sport and exercise activities at enrollment with risk of CVD. Results: During a median follow-up time of 25.2 years, 30% of the analytic sample (n = 3966) was diagnosed with incident CVD. In fully adjusted models, participation in racquet sports (hazard ratio [HR] 0.75; 95% confidence interval [CI], 0.61–0.93), aerobics (HR 0.75; 95% CI, 0.63–0.88), running (HR 0.68; 95% CI, 0.54–0.85), and walking (HR 0.89; 95% CI, 0.83–0.95) was significantly associated with a lower risk of CVD. There were no significant associations for bicycling, softball/baseball, gymnastics, swimming, basketball, calisthenics exercises, golfing with cart, golfing with walking, bowling, or weight training. Conclusions: Participation in specific sport and exercises may substantially reduce the risk for CVD.

To examine associations between perceived destination accessibility within different distances from home and self-reported overall amounts of walking for different purposes among older adults (aged ≥ 65 years) in Brisbane, Australia (N = 793) and Hong Kong, China (N = 484). Perceived neighborhood destination accessibility types were derived from latent class analysis using comparable measures of perceived distance to 12 destinations from epidemiological studies in the two cities. Associations of perceived destination accessibility with measures of within-neighborhood walking were also estimated in Hong Kong participants. Better perceived destination accessibility was positively associated with the likelihood of walking in Brisbane participants only. Perceived destination accessibility within a short distance from home (5-min walk) was negatively related to the amount of within-neighborhood walking for transport in Hong Kong residents who walked. Our findings suggest that providing moderate-to-high, but not extreme, levels of destination accessibility may be optimal for the promotion of walking in older community dwellers.

This study investigated the contact forces and muscle activation during 2 choreographed fall techniques in contemporary dancers and how these were affected by the fall technique. Ten collegiate-level dancers were instructed in 2 choreographed falls: (1) an anteriorly focused fall involving ankle plantar flexion, knee flexion, and hip flexion with dispersion of forces up the anterior surface of the shank (technique 1) and (2) a laterally focused fall involving inversion at the ankle with dispersion of forces up the lateral aspect of the shank (technique 2). The knee and hip contact forces were 26.3% smaller (technique 1: 1743 N vs technique 2: 1284 N) and 24.1% greater (technique 1: 1334 N vs technique 2: 1656 N), respectively, in technique 2 (P < .03). At the time of knee contact, percentage of maximal voluntary isometric contraction (%MVIC) was 45.8% greater for rectus femoris muscle (technique 1: 7.2% vs technique 2: 10.5%) and 96.9% greater for gluteus medius muscle (technique 1: 3.2% vs technique 2: 6.3%) (P < .01) in technique 2. The results provide insight into determining safer landing strategies to avoid knee injuries in individuals who experience a fall (ie, dancers, athletes, and older adults).

The aim of the study was to establish whether there were differences in speed–accuracy movement learning strategies between children, young adults, and older adults. A total of 30 boys, 30 young adult men, and 30 older men were seated in a special chair at a table with a Dynamic Parameter Analyzer 1. Participants had to perform a speed–accuracy task with the right-dominant hand. It may be assumed that the motor variables of children are more prone to change during the fast learning process than those of young adults and older adults and that the development of internal models is more changeable in children than in young adults and the older adults during the fast adaptation-based learning process.

Sport participants continually seek methods to hone their skills and achieve expert performance. One means to achieve this is through the use of observational learning (OL). The Functions of Observational Learning Questionnaire (FOLQ) was created to measure the types of OL athletes used. The data presented herein builds from prior research in which the use of the FOLQ was extended to coaches and officials. The researchers included the following open-ended question: “Do you observe others/self for anything not addressed above?” Responses to this question, however, have yet to be reported. As such, the purpose of this study was to analyze participants’ responses to understand how coaches and officials use observational learning. Many identified codes encompassed ideas already included within the FOLQ; however, new coding categories emerged. Specifically, coaches reported using observational learning for Self-Reflection, officials reported using observational learning for Self-Presentation, and both groups reported using observational learning to improve Communication. These results demonstrate the importance of OL to coaches’ and officials’ development. Further, the results highlight that the FOLQ might overlook coaches’ and officials’ uses of OL. Regardless, the various uses of OL ought to be included in coaching and officiating education programs to foster elite performance.

Purpose: The session rating of perceived exertion (sRPE) is a well-accepted method of monitoring training load in athletes in many different sports. It is based on the category-ratio (0–10) RPE scale (BORG-CR10) developed by Borg. There is no evidence how substitution of the Borg 6–20 RPE scale (BORG-RPE) might influence the sRPE in athletes. Methods: Systematically training, recreational-level athletes from a number of sport disciplines performed 6 randomly ordered, 30-min interval-training sessions, at intensities based on peak power output (PPO) and designed to be easy (50% PPO), moderate (75% PPO), or hard (85% PPO). Ratings of sRPE were obtained 30 min postexercise using either the BORG-CR10 or BORG-RPE and compared for matched exercise conditions. Results: The average percentage of heart-rate reserve was well correlated with sRPE from both BORG-CR10 (r = .76) and BORG-RPE (r = .69). The sRPE ratings from BORG-CR10 and BORG-RPE were very strongly correlated (r = .90) at matched times. Conclusions: Although producing different absolute numbers, sRPE derived from either the BORG-CR10 or BORG-RPE provides essentially interchangeable estimates of perceived exercise training intensity.

Empirical findings consistently suggest that an external focus of attention leads to superior performance when compared to an internal focus by encouraging more automatic processing. However, for certain skills (e.g., gymnastics routines) it can be challenging to identify a meaningful external focus cue. A related line of research suggests that focusing on the general feeling of a movement (i.e., holistic focus) may also be useful in avoiding conscious control of movements. The purpose of this study was to determine how an internal focus (INT), external focus (EXT), and holistic focus (HOL) impact the performance of a standing long jump. Participants (N = 27) completed two baseline jumps followed by two jumps in each focus condition. Jump distance was analyzed in a 6 (Order) × 4 (Focus) mixed ANOVA. Results indicated a significant main effect of focus (p < .001), with EXT and HOL resulting in farther jumps than INT and baseline conditions (p-values < .05). EXT and HOL did not differ significantly from each other, and INT did not differ significantly from baseline. The findings suggest that a holistic focus can be another effective means of avoiding conscious control of movement when an external focus is not practical or desired.

The stress and coping theory posits that in the face of negative consumption situations, individuals experience a sequential process: primary appraisal, secondary appraisal, and behavioral outcomes. Drawing on the theory, the purpose of the study is to test (a) the mediating effects of coping strategies (i.e., secondary appraisal) between the severity of spectator dysfunctional behavior (SDB; i.e., primary appraisal) and revisit intention and (b) the moderating effects of self-construal (i.e., interdependence vs. independence). Across two studies, using a survey experiment (Study 1) and a repeated-measures survey experiment (Study 2), the findings indicate that coping strategies (i.e., active, expressive, and denial coping) significantly and uniquely mediated the relationship between the severity of SDB (high vs. low) and revisit intention. Furthermore, in responding to highly severe SDB, spectators with interdependent self-construal engaged more in active and expressive coping, and less in denial coping and revisit intention than those with independent self-construal. Overall, the present study highlights (a) the importance of coping strategies for a clearer understanding of the SDB–revisit intention relationship and (b) a boundary condition of self-construal for the influences of SDB on coping strategies and revisit intention.
