There is a paucity of evidence regarding the effects of sport and physical activity on wellbeing in dementia. The present study is the first known study to involve golf with this population. People with dementia (n = 10) and carers (n = 5) participated in a 6-week golf program, facilitated by golf center staff (n = 3). Multiple avenues of data collection were utilized and were subject to thematic analysis. Five central themes were identified: emotion, respite, losing the “dementia” label, friendship/camaraderie, and improving relationships. Underlying subthemes were also identified, while potential links between themes were highlighted. Themes were also considered in terms of which participants (person with dementia, carer, and staff) provided evidence for each theme. This study presents preliminary support for the role of golf to enhance the psychological and social wellbeing of people with early stages of dementia, carers, and staff. Potential mechanisms and future research are discussed.

Compromised attentional resources during perceived fatigue has been suggested to alter motor control. The authors determined if measures of postural control and gait are predicted by state and trait physical and mental fatigue and energy, and how these relationships are modified by sex, sleep quality, and physical activity. Young adults (n = 119) completed the Modified Clinical Test of Sensory Integration, overground walking, and questionnaires to quantify fatigue and energy, sleep quality, and physical activity. Regression models indicated that trait fatigue, trait energy, and sleep quality were predictors of postural control (p ≤ .02, R 2 ≥ .04). State fatigue, state energy, and sex were predictors of gait (p ≤ .05, R 2 ≥ .03). While the variance explained was low (3–13%), the results demonstrate perceptions of fatigue and energy may influence posture and gait.

Background: The purpose of this study was to investigate the accuracy of the published prediction equations for determining level overground walking energy cost in young adults. Methods: In total, 148 healthy young adults volunteered to participate in this study. Resting metabolic rate and energy expenditure variables at speeds of 4, 5, and 6 km/h were measured by indirect calorimetry, walking energy expenditure was estimated by 3 published equations. Results: The gross and net metabolic rate per mile of level overground walking increased with increased speed (all P < .01). Females were less economical than males. The present findings revealed that the American College of Sports Medicine and Pandolf et al equations significantly underestimated the energy cost of overground walking at all speeds (all P < .01) in young adults. The percentage mean bias for American College of Sports Medicine, Pandolf et al, and Weyand et al was 12.4%, 16.8%, 1.4% (4 km/h); 21.6%, 15.8%, 7.1% (5 km/h); and 27.6%, 12%, 6.6% (6 km/h). Bland–Altman plots and prediction error analysis showed that the Weyand et al was the most accurate in 3 existing equations. Conclusions: The Weyand et al equation appears to be the most suitable for the prediction of overground walking energy expenditure in young adults.

The mental health benefits of physical activity may relate more to the context of the behavior, rather than the behavior of being active itself. The association between varsity sport (VS) participation, depression, and anxiety symptoms was explored using data from 70,449 high school students from the Cannabis use, Obesity, Mental health, Physical activity, Alcohol use, Smoking, and Sedentary behavior study. The model adjusted for potential covariates; interactions by sex and participation in outside of school sport (OSS) were explored. Overall, 70% and 24% of respondents met or exceeded cutoff values for depression and anxiety, respectively. Students participating in VS had lower symptoms of anxiety and depression compared with nonparticipants. Results were consistent regardless of OSS participation; associations were strongest among students who participated in both VS and OSS and males. Participation in VS may prove beneficial for the prevention and/or management of depression or anxiety symptoms, particularly among males. An additive beneficial effect of OSS on depression and anxiety scores may exist.

Intradialytic exercise is feasible and yields substantial clinical benefits in middle-aged patients. However, evidence is scarce in older hemodialysis patients. Objective: To assess the feasibility and clinical benefits of supervised, intradialytic exercise in older patients. Methods: Multicenter one-arm feasibility study. The main outcome was feasibility (ease of recruitment, dropout rate, adherence, affective valence, and adverse events). The secondary outcomes were physical capacity (five-repetition sit-to-stand, 60-s sit-to-stand tests, and grip strength), quality of life (36-Item Short-Form Health Survey), quality of sleep (Pittsburgh Sleep Quality Index), depressive symptoms (Beck Depression Inventory), and dialysis efficacy (Kt/V and urea reduction ratio). Results: About 79% of the screened patients agreed to participate (n = 25, 73 [66–77] years). The dropout rate was high (32%), but adherence remained high among the participants who completed the study (94%). Improvements were found in the five-repetition sit-to-stand (p < .001), 60-s sit-to-stand tests (p = .028), 36-Item Short-Form Health Survey mental component score (p = .008), depressive symptoms (p = .006), and quality of sleep (p = .035). Conclusion: Supervised intradialytic exercise seems safe and beneficial in older patients.

The addition of a load during walking requires changes in the movement pattern. The investigation of the dynamic joint stiffness behavior may help to understand the lower limb joints’ contribution to these changes. This study aimed to investigate the dynamic stiffness of lower limb joints in response to the increased load carried while walking. Thirteen participants walked in two conditions: unloaded (an empty backpack) and loaded (the same backpack plus added mass corresponding to 30% of body mass). Dynamic stiffness was calculated as the linear slope of the regression line on the moment–angle curve during the power absorption phases of the ankle, knee, and hip in the sagittal plane. The results showed that ankle (P = .002) and knee (P < .001) increased their dynamic stiffness during loaded walking compared with unloaded, but no difference was observed at the hip (P = .332). The dynamic stiffness changes were different among joints (P < .001): ankle and knee changes were not different (P < .992), but they had a greater change than hip (P < .001). The nonuniform increases in lower limb joint dynamic stiffness suggest that the ankle and knee are critical joints to deal with the extra loading.

This study aimed to translate the Pictorial Scale of Physical Self-Concept for Brazilian Children (PSPPS-BR) into the Brazilian-Portuguese language, conduct a transcultural adaptation of it, and investigate its validity. Method: The authors adopted the reverse translation procedures to obtain the PSPPS-BR’s Brazilian-Portuguese version. Three motor behavior experts assessed the scale items’ clarity and pertinence. Ten professionals participated in the face validity study. Children (N = 300; 150 girls and 150 boys; 8–10 years old; M age = 9.0, SD = 0.81) were randomly selected from six schools in Brazil and assessed using the PSPPS-BR, the Pictorial Scale of Perceived Movement Skill Competence, and the Self-Perception Profile for Children. The children (N = 100) were reassessed for test–retest reliability. Results: High clarity and pertinence agreement among experts (content validity coefficient from 98.4% to 100%; Gwet’s agreement coefficient from .85 to 1.00, p < .001) and among professionals (content validity coefficient clarity: 83–100%, relevance: 90–100%) were obtained. The confirmatory factorial analysis showed adequate model fits (root mean square error of approximation = .067; comparative fit index = .968; Tukey–Lewis index = .949). Polychoric correlations showed an adequate internal consistency for total scale (α = .78) and items (alpha from .73 to .78). The intraclass coefficient correlation shown strong test–retest reliability (intraclass correlation coefficient > .95). Conclusion: The PSPPS-BR showed adequate validity and reliability for Brazilian children.

The relationship between the quality of movement, considering different global and universal basic patterns of movement and cognition domains in older adults remain unclear. The current study explored this association in physically inactive older women. In total, 187 participants, aged 60–70 years (mean = 64.9, SD = 6.9 years), were recruited from a physical education program in a public university. The older adults performed the following tests: Functional Movement Screen, Montreal Cognitive Assessment, and Modified Baecke Questionnaire for the Older Adults. The regression analysis showed an association between age (β = −0.11, 95% confidence interval, CI, [−0.10, 0.30], p = .03); visuospatial abilities (β = 0.36, 95% CI [0.24, 1.23], p < .001); language (β = 0.23, 95% CI [0.20, 1.08], p < .001); and orientation domains (β = 0.13, 95% CI [0.11, 1.22], p = .016) of the Montreal Cognitive Assessment and the Functional Movement Screen. The quality of movement was related to both age and cognitive performance, such as the visuospatial abilities, language, and orientation domains, in physically inactive older women.

Reliability and sensitivity of reaction time (RT) during quasi-realistic soccer situations was explored in 10 professional soccer players (skilled; age = 20.9 ± 3.6 years) and 10 males without soccer experience (nonskilled; age = 23.4 ± 0.5 years). The participants were instructed to react as fast as possible to a stimulus presented via the video-based method while standing on force platforms. RT was computed as the difference between the instant when the rate of force development of any leg reaches 5% of its maximal value and the instant of stimulus presentation. The results revealed acceptable to high reliability of RT (intraclass correlation coefficient median = .90; coefficient of variation ≤ 5.83%), and shorter RT for skilled compared with nonskilled participants in three out of eight comparisons (effect size range = 1.00–1.41). The video-based methods can be confidently used to assess the RT in soccer players.
