Maintaining regular physical activity (PA) can be challenging for persons with late effects of polio. This qualitative study of ambulatory persons with late effects of polio explored their perceptions of PA, as well as facilitators of and barriers to PA. Semistructured interviews were conducted with 15 persons and analyzed with content analysis using the International Classification of Functioning, Disability and Health (ICF) as a framework. The participants described positive perceptions of PA and its health benefits. PA was used to prevent further decline in functioning, and the type and frequency of activities had changed over time. Past experiences and personal characteristics impacted PA. Support from close relatives, knowledgeable health care professionals, mobility devices, and accessible environments facilitated PA, whereas impairments, inaccessible environments, and cold weather were the main barriers. To perform PA regularly, persons with late effects of polio may benefit from individualized advice based on their disability and personal and environmental factors.

Confusion of the terms open and closed kinetic chain and scarcity of research comparing kinetic chain exercises that have similar mechanics and loading prompted this case study. Exercises were classified by the boundary condition of the distal segment and presence of an external load. Classifications included a fixed boundary condition with an external load (FEL), a movable boundary with an external load (MEL), and a movable boundary with no external load (MNL). It was hypothesized that if the direction and mass of loading in MEL and FEL exercises were similar, the electromyographic activity of the primary muscle groups involved would be comparable. Muscular activity was monitored from six shoulder muscles during one MNL, four MEL, and five FEL exercises. The results indicated that MEL and FEL exercises having similar biomechanics produced comparable muscular activity. Evaluation and selection of exercises for patients should be based upon mechanics and loading that achieve appropriate muscle activity.

Physical activity is important for maintaining independence and quality of life in older people living in care homes. Little is known about patterns of physical activity or sedentary behavior in this population.
Thirty-three care home residents (82.6 ± 9.2 years) wore an ActiGraph GTX3 accelerometer for seven days, which provided minutes of sedentary behavior and low, light, and moderate-to-vigorous physical activity. Participants undertook the Mini-Mental State Examination and care staff reported activities of daily living (Barthel index) and functional ambulation classification (FAC) for each participant.
Participants spent on average 79% of their day sedentary, 14% in low, 6% in light, and 1% in moderate-to-vigorous physical activity. Activity levels did not significantly differ between days or hours of the day (P > .05).
Levels of physical activity were very low and time being sedentary was high. This study can inform physical activity and sedentary behavior interventions for care homes’ residents.

The purpose of this qualitative study was to explore the experiences of 16 individuals with Parkinson’s disease (PD) partaking in an adapted tango class and the perceived impact on participation and quality of life (QOL). The Ecology of Human Performance and the International Classification of Function were the theoretical frameworks for the study. Data collection involved focus groups conducted during the intervention and at a follow-up six months later. Data analysis followed inductive thematic analysis techniques. The themes addressed living with PD, the class structure and experiences, the participants’ expectations for the class, and the multiple effects experienced by participants at both time periods. The results suggest that adapted tango, when offered in a structured environment with skilled instruction, may improve skills for participation in daily activities and contribute to increased QOL for persons with PD.

The purpose of this paper is to propose a five-stage process for establishing both validity and reliability in new systematic observation instruments. The process is contextualized within the working behaviors of elite level rugby union coaches within the practice setting. The sequential stages began with observer training and progressed through the identification of coaching behaviors through induction (to establish content validity), to establishing face validity through a domain-referenced test. The objectivity and reliability of the developed behavioral classifications are determined through an interobserver agreement test while, finally, the researcher’s ability to reliably reproduce data with the developed instrument is determined using a test/retest intraobserver reliability check. The developed instrument (the Rugby Union Coaches Observation Instrument: RUCOI) is deemed able to record the situationally unique behaviors arising from the nature of the sport and of the elite standard, both of which were considered to impinge upon the pedagogical process in the said context.

The development of the l5-dimension, 56-item Athlete Satisfaction Questionnaire (ASQ) was based on Chelladurai and Riemer’s (1997) classification of facets of athlete satisfaction. Qualitative procedures included item generation, expert judgment, and independent placement of items in relevant facets. Quantitative procedures, item-to-total correlations, exploratory and confirmatory factor analyses, involving 172 undergraduate students and 614 Canadian university athletes, confirmed the construct validity of the scale. Correlations between the ASQ’s subscales and scales of commitment and negative affectivity provided evidence of criterion-related validity. Reliability estimates (Cronbach’s alpha) ranged from .78 to .95. The 15 facets of ASQ encompassed salient aspects of athletic participation, performance (both individual and team), leadership, the team, the organization, and the athlete.

A theory based model was developed for the evaluation of high performance sport centers (HPSCs) in Canada. The model was developed according to de Groot’s (1969) four-phase interpretative-theoretical methodology. The phases of exploration, analysis, classification, and explanation guided the collection of current program evaluation literature and information on the nature of the HPSC program and its past evaluation practices. Appropriate evaluation models from the literature were assessed with respect to the HPSC program’s nature, and a single theoretical-integrative model was developed with corresponding guidelines for HPSC evaluation. The model is described with reference to (a) the role of evaluation at each stage of the HPSC life cycle, (b) the evaluators and decision makers, (c) utilization of the evaluation information, and (d) a general format for guiding the responsible national sport organizations through the important process of evaluation.

The aim of this study was to identify barriers to physical activity among elderly Brazilian women of different socioeconomic status (SES).
A focus-group approach was employed. Subjects were aged, on average, 69.9 years (±6.9; n = 25). SES was measured based on a structured interview and women were grouped according to SES classification. Content analysis was used to categorize mentions of barriers to physical activities followed by descriptive analysis of absolute and relative frequencies of similar reports.
Most common barriers among high-SES elderly women were those within “psychological, cognitive, and emotional” dimensions (33.8%) and “environmental” (29.2%). Among women from lower SES, barriers were inversely ranked, the highest prevalence was verified for environmental (33.8%) and “psychological, cognitive, and emotional” dimensions (25%).
The results highlight that barriers perception varies according to women’s SES, indicating that physical activity promotion strategies must address such differences.

In this manuscript, we use Bitektine’s (2011) theory of organizational social judgments to develop a framework to Capture Perceptions of Organizational Legitimacy (CPOL). We outline a three-stage framework as a method to measure the perceived dimensions on which constituents scrutinize a sport organization’s legitimacy. In stage one of the framework, we defined the organizational context of a nonprofit sport organization in Sydney, Australia to establish the classification, purpose, and relationship of the focal entity to its constituents. In stage two, we distributed a qualitative questionnaire (N = 279) to identify the perceived dimensions on which constituents scrutinized organizational action. In stage 3 we distributed a quantitative questionnaire (N = 860) to test six perceived dimensions, which emerged during stage two of the CPOL framework. The six dimensions explained 63% of respondents’ overall organizational judgment, providing support for the CPOL framework as a context-driven process to measure constituent perceptions of the legitimacy of sport organizations.

Paradoxical performance can be described simply as a sudden decrease in a top athlete’s performance despite the athlete’s having striven for superior performance, such as the lost-skill syndrome in trampolining or “the yips” in golf. There is a growing amount of research on these phenomena, which resemble movement disorders. What appears to be missing, however, is a clear phenomenology of the affected movement characteristics leading to a classification of the underlying cause. This understanding may enable specific diagnostic methods and appropriate interventions. We first review the different phenomena, providing an overview of their characteristics and their occurrence in sports and describing the affected sports and movements. We then analyze explanations for the yips, the most prominent phenomenon, and review the methodological approaches for diagnosing and treating it. Finally, we present and elaborate an action theoretical approach for diagnosing paradoxical performance and applying appropriate interventions.
