Multidimensional Physical Self-Concept Of Athletes With Physical Disabilities, Deborah R. Shapiro, Jeffrey J. Martin
Multidimensional Physical Self-Concept Of Athletes With Physical Disabilities, Deborah R. Shapiro, Jeffrey J. Martin
Kinesiology, Health and Sport Studies
The purposes of this investigation were first to predict reported PA (physical activity) behavior and self-esteem using a multidimensional physical self-concept model and second to describe perceptions of multidimensional physical self-concept (e.g., strength, endurance, sport competence) among athletes with physical disabilities. Athletes (N = 36, M age = 16.11, SD age = 2.8) completed the Physical Self- Description Questionnaire. Participants reported mostly positive perceptions of self-esteem, global physical self-concept, endurance, body fat, sport competence, strength, flexibility, and physical activity (Ms ranging from 3.9 to 5.6 out of 6). Correlations indicated a number of significant relationships among self-esteem …
Developing A Caring Coaching Climate Fosters Confidence, E. Whitney G. Moore
Developing A Caring Coaching Climate Fosters Confidence, E. Whitney G. Moore
Kinesiology, Health and Sport Studies
When athletes buy-in to a positive training climate their training effort, enjoyment, and desire to continue all increase. This article focuses on practical approaches coaches can use today to promote a safe, personalized, and respect-filled atmosphere – integral building blocks for developing a successful caring climate.

Research has shown the human brain is organized into separable functional networks during rest and varied states of cognition, and that aging is associated with specific network dysfunctions. The present study used functional magnetic resonance imaging (fMRI) to examine low-frequency (0.008 < f < 0.08 Hz) coherence of cognitively relevant and sensory brain networks in older adults who participated in a 1-year intervention trial, comparing the effects of aerobic and nonaerobic fitness training on brain function and cognition. Results showed that aerobic training improved the aging brain’s resting functional efficiency in higher-level cognitive networks. One year of walking increased functional connectivity between aspects of the frontal, posterior, and temporal cortices within the Default Mode Network and a Frontal Executive Network, two brain networks central to brain dysfunction in aging. Length of training was also an important factor. Effects in favor of the walking group were observed only after 12 months of training, compared to non-significant trends after 6 months. A non-aerobic stretching and toning group also showed increased functional connectivity in the DMN after 6 months and in a Frontal Parietal Network after 12 months, possibly reflecting experience-dependent plasticity. Finally, we found that changes in functional connectivity were behaviorally relevant. Increased functional connectivity was associated with greater improvement in executive function. Therefore the study provides the first evidence for exercise-induced functional plasticity in large-scale brain systems in the aging brain, using functional connectivity techniques, and offers new insight into the role of aerobic fitness in attenuating age-related brain dysfunction.
Validation Of The Organizational Culture Assessment Instrument: An Application Of The Korean Version, Yun Seok Choi, Minhee Seo, David Scott, Jeffrey J. Martin
Validation Of The Organizational Culture Assessment Instrument: An Application Of The Korean Version, Yun Seok Choi, Minhee Seo, David Scott, Jeffrey J. Martin
Kinesiology, Health and Sport Studies
The purpose of this study was to examine the psychometric properties of the Korean version of the Organizational Culture Assessment Instrument (OCAI) based on the Competing Values Framework (CVF). More specially, cultural equivalence between the Korean version and the original English version of the OCAI was evaluated using 39 bilingual Koreans. Next, a field test was conducted to examine scale reliability and construct validity of the Korean version of the OCAI using 133 organizational members from the Korean Professional Baseball League (KPBL). The findings indicate that the Korean version was successfully translated, items maintained the same meaning of the original …
