The study’s objective was to examine the health status, physical activity behaviors, and performance-based functional abilities of individuals classified as being at high or low risk for frailty and to determine which of these characteristics discriminates between the 2 groups. Participants were 78 community-dwelling individuals with an average age of 74 years; 37 were categorized as being at high risk and 42 at low risk for frailty. Logistic-regression analysis indicated that individuals classified as being at high risk for frailty were more likely to have visited the doctor more than 3 times in the past year, experienced a cardiac event, taken more than 4 medications a day, and participated in little or no physical activity. High-risk individuals were more likely to have poor balance, difficulty with mobility, decreased range of motion, poor unimanual dexterity, and difficulty performing activities of daily living than were those classified as being at low risk for frailty.

A salient feature of professional baseball is the absence of minority members serving in managerial positions. Traditionally, it has been argued that minority players did not occupy the playing positions from which managers were generally recruited, thus accounting for their lack of career mobility in baseball. However, examination of the distribution of minority players in major league baseball reveals that they generally appear in high interactor positions in proportion to their general percentage representation among all players. Although managers continue to be selected from high interactor positions, minority players are disregarded by ownership for managerial selection. This study generates an expected frequency of minority representation among managers, based on the positions from which managers are selected and the proportion of minority players occupying those positions.

Aging generally results in muscle and bone atrophy, with accelerated loss in the first few years after menopause contributing to decline in strength, balance, and mobility. This investigation compared the effects of 1 of year periodized high-intensity strength training on a group of less-than-5-years (LF) postmenopausal women (n = 10, mean age 51 years) with its effects on a more-than-10-years (MT) postmenopausal group (n = 11, mean age 60 years). Mean lean body mass, strength, and balance increased over the intervention period for both groups, with no significant intergroup differences. Mean total fat mass significantly decreased for both groups, with no significant difference between groups. Total and regional bone density and mineral content did not significantly change in either group. These results indicate that even during the accelerated muscle-loss period after menopause, women can gain muscle and strength with resistance training to a similar extent as older women.

The purpose of this study was to test the construct validity of the hierarchical levels of self-reported physical disability using health-related variables and physical-performance tests as criteria. The study participants were a community-based sample of 368 adults age 60 years or older. These older adults were grouped into 4 levels according to their physical-disability status (able, mildly disabled, moderately disabled, and severely disabled groups) based on their self-reported measures on the mobility, instrumented activity of daily living (IADL), and activities of daily living (ADL) domains. Health-related variables (body-mass index, number of comorbidities, depression status, mental status, and self-perceived health status) and eight performance-based tests demonstrated significant group differences. Self-reported measures of physical disability can be used to categorize older adults into different stages of physical functional decline.

The purpose was to evaluate perceived sportsmanship behaviors and learning outcomes of a one-day integrated basketball clinic and tournament, titled the Sports for Mutual Admiration and Respect Among Teens (SMART) Games, cooperatively planned and implemented by over 17 agencies. Participants were 55 adolescents (28 without disabilities and 27 with hearing, cognitive/emotional, mobility, or visual disabilities), ages 14 to 18, M age = 15.5. Tournament play was in four divisions, one for each disability, with rules and skills modified accordingly. Quantitative and qualitative data collected afterwards revealed only one significant difference between genders and no significant differences between participants with and without disabilities on the other sportsmanship behaviors (competition, help with skill, equity, fair, effort). Except for ratings on perceived help with skills, sportsmanship ratings were relatively high, ranging from 3.07 to 3.56 on a 4-point scale. Perceived learning outcomes pertained to increased understanding of individual differences and sportsmanship.

The RAMP system of athletic-injury rehabilitation, its name an acronym representing its component phases, has its foundation in the frequent reassessment of the injury condition. The patient is progressed systematically through a sequence of rehabilitation goals: management of the acute responses to injury, restoration of mobility, and successful completion of performance goals. The RAMP system designates the current highest-priority rehabilitation goal as the primary objective and any other goals as secondary. This ensures that the pursuit of 1 rehabilitation goal is not at the expense of another, more currently relevant goal. The RAMP system provides a systematic format to help less-experienced clinicians progress injured athletes through the phases of recovery from injury. Daily reassessment of an injury allows the rehabilitation plan to be current and appropriate. The goal-based progression of the system ensures maximum resolution of each rehabilitation objective, contributing to athletes’ optimal return to sport or activity

Life in the Fourth Age has been typified as a time of continued functional decline and reduced quality of life. Exercise might positively affect this experience. This study explored the exercise experiences of nursing home residents age 86–99 years who participated in a 6-month exercise intervention. An interpretive phenomeno-logical approach was adopted. Twenty-one interviews were held with 14 residents at baseline and 7 residents at follow-up. Although their expectations were initially conservative, by the end of the intervention participants noted improved quality of life through better mobility, decreased fear of falling, and feelings of achievement and success. They valued the program as an opportunity to do something for themselves, to add something to their weekly routine, to meet other people, and to be more active generally. The professionalism of the exercise instructor appears to have been critical, balancing principles of safe and effective practice with the need to ensure that participants had fun in a supportive environment.

The purposes of this study were to determine whether people with and without fibromyalgia (FM) age 50 yr and above showed differences in physical performance and perceived functional ability and to determine whether age, gender, depression, and physical activity level altered the impact of FM status on these factors. Dependent variables included perceived function and 6 performance measures (multidimensional balance, aerobic endurance, overall functional mobility, lower body strength, and gait velocity—normal or fast). Independent (predictor) variables were FM status, age, gender, depression, and physical activity level. Results indicated significant differences between adults with and without FM on all physical-performance measures and perceived function. Linear-regression models showed that the contribution of significant predictors was in expected directions. All regression models were significant, accounting for 16–65% of variance in the dependent variables.

Our purpose in this study was to document the criterion validity of the Fitbit Zip for measuring steps taken by youth with visual impairments (VI). A secondary purpose was to determine whether walking pace, mounting position, or relative position to the user’s mobility device impacted the criterion validity of the device. Fourteen adolescent-aged individuals (M age = 15.4; 13 male and 1 female) with VI participated in this study. Participants wore four Fitbit Zips at different mounting positions and completed two, 2-min walking trials while the lead investigator hand tallied steps. Measurement validity was analyzed using absolute percent error (APE), intraclass correlation coefficients estimated level of conformity, and paired samples t tests and Cohen’s d effect sizes assessed APE relative to mounting positions. Results supported the use of the Fitbit Zip during regular-paced walking; however, caution must be used during activities exceeding regular walking speeds, as devices consistently underestimated steps.

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.
