Effects of an 8-week multimodal exercise program on strength, flexibility, and golf performance in 55- to 79-year-old men

Substantial research has indicated the beneficial effect of physical activity on physical fitness and activities of daily living in older adults, but none have investigated the effects on performance of recreational activities. This investigation studied the effect of an exercise program on fitness and golf-clubhead speed in older men. Thirty-one golfers (mean age 65.1 +/- 6.2 years) were randomly assigned to a treatment (n = 19) or control (n = 12) group. The treatment group completed an 8-week strength and flexibility program. Assessments included 10-RM muscle strength; selected range-of-motion (ROM) measurements; and golf-clubhead speed (CHS). ANCOVA revealed significant differences between groups (p <.005) for all strength measurements and several ROM measurements. CHS was significantly different (p <.05) between groups after the intervention. Mean CHS improved from 85.0 to 87.1 miles/hr (136.8 to 140.2 km/hr). These results indicate that a strength and flexibility program can improve golf performance in older adults.     

The impact of body-mass index and steps per day on blood pressure and fasting glucose in older adults

The purpose of this study was to investigate the combined impact of obesity and physical activity (PA) on the health of older adults. Pedometer-determined steps/d, body-mass index (BMI), resting blood pressure, and fasting glucose (FG) were assessed in 137 older adults (69.0 +/- 8.9 yr). The active group (>4,227 steps/d) had lower systolic blood pressure (SBP; p = .001), diastolic blood pressure (DBP; p = .028), and FG (p < .001) than the inactive group (< or = 4,227 steps/d). The normal-BMI group (18.5-24.9 kg/m2) had lower SBP (p < .001) and DBP (p = .01) than the obese group (> or =30 kg/m2). There were no differences in SBP (p = .963) or DBP (p = 1.0) between active obese and inactive normal-BMI groups. The active obese group, however, had a more favorable FG than the inactive normal-BMI group (chi 2 = 18.9, df = 3, p = .001). Efforts to increase PA of older adults should receive the same priority as reducing obesity to improve BP and FG levels.     

The effect of guided relaxation and exercise imagery on self-reported leisure-time exercise behaviors in older adults

The purpose of this study was to examine the effects of a 6-wk intervention that used guided relaxation and exercise imagery (GREI) to increase self-reported leisure-time exercise behavior among older adults. A total of 93 community-dwelling healthy older adults (age 70.38 ± 8.15 yr, 66 female) were randomly placed in either a placebo control group or an intervention group. The intervention group received instructions to listen to an audio compact disk (CD) containing a GREI program, and the placebo control group received an audio CD that contained 2 relaxation tracks and instructions to listen to music of their choice for 6 wk. Results revealed that listening to a GREI CD for 6 wk significantly increased self-reported leisure-time exercise behaviors (p = .03). Further exploration of GREI and its effects on other psychological variables related to perceived exercise behaviors may substantiate its effectiveness.     

The Role of the Environment in Sedentary Behavior in Community-Dwelling Older Adults

To compare amounts of sedentary behavior and physical activity in adults residing in planned group residential settings to those residing in private homes, this study recruited 31 older adults who resided in planned group residential settings (n = 13) and in private homes (n = 18). Daily activities were measured using the SenseWear Armband for 7 days. Estimates of the duration of daily activities performed across sedentary, light, and moderate-to-vigorous intensities were captured. It was found that participants in planned group residential settings were older (age 85.9 ± 3.5 vs. 78.3 ± 7.2; p = 0.001) and spent more time in sedentary behaviors (12.7 ± 1.5 vs. 11.3 ± 1.6; p = 0.02) than participants in private homes. The difference was attenuated slightly after controlling for age and wear time (adjusted difference 1.2 ± 0.6 hours, p = 0.06). Thus, adults residing in planned group residential settings, which provide supportive services, were more sedentary than adults residing in private homes. The environment in which older adults live may contribute to sedentary behavior.     

Outcomes of a multicomponent physical activity program for sedentary, community-dwelling older adults

This single-group repeated-measures pilot study evaluated the effects of a 10-wk, multicomponent, best-practice exercise program on physical activity, performance of activities of daily living (ADLs), physical performance, and depression in community-dwelling older adults from low-income households (N = 15). Comparison of pretest and posttest scores using a one-tailed paired-samples t test showed improvement (p < .05) for 2 of 3 ADL domains on the Activity Measure-Post Acute Care and for 6 physical-performance measures of the Senior Fitness Test. Repeated-measures ANOVA revealed significant main effects for 3 of 8 physical activity measures using the Yale Physical Activity Scale. Retention rate was 78.9%, and the adherence rate for group sessions was 89.7%. Results suggest that participation in a multicomponent, best-practice physical activity program may positively affect sedentary, community-dwelling older adults' physical activity, ADL performance, and physical performance.     

Systematic review of functional training on muscle strength,physical functioning,and activities of daily living in older adults

Exercise programs are often recommended for preventing or delaying late-life disability. Programs that incorporate functional training, which uses movements similar to performing activities of daily living, may be suitable for such recommendation. The purpose of this systematic review was to examine the effects of functional training on muscle strength, physical functioning, and activities of daily living in older adults. Studies in three electronic databases (MEDLINE, CINAHL, and SPORTDiscus) were searched, screened, and appraised. Thirteen studies were included in the review. These studies vary greatly in participant recruitment criteria, functional training content, and selection of comparison groups. Mobility exercises were the most common element in functional training across studies. Results show beneficial effects on muscle strength, balance, mobility, and activities of daily living, particularly when the training content was specific to that outcome. Functional training may be used to improve functional performance in older adults.     

Challenges to Aging in Place: Understanding Home Maintenance Difficulties

Age-related declines in capabilities may compromise older adults’ ability to maintain their homes, threatening successful aging in place. Structured interviews were conducted with 44 independently living older adults (mean age = 76.1, standard deviation = 4.7) to discuss difficult home maintenance tasks and how they managed those tasks. Solutions to managing difficulties were categorized as person-related or environment-related. The majority (85%) of responses were person-related solutions. An understanding of the specific challenges that older adults face in maintaining their homes can guide redesign efforts and interventions to effectively support older adults’ desire to age in place.     

Gardening as a potential activity to reduce falls in older adults

This study examines whether participation in gardening predicts reduced fall risk and performance on balance and gait-speed measures in older adults. Data on adults age 65 and older (N = 3,237) from the Health and Retirement Study and Consumption and Activities Mail Survey were analyzed. Participants who spent 1 hr or more gardening in the past week were defined as gardeners, resulting in a total of 1,585 gardeners and 1,652 nongardeners. Independent t tests, chi square, and regression analyses were conducted to examine the relationship between gardening and health outcomes. Findings indicate that gardeners reported significantly better balance and gait speed and had fewer chronic conditions and functional limitations than nongardeners. Significantly fewer gardeners than nongardeners reported a fall in the past 2 yr. The findings suggest that gardening may be a potential activity to incorporate into future fall-prevention programs.     

Training effects on motor–cognitive dual-task performance in older adults

This systematic review investigated whether healthy older adults benefit from training interventions in motor–cognitive dual-task (DT) situations and which specific aspects of the intervention and/or task selection contribute to training benefits. Training effects were analysed with regard to the training programme (e.g., general ST or DT training) and task conditions (e.g., standing or walking, complexity of secondary cognitive task). Literature was searched via OVIDsp (Medline, EMBASE, PsycINFO). DT studies were included by the following criteria: (1) investigation of at least one motor task, (2) assessment of DT performance outcomes on standing or walking, (3) conduction of an intervention, and (4) investigation of older adults in an experimental–control group design or an old–young comparison. Thirteen studies met all inclusion criteria. Four types of interventions were identified: (1) general single-task (ST) motor training, (2) specific ST motor training, (3) general DT training, and (4) task-related (specific) DT training. For DT standing conditions only DT interventions improved motor performance, whereas DT walking also benefits by ST training. Most benefits on motor and cognitive performance seem to be reached by DT training interventions whereas a GST produced lowest effects. Thus, balance orientated motor and cognitive DT performance in healthy older adults can be improved by performance related exercises. Furthermore, to reach beneficial effects, it seems necessary that the training intervention includes a certain level of exercise load such as rising difficulties, appropriate intensity and duration, a certain level of task specificity, and variable task prioritization. The transfer of training effects into everyday situations needs to be further investigated.     

Challenges to Aging in Place: Understanding Home Maintenance Difficulties

Age-related declines in capabilities may compromise older adults' ability to maintain their homes thus threatening successful aging in place. Structured interviews were conducted with forty-four independently living older adults (M(age) = 76.1, SD = 4.7) to discuss difficult home maintenance tasks and how they managed those tasks. Solutions to managing difficulties were categorized as person-related or environment-related. The majority (85%) of responses were person-related solutions. An understanding of the specific challenges that older adults face in maintaining their homes can guide redesign efforts and interventions to effectively support older adults' desire to age in place.     

Leadership in physical activity groups for older adults: a qualitative analysis

The purpose of this study was to determine whether a theory-based framework could be used to deductively identify and understand the characteristics of motivational leaders of physical activity groups for older adults. Participants were 23 older adults (mean age = 78.5 +/- 8.0 years, 65% women). An interview-guide approach was employed to elicit older adults' thoughts on important characteristics of physical activity group leaders. The data suggested that effective leaders are those whom the participants feel are properly qualified, are able to develop a personal bond with participants, and can use their knowledge and the group to demonstrate collective accomplishments. It was concluded that the findings could be used to extend the leadership activities beyond the traditional technical performance and individual feedback to include activities of social integration. Furthermore, the conceptual framework identified can serve as a valuable tool in guiding future researchers in their examination of leadership in physical activity groups for older adults.     

Rate of perceived exertion as a tool to monitor cycling exercise intensity in older adults

The purpose of this study was to determine the efficacy of rate of perceived exertion (RPE) to monitor exercise intensity in older adults. Middle-aged (46.9 +/- 7.0 years, n = 24) and older women (75.5 +/- 3.8 years, n = 29) performed a graded maximal exercise test on a cycle ergometer while RPE, oxygen uptake, heart rate, and blood lactate levels were measured. The Pearson's product moment correlation coefficient between RPE and oxygen uptake for each stage of the graded exercise test was calculated for each participant. The mean coefficient for the older group (r =.954) was similar to that of middle-aged group (r =.963). The autocorrelation coefficient was much lower (r =.411) in the older group than in the middle-aged group (r =.871). Variability in RPE through the graded exercise test was similar between the two groups. In conclusion, RPE was strongly associated with oxygen uptake in the older group. These results indicate that RPE is effective in monitoring exercise intensity in older adults.     

Attitudes Toward Divorce,Commitment, and Divorce Proneness in First Marriages and Remarriages

A random multistate sample of married individuals (N = 1,931) was used to explore whether more positive attitudes toward divorce and weaker commitment to marriage may contribute to the greater instability of remarriages than first marriages. Remarried adults, whether or not they brought children from a previous union into the remarriage, reported marital quality (happiness and conflict) equal to those in first marriages. They also reported more positive attitudes toward divorce, which were associated with higher divorce proneness (i.e., thinking about and taking actions toward divorce). Marriage type interacted with marital quality to predict divorce proneness, such that the association between low marital quality and divorce proneness was stronger for remarried individuals than for those in first marriages. This suggests that remarried adults may be more likely than adults in first marriages to take steps toward divorce when experiencing marital distress, possibly reflecting a weaker commitment to marriage.     

Does yoga engender fitness in older adults? A critical review

Interest in yoga is growing, especially among older adults. This review critically summarizes the current literature to investigate whether physical fitness and function benefits are engendered through the practice of yoga in older adults. A comprehensive search yielded 507 studies; 10 studies with 544 participants (69.6 ± 6.3 yr, 71% female) were included. Large variability in yoga styles and measurement outcomes make it challenging to interpret results across studies. Studies reported moderate improvements for gait (ES = 0.54, 0.80), balance (ES = 0.25-1.61), upper/lower body flexibility (ES = 0.25, 0.70), lower body strength (ES = 0.51), and weight loss (ES = 0.73, 0.99).Yoga may engender improvements in some components of fitness in older adults. However, more evidence is needed to determine its effectiveness as an alternative exercise to promote fitness in older adults. Further investigation into yoga as an exercise activity for older adults is warranted.     

The beneficial effects of different types of exercise interventions on motor and cognitive functions in older age: a systematic review

The decline in cognitive and motor functions with age affects the performance of the aging healthy population in many daily life activities. Physical activity appears to mitigate this decline or even improve motor and cognitive abilities in older adults. The current systematic review will focus mainly on behavioral studies that look into the dual effects of different types of physical training (e.g., balance training, aerobic training, strength training, group sports, etc.) on cognitive and motor tasks in older adults with no known cognitive or motor disabilities or disease. Our search retrieved a total of 1095 likely relevant articles, of which 41 were considered for full-text reading and 19 were included in the review after the full-text reading. Overall, observations from the 19 included studies conclude that improvements on both motor and cognitive functions were found, mainly in interventions that adopt physical-cognitive training or combined exercise training. While this finding advocates the use of multimodal exercise training paradigms or interventions to improve cognitive-motor abilities in older adults, the sizeable inconsistency among training protocols and endpoint measures complicates the generalization of this finding.     

The effect of functional circuit training on physical frailty in frail older adults: a randomized controlled trial

The purpose of this study was to evaluate whether a 12-wk functional circuit-training program (FCT) could alter markers of physical frailty in a group of frail community-dwelling adults. Fifty-one individuals (31 women, 20 men), mean age (± SD) 84 (± 2.9) yr, met frailty criteria and were randomly assigned into groups (FCT = 26, control group [CG] = 25). FCT underwent a 12-wk exercise program. CG met once a week for health education meetings. Measures of physical frailty, function, strength, balance, and gait speed were assessed at Weeks 0, 12, and 36. Physical-frailty measures in FCT showed significant (p < .05) improvements relative to those in CG (Barthel Index at Weeks 0 and 36: 73.41 (± 2.35) and 77.0 (± 2.38) for the FCT and 70.79 (± 2.53) and 66.73 (± 2.73) for the CG. These data indicate that an FCT program is effective in improving measures of function and reducing physical frailty among frail older adults.     

Is discrimination an equal opportunity risk?: racial experiences, socioeconomic status, and health status among black and white adults

Using the 2004 Behavioral Risk Factor Surveillance System, we explore the relationship between racial awareness, perceived discrimination, and self-rated health among black (n = 5,902) and white (n = 28,451) adults. We find that adjusting for group differences in racial awareness and discrimination, in addition to socioeconomic status, explains the black-white gap in self-rated health. However, logistic regression models also find evidence for differential vulnerability among black and whites adults, based on socioeconomic status. While both groups are equally harmed by emotional and/or physical reactions to race-based treatment, the negative consequences of discriminatory experiences for black adults are exacerbated by their poorer socioeconomic standing. In contrast, the association between racial awareness and self-rated health is more sensitive to socioeconomic standing among whites. Poorer health is more likely to occur among whites when they reflect at least daily on their own racial status-but only when it happens in tandem with mid-range educational achievement, or among homemakers.     

Stair-ascent performance in elderly women: effect of explosive strength training

Explosive-type strength training may alter kinetics and neuromuscular activity during stair ascent in elderly women. This may improve functional ability. Nineteen women (69.7 ± 3.4 yr) were randomly allocated to strength training (TG; twice per wk, 12 wk) or a control group (CG). Stair ascent was assessed at self-chosen (AFV), standardized (ASV), and maximal velocity (AMV) pre- and posttraining. Ground-reaction force (GRF) and EMG quantified kinetics and neuromuscular activity. After training, TG increased AMV and AFV velocity by 8% (p = .02) and 17% (p= .007), respectively (TG vs. CG; p< .05). This was accompanied by elevated rectus femoris EMG (from 21% to 48%, p< .047). At AFV, TG increased GRF first peak force 4% (p= .047), and CG increased second peak force 5% (p = .036). Muscle coactivation remained unaltered in both groups. Explosive-type strength training led to enhanced stair-climbing performance at maximal and self-chosen speed, reflecting an improved functional ability.     

Pilot Testing a Cognitive-Behavioral Protocol on Psychosocial Predictors of Exercise,Nutrition, Weight,and Body Satisfaction Changes in a College-Level Health-Related Fitness Course

Abstract

Objective: Small-scale pilot testing of supplementing a required college health-related fitness course with a cognitive-behavioral exercise-support protocol (The Coach Approach). Participants: Three classes were randomly assigned to Usual processes (n = 32), Coach Approach–supplemented: Mid-size Groups (n = 32), and Coach Approach–supplemented: Small Groups (n = 34) conditions. Methods: Repeated-measures analyses of variance (ANOVAs) assessed overall and between-class changes in the behavioral/physiological factors of exercise, fruit/vegetable intake, and body mass index (BMI); and the psychosocial factors of self-regulation, exercise self-efficacy, mood, and body satisfaction. Dependent t tests evaluated within-class changes. Multiple regression analyses tested prediction of exercise by changes in self-regulation, self-efficacy, and mood. Results: Significant improvements in self-regulation and fruit/vegetable intake were found in all classes. The Coach Approach–supplemented classes demonstrated significant increases in exercise. Significant improvements in BMI, self-efficacy, and body satisfaction were found in only The Coach Approach–supplemented: Small Groups class. Psychosocial changes predicted increased exercise. Self-regulation was the strongest contributor. Conclusions: Overall, results were positive and warrant more comprehensive testing.     

The Self-Regulation of Gambling

Despite the prevalence of gambling world-wide, relatively few individuals become problem gamblers. Additionally many problem gamblers recover without professional assistance. The current study aim was to examine how individuals self-manage their gambling through (a) assessing frequency of use of a range of self-regulation strategies (b) examining how these strategies cluster and (c) exploring relationships between strategies, gambling frequency, amount spent and problem gambling severity. A sample of 303 gamblers was recruited, over-sampling for problem gamblers as assessed by the Problem Gambling Severity Index (PGSI) of the Canadian Problem Gambling Index (mean age 26.4 years, SD = 10.1 years; 119 males, 184 females; 238 social gamblers, 63 problem gamblers, 2 unclassified). They rated extent of usage of 27 gambling self-management techniques and completed the PGSI and other gambling measures. Factor analysis of items produced five factors, named Cognitive Approaches, Direct Action, Social Experience, Avoidance and Limit Setting. The relationships between these factors and key gambling variables were consistent with hypotheses that problem gamblers trying to reduce their gambling would be more likely to use the strategies than other gambler groups. The potential for developing the factors into a Gambling Self-regulation Measure was explored.
