Synergistic effect of social support and self-efficacy on physical exercise in older adults

The purpose of the current study was to examine whether the effects of social support on physical exercise in older adults depend on individual perceptions of self-efficacy. Three hundred nine older German adults (age 65-85) were assessed at 3 points in time (3 months apart). In hierarchical-regression analyses, support received from friends and exercise self-efficacy were specified as predictors of exercise frequency while baseline exercise, sex, age, and physical functioning were controlled for. Besides main effects of self-efficacy and social support, an interaction between social support and self-efficacy emerged. People with low self-efficacy were less likely to be active in spite of having social support. People with low support were less likely to be active even if they were high in self-efficacy. This points to the importance of both social support and self-efficacy and implies that these resources could be targets of interventions to increase older adults' exercise.     

Is It Love or Sexual Abuse? Young Adults' Perceptions of Statutory Rape

Adults under age 25 comprise the majority of statutory rape perpetrators, yet we know little about their perceptions of statutory relationships. We assessed 210 (50% male) young adults’ perceptions of statutory rape involving a 15-year-old female adolescent and a male who was either 2, 4, or 6 years older. Across all age gaps, 73.7% of participants felt the relationship should not be a crime. Participants who read about a 4- or 6-year (versus 2-year) age gap perceived the relationship as significantly more of a crime and the older partner as more responsible and in need of legal intervention. Effects were partially mediated by perceptions of the relationship as exploitive. Results suggest a need to educate young adults about statutory rape.     

Comparison of heart-rate and blood-pressure increases during isokinetic eccentric versus isometric exercise in older adults

The authors compared heart-rate and blood-pressure responses to typical isometric (ISO) and isokinetic (90 degrees /s) eccentric (ECC) resistance-training protocols in older adults. Twenty healthy older adults (74 +/- 5 years old) performed randomly ordered ISO and isokinetic ECC exercise (3 sets of 10 repetitions) at a target intensity of 100 % of their peak ISO torque value. Heart rate and systolic (SBP) and diastolic (DBP) blood pressures were recorded continuously, and mean arterial pressure (MAP) and rate-pressure product (RPP) were calculated. ECC peak torque (139 +/- 33 N. m) was significantly greater than ISO peak torque (115 +/- 26 N. m; p <.001). All variables increased significantly (p <.001) during both ISO and ECC exercise. Changes in SBP, DBP, MAP, and RPP were significantly greater during ISO exercise than during ECC exercise (p <.001). Clinically, an isokinetic ECC exercise program enables older adults to work at the same torque output with less cardiovascular stress than ISO exercise.     

Social-cognitive determinants of physical activity attendance in older adults

The present study evaluated whether, and to what extent, the constructs implicated in the theory of planned behavior could predict behavioral intention to exercise and exercise-class attendance of older adults (age 65-90 years) already enrolled in a physical activity program. The study also evaluated whether including self-efficacy judgments might improve the predictive capacity of the model. Participants (N = 1,095) were randomly sampled Italian volunteers from exercise classes for older adults. First, they completed questionnaires assessing the above-mentioned constructs. Then, class attendance was recorded during the following 3 months. Results indicated a substantial correspondence between the model and the data. Perceived behavioral control and self-efficacy were the strongest predictors of behavioral intention, whereas attitudes and subjective norms only partially contributed to its prediction. The inclusion of self-efficacy improved the predictive capacity of the overall model. Finally, results showed a weak relation between behavioral intention and attendance rate in physical activity sessions.     

Community exercise program for older adults recovering from hip fracture: a pilot study

Community-based rehabilitative exercise programs might be an effective means to improve functional outcomes for hip-fracture patients. The purpose of this study was to evaluate the effectiveness of a community exercise program (CEP) for older adults recovering from hip fracture. Twenty-five older adults (mean age 80.0 +/- 6.0 years; 24 women; 71 +/- 23 days post-hip fracture) participated in this pilot study (17 exercise, 8 control). The CEP involved functional stepping and lower extremity-strengthening exercises. Control participants received only standard outpatient therapy. Measures of functional mobility, balance confidence, falls efficacy, lower extremity strength, and daily physical activity were evaluated at baseline and at 16 weeks. Improvements for self-reported physical activity, mobility, balance, and knee-extensor strength were observed for the CEP group. This study demonstrated that a CEP is beneficial for community-dwelling older adults post-hip fracture.     

The effects of strength training on memory in older adults

The authors examined whether resistance training has an effect on working memory span. Participants included 210 community-residing older adults with at least one disability from the Strong for Life program, a randomized controlled trial that examined the effects of home-based resistance exercise. Memory was assessed with the WAIS backward digit span at baseline and 3 and 6 months into the intervention. Although there were no differences between the experimental treatment and control groups in average levels of memory change, within the treatment group change in resistance level during the intervention was a significant predictor of memory change, controlling for age, education, sex, and disability level. The results suggest that strength training can benefit memory among older adults, especially when using higher resistance levels.     

Environmental changes to increase physical activity: perceptions of older urban ethnic-minority women

Despite the numerous benefits of physical activity, older adults continue to be more sedentary than their younger counterparts, and sedentary behavior is more prevalent among older racial and ethnic minorities than among Whites. This study used the nominal group technique (NGT) to examine participants' perceptions of what neighborhood environmental changes would encourage greater physical activity for older African American and Hispanic women. Participants age 50-75 years were recruited from 2 urban community health clinics. Nine NGT sessions (45 participants) were conducted. The women were asked what changes in their neighborhood environment would encourage them to become more physically active. Responses to the research question were tabulated, and qualitative analysis was used to identify themes and categories. Major categories were physical environment changes, safety, and activities/social support. Although the physical environment received the greatest number of points, concerns for personal safety cut across categories. Participants indicated the need for more facilities in which to be active.     

Motives for and barriers to physical activity among older adults with mobility limitations

The purpose of this study was to investigate what older adults with severe, moderate, or no mobility limitation consider motives for and barriers to engaging in physical exercise. Community-dwelling adults (N=645) age 75-81 years completed a questionnaire about their motives for and barriers to physical exercise and answered interview questions on mobility limitation. Those with severely limited mobility more often reported poor health, fear and negative experiences, lack of company, and an unsuitable environment as barriers to exercise than did those with no mobility limitation. They also accentuated disease management as a motive for exercise, whereas those with no or moderate mobility limitation emphasized health promotion and positive experiences related to exercise. Information about differences in motives for and barriers to exercise among people with and without mobility limitation helps tailor support systems that support engagement in physical activity among older adults.     

Effects of multicomponent training on functional fitness in older adults

The purpose of this study was to evaluate the effects of a 9-week supervised multicomponent exercise program on functional fitness and body composition in independent older adults. Forty-two adults age 60-86 years were randomly assigned to an exercise or a control group and were evaluated before and after training. The training program consisted of 3 sessions of walking, strengthening, and flexibility exercises per week. The multicomponent training program resulted in significant (p < .005) improvements on the chair stand, arm curl, 6-min walk, and up-and-go tests. The findings of this study indicate that a 9-week training program increased upper and lower body strength, aerobic endurance, and agility/dynamic balance in older adults. The most affected components of functional fitness were lower body strength and aerobic endurance. There was no effect of the 9-week training on body composition.     

The gallon-jug shelf-transfer test: an instrument to evaluate deteriorating function in older adults

This study examined the validity, reliability, and discriminatory capacity of the gallon-jug shelf-transfer (GJST) test. Six hundred fifty-three independent-living older adults (463 women age 72.9 +/- 7.0 years, 190 men age 74.3 +/- 6.7 years) participated. Participants moved five 1-gallon jugs (approximately 3.9 kg) from a knee-high to a shoulder-high shelf as quickly as possible. The GJST showed an exponential performance decline with age, and there were significant correlations between the GJST and common functional tests (p<.001). High within-day and between-days reliability was detected. The test also detected differences resulting from training status (p<.01) and training protocols (p<.05). The GJST is a valid, reliable, inexpensive, safe, and easily administered clinical test for identifying physically vulnerable elders who could benefit from interventions such as exercise to improve their physical capacities and maintain independence.     

The effects of life events and interpersonal loss on exercise adherence in older adults

Associations of life events and interpersonal loss with participation in home- and group-based exercise were studied in 97 older adults (64 % women, 70.2 +/- 4.1 years). Life events were assessed with a modified Social Readjustment Rating Scale at baseline and 6 and 12 months. Exercise logs and class-attendance records documented exercise participation. Participants experienced 3.62 +/- 3.56 unique life events over the course of the study, and 28 participants reported an interpersonal loss (5 men, 23 women). Number of life events was negatively associated with home-based exercise participation (p <.05); among women, this association approached significance (p =.06) for class-based exercise. Women who experienced an interpersonal loss had lower class-based participation than those who did not (p =.02), but home-based participation rates were unaffected. Life events, particularly interpersonal loss, appear to have a negative impact on exercise in women, and this effect appears greater for class-based than for home-based exercise.     

Exercise intervention designed to improve strength and dynamic balance among community-dwelling older adults

Loss of balance and falling are critical concerns for older adults. Physical activity can improve balance and decrease the risk of falling. The purpose of this study was to evaluate a simple, low-cost exercise program for community-dwelling older adults. Sixteen senior adults were evaluated using the Senior Fitness Test for measures of functional strength, aerobic endurance, dynamic balance and agility, and flexibility. In addition, measures of height, weight, resting blood pressure, blood lipids, and cognitive function were obtained. Participants then attended a 10-week exercise class including stretching, strengthening, and balance-training exercises. At the completion of the program, significant improvements were observed in tests measuring dynamic balance and agility, lower and upper extremity strength, and upper extremity flexibility. The results indicate that exercise programs such as this are an effective, low-cost solution to improving health and factors that affect falling risk among older adults.     

An integrated dementia intervention for Korean older adults

Called dotage in Korea, dementia is primarily characterized by cognitive impairments. Secondary manifestations include mental-emotional problems, including depression. This study was designed to examine the effects of an integrated dementia intervention for Korean older adults. The intervention is composed of cognitive stimulation training, exercise, music, art, and horticultural therapy. Participants included 38 older adults with mild dementia. Twenty were assigned to the experimental group and 18 to the control group. Participants in the experimental group attended 18 program sessions. Significant differences were found postintervention between the two groups in measures of cognitive function, depression levels, and mental-emotional health. The findings indicate that this integrated dementia intervention can be applied to help older adults with mild dementia.     

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.     

Age Similarities in Interpersonal Perception and Conversation Ability

Older adults tend to perform worse on emotion perception tasks compared to younger adults. How this age difference relates to other interpersonal perception tasks and conversation ability remains an open question. In the present study, we assessed 32 younger and 30 older adults’ accuracy when perceiving (1) static facial expressions, (2) emotions, attitudes, and intentions from videos, (3) and interpersonal constructs (e.g., kinship). Participants’ conversation ability was rated by coders from a videotaped, dyadic problem-solving task. Younger adults were more accurate than older adults perceiving some but not all emotions. No age differences in accuracy were found on any perception task or in conversation ability. Some but not all of the interpersonal perception tasks were related. None of the perception tasks predicted conversation ability. Thus, although the literature suggests a robust age difference in emotion perception accuracy, this difference does not seem to transfer to other interpersonal perception tasks or interpersonal outcomes.     

Affective and self-efficacy responses to acute aerobic exercise in sedentary older and younger adults

This study examined the psychological responses to an acute bout of aerobic exercise in sedentary older and younger adults. Eighteen young (mean age 24 years) and 15 older adults (mean age 64 years) completed a 20-min bout of stationary cycling at 65% of VO2peak. Affective responses were assessed before, during, and immediately after exercise. Participants'exercise self-efficacy beliefs were assessed before and immediately after exercise. Both groups reported reduced pleasant feeling states and self-efficacy and increased physical exhaustion in response to acute exercise. Older adults also demonstrated a significant decrease in revitalization during and after cycling. Correlation analyses revealed that self-efficacy was related to feelings of fatigue during exercise and postexercise feelings of energy and fatigue. Both groups reported negative shifts in affect and self-efficacy during and 5 min after cycling.Acute affective and self-efficacy responses might influence one's motivation to adopt and maintain regular physical activity. The relationship between these acute responses and physical activity behavior across the life span warrants future inquiry.     

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.     

Coping strategies used by LGB older adults in facing and anticipating health challenges: A narrative analysis

ABSTRACT

Given that lesbian, gay, and bisexual (LGB) older adults face notable health disparities compared to their heterosexual counterparts, there is a need for understanding how LGB adults cope with health challenges in late life. The current study analyzes narratives from nine LGB adults age 65 and older living in an urban area in the Southeast United States. Participants spoke of coping strategies related to health promotion behaviors, shifting perspectives of health and body, trusting in spirituality for comfort, and accepting the end of life. We discuss implications for social services professionals who work with older LGB adults and for future research.
