Depression is a disabling, prevalent condition. Physical activity programs may assist depression management in older people, ameliorate co-morbid conditions and reduce the need for antidepressants. The UPLIFT pilot study assessed the feasibility of older depressed people attending a community-based progressive resistance training (PRT) program. The study also aimed to determine whether PRT improves depressive status in older depressed patients.
                A randomised controlled trial was conducted. People aged > or = 65 years with depressive symptoms were recruited via general practices. Following baseline assessment, subjects were randomly allocated to attend a local PRT program three times per week for 10 weeks or a brief advice control group. Follow-up assessment of depressive status, physical and psychological health, functional and quality of life status occurred post intervention and at six months.
                Three hundred and forty six people responded to the study invitation, of whom 22% had depressive symptoms (Geriatric Depression Scale, GDS-30 score > or = 11). Thirty two people entered the trial. There were no significant group differences on the GDS at follow-up. At six months there was a trend for the PRT intervention group to have lower GDS scores than the comparison group, but this finding did not reach significance (p = 0.08). More of the PRT group (57%) had a reduction in depressive symptoms post program, compared to 44% of the control group. It was not possible to discern which specific components of the program influenced its impact, but in post hoc analyses, improvement in depressive status appeared to be associated with the number of exercise sessions completed (r = -0.8, p < 0.01).
                The UPLIFT pilot study confirmed that older people with depression can be successfully recruited to a community based PRT program. The program can be offered by existing community-based facilities, enabling its ongoing implementation for the potential benefit of other older people. The Regenerate pilot study explored whether a 10-week, community-based progressive resistance training (PRT) program could reduce depressive symptoms in depressed chronic stroke survivors.
                Participants were screened for depressive status using the PHQ-9 and confirmed by psychiatric assessment. Eligible people (n = 45) were randomised to PRT or a waiting-list comparison group. The PRT program included two high intensity sessions/week for 10 weeks at a community-based gymnasium. Depressive status, physical and mental health and quality of life were measured at baseline, 10 weeks and 6 months. Muscle strength was assessed using 1 repetition maximum (1-RM) for upper and lower limbs.
                The participants' median age was 69 years: 27 were male. The intervention group had lower depression scores than the comparison group at all time points. At 6-month follow-up, there was a trend for PRT participants to be more likely to be no longer depressed than the comparison group, but the difference was not significant after adjusting for baseline scores. There were modest improvements in health and wellbeing over time, but many scores were lower than reported in non-depressed people. Intervention participants demonstrated significant improvements in strength. Program adherence was good: on average 75% of the 10-week program was completed.
                The intervention appeared to be feasible within a community-based setting. To optimize stroke recovery and improve the quality of life of stroke survivors, health professionals should continue to focus on helping survivors' mental health recovery as well their physical rehabilitation.
                (c) 2008 John Wiley & Sons, Ltd. Although exercise has been shown to relieve depression, little is known about its mechanism or dose-response characteristics. We hypothesized that high intensity progressive resistance training (PRT) would be more effective than either low intensity PRT or standard care by a general practitioner (GP) in depressed elderly persons, and that high intensity PRT would provide superior benefits in quality of life, sleep quality, and self-efficacy.
                Sixty community-dwelling adults >60 years with major or minor depression were randomized to supervised high intensity PRT (80% maximum load) or low intensity PRT (20% maximum load) 3 days per week for 8 weeks, or GP care.
                A 50% reduction in the Hamilton Rating Scale of Depression score was achieved in 61% of the high intensity, 29% of the low intensity, and 21% of the GP care group (p =.03). Strength gain was directly associated with reduction in depressive symptoms (r = 0.40, p =.004), as was baseline social support network type (F = 3.52, p =.015), whereas personality type, self-efficacy, and locus of control were unrelated to the antidepressant effect. Vitality quality-of-life scale improved more in the high intensity group than in the others (p =.04). Sleep quality improved significantly in all participants (p <.0001), with the greatest relative change in high intensity PRT (p =.05).
                High intensity PRT is more effective than is low intensity PRT or GP care for the treatment of older depressed patients. Depression in elderly people may be contributed to by the multiple losses of aging. Exercise has the potential to positively impact many of these losses simultaneously. We tested the hypothesis that progressive resistance training (PRT) would reduce depression while improving physiologic capacity, quality of life, morale, function and self-efficacy without adverse events in an older, significantly depressed population.
                We conducted a 10-week randomized controlled trial of volunteers aged 60 and above with major or minor depression or dysthymia. Subjects were randomized for 10 weeks to either a supervised PRT program three times a week or an attention-control group.
                A total of 32 subjects aged 60-84, mean age 71.3 +/- 1.2 yr, were randomized and completed the study. No significant adverse events occurred. Median compliance was 95%. PRT significantly reduced all depression measures (Beck Depression Inventory in exercisers 21.3 +/- 1.8 to 9.8 +/- 2.4 versus controls 18.4 +/- 1.7 to 13.8 +/- 2, p = .002; Hamilton Rating Scale of Depression in exercisers 12.3 +/- 0.9 to 5.3 +/- 1.3 versus controls 11.4 +/- 1.0 to 8.9 +/- 1.3, p = .008). Quality of life subscales of bodily pain (p = .001), vitality (p = .002), social functioning (p = .008), and role emotional (p = .02) were all significantly improved by exercise compared to controls. Strength increased a mean of 33% +/- 4% in exercisers and decreased 2% +/- 2% in controls (p < .0001). In a multiple stepwise regression model, intensity of training was a significant independent predictor of decrease in depression scores (r2 = .617, p = .0002).
                PRT is an effective antidepressant in depressed elders, while also improving strength, morale, and quality of life. To evaluate the efficacy of supervised high-intensity progressive resistance training (PRT) on lower extremity strength, function, and disability in older, long-term stroke survivors.
                Forty-two volunteers aged 50 years and above, 6 months to 6 years after a single mild to moderate stroke, were randomized into either a control group of upper extremity stretching or a PRT group that received a 12-week supervised high-intensity resistance training program consisting of bilateral leg press (LP), unilateral paretic and nonparetic knee extension (KE), ankle dorsiflexion (DF), and plantarflexion (PF) exercises. Functional performance was assessed using the 6-minute walk, stair-climb time, repeated chair-rise time, and habitual and maximal gait velocities. Self-reported changes in function and disability were evaluated using the Late Life Function and Disability Instrument (LLFDI).
                Single-repetition maximum strength significantly improved in the PRT group for LP (16.2%), paretic KE (31.4%), and nonparetic KE (38.2%) with no change in the control group. Paretic ankle DF (66.7% versus -24.0%), paretic ankle PF (35.5% versus -20.3%), and nonparetic ankle PF (14.7% versus -13.8%) significantly improved in the PRT group compared with the control. The PRT group showed significant improvement in self-reported function and disability with no change in the control. There was no significant difference between groups for any performance-based measure of function.
                High-intensity PRT improves both paretic and nonparetic lower extremity strength after stroke, and results in reductions in functional limitations and disability. The recommendations for exercise training and physical activity for older adults include cardiovascular and resistance training components (CVT and RT, respectively). The purpose of the present investigation was to compare the fitness benefits of concurrent CVT and RT with those attained through an equivalent duration of CVT or RT alone.
                Thirty-six participants (ages 60-84) were assigned to a control group or to one of three exercise treatment groups. The treatment groups exercised three times per week for 12 wk using RT (N = 11), CVT (N = 10), or CVT and RT (BOTH, N = 9). Pre- and post-training, participants performed a submaximal exercise test (GXT), five repetition-maximum strength tests (5RM), and the AAHPERD functional fitness test for older adults.
                All exercise treatment groups revealed lower resting heart rate and rate-pressure product; lower exercise diastolic blood pressure and rating of perceived exertion; increased GXT duration; increased leg, back, and shoulder 5RM scores; and improved AAHPERD flexibility, coordination, and cardiovascular endurance scores. The exercise treatment groups responded differently on the following: RT and BOTH enhanced arm and chest strength more than CVT; and BOTH enhanced AAHPERD strength and agility scores more than CVT or RT.
                Concurrent CVT and RT is as effective in eliciting improvements in cardiovascular fitness and 5RM performance as CVT or RT, respectively. Moreover, incorporating both CVT and RT in exercise programs for older adults may be more effective in optimizing aspects of functional fitness than programs that involve only one component. To test the feasibility and efficacy of current guidelines for multimodal exercise programs in older adults.
                Randomized, controlled trial.
                Retirement village.
                Thirty-eight subjects (14 men and 24 women) aged 76.6 +/- 6.1.
                A wait list control or 10 weeks of supervised exercise consisting of high-intensity (80% of one-repetition maximum (1RM)) progressive resistance training (PRT) 3 days per week, moderate-intensity (rating of perceived exertion 11 to 14/20) aerobic training 2 days per week, and progressive balance training 1 day per week.
                Blinded assessments of dynamic muscle strength (1RM), balance, 6-minute walk, gait velocity, chair stand, stair climb, depressive symptoms, self-efficacy, and habitual physical activity level.
                Higher baseline strength and psychological well-being were associated with better functional performance. Strength gains over 10 weeks averaged 39+/-31% in exercise, versus 21+/-24% in controls (P=.10), with greater improvements in hip flexion (P=.01), hip abduction (P=.02), and chest press (P=.04) in the exercise group. Strength adaptations were greatest in exercises in which the intended continuous progressive overload was achieved. Stair climb power (12.3+/-15%, P=.002) and chair stand time (-7.1+/-15%, P=.006) improved significantly and similarly in both groups. Reduction in depressive symptoms was significantly related to compliance (attendance rate r=-0.568, P=.009, PRT progression in loading r=-0.587, P=.02, and total volume of aerobic training r=-0.541, P=.01), as well as improvements in muscle strength (r=-0.498, P=.002).
                Robust physical and psychological adaptations to exercise are linked, although volumes and intensities of multiple exercise modalities sufficient to cause significant adaptation appear difficult to prescribe and adhere to simultaneously in older adults. There are few studies published that combine the interventions of physical training and nutrition. The aim of the present study was to describe the impact of a physical and nutritional intervention program for frail community- dwelling elderly people over the age of 75.
                Ninety-six community-dwelling elderly people (58 women) were randomized to four different groups: i) a physical training program (aerobic, muscle strength, balance), ii) a nutritional intervention program (individually targeted advice and group sessions), iii) a combination of these interventions, and iv) a control group. At baseline subjects were screened for physical performance such as muscle strength, balance, mobility and activities of daily living, as well as nutritional aspects such as energy intake, body weight and fat-free mass. These measurements were repeated immediately after the intervention, which lasted for 12 weeks, and after another 6 months.
                The intention-to-treat analysis indicated significant improvements in lower- extremity muscle strength in both training groups compared with the nutrition group at 1st follow-up. There were small significant changes for some of the balance measurements in the training group without nutrition treatment. The nutrition intervention did not show any significant results.
                This study shows the positive effect on lower-extremity muscle strength directly after the intervention. Balance training most probably needs to be more individualized in order to be effective for frail elderly people. Further studies are needed, with larger sample sizes, to investigate the effects of these types of interventions before any further conclusions can be drawn. Falls, loss of health-related quality of life and physical capacity, reduced participation in activities of daily living, and increased fear of falling are all potential outcomes for older adults discharged from hospital. A low-cost video based exercise programme may address this.
                This study was a randomized controlled trial with blinded outcomes assessment and a six-month follow-up.
                Participants were older adults (>65 years) using a mobility aid discharged from a tertiary hospital in Brisbane, Australia, without referral for community-based rehabilitation services.
                A digital video disk-based programme encompassing six exercise types each with six levels of difficulty. A home visit from a project physiotherapist was conducted to ensure patient safety. Control group patients received usual care.
                Falls, health-related quality of life, participation in activities of daily living, physical capacity and fear of falling.
                Study participants (n = 53, 19 intervention, 34 control) experienced decreasing health-related quality of life, several falls (72), and lower levels of participation in activities of daily living over the six-month follow-up. The intervention group did not differ significantly from the control group in terms of the outcomes examined, though a non-significant reduction in the rate of falls was observed. Intervention group participants complied with the exercise programme well during the first two weeks following discharge from hospital but then reduced their compliance levels thereafter.
                The intervention may be beneficial for reducing the rate of falls in this patient population though further research with a larger sample size is indicated.
This review provides evidence that PRT is an effective intervention for improving physical functioning in older people, including improving strength and the performance of some simple and complex activities. However, some caution is needed with transferring these exercises for use with clinical populations because adverse events are not adequately reported.
