Over Time

Fewer than 20% of older adults participate in strength training (ST). Barriers to ST participation include not knowing where to go or not having someone to go with. To address these barriers, the authors provided older adults with a peer (older person already participating in ST) to support their engagement. The aim of this pilot randomized controlled trial was to determine whether older adults who were provided with a peer when participating in ST were more likely to be participating in ST 4 weeks postintervention, compared with those receiving ST alone. Fifty-one ST participants were recruited; 40 completed the intervention and postintervention data collection (78.4%). Providing peer support with ST did not significantly increase ST participation (p = .775). However, both groups made significant improvements over time in lower-limb strength and mobility. Participants in either group who continued the ST program (55%) had made additional significant improvements in lower-limb strength and mobility.

Community Dwelling Older Adults

Pre and post testing were conducted on community-dwelling older adults referred to a geriatric day rehabilitation centre (DRC). Consecutive DRC clients were screened for inclusion over a 16-month period and were eligible if: aged 60+ years; cognitively intact; and reason for referral involved spinal or lower limb musculoskeletal impairment, disability or surgery, and/or reduced functional mobility or falls. Clients were excluded if they had a neurological disorder, or did not complete the program. Outcome measures included: lower limb strength; balance; mobility; self-reported pain; activities of daily living; and quality of life. Data were summarised using descriptive statistics and analysed using paired t-tests. Of the 137 participants recruited, 110 were female and the mean age was 79.5 ± 7.3 years. In total, 106 participants completed the DRC program and were assessed at baseline and re-assessed at discharge. The mean length of stay was 12.4 ± 2.9 weeks, with 21.4 ± 5.4 attendances. From baseline to discharge, statistically significant differences were found for all objective measures of physical functioning, balance, and for all lower limb strength tests (P < 0.0001). Glasgow Pain Questionnaire scores demonstrated statistically significant improvements in all five domains of the scale (P < 0.0001). The Barthel Index and Multi-dimensional Functional Assessment Questionnaire both showed a statistically significant improvement in the level of independence in activities of daily living (ADL) (P < 0.05). The Assessment of Quality of Life Questionnaire showed a statistically significant improvement (P = 0.027). The Exercise Benefits/Barriers Scale also showed a statistically significant improvement over DRC attendance (P = 0.005). The Falls Efficacy Scale showed a positive change, but the improvement was not statistically significant (P = 0.80). The study’s results indicate that community-dwelling older adults with physical disabilities and multiple comorbidities who attended the interdisciplinary geriatric DRC, significantly improved their lower limb strength, balance and physical function, and also showed significant decreases in self-reported pain, and improvements in independence in ADL and quality of life. Given the limitations of the current study, further research, in the form of high quality studies with larger sample sizes that involve direct comparisons with other forms of care or against a control group, is needed to determine whether day rehabilitation centre programs provide the optimum mode of rehabilitation for this population in the most cost effective manner.

AbstractThe purpose of the present study was to identify the effects of a strength training program combined with specific plyometric exercises on body composition, vertical jump (VJ) height and strength development of lower limbs in elite male handball players. A 12-week program with combined strength and specific plyometric exercises was carried out for 7 weeks. Twelve elite male handball players (age: 21.6 ± 1.73) competing in the Portuguese Major League participated in the study. Besides the anthropometric measurements, several standardized jump tests were applied to assess VJ performance together with the strength development of the lower limbs in an isokinetic setting. No significant changes were found in body circumferences and diameters. Body fat content and fat mass decreased by 16.4 and 15.7% respectively, while lean body mass increased by 2.1%. Despite small significance, there was in fact an increase in squat jump (SJ), counter movement jump (CMJ) and 40 consecutive jumps after the training period (6.1, 3.8 and 6.8%, respectively). After the applied protocol, peak torque increased in lower limb extension and flexion in the majority of the movements assessed at 90°s-1. Consequently, it is possible to conclude that combining general strength-training with plyometric exercises can not only increase lower limb strength and improve VJ performance but also reduce body fat content.

Abstract Objective: To evaluate the impact of inspiratory muscle training (IMT) on the quality of life, immune response, inspiratory and lower limb muscle strength of older adults. Method: A randomized clinical trial was conducted with 30 institutionalized older adults. They were allocated into two groups: the IMT group (n=15), which underwent IMT with PowerBreathe Classic, using a load of 60% of maximal inspiratory pressure (MIP). This was performed using a 30 repetition protocol, three times a week, for six weeks. The second group was the control group (n=15) which did not perform any type of therapeutic intervention. In both groups, MIP, lower limb strength by sit-up test, quality of life by the SF-36 questionnaire and C-reactive protein (CRP) were evaluated. Results: The results demonstrated the homogeneity between the groups regarding the demographic and clinical variables. The IMT group showed an increase in the variation of MIP (9.20±7.36 cmH2O) compared to the control (0.93±8.79 cmH2O). Improvement was also observed in the sitting and standing test (p<0.05) (Tukey Test) in the difference between the values before and after the IMT. In terms of quality of life, two of the eight SF-36 domains were influenced by the IMT, namely: functional capacity and limitations due to physical factors. There were no changes in CRP in either group. Conclusion: IMT improved the inspiratory muscle strength, lower limb strength and quality of life of institutionalized older adults. These findings reinforce the contribution of this therapy to reducing the deleterious effects of aging.

Objective: This study aimed to investigate the efficacy of high-intensity functional exercise among older adults with dementia. Methods: In this systematic review and meta-analysis of randomized controlled trials, we collected articles published before August 2020 from PubMed, Embase, and the Cochrane Library to evaluate the effect of high-intensity functional exercise on older adults with dementia. Primary outcomes included improvements in balance function and gait performance (speed, cadence, and stride length). The secondary outcomes included lower limb strength, activities of daily living, psychiatric well-being, depression, and cognition. Furthermore, we performed subgroup analysis with two high-intensity functional exercise programs: the Umeå program and Hauer’s program. Results: We identified 15 articles describing six trials including older adults with dementia undergoing high-intensity functional exercise or control activity. The meta-analysis indicated that high-intensity functional exercise, both in Hauer’s program and in the Umeå program, significantly improved balance function (pooled standardized mean difference 0.57, 95% confidence interval 0.31–0.83). Hauer’s program significantly improved gait speed, cadence, stride length, and lower limb strength. Beneficial effects on speed, cadence, and lower limb strength were retained for several months. The Umeå program facilitated activities of daily living and psychiatric well-being, with effects on activities of daily living lasting several months. In the only eligible trial, no effects on cognition were observed. Adverse effects of high-intensity functional exercise were minimal to none. Conclusions: High-intensity functional exercise is generally safe and is recommended for older individuals with mild or moderate dementia to provide benefits in motor performance and daily functioning.
