Objective: To present a systematic review of randomized controlled trials which summarizes the effects of community-based resistance, balance, and multi-component exercise interventions on the parameters of functional ability (e.g., lower extremities muscle strength, balance performance and mobility).
Methods: This PROSPERO-registered systematic review (registration no. CRD42023434808) followed the PRISMA guidelines. Literature search was conducted in Cochrane, Embase, Ovid Medline, PEDro, Pubmed, Science Direct, Scopus and Web of Science. We included RCTs that investigated the following interventions: lower extremity strengthening, balance and multi-component exercise interventions on ambulatory community-dwelling adults aged ≥65 years.
Results: Lower extremity strengthening exercises revealed significant effects on the strength of lower extremity, balance outcomes and mobility. Balance exercises reduce the rate of injurious falls, improve static, dynamic and reactive balance, lower extremity strength as well as mobility. Multi-component exercise training reduces medically-attended injurious falls and fallers, incidence of falls, fall-related emergency department visits as well as improves mobility, balance, and lower extremity strength.
Conclusion: Physical exercises are effective in improving the components of balance, lower extremity strength, mobility, and reducing falls and fall-related injuries. Further research on fall prevention in low-income countries as well as for older adults in vulnerable context is needed.
1. Introduction
One-third of older adults aged 65 years or over fall each year, and 50% of them fall repeatedly (1). According to the World Health Organization (WHO) (2), falls are the second leading cause of unintentional injury deaths globally, and the literature shows that 40% of community-dwelling older adults who are over 65 years experience fall accidents annually (3). In Europe, every year approximately 36,000 older adults (65 years and above) die from falls (data 2010–2012). Of these, 88% of cases are related to people aged 75 years or older and 59% of cases are related to women (4).
Physical inactivity and deficits in functional ability (e.g., reduced lower limbs muscular strength and impaired balance ability) have been identified as independent contributors to falls and fall-related injuries (e.g., head injuries and hip fractures) among older adults (5–8). Even though they are critical risk factors for older adults, they are modifiable and preventable through exercises (7, 9, 10). Falls also have economic burdens such as medications, hospital admissions, and extended rehabilitation services (2, 11).
Exercise training is broadly recognized as an appropriate intervention strategy for improving functional performance in older adults, reducing the aforementioned risk factors, and consequently minimizing the risk of falling (12–14). Additionally, the reduction of physical inactivity has been shown to have positive economic impacts on national, social, and individual levels (15).
Cognitive decline also occurs during normal aging (16), which is considered a significant factor in increased functional dependence and fewer activities of daily living among older adults (17). According to previous studies, older adults who exercised three times a week for 6 months showed improvements in global and executive cognitive functions as well as a general deceleration of the aging process (18, 19).
Accordingly, the WHO recommends that older adults aged over 65 years adopt an active lifestyle that ensures the performance of physical activity of moderate intensity for a minimum of 150 min weekly (20, 21), as well as engage in fall prevention exercises (22). This moderate amount of physical activity has been shown to reduce the risk factors associated with falls by up to 50% by reducing functional limitation in older persons, and eventually reducing the risk of falls (13).
Several studies (23–28) have concluded that strength, balance, and aerobic-based training is effective in reducing falls among older adults in general and up to 50% in community-dwelling older adults specifically, with gains that may last as the training is maintained (29). In their clinical guideline for the prevention of falls, the American Geriatrics Society and British Geriatrics Society Clinical Practice recommend that the prevention of fall risk factors should include gait training, resistance, and balance exercises (30).
Studies on resistance exercises reported their effectiveness in mitigating reduced muscle strength, and that these types of exercises are considered an essential element of a multi-component exercise fall prevention strategy (31, 32). Furthermore, there is a considerable body of literature on balance exercises and their effectiveness in reducing the risk of falling among community-dwelling older adults (23, 33–36).
Previous systematic reviews and meta-analyses explored the effects of exercise on fall prevention among older people. However, these reviews and meta-analyses were conducted in a younger age group (60 years and over) (23, 27) compared with our present review and in participants with Parkinson’s disease, stroke, and cognitive impairment (26) who had mixed living settings (living in the community, nursing homes, and higher dependency places of residence) (35, 37). They concluded that exercises as a stand-alone intervention can significantly reduce the rate of falls (23, 26, 27, 35, 37) and the risk of falling (23, 27).
To the best of our knowledge, despite the current interest in the topic, there is a lack of systematic reviews on fall prevention strategies that address the effectiveness of exercise training, specifically on ambulatory community-dwelling older adults aged 65 years or older. Therefore, our current review aims to present a systematic review of randomized controlled trials (RCTs) that summarizes the effects of resistance, balance, and multi-component exercise interventions. These interventions consist mainly of combined resistance and balance exercises in addition to one or more types of exercises, namely, aerobic, walking, and weight-bearing, on the parameters of functional ability (e.g., lower extremities muscle strength, balance performance, and mobility), which accordingly prevent falls in ambulatory community-dwelling adults aged 65 years and over.
2. Methods
The current systematic review is presented in accordance with the guidelines of PRISMA 2020 (Preferred Reporting Items for Systematic Reviews and Meta-Analyses literature search extension) (38). The review was registered on PROSPERO with the following registration no. CRD42023434808.
2.1. Data sources and search strategies
Two consecutive searches were conducted by two researchers (MS and ZN) independently. The initial search was limited to studies in English published from 1 January 2015 to 30 December 2020, then the search was conducted again on 7 August 2021 for publications published from 1 January 2021 to 7 August 2021 in the following electronic databases: Cochrane Central Register of Controlled Trials, Embase, Ovid Medline, PEDro, Pubmed, Science Direct, Scopus, and Web of Science. The search was supplemented by a manual review of reference lists from included primary studies and review articles to find additional studies on the subject (Table 1).
Table 1. Search strategy.
All research papers were first retrieved, and Zotero 6.0.26 (a reference manager created at the Roy Rosenzweig Center for History and New Media at George Mason University, Virginia, United States) was utilized to remove duplicates. Next, titles and abstracts were screened independently by two researchers (MS and ZN), and finally, the full texts of the remaining studies were assessed to determine eligibility. Disagreements between the two researchers were resolved through discussion and mutual consent, or by a third assessor (MH). After the abstract and full-text analysis, the Cohen’s Kappa-coefficient (K score) was calculated to weigh the level of agreement between the two reviewers.
2.2. Eligibility criteria
Based on PICOTS, studies were included if they were written in English, were RCTs on community-dwelling adults aged ≥65 years, and included the following interventions: lower limb strengthening exercises, balance exercises, and multi-component exercise interventions that consist of resistance and balance exercises in addition to one or more types of exercises, namely, aerobic, walking, and weight-bearing. Studies were excluded if (I) they involved residents of nursing homes and inpatients, (II) involved participants with a diagnosis of multiple sclerosis, cancer, Parkinson’s or Alzheimer’s disease, stroke, recent fractures, vision or cognitive impairments, or other chronic conditions associated with aging, (III) they were on non-human participants, (IV) they were based on interventions of video games, web-based programs, Tai Chi, Otago exercise program, multifactorial components that combine exercises and non-exercise interventions, yoga, dance therapy, or water-based exercise program, and (V) were non-RCTs, cohort studies, cross-sectional studies, reviews, conference abstract/papers, surveys, opinion pieces, commentaries, books, periodicals, editorials, case studies, non-peer-reviewed articles, masters dissertations, and doctoral theses.
2.3. Data extraction
Two reviewers independently extracted the following data from each study: author, publication year, study title, aim and design, number and demographic data of participants, the type of intervention such as lower limb strengthening exercise training, balance exercise training, and multi-component exercise training, duration, frequency, and settings of intervention, equipment used, outcome measures, results, and limitations.
2.4. Risk of bias assessment
One review author (MS) carried out the risk of bias assessment using Cochrane’s Risk of bias tool among six domains: random sequence generation, allocation concealment, blinding of participants and personnel, blinding of outcome assessment, incomplete outcome data, and selective reporting (38).
3. Results
3.1. Study selection
From 1,161 yielded studies, 288 duplicates were excluded. Then, following title and abstract screening, another 729 were excluded. The remaining studies were assessed against the inclusion and exclusion criteria and 29 studies in total were eligible to be included in the systematic review (Figure 1). To measure the inter-rater reliability between the two reviewers, a K score was calculated at abstract level (0.82) and at full-text level (0.86), which showed a high level of agreement. The included studies involved 4,330 participants, of which 4,121 adhered to the end of the studies and were analyzed for the outcome measures. The participants’ average age ranged from 66.4 to 82.4 years, and all were community-dwelling older adults. The 29 included studies were only RCTs.
Figure 1. Flow of the studies screened.
3.2. Setting and training equipment
Interventions were mainly conducted in gyms, exercise halls, community facilities (5, 32, 39–41), combined gyms, home-based locations (42–45), and laboratories (46, 47). Some studies did not report the intervention setting, however, a gym/community setting was likely from the description of interventions (48–65).
A variety of training equipment was used: resistance training machines (32, 45, 46, 49, 52, 53, 55, 61), recumbent trainer, seated stationary cycle ergometer, treadmills, climber, bike recline (32, 47, 49, 52), weighted equipment such as cuff and vest weights (5, 32, 39–41, 45, 50, 55, 63, 65), elastic bands/tubing (39–41, 53, 56, 58, 59), free weights (45, 52), body weight (5, 44, 48), balls (39, 42, 44, 50, 51), step-boards (5, 39, 45), chairs (5, 50), equipment used for balance training such as tripping boards, slipping tiles, balance foams, wedged soft mat, soft pads, non-inverted BOSU® balls, inverted BOSU® balls, balance cushions, balance beams, semicircular blocks, Posturomed®, wobble boards, and inflatable discs (39–41, 43, 48, 52, 53, 57). One study reported that they used small, low-cost equipment as well (e.g., towels and bottles) (44), whereas five studies did not clearly report any equipment used, however, they could have merely used body weight for exercises (54, 60, 62, 64, 65).
3.3. Dosage of exercise programs
The duration of exercise interventions ranged from 15 min (44) to 90 min (53, 64, 65) per session, the frequency of interventions ranged from once a day (43) to five times a week (62), and the duration of the exercise programs ranged from 1 week (47, 57) to 2 years (5, 42).
3.4. Results according to intervention
3.4.1. Lower limb strengthening exercise training
Seven of the included studies contained lower limb strengthening exercises as the only intervention or one of a multi-component intervention. They used different modalities and showed significant improvements in lower extremities strength (using dynamometer, five times sit to stand test, and chair rise test), balance (activities specific balance confidence (ABC) scale, berg balance scale, one leg standing test, Y-balance test, and functional reach test), mobility (6-minute walk test, timed up and go test (TUGT), and 30-second chair stand test), days survived without a fall or near-fall, gait (functional gait assessment) (32, 46, 52–54, 56, 59). One study did not show significant change in static balance (single leg stance assessment with eyes closed on the dominant and single leg stance assessment with eyes closed on the non-dominant) or eccentric strength (maximal eccentric strength) (46). Another study did not show significant improvement in TUGT, except when exercise was combined with neuromuscular electrical stimulation (54). Table 2 shows a complete summary of the key data extracted from the studies on strengthening exercise interventions.

3.4.2. Balance exercise training
Ten studies compared balance exercise interventions to non-active controls (usual daily activities and social programs), and those that used different balance interventions methods showed significant improvements in muscle strength [chair standing test (CST), four square step test (FSST), and 2-min step test (2MST)], balance [single leg stance test (SLST), one leg standing test, tandem stance test, ABC scale, modified Clinical Test of Sensory Organization and Balance, local dynamic stability, and balance recovery], gait and mobility (TUGT, 6-min walk test, five times chair stand test, and functional reach test), lower rate of falls, reduction in the rate ratio of all falls, and slip falls (42, 43, 47, 50, 53, 57, 60, 62, 64, 65).
One RCT compared an enhanced balance program with a standard balance program on sit-to-stand test repetitions. The study revealed no significant difference between the two groups in sit-to-stand test repetitions. There was a statistically significant improvement in sit-to-stand test repetitions from pre- to post-intervention for both standard balance and enhanced balance exercise groups (39).
A study in this review scrutinized the effects of an 8-week square-step exercise in older fallers. The composite balance score as a marker of postural control was significantly higher in the square-step exercise group compared with the vestibular exercise group. Adaptation test was utilized to assess the ability to control motor reactions after an unexpected change in position (dynamic balance). Square step exercise did not show significant results compared with vestibular exercise neither in toes up nor in toes down (48). Table 3 shows a complete summary of the key data extracted from the studies on balance exercise interventions.

3.4.3. Multi-component exercise training
Seven studies that compared multi-component exercise interventions to non-active controls showed significant improvements in lower extremities strength (isometric leg extension strength, CST, and knee extensors strength), static balance (backward walking, Romberg test, and postural sway), proactive balance (functional reach test), reactive balance, and mobility, as well as showed lower medically-attended injurious falls and a decrease in the frequency of fallers (5, 44, 45, 49, 51, 55, 58).
An RCT by Li and colleagues aimed to assess the effectiveness of multimodal exercise (MME) training consisting of balance, aerobics, strength, and flexibility activities relative to stretching exercises (SE) in reducing the incidence of falls in older adults. MME showed a significantly lower incidence of falls (16 per 100 person-months) compared with SE (27 per 100 person-months). For total walking duration in instrumented-TUGT and short physical performance battery, which measured repeated chair stands, three increasingly challenging standing balance tasks, and a 4-m speed walk, the MME group performed significantly better than those in the SE group (40).
Another RCT aimed to assess the longer-term effectiveness of multimodal exercise (MME) training consisting of balance, aerobics, strength, and flexibility activities relative to therapeutic Tai Ji Quan: Moving for Better Balance (TJQMBB) and SE in decreasing injurious falls among older adults at high risk of falling. For moderate and serious injurious falls, MME demonstrated significantly lower incidence compared with SE (41). One RCT examined the effect of an 8-week-long two-exercise routine: 1. Strength and core stability training, which consisted of core stability (planks, climb exercise, and supine bridge) and strengthening exercises and 2. Strength and aerobic training, which consisted of aerobic exercises (bike recline and treadmill) and strengthening exercises. Lower limb strength was assessed by a 30-s chair stand test, aerobic ability by 2MST, and finally static balance by SLST. In the strength and core stability training group, tests revealed significant differences in the 30-s chair stand test, in the left SLST, in the right SLST, and finally in 2MST (61). In the strength and aerobic training group, there was only a significant difference between pre- and post-tests for 2MST. Others examined the effectiveness of an 8-week complex exercise program on walking ability and fall efficacy compared to a general exercise program. The complex exercise program consisted of resistance exercises to strengthen trunk, stretching exercises to increase flexibility, and aerobic exercises. FSST was used to assess complex walking ability. Figure-of-8 walking test (F8WT) is another test that is used to measure curved walking ability. During F8WT, the subject is asked to walk a “figure of 8” pattern around cones, the number of steps and time to accomplish the test are considered. For FSST and F8WT, in the complex exercise program and general exercise program there was significant difference between pre and post-tests. In addition, there was a significant difference between the complex exercise program and general exercise program for FSST, but not for F8WT. The results signify complex exercise program effectiveness in improving balance skills while changing direction and following a curved line (63). Table 4 shows a complete summary of the key data extracted from the studies on multi-component exercise interventions.

3.4.4. Risk of bias
The result of the risk of bias summary and risk of bias graph are available in Supplementary Figures S1, S2, respectively. For random sequence generation and allocation concealment, more than 50% of the studies showed unclear risks as they were not clearly described. For blinding of participants and personnel and blinding of outcome assessment, slightly over 50% of the studies showed low risk. Almost 75% of the studies had low risk in the domain of incomplete outcomes. All studies except one demonstrated a low risk for selective reporting.
4. Discussion
This systematic review aimed to present a summary of the effectiveness of resistance, balance, and multi-component exercise interventions, which consist mainly of combined resistance and balance exercises in addition to one or more types of exercises, namely, aerobic, walking, and weight-bearing, on the parameters of functional ability (e.g., lower extremities muscle strength, balance performance, and mobility), which accordingly prevent falls in ambulatory community-dwelling adults aged 65 years or above.
Although poor muscle strength is an established risk factor for falls (66), it has been found that the inclusion of strength training had no substantial effect on falls (23, 35, 37) when the person has sufficient strength to avoid falling (35). Moreover, strength training as a single intervention showed no evidence to be effective in fall prevention (23). However, strength training is likely to offer older adults with longer-term fall prevention and other health gains (37, 67–69), and these types of exercises are recommended to be included in addition to other training (i.e., balance training) (37). To be effective, strength training should provide a certain amount of resistance in an exercise and maximally 10–15 repetitions should be completed before reaching muscle fatigue (67). A systematic review concluded that there is a positive association between the type of resistance exercise and the effect on strength gain and that resistance exercises also help in preserving functional independence and quality of life in older adults (70). In a previous study, eccentric strengthening exercise, when compared to traditional strengthening exercise, yielded greater improvements in muscle strength, balance, and mobility (71). Concerning the improvement in balance abilities after strengthening exercises, previous studies showed that they are able to improve balance recovery and dynamic and static balance skills in older adults, and consequently prevent falls (72, 73), whereas for others, the use of strengthening exercises alone failed to show clear effects on balance abilities (68, 74). One RCT in this review found that resistance exercises when done on either stable or unstable surfaces using exercise machines or free weights, demonstrated significant improvements in muscle power and reactive balance, with no significant differences between the three interventions, though gains in muscle strength (isometric leg extension strength) and gains in muscle power (chair rise test) were greater in exercises accomplished on unstable surfaces. Therefore, the authors recommended following resistance training with unstable surfaces and moderate instability as in machine-based unstable resistance training if the goal is to enhance muscle strength and the power of the lower extremities. While if great load is a concern and limited to a degree, then free-weight unstable resistance training is recommended (52).
In the same way as strength training, balance training when followed as a single intervention revealed no evidence to be effective in reducing the rate of falls and the risk of falling (23), yet the inclusion of balance training in exercise programs appeared to be a crucial factor in reducing falls (23, 27, 35, 37). Additionally, it is recommended that exercises must provide a moderate or high challenge to balance in order to prevent falls (37). Hence, this explained that different exercise programs that included balance training were similarly effective in reducing falls (35, 75, 76). According to one RCT in our review, a higher effect of balance intervention in reducing falls can be found in studies that are of a single-center nature (42). A previous study found that balance training on a foam rubber affected postural reflex in older adults (77) through improvement in the proprioception and sensitivity of lower limbs and cutaneous receptors in the soles (78). An interesting result in our review is that both foam rubber and stable surface interventions improved lower extremity muscle strength in addition to balance, with no significant difference between both (43). This is consistent with other studies that reported improvement in muscle strength after balance interventions (33, 34, 36). Other studies found a relationship between single-leg standing similar to the intervention in this trial and muscle activation (79, 80). This would prove that the progressive step marching exercise in our review is able to improve lower limb strength and eventually reduce the rate of falls in older adults (62). On the contrary, one trial we investigated did not reveal significant improvement in leg strength outcomes at the end of the balance intervention compared with pre-intervention, however, it was significant when compared to a combined intervention of virtual balance and static and dynamic balance exercises (60).
Perturbation-based balance exercises showed improvement in local dynamic stability and balance recovery with effects lasting for a week after the intervention, though it was a one-session intervention (47), others showed a reduction in the rate of all falls and slip falls (57). This is in agreement with other studies that showed quick effects (81, 82) and long-lasting ones with marginal reduction in gains (83, 84). Other trials of perturbation training in this review with longer intervention exhibited significant improvement in balance confidence using the ABC scale, dynamic stability, balance ability, and functional capacity compared to control, even more effective than traditional balance training (50, 53). Mean scores on the ABC scale improved from 65 to 80. One study revealed that the ABC scale is a strong predictor of falls in older adults, with those with a score < 67 having a high probability to fall (82). Others reported improvement in balance confidence after 4 weeks of perturbation training (85).
The multi-component intervention included a combination of trunk stability exercises and stretching (63), demonstrating significant improvement in complex walking ability. Combined strength and aerobic exercise interventions led to enhancement of lower limb strength (58), and improvement in aerobic capacity (63). In a study, it was found that improvements in balance and mobility persisted for up to 1 year after participating in a-32 week combined resistance and flexibility training program (86). Others reported that multi-component interventions had positive effects on the rate of falls (23, 27, 87, 88) and the risk of falling (23, 27) in addition to improvements in strength and balance outcomes (87, 88). Multiple categories of exercise programs containing balance training and muscle strengthening demonstrated their effectiveness in reducing both rate of falls and the risk of falling (23), whereas for others, balance and functional exercises plus strengthening revealed the same effectiveness (27). A previous study of combined strengthening and balance interventions found that physical performance was maintained during the follow-up, and that medically-attended injurious falls were significantly less after 5 years, while gains diminished in strengthening-only or balance-only interventions (89). It has been recommended that exercises for fall prevention must be of sufficient doses (i.e., at least 2 h a week) as well as in an ongoing manner (37).
Chronic diseases and multimorbidity (i.e., the coexistence of ≥2 chronic diseases in the same person) are prevalent among adults over the age of 65 years (90–93), and studies found that coronary artery diseases, stroke, diabetes, and arthritis are associated with physical inactivity in the older population (94, 95). However, participating in physical activity is believed to prevent and reduce the number of chronic diseases in older adults. (96). Others reported that the risks of falls and recurrent falling are directly proportional to the number of chronic diseases (97, 98). Frailty (99) and polypharmacy (100) (i.e., taking ≥2 drugs) are possible explanations for the connections with multimorbidity.
When studying the multimorbidity patterns (i.e., the classification of chronic diseases into different combinations based on the associations between them), the increased risk of falls was higher in the visceral-arthritic and mental-sensory patterns (97), while recurrent falling was significantly associated with a cluster of the highest prevalence of osteoporosis and a cluster that had the highest number of chronic conditions (98).
Therefore, practicing regular physical activity is crucial in reducing and preventing chronic diseases, maintaining a healthy musculoskeletal system and balance, and reducing the risk of falling.
A major strength of our review is that, to our knowledge, it is the first systematic review of RCTs to investigate the effects of different exercise interventions on ambulatory community-dwelling older adults. This study has several limitations that need to be taken into consideration. First, this review was limited to older adults who were free of dementia, stroke, Parkinson’s disease, multiple sclerosis, or recent fractures, therefore findings cannot be generalized to higher-risk populations. Second, trials with home exercise programs and virtual reality exercises were excluded. Third, the review results can only be generalized to home-dwelling older adults; trials with institutionalized older adults were excluded as well. Fourth, performing a meta-analysis was not possible due to the heterogeneity available in the included studies; variabilities in outcomes and interventions that obviously appear in prior sections of the current review. Therefore, as an alternative to a meta-analysis, we used other methods to compare the effects among the included studies. Finally, there is a lack of RCTs that particularly consider older adults with limited access to health care or in low-income countries.
5. Conclusion
In conclusion, our review addressed numerous RCTs of physical exercises composed of strengthening, balance, or multi-component interventions on physical functionality and risk of falls in community-dwelling older adults. The present review confirms the previous findings that physical exercise improves the components of functional ability, i.e., lower extremity strength, balance, and mobility. Additionally, physical exercise reduces falls and minimizes their serious sequelae. Further research on fall prevention is required that specifically considers high-risk older adults, low-income countries, and older adults in vulnerable contexts with limited access to health care.
