Impact of Tailored Multicomponent Exercise for Preventing Weakness and Falls on Nursing Home Residents’ Functional Capacity

ObjectivesWe aimed to determine whether the benefits of long (24 weeks) and short (4 weeks) training programs persisted after short (6 weeks) and long (14 weeks) periods of inactivity in older adult nursing home residents with sarcopenia.DesignMulticenter randomized trial.InterventionThe Vivifrail tailored, multicomponent exercise program (http://vivifrail.com) was conducted to individually prescribe exercise for frail older adults, depending on their functional capacity. The training included 4 levels combining strength and power, balance, flexibility, and cardiovascular endurance exercises.Setting and ParticipantsTwenty-four institutionalized older adults (87.1 ± 7.1 years, 58.3% women) diagnosed with sarcopenia were allocated into 2 groups: the Long Training-Short Detraining (LT-SD) group completed 24 weeks of supervised Vivifrail training followed by 6 weeks of detraining; the Short Training-Long Detraining (ST-LD) group completed 4 weeks of training and 14 weeks of detraining.MeasuresChanges in functional capacity and strength were evaluated at baseline, and after short and long training and detraining periods.ResultsBenefits after short and long exercise interventions persisted when compared with baseline. Vivifrail training was highly effective in the short term (4 weeks) in increasing functional and strength performance (effect size = 0.32-1.44, P < .044) with the exception of handgrip strength. Continued training during 24 weeks produced 10% to 20% additional improvements (P < .036). Frailty status was reversed in 36% of participants, with 59% achieving high self-autonomy. Detraining resulted in a 10% to 25% loss of strength and functional capacity even after 24 weeks of training (effects size = 0.24-0.92, P < .039).Conclusions and ImplicationsIntermittent strategies such as 4 weeks of supervised exercise 3 times yearly with no more than 14 weeks of inactivity between exercise periods appears as an efficient solution to the global challenge of maintaining functional capacity and can even reverse frailty in vulnerable institutionalized older adults.     

Managing sarcopenia with progressive resistance exercise training

Advancing age appears to alter the chemical and physical properties of skeletal muscle proteins. Alterations include: reduced contractile, mitochondrial, and enzyme protein synthesis rates, altered expression and post-translational modifications to muscle proteins, reduced maximum voluntary muscle strength, reduced muscle strength per unit muscle mass and muscle power. These age-associated impairments in muscle protein quantity and quality contribute to physical disability and frailty, a loss of independent function, the risk of falling and fractures, and contribute to escalating health care costs. Progressive resistance exercise training is a potent, non-pharmacologic, effective therapy that opposes the impairments in muscle protein quantity and quality in middle age and physically frail adults. In the absence of contraindications to exercise, muscle proteins adapt to an exercise training stimulus despite the depredation of age. The proposed pathogenesis for some of these impairments is briefly reviewed. Evidence that supports the use of progressive resistance exercise training to restore muscle quality and quantity in elderly adults is reviewed.     

Comparison of the effects of a home-based and group-based resistance training program on functional ability in older adults

PURPOSE: To compare the effectiveness of home- and group-based, progressive resistance training programs and a group walking program in improving functional performance in older adults. DESIGN: A quasi-experimental trial, in which retirement villages were assigned to one of three groups: home-based resistance training, group-based resistance training, and group-based walking. SUBJECTS: One hundred sixty-seven retirement village residents aged 65 to 96 years. INTERVENTION: Nine resistance training exercises, using graded exercise bands and body weight, two balance exercises, and 10 stretches. Home-based participants were given an exercise booklet, 8 hours of instruction, and telephone support. Instructors supervised the group-based resistance training and walking programs. Each group exercised twice weekly for 20 weeks. MEASURES: Functional performance (strength, aerobic endurance, flexibility, and agility/ dynamic balance) was assessed using the Senior Fitness Test. ANALYSIS: Intervention effects were evaluated using mixed-model, repeated measures analysis of variance. RESULTS: Significant between-group differences were observed only for the lower-body flexibility test. Group resistance training participants improved, but home resistance training and walking participants did not. However, strength, lower-body flexibility, and agility/dynamic balance improved in the group-based resistance training participants, and strength and upper-body flexibility improved in the home-based participants. No improvements were observed in the walking group. CONCLUSION: Findings support the implementation of both home- and group-based resistance training programs in retirement villages. Encouraging residents to adopt and maintain a resistance training program remains a research priority.     

Time Effects on Physical Performance in Older Adults in Nursing Home: A Narrative Review

Objectives

To gather available evidence about overtime changes on physical performance in institutionalized elderly.

Design, setting and participants

An electronic search was performed on PubMed database on May 2018. We selected articles reporting the evolution of physical performance in older adults living in care institutions. We looked for data from observational longitudinal studies; data from clinical trials were extracted only for subjects who did not receive exercise intervention. All types of performance-based tests, for upper- and/or lower-body, were scrutinized.

Results

Seventeen studies were reviewed; mean age varied from 78.3 to 88 years old. Fourteen studies were randomized controlled trials (RCTs), other three studies were non-randomized trials and a longitudinal observational study. Different tests assessing physical performance were examined: upper limb strength and lower limb strength, static balance, dynamic balance and mobility showed a tendency to decline over time. On average hand grip strength decreased by 2.2% per month, chair stand test by 3.5%, Berg balance scale by 2%, timed up-and-go test by 2.8%, gait speed by 2.1% and short physical performance battery by 2.8%. A minority of studies have shown an improvement in lower limb muscle strength, endurance and gait speed: in these studies, participants did not attend any kind of physical training but took part to social activities or cognitive interventions.

Conclusion

This review shows how physical performance decreases over time in nursing home residents and quantifies their decline. However, in active controls, there was an improvement in some physical performance measures, which indicates that intervention other than exercise might prevent some loss in physical performance.

     

Physical Exercise Improves Function in Acutely Hospitalized Older Patients: Secondary Analysis of a Randomized Clinical Trial

ObjectivesTo evaluate the effects of an exercise intervention on physical function, maximal muscle strength, and muscle power in very old hospitalized patients.DesignIn a randomized controlled trial, 130 hospitalized patients were allocated to an exercise intervention (n = 65) or a control group (n = 65). The intervention consisted of a multicomponent exercise training program performed during 5-7 consecutive days (2 sessions/d). The usual care group received habitual hospital care, which included physical rehabilitation when needed.Setting and participantsAcute care for elderly unit. Older adults age >75 years.MeasuresPhysical function, assessed with the Short Physical Performance Battery test and the Gait Velocity Test (GVT), were the primary endpoints. The GVT was also administered under dual-task conditions (ie, verbal and arithmetic GVT). The functional tasks were recorded using an inertial sensor unit to determine the movement pattern. The secondary endpoints were maximal muscle strength and muscle power output.ResultsThe exercise intervention program provided significant benefits over usual care. At discharge (primary time point), the exercise group showed a mean increase of 1.7 points in the Short Physical Performance Battery scale (95% confidence interval [CI] 0.98, 2.42) and 0.14 m·s-1 in the GVT (95% CI 0.086, 0.194) over the usual care group. The intervention also improved the verbal (0.151; 95% CI 0.119, 0.184 vs ?0.001; 95% CI –0.025, 0.033 in the control group) and arithmetic GVT (0.115; 95% CI 0.077, 0.153 vs ?0.004; 95% CI –0.044, 0.035). Significant benefits were also observed in the intervention group in movement pattern, as well as in muscle strength and muscle power.Conclusions and implicationsAn individualized multicomponent exercise training program improves physical function, maximal muscle strength, and muscle power in acutely hospitalized older patients. These findings support the importance of physical exercise for avoiding the loss of physical functional capacity that frequently occurs during hospitalization in older adults.     

Protein Supplementation Increases Muscle Mass Gain During Prolonged Resistance-Type Exercise Training in Frail Elderly People: A Randomized,Double-Blind,Placebo-Controlled Trial

ObjectivesProtein supplementation has been proposed as an effective dietary strategy to augment the skeletal muscle adaptive response to prolonged resistance-type exercise training in elderly people. Our objective was to assess the impact of protein supplementation on muscle mass, strength, and physical performance during prolonged resistance-type exercise training in frail elderly men and women.Design/setting/participantsA randomized, double-blind, placebo-controlled trial with 2 arms in parallel among 62 frail elderly subjects (78 ± 1 year). These elderly subjects participated in a progressive resistance-type exercise training program (2 sessions per week for 24 weeks) during which they were supplemented twice daily with either protein (2 1 15 g) or a placebo.MeasurementsLean body mass (DXA), strength (1-RM), and physical performance (SPPB) were assessed at baseline, and after 12 and 24 weeks of intervention.ResultsLean body mass increased from 47.2 kg (95% CI, 43.5–50.9) to 48.5 kg (95% CI, 44.8–52.1) in the protein group and did not change in the placebo group (from 45.7 kg, 95% CI, 42.1–49.2 to 45.4 kg, 95% CI, 41.8–48.9) following the intervention (P value for treatment × time interaction = .006). Strength and physical performance improved significantly in both groups (P = .000) with no interaction effect of dietary protein supplementation.ConclusionsProlonged resistance-type exercise training represents an effective strategy to improve strength and physical performance in frail elderly people. Dietary protein supplementation is required to allow muscle mass gain during exercise training in frail elderly people. Trial Registration: clinicaltrials.gov identifier: NCT01110369.     

Management of Sarcopenia: A Network Meta-Analysis of Randomized Controlled Trials

ObjectiveThis study aimed to determine the comparative effectiveness of interventions in treatment of sarcopenia. The primary outcome was the measure of treatment effect on muscle mass, and secondary outcomes were the treatment effect on muscle strength and physical performance.DesignSystematic review and network meta-analysis (NMA).Setting and ParticipantsParticipants with sarcopenia receiving interventions targeting sarcopenia in any setting.MethodsData sources: Relevant RCTs were identified by a systematic search of several electronic databases, including CINAHL, Embase, MEDLINE, and the Cochrane Central Registry of Controlled Trials (CENTRAL) from January 1995 to July 2019. Duplicate title and abstract and full-text screening, data extraction, and risk of bias assessment were performed.Data extraction: All RCTs examining sarcopenia interventions [mixed exercise (combined aerobic and resistance exercise), aerobic exercise, resistance exercise, balance exercise, physical activity and protein or nutrition supplementation, acupuncture, whole-body vibration, protein supplement or interventions to increase protein intake, any nutritional intervention other than protein, and pharmacotherapy] were included. Comparators were standard care, placebo, or another intervention.Data synthesis: We performed Bayesian NMA; continuous outcome data were pooled using the standardized mean difference effect size. Interventions were ranked using the surface under the cumulative ranking curve (SUCRA) for each outcome.ResultsA total of 59 RCTs were included after screening of 4315 citations and 313 full-text articles. Network meta-analysis of muscle mass outcome (including 46 RCTs, 3649 participants, 11 interventions) suggested that mixed exercise were the most effective intervention (SUCRA = 93.94%) to increase muscle mass. Physical activity and protein or nutrition supplementation, and aerobic exercise were the most effective interventions to improve muscle strength and physical performance, respectively. Overall, mixed exercise is the most effective intervention in increasing muscle mass and was one of the 3 most effective interventions in increasing muscle strength and physical performance.Conclusions and ImplicationsMixed exercise and physical activity with nutritional supplementation are the most effective sarcopenia interventions. Most of the included studies have a high risk of bias. More robust RCTs are needed to increase the confidence of our NMA results and the quality of evidence.     

Effectiveness of a Diet and Resistance Exercise Intervention on Muscle Health in Older Adults: ProMuscle in Practice

ObjectivesClinical studies show that resistance exercise and a protein-rich diet can counteract the age-related decline of muscle mass, strength, and physical performance. The aim of the ProMuscle in Practice study was to test effectiveness of a resistance exercise and dietary protein intervention for older adults implemented in a real-life setting.DesignA randomized controlled multicenter intervention study.Setting and ParticipantsOne hundred sixty-eight community-dwelling older adults were included (age 75 ± 6 years). A 12-week intensive support intervention including progressive resistance exercise supervised by a physiotherapist and dietitian guidance on increasing protein intake was followed by a voluntary 12-week moderate support intervention to continue the adapted lifestyle pattern. The control group received no intervention.MethodsCompliance was measured through attendance lists and 3-day food records. Physical functioning, leg strength (3-repetition maximum, knee extension strength), lean body mass [(LBM) dual-energy X-ray absorptiometry], and quality of life (5-level EQ-5D) were measured at baseline, and after 12 and 24 weeks. Differences in change between groups were assessed with linear mixed model analysis.ResultsThe intervention group increased protein intake and attended 83.6% of the training sessions. Short Physical Performance Battery score slightly increased in intervention participants [from 10.1 (95% confidence interval 9.7–10.5) to 10.4 (10.0–10.8) at week 12 and 10.6 (10.2–10.9) at week 24], where control participants decreased (time × treatment interactions, P < .05). Improvements in intervention group compared with controls were also observed for Timed Up-and-Go, strength and LBM at both time points (time × treatment interactions, P < .05). No difference between groups was found for the 6-Minute Walking Test, activities of daily living, and quality of life.Conclusions and ImplicationsProMuscle in Practice was effective on improving muscle strength and LBM, with small changes in the composite function score in community-dwelling older adults in a real-life setting. Further research should explore feasibility of real-life implementation, as well as improving long-term compliance.     

The utility of resistance exercise training and amino acid supplementation for reversing age-associated decrements in muscle protein mass and function

Advancing age is associated with reduced skeletal muscle protein synthesis, altered expression of and chemical modifications to muscle proteins, reduced muscle strength, muscle strength per unit muscle mass and muscle power (sarcopenia). These age-associated impairments in the quantity and quality of contractile protein contribute to physical disability and frailty, a loss of independent function, the risk of falling and fractures, and escalating health-care costs. Progressive resistance exercise training is a potent, non-pharmacologic, efficacious therapy for the impairment in muscle quantity and quality in middle age and physically frail adults. Evidence is accumulating that dietary amino acid supplementation may also improve muscle protein balance in the elderly. Several potential cellular mechanisms for the loss of muscle protein and resistance exercise-induced improvements in muscle quantity and quality in elderly adults are reviewed.     

Minerals and Sarcopenia in Older Adults: An Updated Systematic Review

ObjectiveThis systematic review aims to reevaluate the role of minerals on muscle mass, muscle strength, physical performance, and the prevalence of sarcopenia in community-dwelling and institutionalized older adults.DesignSystematic review.Setting and ParticipantsIn March 2022, a systematic search was performed in PubMed, Scopus, and Web of Sciences using predefined search terms. Original studies on dietary mineral intake or mineral serum blood concentrations on muscle mass, muscle strength, and physical performance or the prevalence of sarcopenia in older adults (average age ≥65 years) were included.MethodsEligibility screening and data extraction was performed by 2 independent reviewers. Quality assessment was performed with the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies. Risk of bias was evaluated using the Risk Of Bias In Non-randomized Studies-of Exposure (ROBINS-E) tool.ResultsFrom the 15,622 identified articles, a total of 45 studies were included in the review, mainly being cross-sectional and observational studies. Moderate quality of evidence showed that selenium (n = 8) and magnesium (n = 7) were significantly associated with muscle mass, strength, and physical performance as well as the prevalence of sarcopenia. For calcium and zinc, no association could be found. For potassium, iron, sodium, and phosphorus, the association with sarcopenic outcomes remains unclear as not enough studies could be included or were nonconclusive (low quality of evidence).Conclusions and ImplicationsThis systematic review shows a potential role for selenium and magnesium on the prevention and treatment of sarcopenia in older adults. More randomized controlled trials are warranted to determine the impact of minerals on sarcopenia in older adults.     

Two-Year Follow-up of a Multimodal Intervention on Functional Capacity and Muscle Power in Frail Patients With Type 2 Diabetes

ObjectivesTo analyze the effects of a program composed of resistance training and nutritional interventions on functional capacity, maximal strength, and power output after 2 years of follow-up, including 2 periods of 16 weeks of intervention followed by several weeks of intervention cessation in frail patients with type 2 diabetes.DesignMIDPOW is a substudy of a multicenter, multimodal intervention composed of resistance training combined with a structured diabetes and nutritional education program in frail and prefrail older people with type 2 diabetes (MID-Frail).Setting and ParticipantsThis study recruited 52 participants (mean age: 79 ± 5.6, 63% women), with type 2 diabetes mellitus, frail or prefrail using Fried's frailty phenotype.MethodsPrimary outcomes of this substudy were Short Physical Performance Battery (SPPB) and maximal power output at 30% and 80% of 1RM.ResultsEach set of 16 weeks of intervention resulted in significant improvements in SPPB performance by a mean of 36.1% at week 18 (P < .001) and 10.2% at week 68 (P < .05). Maximal power output improvements at 30% and 80% of the 1RM ranged from 45.2% to 57.2% at week 18 (P < .01–.001); and no significant changes were observed after the second period of intervention. After 2 years of follow-up, the SPPB and maximal power values observed remained significantly higher than the baseline.Conclusions and ImplicationsResistance training combined with nutritional program improved SPPB, maximal strength, and power output in older frail patients with diabetes. These improvements were maintained above the basal levels after several weeks of intervention cessation during a 2-year follow-up.     

High-Intensity Interval and Resistance Training Improve Health Outcomes in Older Adults With Coronary Disease

ObjectiveBoth high-intensity interval training (HIIT) and resistance exercises (R) are used in cardiac rehabilitation in patients with coronary artery disease (CAD). However, the combined effect of an HIIT + R exercise program in older adults with CAD is not well investigated. The study's purpose was to assess the changes in anthropometric parameters, physical activity, functional capacity, physiological parameters, and quality of life (QoL) in this population following a combined HIIT + R program.DesignThe study was a 2-group (n = 45 each) randomized controlled single-blinded trial.Setting and ParticipantsThe study was done at a treatment clinic of a tertiary hospital. The mean age of participants was 69.23 ± 4.9 years. The HIIT + R group performed 8 sessions (1/wk) of HIIT + R training. The 30 minutes of the active exercise phase consisted of ten 3-minute bouts. Each bout comprised of 1 minute of high-intensity treadmill walking at 85% to 90% maximum heart rate (MHR), followed by a low-intensity walking at 60%-70% MHR, followed by low-to moderate-intensity resistance training. The Usual Care group underwent conventional medical treatment.MeasuresAnthropometric measurements [weight, body mass index (BMI), waist circumference, body fat percentage, lean body mass], physical activity (International Physical Activity Questionnaire), functional capacity (Incremental Shuttle Walking Test), physiologic measurements (blood pressure, heart rate), and QoL (36-Item Short Form Health Survey) were measured pre- and postintervention.ResultsSignificant group and time interaction were found for the participants in the HIIT + R Group for BMI (P = .001), body fat percentage (P = .001), waist circumference (P < .001), physical activity (P < .001), functional capacity (P < .001), and QoL (P = .001) compared with the UC Group. Significant improvement in systolic blood pressure (P = .001) was seen in the HIIT + R group.Conclusions and ImplicationsA combined HIIT + R training protocol in older adults with CAD can be useful in producing desired health outcomes. Further evaluation of longer duration exercise programs with more frequent dosing needs to be evaluated for their benefits and sustainability.     

Effects of short-term exercise training on signs and symptoms of generalized anxiety disorder

BackgroundNo randomized controlled trial has investigated exercise training effects on signs and symptoms that characterize patients with Generalized Anxiety Disorder (GAD).ObjectivesTo quantify and compare the effects of six weeks of resistance (RET) and aerobic exercise training (AET) on signs and symptoms associated with GAD.MethodsThirty sedentary women, aged 18–37 years, diagnosed by blinded clinicians with a primary DSM-IV diagnosis of GAD, who were not engaged in treatment other than pharmacotherapy, were randomized to six weeks of RET, AET, or wait list (WL). RET involved two weekly sessions of lower-body weightlifting. AET involved two weekly sessions of leg cycling matched with RET on body region, positive work, exercise time, and load progression. Outcomes included concentration difficulty, trait anxiety, symptoms of depression, tension, low vigor, fatigue and confusion, irritability, muscle tension, and pain location and intensity. Hedges’ d effect sizes and 95% confidence intervals were calculated at weeks two, four, and six for each exercise condition compared to WL.ResultsRET significantly reduced feelings of anxiety-tension and the frequency and intensity of irritability. RET also resulted in six-week Hedges’ d effect sizes ≥0.36 for trait anxiety, concentration, symptoms of depression, fatigue and vigor, and pain intensity. AET resulted in comparable improvements in trait anxiety, concentration, irritability, muscle tension, and symptoms of fatigue and vigor. Effects for 9 of 12 outcomes were non-significantly larger for RET compared to AET.ConclusionsShort-term RET and AET provoke comparable improvements in signs and symptoms associated with GAD, particularly irritability, anxiety, low vigor and pain. Findings warrant further investigation.Clinical trial registration(ClinicalTrials.gov) Identifier: NCT00953654.     

Four-Month Course of Soluble Milk Proteins Interacts With Exercise to Improve Muscle Strength and Delay Fatigue in Elderly Participants

BackgroundThe benefit of protein supplementation on the adaptive response of muscle to exercise training in older people is controversial.ObjectiveTo investigate the independent and combined effects of a multicomponent exercise program with and without a milk-based nutritional supplement on muscle strength and mass, lower-extremity fatigue, and metabolic markers.DesignA sample of 48 healthy sedentary men aged 60.8 ± 0.4 years were randomly assigned to a 16-week multicomponent exercise training program with a milk-based supplement containing, besides proteins [total milk proteins 4 or 10 g/day or soluble milk proteins rich in leucine (PRO) 10 g/day], carbohydrates and fat. Body composition, muscle mass and strength, and time to task failure, an index of muscle fatigue, were measured. Blood lipid, fibrinogen, creatine phosphokinase, glucose, insulin, C-reactive protein, interleukin-6, tumor necrosis factor-α soluble receptors, and endothelial markers were assessed.ResultsBody fat mass was reduced after the 4-month training program in groups receiving 10 g/day of protein supplementation (P < .01). The training program sustained with the daily 10 g/day PRO was associated with a significant increase in dominant fat free mass (+5.4%, P < .01) and in appendicular muscle mass (+4.5%, P < .01). Blood cholesterol was decreased in the trained group receiving 10 g/day PRO. The index of insulin resistance (homeostasis model assessment–insulin resistance) and blood creatine phosphokinase were reduced in the groups receiving 10 g/day PRO, irrespective of exercise. The inflammatory and endothelial markers were not different between the groups. Training caused a significant improvement (+10.6% to 19.4%, P < .01) in the maximal oxygen uptake. Increased maximum voluntary contraction force was seen in the trained groups receiving 10 g/day of proteins (about 3%, P < .05). Time to task failure was improved in the trained participants receiving a 10 g/day supplementation with PRO (P < .01).ConclusionsSoluble milk proteins rich in leucine improved time to muscle failure and increase in skeletal muscle mass and strength after prolonged multicomponent exercise training in healthy older men.     

Randomised Controlled Trial of Fish Oil Supplementation on Responsiveness to Resistance Exercise Training in Sarcopenic Older Women

This study aims to investigate the effects of fish oil supplementation on the muscle adaptive response to resistance exercise training, physical performance and serum levels of inflammatory cytokines in sarcopenic older women. A randomised, double-blind, placebo-controlled trial is performed with thirty-four sarcopenic women (2010 European Consensus of Sarcopenia), aged ≥ 65 years. The participants are allocated into the following two groups: Exercise and Fish Oil (EFO) and Exercise and Placebo (EP). Both groups undertook a resistance exercise programme over 14 weeks. All participants are instructed to ingest 4 g/day of food supplements; the EP group received sunflower oil capsules, and the EFO group, fish oil capsules. The cross-sectional area (CSA) of the quadriceps muscle is calculated using magnetic resonance imaging (MRI). The strength of the lower limbs is measured using isokinetic dynamometry. Both groups show improvements in CSA and strength after the intervention. Changes in EFO are significantly greater compared with EP for muscle strength (peak torque, 19.46 Nm and 5.74 Nm, respectively, p < 0.001). CSA increased after the intervention in both groups (EFO; 6.11% and EP; 2.91%), although there is no significant difference between the groups (p = 0.23). There are no significant intra-group, inter-group or time differences in any of the cytokines measured. The use of fish oil supplementation potentiates the neuromuscular response to the anabolic stimulus from training, increasing muscle strength and physical performance in sarcopenic older women.     

Effect of Community-Based Functional Aerobic Training on Motor Performance and Quality of Life of Children with Spastic Cerebral Palsy

BackgroundEfficacies of community-based exercise programmes have been well reported, but there is scarce information on the expediency of community-based rehabilitation in a society where many children with disabilities live in poorly resourced settings with extremely limited rehabilitative services. This study investigated the effects of community-based functional aerobic exercise (CBFAE) on gross motor function, walking distance, and quality of life of children with cerebral palsy (CP).MethodsQuasi-experimental design was used. Children with gross motor function classification system (GMFCS) levels I – II participated in eight weeks CBFAE training four times/week, 50 minutes/day at 40–80% maximum heart rate. Gross motor function (GMF), walking distance and quality of life were assessed pre and post CBFAE training.ResultsSignificant improvement was observed in GMF (Dstanding) (8.2%, P=.000), GMF (E-walking + running+ jumping (5.12%, P=.004), walking distance (6.09%, P=.009). Higher significant positive effects of CBFAE were observed in Social wellbeing and acceptance (107.10%, P=.000), and participation and physical health (105.04%, P=.005) by children parent proxy. Self-reported results showed that for CBFAE, significant positive improvements were higher in pain and impact of disability (67.93%, P=.049) and participation and physical health (60.00%, P=.042).ConclusionCBFAE training contributes majorly to improved standing, walking, jumping and running and self-esteem, quality of life of children with spastic CP. Clinicians and exercise therapists should essentially incorporate CBFAE training and activities into the management of children with CP for improved mobility and functional performances.

Strength Training and Light Physical Activity Reduces the Apnea-Hypopnea Index in Institutionalized Older Adults

ObjectivesTo determine the effect of 7 weeks of resistance training and walking on the apnea-hypopnea index (AHI) in institutionalized older adults compared with a usual care control group.DesignSecondary analysis of data from a randomized controlled trial.SettingTen nursing and 3 assisted living facilities in Arkansas.ParticipantsInstitutionalized older adults.InterventionsExercise group (EG) performed supervised resistance training to arm and hip extensors on 3 days a week with additional 2 days a week of light walking. Usual care group (UC) participated in the usual activities provided within their living facility.MeasurementsTwo nights of polysomnography before and following 7-week intervention.ResultsAdjusted means in the EG group showed a decrease in AHI from 20.2 (SD ±1.3) at baseline to 16.7 (SD ±0.9) at 7 weeks. Absolute strength gains were not associated with improved AHI.ConclusionSupervised resistance training and light walking reduced the severity of obstructive sleep apnea in institutionalized older adults.
