The effects of the Friendship Online Intervention Program on physical activity, substance abuse, psychosomatic symptoms, and well-being among at-risk youth.

INTRODUCTION: At-risk youth are those who are currently or potentially exposed to physical, mental, or emotional danger. The Friendship Online Intervention Program (FOIP) was created to encourage physical activity (PA) and reduce risky behavior among vocational secondary-school youth in Israel. We wanted to evaluate the effect of FOIP on PA, substance abuse, and psychological factors, including psychosomatic symptoms and well-being. METHODS: From October 2021 to June 2022, nonrandom sampling was employed to select at-risk youth from vocational secondary schools for participation in the FOIP. Before and after the intervention, questionnaires were administered to the intervention and control groups. The effects of FOIP were evaluated by univariate and multivariable analyses. RESULTS: The intervention (n = 103) and control (n = 77) groups showed similar levels of PA, cigarette smoking, and alcohol consumption at the beginning of the study. At follow-up, the intervention group showed a 57% increase in PA versus no change for the control group and decreased levels of smoking compared to the control group (p < .001). Similarly, in the intervention group, the number of psychosomatic symptoms decreased (effect size = 1.68) and life satisfaction increased (effect size = 0.86). Group assignment (intervention or control group) significantly predicted PA level, cigarette smoking, psychosomatic symptoms, and life satisfaction (adjusted R2 = .46, .20, .08, and .28, respectively) with participants in the intervention group showing more favorable results compared with the control group. CONCLUSIONS: FOIP was effective in increasing PA and decreasing risky behaviors among youth. FOIP may help at-risk youth build resilience and promote their physical and mental health.

The Influence of Yoga on the Cognitive Function of People Aged 60 Years and Older: A Systematic Review.

Context: With aging, cognition declines, leading to functional limitations and a loss of independence. Yoga is a particular kind of physical activity that can have a positive influence on cognition in older adults, because it aims to improve physical skills and to enhance the ability to focus and to neutralize external mental stimulation. Objective: The literature review intended to evaluate the effects of different types of yoga interventions and to examine which cognitive functions were affected by them for healthy people aged 60 years and older. Design: A search of the terms "yoga and cognition" and "yoga and cognitive function" was conducted using the PubMed and EBSCO databases. For inclusion, an article must have: (1) included healthy participants aged 60 and above, (2) been an intervention lasting between one week and six months, and (3) been an RCT. Three reviewers independently assessed each study. Setting: The Academic College at Wingate, Israel. Participants: Out of 503 articles, only five met the inclusion criteria, and had in total 461 participants, 128 men and 333 women, aged 60 years and older. Interventions: Interventions in the studies lasted between one and six months. Yoga methods included Hatha yoga, Trataka yoga, Iyengar yoga, and Himalayan Siddha yoga. Outcome Measures: Methods and tools applied in the studies were compared. The outcome measures examining cognitive functions included working memory, executive functions, visual memory and processing, focus and attention, and reaction time. Brain physiology outcomes were also screened. Results: An analysis of the type of yoga method was conducted and is presented in terms of the length and frequency of each intervention, the tests applied, and the effects of each intervention. In three articles, with a total of 293 subjects, the yoga intervention groups showed significant improvements in the ability to perform various cognitive functions as compared to the control groups. In two articles, with a total of 168 participants, no significant improvements were found for any of the groups, and none of the articles reported a decline. Conclusions: The studies differed in the type of yoga, length of the intervention, and type of cognitive-function assessments, making results inconclusive. Nevertheless, based on the examined randomized controlled trials (RCTs), overall yoga may offer benefits to cognitive function. However, a greater number of RCTs with a larger number of participants and rigorous research methods are required to support this recommendation.

Long-term outdoor recreation program for adults with intellectual disabilities: Feasibility and effects.

BACKGROUND: While people with intellectual disabilities tend to refrain from physical activity, outdoor physical activity programs increase motivation to engage in physical activity. METHOD: Eighty adults with intellectual disabilities participated in a 12-month outdoor physical activity program. Attendance was used to assess feasibility. Aerobic capacity (6-min walk test), lower extremity endurance (30-s chair stand), and mobility (timed up and go) were assessed at three-time points: before, during, and after the program. Six interviews were also conducted with six staff members and participants. RESULTS: The physical activity program was feasible, with all six groups completing the year-long activity. The six-minute walk and timed-up-and-go tests improved significantly. The qualitative analysis indicates the program's strengths (instructors' qualities and programs' social component) and weaknesses (dependency on weather and bureaucracy). CONCLUSION: Among adults with intellectual disabilities, a long-term outdoor physical activity program is feasible as a means for increasing aerobic capacity and improving mobility ability.

Predictors of Future Walking Speed: A 12-Month Monitoring Program.

The purpose of the current study was to identify significant predictors of walking speed (WS) among community-dwelling older adults, as it is one of the most representative measures of functioning in their daily lives. Seventy-seven (24 adult men, 26 adult women, and 27 older-adult women) community-dwelling older adults (73.7 ± 4.9 years) performed two assessments, over a 12-month period. Several physical, cognitive, and psychological tests were performed, as well as assessing the preferred WS. Multiple linear regression, stratified by gender, was used to identify significant predictors of future WS. For the adult men, walking and functional performances at the first assessment predicted 71.9%; for adult women, reaction time, walking, and balance performance predicted 64.4%; and, for the older-adult women, fast walking and reaction time predicted 48.2% of the variance of future WS. Clinicians should consider including different exercises for each group of older adults to evaluate and preserve functional abilities.

The effect of circuit resistance training, empagliflozin or "vegeterranean diet" on physical and metabolic function in older subjects with type 2 diabetes: a study protocol for a randomized control trial (CEV-65 trial).

BACKGROUND: Treatment of the older diabetic individual comprises a therapeutic challenge. Currently little scientific evidence exists depicting the best approach to type 2 diabetes treatment in this growing sub-population of patients. The purpose of this study is to assess the effects of a modified plant-based Mediterranean diet ("vegeterranean" diet), circuit resistance training (CRT) and empagliflozin, separately or in combination, on body composition and physical function in older subjects with type 2 diabetes. The rationale for this study is to assess three interventions associated with a negative energy/caloric balance (increased caloric use in exercise, caloric restriction in the "vegeterranean" diet and caloric wasting by glycosuria with empagliflozin), their interaction and effect on body composition and physical function. METHODS: One hundred and twenty men and women ≥65 years of age with type 2 diabetes, and low levels of physical activity will be randomized (1:1:1 manner, gender stratified) for 10 weeks to one of 3 parallel arms: CRT consisting of 3 home sessions/week; ad-libitum plant-based Mediterranean diet (limited consumption of eggs, dairy and fish, avoidance of red meat and poultry) or empagliflozin 10 mg/day. After 10 weeks CRT will be added to the empagliflozin and diet arms for an additional 10 weeks. Allocation concealment and blinding of primary outcome assessors will be implemented. Efficacy will be determined by assessment of lean body mass, body weight, frailty and functional status, sarcopenia, HbA1c and quality of life questionnaires. Safety will be evaluated by routine monitoring of adverse events. This study was approved by the Tel-Aviv Sourasky Medical Center Institutional Review Board. DISCUSSION: The combination and comparison of these diverse interventions to metabolic control may lead to better understanding of their mechanism of action with potential clinical implications in older individuals. Also, this study will provide evidence of the effectiveness of these interventions on delaying the progression from diabetes to sarcopenia and/or frailty. TRIAL REGISTRATION: ClinicalTrials.gov PRS: NCT03560375 . Last registration date (last update): 06/06/2018. The trial was a-priori registered before actual recruitment of subjects.

A Preliminary Study of Dual-Task Training Using Virtual Reality: Influence on Walking and Balance in Chronic Poststroke Survivors.

BACKGROUND: Stroke is a leading cause of death and disability in the Western world, and leads to impaired balance and mobility. OBJECTIVE: To investigate the feasibility of using a Virtual Reality-based dual task of an upper extremity while treadmill walking, to improve gait and functional balance performance of chronic poststroke survivors. METHODS: Twenty-two individuals chronic poststroke participated in the study, and were divided into 2 groups (each group performing an 8-session exercise program): 11 participated in dual-task walking (DTW), and the other 11 participated in single-task treadmill walking (TMW). The study was a randomized controlled trial, with assessors blinded to the participants' allocated group. Measurements were conducted at pretest, post-test, and follow-up. Outcome measures included: the 10-m walking test (10 mW), Timed Up and Go (TUG), the Functional Reach Test (FRT), the Lateral Reach Test Left/Right (LRT-L/R); the Activities-specific Balance Confidence (ABC) scale, and the Berg Balance Scale(BBS). RESULTS: Improvements were observed in balance variables: BBS, FRT, LRT-L/R, (P < .01) favoring the DTW group; in gait variables: 10 mW time, also favoring the DTW group (P < .05); and the ABC scale (P < .01). No changes for interaction were observed in the TUG. CONCLUSIONS: The results of this study demonstrate the potential of VR-based DTW to improve walking and balance in people after stroke; thus, it is suggested to combine training sessions that require the performance of multiple tasks at the same time.

Acute aerobic activity enhances response inhibition for less than 30min.

Acute exercise appears to facilitate certain aspects of cognitive processing. The possibility that exercise may lead to more efficient inhibitory processes is of particular interest, owing to the wide range of cognitive and motor functions that inhibition may underlie. The purpose of the present study was to examine the immediate and the delayed effect of acute aerobic exercise on response inhibition, motor planning, and eye-hand coordination in healthy active adults. Forty healthy and active participants (10 females) with a mean age of 51.88±8.46years performed the Go-NoGo test (response inhibition) and the Catch Game (motor planning and eye-hand coordination) before, immediately after, and following a 30-min recovery period in two conditions: a moderate-intensity aerobic session and a control session. In 2-way repeated measures ANOVAs (2 treatments×3 times) followed by contrast comparisons for post hoc analyses, significant pre-post interactions - indicating improvements immediately following exercise but not following the control condition - were observed in the Go-NoGo measures: Accuracy, Reaction Time, and Performance Index, but not in the Catch Game. In the post-follow-up interaction a deterioration was observed in Performance Index, and a trend of deterioration in Accuracy and Reaction Time. The conclusion was that a single session of moderate-intensity aerobic exercise facilitates response inhibition, but not motor planning or eye-hand coordination, in middle-aged healthy active adults. On the other hand, the improvement does not last 30min following a recovery period. Further studies are needed to examine the duration of the inhibitory control benefits and the accumulative effect of a series of acute exercise bouts, as well as to determine the brain networks and/or neurotransmitter systems most affected by the intervention.

Motor Imagery Practice for Enhancing Elevé Performance Among Professional Dancers: A Pilot Study.

OBJECTIVE: Elevé is a core dance movement requiring the greatest ankle plantarflexion (PF) range of motion (ROM). One possible way to enhance elevé performance is by using motor imagery practice (MIP). The aims of this pilot study were to investigate: 1) functional ankle PF maximal angles and ROM while performing elevé among professional dancers, 2) the effect of MIP on enhancing elevé performance, and 3) participants' views on the MIP intervention and its feasibility in a professional dance company setting. METHODS: Five professional dancers, mean age 31 yrs (SD 1.87), participated in a 2-week MIP intervention. Data on ankle PF maximal angles and ROM were collected pre- and post-intervention using 3-dimensional motion capture while performing repeat (10 repetitions) and static (10 sec) elevé. RESULTS: At baseline, ankle PF maximal angles were 169.20° (SD 2.81°) and 168.36° (2.23°) and ankle PF ROM were 40.21° (3.35°) and 35.94° (3.95°) for the repeat and static tasks, respectively. After the MIP intervention, ankle PF maximal angles were 170.28° (4.26°) and 170.74° (3.77°) and ankle PF ROM were 41.53° (2.33°) and 39.30° (2.30°) for the repeat and static tasks, respectively. Feasibility of MIP was established with 100% compliance and positive views were expressed by participants. CONCLUSION: The results suggest MIP holds potential as an adjunct training method for enhancing elevé performance among professional dancers.

Health Promotion with Long-Term Physical Activity Program for Adults with Autism Spectrum Disorder.

Individuals with autism spectrum disorder (ASD) are at higher risk for developing common chronic diseases. Engagement in physical activity (PA) can prevent health issues; however, people with ASD are known to engage in lower levels of PA in comparison to their peers. This study evaluated the effect of a long-term, 12-month PA intervention on the fitness and quality of life of adults with ASD. A quantitative approach was implemented to assess participants' fitness, functional ability, quality of life, and participation in a range of PA classes at three different time points. Qualitative data were collected via in-depth, semi-structured interviews with three participants with ASD and three staff members. A total of 34 adults with ASD (mean age 39.76 + 7.27) participated in the quantitative part of the study. Approximately 53% of the participants exhibited perseverance and conducted adequate PA each month. Significant improvements were found in one fitness component and two quality-of-life components. Factors revealed for the program's success were the individuals' free choice of the PA classes and supporting people and a budget that tailored the project. Policymakers who plan health promotion programs for adults with ASD should consider long-term PA programs, with freedom of choice among PA modalities and schedules.

Effects of integrated motor imagery practice on gait of individuals with chronic stroke: a half-crossover randomized study.

OBJECTIVES: To test the effects of a new motor imagery practice approach, in which motor and motivational contents were integrated in order to improve gait in subjects with chronic poststroke hemiparesis. DESIGN: A half-crossover study composed of 2 phases. In phase 1, subjects were randomly assigned to receive either the experimental or the control treatment. In phase 2, the subjects who had initially received the control treatment "crossed over" to receive the experimental intervention. SETTING: The experimental and the control intervention were delivered in the subjects' homes; assessments were performed in a hospital laboratory. PARTICIPANTS: Community-dwelling individuals (N=23) with chronic poststroke hemiparesis whose gait was impaired. INTERVENTIONS: The experimental intervention, called integrated motor imagery practice, consisted of imagery scripts aimed at improving home and community walking as well as fall-related self-efficacy. The control treatment consisted of executed exercises to improve the function of the involved upper extremity. MAIN OUTCOME MEASURES: In-home walking, indoor and outdoor community ambulation, and fall-related self-efficacy. These were assessed before and after the intervention as well as at a 2-week follow-up. RESULTS: In-home walking was significantly improved after application of the experimental intervention (P≤.003), but not after the control treatment (P≤.68). Community ambulation did not improve. Fall-related self-efficacy was slightly improved by the integrated motor imagery intervention; however, the findings were not unequivocal. CONCLUSIONS: Home delivery of integrated motor imagery practice was feasible and exerted a positive effect on walking in the home. However, it was ineffective for improving gait in public domains. We speculate that the addition of physical practice to imagery practice may be essential for achieving that end.

Psychological functioning and adherence to the recommended dose of physical activity in later life: results from a national health survey.

BACKGROUND: Official health organizations have established the dose of physical activity needed for preserving both physical and psychological health in old age. The objective of this study was to explore whether adherence to the recommended criterion of physical activity accounted for better psychological functioning in older adults in Israel. METHODS: A random sample of 1,663 (799 men) Israelis reported their physical activity routine, and based on official guidelines were divided into sufficiently active, insufficiently active, and inactive groups. The General Health Questionnaire (GHQ) was used for assessing mental health and the Mini-Mental State Examination (MMSE) for assessing cognitive functioning. RESULTS: Factor analysis performed on the GHQ yielded two factors - positive and negative. Logistic regressions for the GHQ factors and for the MMSE were conducted for explaining their variance, with demographic variables entered first, followed by health and then physical activity. The explained variance in the three steps was Cox and Snell R2 = 0.022, 0.023, 0.039 for the positive factor, 0.066, 0.093, 0.101 for the negative factor, and 0.204, 0.206, 0.209 for the MMSE. CONCLUSIONS: Adherence to the recommended dose of physical activity accounted for better psychological functioning beyond demographic and health variables; however, the additional explained variance was small. More specific guidelines of physical activity may elucidate a stronger relationship, but only randomized controlled trials can reveal cause-effect relationship between physical activity and psychological functioning. More studies are needed focusing on the positive factor of psychological functioning.

Prediction of standing height among Israeli older adults: results from a national survey.

BACKGROUND: An accurate measurement of full height while standing is sometimes not possible among older adults, in particular among the frail elderly. For such cases, the use of knee height (KH) and ulna bone length (UL) has been suggested for standing height estimation. Studies have shown that predictive equations of height were ethnic-specific. AIM: This study attempted to develop representative equations to predict standing height based on KH, UL and waist circumference (WC) for older adult Israeli women and men. SUBJECTS AND METHODS: A random sample of 1500 older adults (aged 74.48 ± 6.09 years old). Participants were interviewed in their homes and measurements of Standing height, KH, UL and WC were taken. A quadratic regression analysis, for each sex separately, was performed to predict standing height based on age, KH, UL and WC. RESULTS: The adjusted r (2) standing height prediction equations were 0.51 and 0.67 for women and men, respectively. CONCLUSIONS: The prediction of the standing height of frail elderly Israelis, by KH, UL, WC and age, may be an alternative method when actual standing height is difficult or not possible to measure.

Should knee extension strength testing be implemented as a screening test for identifying probable and confirmed sarcopenia in older T2DM patients?

BACKGROUND: The accelerated loss of muscle strength and mass observed in older type 2 diabetes mellitus (T2DM) patients due to the combined effects of diabetes and obesity, greatly increases their risk for sarcopenia. Early detection and treatment of probable and confirmed sarcopenia is paramount to delay mobility disability. Using low handgrip strength cut-off points for the initial identification of sarcopenia according to the new European Working Group on Sarcopenia in Older People (EWGSOP2) guidelines may mask the presence of sarcopenia. Relative knee extension strength cut-off points using a simple hand-held dynamometer can assist clinicians in the diagnosis of probable and confirmed sarcopenia by possibly reducing false negative results. METHODS: A cohort of one hundred T2DM older patients (60% women) (mean age 74.5 years) mostly obese community dwelling older adults were evaluated for body composition by Bioelectrical impedance analysis (BIA), yielding appendicular skeletal mass index (ASMI) results. Patients underwent handgrip strength (HGS) and knee extension strength (KES) tests as well as functional ability tests. Prevalence of probable and confirmed sarcopenia using HGS and KES cut-off points were calculated. Pearson correlations were performed to evaluate the relationship between ASMI and limbs strength. A regression analysis was conducted to examine which variables best predict ASMI values. A multivariate analysis of covariance was performed to assess the effect of independent variables on KES and HGS. RESULTS: Using cutoff points for low KES identified 24 patients with probable sarcopenia and two with confirmed sarcopenia. Conversely, using the EWGSOP2 cut off points for low HGS, identified only one patient with probable sarcopenia and none of the patients with confirmed sarcopenia. CONCLUSION: KES cut-off points using a simple hand-held dynamometer can assist in the identification of probable and confirmed sarcopenia using EWGSOP2 cut off points for low muscle mass in a population of older T2DM patients for further analysis and early treatment. This is notably true in patients possessing high body mass index (BMI) alongside normal ASMI and HGS, potentially reducing false positive sarcopenia screening results.

Arm-curl field test for older women: is it a measure of arm strength?

The facilitative effect of physical activity on age-related decline is well documented. Specifically, it has been found to reduce the risk of dependency. However, physical activity programs for older adults should be carefully designed so that improvements in all aspects of movement and physical capacities are achieved. This means that efficient fitness measurements should be made available for coaches and trainers. The arm-curl test is a common field test known for measuring the strength of upper extremities in older age. The objective of the current study was to determine to what extent this test indeed assesses arm strength as well as other fitness aspects such as arm muscle endurance or general endurance. Scores of the arm-curl test were compared with strength and endurance of elbow flexors measured by an isokinetic dynamometer and general endurance measured by a stress test in 48 independently functioning women (age 72.04 ± 6.28 yr). Significant correlations were indicated between the arm-curl scores and both isokinetic endurance (r = 0.452) and general endurance (r = 0.437); however, a very low nonsignificant correlation was found between the arm-curl and isokinetic maximal strength scores. Coaches must be aware of the fact that the repetitive arm-curl exercise contains a significant aerobic component and thus may contribute to aerobic fitness and arm muscle endurance but not necessarily to arm strength.

Correlates of Early-Stage Frailty-Sleep, Fitness, Oxidative Stress, and BMI.

Frailty reflects a decreased reserve in multiple systems resulting from cumulative decline. Frailty markers should be identified as early as possible to attenuate the loss of reserve. The aim of this study was to identify potentially modifiable correlates of frailty in relatively healthy older adults. Volunteers (n = 122) were recruited from local councils and, based on gender and age, were divided into one group of men aged 77.0 (±5.3), and two groups of women, aged 68.8 (±3.6) and aged 78.4 (±3.4). Frailty was assessed by a Frailty Index. The examined correlates were: physical activity, physical fitness (predicted peak VO2), sleep quality, oxidative stress (hydrogen peroxide-H2O2) and depression. Both groups of women had poor scores on physical fitness compared to women's norms. In order to examine the contribution of each of the potential correlates to explaining the variance of frailty, stepwise regressions were performed for each group separately. Based on the results, none of the suggested correlates significantly explained the variability of frailty in the men. In the younger-aged women, predicted peak VO2 and sleep quality explained 22.4% of the variability of frailty. In the older women, Body Mass Index (BMI), oxidative stress and sleep quality explained 34.9% of the variance. It is possible that increased aerobic fitness and interventions for improving sleep quality in older, seemingly healthy women will slow down the frailty process. Further research is needed to assess potential correlates of frailty, and to initiate suitable interventions to mitigate the signs of frailty at an early stage.

Does Photobiomodulation Therapy Enhance Maximal Muscle Strength and Muscle Recovery?

Photobiomodulation has been shown to improve tissue and cell functions. We evaluated the influence of photobiomodulation, using a B-Cure laser, on: 1) maximal performance, and 2) muscle recovery after resistance exercise. Two separate crossover randomized double-blinded placebo-controlled trials were conducted. Sixty healthy physical education students (28 men, 32 women), aged 20-35, were recruited (30 participants for each trial). Participants performed two interventions for each experiment, with real lasers (GaAlAs, 808 nm) on three quadricep locations in parallel (overall treatment energy of ~150J) or sham (placebo) treatment. In the first experiment muscle total work (TW) and peak torque (PT) were measured by an isokinetic dynamometer in five repetitions of knee extension, and in the second experiment muscle recovery was measured after the induction of muscle fatigue by evaluating TW and PT in five repetitions of knee extension. There were no differences between treatments (real or sham) regarding the TW (F(1,28) = 1.09, p = .31), or PT (F(1,29) = .056, p = .814). In addition, there was no effect of photobiomodulation on muscle recovery as measured by the TW (F(1,27) = .16, p = .69) or PT (F(1,29) = .056, p = .814). Applying photobiomodulation for 10 min immediately before exercise did not improve muscle function or muscle recovery after fatigue.

The Effect of Balance and Coordination Exercises on Quality of Life in Older Adults: A Mini-Review.

The ability to control balance during activities of daily living (ADL) is impaired in older adults as a result of deterioration in the sensory systems (i.e., vestibular, visual, somatosensory), the cognitive system (central nervous system), and the musculoskeletal system. Consequently, many older adults face a risk of falling during their ADL. In most cases, falls and related injuries impair the quality of life and result in physical limitations, anxiety, loss of confidence, and fear of falling. Among a variety of fall prevention interventions, adapted physical activity programs have been suggested for improving balance control during ADL. These programs challenge the sensory, cognitive, and musculoskeletal systems while addressing balance constraints such as orientation in space, changes in direction, and the speed or height of the center of mass during static and dynamic situations resembling ADL. The above-mentioned elements can be dealt with through a combination of balance and coordination exercises that challenge the postural control systems in multiple dimensions-including vertical and horizontal changes of the center of mass, standing on unstable surfaces with a reduced base of support, and changing body directions. Consequently, such exercises require environmental information-processing. The combination of dual-task, function-oriented challenges while controlling balance stimulates the sensory and neuromuscular control mechanisms. Among older adults, these programs have been found to improve static and dynamic stability, as well as a number of aspects in the quality of life. Recently, they have also been found to improve cognitive functions such as memory and spatial cognition.

The effect of a stability and coordination training programme on balance in older adults with cardiovascular disease: a randomised exploratory study.

BACKGROUND: Cardiovascular diseases are considered a leading factor in mortality and morbidity. The older adult population with cardiovascular diseases has a higher risk of falls as compared to a matched age healthy population. OBJECTIVE: To investigate the effect of stability and coordination training within a cardiac rehabilitation programme on fall risk in older adults with cardiovascular diseases enrolled in cardiac rehabilitation. METHODS: Twenty-six people with cardiovascular diseases (age 74±8) were divided randomly into intervention and control groups. The intervention group received 20 min of stability and coordination exercises as part of their 80 min cardiac rehabilitation programme, while the control group performed the traditional cardiac rehabilitation programme, twice a week, for 12 weeks. Balance assessment was based on three tests: the Timed Up and Go, Functional Reach and Balance Error Scoring System, which were measured twice before the intervention, once following the intervention and once four weeks after the termination of the intervention. A two-way analysis of variance (group × time) with repeated measures was performed to examine differences between groups and between assessments. RESULTS: Seventy per cent of participants in the intervention group adhered to the programme, with significant improvement post-intervention in the Timed Up and Go (p < .01) and the Balance Error Scoring System (p < .05) with no changes among the control group. DISCUSSION: Stability and coordination training alongside a traditional cardiac rehabilitation programme may improve static and dynamic balance, and muscle strength, skills that are considered major components in postural control. Clinicians who work in cardiac rehabilitation centres should consider including this training alongside the routine cardiac rehabilitation programme.

The Acute Effect of Exercise on Executive Function and Attention: Resistance Versus Aerobic Exercise.

Acute aerobic exercise was shown to enhance such cognitive functions as executive function (EF) and attention. Acute resistance exercise was also shown to enhance cognitive functions, however, only few studies directly compared these two exercise modalities. The aim of this study was to evaluate the acute effect of a typical moderate intensity resistance exercise session as compared to a typical moderate intensity aerobic session, on executive function and attention. A counterbalanced repeated measures experimental design was applied. Forty physical education students (21 women; 19 men, age = 25.7±2.84 years) were tested before and after three sessions: aerobic, resistance, and control. Each session consisted of 30 minutes of exercise or a rest. Executive function and attention were assessed by components of the computerized Stroop Catch game and Go-NoGo cognitive tests. A two-way ANOVA showed a greater increase in attention scores after the resistance sessions (p < .05) compared to the control condition. Attention scores in the aerobic sessions showed a trend toward improvement but did not reach statistical significance. Scores of EF significantly increased, both after the resistance session and the aerobic session (p < .05), but not after rest in the control condition. Our findings show that an acute session of resistance exercise increased both Attention and EF test scores, while an aerobic exercise session improved only the EF scores.

Home-based motor imagery training for gait rehabilitation of people with chronic poststroke hemiparesis.

OBJECTIVE: To test the feasibility and efficacy of a home-based motor imagery gait training program to improve walking performance of individuals with chronic poststroke hemiparesis. DESIGN: Nonrandomized controlled trial. SETTING: Local facility. PARTICIPANTS: Participants (N=17) were community-dwelling volunteers with hemiparesis caused by a unilateral stroke that occurred at least 3 months before the study. INTERVENTION: Participants received 15 minutes of supervised imagery gait training in their homes 3 days a week for 6 weeks. The intervention addressed gait impairments of the affected lower limb and task-specific gait training. Walking ability was evaluated by kinematics and functional scales twice before the intervention, 3 and 6 weeks after the intervention began, and at the 3-week follow-up. MAIN OUTCOME MEASURES: Spatiotemporal, kinematic, and functional walking measurements. RESULTS: Walking speed increased significantly by 40% after training, and the gains were largely maintained at the 3-week follow-up. The effect size of the intervention on walking speed was moderate (.64). There were significant increases in stride length, cadence, and single-support time of the affected lower limb, whereas double-support time was decreased. Improvements were also noted on the gait scale of the Tinetti Performance-Oriented Mobility Assessment as well as in functional gait. Sixty-five percent of the participants advanced 1 walking category in the Modified Functional Walking Categories Index. CONCLUSIONS: Although further study is recommended, the findings support the feasibility and justify the incorporation of home-based motor imagery exercises to improve walking skills for poststroke hemiparesis.
