Lifestyle integrated functional exercise for people with interstitial lung disease (iLiFE): A mixed-methods feasibility study

BACKGROUND

People with interstitial lung disease (ILD) present low levels of physical activity (PA) and spend most of their time at home, especially in advanced stages of the disease. The Lifestyle Integrated Functional Exercise for people with ILD (iLiFE) embedding PA in patients' daily routines was developed and implemented.

OBJECTIVES

This study aimed to explore the feasibility of iLiFE.

METHODS

A pre/post mixed-methods feasibility study was conducted. Feasibility of iLiFE was determined by participant recruitment/retention, adherence, feasibility of outcome measures and adverse events. Measures of PA, sedentary behaviour, balance, muscle strength, functional performance/capacity, exercise capacity, impact of the disease, symptoms (i.e., dyspnoea, anxiety, depression, fatigue and cough) and health-related quality of life were collected at baseline and post-intervention (12-weeks). Semi-structured interviews with participants were conducted in-person immediately after iLiFE. Interviews were audio-recorded, transcribed and analysed by deductive thematic analysis.

RESULTS

Ten participants (5♀, 77±3y; FVCpp 77.1 ± 4.4, DLCOpp 42.4 ± 6.6) were included, but only nine completed the study. Recruitment was challenging (30%) and retention high (90%). iLiFE was feasible, with excellent adherence (84.4%) and no adverse events. Missing data were associated with one dropout and non-compliance with the accelerometer (n = 1). Participants reported that iLiFE contributed to (re)gain control in their daily life, namely through improving their well-being, functional status and motivation. Weather, symptoms, physical impairments and lack of motivation were identified as threats to keep an active lifestyle.

CONCLUSIONS

iLiFE seems to be feasible, safe and meaningful for people with ILD. A randomised controlled trial is needed to strengthen these promising findings.

Physiological profile comparison between high intensity functional training, endurance and power athletes

INTRODUCTION

High intensity functional trainings (HIFT), a recent development of high intensity trainings, includes in the same training session components of endurance exercises, elements of Olympic weightlifting and powerlifting, gymnastics, plyometrics and calisthenics exercises. Therefore, subjects practicing this type of activity are supposed to show physiological features that represent a combination of both endurance and power athletes. The aim of this study was to compare the physiological profile of three groups of age-matched endurance, HIFT and power athletes.

METHODS

A total of 30 participants, 18 to 38-year-old men were enrolled in the study. Participants were divided in three groups: HIFT (n = 10), endurance (END, n = 10), and power (POW, weightlifters, n = 10) athletes. All were evaluated for anthropometric characteristics, VO_2peak, handgrip, lower limb maximal isometric and isokinetic strength, countermovement vertical jump and anaerobic power through a shuttle run test on the field.

RESULTS

VO_2peak/kg was higher in END and HIFT than POW athletes (p = 0.001 and p = 0.007, respectively), but there were no significant differences between the first two. POW and HIFT athletes showed significant greater strength at the handgrip, countermovement jump and leg extension/flexion tests than END athletes. HIFT athletes showed highest results at the dynamic isokinetic test, while there were no significant differences at the shuttle run test among groups.

CONCLUSIONS

As HIFT reach aerobic levels similar to END athletes and power and strength output similar to POW athletes, it appears that HIFT programs are effective to improve both endurance-related and power-related physical fitness components.

Acute effect of core stability and sensory-motor exercises on postural control during sitting and standing positions in young adults

Core stability exercises and exercises that stimulate sensory-motor information are recommended for the prevention of injuries and the maintenance and rehabilitation of deficits related to postural control (PC). However, the comparison of results between core stability and sensory-motor exercises in the literature is limited to sitting and standing positions.

OBJECTIVE

To determine the acute effect of core stability and sensory-motor exercises on PC during sitting and standing in young adults.

METHODS

A total of 39 participants, with a mean age of 23 years, were randomly divided into three groups (1) Core stability exercises; (2) Sensory-motor exercises; (3) Control. Each group performed a sequence of five specific exercises of core stability and sensory-motor exercises (except controls). PC was evaluated before and after exercise in the seated and the one-legged stance conditions using a force platform.

RESULTS

No significant difference was found for any variables of postural oscillation (P > 0.05) among the three groups studied. The magnitude of the effect of interventions in general was a small to moderate effect (d = 0.02/-0.48).

CONCLUSION

The findings show that acute intervention with core stability and sensory-motor exercises did not produce any significant effects (reduction of postural oscillation) on PC during sitting and standing positions in young adults.

Incidence, severity and perceived susceptibility of COVID-19 in the UK CrossFit population

BACKGROUND

Contemporary literature indicates that a higher body mass index (BMI) serves as a risk factor for metabolic disease and is also correlated with greater disease severity. Subsequently, it has been linked to increased COVID-19 severity. The purpose of the study was to investigate whether regular CrossFit™ participation was associated with lower BMI, decreased COVID-19 severity and susceptibility.

METHODS

A cross-sectional study was conducted on 1806 CrossFit™ (CF) participants. Participants were asked about their age (yrs), sex (male vs. female), ethnic group, body height (cm) and weight (kg). Body mass index (BMI, kg/m2) was computed and consistent with WHO (2018) criteria. Participants self-reported their training history, health and lifestyle history, nutritional customs, present training status and suspected levels of exposure to COVID-19. Once submitted the collected data were coded, cleaned and analysed.

RESULTS

The final model comprised of 1806 CF individuals from an online survey response rate of 2086. The participants age ranged from 18 to 65+ yrs. Self-reported mean body mass index (BMI: kg/m2) reported that < 1% were underweight, 41% were healthy, 46% overweight, 10% class I obese, 2% class II obese, and < 1% class III obese. A Kruskal-Wallis H test compared gender and self-reported probability of being infected with COVID-19 with significant differences between subgroups (x2 (4, N = 1739) = 10.86, p = 0.03). Analysis of BMI and perceived severity of COVID-19 revealed a difference however not, significant (x2 (4, N = 1739) = 9.46, p = 0.051). Results on BMI and perceived probability of COVID-19 infection revealed no significant difference (x2 (4, N = 1739) = 2.68, p = 0.61). A separate analysis on BMI and perceived COVID-19 susceptibility revealed no significant difference (x2 (4, N = 1740) = 6.02, p = 0.20).

CONCLUSIONS

The purpose of the study was to establish whether habitual CrossFit™ participation is associated with reduced BMI, and to further investigate whether habitual participation impacted perceptions of disease. Results of the study indicate that self-reported CrossFit™ participation during the first UK lockdown, measured in minutes of exercise was indicative of a lower BMI. This has been associated with greater host immunity to disease. A history of CrossFit™ participation was not shown to impact perceptions of disease. However, our sample population reported few changes to habitual exercise during lockdown which may be due to the 'community' and increased adherence associated with CrossFit™.

The influence of rotational movement exercise on the abdominal muscle thickness and trunk mobility - Randomized control trial

BACKGROUND

Trunk rotations are important functional movements which form the foundations of human motion pattern, especially in the functions of walking and running. They prevent the functional impairments and structural lesions resulting from axial overloading in static positions such as sitting.

OBJECTIVES

The aim of the study was to assess the influence of rotational movement training exercises on the abdominal muscle thickness and spinal mobility range.

STUDY DESIGN

Randomized controlled trial.

METHODS

The study involved 73 individuals aged 18-45. The subjects were randomly divided into two groups. The study group (TG) comprised 40 people who performed rotational movement exercises over the period of 4 weeks (16 training sessions). In the control group (CG) the training was not applied. Changes in the thickness of selected abdominal muscles on ultrasound imaging were evaluated, as well as trunk mobility, based on the trunk lateral flexion test.

RESULTS

The analysis of the obtained data has demonstrated a statistically significant increase in the thickness of the abdominal internal (IO) (p < 0.05) and external oblique muscles (EO) (p < 0.001) in the study group (TG) between measurements I and II, and measurements I and III. A similar increase in the thickness was found in the summation measurement of TrA + IO + EO. Bilateral increase in the trunk lateral flexion range in the frontal plane has also been noted.

CONCLUSIONS

Rotational movement training of the trunk leads to an increase in the thickness of the abdominal oblique muscles. Rotational movement exercise training increases trunk mobility in the frontal plane.

Effect of recreational beach tennis on ambulatory blood pressure and physical fitness in hypertensive individuals (BAH study): rationale and study protocol

BACKGROUND

Different physical activities are widely recommended as non-pharmacological therapies to reduce blood pressure. However, the effectiveness of exercise programs is associated with its continuity and regularity, and the long-term adherence to traditional exercise interventions is often low. Recreational sports emerge as an alternative, being more captivating and able to retain individuals for longer periods. Besides, sport interventions have demonstrated improvements in physical fitness components that are associated with a lower incidence of hypertension. However, no studies have investigated the effects of recreational sports on 24 h ambulatory blood pressure. The aim of the present study is to evaluate the effect of beach tennis training on ambulatory blood pressure and physical fitness in individuals with hypertension.

METHODS

This study will be a randomized, single-blinded, two-arm, parallel, and superiority trial. Forty-two participants aged 35-65 years with previous diagnosis of hypertension will be randomized to 12 weeks of beach tennis training group (two sessions per week lasting 45-60 min) or a non-exercising control group. Ambulatory (primary outcome) and office blood pressures, cardiorespiratory fitness, muscle strength/power and quality of life will be assessed at baseline and after the intervention period.

DISCUSSION

Our conceptual hypothesis is that beach tennis training will reduce ambulatory blood pressure and improve fitness parameters in middle-aged individuals with hypertension. The results of this trial are expected to provide evidences of efficacy of recreational beach tennis practice on blood pressure management and to support sport recommendations for clinical scenario in higher risk populations.

Influence of combined functional resistance and endurance exercise over 12 weeks on matrix metalloproteinase-2 serum concentration in persons with relapsing-remitting multiple sclerosis - a community-based randomized controlled trial

BACKGROUND

The relevance of regular moderate to intense exercise for ameliorating psychomotor symptoms in persons with multiple sclerosis (pwMS) is becoming increasingly evident. Over the last two decades, emerging evidence from clinical studies and animal models indicate immune regulatory mechanisms in both periphery and the central nervous system that may underlie these beneficial effects. The integrity of the blood-brain barrier as the main structural interface between periphery and brain seems to play an important role in MS. Reducing the secretion of proteolytic matrix metalloproteinases (MMP), i.e. MMP-2, as disruptors of blood-brain barrier integrity could have profound implications for MS.

METHODS

In this two-armed randomized controlled trial 64 participants with relapsing-remitting MS (RRMS) (EDSS 0-4.0) will be allocated to either an intervention group or a passive wait list control group. The intervention group will perform 60 min of combined functional resistance and endurance exercises 3x per week over a period of 12 weeks in a community-based and publicly available setting. Changes in serum concentration of MMP-2 will be the primary outcome. Secondary outcomes are numbers of immune cell subsets, soluble (anti-) inflammatory factors, physical capacity, cognitive performance, physical activity behavior, gait performance, and patient-reported outcomes. All outcome measures will be assessed at baseline and after week 12 with an additional blood sampling before, during and immediately after a single training session in week 6.

DISCUSSION

To our knowledge, this will be the first RCT to investigate both the acute and chronic effects of a community-based intense functional resistance and endurance exercise regimen in persons with RRMS. Combining analysis of biological and cognitive or psychological outcomes may provide a better understanding of the MS-specific symptomology.

Comprehensive functional exercises with patient education for the prevention of venous thrombosis after major gynecologic surgery: A randomized controlled study

OBJECTIVE

To explore the functional exercises of deep breathing and lower limb motions for the prevention of venous thrombosis in patients undergoing major surgery for gynecologic malignancy.

METHODS

All eligible patients admitted to the gynecologic oncology unit were randomized into the study and control groups. A comprehensive set of functional exercises was provided to the study group under the instruction and supervision of medical staff. All patients received pre- and postoperative educational material, followed by questionnaires about the patient's perception and satisfaction of the material, and all indicated prophylactic medications were administered.

RESULTS

In total, 132 patients were randomized, and 62 and 53 patients in the study and control groups, respectively, were included in the final analysis. Venous thrombosis, identified by symptoms and/or postoperative ultrasound, was found in 9 (17.0%) and 2 (3.2%) patients in the control and study groups, respectively, which was significantly different (p = 0.012), and most of these instances (9/11, 81.8%) were intramuscular vein thrombosis. The incidence of venous thromboembolism (VTE) was not significantly different (1 [1.9%] versus 1 [1.6%]) between the two groups. In the regression model, functional exercise was the only factor associated with venous thrombosis (odds ratio 0.170, 95% confidence interval 0.035-0.815, p = 0.032) adjusted with diagnosis and surgical parameters. The detailed educational material had improved the perception and satisfaction of patients about the prevention of VTE.

CONCLUSION

In a phase 3, single-center randomized controlled study, a comprehensive set of functional exercises combining deep breathing and lower limb motions would significantly decrease the risk of venous thrombosis in patients undergoing major surgery for gynecologic malignancy, especially the risk of intravascular thrombosis.

A descriptive analysis of shoulder muscle activities during individual stages of the Turkish Get-Up exercise

The Turkish Get-Up (TGU) is a complex and multi-planar exercise; the performer begins in a supine lying position, progresses toward upright standing through a series of 7 stages while holding a mass overhead in one hand, and returns to the original supine lying position through a reversal of the same 7 stages. A descriptive analysis of shoulder muscle activity during the TGU may provide insight toward its use in training and rehabilitation contexts. Our objectives were to: (1) describe the activity patterns from a subset of muscles that span the glenohumeral joint during individual stages of the TGU, and (2) interpret these patterns through comparisons between left- and right-side muscles, and between the up and down phases of the TGU. Twelve individuals with at least one-year experience performing the TGU were included in this study. Surface electromyographic (EMG) recordings were bilaterally obtained from 8 glenohumeral muscle groups while participants performed ten trials of the TGU with a kettlebell in their right hand. Instants representing the start and end of each TGU stage were identified from a synchronized video for each trial, and EMG activities for each muscle were integrated over the duration of each stage. Average integrated EMG and within-participant coefficients of variation were calculated. Overall, the greatest muscular demand occurred during the second (press to elbow support) and fifth (leg sweep) stages. Activities from muscles on the ipsilateral side to the kettlebell (right-side) were greater during stages when the contralateral upper limb did not contribute to supporting the body; however, contralateral (left-side) muscles were invoked during stages when the non-kettlebell-bearing forearm or hand contributed to supporting the body. The results suggest the importance of training both phases of the TGU to gain the most benefit from the exercise and highlights the asymmetric nature of the exercise, which may be particularly relevant for athletes engaged in activities with rotational demands.

Comparison of a group-delivered and individually delivered lifestyle-integrated functional exercise (LiFE) program in older persons: a randomized noninferiority trial

BACKGROUND

The Lifestyle-Integrated Functional Exercise (LiFE) program is effective in improving strength, balance, and physical activity (PA) while simultaneously reducing falls in older people by incorporating exercise activities in recurring daily tasks. However, implementing the original LiFE program includes substantial resource requirements. Therefore, as part of the LiFE-is-LiFE project, a group format (gLiFE) of the LiFE program has been developed, which will be tested regarding its noninferiority to the individually delivered LiFE in terms of PA-adjusted fall incidence and overall cost-effectiveness.

METHODS

In a multi-centre, single-blinded noninferiority trial, an envisaged sample of N = 300 participants (> 70 years; faller and/or confirmed falls risk; community-dwelling) will be randomized in either LiFE or gLiFE. Both groups will undergo the same strength and balance activities as well as PA promotion activities and habitualization strategies as described in the LiFE programme, however, based on different approaches of delivery: During the 6-month intervention phase, LiFE participants will receive seven home visits and two telephone calls; in gLiFE, the program will be delivered in seven group sessions and also two telephone calls. Main outcomes are a) fall incidence per PA and b) incremental cost-effectiveness ratio comparing costs and quality-adjusted life years between the two interventions. Secondary outcomes include PA behaviour, motor performance, health status, psychosocial status, program evaluation, and adherence. Measurements will be conducted at baseline, 6-month and 12-month follow-up; evaluation of intervention sessions and assessment of psychosocial variables related to execution and habitualization of LiFE activities will be made during the intervention period as well.

DISCUSSION

Compared to LiFE, we expect gLiFE to (a) reduce falls per PA by a similar rate; (b) be more cost-effective; (c) comparably enhance physical performance in terms of strength and balance as well as PA. By investigating the economic and societal benefit, this study will be of high practical relevance as noninferiority of gLiFE would facilitate large-scale implementation due to lower resource usage. This would result in better reach and increased accessibility, which is important for subjects with a history of falls and/or being at risk of falls.

The effect of functional stretching exercises on functional outcomes in spastic stroke patients: A randomized controlled clinical trial

BACKGROUND

Stroke is the biggest cause of disability in adults. Spasticity is a primary impairment of stroke with a highly variable prevalence. In the present research, we aimed to determine the impact of functional stretching exercises on functional outcomes in stroke patients.

METHODS

Thirty stroke patients were randomized into two groups-Experimental group and control group for the purposes of the study. The subjects in the experimental group participated in a functional stretching training program at the rehabilitation center thrice a week for four weeks. The subjects in both groups were evaluated in 3 intervals, once at baseline, once at the end of the program, and once at 2 months following the program. Clinical assessments, such as measuring spasticity, were conducted using the Modified Modified Ashworth Scale (MMAS). Functional outcomes were also evaluated, using the Timed Up and Go (TUG) test, as well as the Timed 10-Meter Walk Test (WTT). Friedman test in SPSS version 22.0 was used to analysis the response variables with respect to each stage of evaluation. Spearman rank correlation was also used to measure correlation among clinical assessments and functional outcomes.

RESULTS

The comparison between two groups showed significant differences only in the Modified Modified Ashworth Scale and Visual Analogue Scale (VAS) post treatment. The experimental group showed significant differences in the MMAS (p = 0.002), WTT (p < 0.001), and TUG (p < 0.001) scores. Nevertheless, the scores of the control group were not significantly different in different stages of evaluation.

CONCLUSION

The findings of the study suggest that using functional stretching exercises can improve functional outcomes in chronic spastic stroke patients.

Feasibility and Effectiveness of Intervention Programmes Integrating Functional Exercise into Daily Life of Older Adults: A Systematic Review

BACKGROUND

Traditionally, exercise programmes for improving functional performance and reducing falls are organised as structured sessions. An alternative approach of integrating functional exercises into everyday tasks has emerged in recent years.

OBJECTIVES

Summarising the current evidence for the feasibility and effectiveness of interventions integrating functional exercise into daily life.

METHODS

A systematic literature search was conducted including articles based on the following criteria: (1) individuals ≥60 years; (2) intervention studies of randomised controlled trials (RCTs) and non-randomised studies (NRS); (3) using a lifestyle-integrated approach; (4) using functional exercises to improve strength, balance, or physical functioning; and (5) reporting outcomes on feasibility and/or effectiveness. Methodological quality of RCTs was evaluated using the PEDro scale.

RESULTS

Of 4,415 articles identified from 6 databases, 14 (6 RCTs) met the inclusion criteria. RCT quality was moderate to good. Intervention concepts included (1) the Lifestyle-integrated Functional Exercise (LiFE) programme integrating exercises into everyday activities and (2) combined programmes using integrated and structured training. Three RCTs evaluated LiFE in community dwellers and reported significantly improved balance, strength, and functional performance compared with controls receiving either no intervention, or low-intensity exercise, or structured exercise. Two of these RCTs reported a significant reduction in fall rate compared with controls receiving either no intervention or low-intensity exercise. Three RCTs compared combined programmes with usual care in institutionalised settings and reported improvements for some (balance, functional performance), but not all (strength, falls) outcomes. NRS showed behavioural change related to LiFE and feasibility in more impaired populations. One NRS comparing a combined home-based programme to a gym-based programme reported greater sustainability of effects in the combined programme.

CONCLUSIONS

This review provides evidence for the effectiveness of integrated training for improving motor performances in older adults. Single studies suggest advantages of integrated compared with structured training. Combined programmes are positively evaluated in institutionalised settings, while little evidence exists in other populations. In summary, the approach of integrating functional exercise into daily life represents a promising alternative or complement to structured exercise programmes. However, more RCTs are needed to evaluate this concept in different target populations and the potential for inducing behavioural change.

The effects of eyeball exercise on balance ability and falls efficacy of the elderly who have experienced a fall: A single-blind, randomized controlled trial

PURPOSE

The purpose of this study was to investigate the effects of eyeball exercise on balance and fall efficacy of the elderly who have experienced a fall.

MATERIAL AND METHODS

Subjects were randomly assigned to the eyeball exercise group (n=30) or functional exercise group (n=31). All subjects received 30 sessions for 10 weeks. To identify the effects on balance, static and dynamic balance were measured using the center of pressure (CoP) measurement equipment and Timed Up and Go Test (TUGT) respectively. Fall efficacy was evaluated using the modified efficacy scale (MFES). The outcome measurements were performed before and after the 10 weeks training period.

RESULTS

After 10 weeks, static balance, dynamic balance, and fall efficacy were significantly improved in both groups. Also, there were significant differences in the outcome measures between both groups (p<0.05).

CONCLUSIONS

These results indicate that eyeball exercise is beneficial to improve the fall efficacy as well as the balance of the elderly compared with functional exercise. Eyeball exercise would be useful to improve balance and fall efficacy of the elderly who have experienced a fall.

Functional exercise in combination with auricular plaster therapy is more conducive to rehabilitation of menopausal women patients with anxiety disorder

OBJECTIVE

Observe the effect of functional exercise in combination with auricular plaster therapy on menopausal women patients with anxiety disorder.

METHOD

Select 45 menopausal women patients with anxiety disorder and then adopt random digital table to divide them into a functional exercise group, an auricular plaster therapy group and a combination group. Each group consists of 15 patients. The patients in the functional exercise group do yoga exercise twice a day; those in the auricular plaster therapy group are provided with the auricular plaster therapy twice a day; those in the combination group do yoga exercise and then they are provided with the auricular plaster therapy twice a day. Before the treatment and after 12 weeks' treatment, respectively detect and compare the selected patients in the three groups in respect HAMA score, physical function score and mental function score; And the cured patients are followed up for 3 months to compare recurrence rate of each group.

RESULTS

After 12 weeks' treatment, HAMA score, physical function score and mental function score of the combination group are obviously better than those of another two groups (P<0.05); Of the cure rate and the recurrence rate within 3 months, the cure rate of the combination group is higher and the recurrence rate is low.

CONCLUSION

Through the functional rehabilitation exercise in combination with the auricular plaster, the combined curative effect is obviously better than that of single treatment and the clinical recurrence rate is significantly lower than that of single treatment. It shows that the combined treatment method presents obvious synergistic effect and the synergistic treatment is more beneficial to improve the curative effect.

Activity progression for anterior cruciate ligament injured individuals

BACKGROUND

Functional exercises are important in the rehabilitation of anterior cruciate ligament deficient and reconstructed individuals but movement compensations and incomplete recovery persist. This study aimed to identify how tasks pose different challenges; and evaluate if different activities challenge patient groups differently compared to controls.

METHODS

Motion and force data were collected during distance hop, squatting and gait for 20 anterior cruciate ligament deficient, 21 reconstructed and 21 controls.

FINDINGS

Knee range of motion was greatest during squatting, intermediate during hopping and smallest during gait (P < 0.01). Peak internal knee extensor moments were greatest during distance hop (P < 0.01). The mean value of peak knee moments was reduced in squatting and gait (P < 0.01) compared to hop. Peak internal extensor moments were significantly larger during squatting than gait and peak external adductor moments during gait compared to squatting (P < 0.01). Fluency was highest during squatting (P < 0.01). All patients demonstrated good recovery of gait but anterior cruciate ligament deficient adopted a strategy of increased fluency (P < 0.01). During squatting knee range of motion and peak internal knee extensor moment were reduced in all patients (P < 0.01). Both anterior cruciate ligament groups hopped a shorter distance (P < 0.01) and had reduced knee range of motion (P < 0.025). Anterior cruciate ligament reconstructed had reduced fluency (P < 0.01).

INTERPRETATION

Distance hop was most challenging; squatting and gait were of similar difficulty but challenged patients in different ways. Despite squatting being an early, less challenging exercise, numerous compensation strategies were identified, indicating that this may be more challenging than gait.
