Concurrent Force Feedback on Load Symmetry in Total Knee Arthroplasty Patients.

Load asymmetry can be present before and after total knee arthroplasty (TKA), which may affect progress during knee rehabilitation in an outpatient sports medicine setting. Current rehabilitation primarily focuses on strength, pain, and range of motion deficits; however, recent evidence suggests the use of movement retraining strategies such as load feedback to address load asymmetry. Therefore, the purpose of this study was to examine how a single session of concurrent force feedback influences load symmetry during the leg-press and body-weight squat exercises in individuals following TKA. Additionally, a secondary purpose was to examine the retention of any changes over the course of a week. Case-series study. This observational, repeated-measures study design examined the effect of concurrent force feedback training on the mean and standard deviation of load symmetry index during the leg press and squat exercises in 26 patients with TKA in an outpatient sports medicine clinic.The load asymmetry was measured with loadpad sensors placed underneath the each extremity during leg press and squat (baseline), after one training session consisting of concurrent force feedback during these exercises within a single physical therapy session (post feedback), and after seven to ten days of a washout period (post retention). Separate 2 x 3 repeated measures analysis of variance was used to compare the mean and standard deviation of load symmetry across exercise (leg press and squat) and across time (baseline, post feedback and post retention). There was a time effect for the mean load symmetry index (p=0.027) but not for the standard deviation (p=0.441) during these exercises. The leg press showed a greater mean symmetry index compared to the squat regardless of time (p=0.001). A reduction in the mean load symmetry index following concurrent feedback training suggests improved use of the surgical limb during both leg press and squat exercises during the same therapy session but the more symmetric loading pattern was not retained one week later. Overall, the leg press showed greater mean asymmetry than the squat. Standard deviation in the load symmetry index did not change across time or by exercise. 3©The Author(s).

Optimized progression of Full-Body In-Bed Gym workout: an educational case report.

People suffering from fatigue syndromes spend less time exercising each day, thus aggravating their motor difficulties. Indeed, muscles and mobility deteriorate with age, while exercising muscles is the only sure countermeasure. It is useful to offer a safe and toll-free rehabilitation training: Full-Body In-Bed Gym, easy to learn and performe at home. We suggest a 10-20 min daily routine of easy and safe physical exercises that may improve the main 200 skeletal muscles used for every-day activities. Many of the exercises can be performed in bed (Full-Body In-Bed Gym), so hospital patients can learn this light workout before leaving the hospital. The routine consists of series of repetitions of 15 bodyweight exercises to be performed one after the other without time breaks in between. Alternating sequences of arm and leg exercises are followed by moving body parts in lying and sitting positions in bed. These are followed by series of tiptoeing off the bed. Progressive improvements can be tested by a series of push-ups on the floor. Starting from 3-5, number of repetitions are increased by adding 3 more every week. To maintain or even shorten total daily time of workout each movement is weekly speeded up. The devoted time every morning (or at least five days a week) to train all the major muscles of the body can remain under 10 minutes. Because there are no breaks during and between sets, the final push-ups become very challenging: at the end of the daily workout heart rate, depth and number of ventilations and frontal perspiration increase for a few minutes. We here provide an example of how to implement the progression of the Full-Body In-Bed Gym presenting an educational Case Report of a trained 80-year old person in stable pharmacological managements. In addition to strengthening the main muscles, including the ventilatory muscles, Although performed in bed, Full-Body In-Bed Gym is a resistance training equivalent to a short jog.. Started in early winter and continued regularly throughout spring and summer, Full-Body In-Bed Gym can help maintain independence of frail people, including those younger persons suffering with the fatigue syndrome related to the viral infection of the recent COVID-19 pandemic.

An at-home, virtually administered graded exertion protocol for use in concussion management: Preliminary evaluation of safety and feasibility in healthy youth and children with subacute concussion.

Graded exertion testing (GXT) is an important tool for concussion management, as it is used to personalize post-concussion exercise prescription and return athletes to sport. However, most GXT requires expensive equipment and in-person supervision. Our objective was to assess the safety and feasibility of the Montreal Virtual Exertion (MOVE) protocol, a no-equipment, virtually compatible GXT, in healthy children and children with subacute concussion. Cross-sectional. The MOVE protocol consists of seven stages of bodyweight and plyometric exercises performed for 60 seconds each. Twenty healthy (i.e., non-concussed) children completed the MOVE protocol virtually over Zoom Enterprise. Next, thirty children with subacute concussion (median: 31.5 days post-injury) were randomized to the MOVE protocol or Buffalo Concussion Treadmill Test (BCTT), which increases the incline or speed of the treadmill every minute until maximum exertion. Out of an abundance of caution, all concussed participants completed the MOVE protocol in an in-person clinical space. However, the test evaluator was stationed in a different room within the clinic and administered the MOVE protocol using Zoom Enterprise software to mimic telehealth conditions. Safety and feasibility outcomes were recorded throughout GXT, including heart rate, rate of perceived exertion (RPE), and symptom outcomes. No adverse events were recorded, and all feasibility criteria were successfully met in healthy youth and youth with concussion. Among concussed youth, increases in heart rate (MOVE: 82.4  17.9 bpm, BCTT: 72.1  23.0 bpm; t(28)=1.36, p=0.18), RPE (MOVE: 5.87  1.92, BCTT: 5.07  2.34, t(28)=1.02, p=0.32), and overall symptom presentation were similar between the MOVE and BCTT protocols. The MOVE protocol is a safe and feasible GXT that in healthy youth and youth with subacute concussion. Future studies should assess the fully virtual administration of the MOVE in children with concussion, MOVE protocol tolerability in children with acute concussion, and whether the MOVE protocol can be used to guide individualized exercise prescription.

Safety and feasibility of a randomized controlled trial testing a personalized exercise program in patients with cancer: The CHOiCE trial.

e24045 Background: Growing evidence suggests that physical exercise (EX) may reduce mortality and recurrence risk in patients (pts) with cancer, as well as help in managing cancer treatment side effects and improve quality of life (QoL). Despite these well-recognized benefits, most pts are insufficiently active, and compliance with the EX intervention is often challenging. This pilot study aimed to evaluate the safety, feasibility, and preliminary efficacy of a 3-month EX-intervention in pts with cancer. Methods: A pilot, two-center randomized controlled trial was conducted on pts with different cancers at early stages. Pts allocated in the 3-month EX intervention participated in bi-weekly aerobic and resistance training tailored to the patient's baseline condition and preferences. The duration of aerobic training progressively increased over weeks, whereas the resistance component consisted of body weight or elastic-bands exercises performed in 2-3 sets of 8-12 repetitions. EX intensity was moderate and monitored using the 10-point Borg Rating of the Perceived Exertion Scale. Pts randomized to control received usual care. Primary study endpoints were safety, monitored through the Common Terminology Criteria for Adverse Events (AEs), and feasibility, evaluated through recruitment rate, adherence, and withdrawals. Secondary endpoints included functional capacity, using the Six minutes walking test, and muscle strength, with the handgrip and leg press test. European Organization for Research and Treatment of Cancer Quality of Life and Core Questionnaire (EORTC- QLQ-C30) was used to assess the QoL. Descriptive statistics was applied, and repeated-measures analysis of variance was used to evaluate within- and between-group differences. Results: With a 38% recruitment rate, 57 pts were randomized (56 years; 68% breast, 14% colorectal) to the EX-intervention (n = 37) and controls (n = 20). Five dropouts occurred, n = 3 in the EX-group (leukemia onset n = 1, psychiatric disorder n = 1, gonarthrosis n = 1), and n = 2 in the controls (lack of interest n = 2). Adherence to EX-sessions was high, 93%. Concerning safety, three AEs were reported: worsening in the lymphedema, Grade 1 (n = 2), and elbow inflammation, Grade 1. Compared to the controls, EX-group reported a significant increase in functional capacity (within group, p < 0.01), and lower limb strength (within and between group, p < 0.01). Regarding QoL, EX produced enhancements in social function (within group, p < 0.05), fatigue (within group, p < 0.05), nausea and vomiting (within group p < 0.01), dyspnea (within group, p < 0.05), insomnia (within group, p < 0.05), and loss of appetite (within group, p < 0.01). Conclusions: Preliminary findings support the feasibility of a combined aerobic and resistance EX in pts with cancer with minimal AEs. Moreover, improvements in physical parameters and some domains of QoL were detected. Clinical trial information: NCT04226508 .

바디웨이트 그룹운동이 비만여대생들의 체형개선변화와 혈중스트레스요인에 미치는 영향

This study was conducted to find out how it affects changes in body shape and blood stress factors by having obese female college students perform body weight exercise for 8 weeks. The study subjects were divided into 10 body weight group and 10 control group based on 20 obese female college students. Two-way repeated ANOVA was conducted to see the significance and interaction effect between the two groups based on the data obtained through two pre- and post-measurements through 8 weeks of body weight exercise, and based on the above results, the following conclusions were drawn. derived. First, in the effect of improving the body shape of obese female college students through body weight exercise, there was a significant difference in weight (measurement period) and body fat percentage (measurement period, group), and it was found that there was an interaction effect. Second, in the effect of blood stress of obese female college students through body weight exercise, there was a significant difference in blood active oxygen (measurement period) and blood lactic acid (measurement period), and it was found that there was an interaction effect. Recently, various exercise methods have been proposed for diet and health promotion. The body weight exercise presented in this study has also been shown to make positive changes in eliminating obesity, and for modern people who lack time, if performed regularly at home training or a place where only space is used, obesity can be prevented. It will relieve blood pressure and reduce blood stress, leading to a healthy college life and healthy adulthood and middle age.

Prevalence of Obesity and Health-Promoting Lifestyle Among Nurses in a Tertiary Hospital, Malaysia

The study was conducted to determine the prevalence of obesity and health-promoting lifestyles among nurses in a tertiary hospital, Malaysia. Descriptive cross-sectional study of 417 nurses was conducted between July and August 2022 using the Health-Promoting Lifestyle Profile II (HPLPII) scale. The study found majority of the respondents were obese (n = 233, 55.9%). The total score of Health-Promoting Lifestyle Profile II (HPLP-II) was 142.46±22.70. Body Mass Index and health responsibility were statistically correlated (r = 0.129, p = 0.009). Obesity among nurses is prevalent. Body weight management and exercise programs should be implemented to achieve healthy lifestyle among nurses.

P493 ASSOCIATION BETWEEN IMPROVEMENT IN PHYSICAL FITNESS AND ANTHROPOMETRIC PARAMETERS WITH MAINTENANCE OF PHYSICAL EXERCISE HABITS IN A POPULATION OF PATIENTS WITH ISCHEMIC HEART DISEASE UNDERGOING A REHABILITATION CYCLE WITH 6 MONTHS FOLLOW–UP

Abstract Background Increased physical activity is associated with a reduction in all–cause mortality and may increase life expectancy, an effect strongly linked to a reduction in the risk of cardiovascular (CV) disease. Regular aerobic exercise (EX) results in modest reductions in waist circumference (CIRC) (associated with CV mortality) and visceral adipose tissue. Vigorous intensity EX may offer greater benefits than moderate intensity. Aim of the study: To evaluate whether the continuation of EX after Cardiac Rehabilitation (CR) leads to an improvement in physical capacity and parameters related to CV pathology of patients (PZ) with ischemic heart disease (IC). Methods retrospective observational study on patients referred to the Outpatient CR of the O.C. S.M. del Prato (Feltre) from January 2018 to May 2021. Of the initial population of 270 PZ, 47 did not show up at the f.–up, 22 did not perform 6MWT at the f.–up and 33 had CR indications other than IC. The Outpatient CR consisted of 10 monthly sessions with 3 modalities: • educational (ED) + supervised EX • ED only • online (Covid period). Supervised EX: soft bodyweight gymnastics (30 min) + 30 minutes monitored moderate to vigorous supervised EX on stationary bikes and treadmills ED: frontal lessons (1–2 h) multidisciplinary (doctor, nurse, dietician, psychologist) aimed at improving the patient‘s management of CV disease and risk factors. On–line: soft bodyweight gymnastics (30 min) + ED by videoconference The f.–up was on average 6 months after the CR. Statistical processing with Jamovi 2.3.13 Materials and methods: At admission to CR and at f.–up, weight, height, CIRC, calculated BMI were measured, performed 6–minute walk test (6MWT) with Borg scale detection. At the f.–up a questionnaire was self–administered and adherence to EX, bodyweight exercise, how often, attendance at a gym, use of heart rate monitor (CF), etc. were declared. Conclusions The 6MWT improves in a statistically significant way in all PZs at f.–up except in those who declare not to perform EF. Significant improvements in CIRC, BMI and Borg were observed in PCS performing EX more frequently weekly (2–4 times), using CF and in PCS undergoing complete RC (ED + EX). No predictors of improvement at 6 months of the examined variables were identified.

Using Smart Home Technologies to Promote Physical Activity Among the General and Aging Populations: Scoping Review.

Health-monitoring smart homes are becoming popular, with experts arguing that 9-to-5 health care services might soon become a thing of the past. However, no review has explored the landscape of smart home technologies that aim to promote physical activity and independent living among a wide range of age groups. This review aims to map published studies on smart home technologies aimed at promoting physical activity among the general and aging populations to unveil the state of the art, its potential, and the research gaps and opportunities. Articles were retrieved from 6 databases (PubMed, CINAHL, Scopus, IEEE Xplore, ACM Library, and Web of Science). The criteria for inclusion were that the articles must be user studies that dealt with smart home or Active Assisted Living technologies and physical activity, were written in English, and were published in peer-reviewed journals. In total, 3 researchers independently and collaboratively assessed the eligibility of the retrieved articles and elicited the relevant data and findings using tables and charts. This review synthesized 20 articles that met the inclusion criteria, 70% (14/20) of which were conducted between 2018 and 2020. Three-quarters of the studies (15/20, 75%) were conducted in Western countries, with the United States accounting for 25% (5/20). Activities of daily living were the most studied (9/20, 45%), followed by physical activity (6/20, 30%), therapeutic exercise (4/20, 20%), and bodyweight exercise (1/20, 5%). K-nearest neighbor and naïve Bayes classifier were the most used machine learning algorithms for activity recognition, with at least 10% (2/20) of the studies using either algorithm. Ambient and wearable technologies were equally studied (8/20, 40% each), followed by robots (3/20, 15%). Activity recognition was the most common goal of the evaluated smart home technologies, with 55% (11/20) of the studies reporting it, followed by activity monitoring (7/20, 35%). Most studies (8/20, 40%) were conducted in a laboratory setting. Moreover, 25% (5/20) and 10% (2/20) were conducted in a home and hospital setting, respectively. Finally, 75% (15/20) had a positive outcome, 15% (3/20) had a mixed outcome, and 10% (2/20) had an indeterminate outcome. Our results suggest that smart home technologies, especially digital personal assistants, coaches, and robots, are effective in promoting physical activity among the young population. Although only few studies were identified among the older population, smart home technologies hold bright prospects in assisting and aiding older people to age in place and function independently, especially in Western countries, where there are shortages of long-term care workers. Hence, there is a need to do more work (eg, cross-cultural studies and randomized controlled trials) among the growing aging population on the effectiveness and acceptance of smart home technologies that aim to promote physical activity.

The Effect of 6 Weeks of Body weight Exercises on the Respiratory Function of overweight Women

The prevalence of obesity and overweight all over the world due to the mechanization of lifestyle and people’s use of ready-made foods is increasing and affecting health and is closely related to major problems. One of the diseases that has a positive and frequent relationship with obesity is a respiratory disease. Obesity weakens people’s lung function and respiratory tract through two mechanisms, mechanical and inflammatory. The mechanical effect of obesity is such that it can affect the respiratory mechanics of the lungs and chest wall and cause asthma or pseudo-asthmatic shortness of breath and increase the response of the respiratory tract. In this study, we investigated the effect of 6 weeks of bodyweight training on the respiratory function of overweight women. For this purpose, in this research, 30 obese women aged 25 to 40 years were randomly divided into two control and training groups. The height meter and weight were calibrated with a digital scale and the body mass index was calculated by calculating the height and weight and the corresponding formula. The training program of the experimental group was for 6 weeks, 3 sessions per week and 60 minutes in each session. The training session included a 10-minute warm-up at the beginning of the workout and a 10-minute cool-down at the end of the workout. According to the present study, the percentage of fat in the training group was significantly reduced compared to the control. Also, there was a significant difference between the two groups in the FVC respiratory indices and the FEV1/FVC ratio. This was even though no significant difference was observed in the FEV1 index between the training and control groups. . Resistance training improves body composition by increasing metabolism and energy consumption and reducing fat mass. Research has shown that resistance training is effective in improving body composition due to increasing muscle volume and reducing fat percentage. In the present study, it was observed that resistance training with bodyweight could improve FVC. Resistance training is effective in improving the pulmonary indices of people by improving the skeletal muscle system and posture. The final result of this research showed us that resistance training with body weight in overweight women can improve body composition and respiratory function.

School-Based Circuit Training Intervention Improves Local Muscular Endurance in Primary School Students: A Randomized Controlled Trial.

This study aimed to explore the effectiveness of a 12-week circuit training program in improving local muscular endurance in normal-weighted primary school students. The study involved a parallel-group randomized trial with 606 primary school boys assigned to an experimental or a control group. The participants underwent a 12-week circuit training program that involved multi-joint, total-body workouts using body weight, resistance bands, and medicine ball exercises. The study measured the participants' local muscular endurance during sit-ups, dynamic trunk extensions on a Roman bench (DTE), and push-ups. After adjusting for the baseline, the treatment-grade interaction was significant for sit-ups (F = 7.74, p < 0.001, ηp2 = 0.04), DTE (F = 6.49, p < 0.001, ηp2 = 0.03), and push-ups (F = 9.22, p < 0.001, ηp2 = 0.05), where the experimental treatment was more beneficial than the control. The treatment effect seemed to vary depending on the individual's baseline local muscle endurance capacity. As the baseline local muscular endurance values increased, the treatment and grade effects became less beneficial. A 12-week circuit training program involving body weight, resistance bands, and medicine ball exercises suits school-based programs and can improve local muscular endurance in normal-weighted primary school boys. The experimental treatment was more effective than the control, and the individual baseline muscular endurance should be considered when designing training programs.

Increased muscle force does not induce greater stretch-induced damage to calf muscles during work-matched heel drop exercise

PurposeTo investigate the effect of muscle force during active stretch on quantitative and qualitative indicators of exercise-induced muscle damage (EIMD) in the medial gastrocnemius (MG) muscle.MethodsTwelve recreationally active volunteers performed two trials of an eccentric heel drop exercise. Participants performed a single bout of low-load (body weight) and high-load (body weight + 30% body weight) exercises on separate legs. The total mechanical work output for each condition was matched between legs. Before, two hours and 48 h after each bout of eccentric exercise, electrically stimulated triceps surae twitch torque, muscle soreness, MG active fascicle length at maximum twitch torque and muscle passive stiffness were collected. Triceps surae electromyographic (EMG) activity, MG fascicle stretch and MG muscle–tendon unit (MTU) length were measured during the eccentric tasks.ResultsThe high-load condition increased triceps surae muscle activity by 6–9%, but reduced MG fascicle stretch (p < 0.001). MTU stretch was similar between conditions. The greater muscle force during stretch did not give rise to additional torque loss (5 vs 6%) or intensify muscle soreness.ConclusionsAdding 30% body weight during eccentric contractions has a modest impact on exercise-induced muscle damage in the medial gastrocnemius muscle. These results suggest that muscle load may not be an important determinant of stretch-induced muscle damage in the human MG muscle. The muscle investigated does exhibit large pennation angles and high series elastic compliance; architectural features that likely buffer muscle fibres against stretch and damage.

A mixed-methods exploration of attitudes towards pregnant Facebook fitness influencers

BackgroundExercise during pregnancy is associated with various health benefits for both mother and child. Despite these benefits, most pregnant women do not meet physical activity recommendations. A known barrier to engaging in exercise during pregnancy is a lack of knowledge about appropriate and safe exercise. In our current era of social media, many pregnant women are turning to online information sources for guidance, including social media influencers. Little is known about attitudes towards pregnancy exercise information provided by influencers on social media platforms. This study aimed to explore attitudes towards exercise during pregnancy depicted by social media influencers on Facebook, and user engagement with posted content.MethodsA mixed-methods approach was used to analyse data from 10 Facebook video posts of social media influencers exercising during pregnancy. Quantitative descriptive analyses were used to report the number of views, shares, comments and emotive reactions. Qualitative analysis of user comments was achieved using an inductive thematic approach.ResultsThe 10 video posts analysed were viewed a total of 12,117,200 times, shared on 11,181 occasions, included 13,455 user comments and 128,804 emotive icon reactions, with the most frequently used icon being ‘like’ (81.48%). The thematic analysis identified three themes associated with attitudes including [1] exercise during pregnancy [2] influencers and [3] type of exercise. A fourth theme of community was also identified. Most user comments were associated with positive attitudes towards exercise during pregnancy and the influencer. However, attitudes towards the types of exercise the influencer performed were mixed (aerobic and body weight exercises were positive; resistance-based exercise with weights were negative). Finally, the online community perceived by users was mostly positive and recognised for offering social support and guidance.ConclusionsUser comments imply resistance-based exercise with weights as unsafe and unnecessary when pregnant, a perception that does not align with current best practice guidelines. Collectively, the findings from this study highlight the need for continued education regarding exercise during pregnancy and the potential for social media influencers to disseminate evidence-based material to pregnant women who are highly receptive to, and in need of reliable health information.

The Effects of a Novel Lateral Ankle Strengthening Program in NCAA Division III Football Players

Introduction: Lateral ankle sprains (LAS) are among the most reported injuries in college athletics, typically resulting from excessive closed-kinetic chain (CKC) supination. The purpose of this study was to compare the effects of a novel CKC supination-style ankle strengthening program to a traditional ankle strengthening program on common LAS indices. Methods: Thirty NCAA Division III collegiate football players (19.9±1.0yrs., 182.2±6.9cm, 98.8±18.0kg) were randomly assigned to a novel exercise (SUP, n = 16) or traditional exercise group (TRA, n = 14). The SUP group performed dynamic bodyweight exercises with controlled ankle supination while the TRA group performed traditional ankle strengthening exercise using elastic bands and stability exercises 3 times per week for 6 weeks. Right and left ankle inversion (InvR, InvL) and eversion (EvR, EvL) strength (kg), ankle inversion range of motion (romR, romL) (deg.), and figure-8 hop test (fig8R, fig8L) (s) performance were assessed pre- and post-intervention. Results: Both groups showed significant improvements in all outcome measures pre- to post-test (ΔInvR: TRA 4.5±4.3kg, SUP 5.0±4.4kg; ΔIvL: TRA 4.0±3.8kg, SUP 4.8±3.6kg; ΔEvR: TRA 5.7±4.3kg, SUP 4.7±3.3kg; ΔEvL: TRA 4.7±2.9kg, SUP 4.5±2.2kg; ΔromR: TRA 4.5±2.6°, SUP 4.9±3.0°; ΔromL: TRA 4.7±4.5°, SUP 4.6±5.1°; Δfig8R: TRA -0.43±0.20s, SUP -0.37±0.31s; Δfig8L: TRA -0.40±0.22s, SUP -0.34±0.30s; p’s&lt;0.001), with no difference between groups. Conclusions: A bodyweight, supination style ankle training program can improve physical qualities related to LAS to a similar extent as a traditional program, and therefore, could potentially be a viable alternative strategy for reducing LAS in Division III NCAA football players.

Barriers and enablers associated with participation in a home-based pragmatic exercise snacking program in older adults delivered and monitored by Amazon Alexa: a qualitative study

Background‘Exercise snacking’, which is characterised by shorter and more frequent exercise bouts compared with traditional exercise guidelines, may be an acceptable strategy for increasing physical activity and reducing sedentary behaviour in older adults.AimThe aim of this study was to evaluate the enablers and barriers for older adults associated with participation in a home-based exercise snacking program delivered and monitored using an Amazon Echo Show 5 device (Alexa).MethodsThis study used an interpretive description qualitative design to conduct semi-structured interviews following a 12-week pilot study in 15 adults aged 60–89 years with at least one chronic condition. All participants were prescribed a home based, individualised, lower limb focussed ‘exercise snacking’ program (involving ≤ 10 min of bodyweight exercises 2–4 times per day) delivered and monitored by an Alexa. Qualitative interview data were analysed using thematic analysis.ResultsAll 15 participants (mean age 70.3 years) attended the semi-structured interview. Themes including time efficiency, flexibility, perceived health benefits, and motivation were enablers for participation in the ‘exercise snacking’ program. A lack of upper body exercises and omission of exercise equipment in the program, as well as a lack of time and motivation for performing exercise snacks three or more times per day, were barriers to participation.ConclusionWhile ‘exercise snacking’ is acceptable for older adults, future trials should provide equipment (e.g. adjustable dumbbells, exercise bands), prescribe whole-body exercise programs, and establish strategies to support participation in more than three exercise snacks per day.

Accessible Guide for People With Intellectual Disabilities in a Fitness Environment: A Delphi Study.

The purpose of this study was to draw consensus among an expert panel regarding essential elements of an accessible fitness center guide for people with intellectual disabilities that will enable them to engage in physical activity fully and effectively. The study was situated in the socioecological model of disability. Researchers drew expert consensus regarding the essential features of accessible guides in fitness environments. A three-round Delphi procedure was used, involving repeated circulation of the questionnaire to an expert panel (N = 33). The panel was asked to rate the importance and adequacy of 66 items regarding the accessible fitness guide. A consensus was reached regarding 43 items after three rounds. The items include 7 body-weight exercises, 2 machine exercises, 12 environment-related items, 15 exercise preparations, 4 social etiquettes, and 3 emergencies.

Effects of Blood Flow Restriction Training on Various Physiological Factors among Different Population: A Narrative Review

Purpose: Blood flow restriction (BFRT) is a recent rehabilitation modality in which a tourniquet is used toreduce arterial inflow and occlude venous outflow along with a set of exercise or resistance training. This studyhighlights various aspects and physiological factors which are affected by BFRT along with different exerciseregimens. Relevance: BFRT provides advantages over traditional resistance training (moderate-heavy) as itprovides muscular adaptations and increase in muscle cross sectional area despite relatively low external loads,producing less muscle damage and increasing frequency of training. Traditional resistance training usuallyused exercise loads of 70% of 1 repetition maximum (1RM) and it is known that stress on connective tissuescan be detrimental for elderly population and rehabilitative patients,but in BFRT only 20%-40% of 1RM instudies have shown consistently to increase muscle strength, hypertrophy and angiogenesis. It is very popularamong practitioners, researchers, physiotherapists and athletes to increase muscle mass, endurance, strength andfunctional performance or activity of daily living. Studies show that resistance exercises coupled with BFRT arediverse which include body weight exercises, lower body exercises, upper body exercises, in-water exercises,older populations or clinical cases. Participants: Total 15 articles were included and reviewed. Only full textarticles from past ten years were included in this review. Methods: A literature search was performed usingGoogle Scholar and PubMed using terms blood flow restriction, resistance exercise, 1 repetition maximum.

Frequency, intensity and duration of muscle strengthening activity and associations with mental health

ObjectivesDespite growing emphasis on the benefits of physical activity for promoting mental health, inclusion of muscle-strengthening (MS) (e.g., body-weight exercises, resistance machines) activities is limited. Notably, few studies collectively assess MS behavioural frequency, duration, and intensity. To address the gap, the current study examined associations between frequency (days), intensity (rating of perceived exertion in relation to repetitions in reserve [RPE/RIR]), and duration (minutes per typical session) of MS activities on anxiety, depression, and mental well-being. MethodA cross-sectional study of 601 participants (Mean age = 30.92 years [SD = 12.70]; 57.7 % female) across Ireland was conducted. Participants completed a self-report questionnaire containing MS instruments previously used, or adapted from valid and reliable measures (i.e., International Physical Activity Questionnaire IPAQ, RPE/RIR), alongside, the Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-8 (PHQ-8) and the Mental Health Continuum- Short Form (MHC-SF). A multivariate regression model was tested in MPLUS, using dummy coding for MS frequency in relation to no activity (i.e., 0-days) non-adherence (i.e., 1-day), adherence (i.e., 2-days) and enhanced adherence (i.e., ≥3 days) to the MS public health guidelines, with the mental health variables representing the dependent variables. Intensity and duration were specified in the model as continuous variables; gender and age were included as statistical controls. ResultsThree or more days engaged in MS activities was associated with fewer anxiety (β = −0.12, p < .05) and depression (β = −0.14, p < .01) symptoms. Increased intensity had a negative association with anxiety (β = −0.10, p < .05) and depression (β = −0.15, p < .001). Unexpectedly, adherence to the MS guidelines (2-days) did not predict any of the mental health outcomes, whereas 1-day of MS activity was associated with fewer depression symptoms (β = −0.11). No effects were observed for mental well-being, and MS duration exerted a null effect across all mental health outcomes. ConclusionHigher frequency and intensity of MS activities may protect against anxiety and depression symptoms. Doing some MS activities (at least 1-day) is likely more beneficial than none for depression. Evidence-based, MS interventions may help curb mental illness rates, and future longitudinal, intervention-based research could consider inclusion of MS frequency, intensity and duration variables to enhance efforts to identify at-risk groups and trends within physical activity and mental illness surveillance.

Calculations of mean ocular perfusion pressure before and after exercise are conditioned by the formula used

AbstractPurpose: Blood pressure is a key parameter associated with ocular health and glaucoma. Additionally, brachial blood pressure serves to calculate ocular perfusion pressure. The main aim was to evaluate differences between the most used formulas to calculate mean brachial arterial blood pressure and the effects that physical exercise may have in this parameter.Methods: Fifteen physically active, healthy subjects (9 male 6 female, 24.07 ± 3.65 years) voluntarily performed a 15‐minute protocol consisting of combined exercise including, mobility, bodyweight exercises, running, dynamic stretching, and three sets of barbell back squat at low intensities. The formulas compared were 1) diastolic blood pressure (DBP) + 1/3 * (systolic blood pressure [SBP] ‐ DBP); 2) DBP + 0.412 * (SBP – DBP); 3) DBP + (0.333 + (0.0012 * heart rate)) * (SBP ‐ DBP); 4) DBP + (25.361 + 0.047 * heart rate + 0.163 * DBP) * (SBP ‐ DBP); 5) (SBP * DBP) ^ 1/2. A two‐way analysis of variance evaluated the effect of the exercise and the formula used to calculate the mean blood pressure.Results: Significant effects of the exercise (F(1, 14) = 88.66, p &lt; 0.001, η2 = 0.86), formula used (F(1.06, 14.86) = 250.23, p &lt; 0.001, η2 = 0.95), and their interaction (F(1.37, 19.11) = 54.75, p &lt; 0.001, η2 = 0.80) were observed in the resulting values. The post‐hoc results showed significant differences between most of the formulas both preexercise and postexercise.Conclusions: The results presented suggest that caution should be applied when using indirect formulas to estimate mean brachial arterial pressure. Future research should objectively evaluate mean blood pressure with a direct method to find the most reliable formula. Meanwhile, this study is published to raise awareness on the importance of choosing one or other methods when aiming to estimate with formulas physiological parameters related to ocular health.
