Analysis of the Impact of Yoga on Health Care Applications and Human Pose Recognition

Human Pose Recognition is a powerful computer vision strategy that has revealed several problems. Separating human exercise is beneficial in various fields, including health observation, biometrics, and a wide range of medical care applications. These days, yoga poses are famous for practice because they can improve muscular quality and increase breathing exercises. However, because evaluating yoga stances is complicated, experts will be unable to profit from the activities in the long run. For people who want to practice yoga at home, IoT-based yoga systems are required. Several studies have suggested that camera-based or wearable devices can better arrange yoga pose discovering approaches. On the other hand, camera-based methods have security and protection issues, and wearable device-based strategies have proven irrational in existing applications. A solid foundation and ongoing research in pose assessment are required to construct such a framework. First, using real-time data, this paper investigates the effect of yoga on people experiencing various anxiety levels. Second, a comprehensive survey of yoga pose detection frameworks, ranging from machine learning to deep learning techniques and assessment measurements, was carried out.

The Effect of a Resistance Training, Detraining and Retraining Cycle on Postural Stability and Estimated Fall Risk in Institutionalized Older Persons: A 40-Week Intervention.

Physical inactivity and low levels of muscle strength can lead to the early development of sarcopenia and dynapenia, which may increase the number and risk of falls in the elderly population. Meanwhile, exercise programs can stop or even revert the loss of muscle mass, strength, power, and functional capacity and consequently decrease the risk of falls in older adults. However, there is a lack of studies investigating the effect of strengthening programs in octogenarians. The present study investigates the effects of 40 weeks of a training-detraining-retraining cycle of muscle strength exercise program on postural stability and estimated fall risk in octogenarians. Twenty-seven institutionalized participants were allocated into two groups: the muscular strength exercise group (MSEG, n = 14) and control group (CG, n = 13). After the first training period, the MSEG improved postural stability and decreased the estimated fall risk by 7.9% compared to baseline. In comparison, CG worsened their stability and increased their risk of falling by more than 17%. No significant changes were found between groups in the detraining and the retraining period. This study demonstrated that strength exercise effectively improved postural control and reduced fall risk scores. In addition, the interventions were able to reduce the forward speed of postural control deterioration in octogenarians, with great increments in the first months of exercise.

The beneficial effect of chronic muscular exercise on muscle fragility is increased by Prox1 gene transfer in dystrophic mdx muscle.

Greater muscle fragility is thought to cause the exhaustion of the muscle stem cells during successive degeneration/repair cycles, leading to muscle wasting and weakness in Duchenne muscular dystrophy. Chronic voluntary exercise can partially reduce the susceptibility to contraction induced-muscle damage, i.e., muscle fragility, as shown by a reduced immediate maximal force drop following lengthening contractions, in the dystrophic mdx mice. Here, we studied the effect of Prospero-related homeobox factor 1 gene (Prox1) transfer (overexpression) using an AAV on fragility in chronically exercised mdx mice, because Prox1 promotes slower type fibres in healthy mice and slower fibres are less fragile in mdx muscle. Both tibialis anterior muscles of the same mdx mouse received the transfer of Prox1 and PBS and the mice performed voluntary running into a wheel during 1 month. We also performed Prox1 transfer in sedentary mdx mice. In situ maximal force production of the muscle in response to nerve stimulation was assessed before, during and after 10 lengthening contractions. Molecular muscle parameters were also evaluated. Interestingly, Prox1 transfer reduced the isometric force drop following lengthening contractions in exercised mdx mice (p < 0.05 to 0.01), but not in sedentary mdx mice. It also increased the muscle expression of Myh7 (p < 0.001), MHC-2x (p < 0.01) and Trpc1 (p < 0.01), whereas it reduced that one of Myh4 (p < 0.001) and MHC-2b (p < 0.01) in exercised mdx mice. Moreover, Prox1 transfer decreased the absolute maximal isometric force (p < 0.01), but not the specific maximal isometric force, before lengthening contraction in exercised (p < 0.01) and sedentary mdx mice. Our results indicate that Prox1 transfer increased the beneficial effect of chronic exercise on muscle fragility in mdx mice, but reduced absolute maximal force. Thus, the potential clinical benefit of the transfer of Prox1 into exercised dystrophic muscle can merit further investigation.

Changes in the Cardiotoxic Effects of Lead Intoxication in Rats Induced by Muscular Exercise.

Exposure to lead is associated with an increased risk of cardiovascular diseases. Outbred white male rats were injected with lead acetate intraperitoneally three times a week and/or were forced to run at a speed of 25 m/min for 10 min 5 days a week. We performed noninvasive recording of arterial pressure, electrocardiogram and breathing parameters, and assessed some biochemical characteristics. Electrophoresis in polyacrylamide gel was used to determine the ratio of myosin heavy chains. An in vitro motility assay was employed to measure the sliding velocity of regulated thin filaments on myosin. Isolated multicellular preparations of the right ventricle myocardium were used to study contractility in isometric and physiological modes of contraction. Exercise under lead intoxication normalized the level of calcium and activity of the angiotensin-converting enzyme in the blood serum, normalized the isoelectric line voltage and T-wave amplitude on the electrocardiogram, increased the level of creatine kinase-MB and reduced the inspiratory rate. Additionally, the maximum sliding velocity and the myosin heavy chain ratio were partly normalized. The effect of exercise under lead intoxication on myocardial contractility was found to be variable. In toto, muscular loading was found to attenuate the effects of lead intoxication, as judged by the indicators of the cardiovascular system.

Neuroprotective effects of strength training in a neuroinflammatory animal model

BackgroundThe preventive role of muscular strength on diminishing neuroinflammation is yet unknown. In this study, the role of the prophylactic muscular strength exercise was investigated in order to verify whether it would diminish cognitive alterations and modify the antioxidant intracellular scenery in an animal neuroinflammatory model in of the CA1 region of the hippocampus.MethodsThe animals received muscular strength training (SE) three times a week for eight weeks. Subsequently, the stereotaxic surgery was performed with an intra-hippocampal infusion of either saline solution (SAL) or lipopolysaccharide (LPS). Next, we performed the behavioral tests: object recognition and social recognition. Then, the animals were euthanized, and their hippocampus and prefrontal cortex were collected. In another moment, we performed the dosage of the antioxidant activity and histological analysis.ResultsThe results showed that the muscular strength exercises could show a beneficial prophylactic effect in the cognitive deficiencies caused by acute neuroinflammation. Regarding oxidative stress, there was an increase in catalase enzyme activity (CAT) in the group (SE + LPS) compared to the control groups (p < 0.05). As for the cognitive alterations, there were found in the (SE + LPS) group, diminishing the mnemonic hazard of the discriminative and social memories compared to the control groups (p < 0.05).ConclusionWe concluded, therefore, that the exercise performed prophylactically presents a protective effect capable of minimizing such mnemonic deficits and increasing catalase enzyme activity in rats that suffered a local neuroinflammatory process in the hippocampus.

Novel truncating variants in FGD1 detected in two Danish families with Aarskog-Scott syndrome and myopathic features.

Aarskog–Scott syndrome (AAS) is a developmental disorder, caused by disease‐causing hemizygous variants in the FGD1 gene. AAS is characterized by dysmorphic features, genital malformation, skeletal anomalies, and in some cases, intellectual disability and behavioral difficulties. Myopathy has only been reported once in two affected siblings diagnosed with AAS. Only few adult cases have been reported. This article reports four adults with AAS (three male cases and one female carrier) from two unrelated Danish families, all males presented with variable features suggestive of myopathy. All four carried novel hemizygous pathogenic variants in the FGD1 gene; one family presented with the c.2266dup, p.Cys756Leufs*19 variant while the c.527dup; p.Leu177Thrfs*40 variant was detected in the second family. All males had some mild myopathic symptoms or histological abnormalities. Case 1 had the most severe myopathic phenotype with prominent proximal muscular fatigue and exercise intolerance. In addition, he had multiple deletions of mtDNA and low respiratory chain activity. His younger nephew, case 3, had difficulties doing sports in his youth and had a mildly abnormal muscle biopsy and relatively decreased mitochondrial enzyme activity. The singular case from family 2 (case 4), had a mildly myopathic muscle biopsy, but no overt myopathic symptoms. Our findings suggest that myopathic involvement should be considered in AAS.

Impact of a Novel Training Approach on Hemodynamic and Vascular Profiles in Older Adults.

Exercise training beneficially moderates the effects of vascular aging. This study compared the efficacy of Peripheral Remodeling through Intermittent Muscular Exercise (PRIME), a novel training regimen, versus aerobic training on hemodynamic profiles in participants ≥70years at risk for losing functional independence. Seventy-five participants (52 females, age: 76 ± 5years) were assessed for hemodynamic and vascular function at baseline, after 4 weeks of either PRIME or aerobic training (Phase 1) and again after a further 8 weeks of aerobic and resistance training (Phase 2). Data were analyzed using 2 × 2 repeated-measures analysis of variance models on the change in each dependent variable. PRIME demonstrated reductions in brachial and aortic mean arterial pressure and diastolic blood pressure (p < .05) from baseline after Phase 1, which were sustained throughout Phase 2. Earlier and greater reductions in blood pressure following PRIME support the proposal that peripheral muscular training could beneficial for older individuals commencing an exercise program.

Lower-body muscular power and exercise tolerance predict susceptibility to enemy fire during a tactical combat movement simulation

This study examined if field-expedient physical fitness/performance assessments predicted performance during a simulated direct-fire engagement. Healthy subjects (n = 33, age = 25.7 ± 7.0 years) completed upper- and lower-body strength and power assessments and a 3-min all-out running test to determine critical velocity. Subjects completed a simulated direct-fire engagement that consisted of marksmanship with cognitive workload assessment and a fire-and-move drill (16 × 6-m sprints) while wearing a combat load. Susceptibility to enemy fire was modelled on average sprint duration during the fire-and-move drill. Stepwise linear regression identified predictors for the performance during the simulated direct-fire engagement. Critical velocity (β = −0.30, p < 0.01) and standing broad jump (β = −0.67, p < 0.001) predicted susceptibility to enemy fire (R 2 = 0.74, p < 0.001). All predictors demonstrated poor relationships with marksmanship accuracy and cognitive performance. These data demonstrate the importance of exercise tolerance and lower-body power during simulated direct-fire engagements and provide potential targets for interventions to monitor and enhance performance and support soldier survivability. Practitioner Summary: This study identified field-expedient physical fitness/performance predictors of a simulated direct-fire engagement which evaluated susceptibility to enemy fire, marksmanship, and cognitive performance. Our findings suggest that high-intensity exercise tolerance and lower-body power are key determinants of performance that predicted susceptibility to enemy fire.

Mind-body interventions involving a home-based component to improve functional fitness outcomes in adults: A scoping review

Introduction: Home-based physical activity has several advantages, considering the barriers that adults encounter to site-based studies (i.e., travel, time, weather). Mind-body interventions (MBIs) have the potential to not only improve cognitive and emotional regulation, but also affect functional fitness via gentle muscular movements and exercises. The purpose of this scoping review was to review the evidence for MBIs that incorporated a home-based component to improve functional fitness outcomes (FFO). Given the variety of populations studied, varied structure and style of the interventions, and various FFOs tested, a scoping review was identified as the most appropriate approach. Methods: For this scoping review, we searched the following databases: PubMed, Scopus, CINAHL, SportDiscus, PsycInfo and Cochrane Library using keywords related to MBIs with a home-based component, FFOs, and adults from inception to May 2021. Results: Of the 1,569 results identified, 14 studies met our inclusion criteria - 5 on Tai-chi, 5 on Yoga, 3 on Dance and 1 on Tai-chi and Yoga. Of these studies, 10 measured balance, 9 mobility, 4 fall risk, 4 strength and 2 flexibility. Study participants included healthy and clinical samples. The interventions ranged from 6 to 17 weeks with home exercise from 1 to 5 days/week. Home instruction was delivered via video (10), handouts (4), and live instruction (3). On-site MBIs were supplemented by home-based exercise instruction in 12 studies. Twelve of the 14 studies observed significant improvements in FFOs. Conclusion: Only 4 of the 14 studies included a fully-home based MBI. Although each one showed significant effects on their respective FFOs, more studies are needed to compare the efficacy of fully home-based MBIs to on-site MBIs. Future research on fully home-based MBIs is needed as they could offer advantages over in-person interventions in terms of fewer barriers, accessibility, cost-effectiveness and potential sustainability over time.

육군 착용형 로봇을 장착하기 위한 기능성 의복 설계 요소 조사

This study aims to derive the design requirements for functional clothing worn with military wearable robots using a survey of people with military experience. Specifically, 982 adult males with military and muscular exercise experience were surveyed for their demands for the clothing worn with wearable robots during military activities. The study showed that it is necessary to develop functional clothing worn inside robots suitable for frequent movements of soldiers to improve their comfort level of wearable robots. The surveyed soldiers indicated that they preferred the top and bottom clothing with high-pressure levels because the upper body felt fatigued during transportation, while both the upper and lower body got exhausted during marches. The survey of design requirements revealed that the participants preferred a top with long sleeves and a bottom with ankle-length leggings in color similar to current military uniforms. We conclude that it is important to design functional clothing worn inside wearable robots in different forms depending on frequent movements, e.g., with differentiated pressures and material placements.

Analysis of changes in the rat cardiovascular system under the action of lead intoxication and muscular exercise

Introduction. One of the risk factors for cardiovascular diseases is the toxic metal pollution of the industrial area and the environment. Lead is the most critical of toxic metals. In industrial conditions, the body’s exposure to harmful substances is often combined with muscular work of varying severity. It has not been studied enough how these combinations influence the development of pathological processes associated with harmful exposure. Materials and methods. The subchronic experiment was carried out on white outbred male rats for six weeks. Intoxication was simulated by repeated intraperitoneal injections of lead acetate three times a week. Running was chosen to model the muscle exercise at a 25 m/min speed for 10 minutes 5 days a week. We performed biochemical and electrocardiographic studies. Blood pressure parameters were recorded. Muscle contractility was studied on isolated multicellular preparations of the right ventricular myocardium in isometric and physiological contraction modes. The ratio of myosin heavy chains was determined by the polyacrylamide gel electrophoresis. The sliding velocity of reconstituted thin filaments on myosin using an in vitro motility assay. Results. Physical exercise under lead intoxication normalized the level of calcium and the angiotensin-converting enzyme activity in the blood serum, the voltage of the isoelectric line and the amplitude of the T wave on the electrocardiogram. The combined action of lead and physical exercise showed an increase in the creatinine kinase-MB level. We found that the effect of exercise under lead intoxication on myocardial contractility was ambiguous. The maximum isotonic shortening velocity in trabeculae was normalized, but the maximum rate of strength development in the isometric mode in the papillary muscles decreased to a greater extent than under lead intoxication. The maximum sliding velocity of reconstituted thin filaments and myosin and the heavy chain ratio was partly normalized. Conclusion. In general, muscle exercise attenuated the lead cardiotoxic effects.

제2형 당뇨병 환자의 혈당조절 영향요인 분석: 제7기 국민건강영양조사자료(2016∼2018) 이용

Purpose: This study examined factors influencing glycemic control among type 2 diabetes mellitus (T2DM) patients using data from the seventh Korea National Health and Nutrition Examination Survey. Methods: The subjects were 1,459 patients aged 30 years and older who with T2DM. The subjects were divided into three groups according to glycated hemoglobin A (HbA1c) values: good glycemic control group (good GCG, HbA1c<7%), insufficient GCG (7≤HbA1c< 8%), and poor GCG (8%≥HbA1c). Univariate multiple multinomial logistic regression was used. Results: The patients were distributed as follows: 52.7%, good GCG; 28.4%, insufficient GCG; and 18.9%, poor GCG. In the insufficient GCG, DM duration was a significant factor influencing glycemic control in T2DM. In the poor GCG, age, DM duration, hypertriglyceridemia, waist circumference and muscular exercise were significant factors influencing glycemic control in T2DM. Conclusion: Strategies for insufficient glycemic control should include intensive glucose control interventions for patients with a DM duration over 5 years. Strategies for poor glycemic control should include intensive glucose control interventions for younger age groups, those with a DM duration >1 year, and those with hypertriglyceridemia. In addition, nursing interventions for weight loss and muscular exercise are needed.

EFFECT OF LOWER LIMB PROXIMAL TO DISTAL MUSCLE IMBALANCE CORRECTION ON FUNCTIONAL PES PLANUS DEFORMITY IN YOUNG ADULTS

The pes planus deformity is seen more in adults. Pes planus or low foot medial longitudinal arch, contributes to lower extremity injury due to the muscular imbalance. This deformity causes proximal to distal muscle imbalance in lower limb. Effective correction of muscle imbalance is prime important in correction of pes planus. The purpose of the study was to find the effect of exercise in pes planus to correct the imbalance, improve the condition &amp; prevent the injuries along with the long-term effect of the pes planus deformity. To study and find the effect of lower limb proximal to distal muscle imbalance correction in pes planus deformity in young adults. 40 people with functional pes planus deformity were randomly assigned to a group that received the baseline treatment for the muscle imbalance along with the intrinsic muscle strengthening exercises (experimental group) or a group that received only intrinsic muscle strengthening exercises (control group). Each group received 6 weeks treatment. Statistical analysis were performed using paired t test and unpaired t test. In pre-intervention, there was no statistically significant difference seen with p values for the navicular drop test for the right leg and left leg 0.1127, 0.1504 respectively. Ink test p values for the right leg, left leg 0.4184, 0.8719 respectively. While on comparing the post-interventional values using the unpaired t test, revealed that there was extremely significant difference seen with p value for both legs the navicular drop test was 0.0001 and for the ink test (right leg=0.0008, left leg=0.0318). Our study reported that muscular imbalance corrective exercises along with the intrinsic muscle strengthening was more effective in improving the condition and muscle imbalance caused by the pes planus. So, muscular imbalance corrective exercises and intrinsic muscle strengthening exercises should be recommended to correct the deformity or prevent the abnormalities in people with functional pes planus.

Lower-Limb Electromyography Signal Analysis for the Bottom Group of Muscles Fitness Norm before and after Intensive Exercise

Muscular fitness is not only the ability of the body to adapt to work and the environment but also the operational ability of physical behavior. We speculated whether research could be conducted on the theory of muscular fitness and its qualitative/quantitative relationship based on muscular fitness and exercise physiology from the perspective of muscular endurance and muscular exploration. This study used standing long jumps as a standard metric for physical fitness to identify the bottom 20% groups. The experiment involved eight freshmen from the bottom 20% groups, and the pre-tests of the participants’ electromyography (EMG) signals under different exercise intensities were measured and after performing a set of intensive exercises for post-tests. The signal’ characteristics measured in time and frequency domains were analyzed to find the correlation between them and the participants’ muscular fitness. Weighted squats were chosen as the strength movements, which were separated into an exercise experiment and a force plate experiment. Both experiments included three different exercise intensities: 8 repetition maximum (RM), 18RM, and 28RM. The EMG signals were captured and analyzed in both time and the frequency domains. Finally, paired sample tests were performed to determine the difference of features under different exercise intensities. The comparison of readings before and after intensive exercises shows that, for the exercised experiment, a significant difference in the mean absolute (MAV), the variance of EMG (VAR), the root mean square value (RMS), and the average amplitude of change (AAC) was observed under 8RM. Under 18RM, MAV, VAR, and AAC showed a significant difference. In the force plate experiment, RMS, AAC, mean frequency (MNF), and median frequency (MDF) showed a statistically significant difference under the intensity of 18RM. As for intensity under 28RM, MAV, VAR, RMS, and AAC also showed significant difference.

Randomized controlled trial of moderate cardiovascular exercise for patients with drug-resistant epilepsy

ObjectiveThe primary research question of this study was whether a moderate cardiovascular exercise program can reduce seizure frequency in patients with focal drug-resistant epilepsy (DRE). The hypothesis is that cardiovascular fitness will reduce seizure frequency in persons with epilepsy (PWE). MethodsTwenty-eight patients were randomized into two groups; exercise or relaxation. The exercise group were given an ergometric bicycle sent to their home to be used for 150 min/week, 30 min/day for 5 days a week for the study period of 6 months. Participants in the relaxation group were given audio muscular relaxation exercises to be performed for 20 min at least five times per week for the study period of 6 months. Seizure counts and exercise/relaxation sessions were registered daily in a written diary. Both groups received monthly motivational telephone calls.Seizures, anxiety, and depression symptom ratings (Hospital Anxiety and Depression Scale (HADS)), health status ratings (RAND-36), aerobic capacity (estimated VO2max), self-efficacy for exercise (SEE), level of physical activity, and adverse events were measured at the baseline and after the 6 months of intervention. CONSORT guidelines were followed. ResultsTwenty-two patients completed the intervention. There were no significant changes in seizure frequency in either of the groups. Six months of moderate exercise did increase the level of physical activity and maximal oxygen uptake. SignificanceModerate exercise did not affect seizure frequency in this study. The patients in the exercise group did increase their estimated VO2max, which is an important indicator for health, without deterioration of seizure frequency. This was accomplished with only minimal support from a physiotherapist every month. To exercise at home at a moderate intensity level with regular support may therefore be an option for patients with epilepsy. The patients in the exercise group increased their level of physical activity significantly, which indicates that they were compliant to the treatment.

Current Perspectives Regarding The Effects of Muscular Exercise on Neurological Disorders: A Literature Review

Abstract Regular physical exercise is a well-known mechanism for preventing and treating several health conditions, from the general improvement of the overall health condition and the prevention of obesity and increasing the arterial collater-alization and blood flow to the upregulation of antiinflamma-tory and antioxidant signaling cascades. The beneficial effects of regular physical exercise are far-reaching and diverse. Chronic neurological disorders are considered a significant public health concern. Given the fact that the available treat-ment modalities in most neurological conditions are not fully curative and aiming primarily at improving the quality of life and the ability to cope, with a wide side effect profile of the available medications to the high cost of other available methods as electric stimulation devices, this highlight the importance of investigating the beneficial roles of regular physical exercise, both as a preventive and a curative tool, indifferent chronic neurological diseases. This short review of the literature highlights the recent research finding and mechanisms of the beneficial effects of exercise in different chronic neurological diseases.

Preparation of Rat Skeletal Muscle Homogenates for Nitrate and Nitrite Measurements.

Nitrate ions (NO3-) were once thought to be inert end products of nitric oxide (NO) metabolism. However, previous studies demonstrated that nitrate ions can be converted back to NO in mammals through a two-step reduction mechanism: nitrate being reduced to nitrite (NO2-) mostly by oral commensal bacteria, then nitrite being reduced to NO by several mechanisms including via heme- or molybdenum-containing proteins. This reductive nitrate pathway contributes to enhancing NO-mediated signaling pathways, particularly in the cardiovascular system and during muscular exercise. The levels of nitrate in the body before such utilization are determined by two different sources: endogenous NO oxidation and dietary nitrate intake, principally from plants. To elucidate the complex NO cycle in physiological circumstances, we have examined further the dynamics of its metabolites, nitrate and nitrite ions, which are relatively stable compared to NO. In previous studies skeletal muscle was identified as a major storage organ for nitrate ions in mammals, as well as a direct source of NO during exercise. Therefore, establishing a reliable methodology to measure nitrate and nitrite levels in skeletal muscle is important and should be helpful in extending its application to other tissue samples. This paper explains in detail the preparation of skeletal muscle samples, using three different homogenization methods, for nitrate and nitrite measurements and discusses important issues related to homogenization processes, including the size of the samples. Nitrate and nitrite concentrations have also been compared across four different muscle groups.

Muscle Work and Its Relationship with ACE and ACTN3 Polymorphisms Are Associated with the Improvement of Explosive Strength.

Background: The potential influence of genetics in athletic performance allows the search for genetic profiles associated with muscular work for the orientation of strength training and sports selection. The purpose of the study was to analyze four muscular exercises for effectiveness in improving explosive strength variables, associated to the genetics in Angiotensin Converting Enzyme (ACE) and α-actinin-3 (ACTN3) polymorphisms. Methods: A randomized controlled trial was conducted on a sample of 80 subjects allocated into four groups: concentric muscle work (CMW), eccentric muscle work (EMW), concentric-eccentric muscle (C-EMW) work and isometric muscular work (IMW), by block and gender randomization. Vertical jump, long jump, power jump, and speed were measured to study explosive strength. Genotypic frequencies of ACE (rs4646994) and ACTN3 (rs1815739) were obtained by polymerase chain reaction. Results: ACE gen showed significant improvements regarding the DD genotype in the Sargent test (p = 0.003) and sprint velocity test (p = 0.017). In the ACTN3 gene, the RR variable obtained improvement results with regard to RX and XX variables in long jump (p < 0.001), Sargent test (p < 0.001) and power jump (p = 0.004). Conclusions: The selected genes demonstrated an influence on the muscle work and the improvement in explosive strength variables with a decisive role regarding the type of muscle work performed.
