OBJECTIVE: To investigate the efficacy of core strengthening on trunk balance in patients with subacute stroke. METHOD: Fifty-nine subacute hemiparetic stroke in-patients participated in this study. All patients were randomly assigned to one of two groups: the control group and the experimental group. Both groups received the same conventional physical therapies for 4 weeks. The experimental group received an additional core strengthening program (CSP). Korean mini-mental state examination (K-MMSE) and Korean Modified Barthel Index (K-MBI) were performed on admission. CSP was performed for 30 minutes a day, 3 days per week for 4 weeks. We selected nine exercises available for stroke patients, and divided them as three steps according to the degree of difficulty. Because of the muscle weakness in stroke patients, a physical therapist often helped them during exercise. Outcome measurement included trunk control test (TCT), trunk impairment scale (TIS), and Berg balance scale (BBS) and we compared both groups before and after the period of training. RESULTS: There were no significant differences in baseline general characteristics and initial values between the two groups. After rehabilitation therapy, both groups showed significant improvements in BBS, TIS, and TCT (p<0.05). Following 4 weeks of therapy, changes of BBS, TIS score in the experimental group were significantly higher than those of the control group (p<0.05). However, the change of TCT score was not significantly different. CONCLUSION: Analysis of different clinical parameters showed that better outcomes in BBS, TIS scores were achieved from CSP. This study suggests that CSP conducted for 4 weeks may be beneficial as a therapeutic technique for use in improvement of trunk balance in patients with subacute hemiparetic stroke.

INTRODUCTION

COVID-19 is a pandemic that shut down businesses and industries worldwide. The spread of the disease changed social behavior as residents around the world were obliged to endure lockdown and quarantine measures, reducing their physical activity.

To determine the level of physical activity before and during the pandemic among physicians.

A cross-sectional study was carried out on 422 qualified physicians of the Philippine General Hospital, University of the Philippines Manila. The data was obtained from a self-administered questionnaire.

Results of the study revealed a shift of lifestyle from physically active to sedentary in 42.4-57.11% of the respondents during the pandemic. There was no change between the activity levels at work before and during COVID while there was a change in the travel and recreational activities. The results also showed that significant factors including lack of energy, fear of injury, lack of skill, resources, social influences, support seeking activities, and positive alternatives affected their activity levels.

During the pandemic, overall physical activity level decreased. Similarly, factors that motivate health workers to be physically active or sedentary during the COVID-19 pandemic can affect their physical activity levels. Based on this study, the hospital can create guidelines to ensure physical activity among its doctors, especially during a pandemic.

The benefits of exercises and physical activities have been proven for all-cause mortality, cardiovascular morbidity and many illnesses. To workout safely, medical examination and exercise testing should be done prior to exercise. Cardiac disease and musculoskeletal problems should be ruled out by medical examination and test. The result of exercise testing is the basic data for exercise prescription because of wide range of fitness on the same age and sex. Cardiopulmonary endurance, muscle strength and endurance, flexibility and balance ability are the basic components of fitness measurement. Appropriate method to assess fitness among various methods can be used. Moderate aerobic exercise is recommended to be done more than 30minutes a day, 5 times a week. Recently 150 minutes of moderate exercise a week is being recommended. Vigorous aerobic exercise more than 20 minutes a day 3 times a week or 75 minutes a week is recommended. Muscle strengthening and endurance exercise is recommended to be done 2~3 times a week

BACKGROUND AND OBJECTIVES

Physical activity (PA) and fitness level are considered key factors in public health promotion, and as such, healthcare workers (HCW) need to be physically well because they are not only responsible for themselves, but of their clients as well. Therefore, we aim to determine the PA and health-related fitness (HRF) level of HCW in a tertiary hospital, disaggregated to age, sex, work assignments, and job tenure.

A cross-sectional research design was utilized to assess HCW from the administrative, medical, nursing, and paramedical cohorts. ALPHA-FIT Test Battery was used to assess cardiorespiratory fitness, muscular strength, lower extremity power and strength, upper body muscle endurance, balance, and body composition.

Our study concurred with the results of previous studies on HCW yielding lower PA levels compared with the general population. We tested 282 participants (administrative: 97; medical: 36; nursing: 55; paramedical: 94), mean age 37.4 years, 64.54% females, 52.13% perceived average health status. Ninety percent of the HCW had PA levels below the World Health Organization’s recommended levels. The ALPHA-FIT mean score per category revealed: one-legged stance, 2.67/3; figure-of-8 run, 2.45/3; shoulder-neck mobility, 4.58/5; modified push-up, 2.05/4; hand-grip strength, 2.5/5; jump and reach, 4/4; dynamic sit-up, 2.62/3; six-minute walk test, 475.38 meters covered. There were no significant differences in PA and HRF levels across cohorts except for modified sit-ups (p < 0.001) and figure-of-8 run (p = 0.012). The results showed significant inverse correlation between balance and shoulder-neck mobility and age (p < 0.001), and modified push ups (p = 0.004). Males had significantly higher sit-up scores (p < 0.001), one-legged stance scores (p = 0.001), and faster figure-of-8 run (p = 0.011), while females had better jump and reach scores (p < 0.001).

Physical activity levels of HCW did not meet the World Health Organization’s recommended PA levels. Healthcare professionals who are expected to be aware of the benefits of PA and HRF have shown low to midfit levels of grip strength, upper extremity endurance, core strength, and cardiorespiratory endurance. Information on PA and HRF may aid in policy making on employee wellness that could highly impact health service delivery.

Objective: Physical exercise can provide many health benefits in humans. Exercise-induced reactive oxygen species (ROS) formation and its downstream signaling cascades are reported to induce mitochondrial biogenesis in exercising tissues. Selenoprotein P (SELENOP) is the antioxidant hepatokine whose hypersecretion is associated with various metabolic diseases. It was reported to impair exercise-induced reactive oxygen species signaling and inhibit subsequent mitochondrial biogenesis in mice. However, the relationship between selenoprotein P and mitochondrial dynamics in humans has not yet been reported. While reduction of plasma selenoprotein P becomes an attractive therapeutic target for metabolic diseases, the role of regular exercise in this regard is still unknown. This study aimed to analyze the influence of regular habitual exercise on plasma selenoprotein P levels and its association with leucocyte mitochondrial DNA copy number in healthy young adults. Methodology: Plasma selenoprotein P levels and leucocyte mitochondrial DNA copy numbers were compared in 44 regularly exercising subjects and 44 non-exercising controls, and the correlation between the two parameters was analyzed. Plasma selenoprotein P levels were measured by Enzyme-linked Immunosorbent Assay, and leucocyte mitochondrial DNA copy numbers were measured using the qPCR method. Results: The regular-exercise group had lower plasma selenoprotein P levels with higher leucocyte mitochondrial DNA copy numbers than the non-exercise group. There was a tendency of negative correlation between the two variables in our studied population. Conclusion Regular habitual exercise has a beneficial effect on reducing plasma selenoprotein P levels while raising mitochondrial DNA copy numbers.

The present study aims to establish comprehensive evaluation models of physical fitness of the elderly based on machine learning, and provide an important basis to monitor the elderly's physique. Through stratified sampling, the elderly aged 60 years and above were selected from 10 communities in Nanchang City. The physical fitness of the elderly was measured by the comprehensive physical assessment scale based on our previous study. Fuzzy neural network (FNN), support vector machine (SVM) and random forest (RF) models for comprehensive physical evaluation of the elderly people in communities were constructed respectively. The accuracy, sensitivity and specificity of the comprehensive physical fitness evaluation models constructed by FNN, SVM and RF were above 0.85, 0.75 and 0.89, respectively, with the FNN model possessing the best prediction performance. FNN, RF and SVM models are valuable in the comprehensive evaluation and prediction of physical fitness, which can be used as tools to carry out physical evaluation of the elderly.
