During the COVID-19 lockdown, all the courses at Imam Abdulrahman Bin Faisal University (IAU) were delivered fully online, including field-training courses. Since there was no previous experience in offering field-training courses in a distance format, the current study aims to identify factors that could impact students’ behavioral intention to accept the e-training approach in teaching field training courses at IAU. In order to gather the data, the researchers designed a questionnaire based on the UTAUT model and they ensured the face, content, and construct validity of the questionnaire by sending it to five experts in the relevant field and by using exploratory factor analysis. Also, all the questionnaire’s items were reliable since the Cronbach’s alpha values were above 0.77 for all the items. A total of 397 participants provided valid responses. The result of this study indicated that Effort Expectancy (EE), Facilitating Condition (FC), Performance Expectancy (PE), and Social Influence (SI), respectively were the primary predictors for students’ intention to use e-training. These factors explained 32.1% of the variance in students’ behavioral intentions. As far as students’ gender is concerned, there were significant differences between students’ PE, FC, and SI. Based on these results, policymakers at IAU will have a clear image of the most essential factors that colleges should target to increase students’ acceptance of e-training.
Circadian rhythms, metabolism, and nutrition are closely linked, although the effects of meal timing on the human circadian system are poorly understood. The time factor biological of nature is an essential element for the functioning of cosmic systems. In the event of any defect, many problems come out as a result of this imbalance, and here came whether to change the timing of eating diets has to do with the occurrence of illness in the body and the emergence of diseases of this age such as obesity and diseases of the gastrointestinal tract (gallbladder - diseases of the colon, liver, and others). Hence the need to research the effect of timing, eating the three meals, and the body's system to resist disease. The study sample was withdrawn from Egyptian and foreign guests in hospitality establishments in Hurghada, Egypt with 300 forms. SPSS statistical program was used, and the research was focused on the body's sympathetic nervous system and its role in regulating the body processes related to metabolism. The timing of waking up and eating meals reached a set of findings and recommendations. The most important ones are the need to amend the healthy track of food and to increase the awareness of educational health, followed by hotels and resorts’ restaurants and room services offering those meals according to the client’s demand and the time they want to eat the meal. Therefore, it is necessary to direct the food operators in the hospitality establishments to prepare the food at the optimum time and to search for the modification of new food trends in line with the nature and the regularity of the diet to prevent diseases.
AIM: The purpose of this study was to verify the effect of a resistance training program for 8 weeks on IGF1, gene expression, and physical performance in male student-athletes. METHODS: The population of this study was 20 male students divided to two equal groups. The parameters estimated were IGF1, gene expression, and muscle strength testing. Blood was drawn to verify the concentration of the variables, using kits and Elisa method in addition to the PCR technique. RESULTS: The results revealed that a significant increase in IGF1, gene expression was different between students. Furthermore, muscle strength testing revealed significant changes. CONCLUSION: The results suggested that resistance training program may impact fitness and muscle strength as well the anabolic activity through IGF1 increase accompanied by varied gene expressions.
The CD34+ antigen is a single chain trans membrane glycoprotein, expressed on human hematopoietic stem and progenitor cells, endothelial progenitor cells, vascular endothelial cells, embryonic fibroblasts and some cells in fetal and adult nervous tissue. The antigen is absent in fully differentiated hematopoietic cells such as lymphocytes, monocytes and granulocytes, erythrocytes and platelets. Regular physical activity is related to lower rates of CVD, however the mechanisms underlying the benefits of exercise in the prevention of CVD are not fully clear. Exercise may improve the number (Laufs et al., 2005) and function (Hoetzer et al., 2007) of EPCS. The purpose of this study was to assess the effect of physical activity on the support and enhance the natural behavior of stem cell CD34+ in aerobic and anaerobic exercise bouts, also after an aerobic and anaerobic training programs and the effect on some physiological parameters. - Results showed that Vo2max increased in aerobic training program than anaerobic one, also in case of aerobic exercise bout compared to anaerobic one. - Lactate concentration was decreased in aerobic training program than anaerobic one, also in case of aerobic exercise bout compared to anaerobic one. - HB, RBCs, WBCs and hematocrit value was increased after aerobic and anaerobic training program and exercise bout. - CD34+ HPC counts were increased in peripheral blood of aerobic and anaerobic training program also in case of anaerobic exercise bout than aerobic one. CD34+ HPC counts are higher in athletes compared to control indicating adaptation induced exercise. Results: VO2 max was increased significantly in case of aerobic training program compared to anaerobic one (63±2.2 ml/kg/min) (55±2.1 ml/kg/min). Hematological values increased significantly in anaerobic program compared to aerobic, RBCs (5.5±0.3 and 4.8±0.2 Mil. /ul), WBCs (6.6±0.5 and 6.1±0.4 Thous/ul), HB (15.4±0.4 and 14.2±0.5 g/de) Hematocrit (4.6±1.2 and 4.4±1.1 %), CD34+ stem cells count increased significantly in case of anaerobic program than aerobic (259.6±21.65 and 131±14.63) and sedentary (173±24.11). These findings suggest that anaerobic training program provoke better adaptation to exercise and stem cell counts may differ between trained and sedentary Circulating immature cells are likely to be involved in angiogenesis and repair process, both mechanisms being associated with strenuous exercise, knowledge of the physiological of effects of training on stem cells might be of potential clinical use.
The current study set out to determine the effect of diving on several physiological variables and stem cells in commercial divers for various years. Twelve divers and six non-divers were divided into three groups: 11 non-divers (1st group), two divers with a diving history of 5-6 years (2nd group), and three divers with a diving history of 9-10 years (3rd group). Physiological measurements of pulse, blood pressure, dynamic breathing functions, stem cells CD34 + , and cortisol were performed before and after physical exertion during a day dive at a depth of 25-30 meters in the pressure room. The results showed a significant difference in pulse, blood pressure, stem cells, and cortisol, while no change in dynamic breathing functions after exertion. Further, diving for different years may positively affect biological changes of stem cells CD34 + in the adaptation process but may harm dynamic breathing functions. Therefore, periodic lung function evaluation should be encouraged to check for potential harm to divers. In our conclusion, diving for different years may have a positive effect on biological changes of stem cells CD34 + in the adaptation process, while a negative effect may be induced in a dynamic breathing function. Periodic lung function evaluation should be encouraged to monitor potential harm to the divers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
