Application of the Tabata system in the process of sectional work on judo wrestling in institutions of higher education of the Ministry of Internal Affairs of Ukraine

The authors of scientific and methodological works note that the sectional training in various sports (in particular, judo wrestling) is one of the effective ways to optimize the process of the training of the cadets in the higher education institutions of the Ministry of Internal Affairs of Ukraine. The search and application in the sectional training of the effective methods of the developing of the motor skills of the cadets is an important problem of the theory and methodology of the training in higher educational institutions with the specific learning conditions. The authors of the scientific and methodical works note that the "Tabata" training is currently one of the most effective and promising methods of training. The work is devoted to the study of the impact of the "Tabata" training on the level of the motor skills of the cadets in the process of judo wrestling training. A pedagogical experiment was organized during the work. Second-year cadets engaged in the judo wrestling section took part in the experiment. We studied the indicators of physical preparedness (level of endurance, strength and speed qualities) according to tests recommended by the Ministry of Internal Affairs. The improvement of the indicators of the physical preparedness of the cadets in the process of the "Tabata" training was greater than the improvement of the physical preparedness during traditional training.

The impact of the comprehensive use of sports games on the physical fitness of high school students

The results of experimental research on the effectiveness of the comprehensive use of sports games (volleyball, football, basketball, and handball) during extracurricular activities for high school students in physical education have been presented. The aim of the research was to determine the effectiveness of the extracurricular program based on the comprehensive use of sports games to improve the physical fitness of high school students. Research methods included analysis and generalization of data from scientific and methodological literature, pedagogical observations, pedagogical experiment, testing of general and special physical fitness, anthropometric methods of research, physiological methods of research, express assessment of physical health, and methods of mathematical statistics.
 The implementation of the experimental extracurricular program with volleyball games in general contributed to the improvement of overall physical fitness, including an increase in physical performance, development of physical qualities, a decrease in blood pressure, improvement of the general peripheral vascular resistance index, Robinson index, hypoxia index, Skibinski index, improvement of the functional state of the cardiovascular and respiratory systems, improvement of physical health indicators, and improvement of special physical fitness indicators. In high school boys in the experimental group, significant improvement in their physical fitness was recorded compared to boys in the control group. Statistically significant improvements were observed in the level of physical performance, general level of physical fitness (speed-strength, strength abilities, level of agility, endurance, and flexibility), special physical fitness indicators, functional state, functional fitness, and physical health indicators. The analysis of the results of the pedagogical experiment suggests a high potential for the proposed approach to improve the system of extracurricular activities in physical education in secondary education institutions.

Towards sustainable transparent flexible heaters: Integration of a BNNT interlayer using green solvent substitution

Processing materials in electronics with non-toxic, green solvents can provide environmental benefits while reducing manufacturing health and safety challenges. Unfortunately, green solvents are often unable to provide comparable solubilizing characteristics and present challenges in printing and film formation compared to conventional organic solvents. Therefore, green materials are often developed in parallel to their processing method for successful implementation. In this study, we report on the use of a polyvinyl butyral (PVB) and ethanol solution as a replacement for poly (3-hexylthiophene-2,5-diyl) (P3HT) and chloroform and its’ first demonstration in boron nitride nanotube (BNNT) thin film interlayers for improved thermal and mechanical performance in silver microgrid transparent heaters. Using PVB/ethanol led to comparable thin films of BNNT, achieving a clear tube network formation across the substrate surface and resulting in near identical optical transparency and surface energy measurements compared to the P3HT/chloroform system. Silver microgrids printed on BNNT-coated polyethylene terephthalate (PET) with PVB as dispersant exhibited a similar conductive performance to the microgrids printed on BNNT-coated PET with P3HT, providing the same level of mechanical endurance and maintaining thermal performance metrics upon applied voltage. The PVB and ethanol system presents an exemplary green material combination for the novel deposition of BNNT thin film interlayers for integration into transparent heaters.

Socio-Economic Development of Tibet in the 7th Five-Year Plan (1986–1990). Part 5

The fourth stage of the socio-economic development of Tibet (1979–1985) was characterized by the beginning of the transition of its planned economy to a market economy, taking into account the Tibetan characteristics (Russian-Chinese Research, 2022, No. 4). In 1983, the State Council of the People's Republic of China began work on drawing up the next seventh five-year plan for the country's socio-economic development for 1986–1990. The developers set a triune task: firstly, to create favorable conditions and maintain a balance between aggregate demand and supply. Secondly, to ensure stable economic growth. Third, continue to improve the quality of life of the people. The 7th Five-Year Plan has become a true "strength test" of the People's Republic of China (including the Tibet Autonomous Region): numerous challenges in the field of economy, politics, social relations, demanded from the authorities of all levels of wisdom, endurance, foresight and vigorous action. This has led the TAP to achieve higher economic performance than the PRC as a whole.

An Attempt to Develop a Model of Brain Waves Using Quantitative Electroencephalography with Closed Eyes in K1 Kickboxing Athletes-Initial Concept.

Brain injuries are a common problem in combat sports, especially in disciplines such as kickboxing. Kickboxing is a combat sport that has several variations of competition, with the most contact-oriented fights being carried out under the format of K-1 rules. While these sports require a high level of skill and physical endurance, frequent micro-traumas to the brain can have serious consequences for the health and well-being of athletes. According to studies, combat sports are one of the riskiest sports in terms of brain injuries. Among the sports disciplines with the highest number of brain injuries, boxing, mixed martial arts (MMA), and kickboxing are mentioned. The study was conducted on a group of 18 K-1 kickboxing athletes who demonstrate a high level of sports performance. The subjects were between the ages 18 and 28. QEEG (quantitative electroencephalogram) is a numeric spectral analysis of the EEG record, where the data is digitally coded and statistically analysed using the Fourier transform algorithm. Each examination of one person lasts about 10 min with closed eyes. The wave amplitude and power for specific frequencies (Delta, Theta, Alpha, Sensorimotor Rhythm (SMR), Beta 1, and Beta2) were analysed using 9 leads. High values were shown in the Alpha frequency for central leads, SMR in the Frontal 4 (F4 lead), Beta 1 in leads F4 and Parietal 3 (P3), and Beta2 in all leads. The high activity of brainwaves such as SMR, Beta and Alpha can have a negative effect on the athletic performance of kickboxing athletes by affecting focus, stress, anxiety, and concentration. Therefore, it is important for athletes to monitor their brainwave activity and use appropriate training strategies to achieve optimal results.

Massage Therapy May Help Pain and Endurance Performance in Modern Pentathlon Athletes with Plantar Fasciitis.

Plantar fasciitis (PF) is common among both sports and inactive individuals and several treatment approaches are available. There is no study that examines the effect of massage on PF in multi-discipline athletes such as modern pentathletes. This study evaluated the effectiveness of massage on modern pentathletes suffering from PF. Twelve male athletes between the ages of 18 and 25 who had a history of plantar fasciitis pain and participated in modern pentathlon sports took part in the study. Every athlete received a 15-minute deep friction massage (DFM) between 13:00 and 17:00 on each day of the week for 15 days. Before and after the massage, all athletes' pain and endurance levels were measured. For pain assessments, pressure pain algometry was utilised, and for endurance evaluations, the yo-yo intermittent endurance test was utilised. Athletes participating in the study before (3.5 (2-5)) and after (7 (6-8)) pain average measurements and before massage (830±60) and after (1498.33±52.88) endurance average measurements pretest-post It was determined that there was a statistically significant difference between test values. According to the study, massage, an alternative therapeutic strategy, can be used to address the PF issue. To increase the accuracy of the findings and to assert that massage is the definitive treatment for PF, it is proposed that other sample groups with PF diagnoses be included in the studies, or that the treatment time for a single sample group be extended.

Cardiovascular endurance and psychosocial health predict short- and long-term BMI-SDS reduction: results from the CHILT III program

This longitudinal study analyzes data from the Children’s Health Interventional Trial (CHILT) III, an 11-month juvenile multicomponent weight management program. The objective is to identify predictors of changes in body mass index standard deviation scores (BMI-SDS), so as to further enable the advancement of existing interventions with sustained impact. This study’s sample consists of 237 children and adolescents with obesity (8–17 years, 54% girls) participating in the CHILT III program between 2003 and 2021. Anthropometrics, demographics, relative cardiovascular endurance (W/kg), and psychosocial health (i.e., physical self-concept and self-worth) were assessed at program entry (t1), end (t2), and one-year follow-up (t3; n = 83). From t1 to t2, the mean BMI-SDS was reduced by −0.16 ± 0.26 units (p < 0.001). Media use and cardiovascular endurance at baseline and improvements in endurance and self-worth over the course of the program predicted changes in BMI-SDS (adj. R2 = 0.22, p < 0.001). From t2 to t3, mean BMI-SDS increased (M = 0.09 pm 0.29, p = 0.005). Changes in BMI-SDS from t2 to t3 were associated with parental education, improvements in cardiovascular endurance and physical self-concept, and BMI-SDS, media use, physical self-concept, and endurance level at program end (adj. R2 = 0.39, p < 0.001). Conclusions: This study highlights the need for comprehensive, sustainable weight management approaches, in order to sustain the initial treatment benefits. In this context, improvements in cardiovascular endurance and psychosocial health could be essential strategies to pursue in practice, as they significantly predicted reductions in BMI-SDS – both pre- to post-intervention and at follow-up.Trial registration: DRKS00026785; date of registration: 13.10.202, retrospectively registered.What is Known:• Childhood obesity is associated with the onset of noncommunicable diseases, many of which are likely to carry into adulthood. Thus, effective weight management strategies for affected children and their families are vital. However, achieving lasting positive health outcomes with multidisciplinary weight management programs remains challenging.What is New:• According to this study, short- and longer-term BMI-SDS reductions are associated to cardiovascular endurance and psychosocial health. These factors should therefore be given even greater consideration in weight management strategies, as they may be important not only in themselves but also for long-term weight loss (maintenance).

Validity and sensitivity of field tests' heart-rate recovery assessment in recreational football players.

We aimed at examining the criterion validity and sensitivity of heart-rate recovery (HRRec) in profiling cardiorespiratory fitness in male recreational football players in the untrained and trained status, using endurance field-tests. Thirty-two male untrained subjects (age 40 ± 6 years, VO2max 41.7 ± 5.7 ml·kg-1·min-1, body mass 82.7 ± 9.8 kg, stature 173.3 ± 7.4 cm) participated in a 12-week (2‒3 sessions per week) recreational football intervention and were tested pre- and post-intervention (i.e. untrained and trained status). The participants performed three intermittent field tests for aerobic performance assessment, namely Yo-Yo intermittent endurance level 1 (YYIE1) and level 2 (YYIE2) tests, and Yo-Yo intermittent recovery level 1 (YYIR1) test. VO2max was assessed by performing a progressive maximal treadmill test (TT) and maximal HR (HRmax) determined as the maximal value across the testing conditions (i.e., Yo-Yo intermittent tests or TT). HRRec was calculated as the difference between Yo-Yo tests' HRpeak or HRmax and HR at 30 s (HR30), 60 s (HR60) and 120 s (HR120) and considered as beats·min-1 (absolute) and as % of tests' HRpeak or HRmax values. Significant post-intervention improvements (p<0.0001) were shown in VO2max (8.6%) and Yo-Yo tests performance (23-35%). Trivial to small (p>0.05) associations were found between VO2max and HRRec (r = -0.05-0.27, p>0.05) across the Yo-Yo tests, and training status either expressed as percentage of HRpeak or HRmax. The results of this study do not support the use of field-test derived HRRec to track cardiorespiratory fitness and training status in adult male recreational football players.

Multicomponent recreational team handball training improves global health status in postmenopausal women at the long term – A randomised controlled trial

ABSTRACT We studied the long-term effects of a multicomponent exercise training protocol (recreational team handball training, RTH) on global health status in inactive postmenopausal women. Participants (n = 45; age 65 ± 6 years, stature 157 ± 6 cm, body mass 66.2 ± 9.4 kg, fat mass 41.4 ± 5.5%, VO2peak 25.7 ± 3.6 mL/min/kg) were randomised into a control group (CG; n = 14) and a multicomponent exercise training group (EXG; n = 31, performing two to three weekly 60-min RTH sessions). Attendance was 2.0 ± 0.4 sessions/week (first 16 weeks) and 1.4 ± 0.5 (following 20 weeks) and mean heart rate (HR) loading was 77 and 79% of maximal HR (p = .002) for the first 16 and the following 20 weeks, respectively. Cardiovascular, bone, metabolic health, body composition and physical fitness markers were evaluated at baseline, and after 16 and 36 weeks. An interaction (p ≤ .046) was shown for the 2-h oral glucose tolerance test, HDL, Yo-Yo intermittent endurance level 1 test (YYIE1) and knee strength, in favour of EXG. At 36 weeks, YYIE1 and knee strength were higher (p ≤ .038) for EXG vs CG. Also, within-group improvements (p ≤ .043) were observed after 36 weeks for EXG in VO2peak, lumbar spine bone mineral density, lumbar spine bone mineral content, P1NP, osteocalcin, total cholesterol, HDL, LDL, body mass, android fat mass, YYIE1, knee strength, handgrip strength and postural balance. At 36 comparatively to 16 weeks, EXG showed an increase (p ≤ .036) in fasting blood glucose, HDL, knee strength and handgrip strength, and a decrease (p ≤ .025) in LDL. Collectively, this multicomponent exercise training (RTH) induces beneficial changes in global health status in postmenopausal women. Highlights We evaluated the long-term effects of a recreational team handball-based multicomponent training on broad-spectrum health and physical fitness markers of inactive postmenopausal women. Improvements in VO2peak and aerobic performance achieved after 16 weeks of training were maintained at 36 weeks. The 20-week extension of the training intervention resulted in further improvements in lipid profile markers and physical fitness variables. Recreational team handball could be suggested as an effective and safe strategy to counteract postmenopausal health-related constrains.

A comparative analysis of the effect of post production treatments and layer thickness on tensile and impact properties of additively manufactured polymers

Abstract In recent years, additive manufacturing (AM) technologies have become greatly popular in the polymer, metal, and composite industries because of the capability for rapid prototyping, and appropriateness for the production of complex shapes. In this study, a comprehensive comparative analysis focusing on the influence of post-processing types (heat treatment and water absorption) on tensile and impact responses was carried out on 3D printed PETG, PLA, and ABS. In addition, layer thickness levels (0.2, 0.3, and 0.4 mm) were selected as a major production parameter and their effect on mechanical properties was combined with post-processing type for the first time. The results showed that both tensile and impact resistance of the printed polymers increased thanks to the heat treatment. The highest tensile strength was measured for heat-treated PLA, while the peak impact endurance level was reached for heat-treated PETG. Also, water absorption caused a mass increment in all samples and induced higher tensile elongation values. Decreasing layer thickness had a positive effect on tensile features, but impact strength values dropped. On the other hand, all samples were subjected to macro and micro failure analyses to understand the deformation mechanism. These inspections indicated that for impact samples straight crack lines converted to zigzag style separation lines after the heat treatment. As for the tensile samples, the exact location of the main damage zone altered with the production stability, the water absorption capacity of the polymer, and the thermal diffusion ability of the filament.

Investigation of the effect of courage behaviors on endurance levels of canoe athletes

Background and Study Aim. Courage in sports is a concept that has attracted a lot of attention in recent years. It is very important for the athletes to reveal their psychological performance as well as their physical and technical skills during competition and or training times. In this context, this research is important in terms of revealing the mental endurance and courage levels of canoe athletes who struggle not only with their competitors but also with natural conditions.&#x0D; Material and Methods. The sample of the research consists of 163 volunteer canoe athletes selected by simple random sampling method. In order to collect the necessary data in the research, the “Courage in Sports Scale” was used. The scale consists of the sub-dimensions of 'competence', 'determination', 'aggression', 'taking the risk' and 'being self-sacrificing'. T-test and ANOVA test were used in the analysis of the data. Statistically, the error level was accepted as p&lt;.05 and the significance level was Alpha (α).&#x0D; Results. In the study, it was determined that the perception scores of the athlete students between the courage scale components were close to each other. No statistically significant results were found in all sub-dimensions according to gender and weekly training duration variables. According to the age variable: a significant result was determined in the dimensions of determination and assertiveness, and in the dimensions of stability according to the variable of doing sports. According to the education variable, it was determined that there was no significant difference in the risk-taking sub-dimension. There were significant differences in the other sub-dimensions.&#x0D; Conclusions. Without ignoring the acquisition of skills such as courage, it should be included in education and training programs from an early age and supported by sports training. Courage issues should be included in the training programs of educators (coaching training courses, seminars, etc.) and their importance should be emphasized.

Effect of muscle fatigue of the thoracic erector spinae on neuromuscular control when performing the upper extremity functional tasks in people with adolescent idiopathic scoliosis.

Adolescent idiopathic scoliosis (AIS) disrupts spinal alignment and increases the intrinsic demand for active stabilization to maintain postural stability. Understanding the paraspinal muscle fatigability and its effects on spinal alignment and kinematics informs the importance of paraspinal muscle endurance for postural stability. This study aims to investigate the effects of fatigue of thoracic erector spinae on the spinal muscle activity and spinal kinematics in individuals with scoliosis. Spinal muscle activity, posture and mobility measured by electromyography and surface tomography were compared between 15 participants with scoliosis and 15 age- and gender-matched healthy controls during unilateral shoulder flexion and abduction with and without holding a 2-kg weight and performed before and after a fatigue task (prone isometric chest raise). No between-groups difference was found for the spinal extensor endurance. Erector spinae activity at the convex side of AIS group was significantly higher than that at their concave side and than that of healthy controls during shoulder elevations, regardless of the fatigue status. Significant decreases in translational and rotational mobility were found at convex side of AIS group during weighted abduction tasks after fatigue. In contrast, a significant increase in rotational mobility was demonstrated at convex side of AIS participants during weighted flexion tasks after fatigue. Our results revealed a comparable level of spinal extensor endurance between individuals with or without AIS. The increase in muscle activation post-fatigue provides no additional active postural stability but may increase the risk of back pain over the convex side in individuals with scoliosis. Findings highlight imbalances in muscles and the potential implications in optimising neuromuscular activation and endurance capacity in the rehabilitation for AIS patients. Future research is needed to investigate if endurance training of the convex-sided back extensors could optimize the impaired neuromuscular control in the AIS patients.

The Effect of Health-Saving Educational Technologies on Development of Natural Abilities of Schoolchildren

Health saving-based educational technologies aim to provide a combination of children's needs, motivations, knowledge, optimal health level and normal physical development. In this study, the effect of the health-saving educational technologies program applied to secondary school students in increasing their physical fitness, self-efficacy in sports and mental endurance in reducing negative nutritional behaviors was examined. In the study, experimental procedures were carried out according to the 2x2 control group, pretest and posttest trial model. Experimental applications of the study lasted for 10 weeks, with 33 experimental and 33 control group students. During this period, the health-saving educational technologies program was applied in the experimental group; on the other hand, no application was made in the control group. Before and after the experimental procedure, pretests and posttests were applied to the experimental and control groups (Physical Fitness Test, Sports Self-Efficacy Scale, Negative Eating Behavior Scale and Mental Endurance Scale). According to the research findings, the students in the experimental group, who applied the health-saving educational technologies program, achieved higher levels of physical fitness, sports self-efficacy and mental endurance than their peers in the control group. It has also been found that the health-saving educational technologies program is effective in reducing negative eating behaviors.

No changes in the abundance of selected fecal bacteria during increased carbohydrates consumption period associated with the racing season in amateur road cyclists.

Cyclists often use high-carbohydrate, low-fiber diets to optimize the glycogen stores and to avoid the gastrointestinal distress during both, the trainings and the competitions. The impact of such dietary changes on gut microbiota is not fully known. We assessed the abundances of Faecalibacterium prausnitzii, Akkermansia muciniphila, Bifidobacterium spp., and Bacteroides spp. and the fecal pH in 14 amateur cyclists during the racing season. Eleven healthy men formed the control group. Despite significant differences in the diet composition and physical endurance levels of amateur cyclists before the competition season (1st term) and control group (carbohydrates: 52.2% ± 4.9% vs 41.9% ± 6.6%; VO2max: 56.1 ± 6.0 vs 39.7 ± 7.7; p<0.01; respectively), we did not observe any significant differences in studied gut bacteria abundances or fecal pH between the groups. Although the cyclists' carbohydrates consumption (2nd term) have increased throughout the season (4.48 g/kg b.w. ± 1.56 vs 5.18 g/kg b.w. ± 1.99; p<0.05), the studied gut bacteria counts and fecal pH remained unchanged. It seems that the amateur cyclists' diet with increased carbohydrates intake does not alter the gut microbiota, but further research is needed to assess the potential impact of even higher carbohydrates consumption (over 6 g/kg b.w.).

Mobile Gamers versus Non-gamer students’ endurance levels via Beep and 3-minute step test

Background and Study Aim. College students’ activity levels are considerably affected by mobile gaming, according to multiple studies. There have, however, been no studies done to date comparing gamers and non-gamers in terms of their levels of endurance. This present study employed beep and 3-minute step tests to compare mobile gamers’ and non-gamers endurance levels. In addition, the difference between demographic variables such as age, gender, and BMI and participants’ aerobic capacity is a major area of study. Material and Methods. Students at the City College of Angeles in the Philippines were selected using the Judgement Sampling Technique to take part in the research. Students who participated in the study are enrolled in the 1st Semester of the Academic year 2022-2023. A survey questionnaire consisting of four sections were utilized to obtain information from the respondents. Age, gender, body mass index (BMI), and an endurance test are all part of the personal profile. Both the beep test and the 3-minute step test were administered to the participants. Results from the participants’ personal profiles, BMIs, and endurance tests were summarized using descriptive statistics like frequency (f) and percentage (%). The Paired T-Test was also used to find out if there was a significant difference in the participants’ endurance between mobile gamers and non-gamers. Finally, the individuals’ age, gender, and Body Mass Index (BMI) were validated with their endurance levels by performing Independent Samples T-Test and One-way ANOVA. Results. Beep and 3-minute step tests showed that gamers and non-gamers have very different levels of endurance, with the latter group displaying much more stamina than the former. It was also shown that among the three factors studied, gender was the only one with a relationship to endurance. Conclusions. The study did not take into account factors like health history including nutrition, diet, sleep pattern, lifestyle, health issues, and endurance level on other types of measures. Conducting an inquiry similar to the one that was done, but also taking into account the other variables indicated, is a highly suggested course. Several findings are established, and numerous suggestions for further research, as well as policy and educational applications, are provided.

The molecular athlete: exercise physiology from mechanisms to medals.

Human skeletal muscle demonstrates remarkable plasticity, adapting to numerous external stimuli including the habitual level of contractile loading. Accordingly, muscle function and exercise capacity encompass a broad spectrum, from inactive individuals with low levels of endurance and strength to elite athletes who produce prodigious performances underpinned by pleiotropic training-induced muscular adaptations. Our current understanding of the signal integration, interpretation, and output coordination of the cellular and molecular mechanisms that govern muscle plasticity across this continuum is incomplete. As such, training methods and their application to elite athletes largely rely on a "trial-and-error" approach, with the experience and practices of successful coaches and athletes often providing the bases for "post hoc" scientific enquiry and research. This review provides a synopsis of the morphological and functional changes along with the molecular mechanisms underlying exercise adaptation to endurance- and resistance-based training. These traits are placed in the context of innate genetic and interindividual differences in exercise capacity and performance, with special consideration given to aging athletes. Collectively, we provide a comprehensive overview of skeletal muscle plasticity in response to different modes of exercise and how such adaptations translate from "molecules to medals."

Training overlap and its impact to developing the special endurance for young football players

The importance of the research lies in adopting the method of overlapping training to develop special endurance as one of the most important special requirements for soccer players, because raising the level of special endurance, which is mainly linked to the degree of functional adaptation, is reflected in improving the level of physical, skill, tactical and psychological achievement effectively throughout the time of the match, and this has an impact on improving the level of achievement for the player and the team alike. As for the research problem, it was represented in the low level of special endurance for the players, which appears in the clear decline in the level of performance, especially in the last third of the match, due to the weak level of special endurance for the players, which leads to slow recovery and early fatigue, lack of concentration and low level of overall performance (physical, technical, tactical, and psychological), which appears through random play, scattering of balls, frequent tackles, slow defensive and offensive activities, as well as the inability to implement modern tactics, which depend heavily on the application of the concept of comprehensiveness in the performance of tactical duties. While the objectives of the research were to develop a training curriculum in the style of overlapping training to develop the special endurance of football players, as well as to identify the impact of the training curriculum in developing the special endurance of football players. Wasit province, which numbered (18) players. The most important conclusions were: The development that occurred for the research group in the level of endurance as a result of the special effect of the vocabulary of the training curriculum in the overlap style. The researchers also recommend the need to adopt the training overlap method and the components of the training load by the trainers when training levels corresponding to the level of the research sample.

Neutrosophic MCDM Methodology to Select Best Industrial Arc Welding Robot

Industrial robots have made it possible for industrial companies to make goods of a good quality at lower costs. As a result, industrial robots are an integral component of sophisticated manufacturing systems. Industrial robots may be programmed to do a wide variety of tasks, including welding, painting, construction, and debugging. All of the elements are completed with an exceptional level of endurance, swiftness, and accuracy. The efficiency of industrial robots is governed by a number of different factors, some of which are in direct opposition to one another; for a strong choice approach, all of these criteria must be examined concurrently. For the purpose of selecting an industrial robot for the arc soldering process, a straightforward multi-criteria decision-making (MCDM) approach that is VIKOR method will be described in this research. The VIKOR method used to rank the robots. The results of the VIKOR methodology are provided here in the form of a priority of rating. The findings demonstrated that the MCDM strategies are highly helpful when selecting robots to utilize.
