title: DILEMMA AND PATH SELECTION OF COLLEGE SPORTS RESOURCES INTO THE PUBLIC SERVICE SYSTEM OF NATIONAL FITNESS IN THE NEW ERA

description: ABSTRACT With the improvement of people's yearning for a healthy and beautiful life, national fitness has become a hot word in academic circles. Combining Data Envelopment Analysis (DEA) and the Tobit technology, this paper constructs the evaluation model of college sports resource efficiency based on the DEA Tobit model. Based on the establishment of the input-output index system of college sports resources, the model achieves the effect of accurate analysis on the allocation efficiency of university sports resources. Taking 10 universities in a city as experimental objects, the model is verified. The verification shows that the three efficiency indexes of STU University and IPE University in group M are all 1, which shows that the resource allocation is more reasonable; the comprehensive efficiency of Ju university is low, and the sports resources investment is excessive; in group n, except for the EU University, the efficiency of other colleges and universities is lower than the pass line. It can be concluded that there are problems such as excessive input of sports resources and low output rate in Colleges and universities of a city. Therefore, colleges and universities in a city should make full use of the existing resources, enhance their social sports guidance force, while improving the publicity of national fitness. This study has high reference significance for the path selection of national fitness integration in Colleges and Universities.

title: RESEARCH ON THE APPLICATION OF MUSIC-BASED PSYCHOLOGICAL ADJUSTMENT IN IMPROVING POSTGRADUATES’ MENTAL HEALTH

description: ABSTRACT At present, the mental health problem of postgraduates is still in the highest position, which directly affects the level of intellectual performance in social work. While mastering professional knowledge, it also requires postgraduates to have higher ideological and psychological qualities. On the basis of domestic and foreign research, this study takes the concept and advantages of music-based psychological adjustment as a theoretical basis and, through a large number of questionnaires, combined with the psychological characteristics of science and engineering postgraduates, we use the comparative method, the statistical analysis method and the experimental method to study the influence of music-based psychological adjustment on the mental health level of science and engineering postgraduates. It further illustrates that music promotes communication between man and nature. Music promotes communication between people and society. Music promotes communication between people and their inner world. Music can also build people’s faith and find the home of the soul. It emphasizes the influence of music on postgraduates’ emotions. The purpose of this is to build a reasonable and perfect music therapy system, so as to further enrich and strengthen the connotation and effect of mental health education in colleges and universities.

title: EFFECT OF EXTREME CONDITIONING TRAINING ON BODY PERCEPTION

description: ABSTRACT Introduction Extreme conditioning training (ECT) has become a popular method, characterized by a wide variety of exercises. For good technical performance, practitioners must have good perception of the different parts of the body; however, it is not known whether this perception differs between practitioners and non-practitioners of ECT. Objective To analyze the perception of body dimensions among subjects submitted to an ECT session. Methods Adult men were divided into TRAINED (n = 10) and UNTRAINED (n = 10). All subjects were submitted to a combination of high-effort multiarticular exercises for a set period of nine minutes (“the largest possible number of repetitions” [AMRAP]). For the procedure of marking the body pattern, the subjects were scored in terms of acromioclavicular joints, waist and trochanter. Results Regarding the general perception of body size, the TRAINED and UNTRAINED groups were classified as adequate for each stage. In the dimension of body segments, there was an overestimation of the shoulder region in both groups (TRAINED Pre = 105.2 ± 8.37; Post = 117.23 ± 22.11 [ES = 0.79]; 30 min = 101.34 ± 14.21 [ES = 0.34] and UNTRAINED Pre = 96.72 ± 12.79; Post = 99.47 ± 12.17 [ES = 0.22]; 30 min = 111.05 ± 11.06 [ES = 1.27]). The perception of the waist region improved significantly after training (TRAINED Pre = 114.11 ± 16.4; Post = 117.7 ± 20.16 [ES = 0.20]; 30 min = 104.59 ± 11.46 [ES = 0.68] and UNTRAINED Pre = 114.66 ± 9.88; Post = 104.64 ± 12.87; [ES = 0.88]; 30 min = 108.36 ± 12.32 [ES = 0.57]). Conclusion ECT can promote better perception of body dimensions. In addition, the assessment of body size in active, but untrained individuals showed a better body perception, albeit a transitory effect.

title: EMPIRICAL ANALYSIS AND INTERVENTION RESEARCH ON COLLEGE STUDENTS’ HEALTH INFLUENCE MECHANISM FROM THE PERSPECTIVE OF PUBLIC SPORTS

description: ABSTRACT The construction of public sports does not only improve the sports performance of college students, but also improves the health level of students. At present, the achievements of public sports construction in colleges and universities are not good, and the reasons for hindering the improvement of students’ physical health are more complex. In order to explore the problems existing in the construction of public sports in colleges and universities, this study used literature survey, the Delphi method, questionnaire survey and factor analysis to analyze the health impact mechanism of college students, and carried out intervention research according to analysis results. Factor analysis was used to extract the students’ factors, school factors, parents’ factors and social factors from the 30 influencing factors in the questionnaire and, through empirical analysis, it summed up the students’ health influence mechanism, such as learning pressure, physical education curriculum, family health attention and so on. In view of the main influencing factors, the targeted intervention, including improving the students’ and parents’ awareness of physical exercise and enhancing the load of physical education curriculum in colleges and universities is designed. Before and after the intervention, students’ sprint and long-distance running tests show that students’ physical fitness has been significantly improved, and the intervention results show that targeted intervention can promote the healthy development of college students. It is expected that this study can strengthen the level of public sports construction in colleges and universities, so as to improve students’ physical quality.

title: RELIABILITY OF A SIMPLE NOVEL FIELD TEST FOR THE MEASUREMENT OF PLANTAR FLEXOR MUSCLE STRENGTH

description: ABSTRACT Introduction When a person is in a standing position, the plantar flexor muscles are involved in most static and dynamic body movements. Objectives The aim of this study was to investigate the trial to trial and factorial reliability of measuring the contractile characteristics of PF muscles using a simple novel field test. Methods The sample consisted of 452 healthy subjects, 120 male and 332 female. The research was conducted by means of the trial to trial testing method, using isometric dynamometry performed in field conditions. ANOVA was used to estimate the differences among the trials, Cronbach’s alpha and interclass correlation to estimate the correlations among the trials, and principal component analysis to evaluate the contribution of each trial to overall variability. Results The main findings of this study are that trials differed significantly (p&lt;0.000) for maximal force (Fmax) and maximal rate of force development (RFDmax), indicating that the three procedural trials were necessary. The trials were highly correlated (Fmax, RFDmax, r&gt;0.9), proving that measuring was reliable, and the factorial analysis separated the second and third trials, the second trial accounting for most of the total variability. Conclusions The simple novel field test for the measurement of plantar flexor contractile characteristics recommended by this study proved to be as highly reliable as laboratory testing, but was easy to perform in conditions outside of scientific or diagnostic institutions, which greatly facilitates the work of scientists, coaches and professionals.

title: PSYCHOSOCIAL ASPECTS OF PHYSICAL ACTIVITY: DATA ON BRAZILIAN ADOLESCENTS

description: ABSTRACT Introduction Although the benefits of regular physical activity (PA) for adolescents are well-described in the literature, there is little evidence of the role of psychosocial aspects on levels of PA in this population. Objective To investigate the prevalence and sociodemographic factors associated with enjoyment of PA and preference for leisure-time activities in boys and girls. Methods A cross-sectional study, with 6529 adolescents (aged 15 to 19 years) enrolled in secondary education in public schools in the South of Brazil. Logistic regression was used to analyze the association between sociodemographic factors and the variables of interest, with data collection using a standardized questionnaire. Results Boys enjoyed (87.1%) and preferred (44.4%) PA more than girls (enjoyment: 79.2%; preference: 29.5%). Among the boys, enjoyment was associated with family income(OR3-5 wages=1.53; OR≥6 wages=1.62) and, among the girls, it was associated with age (OR19 years=0.28), occupational status (ORworkers=1.45), and income (OR3-5 wages=1.35). Preference was associated with age (OR19 years=2.48) and income (OR≥6 wages=0.70) among the boys and, among girls, it was associated with area of residence (ORrural=1.47) and occupation (ORworkers=1.31). Conclusion Boys (enjoyment: 87.1%; preference: 44.4%) had more positive attitudes toward PA than girls (enjoyment: 79.2%; preference: 29.5%), and some sociodemographic variables appear to be more closely associated with these attitudes than others. Enjoyment was associated with family income for boys, and with age, occupation and income for girls. Preference, in turn, was associated with age and family income for boys, and area of residence and occupational status for girls.

title: ASSOCIATION BETWEEN LEVELS OF SPORTS PARTICIPATION AND ORAL INJURIES AMONG COMBAT ATHLETES

description: ABSTRACT Introduction Oral injuries are common traumas in combat sports due to the aggressive nature of both offense and defense. Sports mouth guards are made to reduce the risk of traumatic face and jaw injuries and concussions during sports activities. Objective The objective of this study was to determine the prevalence of oral injuries in combat sports and to examine the association between participation levels and percentage of injury occurrence. Methods One hundred and eight participants (mean age: 22.42 ± 2.162 years) who were involved in sparring events were recruited. Data were collected using a questionnaire consisting of 22 questions about the demographic profile of the athletes, their injury experience and type of injuries sustained, awareness and use of mouth guards in sports activities. Descriptive analysis, Chi-square test, and one-way analysis of variance (ANOVA) were applied for data analysis. Results Almost 77% of participants had experienced oral injuries during sports activities and nearly 90% were aware that oral injuries can be reduced by using mouth guards. In addition, 52.7% of participants complained that the mouth guard is not comfortable to use during sports activities. Findings revealed a significant moderate association between levels of participation and number of oral injuries ( p = 0.013). One-way ANOVA showed a significant mean difference in the rate of oral injury for the four levels of participation groups F (3, 104) = 6.21, p = 0.011. Post-hoc comparisons using the Bonferroni test indicated a significant mean difference between university-state levels ( p = 0.033) and university-national levels ( p = 0.028). Conclusion This study revealed that higher levels of participation in sports have a higher risk of injury. It was also found that the discomfort of using a mouth guard can be reduced if the coaches make the athletes wear proper mouth guards that follow the recommended specifications. Level of evidence IIIb; Case control study.

title: EFFECTS OF BLOOD FLOW RESTRICTION IN LARGE AND SMALL MUSCLE GROUPS

description: ABSTRACT Introduction It is known that strength training brings improvements in health and sports performance by causing muscle hypertrophy and increased strength, as well as modifying some hemodynamic and physiological factors. Several strength training methodologies have been developed, one of which is vascular occlusion. There are few studies with large muscle groups due to poor adherence to the training style and the fact that vascular occlusion of large muscle groups is more difficult. Objective To verify and compare the hemodynamic effects of exercise with and without vascular occlusion in different muscle groups. Methods Quantitative crossover study, with cross-sectional and field procedures. The sample consisted of 10 physically active healthy male and female subjects between 18 and 30 years of age. With the cross-over design, all the volunteers participated in 3 groups: intervention with vascular occlusion, intervention without vascular occlusion and the control group. Results Overall, lactate and cholesterol remained elevated after 15 minutes of recovery and blood glucose and blood pressure did not vary among the groups. Conclusion Vascular occlusion training is an effective method for manipulating hemodynamic variables. Evidence level II; Clinical study.

title: FLUID BALANCE DURING TAEKWONDO TRAINING

description: ABSTRACT Introduction Dehydration has been described as one of the main factors of reduced performance in combat sports activities, leading to death in extreme cases. Objective To investigate the pre-training hydration status and changes in fluid homeostasis during two taekwondo training sessions. Methods Eighteen male college athletes (age 22.6 ± 3.37 years) were assessed. The study design aimed to reproduce the conditions of a 90-minute taekwondo training session, divided into three stages: a) warm-up exercises (20 min); b) poomsae (30 min) and c) technical training (40 min). The athletes had ad libitum water intake during training. To assess the hydration status we considered body mass (BM), the amount of liquid consumed and urine output, which enabled us to establish absolute and relative fluid loss in kg and percentage as well as the sweating rate. We also considered urine specific gravity (USG), urine color (U-COL), and subjective sensation of thirst (Sthirst) before and after the training session. Pre- and post-training results were compared separately in each session and between sessions. Results There was a significant difference (P&lt;0.05) in pre-training BM between the two days of training. There was a significant difference (P&lt;0.05) in the final BM on both days of the experiment. Most subjects had relative dehydration below 2%. A significant difference (P&lt;0.05) was recorded pre and post training for U-COL and Sthirst, with the highest rates obtained at the end of each session. Participants always started training at a low dehydration status (USG &gt;1,020g.ml-1). Conclusions The athletes tended to start the training sessions in dehydration status, which increases over the course of the training. Ad libitum water intake was not sufficient to balance fluid loss. Changes in fluid levels between sessions were similar.

title: SOCIOECONOMIC STATUS AND PHYSICAL ACTIVITY DURING ELEMENTARY SCHOOL STUDENT RECESS

description: ABSTRACT Introduction The association between socioeconomic status (SES) and the level of physical activity (PA) at school has not been studied at length. Objective To describe the association between SES and the intensity of physical activity during recess in elementary school children as well as the space dedicated to physical activity. Methods A total of 212 children (110 boys and 102 girls) who were enrolled in the fourth, fifth and sixth grade of elementary school at the time participated in this study. The subjects were divided into 4 levels according to the marginalization index (MI). The geographical location of the schools and the available area were calculated using Google Maps Pro (GMP) software.1 Physical activity level was measured using accelerometry.2 Comparisons of different levels of PA with respect to marginalization indices and sex were investigated using one-way analysis of variance. The association between health variables and PA was determined through the Pearson correlation coefficient. Results Results indicated that the level and intensity of PA during recess are associated with socioeconomic status and the social marginalization index, as well as sex, age, and infrastructure. Conclusion The higher the level of social marginalization, the lower the level of PA and the smaller the space dedicated to PA. Level of Evidence III; Comparative retrospective study.

title: COMPARISON OF METHODS FOR EVALUATING UPPER LIMB STRENGTH BY HAND-HELD DYNAMOMETRY

description: ABSTRACT Introduction The upper limbs are segments of the human body responsible for primary activities of daily life, and the muscles are essential structures for performing these activities. There have been few studies on intra- and inter-examiner reliability of the hand-held dynamometer (HHD) in healthy subjects, and none have been published that compare dynamometric evaluation methods in the main muscles in this segment. Objective Evaluate intra-examiner and inter-examiner assessment reliability of the hand-held dynamometry of upper limb muscles in healthy individuals, as well as comparing the assessment reliability between fixed and non-fixed methods. Methods Healthy subjects aged over 18 years were recruited for the study. The isometric contraction for ten muscle groups of the dominant upper limb was tested. For the fixed method, we used a system of suction cups, connected to the HHD by an inelastic belt. For the non-fixed method, the examiner supported the device by hand. The isometric contraction was sustained for three seconds. Each measurement was repeated three times, considering the highest value obtained. The reliability was calculated using the intraclass correlation coefficient (ICC). The dispersion between measurements was expressed by a Bland-Altman plot. Results The sample consisted of 25 volunteers, all right-handed. The intra-examiner ICC was 0.89-0.99 for the non-fixed method, and 0.43 to 0.85 for the fixed method. Inter-examiner reliability showed equivalent behavior. This study showed that evaluation of upper limb muscle strength using an isometric dynamometer has excellent intra-examiner and inter-examiner reliability. The supine position was chosen due to the need to propose a feasible protocol for clinical practice that could be replicated for the majority of publics and in different environments. The non-fixed method showed better reliability overall, demonstrating the feasibility of this tool without the need for adaptations, additional devices, or increased operating costs for this evaluation. Conclusion Comparison between the fixed and non-fixed HHD methods demonstrated superiority of the non-fixed method in terms of reliability.

title: PHYSICAL TRAINING IN ATHLETES: ANALYSIS OF CARDIAC AUTONOMIC MODULATION

description: ABSTRACT Introduction Cardiac autonomic modulation (CAM) is a result of the balance between the sympathetic and parasympathetic systems. This interaction results in heart rate variation (HRV), analyzed by specific electrocardiographic parameters. These parameters are modified by the practice of physical activity, indicating better cardiac conditioning. Objectives To evaluate the cardiac autonomic modulation of athletes of the XXVIII Ecological Walk at two separate times during their period of physical training. Also, to link the practice of physical activity with stress reduction in these individuals. Methods 24-hour Holter exams were performed at two times (before and after a 2-month period of non-standard physical training), and the results were analyzed using the software programs Epi-Info 7 and BioEstat 5.0. Inferential analysis was performed by the nonparametric Shapiro-Wilk test. Statistical significance was assigned to p values less than 0.05, with 95% confidence interval (95% CI). Results The sample was mostly male (n = 14; 77.78%), with a mean age of 49.55 years. No individual trained for less than 60 days; most (47.06%) trained for 151-200 days, with walking being the predominant modality (64.71%). No statistically significant difference was found in the parameters HRV pNN50 (p = 0.18), rMSSD (p = 0.14) or HF (p = 0.117) after the evaluated training period. Conclusions Participants who are longtime sportsmen and physically active showed parasympathetic saturation, therefore, they did not show significant changes in HRV. Also, low levels of stress were observed in those who practiced physical activity. Level of evidence II; Prognosis Study.

title: BLOCK SLOPE IS THE MAIN DETERMINANT OF BLOCK PHASE PERFORMANCE IN SWIMMING

description: ABSTRACT Introduction Swimming starts are an important component for decreasing the total race time, especially in short events. In this phase of swimming, the aim is to increase performance using many different techniques and starting platforms. Objectives The effects of height and slope of the starting block on kick-start performance were assessed in this study. Methods Six male competitive swimmers performed 24 kick-starts using four block settings: 65 cm & 75 cm flat and 65 cm & 75 cm sloped. Two-dimensional kinetic and three-dimensional kinematic data were analyzed, including average and maximum horizontal/vertical forces and impulses; reaction times; movement and block times; and take-off vertical/horizontal velocities. Two-way within-subject design ANOVAs were implemented to test the effects of block height and slope on the kinetic and kinematic variables. Results Block slope was the main factor affecting most of the dependent variables. Shorter block and movement times, greater average and maximum vertical forces, vertical impulse, and maximum horizontal force were found for the sloped settings. An inverse relationship was found between block height and 0-5 m times. Conclusion Based on the results, blocks with height of 75 cm and slope of 10° provided better results in swimmers’ performance in the block phase.
