Evaluating the Effect of 12 Weeks Football Training on the Posture of Young Male Basketball Players

Posture is the most healthy and correct placement of each region in the body when compared to the whole body. The predominantly use of one side of the body disrupts the posture. A bad posture changes the center of gravity of the body and causes chronic skeletal and muscle soreness. It is aimed to determine whether there is a rehabilitative effect of football training that does not require the use of dominant arms on posture asymmetries which may occur in the basketball which requires the use of dominant arm and leg in the study.15 male basketball players who played basketball for an average of 8 years with a mean age of 21.7 ± 1.5 years participated as volunteers. Postures of the subjects were measured with PostureScreen Mobile® before and after 12 week football trainings with lateral and anteriorly taken photographs. SPSS 22 was used program for statistical analysis. While analyzing of data Wilcoxon Test method was used and it is determined as significance level was p<0.05.After 12 weeks of football training, statistically significant differences were found in measurements taken from the anterior and lateral positions on the head, shoulder, ribcage, hip, and knee measured tilts and shifts. Estimated average head weight decreased depending on the posture of the cervical vertebrae and a significant difference was detected. Postures of subjects came close to the correct posture.Basketball is an acycle sport branch that requires the use of muscles on the dominant side. It creates an asymmetric position on the athlete due to this feature; causes shifting and tilts. In order to eliminate postural disorders that occur, the effectiveness of football training that does not require to use of the dominant side of the body has been demonstrated.

ABSTRACT Toilet training is an effort to train children to be able to control and urinate (BAK) and defecate (BAB). Toilet training is one of the main tasks of children at toddler age. Toilet training is one of the main tasks of children in toddler age which is very important to be done to create independence in children in controlling BAK and BAB and children know the parts of the body and their functions. Data in 2012 shows that ± 60% of parents do not teach toilet training to children from an early age. The aim of the study was to find out the effectiveness of toilet training education on maternal behavior and toilet skills in toddler age training (18-36 months). The study was conducted in July-August 2018. This type of quantitative research used the design of the Quasy pretest and posttest experiment with non-equivalent control group design. Samples were 36 mothers and 36 children with purposive sampling technique. Data analysis used Paired t test, Wilcoxon test, Man-Whitney test an Independent t test. The results showed that toilet training education through lecture methods, modules and maze games was more effective than toilet training education through lecture and leaflet methods on children's knowledge and abilities. Conversely, for the role of mothers in supervision there is no significant difference in effectiveness. Health education is recommended in health promotion programs to increase maternal knowledge, the role of mothers and the ability of toilet training children independently.

AbstractEvidence acquisition, interpretation and preservation are essential parts of forensic case work that make a standardized documentation process fundamental. The most commonly used method for the documentation and interpretation of superficial wounds is a combination of two modalities: two-dimensional (2D) photography for evidence preservation and real-life examination for wound analysis. As technologies continue to develop, 2D photography is being enhanced with three-dimensional (3D) documentation technology. In our study, we compared the real-life examination of superficial wounds using four different technical documentation and visualization methods.To test the different methods, a mannequin was equipped with several injury stickers, and then the different methods were applied. A total of 42 artificial injury stickers were documented in regard to orientation, form, color, size, wound borders, wound corners and suspected mechanism of injury for the injury mechanism. As the gold standard, superficial wounds were visually examined by two board-certified forensic pathologists directly on the mannequin. These results were compared to an examination using standard 2D forensic photography; 2D photography using the multicamera system Botscan©, which included predefined viewing positions all around the body; and 3D photogrammetric reconstruction based on images visualized both on screen and in a virtual reality (VR) using a head-mounted display (HMD).The results of the gold standard examination showed that the two forensic pathologists had an inter-reader agreement ranging from 69% for the orientation and 11% for the size of the wounds. A substantial portion of the direct visual documentation showed only a partial overlap, especially for the items of size and color, thereby prohibiting the statistical comparison of these two items. A forest plot analysis of the remaining six items showed no significant difference between the methods. We found that among the forensic pathologists, there was high variability regarding the vocabulary used for the description of wound morphology, which complicated the exact comparison of the two documentations of the same wound.There were no significant differences for any of the four methods compared to the gold standard, thereby challenging the role of real-life examination and 2D photography as the most reliable documentation approaches. Further studies with real injuries are necessary to support our evaluation that technical examination methods involving multicamera systems and 3D visualization for whole-body examination might be a valid alternative in future forensic documentation.

Body Balance

Background: The aim of the study is to assess the body balance and podological parameters and body composition of young footballers in the context of the control of football training. Methods: The study examined the distribution of the pressure of the part of the foot on the ground, the arch of the foot, and the analysis of the body composition of the boys. The pressure center for both feet and the whole body was also examined. The study involved 90 youth footballers from Olsztyn and Barczewo in three age groups: 8–10 years, 11–13 years old, and 14–16 years. The study used the Inbody 270 body composition analyzer and the EPSR1, a mat that measures the pressure distribution of the feet on the ground. Results: The results showed statistically significant differences in almost every case for each area of the foot between the groups of the examined boys. The most significant differences were observed for the metatarsal area and the left heel. In the case of stabilization of the whole body, statistically significant differences were noted between all study groups. In the case of the body composition parameters, in the examined boys, a coherent direction of changes was noticed for most of them. The relationships and correlations between the examined parameters were also investigated. The significance level in the study was set at p < 0.05. Conclusions: Under the training rigor, a statistically significant increase in stability was observed with age. The total length of the longitudinal arch of both feet of the examined boys showed a tendency to flatten in direct proportion to the age of the examined boys. Mean values of the body composition parameters reflect changes with the ontogenetic development, basic somatic parameters (body height and weight) and training experience, and thus with the intensity and volume of training. This indicates a correct training process that does not interfere with the proper development of the body in terms of tissue and biochemical composition.

Introduction: We performed a computed tomography analysis of muscle composition characteristics in hip fracture patients and non-hip fracture controls. Methods: In total, 43 patients (9 men, 34 women) were included in the hip fracture group, matched 1 to 1 with non-hip fracture controls. Muscle cross-sectional areas were measured in axial CT scan at the body level of the 4th lumbar vertebra (L4), intervertebral disc level between the 5th lumbar vertebra and the 1st sacral vertebra (L5-S1) and just below level of the lesser trochanter (LT). Attenuation was also evaluated through the mean Hounsfield unit (HU) in these areas. Results: The cross-sectional area per weight (CSA/Wt, mm2/kg) of psoas muscle and extensor muscles of the spine showed a significant difference between the 2 groups at both L4 (9.7 vs. 12.4, p < 0.001 and 26.3 vs. 29.2, p = 0.025) and L5-S1 (9.6 vs. 11.5, p = 0.001 and 8.8 vs. 10.3, p = 0.041) levels. In addition, the HU of these muscles differed significantly between the 2 groups at both L4 (33.3 vs. 47.6, p < 0.001 and 13.7 vs. 30.2, p < 0.001) and L5-S1 (39.7 vs. 52.6, p < 0.001 and 3.8 vs. 15.1, p = 0.012) levels. There was no difference in abdominal wall, gluteal, or thigh compartment musculature between the groups. Conclusions: Poorer quantity and quality of psoas muscle and extensor muscles of the spine rather than whole body muscles may contribute to falls and were characteristic features of the hip fracture patients in this series. These findings should be considered when recommending a preventive exercise and rehabilitation protocol.

Purpose: Despite many researches that have been done in the field of biorhythm and due to lack of single view among scholars, as well as importance of forecasting of athletes’ performance to improve their results, the purpose of this study is to determine relationship between biorhythm (physical cycle) and sports performance of Iranian Super League women basketball players. Material: This is a descriptive-correlational study. Statistical population was women basketball players in 1394-95 women's Super League and the statistical sample included all of the players of the teams, qualified as semi-finalists (44 players). The tool, used in this research, was athletes’ performance questionnaire (Charbonneau, 2001) containing five questions by a Likert scale from 1 (poor) to 5 (excellent) points. Biorhythm software and descriptive tests and also inferential statistical test including Chi-Square, independent T-test and one way ANOVA at significance level of in SPSS software were used for analyzing the collected data. Results: results showed that there was no significant relationship between physical energy and performance of athletes (p = 0.85). Also the results of one way ANOVA test showed that there was no significant difference between performance of athletes at three levels (positive, negative and critical) and physical cycle (p = 0.96). The value of Chi-Square was equal to 2.63 that showed there was no significant relationship between different levels of physical cycle and the results (win or lose) of match (p = 0.026). Conclusion: The results of this study revealed that physical performance did not depend on 23-day cycle, stated in the Biorhythm theory, and there was no evidence proving existence of these cycles. It can be concluded that there is no justifying reason to use the Biorhythm software in hard exercises.

Abstract: Physical exercise stimulates sweat from inside the body to transfer the heat out of it. Sweat consists of both water and electrolytes, including chloride ion, so if the excretion of water and electrolytes is not corrected can disturb the body’s homeostasis and health. This study aimed to determine the differencesof serum chloride levels before and after light intensity physical exercise. This study was a pre - experimental with one group pretest – posttest design. There were 30 respondents obtained by using purposive sampling method. The respondents did a brisk walk on a treadmill at 50-63 % heart rate maximum intensity for 30 minutes. Blood was taken before and after the exercise in order to examine the levels of serum chloride. The results of this study were processed by using Wilcoxon test. Averagely, the level of serum chloride before exercise was 106,23 ± 2,208 mmol/L, and 106,90 ± 1,9 mmol/L after exercise. Statistical test result showed p = 0,007. It is concluded that there is a significant difference on the levels of serum chloride before and after light intensity exercise in the students of Medical Faculty Sam Ratulangi University.

The Difference

The public is increasingly aware of the importance of exercise for the elderly because exercise is an option to reduce complaints due to setbacks and improve the health of the elderly. In fact the implementation in the field is often wrong as in Banjar Benaya which implements routine exercises only once a week with a duration less than 30 minutes, does not pay attention to nutritional needs, does not use sports clothing, and displays that are not clear. The measurement of elderly physical fitness is still relatively low. Based on these problems, improvements were made to the application of ergonomic elderly gymnastics due to improve elderly’s physical fitness and increase the bone mass. This study used a treatment by subject design conducted in April 2017-August 2018. The target population was all elderly in Denpasar and the affordable population was determined by multistage random sampling then selected Banjaya Benaya Peguyangan Village with a sample of 20 people who met the inclusion criteria. The data collection were physical fitness and bone mass. The difference in treatment effects were analyzed using a Paired Sample t-Test with α = 0.05 for data with normal distribution and Wilcoxon test, α = 0.05 for data with abnormal distribution. Data showed that there were differences in physical fitness improvement in Period I and Period II after 8 weeks of gymnastics at 43.43% with very bad categories being bad, the difference in increase in whole body bone mass was 16.76% and leg bone mass 68.67%. Analysis of Paired Sample-t-Test physical fitness data and Wilcoxon test for bone mass data in Period I and Period II after gymnastics for 8 weeks, found that there was a significant difference (p <0.05). It can be concluded that ergonomic elderly gym can significantly improve physical fitness and increase bone mass of the elderly. It is recommended that the elderly continue to exercise with a duration of 30-45 minutes, the frequency of 3 times a week to maintain elderly’s physical fitness.

Volleyball Players

Objective: To achieve the excellent levels of athletic performance, professional athletes need to do continuous exercises and strengthen special muscles of the body and have to spend a lot of time training in that sport. As a result, depending on the prevailing condition of each sport, the physical orientation and the degree of abnormalities of the athletes in that sport are affected. Methods: The current study is descriptive and cross-sectional. The statistical population was 12-14 years old boys in middle and high school. The statistical sample of this study included 30 people (13 volleyball players and 17 basketball players) with a targeted training rate of at least three sessions per week. The Chippaux Smirak Index (CSI) method was used to evaluate the arch of the foot and to determine the angles and degrees of kyphosis and lordosis in radiographs. Independent t-test and Mann-Whitney test were used to compare the variables of motor skills and posture by SPSS V. 18 at a significant level of 0.05. Results: The results of independent t-test to compare the variables of motor skills in the two groups of volleyball and basketball show that there is a significant difference between the two groups in the Sargent test and 4mX9m (P=0.000) (P≥0.05). The results were different in strength test (P=0.41) and Sit-up (P=0.75) so that there was no significant difference between the two groups (P≥0.05). The results of Mann-Whitney test to compare posture-related variables showed that there was no significant difference between the two groups in any of the parameters of varus, valgus, pronation, supination, lordosis, kyphosis, foot flat (P≥0.05). Conclusion: The results showed that volleyball players have more impressive and explosive power than basketball players, but in terms of muscle strength and endurance, there is not much difference between these two groups, which is probably due to the nature and specific characteristics of their sports. Therefore, it seems necessary to pay more attention to athletes’ training programs to improve their motor skills and physical condition. In this study, the behavior and common habits of the subjects in interaction with the environment and hereditary characteristics have not been studied, so more research is needed in the etiology of musculoskeletal abnormalities.

ABSTRACT Purpose: to investigate forward masking by comparing latencies values of positive and negative peaks in frequency-following responses (FFR) recordings, in normally hearing young adults. Methods: from a database, 20 FFR recordings were selected, 10 being from men, and 10 from women, aged 18 to 25 years, with normal hearing. They were qualitatively analyzed by two experienced researchers and also analyzed, according to two different protocols of recording identification: (i) predominance of positive peaks - PV, A, PW, PX, PY, PZ, and O waves; and (ii) predominance of negative peaks - V, A, C, D, E, F, and O waves. The Shapiro-Wilk normality test, the Wilcoxon test, and the Student’s t-test were conducted, by adopting the significance level of p<0.05. Results: the comparative analysis of latency peak values did not reveal any significant difference between the studied protocols. However, the standard deviation was higher for absolute latency values as compared to negative peaks, suggesting an inverted pattern of what was expected. Conclusion: forward masking was identified in both proposals and the protocol of predominant positive peaks was less variable.
