Abstract BackgroundThe lifestyle of children has a significant impact on the future health of the whole society. Therefore, health education, prevention and monitoring of health determinants is important at every stage of ontogenesis. This requires a thorough knowledge of the schoolchild's environment, perceived as a wide set of stressors, including not only genetic but also epigenetic factors. One of them is the issue of the correct and abnormal body posture at school and on the way there.MethodBody posture tests were carried out in a group of 65 students aged 7 years, using the projection moiré method in 4 positions: 1-habitual posture, 2-posture after 10-minute of asymmetric axial load, 3-a posture after one minute of the load removal, 4- a posture after two minutes of the load removal. Physical fitness was measured with the Sekita test. ResultsThe significance of differences between the 1st and 2nd measurements was analyzed to determine the impact of the backpack load and the correlation with physical fitness, and to study its influence on the value of the differences in posture features. ConclusionsCarrying school supplies on the back induces significant changes in the value of the features describing the body posture in the frontal plane. It should be assumed that the greater the weight of the container and, carrying time and intensity of physical effort is the greater the changes will be. Relatedly, it is not recommended to carry school supplies weighing more than 4 kg by first-grade students.Physical fitness has a various and sex-dependent influence on the value of changes in body posture features because of carrying school supplies. Among boys it significantly affects the asymmetry of the torso bend, shoulder height, the waist triangles height and width, whereas among girls it affects the asymmetry of the shoulders and the distance of the angles of the lower shoulder blades from the line of the spinous processes of the spine. Among boys the changes in the value of posture features are mostly influenced by endurance and speed, but strength, power and agility are of lower influence, whereas among girls only agility matters.

Introduction: Postural abnormalities are common in every age group. They often involve discomfort or pain. Unfortunately, specialist posture correcting body postures are almost exclusively for pre-school and school children. There is a widespread belief in the beneficial effects of swimming on the body posture. Some even think that swimming can replace corrective exercises. The aim of the study was to evaluate the changes in the quality of body posture and body balance under the influence of 60-minute intensive swimming training in people aged 20-22 years, whose level of swimming skills was determined as average. Material and methods: The study was conducted on a group of 9 people, students of the State Higher Vocational School in Tarnów. Ultrasonic device Zebris Pointer was used for three-dimensional assessment of body posture. The position of the shoulder and iliac girdle, the shape of the spine, the inclination of the sacrum bone and the inclination of the body in the sagittal and frontal plane were analyzed. The test was repeated before and after the one-hour lecture and before and after one-hour, intensive classes at the swimming pool. The results were developed in the Statistika v10 program. Descriptive statistics, non-parametric Friedman test and Kruskal posthoc test were used. The significance level α = 0.05 was assumed. Results: There was a statistically significant increase in pelvic rotation under the influence of swimming training. There was also a slight deterioration of the spine position in the frontal plane. Exercises improving swimming in the classic style did not affect the depth of thoracic kyphosis and lumbar lordosis. After 60 minutes spent in a relaxed sitting position, deepening thoracic kyphosis was observed. However, this change was not statistically significant. Conclusions: It is not recommended to treat swimming as a substitute for corrective gymnastics. Intensive swimming training can exacerbate existing body posture errors in people who are just improving their swimming technique.

Purpose: A correct body posture plays an important role in people’s health, especially for children and adolescents who are in intensive development. Exercise regularly can increase their health, but there is also an adverse influence on children and adolescents. Thus this review evaluates the impacts of basketball, volleyball, football, gymnast training on the body posture of adolescents. Methods: The literature collect was complete through databases which included Google Scholar, PubMed, and ScienceDirect. Eight of 480 studies met the inclusion criteria. The collecting articles have assessed the impact of the sport of basketball, volleyball, football, and gymnast on body posture. Result and Conclusion: According to the analysis, the sport of basketball and volleyball play a negative effect on adolescent’s body posture and deviation of body posture increase as training time longer. Further research is required to be done to investigate football training to affect body posture because no studies are confirming the effect of football on body posture. However, gymnast training showed a symmetrical body posture, but the changes of the spine in the sagittal plane in adolescents are worthy of attention. Therefore, it is important to notice that the training program not only aims at the outcome but also promote the harmonious development of the adolescent.

Healthy physical fitness is one of the hot topics discussed by scholars at home and abroad in recent years, and it is a key indicator for evaluating students’ physical function and body shape. Aerobics, also known as bodybuilding, means that the body and health of students should have a better promotion effect, but in reality, many students found that after elective aerobics, body shape and health level basically did not improve, which is related to the setting of aerobics courses, especially the lack of physical training. Aerobics and other sports have common requirements in physical training, such as strength quality, speed quality, endurance quality, agility quality, and flexibility quality. This article is aimed at studying the impact of healthy physical fitness based on big data mining technology on the teaching of aerobics. On the basis of analyzing the process of data mining, the composition of healthy physical fitness, and the role of aerobics, it is used to test students in a certain university through experimental methods and statistical methods. Carry out aerobics teaching experiment, and compare and analyze the data measured by the experimental samples. The experimental results show that the use of healthy physical fitness in aerobics teaching can effectively promote the learning and improvement of aerobics skills.

Mammary gland cancer, commonly known as breast cancer, is the most common malignancy in women in Poland. The occurrence of the disease and its treatment are associated with a decrease in physical fitness and endurance of the body, and also make it difficult to meet basic life needs and result in a deterioration in the quality of life. The aim of the study is to present physical activity in women with breast cancer and after mastectomy. Analysis of professional literature and available research results in patients undergoing oncological therapy in the treatment of breast cancer indicates the need for them to undertake physical activity and physiotherapy in order to minimize the effects of chemotherapy, radiotherapy, and mastectomy. Analysis of studies in terms of the impact of physical activity on the rehabilitation and recovery of patients with breast cancer showed a significant impact of physical fitness on bone mineral density as the most important factor in the development and maintenance of normal bone metabolism. Physical exercises have also been shown to have a positive effect on patients during and after treatment. Regular physical exercise in women treated for cancer is essential and has a significant impact on reducing muscle deficits and the entire skeletal system.

Abstract Objective It has been suggested that overweight/obesity (OW/OB) impairs the normal development of body posture in children and adolescents; however, to date, no study has systematically reviewed or quantified the effect of OW/OB on the development of postural alterations in children and adolescents. The purpose of this study was to systematically review the association between OW/OB and postural alterations in children and adolescents and to quantify the evidence on whether children and adolescents with OW/OB have a higher risk of developing postural alterations than their peers of normal weight. Methods PubMed and Web of Science databases were systematically searched from inception to March 9, 2020. Studies investigating the association between OW/OB and postural alterations in children and adolescents were selected. Nonoriginal articles, participants with movement pattern diseases, and adolescents studied while pregnant were excluded. Two independent reviewers conducted the study selection and data extraction. Qualitative synthesis of evidence and random effect meta-analyses (risk ratio [RR]) were performed. Results Seventy-three studies (5 longitudinal and 68 cross-sectional) met the inclusion criteria involving 1,757,107 children and adolescents. There was consistent evidence supporting associations of OW/OB with rounded shoulder, lumbar hyperlordosis, genu valgum, and flatfoot. Our meta-analysis showed that children and adolescents with OW/OB had a significantly higher risk of lumbar hyperlordosis (RR = 1.41), genu valgum (RR = 5.92), flatfoot (RR = 1.49), and an overall altered posture (RR = 1.68) when compared with their peers of normal weight. The presence of genu valgum and flatfoot were the most robust results. Conclusions Based on these findings, OW/OB is associated with the presence of postural alterations in children and adolescents. Impact This is the first study that has systematically reviewed the effect of OW/OB on the development of postural alterations in children and adolescents.

Introduction and aim of the study: The body posture, which is one of the determinants of health and functional efficiency, changes depending on gender, age and psychophysical condition. Defining a pattern of correct posture is extremely difficult as it is a highly individualised feature. The aim of this paper was to compare the body posture of women in three periods of ontogenesis: girls in puberty, young adult women and women in the geriatric age. Material and methods: 150 women were examined: 50 12-year-old pupils, 50 20-22-year-old students and 50 women aged 60-84. Their height and weight were measured, BMI calculated and the status of body weight determined as normal, overweight or obese. The Zebris Pointer ultrasound system analyzed the position of the spine in the sagittal and frontal plane, the symmetry of the shoulders and pelvis in the frontal plane, and the balance of the torso in the sagittal and frontal plane. The results were developed with the Statistica programme. Basic descriptive statistics, multiplicity tables, Shapiro-Wilk test (study of normality of distribution) and Kruskal-Wallis test (inter-group comparison) were used. Differences between groups were assumed to be significant when p<0.05. Results: Age significantly differentiated the BMI index of the surveyed. Overweight and obesity was more prevalent in the oldest age group. The size of thoracic kyphosis expressed in degrees was similar in all the surveyed, although hypokyphosis was observed more frequently in the female pupils and hyperkyphosis in the female students. Lumbar lordosis was significantly higher in the students when compared to the other groups. Hypolordosis was most common in the seniors. The students and seniors also differed in terms of the balance of the torso in the sagittal plane. Excessive backward inclination was diagnosed in 42% of the students (total backward shift of the centre of gravity of the human body), which was twice as rare in the female students and four times as rare in the seniors. Asymmetric position of the right and left shoulder and hip girdles was common in every group of the women surveyed. Side bendings of the spine were most often observed in the female pupils, and least frequently in the seniors. Left-sided bendings were more frequent than right-sided ones. Conclusions: The age of women affects the position of the torso more in the sagittal plane than in the frontal one. The size of lumbar lordosis is an element of the body posture most significantly differentiating women between 12 and 84 years of age. Hyperlordosis is more characteristic of young adult women, whereas hypolordosis of seniors. Hyperkyphosis is most common in female students while hypokyphosis in adolescent girls.

Emg Patterns

A deviation from the dorsal-side-up body posture in quadrupeds activates the mechanisms for postural corrections. Operation of these mechanisms was studied in the rabbit maintaining balance on a platform periodically tilted in the frontal plane. First, we characterized the kinematics and electromyographic (EMG) patterns of postural responses to tilts. It was found that a reaction to tilt includes an extension of the limbs on the side moving down and flexion on the opposite side. These limb movements are primarily due to a modulation of the activity of extensor muscles. Second, it was found that rabbits can effectively maintain the dorsal-side-up body posture when complex postural stimuli are applied, i.e., asynchronous tilts of the platforms supporting the anterior and posterior parts of the body. These data suggest that the nervous mechanisms controlling positions of these parts of the body can operate independently of each other. Third, we found that normally the somatosensory input plays a predominant role for the generation of postural responses. However, when the postural response appears insufficient to maintain balance, the vestibular input contributes considerably to activation of postural mechanisms. We also found that an asymmetry in the tonic vestibular input, caused by galvanic stimulation of the labyrinths, can affect the stabilized body orientation while the magnitude of postural responses to tilts remains unchanged. Fourth, we found that the mechanisms for postural corrections respond only to tilts that exceed a certain (threshold) value.

It is recommended that proper incorporation of healthy habits of physical activity in childhood and adolescence has a positive impact on a physically active lifestyle in adult life. Thus, the present study aimed to verify the effects of four weeks of systematized physical activity in addition to the classes of Physical Education on parameters of physical fitness related to health of children and adolescents. The sample was selected by convenience and composed of 73 children and adolescents aged 8-11 years. The subjects were subdivided into 2 groups; one group of children exclusively attending Physical Education classes (PEC); and another group that performed Systematized Physical Activity (SPA). The following tests were applied; the abdominal test to assess strength and muscle resistance; the Paccer to verify cardiorespiratory fitness; and the adapted sit-and-reach to evaluate flexibility. In addition, the Body Mass Index (BMI) and relative fat (%F) were assessed. Sample characterization data and motor tests are presented as median and interquartile range. The ANOVA test of repeated measurements was used to verify the effect of the moments. The results pre training did not demonstrate differences between groups in measures of body mass, stature, BMI, or motor tests. The effects of physical training were observed in all motor tests in favor of the SPA, while the PEC did not demonstrate significant differences between moments. In conclusion, four weeks of additional systematized physical activity promoted a significant positive effect in motor tests applied with a focus on heath.

ABSTRACT Introduction: Sports dance is widely known as a competitive game, but as a leisure activity, there is little research on the efficacy of human health and fitness. Sports dance, as a popular national fitness exercise, has sound health promotion effects. At present, domestic and foreign researches mostly focus on the impact of sports dance on young men and women. Objective: This study will explore the influence of regular physical dance exercises on the body shape, function, and quality of middle-aged and older adults, provide a scientific basis for the role of physical dance in national fitness. Methods: This study recruited 20 healthy middle-aged and elderly members of a leisure sports dance club without professional dance experience for three months of dance training. The first two weeks are pre-experiments five times a week. Each exercise time is 60 minutes. The last ten weeks are formal experiments, two times a week, 90 minutes each time, and no other physical exercises are involved in everyday life. By comparing part of the body shape, physical function, and physical fitness index before and after the experiment, the impact of sports dance on middle-aged and older adults’ healthy physical fitness is evaluated. Results: After three months of physical dance exercise with different dance styles, in male, BMI index, body fat percentage, waist circumference, hip circumference, and thigh circumference indicators all decreased, but there was no significant difference. In women, BMI index, body fat percentage (P<0.01), waist circumference (P<0.05), diastolic blood pressure (P<0.01), sitting body forward bending (P<0.05), and standing with one foot and closed eyes all increased. In women, the indexes of grip strength (P<0.01), forward bending in sitting position (P<0.055), and standing with eyes closed on one foot all increased. Conclusions: It is suggested that long-term moderate-intensity aerobic sport dance exercise can improve the body shape of middle-aged and older adults and help increase physical fitness; meanwhile, sports dance can effectively improve the cardiovascular function of middle-aged and elderly subjects. Level of evidence II; Therapeutic studies - investigation of treatment results.
