The aim of this research is to compare the motoric features of badminton players of the national teams participated in International tournament under-15, and to determine whether there is a correlation between the development level of motoric features and the results. Totally 48 players participated in the study, from 6 countries (Turkey, Azerbaijan, Bulgaria, Macedonia, Serbia, Georgia) participating in the 5th International Rumi Child Sport Games, 24 of whom were females and 24 males. Stature, bodyweight, body mass index (BMI), flexibility, dominant and non-dominant hand grasping power, standing long jump, sit-up for 30 seconds, vertical jumping test, and anaerobic strength values of the participants were detected. It was determined that there were statistically significant differences (p<0.05) between the countries in terms of dominant hand grasping power, vertical jumping, and standing long jump values of the male players; and in terms of bodyweight, BMI, dominant and non-dominant hand grasping power values of the female players. As conclusion, it was found that the motoric features of the players ranked in the International Tournament under-15 were in better level, and it can be concluded for badminton sport that development of motoric features played an important role for success alongside with technique and tactic features.

Background. The main purpose of this study was to explore the body-mass index and waist circumference associated with physical fitness by gender. Methods. In this cross-sectional study, we included 1036 adolescents (55.4% girls) from eight randomly selected secondary schools within the city of Zagreb (Croatia). Body-mass index and waist circumference were objectively measured. Physical fitness included three tests: (1) 1 min sit-ups, (2) standing long jump and (3) a sit-and-reach test. Associations were calculated using linear regression models. Results. Boys had higher body-mass index and waist circumference values, compared to girls (p < 0.001). They also performed better in 1 min sit-ups and the standing long jump tests (p < 0.001), while girls obtained higher values in the sit-and-reach test (p < 0.001). In boys, body-mass index and waist circumference were associated with 1 min sit-ups and the standing long jump. In girls, waist circumference was also associated with 1 min sit-ups and the standing long jump, while body-mass index was only associated with this standing long jump. Conclusions. Our study shows that anthropometric indices have non-linear associations with physical fitness tests in a large sample of Croatian adolescents. Screening for thinness and obesity to predict the level of physical fitness should be of a great interest.

Abstract BackgroundAlthough evidence suggests that cardiorespiratory fitness is the most important component associated with future health, little is known of how it is associated with multiple other physical fitness components. Since various physical fitness aspects do not change the same as cardiorespiratory fitness during childhood, it is necessary to establish possible associations between cardiorespiratory fitness and other physical fitness components in children. Therefore, the main purpose of the study was to test the associations between cardiorespiratory fitness with motor performance and body size in 7-14-year-old children.MethodsIn this cross-sectional study, we recruited 1612 children (52.5% girls). Health-related physical fitness components included: 1) body-mass index (kg/m2) calculated from height and weight (measure of body size), 2) sit-and-reach test (measure of flexibility), 3) standing long jump (measure of explosive strength), 4) sit-ups in 30 sec (measure of repetitive strength), 5) 10x5 shuttle run test (measure of agility) and 6) 20-m shuttle run test (measure of aerobic capacity). The associations were performed using generalized estimating equations with β coefficients.ResultsAfter adjusting for age, cardiorespiratory fitness was associated with sit-and-reach test (β=0.13, p<0.001), standing long jump (β=0.59, p<0.001), sit-ups in 30 sec (β=0.53, p<0.001) and 10x5 shuttle run test (β=-0.56, p<0.001) in boys. In girls, cardiorespiratory fitness was associated with body-mass index (β=-0.12, p<0.001), sit-and-reach test (β=0.21, p<0.001), standing long jump (β=0.25, p<0.001), sit-ups in 30 sec (β=0.36, p<0.001) and 10x5 shuttle run test (β=-0.40, p<0.001). No significant associations between cardiorespiratory fitness and body-mass index in boys were observed.ConclusionsAlthough significant, cardiorespiratory fitness is weakly to moderately associated with other physical fitness components, pointing out that such measure should be tested separately from other aspects of physical fitness in school-aged children.

The aim of this study is to contribute expansion of knowledge about the level of the performance and health oriented fitness at represented students of Physiotherapy on Faculty of Health Studies Jan Evangelista Purkyně University in Ústí nad Labem. We compare resulting values with the values that were obtained by general population and students of Physical education and sports. Students participated these tests: progressive run for 20 meters, 2 kg heavy ball throw with both hands, standing long jump with both legs together, flexed – arm hang forward grip for woman, sit-up test 1 minute, deep bend in sitting position, Iowa Brace and calculated Body mass index (BMI). We asked two questions for our study. First, what is the level of motor skills students of Physiotherapy so academic students, what is the difference of level of motor skills between students of Physiotherapy compared with general population and second, what is the difference of the level of motor skills between students of Physiotherapy and students of Physical education and sports. Results showed that students of Physiotherapy had the same level of motor skills such as general population. Students of Physiotherapy had the same level in only two tests – deep bend in sitting position – flexibility and flexed-arm hang forward grip for woman with students of Physical education and sports.

The main purpose of this study was to determine the impact of somatotypic profile and body mass index on the physical conditions of 12-14 year-old students, based on the results of tests for assessment to motor skills included in assessment system at the Physical education and sports in schools. The 64 young men and 70 girls we will explore are from two different schools in Blagoevgrad, which subsequently were divided into four groups: two groups for the boys and two for the girls. The study groups have antropometrichal parameters: height - 161.5 ± 8.2 cm, weight - 55.25 ± 18.26, and BMI of 21.01 ± 5.82 (M ± SD) for the boys and height 159.7 ± 7.22 cm, weight 52.02 ± 10.66 and BMI (kg / m2) 20.36 ± 3.85 (M ± SD) for the girls. The participants of this study completed 4 tests to determine the level of physical fitness, which are included in the System for Control and Assessment of the Achievements of the Students in Physical Education and Sports, used in the second stage of the primary education in Bulgaria until 2019 year. The functional tests were: for boys they are: 50m (sec) sprint running; 600 m (sec) for endurance; throwing a medicine ball 3 kg (cm) and standing long jump with both feet. For the girls: 50m (sec) sprint; 300m (sec) for endurance; sit ups (pc) and standing long jump with both feet (cm). The Score are from 1 to 5, depending on the value of the result. The somatotype was measured using the Heath-Carter method. The results show mean values for endomorph of 4.44 ± 1.47, for mesomorph of 4.94 ± 2.4, and for ectomorph of 3.12 ± 1.57 for the girls (mesomorph-endomorph) and values (M ± SD) of 3, 50 ± 1.58 for endomorphism, 5.74 ± 3.04 for mesomorphy and 3.28 ± 1.77 ectomorphy for the boys (balanced-mesomorph). We used GraphPad Prism version 3.0, for statistical analysis. The correlations between somatotype index, body mass index, and results of functional tests were calculated by coefficient of Pearson (p<0,05). We checked all possible relationships between ectomorphic, mesomorphic, and ectomorphic index with condition test results. Only 6 of them having significant correlation: between mesomorph and result of 50 m at Male7 r = 0.331, p = 0.048; between the ectomorph and the result of 50 m at Female7 r = -0.346, p = 0.045; between endomorph and 50 m result at Female7 r = 0.459, p = 0.006; between the endomorph and the result of a jump from the site at F7 r = -0.414, p = 0.0015; between mesomorphs and the result of a standing long jump of Female7 r = -0.519, p = 0.0016; between ectomorphs and a score of 50 m at Female1 r = -0.3359, p = 0.043 (Pearson). The most significant correlation was found between the BMI index and the 50 m result at Male7 r = 0.832, p <0.0001 (Pearson). We identified 11 of a total of 64 possible combinations; five of which between functional capability, BMI and six with somatotype index; five were low correlations (0.3–0.5) in the range r = 0.300– 0.340; only three high positive correlations were found in the range r = 0.693 - 0.832, p <0.0001 (Pearson); seven correlation dependencies were established with the result of the test for 50 m (sec); three with a jump test (cm) and one with 600 m (sec). In conclusion we can say that our hypothesis is not confirmed, because despite the normal weight, BMI and good somatotypic profile of the subjects , they have no statistically significant effect on the functional capabilities of students.

Much of the evidence examining temporal trends in fitness among youth has found a decrease in measures of muscular strength and muscular power over recent decades. The aim of this study was to examine trends in lower body muscular power in Spanish boys over 47 years. In 1969 140 boys (10–11 years; body mass index = 19.24, SD = 2.91 kg/m2) and in 2016, 113 boys (10–11 years; body mass index = 19.20, SD = 3.15 kg/m2) were recruited. Lower body power was assessed using the vertical jump (VJ) and standing long jump (SLJ) tests. Significant differences and a large effect size were shown between groups in the SLJ (p = 0.001; d = 0.94) and the VJ (p = 0.001; d = 0.66). SLJ data in 1969 were higher (1.52 m, SD = 0.19) when compared to the 2016 data (1.34 m, SD = 0.18). The VJ performance of the 1969 sample was also higher (25.95 cm; SD = 6.58) than the 2016 sample (21.56 cm; SD = 4.72). SLJ and VJ performance of the 2016 group decreased 11.8% and 16.9%, respectively. There were no significant differences between groups in body mass index. The results indicate a secular decline in lower body muscular power in 10–11-year-old Spanish boys with no significant changes in body mass index over the 47-year study period.

Studies on the role of physical fitness, physical activity and obesity as risk factors for temporomandibular disorders (TMD) are scarce. The aim of the present study was to evaluate the association of TMD symptoms with physical fitness, physical activity and body mass index (BMI) among Finnish conscripts. The study sample consisted of 8685 Finnish conscripts. Data on self-reported TMD symptoms were used as outcome variables. Physical activity (questionnaire), physical fitness (measured with physical tests: Cooper test, push-ups, sit-ups and standing long jump) and body mass index (BMI) were used as explanatory variables. The associations between TMD symptoms and explanatory variables were evaluated using Chi-squared test and logistic regression analysis. The prevalence of all TMD symptoms was significantly higher among those who exercised more rarely than weekly. Pain-related TMD symptoms were also significantly more frequent among those who were overweight (BMI ≥ 25). Poor push-up results and overweight (BMI ≥ 25) were significantly associated with jaw pain and TMJ pain at jaw rest. The present study showed that good physical fitness may be a protective factor against TMD pain. Dentists should also be prepared to motivate TMD patients to physical activity and regular exercise as part of the treatment.

Introduction Hand grip strength is used in evaluation of muscle strength and is also increasingly being used as an indicator for nutritional status. The maximum force applied voluntarily by the subject is called maximum handgrip strength, which is measured in kilograms. Muscular endurance is the ability of a muscle or muscle group to perform against a load for an extended period of time, measured in seconds. This study aims to correlate body mass index with handgrip strength and handgrip endurance in medical students. MethodsThis is a cross sectional, observational study which included 74 undergraduate students of Maharajgunj Medical Campus by convenient sampling method. Body mass index was calculated by Quetelet’s formula. Camry digital hand dynamometer was used to measure handgrip strength in the dominant hand in kilograms. Participants were instructed to hold dynamometer with maintained pressure of 30% of maximum handgrip strength for as long as possible to determine the handgrip endurance. Statistical analyses were performed with SPSS Statistics software. ResultsThe handgrip strength was more in males than females with a mean of 43.09±3.72 kg, while handgrip endurance was more in females with a mean of 123.60±50.65 sec. Positive correlation was seen between body mass index and handgrip strength (r=0.23 and p=0.045). Body mass index and handgrip endurance also showed positive correlation (r=0.34 and p=0.003). ConclusionSignificant correlation of body mass index with handgrip strength and handgrip endurance was seen in medical students.

Abstract Background Dynapenia is defined as an age-related loss of muscle strength. There is little information on dynapenia in cancer patients and on how it relates to anthropometric variables. The aim of this study was to analyze the presence of dynapenia and its association with anthropometric variables in hospitalized cancer patients. Methods Participants comprised adult and elderly cancer patients evaluated within the first 48 h of hospital admission to a tertiary public hospital, a referral center for gastrointestinal tract surgery. Anthropometric variables were measured according to standardized protocols. Dynapenia was identified based on handgrip strength (HGS), according to the cutoff points defined by the European Working Group on Sarcopenia in Older People (EWGSOP2), with values for women < 16 kg and for men < 27 kg. Statistical analysis was performed using SPSS software, version 22.0, with a significance level of 5%. Results This study included 158 patients aged in average 59.5 ± 14.0 years; of these, 53.6% were elderly, 58.9% non-white and 59.5% had some degree of malnutrition. The most prevalent type of cancer was that of the lower gastrointestinal tract (33.5%). The presence of dynapenia was observed in 23.4% of the patients and cachexia in 36.1%. There was an association between dynapenia with age (p < 0.001), life stage (p = 0.002) and race/color (p = 0.027), and also with body mass index (BMI) (p = 0.001) and adductor pollicis muscle thickness (APMT) of both hands (p < 0.05). After logistic regression analysis, adjusted for the sociodemographic variables, the APMT of the dominant hand and the low weight determined by body mass index remained associated with the occurrence of dynapenia (p < 0.05). Conclusions In this study we confirmed that dynapenia was present in cancer patients, being associated with APMT of the dominant hand and low weight. HSG was proven to be a reliable and complementary measure to be added to the process of assessing nutritional status, contributing to the nutritional diagnosis of these patients and to the detection of early muscle depletion.

Introduction: An individual’s overall muscle strength is commonly assessed by a power grip measurement, a reliable indicator of functional capacity and physical condition. The development of muscle parallels the changes of body composition during growth. Aim of this study is to examine the correlationship between hand grip strength and anthropometric. Methods: This cross-sectional study involved 76 male students of Dhammasavana School, aged between 12 – 16 years old, North Jakarta. Hand grip strength was examined using a digital dynamometer on the dominant side. Statistical analysis was computed using SPSS ver. 15.0 program with Spearman correlations test. Significance was set at p<0.05. Results: Dominant hand grip strength was found to have significant (p<0.05 - 0.001) positive correlation with height (r=0.612), lower arm muscle-and-bone cross-sectional circumference and area (CSA) (r=0.553 and r=0.553 respectively), hand length (r=0.548), forearm length (r=0.540), age (r=0.520), weight (r=0.416), and forearm girth (r=0.376). Conclusion: No significant correlation between grip strength and body mass index was found. Positive correlations between the variables mentioned above conclude that the higher the value of the anthropometric measurements, the greater the strength generated in a power grip.
