Background: Taekwondo (TKD) is a combat sport practiced by millions of children, young people and adults around the world.1 It is an Olympic sports branch with many complex features and constant interaction between two opponents in the competitions, where attack-contact techniques are applied quickly, attacking techniques are strong2,3 but also have good flexibility. Aim: This study has been carried out to identify the relationship between body composition of taekwondo practitioners aged 14-16 who regularly practice taekwondo, and their aerobic endurance. Methods: A total of 33 registered taekwondo practitioners (17 male, 16 female) participated to this study on a voluntary basis. The age, height, weight, and body mass index of all the athletes who took part in the study are 14.96±0.80 years, 162.59±11.59 cm, 50.97±7.51 kg and 19.14±2.39 kg/m² respectively. The group who participated to the study practice taekwondo two days a week, for 2 hours each, for a period of 1.5 years. The aerobic endurance of taekwondo athletes was measured by 20-meter-long Shuttle Run Test. In order to measure the body composition values of the athletes, measurements of skinfold thickness (biceps, triceps, subscapula, subrailiac) were carried out. In calculating the body density, the formula of Durning-Womersley was used; and in calculating the body fat percentage, the formula of Siri was employed. Data was evaluated by SPSS 22.0. The normality distribution of the data obtained at the end of the study was evaluated by Kolmogorov-Smirnov test and it was observed that the data was in line with normal distribution. Following the normalcy assessment, the relationship between body compositions and aerobic endurances was determined by Pearson Correlation analysis. Results: It is possible to say that the body composition values of taekwondo practitioners aged 14-16 have positive and negative impact on their aerobic endurance. It is observed that as the values 20-meter Shuttle Run test increases, fat percentage of athletes decreases. Conclusion: It is concluded that the findings obtained from the research results support the literature, and that body composition and aerobic capacity are important as performance criteria in many studies. It is thought that it may be beneficial for the athletes to perform aerobic endurance exercises during the annual training periods to perform the necessary practices to optimize their body composition and improve their aerobic capacity.

The Relationship

The aim of this study is to analyze the relationship between body composition and physical fitness parameters in children. 286 male and 311 female students have voluntarily participated in the study. Data on body composition have been obtained through the measurements of the students’ height, body weight, BMI, body fat percentage, length (sitting height, arm length, forearm length, leg length, thigh lengths), circumference (elbow, shoulder, biceps (flexion) , buttock, knee, waist, calf, ankle). For somatotype characteristics, the Heat-Carter somatotype grading method has been used. The Sit-Reach Flexibility Test (cm) has been used to determine the characteristic of flexibility; the 20 m. Speed Test (seconds) to determine speed; the 20 m. Sit-up test to determine endurance; Takkei hand dynamometer to determine right-left hand grip strength; Takkei back and lift dynamometer for leg strength and the Flamingo Balance Test for balance have been used. In the analysis of data, the SPSS 16 software has been used and T test and Pearson correlation test have been carried out (p<0.05). Between the body composition and physical fitness parameters of female and male students, a statistically significant relationship has been found with the exception of age, arm and waist measurements (p<0.05). In both genders, positive or negative relationships have been found between height, circumference measurements and somatotype characteristics and performance tests (p<0.05). It was found that there is a negative or positive relationship between the heights, circumference measurements and somatotype characteristics and their strength, endurance, speed, flexibility and balance characteristics of female and male children aged 10-12. As a result, it has been seen that the body composition of children aged 10-12 affects the physical fitness parameters. Children in this age group which is both a period of growth and development and skills selection period for numerous sports branches should regularly be followed by their physical education teachers, anthropometric measurements and performance tests should be carried out and the children should be directed towards suitable sports branches.

Abstract Background: The study presents an analysis of selected psychomotor abilities of female handball players at different levels of experience. Methods: Studies were performed using Test2Drive computer tests. The following four tests were used to measure psychomotor fitness: Simple Reaction Time, Choice Reaction Time, Hand-Eye Coordination and Spatial Anticipation. The study covered a group of 118 female handball players (age: 19.6 ± 3.16),who play in the PGNiG Polish Women’s Superliga, Polish 1st and 2nd handball league, for the following positions: goalkeepers, centre players, pivot players and wing players. The study also included the body composition analysis and the aerobic capacity level with the use of the multistage 20 metre shuttle run test. In addition, the level of psychomotor abilities of female handball players has been analysed depending on their competition class (league), position on the court and dominant hand. Results: The analysis of the reaction time and movement time showed statistically significant differences between the results (SIRT MT, CHORT RT,HECOR MT) obtained by the female handball players from different competition classes. Additionally, on the basis of the linear Pearson correlation were determined statistically significant relationship between psychomotor abilities and elements of body composition or the aerobic capacity level. Conclusions: The analysis showed that the female players from Polish Women’s Superliga had the highest level of reaction time (SIRT, CHORT and SPANT tests). The study also revealed a significant impact of the body mass index and the percentage of fat content on the movement time (SIRT, CHORT and SPANT tests). The aerobic capacity level (measured in the multistage 20 metre shuttle run test) had a significant influence on the reaction time.

 El siguiente estudio, tuvo como finalidad, determinar la correlación entre la composición corporal y la condición física en niños de sexto grado de la Institución Educativa de Tuluá, Colombia. El estudio fue no experimental, descriptivo y de alcance correlacional. La valoración de la composición corporal, se realizó mediante el índice de masa corporal y el porcentaje de grasa (fórmula de Slaughter y Lohmann). La condición física, se determinó por medio de la batería Fitnessgram. La muestra fue de 193 niños y niñas, entre ocho y 12 años. Los resultados se determinaron, por medio de estadísticos descriptivos y correlación de Pearson. Estos resultados, evidenciaron una r=-0,52 y -0,72 para niño y niña respectivamente, entre el porcentaje de grasa y la capacidad cardiovascular. Las correlaciones entre el índice de masa corporal y peso corporal, con el porcentaje de grasa fueron, r=0,59 niña 0,76 y niño y r=0,46 niña y 0,67 niño respectivamente, indicando que, a mayor masa corporal mayor grasa. La correlación entre masa grasa y el test de barra fija fue inversa, pero no alta, r=-0,23 y -0,24, sin embaro, cuando este test se correlacionó con el índice de masa corporal, dicha correlación fue mayor, r=-0,57 y -0,78, reflejando que, la masa corporal, afectó la resistencia en la barra. La flexibilidad y agilidad, no se alteraron por la masa grasa, r < 0,20. Como conclusión, se evidencia que, la masa grasa puede disminuir la capacidad cardiovascular y resistencia a la fuerza, sin embargo, la flexibilidad y la velocidad-agilidad pueden no alterarse.  Abstract. The following study aimed at determining the correlation between body composition and physical condition in sixth grade students from the high school Institución Educativa Moderna in Tuluá, Colombia. It was carried as a non-experimental, descriptive, and correlational study. The assessment of body composition was carried out using the body mass index and the fat percentage based on Slaughter and Lohmann formula. Physical condition was determined by using the Fitnessgram battery. The sample consisted of 193 boys and girls, around eight and 12 years old. The results were determined by means of descriptive statistics and Pearson correlation. These results showed r = -0.52 and -0.72 for boys and girls respectively, after correlating the percentage of fat and cardiovascular capacity. The correlation of their body mass index and their body weight, towards the percentage of fat were: r = 0.59 girl, 0.76 boy and r = 0.46 girl and 0.67 boy respectively, indicating that, the higher the body mass the higher the increase of fat. The correlation between fat mass and the fixed bar test was inverse, but not high: r = -0.23 and -0.24. However, when this test was correlated with the body mass index, that correlation was higher: r = -0.57 and -0.78, reflecting that the body mass affected the resistance at the bar. Flexibility and agility were not altered by fat mass: r <0.20. In conclusion, it is evidenced that fat mass can decrease cardiovascular capacity and resistance to strength, however, flexibility and speed-agility may not be altered.

LANGUAGE NOTE | Document text in English; abstract also in Chinese. The rising standard of living in Malaysia has seen changes to its population. Obesity and other diseases of wealth are appearing in younger and younger people, resulting in the need for sports or exercise to stay fit and healthy. Studies have shown an inverse relationship between body fat percentage and aerobic capacity in children (Coleman et al., 2004). However, from the general studies, little is known specifically about Chinese primary school children. Therefore, this research aims to study the body fat and aerobic capacity of Chinese primary school children in Kajang, as possible representative of the national population. It will also ascertain whether there is any gender bias in the relationship. Two hundred and forty students were studied, from Years 4 and 5, equally divided between the sexes. The body fat percentage was determined using the skinfold method on the triceps and calf. After the fat measurement, the subjects were asked to perform the PACER bleep test to assess their aerobic capacity. The boys were found to be significantly superior in aerobic capacity (t = 1.35, p < 0.18) despite having higher body fiat. There was a low negative correlation between body fat and aerobic capacity (r = -0.28, n = 240, p < 0.01) among the children which was highly significant because of the large number of samples. In conclusion, 27.50% of the subjects were founds to have moderately high to very high percentage of body fat confirming the need to exercise to stay fit and healthy among this age group, especially among the boys. 馬來西亞的人口變化提高了人們的生活水準。肥胖和其他富貴疾病都出現于少年和年輕人，導致人們必須多做運動來保持健壯-Coleman et. al., (2004)的研究證明了兒童的體脂肪率和有氧容量之間的相反關係。然而，從一般上的研究，在華小兒童兩者之間的關係明確少知。所以，此探索的目的是研究在加影區某間華小兒童的體脂肪和有氧容量，盡可能作為國家人口的代表性。借此也探知兩者之間的關係是否有任何性別偏見。研究中共有240位由4、5年級平分的男女學生參與。研究運用測量三肌肉及腓皮膚表層的方法來固定體脂肪率。測量脂肪後，受試者需履行往返距離20米的PACER測驗來估算他們的有氧容量。儘管那些男生擁有較高的體脂肪，他們卻有卓越顯著的有氧容量(t=1.35, p<0.18)。因為受試者的人數眾多，有效的反映出兒童之間的體脂肪與有氧容量有低陰性關係(r=-0.28, n=240, p<0.01)。總結來説，14.17%的受試者擁有高或很高的體脂肪率，確認了這年齡的兒童特別是男生必需做運動來保持健壯。

The aim of this study was to analyse the effects of the type of extracurricular sport on the body composition, respiratory parameters, and physical condition in prepubertal and pubertal girls. Four hundred and eighty-five female athletes (aged 8–14) from different sports participated in this study. They were gathered into four groups according to the sport typology and maturity level: ‘prepubertal girls who practise collective sports’ (PRE-CS), ‘prepubertal girls who practise individual sports’ (PRE-IS), ‘pubertal girls who practise collective sports’ (PUB-CS), and ‘pubertal girls who practise individual sports’ (PUB-IS). The cardiorespiratory fitness (the 20 m shuttle run test, 20 mSRT), anthropometry, respiratory capacity (forced spirometry), handgrip, CMJ test, and stabilometry were collected. Prepubertal girls showed a lower muscle mass (kg) and fat mass (kg) than pubertal girls regardless of the extracurricular sports typology. PRE-CS and PRE-IS also showed a lower respiratory fitness and physical fitness than pubertal girls (p < 0.05). Pubertal girls did not show significant differences (p > 0.05) in any of the body composition, respiratory fitness, and physical fitness variables when comparing between collective sports and individual sports. The results show that extracurricular participation in these types sports by prepubertal girls can influence their body composition, respiratory fitness, and physical condition.

ABSTRACT Introduction To train and prepare cadets for a career as firefighters in Rio de Janeiro, the second-year students of the Officers Training Course are submitted to a Search, Rescue, and Survival Training (SRST) course, which is characterized by long periods of high physical exertion and sleep restriction during a 9-day instruction module, and food restriction during a 7-day survival module. The present study investigated changes in the body composition of 39 male cadets submitted to SRST during training and 4 weeks of recovery with no restrictions in food consumption. Materials and Methods Each cadet was evaluated by anthropometric measurements at six time points: pre-SRST; after the first module; after the second module; and after 1, 2, and 4 weeks of recovery. Measurements included body girths and skinfolds, to estimate trunk (chest and waist) and limbs (arm and thigh) dimensions, as well as body composition. Repeated measures ANOVA and Friedman test were applied (depending on each data distribution). Results Statistically significant decreases in body weight (76.2; 69.8-87.2 to 63.9; 58.9-73.5 kg) and fat free mass (FFM, 69.2; 63.7-77.2 to 60.1; 56.2-68.0 kg) were observed following the second module of SRST. Following a single week of recovery, the FFM returned to pre-SRST values. Body weight returned to pre-training levels in 2 weeks. Body fat percentage and mass also significantly decreased during SRST (9.0; 7.7-12.3 to 6.5; 5.1-9.3% and 6.9; 5.6-10.0 to 6.9; 5.6-10.0 kg, respectively), which showed a slower and more gradual recovery that reached pre-SRST values after 4 weeks. The girths of arm, thigh, chest and waist significantly decreased due to SRST. The girths of the limbs (arm and thigh) returned to pre-training values after one month of recovery, while the girths of the trunk (chest and waist) did not return to pre-SRST values during the study period. Conclusions The findings suggest that men who experience periods of high energy demands and sleep restriction followed by a period of food restriction will endure unavoidable physical consequences that can be mostly reversed by a 1-month recovery.

This study evaluated the relationship between leg strength and endurance run performance, independent of aerobic capacity (V̇O2peak), body size, and gender, in children and adolescents with mild or moderate mental retardation. Twenty-six individuals (15 boys and 11 girls) volunteered and underwent tests of V̇O2peak, isokinetic leg strength, and endurance run performance (600-yard ran/walk and 20-m shuttle run). Results showed that leg strength was significantly related to both types of run performance; however, when controlling for V̇O2peak, body size, and gender, leg strength was a more significant contributor to the 600-yard run/walk than to 20-m shuttle run performance. Gender did not influence these relationships. These data suggest that leg strength has a significant influence on endurance run performance in children and adolescents with mild or moderate mental retardation.

Background:The purpose of this study was to assess the relationship between intensity of physical activity (PA) and body composition in 343 young women.Methods:Physical activity was objectively measured using accelerometers worn for 7 days in women 17 to 25 years. Body composition was assessed using the BOD POD.Results:Young women who spent less than 30 minutes a week performing vigorous PA had significantly higher body fat percentages than women who performed more than 30 minutes of vigorous PA per week (F = 4.54, P = .0113). Young women who spent less than 30 minutes per day in moderate to vigorous PA (MVPA) had significantly higher body fat percentages than those who obtained more than 30 minutes per day of MVPA (F = 7.47, P = .0066). Accumulating more than 90 minutes of MVPA per day was associated with the lowest percent body fat. For every 10 minutes spent in MVPA per day, the odds of having a body fat percentage above 32% decreased by 29% (P = .0002).Conclusion:Vigorous PA and MVPA are associated with lower adiposity. Young women should be encouraged to accumulate at least 30 minutes of MVPA per day, however getting more than 90 minutes a day is predictive of even lower levels of adiposity.

The Relationship

2D:4D ratio is determined by balance between androgens and estrogens. Low level estrogen reduces bone mineral density (BMD) and incurs negative changes to bone microarchitecture, increasing the risk of osteoporosis and, as a consequence, fracture risk in women. The purpose of this study was to investigate the relationship between 2D:4D, muscle strength and body composition to BMD in young women. One hundred twenty-seven young women (age range 24-36 years) voluntarily participated in this study. Lengths of the second (index) and fourth (ring) fingers, upper and lower body strength and body composition (body mass index, BMI; waist to hip ratio, WHR) and body fat percentage were estimated. Also, blood levels of calcium and 25-hydroxyvitamin D (25OHD) were evaluated and dual-energy X-ray absorptiometry device was used to measure BMD in the lumbar spine (LS) and femoral neck (FN). The results showed that digit ratios, upper body and lower body muscle strength, BMI and fat percentage had a positive relationship with LS and FN BMD (LS BMD: r=.47, r=.56, r=.46, r=.34, r=.28, p≤.001, respectively; FN BMD: r=.34, r=.49, r=.51, r=.45, r=.27, p≤.001, respectively). In addition, there was no significant relationship between WHR and BMD of LS and FN (p˃.05). Multiple linear regression analysis showed the upper body strength was a stronger determinant of LS BMD and the lower body strength was a stronger determinant of FN BMD. Based on the results, the researchers concluded that upper and lower body strength, 2D:4D ratios and BMI were important determinants of young women’s BMD. Also, it seemed that some of these factors may be able to help predicting the osteoporosis potential in young women
