Delayed Growth

This article addresses the problem of whether high-impact artistic gymnastics training could cause delayed growth in young male and female athletes, as is believed to be the case in professional dancers. The main anthropometric characteristics of young gymnasts were measured, and the differences between gymnasts, swimmers, and nonathletes were examined. Twenty competitive gymnasts, 20 competitive swimmers, and 20 nonathletes, aged 10 to 12 yrs old, volunteered to participate in this study. Testing took place in a training field and the equipment consisted of portable anthropometric instruments. Measurements concerned body mass, stature, segment lengths (arm, forearm, trunk, thigh, and calf), body breadths (biacromical, biiliac, wrist, and ankle), circumferences (arm and thigh), and skinfold thicknesses (arm, thigh, and calf). Triceps and calf skinfold thicknesses were used to estimate the body fat percentage (%BF). The lean body mass percentage (%LBM) and the LBM/BF ratio were also evaluated. Moreover, cross-sectional areas of the arm (CSAarm) and thigh (CSAthigh) were calculated, taking into consideration the limb's circumference and four circumferential skinfolds. The results showed that, generally, young male and female gymnasts had smaller body dimensions in some anthropometric characteristics compared to swimmers and nonathletes. This mainly focused on body weight, arm and calf lengths, biiliac/biacromial breadths ratio, skinfold thicknesses, and %BF. However, gymnasts had higher %LBM, LBM/BF ratio, and CSAarm. No significant differences were found in the rest of body dimensions and composition. Although young male and female gymnasts appeared to have some lower anthropometric characteristics compared to the other two groups, it has not clearly demonstrated a delay in their somatic growth and skeletal development.

Abstract The purpose of this study was to establish the anthropometric and physical profiles of elite young soccer players according to their playing position, and to determine their relevance for the selection process. One hundred and fifty-six young male soccer players participated in the study. Players were classified into the following groups: Goalkeepers (n=16), Central Defenders (n=26), External Defenders (n=29), Central Midfielders (n=34), External Midfielders (n=28), and Forwards (n=23). Anthropometric variables of participants (body height, body mass, body mass index, 6 skinfolds, 4 diameters, and 3 perimeters) were measured. Participants performed the Yo-Yo test, sprint tests (30 m flat sprint and Balsom agility test) and 2 jump tests (countermovement jump and the Abalakov test). At the end of the season, the technical staff of the club selected some of the players to continue playing on the same team and the rest were not selected. The results show that heavier and taller outfield players performed better in vertical jumps and sprint tests, whereas leaner outfield players performed better in the Yo-Yo test. Fat percentage of selected players was lower than that of the non-selected ones. The rest of the body components were similar in the selected and non-selected players within each playing position. Moreover, the selected players performed slightly better than the non-selected players in the physical test, but these differences were not statistically significant.

Objective The objectives were to analyze the body composition and body functions of the freestyle ski half-pipe national team athletes, to understand the body composition characteristics of the athletes , and to explore the relationship between body composition and body function in the sports program, in preparation for 2022 The Winter Olympics provides a theoretical reference. Methods 9 members of the freestyle ski half-pipe national team were used as subjects (average age 15.78±0.97, exercise age 6.38±2.75), and they were tested and analyzed using an ultrasonic body composition tester and Wingate anaerobic power bike. Body composition test indicators: body fat rate, lean body mass. Body function test indicators: maximum anaerobic power.  This paper uses literature, experimental and mathematical statistics. And the mathematical statistics method: using SPSS 2.0 to analyze the data by Pearson correlation. Results 1. The body fat rate of male and female athletes in freestyle half-pipe national team was: 7.60±1.16; 19.75±1.25. The lean body mass of male and female athletes was: 53.8±1.85KG; 44.75±0.62KG. The maximum anaerobic power of male and female athletes in freestyle half-pipe national team was: 453.80±17.87; 345.50±3.01. The lean body mass of male athletes was significantly positively correlated with the maximum anaerobic power (r=0.995, P<0.01). Female athletes' lean body mass was positively correlated with maximum anaerobic power, but not significant. There is no correlation between the body fat rate and the maximum anaerobic power of male and female athletes in the freestyle ski half-pipe national team. Conclusions 1. Freestyle ski half-pipe players have a positive correlation between lean body mass and anaerobic capacity.  According to the characteristics of the sports program, the higher lean body weight has a positive impact on improving the athletic ability and thus ensuring the completion of difficult movements.       2. Due to the relationship between athletes' age and sample size, the data in this paper is only a recommended reference for this sports program. It is not applicable to all programs. It is necessary to continue to supplement the data to establish a body composition evaluation system for the freestyle ski half-pipe team.

While studies on large samples of recreational runners have often relied on participants’ self-reported height and body mass, the validity of these data have not been investigated for this population. Hence, this study sought to examine the validity of self-reported anthropometric measures among recreational marathon runners. Female ( n = 32) and male ( n = 135) recreational marathon runners were requested to estimate their body mass and height (and we calculated their self-reported body mass index [BMI]), after which we took actual measures of their body mass and height and calculated their actual BMI. Participants’ self-reported values underestimated their actual body mass by 0.65 kg ( p < .001, η2 = 0.222) and their actual BMI by 0.35 kg ⋅ m−2 ( p < .001, η2 = 0.245). There was a significant Assessment Method × Sex Interaction for both body mass ( p = .019, η2 = 0.033) and BMI ( p = .017, η2 = 0.034), as women underestimated body mass values more than men. Participants overestimated their height by 0.44 cm ( p < .001, η2 = 0.075), but the interaction of sex and assessment method for height was not statistically significant. Underestimates of body mass correlated with marathon racing speed ( r = .24, p = .006) and body fat percentage ( r = −.29, p = .001) in men, but not in women ( p > .05). The disagreement between self-reported and measured anthropometric data in the present sample was lower than has been previously reported for the general population, suggesting that marathon runners may more accurately self-perceive and/or report their anthropometric characteristics. These findings are of practical value for health professionals and researchers (e.g., nutritionists and exercise physiologists) questionnaires to recreational marathon runners.

Background and Study Aim: The aim of this research was to determine the differences between the young soccer players (U19) in terms of anthropometric characteristics and body composition. We considered players of three the most successful clubs in three countries of the southern region of the Balkan Peninsula. Material and Methods: The first sub-sample of the subjects was consisted of 17 players of OFC Titograd from Montenegro of the average age 17.12±.69. The second sub-sample was consisted of 14 players of FC Siroki Brijeg from Bosnia and Herzegovina of the average age of 18.14±.86. The last sub-sample of the examinees was consisted of 15 players of FC Feronikeli from Kosovo of the average age 18.07±.46. Anthropometric characteristics in the body composition were evaluated by a battery of 11 variables. The significance of the differences between the young soccer players in the anthropometric characteristics and variables for assessing body composition were determined by ANOVA and LSD Post Hoc test. Results: The young soccer players of the three mentioned clubs have statistically significant differences by the two variables that estimate the upper leg skinfold and fat percentage. The young soccer players of OFC Titograd are significantly better in variable upper leg skinfold than other players. The young soccer players of FC Feronikeli are significantly better in variable fat percentage than players of OFC Titograd. Conclusions: The results can be useful for coaches of other clubs for making a comparison of their soccer players with the young soccer players in this research.

Rapid weight loss or “weight cutting” is a common but potentially harmful practice used in mixed martial arts competition. Following the official weigh-in, competitors refeed and rehydrate themselves in a process known as rapid weight gain (RWG) to realize a potential competitive advantage. While data from surveys and small series have indicated the majority of mixed martial arts athletes engage in rapid weight loss, there is a lack of officially collected data from sanctioning organizations describing its prevalence. The present investigation represents a summary of the data collected between December 2015 and January 2018 by the California State Athletic Commission. In total, 512 professional mixed martial artists (455 males and 57 females) were included. Of these, 503 (98%) athletes gained body mass between weigh-in and their bouts. Total RWG between weigh-in and competition was 5.5 ± 2.5 kg, corresponding to an 8.1% ± 3.6% body mass increase. Total RWG was 5.6 ± 2.5 kg (8.1% ± 3.6%) for males and 4.5 ± 2.3 kg (8.0% ± 3.8%) for females. More than one quarter of men and one third of women gained >10% body mass between weigh-in and competition. Athletes from leading international promotions gained more absolute, but not relative, body mass than those from regional promotions. Our findings indicate RWG is nearly ubiquitous in professional , with a similar prevalence in male and female athletes. Trends based on promotion suggest a larger magnitude of RWG in presumably more experienced and/or successful mixed martial artists from leading international promotions.

Error Of Measurement

Body dimensions and body composition of children participating in artistic activities, such as gymnastics and many types of dancing, are important factors in performance improvement. The present study aimed to determine the reliability of a series of selected anthropometric measurements in young male and female gymnasts. Segment lengths, body breadths, circumferences, and skinfold thickness were measured in 20 young gymnasts by the same experienced examiner, using portable and easy-to-use instruments. All parameters were measured twice (test-retest) under the same conditions within a week's period. The high intra-class correlation coefficient (ICC) values ranging from 0.87 to 0.99, as well as the low coefficient of variation (CV) values (<5.3%), affirmed that the selected measurements were highly reliable. The technical error of measurement (TEM) values for lengths and breadths were 0.15 to 0.80 cm, for circumferences 0.22 to 1 cm, and for skinfold thickness 0.33 to 0.58 mm. The high test-retest ICC and the low CV and TEM values confirmed the reliability of all anthropometric measurements in young artistic gymnasts. Therefore, these measurements could contribute to further research in this field of investigation, helping to monitor young artistic gymnasts' growth status and identify specific characteristics for increased performance in this sport.

 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.
