Swimming speed depends on anthropometric characteristics, biomechanics factors, physical fitness, physiological components, and genetics. Therefore, this study aimed to identify which anthropometric characteristics influence swimming speed in adolescent competitive swimmers. Thirty-eight male swimmers (aged 16.94 ± 0.8 years; body height: 178.3 ± 5.4 cm; body weight 67.7 ± 9.6 kg) and thirty-five female swimmers (aged 17.12 ± 0.7 years; body height: 175.1 ± 6.6 cm; body weight 59.9 ± 7.1 kg) participated in the study. All swimmers have competed at the national level in Serbia for at least three years and have at least five years of training experience. Fifteen variables were measured: arm length, hand length, leg length, foot length, seat height, wrist diameter, ankle joint diameter, elbow diameter, chest circumference, triceps skinfold, forearm skinfold, abdominal skinfold, subscapular skinfold, thigh skinfold, calf skinfold. The measurements were taken by the Martin anthropometer, Omron digital scale BF511, and John Bull caliper. Swimming speed was measured during 50-m and 100-m front crawl swimming. Multiple regression analysis revealed that arm length, wrist diameter, and chest circumference, all together, accounted for 77% of 100-m front crawl swimming speed in male swimmers, while abdominal skinfold accounted for 90% of 100-m front crawl swimming speed in female swimmers. Results showed that anthropometric characteristics could not account for adolescent swimmers' 50-m front crawl swimming speed. However, anthropometric characteristics can influence the result in swimming (100-m front crawl swimming speed) in adolescents and thus should be considered a diagnostic tool in selecting young swimmers.

CrossFit is recognized as one of the fastest-growing high-intensity functional training modes in the world. The study aimed to compare the effects of the CrossFit training program and traditional gym training on anthropometric measurements in healthy, active men. The study sample consisted of 50 participants who were divided into two groups, 22 participants who practiced the CrossFit training program (CFT group; 28.64±2.04 years; body height 181.74±6.96 cm; body mass: 72.75±5.53 kg), and 28 participants who applied traditional gym training (GT group; 26.89±2.99 years; body height: 184.52±7.80 cm; body mass: 74.86±8.48 kg). A total of ten anthropometric measurements (Body height, Body mass, BMI, Subscapular, Abdominal and Triceps skinfolds, Chest, Forearm, Upper arm, and Thigh circumferences) were monitored before and after twelve weeks. The Shapiro-Wilk test was used to test the normality of distribution. The multivariate analysis covariance (MANCOVA) and analysis of covariance (ANCOVA) were used to analyze the data. The results of this study indicated that there were statistically significant differences between groups in the Circumference of the upper arm (p=0.02), Thigh circumference (p=0.00), Chest circumference (p=0.03), and Subscapular skinfold (p=0.00). The findings of this study demonstrated that healthy, active males who participated in the 12-week CrossFit training program improved their anthropometric measurements more than those who trained in the traditional gym training.

Six motor tests were applied on a sample of 48 children (33 boys and 15 girls) 5 and 6 years of
age (± 6 months), who attended sports school twice a week, in duration of one hour. The primary
objective of this study was to determine differences in motor skills of preschool children. Results
of multivariate multi-factor analysis of variance (MANOVA) show no statistically significant
differences in the overall system of analyzed motor variables in relation to gender and age
regarding the studied sample of children. Analysis of individual motor skills, using the procedure
of univariate multi-factor analysis of variance (ANOVA), revealed no statistically significant
differences in relation to gender and age factors. With respect to the age factor, a statistically
significant difference was obtained for variables: 20 meters dash, obstacle course backwards and
standing broad jump, in favor of the 6-year old children. With respect to the gender factor, a
statistically significant difference existed only for the variable seated straddle stretch in favor of
girls.
