We aimed to model endurance, explosive power, and muscle strength in relation to body mass index (BMI) and physical-fitness tests in Greek children aged 7–10 years old. In the present large epidemiological study, anthropometric measurements and physical-fitness tests (i.e., multistage shuttle run, vertical jump, standing long jump, small ball throw and 30-m sprint) from 141,169 children were analyzed. Age- and sex-specific normative values for physical fitness tests were expressed as tabulated percentiles using the LMS statistical method. The correlation coefficients between BMI and performances were negative and significant for both sexes (p < .01) in all physical-fitness tests. The only exception was a positive correlation between ball throw and BMI (p < .01). Only 2.9% and 4.0% of boys and girls respectively, passed the upper quartiles in all tests. The performance in speed may serve as a predictive factor explaining, at least in part, the performance in aerobic endurance and explosive power in children aged 7–10 years. The presented population-based data for physical-fitness tests revealed that only a small percentage of these children are in the upper quartiles in all tests. Furthermore, the data suggests that speed performance can be used to predict physical fitness.

The lifestyle and diet of today's modern society can lead to overweight and obesity. Overweight and obesity is now beginning to worry. This study aims to provide a description of the condition of Body Mass Index (BMI) and physical fitness among adolescents in Bangka Belitung Islands in 2017, and how BMI and physical fitness are associated. 105 adolescents were participants of this study, 90 male and 15 female adolescents. Participants aged ± 18 years in the year of the study conducted. Anthropometry is performed to identify participants' BMI. Performance tests were conducted to identify the components of physical fitness related to the health of the participants. Performance of vertical jump (leg power), sprint 60 meter (speed), push-up (strength and endurance of arm muscle), sit-up (strength and endurance of abdominal muscles), and run / walk distance 1000/1200 meters (cardiorespiratory endurance). BMI has a significant correlation with the strength and endurance of arm muscle (t = 3.79, p < 0.05). BMI has a significant correlation with leg power (t = 4.97, p < 0.01). BMI correlates significantly with speed (t = 4.04, p < 0.05). CRE is only significantly correlated with abdominal muscle strength and endurance (t= 2.51, p < 0.01). Overweight and obesity can be prevented through the provision of a program of physical activity that meets the rules of physical fitness. The program should be provided from primary to senior high school and it’s a sustainable long-term program at every level of education at school. Hopefully overweight and obesity can be prevented.

(1) Background: Parental feeding practices are related to child body mass index (BMI, kg/m2) and seem to be a consequence rather than cause of child BMI, but research so far is limited. Stability and continuity of feeding practices, probably explaining changes in food intake and child BMI, remain to be poorly examined. (2) Methods: Feeding practices (i.e., restriction, food as reward, pressure to eat, monitoring) assessed via the Child Feeding Questionnaire, child age, standardized BMI (zBMI), and socio-economic status were measured annually at multiple visits (range 2–8) in a population-based longitudinal cohort study of 1512 parents with their children aged 2 to 12 years. Stability, continuity, and bi-directionality of feeding practices and child zBMI were calculated using correlation coefficients, paired t tests, and cross-lagged panels, respectively. (3) Results: Feeding practices and child zBMI showed moderate to high stability. While continuity was high for restriction, minor temporal changes were observed for other feeding practices and child zBMI. Cross-lags indicated that child zBMI predicted restriction, pressure to eat, and monitoring, while food-rewarding predicted child zBMI only minorly. (4) Conclusions: Parents seem to adapt feeding practices to child zBMI with the exception of food-rewarding.

Background: The scientific research into the varied factors that influence cricket performance has become a focal area for overall improved performance. Although there has been documented evidence for both anthropometry and physical fitness among elite cricketers, there is a paucity of evidence among the club cricket cohort. This pilot study aims to evaluate the anthropometric and fitness measurements among a pilot sample of university club cricketers (n = 17; 9 batsmen and 8 bowlers) in South Africa. Methods: Retrospective data were collected from the university’s male first cricket team of the 2019/2020 season. The data included both anthropometric (height, body mass, and body mass index) and physical fitness (explosive power, strength, Yo-Yo, speed and agility) parameters. The results exhibited for every parameter were presented according to height categories and player positions (batsman and bowler). Student t-tests were performed to determine the differences between fitness and anthropometric variables among both height categories and player positions. All data were analysed using SPSS (Version 26, IBM). The level of significance was set at p<0.05. Results: The results indicated significant differences for height categories with regards to stature (p = 0.000) and agility (p = 0.03). Significant differences were also evident for different player positions with regards to body fat percentage (p = 0.02) and vertical jump distance (p = 0.03). Conclusions: The findings of this pilot study indicated that cricketers who are shorter in stature are less superior with regards to anthropometric and fitness capabilities than their taller counterparts. In addition to being aware of the variances that exist for anthropometry, stature and fitness among cricketers at any level; this study provides implications for both coaches and sports scientists at the club level (under-researched level) in terms of how this can translate to player performances in accordance to height categories and player positions.

The objective of this study was to investigate physical fitness of preschoolaged children just before entering school according to their body mass index, and to examine possible associations of body mass index, fat mass and fat-free mass with physical fitness in preschool-aged children. Two hundred and fifty-six preschoolers aged 6 to 7 years participated in the study. Physical fitness was assessed using PREFIT test battery and body composition was estimated using four skinfold thickness parameters. Overweight children had lower cardiorespiratory fitness and lower results in all weight-bearing fitness tests, and better handgrip strength test result in comparison with normal-weight children. Significant associations were found between body composition indices and the results of physical fitness tests. Higher BMI associated negatively with weight-bearing physical fitness tests. The results of the research indicate that weight-status and body composition have significant effect on physical fitness in 6–7 years old preschoolers.

AbstractObjectivesPhysical inactivity and poor physical fitness in children and adolescents are growing public health problems globally. This study aimed to investigate the correlation between Body Mass Index (BMI) and three physical fitness components, including overall fitness, according to the Swedish Physical power, Mental harmony and Social capacity profile (FMS profile). Another aim was to investigate the test-retest reliability of the FMS questionnaire and fitness tests.MethodsA total of 3,692 male and female adolescents in Sweden, between year 2004 and 2013, aged from 16 to 18 years old, were included. Height and weight data were collected to calculate the Body mass index (BMI). The participants performed physical fitness tests, which measure cardio-respiratory fitness, muscular strength and flexibility. The test-retest study included 18 adolescents, aged 16. They answered the FMS questionnaire and participated in the fitness tests with one-week interval.ResultsA weak inverse relationship between BMI and physical fitness was found: r=−0.06 to −0.07 (p<0.05) for flexibility, r=−0.13 to 0.10 (p<0.001) for strength, r=−0.14 to −0.33 (p<0.001) for cardiorespiratory fitness, and r=−0.15 to −0.27 (p<0.001) for overall fitness. In the test-retest study, the ICC’s for strength, flexibility and balance were 0.94, 0.96 and 0.89, respectively. The ICC’s for the questions regarding lifestyle ranged from 0.75 to 1.00 and for diet, physical activity and drugs were 0.56, 0.44 and 0.58, respectively. The correlation was stronger in overweight/obese individuals compared to normal weight individuals.ConclusionOverweight and obese individuals scored lower in the fitness tests compared to their normal weight counterparts. The test-retest study revealed that the FMS questionnaire and fitness tests are reliable tools.

The Relationship

Taekwondo is a martial sport that relies on kicks. For a taekwondo athlete to kick, it is necessary to support the explosive power of the leg muscles. This study aims to analyze the relationship between age, sex, body mass index, length of exercise with leg muscle explosive power in taekwondo athletes. Subjects and Methods: This analytic descriptive study used a cross sectional design. The subjects of the study were taekwondo members at Sangkuriang Sports Hall and Lions Gymnasium in Cimahi City, West Java Province, totaling 95 people. The dependent variable is leg muscle explosive power. The independent variables were age, gender, body mass index and duration of exercise. The instruments used are questionnaires and vertical jump measuring instruments. Data were analyzed bivariately using OR and chi square test. The explosive power of the limbs increased with increasing age (OR= 2.89; 95% CI= 1.23 to 5.77; p= 0.010) and duration of exercise (OR= 7.44; 95% CI= 2.96 to 18.67; p <0.001). Leg explosive power decreased with body mass index but not statistically significant (OR= 0.72; 95% CI= 0.30 to 1.18; p= 0.600). Gender increased limb explosive power, but not statistically significant (OR= 1.14; 95% CI= 0.51 to 2.56; p= 0.900). The explosive power of the limbs increases with age and duration of exercise. The relationship between limb explosive power and sex and body mass index was not statistically significant

The Relationship

The study aims to assess the relationship between the body structure, physical fitness, and functional parameters of the respiratory system of the cadets from the General Tadeusz Kościuszko Military University of Land Forces (AWL) and their results in passing selected obstacle courses. The research material was collected from testing cadets of the third year of management studies. The research included anthropometric measurements, physical fitness tests, spirometry, and tests determining the level of passing selected obstacle courses. Body height and weight were measured. The body mass index was also calculated. Besides, the following functional characteristics were measured: cardiopulmonary endurance, functional strength, running speed and agility, balance, forced expiratory volume in 1 second, forced vital capacity, and peak expiratory flow. The study also included tests determining the level of passing the land and water obstacle courses. Statistically significant relationships were found between height and weight, balance, and forced expiratory volume in 1 second. Moreover, there were correlations between body weight and body mass index and the results in passing the land obstacle course. In addition, there were connections between cardiopulmonary endurance and performance in passing the land obstacle course, body balance, and performance in passing the land and water obstacle course. All the relationships mentioned above were low and statistically significant.

Coordination Disorder

We investigated whether children with suspected Developmental Coordination Disorder (DCD+) demonstrate different physical fitness levels compared with their normal peers (DCD−). Randomly recruited Greek children (n = 177) were assessed for body mass index (BMI), flexibility (SR), vertical jump (VJ), hand strength (HS), 40m dash, aerobic power, and motor proficiency. ANCOVA revealed a motor proficiency (i.e., DCD group) effect for BMI (p < .01), VJ (p < .01), and 40m speed (p < .01), with DCD+ children demonstrating lower values than DCD−. Differences between DCD+ and DCD− were also obtained in log-transformed HS (p < .01). These findings suggest that intervention strategies for managing DCD should also aim at physical fitness increases.
