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.

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.

The first purpose of the present study was to test sensitivity of the Wingate anaerobic test (WAnT) to alterations in resistance settings. The second purpose was to investigate whether using optimal braking force on WAnT enhances its relation with a 50-m dash, a vertical jump (VJ), or a standing long jump (LJ) tests. Twenty-three 12 year-old boys performed a 50-m dash, VJ, LJ, and WAnT using four braking force resistances (BFR; .065, .070, .075, and .080 kp/kg BM). Results revealed significant (p ≤ .05) differences among the four BFRs in peak power (PP) and in mean power (MP). Post hoc tests indicated significant differences among all of the four BFRs in PP and between the 0.065 and both the 0.075 and the 0.08 kp/kg BM in MP. Results of Pearson correlation coefficients indicated that using the optimal BFR for both PP and MP enhanced their relation with performance during the 50-m dash, VJ, and LJ tests. Also, partial correlation coefficients, controlling for body weight, height, percent fat, or body mass index supported these findings. It was concluded that for untrained, healthy 12-year-old boys, WAnT is sensitive to incremental alterations in resistance settings ranging from 0.065 to 0.080 kp/kg body mass. To be more specific, PP is sensitive to small increments in BFR, while MP is only sensitive to larger increments in BFR. Furthermore, optimizing resistance settings on WAnT enhances its relationship with anaerobic performance tasks, such as the 50-m dash, the VJ, and the LJ.

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.

This study examined temporal trends in body mass index (BMI) among United States adults with intellectual disability (ID) participating in Special Olympics from 2005 to 2010. In addition, the prevalence of obesity was compared with published National Health and Nutrition Examination Survey (NHANES) statistics. After data cleaning, 6,004 height and weight records (male = 57%) were available from the Special Olympics International Healthy Athletes Health Promotion database for the calculation of BMI. Rates of overweight and obesity were very high but generally stable over time. Compared with NHANES statistics, the prevalence of obesity was significantly higher for Special Olympics female participants in each data collection cycle. Integrated efforts to understand the social, environmental, behavioral, and biological determinants of obesity and among Special Olympics participants are needed.

The purpose of this study was to determine where men fall on the motivation continuum based on intuitive eating status and if motivation for physical activity and intuitive eating are correlated. Results indicate that being an intuitive eater was associated with a lower body mass index. In terms of demographic variables, as age increased, intuitive eating status decreased and body mass index increased. Men scored high on the antidieting and self-care subscales of the Intuitive Eating Scale. Men who were classified as intuitive eaters scored higher on the external and introjected regulation of the Behavioral Regulation in Exercise Questionnaire but no significant differences were reported by eating status and the identified and intrinsic motivation subscales. Intuitive eating holds promise as a weight management and weight loss tool for men. Intuitive eating may also influence initial motivation for physical activity for men.
