The Relationship

The objectives of this study were: (i) to analyse anthropometric parameters and throwing speed from seven meters in amateur male handball players of different ages; (ii) to know the relationship between anthropometric parameters and throwing. One hundred seventy-six male handball players (16.5 ± 5.1 years old) participated in the study, classified according to their age: senior (n = 35), U18 (n = 30), U16 (n = 37), U14 (n = 50) and U12 (n = 24). All participants were evaluated by anthropometric measurements (height, weight, body mass index, arm span, hand width) and throwing speed from 7 m standing. A one-way analysis of variance with a Bonferroni post hoc test was used to establish the differences between teams. Pearson’s simple correlation coefficients were calculated between analyse anthropometric parameters and throwing speed. Multiple linear regression was used to predict the throwing speed. Only BMI was related with throwing speed in all age groups (0.506 > r < 0.813, p < 0.05). Throwing speed was predicted (24–72%) with only one or two variables in each model. The selected variables were: BMI, arm span in U16 model and height U14 model, and the BMI, arm span and height are proved to be good predictors of TS in male handball players.

The Relationship

Background and Aims: Cord blood leptin may reflect the leptinemic status of a newborn at birth more accurately than the leptin values of blood collected from other sites. The present study was undertaken to determine the relationship of cord serum leptin concentration at birth with neonatal and maternal anthropometric parameters. Materials and Methods: Blood was taken from the umbilical cord of the babies at delivery. Maternal anthropometric measurements were recorded at admission for delivery. Neonatal anthropometric measurements were recorded within 48 hours after delivery. Linear regression analysis was used to explore the relationship between cord serum leptin concentration and anthropometric parameters of the baby and the mother. Both Serum leptin and serum C-peptide levels were measured by chemiluminescence-based ELISA method. Results: The leptin concentration (ng/ml, mean±SD) in cord blood was 39.13±14.44. Cord leptin levels correlated with birth weight (r=0.673, p<0.0001), ponderal index (r=0.732, p<0.0001) but it did not correlate with maternal body mass index, gestational age (r=0.135, p=0.349) at delivery or cord serum C-peptide concentration (r=-0.049, p=0.735) or placental weight (r=0.203, p=0.157). Conclusion: There are associations between cord leptin concentration at delivery and birth weight, ponderal index (PI) of the babies but not body mass index (BMI) of the mothers. High leptin levels of the baby could represent an important feedback modulator of substrate supply and subsequently for adipose tissue status during late gestation.

The Relationship

BACKGROUND Although millions of overweight and obese adults use mobile phone apps for weight loss, little is known about the predictors of success. OBJECTIVE The objective of this study was to understand the relationship between weight loss outcomes and weekly patterns of caloric intake among overweight and obese adults using a mobile phone app for weight loss. METHODS We examined the relationship between weekly patterns of caloric intake and weight loss outcomes among adults who began using a weight loss app in January 2016 and continued consistent use for at least 5 months (N=7007). Unadjusted and adjusted linear regression analyses were used to evaluate the predictors of percentage of bodyweight lost for women and men separately, including age, body mass index category, weight loss plan, and difference in daily calories consumed on weekend days (Saturday and Sunday) versus Monday. RESULTS In adjusted linear regression, percentage of bodyweight lost was significantly associated with age (for women), body mass index (for men), weight loss plan, and differences in daily caloric intake on Mondays versus weekend days. Compared with women consuming at least 500 calories more on weekend days than on Mondays, those who consumed 50 to 250 calories more on weekend days or those with balanced consumption (±50 calories) lost 1.64% more and 1.82% more bodyweight, respectively. Women consuming 250 to 500 calories or more than 500 calories more on Mondays than on weekend days lost 1.35% more and 3.58% more bodyweight, respectively. Compared with men consuming at least 500 calories more on weekend days than on Mondays, those consuming 250 to 500 calories or more than 500 calories more on Mondays than on weekend days lost 2.27% and 3.42% less bodyweight, respectively. CONCLUSIONS Consistent caloric intake on weekend days and Mondays or consuming slightly fewer calories per day on Mondays versus weekend days was associated with more successful weight loss.

Purpose: The purpose of this study was to investigate the mediating effect of optimism on the relationship between grit and learning flow in nursing college students. Methods: Structured self-reported questionnaires were used to measure grit, optimism and learning flow. The study was conducted on 200 nursing students in P, U and J cities between September 1 and September 20, 2020. The data were analyzed using a t-test, one-way ANOVA, Pearson’s correlation coefficients and hierarchical multiple linear regression with SPSS/WIN 23.0. Results: Significant relationships were found between learning flow and grit (r=.60, p<.001), between learning flow and optimism (r=.42, p<.001), and between grit and optimism (r=.42, p<.001). Additionally, optimism had a partial mediating effect on the relationship between grit and learning flow (Z=3.11, p<.001). Conclusion: These results indicate that interventions to increase the level of grit along with optimism is necessary in order to increase the level of nursing college students’ learning flow.

The purpose of this paper is to presents results from two empirical surveys concerning selected factors which can be connected to customer orientation, performance and competitiveness of firms. The purpose of the surveys was also to reveal potential differences between sectors arising from not only the different influences of internal but as well as external environment. A survey instrument was developed to analyse the relationship between several variables measuring customer orientation of surveyed firms and between these factors and level of financial performance. Several statistical methods were applied to analyse the data, specifically descriptive statistics (means and standard deviations), one-way analysis of variance (ANOVA) with Bonferroni post-hoc test using financial performance for clustering firms and for assessment of potential differences of customer orientation criteria evaluation and Spearman rank correlation coefficients to assess the linear bivariate relationship between customer orientation variables. The results of ANOVA show that only the innovativeness is distinctive distinguishing criteria in conformity with the indicators of financial prosperity and that there are some differences between companies from two groups of sectors within the managers’ perception of customer orientation criteria performance.

The purpose of this research is to examine standing height in both Kosovan genders as well as its association with foot length, as an alternative to estimating standing height. A total of 1623 individuals (830 male and 793 female) participated in this research. The anthropometric measurements were taken according to the protocol of ISAK. The relationships between body height and foot length were determined using simple correlation coefficients at a ninety-five percent confidence interval. A comparison of means of standing height and foot length between genders was performed using a t-test. Then a linear regression analysis was carried out to examine extent to which foot length can reliably predict standing height. Results displayed that Kosovan male are 179.52±5.96cm tall and have a foot length of 26.22±1.19cm, while Kosovan female are 165.72±4.93cm tall and have a foot length of 23.52±1.01cm. The results have shown that both genders made Kosovans a tall nation but not even close to be in top tallest nations. Moreover, the foot length reliably predicts standing height in both genders; but, not reliably enough as arm span.

The Relationship

Physicians, who provide general medical services, should give the patients an advice on physical activity. The study was aimed to assess physical activity of medical students, as well as their awareness of this issue, and willingness to provide the public an advice on commitment to a healthy lifestyle in terms of physical activity. A total of 518 medical students were surveyed. The data obtained with the Steps and Screen Time mobile applications were used. Physical fitness was assessed using the standard anthropometric technique. Statisctical processing of the data obtained was performed with the Statistica 13 PL statistical software package. The study met the requirements of biomedical ethics and posed no risk to participants. No significant differences in the number of steps between males and females was observed. It was 9033±3297 steps in males and 7807±3570 steps in females. The evidence supporting the relationship between physical activity and average time spent on a smartphone per day was obtained: the correlation coefficient for the relationship between the number of steps per day and the screen time was -0.36 (moderate negative correlation). Correlation coefficients for the relationships between body mass index and physical activity (-0.35) and between body mass index and screen time (0.33, moderate positive correlation) were calculated. The data obtained allowed us to develop simple and feasible guidelines on improving physical activity in medical students, as well as to develop a tracker of positive habit of daily optimal physical activity for each student, and to discuss the results within the framework of the business game Physical Activity in Various Sectors of Population.

The aim of this study was to provide percentile values for a cardiorespiratory fitness (CRF) field test for Latin-American adolescents (34,461 girls and 38,044 boys) aged 13 to 15 years. The role of fatness parameters on the CRF level across age groups was also examined, with a focus on non-obese (healthy) and obese groups. CRF was assessed using the 20-meter shuttle run test protocol. Anthropometric parameters were measured using body mass index z-score (body mass index (BMI) z-score), BMI, waist circumference (WC), and waist-to-height ratio (WHtR). Participants were categorized according to the BMI z-score, WC, and WHtR international cut-off points as healthy and obese. Age- and sex-specific reference tables for the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th centile scores were calculated using Cole’s lambda, mu, and sigma method. The prevalence of obesity according to the BMI z-score, WC, and WHtR was 9.6%, 11.2%, and 15.0%, respectively. Across all age and sex groups, a negative association was found between relative peak oxygen uptake ( V ˙ O2peak) and BMI, WC, and WHtR. In boys and girls there were higher levels of performance across all age groups, with most apparent gains between the ages of 13 and 14 years old. Overall, participants categorized in the healthy group had shown to have significantly higher V ˙ O2peak than their obese counterparts (p < 0.001; Cohen’s d > 1.0). In conclusion, our study provides age- and sex-specific reference values for CRF ( V ˙ O2peak, mL·kg−1·min−1). The anthropometric parameters were inversely associated with CRF in all ages in both sexes. The obese group had worse CRF than their healthy counterparts independent of anthropometric parameters used to determine obesity.

This study aimed to analyze the relationship between perceived aquatic competence (PAC) and real aquatic competence (RAC) in 6 to 10 year old children in skills identified as relevant for surviving an aquatic accident. The study sample consisted of 105 children (8.2 + 1.3 years old). Two age groups were examined separately [G1, 6 to 7 years (n = 53); G2, 8 to 10 years (n = 52)]. Children’s aquatic competence was evaluated twice for skills linked to the risk of drowning: Firstly, using a common swimsuit (simple condition) and secondly wearing a t-shirt (complex condition). The PAC was assessed by questionnaire interview. Pearson correlation coefficients, pairwise, and independent t-test comparisons were performed with a significance level of 5%. Similar levels of PAC were found among both age groups for all measured skills, excepted for breath control during swimming (p < 0.05). However, PAC differs significantly (p < 0.001) from RAC (in simple and complex conditions) only in G1. Correlations between PAC and RAC were modest for all measured skills in both age-groups. Significant differences were found between RAC in simple and complex conditions in both groups (p < 0.01). Age contributes to a higher perceived aquatic competence in skills related to the risk of drowning.
