Influence of Relative Age on Physical Condition and Academic Performance in Adolescents.

Annual age grouping is a common organizational strategy in academics and sports. This strategy could promote the relative effects of age, which refers to the (dis)advantages that subjects who were born in the first or last months of the year may suffer. The consequences could be minimized, resulting in better physical and/or academic results. The objective of the study was to evaluate the influence of the quarter of birth and examine the correlation between physical condition variables and academic performance. The sample included 79 students (51.90% females) 13.46 ± 0.21 years old in the second year of Obligatory Secondary Education. The physical variables of this study were explosive power, cardiorespiratory capacity, speed, flexibility, and muscle strength. They were evaluated using the horizontal jump tests, Cooper test, 50 m sprint, sit-and-reach test, and medicine ball exercises, respectively. The academic variables were obtained from the average academic grade, grouped by key competencies. An Analysis of Covariance (ANCOVA), controlling for gender, body mass, and height, revealed significant differences between male students born in the first quarter compared to those born in subsequent quarters in all physical condition variables (except for cardiorespiratory capacity). For female students, significant differences were observed only in the explosive power variable. No statistically significant intra-sex differences were evident in academic performance at any time of measurement. Additionally, moderate to large correlations were found in the physical condition and academic variables. It is concluded in relation to the need to implement diverse strategies regarding the process of developing physical conditions in adolescence that satisfy the growth needs of students based on age and sex.

Vitamin C and total soluble solid content of crystal guava at different storage duration and ripeness

Crystal guava (Psidium guajava var. 'Crystal') fruit is in great demand because of its delicious taste and high nutritional content. Storage aims to prevent postharvest damage to the fruit. However, storage that is too long causes morphological damage and decreased nutrients. This study aims to determine the effect of storage duration, fruit ripeness stage and the interaction between both factors on vitamin C and total soluble solids (TSS) content of crystal guava, and determine which treatment can produce the highest vitamin C and TSS. Fruits harvested simultaneously with three levels of ripeness based on the skin color: unripe fruit is dark green, ripe is light green, very ripe is yellowish green. Samples selected based on the same weight range. Storage was carried out for 0, 5, and 10 days at ± 10oC. The study used a completely randomized design (CRD) with a 3x3 factorial pattern with two factors: storage duration and fruit ripeness level. Parameters observed were vitamin C, TSS, weight loss, diameter shrinkage, skin color and hardness. Data were analyzed using ANOVA and DMRT. Both treatments showed an interaction on vitamin C content. The best treatment was unripe fruit stored for ten days with 14.955 ppm of vitamin C. Both treatments did not show any interaction on TSS content. The best treatment was five days storage with TSS of 8.25 °Brix and very ripe fruit of 8.21 °Brix. Based on vitamin C, TSS content, and physical condition variables, the best guava fruit is unripe fruit stored for 10 days.Keywords: color, postharvest, physical, quality, softening

The Degree of Problematic Technology Use Negatively Affects Physical Activity Level, Adherence to Mediterranean Diet and Psychological State of Adolescents.

The previous scientific literature has shown how detrimental addictive internet and mobile phone use can be for the adolescent population. However, little is known about their influence on the physical activity, kinanthropometry and body composition, nutrition patterns, psychological state, and physical fitness of this population. For this reason, the objectives of this research were (a) to determine the differences in the physical activity level, kinanthropometric and body composition variables, adherence to Mediterranean diet (AMD), psychological state, and physical fitness according to gender and different levels of problematic use of the internet and mobile phones; and (b) to establish the differences in the physical activity level, kinanthropometric and body composition variables, AMD, psychological state, and physical fitness among adolescents when considering problematic use of the internet and mobile phones in combination. The sample consisted of 791 adolescent males and females between 12 and 16 years of age (1st to 4th course) from four compulsory secondary schools (404 males and 387 females; mean age: 14.39 ± 1.26 years-old; mean height: 163.47 ± 8.94 cm; mean body mass: 57.32 ± 13.35 kg; mean BMI: 21.36 ± 3.96 kg/m2). The physical activity level (baseline score: 2.64 ± 0.67), kinanthropometric variables and body composition, AMD (baseline score: 6.48 ± 2.48), psychological state (baseline life satisfaction: 17.73 ± 4.83; competence: 26.48 ± 7.54; autonomy: 25.37 ± 6.73; relatedness: 24.45 ± 6.54), and physical condition variables were measured. The results showed that adolescent males and females with problematic internet and/or mobile phone use presented a worse psychological state, but it is especially relevant to highlight that females also had a lower level of physical activity and AMD, with problematic mobile phone use being especially relevant, mainly in the psychological state of adolescents. In conclusion, problematic use of the internet and mobile phones can have detrimental effects on the level of physical activity, AMD, and psychological state of adolescents, with the differences found in females being particularly relevant.

Analysis of Physical Resistance of Apple Tomatoes After Exposed to A Magnetic Field Extremely Low Frequency (ELF) Intensity 600 µT and 1000 µT

Apple tomatoes with the scientific name Lycopersicum Pyriporme can last 7 days at room temperature and 14 days if stored in the refrigerator. The purpose of this study was to examine the effect of the ELF magnetic field intensity 600 uT and 1000 uT for 30, 60 and 90 minutes on the degree of acidity (pH), density (ρ) and physical quality of apple tomatoes. The research design used was RAL (completely randomized design). Data collection on the pH variable begins with crushing the tomatoes and then measuring the pH value of each fruit using a digital pH meter. The density variable was obtained by weighing the mass of each fruit and dipping the fruit in 150 ml of distilled water as the initial volume, then the difference between the final volume and the initial volume was obtained to obtain the final density of each fruit using the density equation. Physical condition variables can be obtained by counting the number of good fruits and recording each measurement. Observations were made for 20 days with data collection on the 0, 4th, 8th, 16th, and 20th days. The results showed that there were differences in the value of pH, density and physical quality of tomatoes between the control group and the experimental group. Exposure to the ELF magnetic field can affect the activity and reproduction of pathogenic microorganisms in apple tomatoes so as to maintain the pH value, density and physical quality of apple tomatoes.

Adherence to the Mediterranean diet, kinanthropometric characteristics and physical performance of young male handball players.

Handball is a team sport whose performance depends on a large number of factors. The objectives of the present study were to analyze the differences in physical performance, kinanthropometric variables, and adherence to the Mediterranean diet (MD), in handball players according to sports category, as well as the possible relationships between these variables. One hundred and thirty-three male handball players (35 infant; 46 cadets; 26 juniors and 26 seniors players) underwent a kinanthropometric analysis following the ISAK protocol, self-completed the KIDMED questionnaire, and their physical condition was evaluated with different physical tests. Significant differences (p<0.001-0.007) were found between the sports categories in most of the physical condition variables and anthropometric characteristics, but not in the degree of adherence to the MD. The predominant level of adherence to the MD was medium (47.4%), followed by good (42.1%), and correlated with the body mass, the height, the BMI, the muscle mass and the ∑3-girths sum corrected, but not with physical test results. A multiple linear regression analysis showed that the fat mass and muscle mass variables had a more specific weight in the results of the physical fitness tests. There are differences according to sports category in kinanthropometric characteristics and physical fitness tests in adolescent handball players. The predominant degrees of adherence to the MD were medium and good. A relationship was found between anthropometric characteristics and physical performance in handball players.

Influence of biological maturation status on selected anthropometric and physical fitness variables in adolescent male volleyball players.

BackgroundThe identification of sport talent among adolescent athletes is a topic that in recent years has been a major focus of interest for both the scientific community and sport managers. Both anthropometry and physical performance through fitness tests have demonstrated to be key elements. Biological maturation, due to its influence on anthropometric variables and physical fitness, has also been studied in relation to sport talent identification.ObjectiveTo analyse differences according to biological maturation status in anthropometric characteristics and performance in physical fitness tests, and to determine which variables predict better performance in physical fitness tests in adolescent volleyball players.MethodsA cross-sectional design was followed to collect the data. A total of 48 male sub-elite volleyball players (14.17 ± 0.73 years) completed a socio-demographic and sports ad hoc questionnaire. Anthropometric variables were measured following the guidelines of the International Society for the Advancement in Kinanthropometry (ISAK) including four basic measurements (body mass, height, sitting height and arm span); eight skinfolds (triceps, biceps, subscapular, iliac crest, supraspinale, abdominal, thigh and calf); four girths (arm relaxed, flexed and tensed arm, middle thigh and calf); five breadths (biacromial, biileocrestal, humerus, femur and bi-styloid); three lengths (acromiale-radiale, radiale-stylion and stylion-medio dactilion); and a height (ilioespinale). Physical fitness was assessed, including the sit-and-reach, back scratch, long jump, medicine ball throw, counter movement jump (CMJ), 20 meters sprint, and agility tests. Furthermore, maturity offset and age at peak height velocity (APHV) was calculated.ResultsSignificant differences were found in the body mass (Mean Difference, MD = 20.86–30.75), height (MD = 11.72–19.09), sitting height (MD = 4.27–10.27), arm span (MD = 12.91–20.78), body mass index (MD = 3.72–5.63), upper limb length (MD = 7.76), corrected muscle girths (MD = 2.06–9.31), ∑6 and 8 skinfolds (MD = 3.67–50.21) fat mass and percentage (MD = 0.30–11.58), muscle (MD = 4.13–10.64) and bone mass (MD = 1.61–3.54) (p < 0.001–0.030), showing higher values the early maturers. In the physical fitness tests, significant differences were observed in the medicine ball throw (MD = 1.26–2.80) and in CMJ power (MD = 156.71–379.85) (p < 0.001). Regression models identified fat mass percentage predicted worse physical test performance (p < 0.001), while age, maturation offset, muscle and bone variables were predictors of better physical performance (p < 0.001).ConclusionsSignificant differences based upon the stages of biological maturation were found in the anthropometric and physical condition variables in favor of the players whose maturation process was more advanced, with the variables related to fat and adipose, muscle and bone development conditioning their performance in the physical condition tests.

Introduction: Surfing is a discipline that has considerably increased the number of followers who practice this sport. Research has focused on describing the main variables associated with performance, but not the relationships that may exist between them. Objective: To establish the relationship of dynamic postural balance with respect to the anthropometric profile and physical aptitude in surfers. Material and method: This research is an observational and cross-sectional study of a descriptive-correlational type. The sample included 30 surfers (8 women and 22 men). The variables of the anthropometric profile studied were body mass, bipedal height, body mass index (BMI), sum of folds, body composition and somatotype. Furthermore, physical aptitude was assessed by indirect tests. The data of the anthropometric profile and physical aptitude were correlated with the results of the dynamic postural balance test (Y balance test). Results: For the anterior direction of the Y balance test, the variables that were significant were gender, body weight, bipedal height, sum of folds, adipose mass and Sargent’s jump height (R2 = 0.55). The posteromedial direction of the Y balance test yielded a significant model that indicates that gender, sum of folds and adipose mass are the variables that jointly predict dynamic postural balance (R2 = 0.30). For the posterolateral direction, the model indicates that the BMI, sum of folds, adipose mass, mesomorphism, ectomorphism and performance in the sit and reach test are the variables that influence the performance of the Y balance test (R2 = 0.55). Conclusion: Predictive models were established to determine anthropometric and physical condition variables that would be decisive for the performance of a surfer’s postural balance.

Anthropometric Profile and Physical Fitness Performance Comparison by Game Position in the Chile Women’s Senior National Football Team

The aim of this study was to explore the anthropometric profile and evaluate physical fitness variables of the members of the Chile women’s national football team based on their playing positions. Fifty football players participated in this study, which was carried out during the period of training for the France 2019 Women’s World Cup and the Japan 2020 Olympic Games. Body composition and physical condition (muscular strength, sprint, agility, and aerobic fitness) were assessed. The goalkeepers showed greater weight (p &lt; 0.001), height (p = 0.002), and %Fat (p = 0.010) compared to the rest of the playing positions. There were also differences between positions in relative strength (RS) (p = 0.001), running speed at 10 and 30 m (T10 and T30, respectively), agility (AGI) (p &lt; 0.001), and yo-yo test (MYYR1) (p &lt; 0.001). RS, T10, T30, and countermovement jump (CMJ) were significantly correlated (p ≤ 0.05) with anthropometric variables (p ≤ 0.05). MYYR1 was also significantly correlated with anthropometric variables (p ≤ 0.05). In conclusion, goalkeepers show greater weight and height, as well as worse results in MYYR1, AGI, T10, T30, and RS compared to the rest of the players. Forwards present better performance in running speed and agility. Better performance in physical condition is associated with better body composition values (greater muscle mass and lower fat mass). Greater relative strength indicates greater performance in explosive actions. Therefore, to meet the demands of high competition, it is important to establish ideal profiles in anthropometry and physical condition variables based on the playing position.

Intervention program in childhood education for physical fitness work

One of the main causes of coronary, respiratory and metabolic diseases among others, in today’s society, is sedentary life. Sedentarism comes from the high rate of abandonment of physical-sport practice in the period of adolescence. The consolidation of healthy habits from an early age, including the daily practice of physical activity, is essential to improve adherence over time. The main objective of this study was to carry out a motor intervention program in an infant education class in order to improve their physical condition-health. Nineteen infants (10 boys, 9 girls) aged 3 years participated in this study. The intervention was conducted over a period of 6 weeks. Families were also made aware about the importance of physical activity. Anthropometric variables of height and weight were measured, as well as physical condition variables such as speed and long jump, before and after the intervention. The Kolmogorov-Smirnov test revealed the normality of the sample which allowed a comparison of means with Student’s t-test. The results obtained in the physical tests reveal that the physical condition of the participants improved ostensibly, although this improvement was only statistically significant in the case of the 4x10 test. Nevertheless, the work in this line shows a positive tendency towards the improvement of the physical condition-health, thus education professionals are expected to continue working in this direction.

Identifying Predictors of the Visceral Fat Index in the Obese and Overweight Population to Manage Obesity: A Randomized Intervention Study

Introduction: Nowadays, obesity is one of the main causes of death and disability. In recent years, it has been shown that the excess and distribution of body fat increases morbidity, with excess visceral fat being the most important factor that triggers pathologies. Thus, estimation of visceral fat makes it possible to identify patients with a higher cardiovascular risk, aiding the management of obesity. The main objective of the study was to identify predictors of the visceral fat index through a lifestyle intervention and to observe the effect of the intervention on dietary habits and functional capacity. Methods: A randomized intervention, parallel-group study was made. This study included 97 obese and overweight people (control group, n = 48; experimental group, n = 49) with a low socioeconomic status in an 8-month lifestyle intervention. Anthropometric, fitness and nutritional tests were assessed. Results: It was found that being female, eating the recommended daily portions of fruit, gaining strength in the legs and gaining flexibility are factors predictive of a lower visceral fat index. Age over 45 years and eating the recommended weekly portions of cereals and meats, fat and processed meats increases the visceral fat index after a lifestyle intervention. There were changes in the visceral fat index and in the different physical condition variables, but not in eating habits. Conclusion: A multicomponent lifestyle intervention reduces the visceral fat index; age over 45 and consuming cereals and meat increases the visceral fat index.

PENGARUH STRES KERJA DAN KONDISI FISIK KERJA TERHADAP KINERJA DOSEN DAN TENAGA KEPENDIDIKAN PADA SEKOLAH TINGGI ILMU EKONOMI AMA SALATIGA

Abstrak Human resources as organizational assets are very decisive in the success of organizations including the STIE AMA Salatiga. The participation of the lecturers and education staff cannot be released in order to achieve the stated goals. Lecturers and education staff who are working require adequate physical work conditions and not high levels of stress to be able to perform better. The study was conducted to determine the effect of work stress and physical work conditions on the performance of lecturers and education staff at the AMA Salatiga College of Economics. The results of the study are expected to be an input for STIE AMA Salatiga in taking policies in an effort to improve the performance of lecturers and education staff, and are expected to have an impact on achieving the Function, Vision, Mission and Objectives of STIE AMA Salatiga. Based on the results of data analysis, researchers can draw conclusions about the effect of work stress and physical work conditions on the performance of lecturers and education staff at STIE AMA Salatiga as follows: The results of the validity test and reliability test show that each item statement and each research variable are declared valid and reliable. While the results of the partial test of work stress variables do not have a significant effect on the performance variables, while the physical condition variables work significantly influence the performance variables. Then simultaneous testing of work stress variables and physical conditions of work has a significant effect on performance variables. The coefficient of determination (R Square) is 0.20, this means that the independent variables of work stress and physical conditions of work can explain the dependent variable of performance by 20% and the remaining 80% explained by other factors not examined.

Lifestyle and physical condition factors associated with gender-specific BMI in Spanish preadolescents

Obesity has become one of the most serious health problems in our society and is associated with a multitude of conditions and complications at puberty. Through this descriptive, cross-sectional study we intended, first, to know the differences by gender in lifestyle and physical condition variables, and second, to know the determinants related to lifestyle and physical condition for a Spanish population aged 10 to 12 years with a medium socioeconomic status. The variables analyzed were BMI, physical condition variables (agility, flexibility, and cardiorespiratory capacity), and health habit variables (quality and frequency of food, physical activity, sedentary lifestyle, and sleep duration). We found significant differences between girls and boys in food quality and frequency, physical activity, sedentary lifestyle, flexibility, and maximum oxygen consumption variables. In the predictive analysis, the models significantly predicted the BMI for the total sample, the group of boys, and the group of girls. Explanatory variables include quality of breakfast, sedentary lifestyle, VO2 max and agility.

Características morfofuncionales y motoras de los seleccionados deportivos de la Universidad del Valle

Estamos convencidos de que el Sistema Nacional del Deporte estudiantil debe convertirse en el mejor instrumento para promover y articular la detección temprana de talentos, especializar la práctica y focalizar y priorizar la intervención estatal y privada en esta materia; igualmente, las decisiones de política deben privilegiar los procesos de perfeccionamiento, cualificación y competición de los mejores deportistas, hasta hacerlos parte del deporte asociado y de los calendarios deportivos, regionales, nacionales e internacionales. En tal sentido, se establecieron las características morfológicas, funcionales y motoras de los seleccionados de la Universidad del Valle, por deporte y sexo, como criterio para la selección, planeación de las cargas de trabajo y control del proceso de entrenamiento, de tal forma que se pueda garantizar la vinculación de los deportistas mejor dotados al sistema del deporte universitario y, por ende, al deporte asociado, con lo que se espera lograr una verdadera conexión que el país deportivo desconoce. Para el efecto, fueron valorados 125 deportistas de ambos géneros, 62,4 % hombres y 37,6 % mujeres, seleccionados al azar y pertenecientes a 12 modalidades que forman parte de los seleccionados de la universidad, según registro del Centro Deportivo Universitario (CDU). Los métodos empleados para el estudio fueron: las medidas antropométricas se establecieron mediante el método de ISAK, el porcentaje de grasa y el tejido magro estuvieron determinados por bioimpedancia, con el empleo de una báscula Tanita TBF-310, el tiempo de desplazamiento se midió mediante la carrera de 30 m salida parada, la potencia de miembros inferiores, con el test de Abalakov (ABK), la potencia aeróbica máxima, con el empleo del test de Leger y la agilidad, con el test de Illinois. En el análisis de componentes principales, cuatro factores explican el 89 % del total de la dispersión en mujeres, donde el primer factor se encuentra conformado por el porcentaje de grasa, el porcentaje de músculo y el tiempo para la distancia de 30 m; el segundo factor se relaciona con las longitudes y la masa corporal; el tercer factor, por la agilidad y el IMC; y el cuarto, por la potencia aeróbica máxima y la potencia anaeróbica aláctica. En el caso de los hombres se observa una mejor asociación entre los factores y las modalidades deportivas. El primer factor representa la masa y el porcentaje de músculo, asociados con deportes como atletismo, futsal y fútbol; un segundo factor recoge la potencia anaeróbica aláctica y la estatura y, finalmente, el tercer factor se asocia con la potencia aeróbica, la agilidad y el IMC. El análisis de medias no mostró diferencias significativas entre los deportes, excepto en la carrera de 30 m, motivo por el cual, se elaboraron tablas de calificación para las variables antropométricas y de condición física por género, uniendo en una sola las clasificaciones de los deportes individuales y colectivos.

Health-related physical condition variables in university students

The aim of this study was to assess the health of individuals over a sample of university students, by measuring variables related to fitness as a basis for reorienting physical activity programmes offered by the university sports services to optimise healthy physical condition of its users. We developed a descriptive study with a sample of 217 students of the University of Vigo applying battery tests AFISAL-INEFC variables measuring health-related physical condition variables: body composition, muscular strength, flexibility and maximal oxygen uptake. Since not all variables are normally distributed we used the nonparametric tests Mann-Whitney U and Chi-Square (χ2), using a significance level of p <0.05. The results showed that in the hand-grip variables, peak oxygen consumption and lower body explosive power, women had a higher percentage of individuals with low fitness. The opposite situation occurred with the variable of trunk flexibility and hamstring muscles where men showed a lesser capacity. From a global view, the lower body explosive strength was the variable in which the university had a worse condition with 65.3% of subjects with low fitness. It would be positive to increase healthy physical activity programmes promote exercise in our target population (university students), particularly those affecting strength capacity and flexibility in both upper and lower body.

Impact of walking ability and physical condition on fatigue and anxiety in hematopoietic stem cell transplantation recipients immediately before hospital discharge

PurposeThis study analyzed the influence of walking ability and physical condition on fatigue and anxiety at hospital discharge in patients receiving hematopoietic stem cell transplantation (HSCT). MethodA total of 25 subjects were assessed after receiving HSCT until discharge. The Japanese Cancer Fatigue Scale and the State-Trait Anxiety Inventory were used to assess fatigue and anxiety. Relationships of fatigue and anxiety status respective to walking ability variables: leg muscle strength (knee extension, ankle plantar flexion and ankle dorsiflexion strength) and average number of daily steps, and physical condition variables (food intake, febrile days, body mass index, and serum albumin) were examined with correlations and stepwise multiple regression analysis. ResultsSubjects with later achievement of adequate food intake after HSCT (β = 0.62) and weaker knee extension strength per body mass at discharge (β = −0.42) reported higher fatigue (adjusted R2 = 0.53, p = 0.00). Knee extension strength per body mass at discharge was correlated with an average step-count from 51 to 80 days after HSCT (r = 0.51, p = 0.01). In subjects whose Body Mass Index was above 23.5, weaker ankle dorsiflexion strength per body mass prior to transplantation reported higher fatigue at discharge (adjusted R2 = 0.97, p = 0.00). Subjects with later achievement of food intake after HSCT (β = 0.59) and more days with fever reported higher anxiety (adjusted R2 = 0.47, p = 0.00). ConclusionPost-HSCT fatigue was affected by a delay in adequate food intake and diminished muscle strength. The results of this study show the importance of encouraging walking for maintaining muscle endurance.

Nipple feeding for preterm infants with bronchopulmonary dysplasia.

To examine the influence of an infant's physical condition on nipple-feeding practices and the contribution of the infant's age at complete nipple feeding to dietary intake and somatic growth outcomes. A retrospective, correlational study. Two Level III nurseries. Records of 55 preterm infants with bronchopulmonary dysplasia. The infant's intake of kcal/kg on Day 1 of complete nipple feeding and the weight gain per day between complete nipple feeding and discharge. Gestational age and days on mechanical ventilation, continuous positive airway pressure, or supplementary oxygen influenced age at start and at completion of nipple feeding (p < .05). The infant's weight when nipple feeding was introduced was the primary determinant of age at introduction of nipple feeding (B = .50, p < .001). The physical condition variables did not influence the transition time from introduction of nipple feeding to complete nipple feeding. Neither the physical condition variables nor the feeding practice variables contributed to caloric intake. Weight gain between the time of complete nipple feeding and hospital discharge was less for infants who were on supplementary oxygen longer and who were older when completely nipple fed (p < .01).
