Body Height and Its Estimation Utilizing Arm Span Measurements in Serbian Adults

Los antropologos estimaron la altura de las naciones en los Alpes Dinaricos hace mucho tiempo. Como los Serbios modernos caen en la clasificacion racial de Dinaricos, el proposito de este estudio fue examinar la altura corporal en adultos serbios, asi como la relacion con la longitud de la envergadura de brazo a brazo como una alternativa a la estimacion de la altura corporal, que varia en los diferentes grupos etnicos y raciales. Se analizo a 394 estudiantes (318 hombres y 76 mujeres, con edades entre 20,13±1,47 anos y 19,59±1,46 anos, respectivamente) de la Universidad de Novi Sad. Las medidas antropometricas fueron tomadas de acuerdo con el protocolo de ISAK, obteniendo Medias y DE. La comparacion de la media de altura corporal y envergadura dentro de cada grupo y entre sexos se realizo con la prueba t. Las relaciones entre estatura y envergaduras se determinaron mediante coeficientes de correlacion simple, con un intervalo de confianza del 95%. Tambien se realizo un analisis de regresion lineal para examinar el grado en que la envergadura puede prever con exactitud la altura corporal. Los resultados mostraron que los hombres Serbios tienen una altura de 181,96±6,74 cm, y una envergadura de 184,78±8,41 cm, mientras que las mujeres una altura de 166,82±5,88 cm y una envergadura de 164,67±8,09 cm. En comparacion con otros estudios, estos resultados demuestran que para ambos sexos, la poblacion Serbia es una de las mas altas. Por otra parte, la envergadura predice confiablemente la altura corporal en ambos sexos. Sin embargo, las ecuaciones de estimacion obtenidas en esta poblacion son sustancialmente diferentes a otras poblaciones, ya que la envergadura fue cercana a la altura corporal: en hombres 2,82±4,89 cm mayor a la altura corporal y en mujeres 2,15±4,68 cm menor a esta. Esto confirma la necesidad de desarrollar diferentes modelos de para determinar la altura en cada poblacion.

Comparative Study of Anthropometric Measurement and Body Composition between Elite Soccer and Basketball Players

El proposito de este estudio fue describir las caracteristicas antropometricas y de composicion corporal de los jugadores de futbol y basquetbol de elite, asi como hacer comparaciones entre ellos. Setenta y un hombres fueron incluidos en el estudio, divididos en tres grupos: 26 jugadores de futbol, 14 jugadores de basquetbol y 31 sujetos sedentarios sanos. Todos los sujetos fueron evaluados para obtener las medidas antropometricas requeridas para el calculo de las variables de composicion corporal, utilizando los procedimientos normalizados recomendados. Los datos fueron analizados mediante el programa SPSS y los datos estadisticos descriptivos se expresaron como media (desviacion estandar) para cada variable. Ademas se utilizaron las pruebas de ANOVA y LSD que se llevaron a cabo para detectar los efectos de cada tipo de deporte. Los resultados mostraron que no existia diferencia significativa en el indice de masa corporal entre los grupos, mientras que se encontro una diferencia estadisticamente significativa para la altura del cuerpo y el peso corporal, asi como para las tres variables medidas del cuerpo (musculo, hueso y grasa) entre los grupos. Los jugadores de basquetbol fueron significativamente mas altos y pesados que los jugadores de futbol y los sujetos del grupo de control, mientras que tambien hubo una diferencia significativa entre el peso de los jugadores de futbol y los sujetos del grupo de control, que fueron significativamente mas pesados. El contenido muscular y oseo de los sujetos en el grupo control fue significativamente menor, mientras que no hubo diferencias entre los jugadores de futbol y baloncesto. Por ultimo, el contenido de grasa en el cuerpo de los sujetos en el grupo de control fue significativamente mayor que la de los otros sujetos, mientras que no hubo diferencia entre los jugadores de futbol y de basquetbol. Por lo tanto, estos hallazgos pueden dar a los entrenadores de la region un mejor conocimiento y sugerir a ellos seguir los ultimos metodos de proceso de seleccion y ser mas cuidadoso durante el reclutamiento.

An Examination of the Ethnicity-Specific Prevalence of and Factors Associated with Substance Use and Misuse: Cross-Sectional Analysis of Croatian and Bosniak Adolescents in Bosnia and Herzegovina

Substance use and misuse (SUM) in adolescence is a significant public health problem and the extent to which adolescents exhibit SUM behaviors differs across ethnicity. This study aimed to explore the ethnicity-specific and gender-specific associations among sports factors, familial factors, and personal satisfaction with physical appearance (i.e., covariates) and SUM in a sample of adolescents from Federation of Bosnia and Herzegovina. In this cross-sectional study the participants were 1742 adolescents (17–18 years of age) from Bosnia and Herzegovina who were in their last year of high school education (high school seniors). The sample comprised 772 Croatian (558 females) and 970 Bosniak (485 females) adolescents. Variables were collected using a previously developed and validated questionnaire that included questions on SUM (alcohol drinking, cigarette smoking, and consumption of other drugs), sport factors, parental education, socioeconomic status, and satisfaction with physical appearance and body weight. The consumption of cigarettes remains high (37% of adolescents smoke cigarettes), with a higher prevalence among Croatians. Harmful drinking is also alarming (evidenced in 28.4% of adolescents). The consumption of illicit drugs remains low with 5.7% of adolescents who consume drugs, with a higher prevalence among Bosniaks. A higher likelihood of engaging in SUM is found among children who quit sports (for smoking and drinking), boys who perceive themselves to be good looking (for smoking), and girls who are not satisfied with their body weight (for smoking). Higher maternal education is systematically found to be associated with greater SUM in Bosniak girls. Information on the associations presented herein could be discretely disseminated as a part of regular school administrative functions. The results warrant future prospective studies that more precisely identify the causality among certain variables.

Differences in Anthropometric Characteristics, Somatotype Components, and Functional Abilities Among Young Elite Kosovo Soccer Players Based on Team Position

The height, weight, diameters, volumes and skin folds were measured on a sample of 242 young soccer players from the Republic of Kosovo and therefore, the body composition, somatotype components, BMI index and maximum oxygen consumption. These were indirectly measured in order to determine their common morphological and functional features and analyz e specificity i.e., the likely differences based on the playing positions (goalkeepers, defense, middle players and attackers). W ithin the statistical analysis, the basic descriptive statistical parameters were calculated, and a multivariate and univariate analysis of v ri nce and post-hoc analysis were applied. Goalkeepers have statistically significantly higher body height and humeral breadth, and lower v lues of maximum oxygen consumption, in comparison to players who play the other positions on the team and higher body weight regarding the players who play in the middle and the attackers. Defense players have statistically significant higher body weight than the mi ddle players. In the other anthropometric measures and somatotype components, there are no statistically significant differences amo ng th players who play on different positions in the team. The achieved results could serve as normative morphological and functional indicat rs for regular sports medical examinations of young soccer players in the Republic of Kosovo. They could also be used as a templat e for comparison of the morphological and functional data of young soccer players at similar level in different countries.

Body mass index of montenegrin athletes participating in U21 national basketball team

Skiing is one of the more well known winter sports which may cause wounds. The target of this examination was to distinguish the most well-known kinds of wounds in Iran’s biggest ski resort. This cross-sectional unmistakable examination was performed on 1233 of patients admitted to the Dizin Resort Infirmary in 2008- 2009. Acquired information included age, sex, injury type and clinical intercessions. All information were investigated by SPSS 16.0 programming.Background: Osteoarthritis is the most prevalent joint condition in the world . The knee is the primary large joint affected by the disease. Obesity has been shown to both cause and exacerbate osteoarthritis and is the most notable risk factor which can be modified . There is evidence to endorse weight reduction as a treatment for osteoarthritis .There is also good evidence showing that education and Exercise interventions can reduce pain and increase physical ability.I will discuss the three models of human movement, the inverted pendulum model, the spring-mass model and the integrated spring-mass model (ISMM). The (ISMM), which integrates the spring suspension systems of the foot and shoulder region as well as the torsion spring of the spine and the mass, the head. I will discuss my clinical findings show compressive disorders like TOS and herniated discs are merely an over control of tension on the human spring mechanism leading to these syndromes. I will give brief review of the symptoms and their patterns, the common orthopedic tests, and diagnostic tests, the 16 different common conservative therapies and the 10 reasons for when surgery is medically necessary. I will discuss an alternative treatment for this disorder based on the integrated spring mass model.Introduction Traumatic-induced stresses provoke an alteration in hemodynamic parameters and neurohormonal indices. These changes can be pathologically deteriorated following chronic repetitive head trauma. In this regard, head trauma may cause irreversible metabolic and hormonal changes leading patients disability and lowering quality of life [1, 2]. Another major of point to be mentioned is Boxing nature that has repetitive head trauma and high-intensity *Corresponding author: Yasaman Keivanchehr, Tabriz University of Medical Science, Iran.

BDNF also exert a key role in learning and memory abilities. Furthermore, reduced levels of BDNF have been linked to depression, anxiety and the physiopathology of neuropsychiatric and neurodegenerative conditions such as Schizophrenia and Parkinsons disease, respectively. Importantly, peripheral BDNF levels have been used as a biomarker in several clinical studies, since this neurotrophin is able to cross the blood-brain barrier in a bi-directional manner and seems to present a strong correlation with the central nervous system fluid levels. Experimental and clinical studies have demonstrated that different exercise protocols remarkably increase BDNF levels in both healthy and patient populations. However, this response in well-trained individuals has been poorly explored. Among the various categories of physical activity available, running is probably the oldest performed by humans. Therefore, this study aimed to investigate the effect of regular running practice on BDNF levels in plasma of middle-aged (aged 30-50 years old) and elderly (aged ≥ 60 years old) healthy individuals. Then, amateur runners (EXE groups) and sedentary individuals (SED groups) were submitted to a basal blood collection (15 ml). Plasma BDNF levels were determined by the ELISA method, from Sigma–Aldrich commercial kit (catalog number RAB0026) according to the manufacturer’s instructions. A significant increase in BDNF levels in EXE individuals compared to the SED group was observed in both groups, young and elderly (p=0.036, p=0.007, respectively). These findings might suggest that the increased levels of BDNF might be linked to runners’ phenotype, regardless of age.

Body Height and its Estimation Utilizing Arm Span Measurements in Macedonian Adults

Abstract The purpose of this study is to examine body height in Macedonian adults as well as its relationship with arm span, as an alternative to estimating body height. A total of 239 students (114 men and 125 women) participated in this study. The anthropometric measurements were taken according to the protocol of ISAK. The relationships between body height and arm span were determined using simple correlation coefficients at a ninetyfive percent confidence interval. Then a linear regression analysis was performed to examine extent to which arm span can reliably predict body height. Results displayed that male Macedonians are 178.10±6.79cm tall and have an arm span of 178.78±7.71cm, while female Macedonians are 164.58±5.40cm tall and have an arm span of 164.41±6.42cm. The results have shown that both genders made Macedonians a tall nation but not even close to be in top tallest nations. Moreover, the arm span reliably predicts body height in both genders.

Stavovi prema reklamiranju u sportu u odnosu na učestalost posmatranja sportskih događaja

Cilj ove studije se odnosi na provjeravanje i analiziranje stavova potrosaca prema reklamiranju u sportu u odnosu na ucestalost posmatranja sportskih događaja, dok je uzorak ispitanika obuhvatio 433 punoletna građanina koji su bili podijeljeni na sljedece entitete, prije svega one koji, uopste ne posmatraju sportske događaje, zatim one koji ih posmatraju od jednog do 30 minuta, 31–60 minuta, 61–90 minuta, 91–120 minuta, kao i one koji sportske događaje posmatraju vise od 120 minuta tokom uobicajenog dana. Uzorak promjenljivih je sacinjavao sistem od tri suda, a ispitanici su ih ocjenjivali prema sedmo-stepenoj Likertovoj skali vrijednosti. Od statistickih procedura, koriscene su multivarijatna analiza varijanse (MANOVA), univarijatna analiza varijanse (ANOVA) i LSD Post Hoc test putem kojih je utvrđeno da se znacajne razlike između subuzoraka pojavljuju na multivarijatnom nivou kao i kod sve tri promjenljive na nivou znacajnosti od p=.05. Rezultati su pokazali da ispitanici koji ucestalije posmatraju sportske događaje imaju znacajno pozitivnije stavove prema reklamiranju u sportu, u odnosu na ispitanike koji uopste ne posmatraju sportske događaje, ali i na ispitanike koji posmatraju sportske događaje u maloj mjeri.
