The Effect of the Cranial Electrotherapy on the Muscle Motor Function in Different Operating Modes
The aim of the present study was to analyze the effect of cranial electrotherapy stimulation on muscle function analysis indicators. Instrumental assessment of muscle function (on a REV9000, Technogym, Italy) was performed before and after cranial electrotherapy stimulation, assessments of the muscle function was performed during knee extension maximum voluntary, isometric contraction (MVIC), angle velocity with load 45Nm isotonic contraction and maximum pick torque in isokinetic contraction on 30°/s, 200°/s and 300°/s and neuromuscular efficiency measurements. To analyze data was used Excel program Statistics 3.1. Subjects of our study were twenty healthy athletes of sport fitness. 1 minu…
Changes in Placental Morphology and their Association with Embryonic Skin Development
Abstract Histogenesis and organogenesis in mammals normally transpires in a hypoxic environment. Oxygen diffusing capacity is dependent on diffusion distance, which may vary with the thickness of placental barrier and with the level of tissue vascularity. Since the epidermis is avascular, its development fully depends on dermal blood vessels. Despite the large number of studies focusing on uteroplacental circulation and embryogenesis, it is clear that the current knowledge of how placental changes in pregnancy contribute to skin development is incomplete. The aim of this study was to evaluate the association between structural changes in the placental barrier and development of the integume…
Analysis of Body Composition of 9- and 10-Year-Old Children in Latvia
Background and Objective. According to the data of epidemiologic research, the prevalence of both excessive and insufficient body weight is increasing in a pediatric population leading to the growing burden of health problems due to these changes. The aim of the study was to understand the current situation of physical development of 9- and 10-year-old boys and girls in Latvia and to estimate the prevalence of underweight, normal weight, overweight, and obesity among young adolescents. Material and Methods. During 2007–2009, a random sample of healthy 9-year-old (n=184) and 10-year-old (n=320) children from all regions and different socioeconomic groups of Latvia was surveyed in a cross-sec…
A Cross-Sectional Research on the Height, Weight and Body Mass Index of Children Aged 5-6 Years in Latvia and Its Secular Changes during the Last Century
Aim: To determine the main anthropometric parameters and their changes during the 20th and early 21st centuries for children aged 5-6 and to analyze the nutritional level of the population based on percentage. Methods: 536 healthy Latvian 5 and 6 year old children were randomly selected and a cross sectional survey was carried out. To collect anthropometric data, the height and weight of each child was measured and BMI calculated. The Kolmogorov-Smirnov Goodness-of-Fit test was used to assess the distribution of data; it was concluded, that the data for both boys and girls in both analyzed age groups fits a normal distribution. Using a t-test statistical tool, the results were compared to o…
