Mapping biological activity of soils using the ‘Life in Undies’ citizen science programme
In 2021, Institute for Soil Sciences, HUN-REN Centre for Agricultural Research launched ‘Life in Undies’, the first Hungarian citizen science project with the aim of obtaining information on the biological activity of soils through a simple estimation procedure. Hungarian adaptation of the international ‘Soil your Undies’ programme gained decomposition data from 1078 site countrywide by getting buried standardised cotton underwear for 60 days, at…
Prevalence and Risk Factors of Problematic Internet Use among Hungarian Adult Recreational Esports Players
Background: Esports are highly prevalent in modern culture, particularly among young people, and are a healthy hobby for the majority of users. However, there is a possible link between video gaming (including esports) and problematic internet use (so-called internet addiction, IA), mostly involving adolescents. Methods: Here we present an online survey focusing on the prevalence and risk factors of internet addiction among adult esports players.…
Estimation of the drought sensitivity of Hungarian soils based on corn yield responses
During our soil-specific drought sensitivity research, an aim of ours was to ascertain how drought, a stress factor caused by the lack of precipitation, affects soil fertility. We used the five-year-long (1985–1989) soil and corn yield data of the National Pedological and Crop Production Database (NPCPD). We assigned the annual Pálfai Drought Index (PaDI) to the annual corn yield data of the NPCPD in order to identify drought-free corn yields and…
The Relationship between Body Fat Percentage and Some Anthropometric and Physical Fitness Characteristics in Pre- and Peripubertal Boys
The main aim of this study was to compare anthropometric and physical fitness indicators of boys of the same chronical age but with different fat percentages. Subjects were Hungarian boys aged 9−13 years ( N = 6919). Anthropometry was measured according the guidelines of the International Biological Program. Relative body fat was estimated by Drinkwater−Ross's method (1980); Conrad's growth type of physique was also estimated (1963). Physical fit…
Body Mass and Body Fat in Hungarian Schoolboys: Differences between 1980–2005
The prevalence of juvenile excess weight keeps growing in the more developed world (WHO, 1998). The aim of the study was to compare the prevalence of overweight and obesity in Hungarian schoolboys in 1980 and 2005.Two independent representative data collections were performed in volunteer boys aged between 6.51 and 18.50 years in the same 90 settlements of the country in 1980 (n=13,061) and 2005 (n=13,060). Height, body mass, and five skinfolds w…
Longitudinal differences and trends in body fat and running endurance in Hungarian primary schoolboys
Long-range repeated-measure sample differences in body dimensions, body composition and physical performance are considered accurately describing the changes in a population's life standards and lifestyle. The aim of our study was to analyse such changes in longitudinal studies repeated after a 15-year interval. Two six-monthly repeated data collections (1987-1991 and 2002-2006, respectively; n = 136 and n = 147, respectively) were carried out in…
Activity-Related Changes of Body Fat and Motor Performance in Obese Seven-Year-Old Boys
The effects of 35 weeks of extra-curricular, mainly aerobic, dynamic physical activity were analysed in overweight and obese 7-year-old boys contrasted with control groups. Body composition was estimated by using the body mass index (BMI) and skinfold thicknesses. Overweight or obesity was defined according to the suggestions of Cole and associates (2000). The activity program consisted of swimming and water games, folk dance, and soccer. Data we…
Changes over Four Years in Body Composition and Oxygen Uptake of Young Adult Males after University Graduation
Lifestyle changes and challenges following university graduation often present a sharp contrast to the relatively free and basically pleasant university life enjoyed by the typical college student. Adaptation to a new work environment, relocation to a new community, concerns of marriage and family, personal finances, including income and budgeting (automobile and mortgage payments, savings, etc.), and adjustment to independent living result in an…
Direct and indirect interrelations between anthropometric and physiological variables in athletic and non-athletic adolescent girls: A Path-Analytic Study
Our previous analysis of anthropometric and exercise test data of 62 athletic and 56 non-athletic girls (age range 10.5-15.5 years) showed that the intensity of habitual exercise failed to discriminate between the group means of the studied variables. However, the patterns of intervariable correlations differed between the subgroups categorized by physical activity. The present paper studies the problem of this difference further by using explora…
