Effects of regular sport activities on stress level in sporting and non-sporting university students.

Background: Regular sport has favourable influence on the physical and mental state. Our aim was to analyse the relationship between regular sport activities, body parameters, cortisol level, perceived stress and the frequency of psychosomatic symptoms in male and female university students.

Methods: Subjects were university students (N = 200).

A proposal for the adjustment of bone mineral density for body dimensions in children.

The precise age estimation is of high importance in bone mineral density (BMD) assessment in children, since the bone structure of a studied child is evaluated by using the age and gender dependent references. In addition, the biological age - the bone age in this case - estimation could help this bone structural evaluation process, since the developmental status of the skeletal system can significantly alter from the theoretical developmental status determined by chronological age in healthy, but early or late maturing children. The aims of the study were (1) to check whether volumetric BMD (vBMD) Z-scores estimated by considering chronological age and biological age differ significantly in children aged between 7-18 years, and (2) in the case of significant inaccuracy of Z-score estimation based on chronological age to construct new vBMD standards adjusted for body developmental status.

Physiological and Psychological Responses to a Maximal Swimming Exercise Test in Adolescent Elite Athletes.

Background: Continuously rising performances in elite adolescent athletes requires increasing training loads. This training overload without professional monitoring, could lead to overtraining in these adolescents.

Methods: 31 elite adolescent athletes (boys: = 19, 16 yrs; girls: = 12, 15 yrs) participated in a field-test which contained a unified warm-up and a 200 m maximal freestyle swimming test.

Body structural and cellular aging of women with low socioeconomic status in Hungary: A pilot study.

Objectives: The health status of an individual is determined not only by their genetic background but also by their physical environment, social environment and access and use of the health care system. The Roma are one of the largest ethnic minority groups in Hungary. The majority of the Roma population live in poor conditions in segregated settlements in Hungary, with most experiencing higher exposure to environmental health hazards.

The body composition analysis as a complementary tool in the screening of bone structural abnormalities.

. The importance of early diagnosis, bone-healthy lifestyle and medication is required for remaining fracture free. Dual-energy X-ray absorptiometry and ultrasound densitometry are widely used to screen osteoporosis and other bone structural diseases.

[The prevalence of psychosomatic complaints among 8-17-year-old Hungarian children].

Introduction: Subjective health complaints are common among children as well. Age, gender, health status, etc. can modify the prevalence, intensity, frequency and the dimensions of the psychosomatic complaints.

The association of psychosomatic health with physical status and lifestyle factors in adolescence.

The main purposes were to analyse the age pattern of experiencing psycho-somatic complaints in children; to study the influence of physical status and lifestyle factors on psycho-somatic status. The sample (n: 13,331, aged 7-18) represented a subsample of the 2 Hungarian National Representative Growth Study. Subjects were divided into underweight, normal, preobese and obese subgroups.
