    Influence of high physical load endurance exercises on the anthropometric parameters and health status of military personnel
    (EDP Sciences, 2018) Plavina, Liana; Vellere, Natalija; Umbrasko, Silvija; Berķis, Uldis; Vilka, Lolita; Rīga Stradiņš University
    Military personnel are in high-risk group for health disorders, musculoskeletal pathology and psychological overload. We provide evaluation of the anthropometric parameters and health status of military personnel, Cadets, who have participated in ten days duration Combat training course. Combat training course is associated with life-style change – social, environmental, climate and geographical conditions, biorhythms, nutrition etc., with an increase in physical and psych emotional loads. It is characterized with transition from daily routine of military study process in National Defence academy to military exercise in external environment. Cadets faced to feeding limitation, sleeping deprivation intensive and continuous training, strict discipline etc. We provided analysis of anthropometric parameters before, and in time of Combat training course, summarized data of health statement and health problems that were fixed in the medical cards. The proper body mass supports good health capacity and we provided assessment of it. Physical fitness and body composition have adverse effect on military performance. Body composition undergoes changes during higher physical load performance. Military personnel have high risk to health, concerning impact of external and internal factors. According the review of medical cards of cadets group, we indicated main problems, which are fixed after the Combat training course.

    Longitudinal Analysis of Latvian Child Growth : Anthropometric Parameters Dynamics from Birth to Adolescence
    (2024-04-03) Umbraško, Silvija; Martinsone-Berzkalne, Liene; Plavina, Liana; Cauce, Vinita; Edelmers, Edgars; Starikovs, Aleksandrs; Vetra, Janis; Institute of Anatomy and Anthropology; Statistics Unit
    This study provides a comprehensive analysis of the physical development patterns from birth to adolescence, utilizing a longitudinal dataset of 70 children monitored from birth until 17 years of age. The research focuses on the variability of growth trajectories, emphasizing the role of genetic and environmental factors in influencing these patterns. Key findings indicate that most children undergo one or two periods of accelerated growth, with significant variability in the timing and magnitude of these growth spurts. The study also highlights the adaptive nature of growth changes over generations, influenced by ecological, nutritional, and socio-economic conditions. The longitudinal approach reveals critical insights into the timing of peak growth velocities, demonstrating that girls reach their growth peak approximately one year earlier than boys. The analysis of intergenerational growth patterns suggests a significant increase in average height over the century, attributed to genetic diversity and changes in lifestyle and nutrition. This study’s findings emphasize the importance of updating physical development standards regularly to reflect the changing genetic and environmental landscape. The variability in growth patterns and their correlation with health outcomes in later life highlights the need for targeted public health strategies that address the underlying socio-economic and environmental determinants of health. This research contributes to the understanding of physical development trajectories and provides a foundation for future studies aimed at optimizing health outcomes from early childhood through adolescence. The primary objective of this article is to meticulously analyze the dynamics of height growth and accurately identify the periods of accelerated bodily development within the context of longitudinal research.

    Physical Activity and Life Quality of Part-Time Students
    (Latvia University of Life Sciences and Technologies, 2018) Plavina, Liana; Karklina, Helena; Dišlere, Vija; Rīga Stradiņš University
    Physical activities are important for everyone in order to keep the physical preparedness and support an adequate level of life quality. Physical activities of young people – students are basis for keeping health capacity, working ability, developing business and carrier, and providing economic and social stability. Sport activities are very popular nowadays. Anyone can choose various sport activities that are suitable and available, that favour physical fitness and increase health status. Physical activities usually are planned during leisure time and weekends. We have provided a questionnaire about physical activities of student groups in period from 2012 till 2016. Studies have indicated the number of smokers, assessed results of questionnaire about physical activity, the body mass, body heights, and anthropometric indices. Results reflected that general physical activity level (in scores) in examined groups – part time students – were low for female and moderate for male. Recent research suggests that a significant percentage of students didn’t get adequate physical activity. We fixed increased numbers of individuals of both genders who have no any sports activity in the last years. The mean value of body mass index (BMI) for male was above standard. The amount of physical activity of working people has dropped and the resulting poor physical condition is becoming a threat to their working ability, health and well-being. Contemporary life style is connected to full time job that reduces the time dedicated to physical activities. The consequences of physical inactivity are associated to multiple health related problems. Musculoskeletal pathology is one of the most common work–related health problem, as well as an important cause of morbidity for population. It is an inflammatory and degenerative ailment that affects all individuals in working age. The aim of the study is to determine and evaluate the daily physical activities and their general level for the part-time students, give characteristic of anthropometric parameters for part time students.
