Epidemiology of physical activity in adult Polish population in the second decade of the 21st century. Results of the NATPOL 2011 study

Objectives: The aim of the study was to assess physical activity (PA) level in a representative sample of Polish adults.Materials and Methods: A cross-sectional analysis was performed among 2413 randomly selected individuals (51.5% women) aged 18-79 years, who participated in the Nationwide Study of Occurrence of Risk Factors of Cardiovascular Diseases NATPOL 2011 (March-July 2011). The study procedures consisted of a questionnaire as well as of anthropometric, blood pressure and biochemical measurements. Leisure-time, occupational and commuting PA were assessed by the use of a questionnaire interview. Results: About 48.2% of adults do exercise for at least 30 minutes on most days of a week. About 11% of the respondents declare a sedentary lifestyle. About 26.5% of working population report hard physical work, while sedentary work is reported by 47.6% of the employed participants. Active commuting is declared by 27.3% of working/studying population. About 47.2%, 36.6%, and 15.3% spend 30 min per day, respectively, on this kind of PA. Conclusions: PA level of more than half of Polish adults is still not satisfactory. Promotion of an active lifestyle should concern mainly leisure-time and commuting PA with paying special attention to substantial differences in various socio-demographic groups

Effect of Nordic Walking training on iron metabolism in elderly women.

BACKGROUND: Despite several, well-documented pro-healthy effects of regular physical training, its influence on body iron stores in elderly people remains unknown. At the same time, body iron accumulation is associated with high risk of different morbidities. PURPOSE: We hypothesized that Nordic Walking training would result in pro-healthy changes in an elderly group of subjects by reducing body iron stores via shifts in iron metabolism-regulating proteins. METHODS: Thirty-seven women aged 67.7±5.3 years participated in this study. They underwent 32 weeks of training, 1-hour sessions three times a week, between October 2012 and May 2013. Fitness level, blood morphology, CRP, vitamin D, ferritin, hepcidin, and soluble Hjv were assessed before and after the training. RESULTS: The training program caused a significant decrease in ferritin, which serves as a good marker of body iron stores. Simultaneously, the physical cardiorespiratory fitness had improved. Furthermore, blood hepcidin was positively correlated with the ferritin concentration after the training. The concentration of blood CRP dropped, but the change was nonsignificant. The applied training resulted in a blood Hjv increase, which was inversely correlated with the vitamin D concentration. CONCLUSION: Overall the Nordic Walking training applied in elderly people significantly reduced blood ferritin concentration, which explains the observed decrease in body iron stores

The influence of a form of physical activity nordic walking on the life's quality of people in the 60-70 years age bracket.

The aim of the presented study is to examine the influence of systematic nordic walking training on the subjective quality of seniors' lives. The control group consisted of people who do not take part in any physical activity. In order to reveal the connections between quality of life and participation in nordic walking the examination consisting of three psychological tests was performed. These were the tests measuring the level of satisfaction with life (SWLS), the level of optimism (LOT-R) and the Beck Depression Inventory level. The results of the studies have confirmed the hypothesis that the quality of life in a group of seniors in the experimental group is higher than in the control group. Statistical tests have shown that active seniors feel greater satisfaction from their lives and look in the future more optimistic than their peers in the control group containing inactive seniors. In the experimental group were lower results in scale measuring level of depression. Low results show that systematic training is unconductive to depression development

Balance control contributors - The relationships between leg strength and balance control ability in seniors

The paper presents a study on leg strength as a balance control ability contributor. 9 seniors with the average age of 69.8 years participated in the experimental study. A psychomotor efficiency timer and a standard stabilograph were used in the study. The timer consisted of a computer, a controller and an arm and leg strength measurement station. The subjects performed stepping up movements with the left and right leg in response to two audio-visual signals. The strength of legs was measured indirectly by the time of straightening the first leg put on the step-box. The balance control ability was tested on the basis of the length of the line of center pressure oscillations in the standing position on a force platform. The relationships between the tested factors were examined on the basis of Pearson's correlation. We have found a strong correlation between the balance control ability and the left (0.77) and the right (0.83) leg relative strength and correlation between the strength of the left and the right leg (0.95). Our study has shown that relative leg strength may be treated as a contributor to postural balance control ability

Рухові якості та функціональні характеристики студенток різних типів конституції

He purpose of the article is to study correlation of motor and functional characteristics of students of different somatotypes. Material : it was examined first year students (n=577, 17-18 years old). All students were trained in discipline “Physical education”. It was carried out somatotyping. It was considered motor skills and functional characteristics of students. Results : it was determined the reliable differences in values of parameters of motor tests and functional characteristics of students’ organism. It is determined that by the end of the first year of study the positive dynamics is registered: in sthenics (in two of seven motor tests); in asthenics (in four tests). It wasn’t found the reliable positive changes in group of hypersthenics. Students of sthenic and asthenic somatotypes have higher functional reserves of cardiorespiratory system, than girls of hypersthenics somatotype. Conclusions: constitutional features of motor skills and functional parameters of students of different somatotypes allow to concretize provisions of methodology of planning the individual differentiated training in discipline Physical education.Цель - изучить взаимосвязь двигательных и функциональных характеристик организма студенток различных типов конституции. Материал: обследовано студентки первого курса (n=577, возраст 17-18 лет). Все студентки проходили обучение по дисциплине Физическая культура. Проведено соматитипирование, рассмотрены двигательные качества и функциональные характеристики студенток. Результаты: установлены достоверные отличия в значениях показателей двигательных тестов и функциональных характеристик организма студенток. Установлено, что к концу обучения на 1 курсе регистрируется положительная динамика: у нормостеников (в двух из семи двигательных тестов); у астеников (в четырех тестах). В группе гиперстеников достоверных положительных изменений не отмечается. У студенток нормостенического и астенического типов конституции функциональные резервы кардиореспираторной системы выше, чем у девушек гиперстенического телосложения. Выводы: конституциональные особенности двигательных качеств и функциональных показателей студенток разных соматотипов позволяют конкретизировать положения методологии планирования индивидуально-дифференцированного обучения по дисциплине Физическая культура.Мета: вивчити взаємозв'язок рухових і функціональних характеристик організму студенток різних типів конституції.

Methodology of physical recreation: problems, experience, recommendations

The article contains methodical approaches in the process of conducting practical classes with the students on discipline «Physical recreation». The methodical reception is shown, also their definition, the importance of definitions during the life of the person, including the student. The essence of physical recreation in the understanding of students for passive and active recreation is uncover, as well as formulating the tasks in forming, recovering, strengthening and preserving the health of different age groups of the population. The methodological principles of physical recreation described in detail in the context of its performance by students. It uses traditional principal means for physical culture ((physical exercise, movement modes, natural factors, massage, occupational therapy, mechanotherapy). They are distinguished by various forms, methods, and activities, bearing recreational character
