Regular training modulates airway inflammation and modifies susceptibility to respiratory infections. The impact of exercise and ambient conditions on airway hyperreactivity and innate immunity has not been well studied. We aimed to assess exercise-related symptoms, lung function, airway hyperresponsiveness and innate immunity proteins in relation to meteorological conditions and exercise load in competitive athletes. ⋯ Ambient training conditions, but not training load, influence bronchial hyperreactivity and the innate immune response in competitive athletes assessed during winter. The protective effect of regular exercise against respiratory infections is associated with a shift in serum innate immunity proteins.

Oxidative stress has been implicated in the normal ageing process and the pathogenesis of several diseases, including goitre. The aim of the study was to evaluate the relationship between urine lipid peroxidation (LPO) and anthropometric parameters as well as the parameters associated with goitre formation in children. ⋯ Anthropometric parameters of school-age children independently of age are negatively associated with oxidative damage to membrane lipids, whereas factors promoting goitrogenesis do not contribute to this process.

The validity of self-reported vs. measured body weight and height and the effect of self-perception.
The objective was to assess the validity of self-reported body weight and height and the possible influence of self-perception of body mass index (BMI) status on the actual BMI during the adolescent period. ⋯ The results of this study demonstrated that in determining obesity and overweight statuses, non-accurate weight perception is a potential risk for students.

One reason for the limited effectiveness of the available smoking cessation methods is the fact that the causes of tobacco addiction have not been adequately explained yet. Numerous anti-smoking programs aimed at women involve intense physical activity. The goal of the study was to evaluate the effectiveness of health training for smoking cessation by young women in connection with the dopamine receptor gene (D4DR) in their genetic profile. ⋯ The results of the study show that an intensive, 6-week health training program had a significant influence on smoking cessation. Smoking quitters, who are genetically predisposed and decide to take up aerobic training in combination with concentration training, have much greater chances of quitting smoking.

Apart from many positive changes associated with technical civilization, there are also - from the health point of view - some threats. The reduction in the level of physical activity is one of them. The aim of the study was to investigate whether there are any relationships between children's physical activity and behaviors, and to assess the impact of the adults' activity on their children's habits. ⋯ The level of physical activity in younger children depends on the children's relationship with their parents and their level of activity. Children spend a lot of free time with their electronic devices. It is necessary to develop and implement activities intended to raise awareness of children and their families about the effects of hypokinesis.
