Abstract
Introduction. Copper and iron are necessary elements in the process of creating red blood cells. Copper activates the enzyme catalyzing bond between an iron and a ligand of a porphyrin. Iron participates in the last stage of blood biosynthesis. A deficit of one of these bioelements causes perturbations in the hemoplastic system. Material and methods. Solidification of the elements iron and copper was studied in the hair of school-age children (10-12 years old). The mineral composition of the human organism was analyzed by applying the method of atomic absorption spectrophotometry (AAnalyst 800 Perkin-Elmer Company) using flame atomizer and one-element hollow cathode lamp. Similarities and differences between results we obtained and the results reported by other scientific centers were examined. Results. Medium copper concentration in the tested hair was 8.43 mg/g and the iron concentration was 10.15 mg/g. The level of these two elements was lower compared to the results reported by other researchers. The copper contents in the hair of girls and boys was 8.21mg/g and 8.63mg/g respectively, and iron content was 9.7mg/g and 10.68mg/g respectively.Conclusion. Our results show that the Cu and Fe concentration in the hair of children from Bydgoszcz is lower when compared to data received from other regions of Poland. New research is needed to determine if this results from dietary deficits, and if so, to develop solutions.

Jacek Klawe, Małgorzata Tafil-Klawe, Katarzyna Dmitruk, Wojciech Sikorski, Maciej Śmietanowski – Does reduction of body mass diminish the risk of arterial hypertension in obese persons working at night? Fizjoterapia Polska 2003; 3(1); 62-65

Abstract
Introduction. An increase in arterial blood pressure is observed in healthy subjects after sleep deprivation. Our previous studies indicated that this reaction is augmented in obese subjects, suggesting a greater possibility of arterial hypertension after night-shift work in obesity. The question arises, does the reduction of body mass prevent the increase in arterial blood pressure after sleep deprivation? Material and methods. The investigation was performed in 6 male obese subjects before and after body mass reduction to normal levels. 24 h blood pressure monitoring was performed after night- shift work in an isolation chamber where temperature and humidity were kept constant. Results. The values of mean arterial pressure in obese subjects in the 24 h period after night work were significantly higher as compared with the values observed after night work, after body mass reduction (P < 0.05). Discussion. Our results demonstrate that in obese subjects night work may be a potential arterial hypertension risk factor, and body mass reduction may prevent development of arterial hypertension.

Abstract

Background. Process of maintaing balance during upright stance is a very specific motor activity which requires correct co-operation of 3 components equilibrium system: visul, vestibular and proprioceptive. One of the objective method assessment of body stability is posturography (recordings of centre of foot pressure – COFP). The goal of the present study was to evaluate body stability of children dancers. Material and methods. Our research involved 30 children dancers divided into 2 groups: 9-12-year old and 13-16-year-old. Children no-dancers was the control group.Results. The posturography examinations provided us the less values of parameters for dancers as compared with control group, besides parameter – co-ordination which was higher. Conclusions. Obtained results indicate better body stability and visual motor co-ordination of children dancers. The results from this work support a differences between children dancers and no-dancers in their postural control.

Andrzej Lewandowski, Martyna Wasielewska, Ryszard Grucza, Jacek Klawe, Paweł Zalewski – Selected types of work load of male physiotherapists in hospital setting. Fizjoterapia Polska 2010; 10(3); 234-241

Abstract
Background. Physical effort is part and parcel of the work of physiotherapists. The profession is generally associated with relatively strenuous physical work. Men and women perceive the level of physical load similarly. The present work aims to assess exercise loads associated with selected activities performed by physiotherapists working in the hospital setting.Material and methods. Three widely utilised standard therapeutic procedures were selected, namely: passive exercises, individual resistance exercises, and verticalisation and gait education. The study involved young men employed in hospital departments of rehabilitation and neurology. Their physical capacity was measured with the PWC170 exertion test; the intensity of physical effort was assessed indirectly by measuring the heart rate.Results. The male physiotherapists had low physical capacity (3.8 l/min ± σ = 0.63). The intensity of physical effort during the selected standard procedures was low, mean heart rate was HR 106.82 ± σ = 15.41, and maximal oxygen uptake was VO2max=56.60%. Nevertheless, physiotherapists subjectively perceived their duties as strenuous. The results of the present study showed that their work can be classified as strenuous, but only when the principles of hygiene and ergonomics are taken into consideration.Conclusions. Conclusions are drawn regarding the need to keep physiotherapists’ physical capacity at an appropriate level and to establish contraindications to perform standard therapeutic procedures associated with considerable physical effort.
