This article concerns the problem of assessing selected body compo- sition parameters after completion of antitumor therapy and comparing them with the same parameters of healthy children. A high percentage of overweight and obesity, as well as abnormal fat distribution in convalescents with cancer shows a significant adverse effect of therapy on body composition and suggests the need for early intervention in terms of diet and exercise, which would help patients to quickly achieve the proper parameters of body composition. Two (...) main problems will be mentioned during the presented data analysis. Firstly, in each group there was a small number of observations. Because of this, the real differences between examined subgroups may have been omitted. Secondarily, many variables are correlated and are not normally distributed. Therefore, be- side the standard statistical tests to compare two groups, principal component analysis was applied to reduce the dimensions of the attribute space and to attempt to classify two groups of patients.

This study concerns the problem of late complications of antineo-plastic therapy. Reduced parameters of the cardiorespiratory system in childhood may have a tremendous impact on health. In order to assess the selected parameters, to evaluate physical endurance, and compare the results with those obtained for healthy children, a test was carried out on a treadmill, until 80% of maximum pulse rate was reached. To compare the differences between the treatment group and the control group, three approaches were used. The first (...) one was the classical statistical inference, the second consisted in forming a multidimensional normal model and also involved modelling of the correlation between variables. The unstructured type of the working correlation matrix was chosen to obtain the results and correct standard errors. In the last approach, logistic regression was used to model the relationship between binary outcome and covariates, and to differentiate between the groups of patients on the basis of their cardiovascular parameters.

The aim of this paper is to describe and assess the energetic-metabolic activity of selected muscles of upper and lower extremities during Rotational Training (RT). The influence of RT on temperature changes in the biceps and triceps brachii muscles as well as the quadriceps and biceps femoris muscles of healthy university students were verified, in addition to temperature differences between the left and right side before and after RT. The study was conducted on 18 subjects. RT was conducted in accordance (...) with accepted forms of training methodology of collective fitness. An important part of RT was the performance of circular and rotational movements. Thermograms taken before and immediately after RT focused on 4 regions of selected agonists and synergists in the upper and lower body. The camera used was the infrared hand-held CEDIP Titanium 560M IR (USA), located at a distance of 10 m from the subject. After RT, medianTsk(skin temperature) decreased in almost all of the examined ROIs, except for the left and right Qf (the quadriceps femoris, rectus femoris, and sartorius muscles) as well as the left Tb (triceps brachii) in female subjects. In male subjects, left and rightTskof Qf increased both for the left and right Tb. Left-Right ΔTsk(temperature difference) was statistically significant (p<0.05) for Of, Bf, Bb, Tb in female as well as male subjects. It was concluded that thermography is a non-invasive, safe, and low-cost method for the recording of physiological response of the skin to RT. (shrink)
