Introduction The growing research demonstrates that breast cancer surgery and adjuvant radiation therapy greatly improve the long-term results of cancer treatment, overall survival, but leads to negative side-effects including from the respiratory system and quality of life. Aim: To evaluate the impact of a 12-week water program on the respiratory function in breast cancer survivors. Material and methods 68 patients who had survived breast cancer participated in a 12-week physical rehabilitation. Pulmonary function parameters were evaluated in 34 women who performed water program (group A) and 34 women who received Pilates program (group B). Participants of both groups attended 36 rehabilitation sessions over 3 months. Results Based on the results of 12-week rehabilitation, it has been determined that proposed water program is more effective for improvement of pulmonary function in breast cancer survivors at outpatient rehabilitation. It was demonstrated that vital capacity and forced vital capacity were statistically higher by 270 (p<0.001) and 190 ml (p<0.01), respectively in women of group A as compared to the group B. The respiratory minute volume was lower in group A by 1.06 l/min (p>0.05) compared to the group B that indicated about more economical ventilation in rest and increasing the functional reserve of the respiratory system in breast cancer survivors. Conclusions The water-based program appears to be more effective then a Pilates program for improvements in vital capacity, forced vital capacity, maximal voluntary ventilation, and expiratory reserve volume in breast cancer survivors.
Introduction Surgical treatment and radiotherapy can prolong the life expectancy of women with breast cancer but also might have side effects on heart rate variability. Currently breast cancer treatment has contributed to significant improvements in survival rate, but negative effects on the psycho-emotional state and functionality of the autonomic nervous system of these interventions in women is high. We aimed to investigate the heart rate variability features in breast cancer survivors who have varied attitudes towards the disease. Material and methods Heart rate variability analysis, determination of various attitudes towards the disease, and mathematical statistical methods. The survey of 110 breast cancer survivors was conducted utilizing Type of Attitude Toward The Disease questionnaire. The women were executed radical mastectomy and adjuvant radiation treatment for breast cancer. Patients aged between 56 and 60 years. Results The results of our study showed that patients with a rational type of attitude towards disease had statistically (p<0.05) better parameters of heart rate variability. Values of standard deviation of the N-N interval, root mean square of successive differences, total power, high-frequency range, and stress index were much better in patients with rational type of attitude as compared with the women who had intrapsychic and interpsychic attitudes. Conclusions These data show that identified features of various attitudes towards the disease in breast cancer survivors clarify the necessity for particular attention to their heart rate variability parameters.
Introduction The aim of this study was to examine the effect of yoga on heart rate variability in patients with breast cancer in an outpatient rehabilitation program. Material and methods Eighty-four patients with breast cancer were eligible for this study. After the exclusion of 7 women, 77 participants were randomly allocated to a yoga exercise program (group A, n=33) and Pilates exercise program (group B, n=44). Heart rate variability parameters were evaluated at baseline, after six and twelve months of yoga exercises. Results After twelve months of performing yoga exercises, standard deviation of the normal-to-normal intervals (SDNN) improved by 5.53 ms (p<0.001), square root of the mean of the squared differences between adjacent normal RR interval (RMSSD) improved by 4.91 ms (p<0.01), total power (TP) improved by 279.78 ms2 (p<0.001), very low frequency (VLF) improved by 109.76 ms2 (p<0.01), low frequency (LF) improved by 88.38 ms2 (p<0.01), high frequency (HF) improved by 77.60 ms2 (p<0.05), and stress index (Si) improved by 137.24 c.u. (p<0.01). Based on the results after 12 months, women in group A showed significantly better results compared to group B in SDNN by 3.28 ms (p<0.05), RMSSD by 3.34 ms (p<0.05), TP by 170.33 ms2 (p<0.05), HF by 64.33 (p<0.05), and Si by 56.49 c.u. (p<0.05). Conclusions Performing the yoga exercise program resulted in an increase of the parasympathetic and baroreflex effects on the cardiovascular system and a decrease in the tonic effects of the sympathetic nervous system. Yoga should be considered as an effective tool in normalizing the functional state of the autonomic nervous system.
Introduction The aim of the study was to analyze the changes in the indices of the autonomic nervous system and the adaptive capacity of Ukrainian Super League handball players prior to significant competitions. Material and methods This research involved 39 handball players from the Ukrainian Super League aged 18–22 years old. The study examined the overall tone of the autonomic nervous system (ANS ) measuring electrodermal activity of the athletes. Reactivity of the ANS of players was monitored by the method of R. Baevskyy, the efficiency of competitive activity in handball was analyzed by the integral index of technical and tactical handball skills. Results Before the competition, the reaction in the sympathoadrenal system was launched for vagotonics as the intended response to the upcoming games. The measured indicators marked mental stress and activation of the sympathoadrenal system for the sympathotonics group. The аtonics group provided the emotional ground due to the balanced influence of para- and sympathetic divisions of the autonomic nervous system. Conclusions The index of functional changes in all participants detected a satisfactory level of adaptation. The highest sympathetic activity was observed for аtonics, the lowest – for vagotonics. The best results were documented for athletes who did not have autonomic dysfunction and those who had a slight predominance of the sympathetic component of the autonomic regulation.
