Purpose. Physical activity is an integral part of the treatment of diabetes. The aim of the study was to assess aerobic capacity and cardiovascular-respiratory reactions to a single physical exercise with gradually increasing intensity in normobaric hypoxia in patients with Type 1 diabetes. Methods. The study was conducted on a sample of adults with Type 1 diabetes (GT1D, n = 13) and a randomly chosen healthy control (GK, n = 15). The study participants performed a progressive exercise test to exhaustion in normoxia (FiO2 ~ 20.90%) and 7 days later in normobaric hypoxia (FiO2 ~ 15.14%). At rest, during exercise, and after completion of the test blood was drawn and physiological indicators were monitored. Results. Two-way ANOVA revealed a significant effect of hypoxia and physical exercise on blood glucose concentrations (F = 6.1 p < 0.01). In GT1D , lower glucose levels were observed in normobaric hypoxia compared with baseline and post-exercise levels in normoxia (p < 0.05). A tendency to increased maximal oxygen uptake and significantly higher minute pulmonary ventilation was observed in both groups in response to exercise and hypoxia. Conclusions. Physical activity and hypoxia may effectively control glucose homeostasis and increase cardiorespiratory adaptation to exercise in Type 1 diabetics.

Introduction: The effort test is the most popular type of a test used for the verification of a heart disease. The main target of rehabilitation is to achieve the improvement of exercise tolerance. Material and methods: The examination group included 60 patients aged 34-76 (average 60±8,87) qualified for II period of rehabilitation. The effort test on a movable track has been carried out before and after the rehabilitation, according to the modified Bruce’s protocol. The following parameters were tested: a heart rate rest and maximum, blood pressure rest and maximum, test duration, costs of energy effort (METs), a reason for test interruption, subjective sense of tiredness, a number of breaths per minute and a maximum intake of oxygen (VO2max). For the A model, 14 patients have been qualified, B-31, C-15, D-0. In that case, the training on a cycloergometer was of a continuous type, while for the patients qualified for the B and C models, was of an interval type. Results and conclusions: The biggest part of work was done during the final 21st training. The increase in exercise tolerance was proven, due to the obtained results.

Introduction: Assessment of exercise tolerance (ET) plays an important role in qualifications for treatment and rehabilitation. Aim: The aim of the study was to assess ET in patients before and after inguinal hernia operations with Lichtenstein method. Material and methods: The cohort study included men with inguinal hernia divided into the study group (SG) (n = 50) and control (CG) (n = 50) undergone the Lichtenstein surgery. Patients from the SG met the criterion of coexistence of cardiovascular and respiratory diseases. Day before and on the second day after surgery, patients performed 6MWT and subjectively rate the exertion according to Borg- RPE- Scale (before, immediately after and 10 minutes after the test). 6MWT distance, Borg scale ratings were analysed. On the second day after surgery 66% of patients from the SG and 58% from the CG did not complete the test. Patients from the SG before (500,07 ± 40,38 m) and on the second day after surgery (243,46 ± 18,18 m) achieved shorter distances compared to the CG (565,93 ± 20,41 m; 249,47 ± 26,66 m), p < 0,001 i p = 0,481. A statistically significant negative correlation between 6MWT distance before surgery and age of the patients was confirmed. Patients who did not develop complications achieved significantly longer distances on admission (p = 0,003 for SG, p = 0,004 for CG). For 6MWT before surgery and 2 days after surgery, patients from the SG showed a significantly higher level of fatigue compared to the CG after the test (before: p = 0,001, after: p = 0,001). Patients form the SG often discontinued 6MWT and less tolerated effort compared to the CG. Hence, 6MWT is useful tool for ascertaining physical capacity and ET.
