People with Down syndrome (DS) show dysfunction of gait, expressed by disturbed character of angular changes and values of the spatiotemporal parameters as compared to the physiological norm. It is known that exercises and various activities have positive effect on balance and gait, but there are only a few scientific proofs concerning above-mentioned in people with DS. Furthermore, the effect of Nordic Walking (NW) training on gait in people with DS is unexplored. We enrolled 22 subjects with DS, aged 25-40 years, with moderate intellectual disability. Participants were randomly divided into 2 groups: NW training group which underwent 10 weeks of training at a frequency of 3 times a week and control group with no specific intervention. Subjects were examined twice: 1 week before training and a week immediately after intervention. Gait was evaluated by the Vicon 250: a computerized system of three-dimensional analysis of motion, connected to 5 infrared video cameras. We conducted mixed-design ANOVA model to assess the effects of time and type of training on spatiotemporal parameters. We found significant favorable time by group interaction in the following parameters: step length in right leg: F(1,15) =14,47, p=0.002; left leg accordingly F(1,15) =5,15, p=0.038, cycle length in right leg: F(1,15) =14,48, p=0.002; left leg accordingly F(1,15) =15,09, p=0.001; and gait standardised speed F(1,15) =5,35, p=0.035. Statistically significant changes were observed in numerous kinematic parameters of ankle, knee, pelvis, and shoulder in NW group. Regular NW training has positive influence on selected spatiotemporal and kinematic parameters in people with Down Syndrome and may be an attractive and safe form of rehabilitation.
The aim of this study was to examine and assess the impact of a series of 20 whole-body cryotherapy (WBC) treatments on the biochemical and rheological indices of blood in people with multiple sclerosis. In this prospective controlled study, the experimental group consisted of 15 women aged 34–55 (mean age, 41.53 ± 6.98 years) with diagnosed multiple sclerosis who underwent a series of whole-body cryotherapy treatments. The first control group consisted of 20 women with diagnosed multiple sclerosis. This group had no intervention in the form of whole-body cryotherapy. The second control group consisted of 15 women aged 30–49 years (mean age, 38.47 ± 6.0 years) without neurological diseases and other chronic diseases who also underwent the whole-body cryotherapy treatment. For the analysis of the blood indices, venous blood was taken twice (first, on the day of initiation of whole-body cryotherapy treatments and, second, after a series of 20 cryotherapy treatments). The blood counts were determined using an ABX MICROS 60 hematological analyzer (USA). The LORCA analyzer (Laser–Optical Rotational Cell Analyzer, RR Mechatronics, the Netherlands) was used to study the aggregation and deformability of erythrocytes. The total protein serum measurement was performed using a Cobas 6000 analyzer, Roche and a Proteinogram-Minicap Sebia analyzer. Fibrinogen determinations were made using a Bio-Ksel, Chrom-7 camera. Statistically significant differences and changes after WBC in the levels of red blood cells (RBC), hemoglobin (HGB), hematocrit (HCT), elongation index, total extend of aggregation (AMP), and proteins (including fibrinogen) were observed. However, there was no significant effect of a series of 20 WBC treatments on changes in blood counts, rheology, and biochemistry in women with multiple sclerosis. Our results show that the use of WBC has a positive effect on the rheological properties of the blood of healthy women.
Introduction. Demographic forecasts indicate the progressive aging process of societies in all countries worldwide. The extension of life span may be accompanied by deterioration of its quality resulting from a decrease in physical activity, mental or even social performance, and a deficit in certain chemical compounds responsible for proper functioning of the body. Aim. The aim of the study was to evaluate the influence of a 12-week Nordic walking (NW) training intervention on the level of vitamin D in the blood and quality of life among women aged 65–74 years. Materials and methods. The study comprised 37 women aged 65–74 (x = 68.08, SD = 4.2). The subjects were randomly assigned to 2 groups: experimental group (NW), which consisted of 20 women who underwent an intervention in the form of Nordic walking training for 12 weeks, and the control group (C), including 17 women who underwent observation. In the experimental group, training sessions were held 3 times a week for 1 h. At that time, the C group was not subject to any intervention. The SF−36 questionnaire was used to measure quality of life. Vitamin D was assessed based on the results of biochemical blood tests. The analysed parameters were assessed twice-before and after the completed intervention or observation. Results. Comparison of the results regarding trials 1 and 2 allowed to note statistically significant improvement in quality of life for all health components and factors in the NW group. Analysis of vitamin D levels demonstrated a statistically significant increase in the NW group. In group C, no significant changes in the analysed parameters were observed. Conclusions. Regularly undertaking Nordic walking training significantly influences the improvement of self-evaluation regarding the components of physical and mental health, as well as the concentration of vitamin D in women aged 65–74 years.
The aim of the study was to compare the effect of a series of 20 whole body cryotherapy (WBC) sessions on iron levels and neuroplasticity biomarkers in women with multiple sclerosis (MS) and healthy women. Consent was obtained from the Bioethics Committee at the Regional Medical Chamber in Krakow (87/KBL/OIL/2018; 8 May 2018). The study was registered in the Australian New Zealand Clinical Trials Registry (ACTRN12620001142921; 2 November 2020). The study included 30 people: 15 women with multiple sclerosis (mean age 41.53 ± 6.98 years) and 15 healthy women (mean age 38.47 ± 6.0 years). Both groups attended cryotherapy sessions. Venous blood was collected for analysis before the WBC session and after 20 sessions. In women with MS and healthy women, no significant effect of WBC on changes in the level biomarkers of neuroplasticity was found. There were also no statistically significant differences between the groups of the analyzed indices at the beginning of the study.
OBJECTIVE: assessment of the effect of a series of 20 whole-body cryotherapy sessions on the morphological and rheological indicators of blood in healthy people. METHODS: The experimental group consisted of 15 women and 15 men who underwent a series of whole-body cryotherapy treatments. The control group consisted of 15 women and 15 men - without intervention. For the analysis of blood biochemical parameters, venous blood was collected twice: Study 1: on the day of the commencement of whole body cryotherapy / from the control group; and Study 2: after a series of 20 cryotherapy sessions / from the control group (4 weeks). RESULTS: After whole-body cryotherapy a statistically significant decrease in RBC, HGB, HCT, MCV, EI 0.30 and an increase in MCHC and EI 2.19–60.30 were observed in women, as well as a decrease in MCV, MCH, AI and an increase in PLT, EI 0.30–60.30, AMP, T1/2 in men. CONCLUSIONS: The use of whole-body cryotherapy causes changes in blood counts in various directions and has a positive effect on the rheological properties of blood in women and men - it increases the elongation index and reduces the aggregation index.
