Postural control and breathing are mechanically and neuromuscularly interdependent. Both systems- of spinal stability and respiration- involve the diaphragm, transversus abdominis, intercostal muscles, internal oblique muscles and pelvic floor muscles. The aim of the study was to evaluate the effect of exercises activating deep stabilizer muscles on postural control and quality of breathing movements. Eighteen volunteers (25,7 ± 3,5) were recruited from the general population. All the subjects implemented an exercise program activating deep muscles. Head, pelvic and trunk positions in the sagittal and frontal planes were assessed with the photogrammetric method. Breathing movements were estimated with the respiratory inductive plethysmography. The results indicate that the use of deep muscle training contributed to a significant change in the position of the body in the sagittal plane (p = 0.008) and the increase in the amplitude of breathing (p = 0.001).
This study in children aged 6–13 years (n = 1,499) was performed between October 2008 and March 2009. Height and weight measurements were taken to calculate BMI. The prevalence of overweight and obesity was determined by means of IOTF cut-offs with respect to age. Alarming is the fact that the percentage of obese children in Cracow increased dramatically from 1.04% in boys and 0.20% in girls in 1971 to 7% in boys and 3.6% in girls in 2009. In this report, a higher percentage of overweight boys was observed in rural boys (28.14%) than in urban ones (27.31%). Obesity was identified in an almost twice as high percentage of urban boys (7.78%) as in rural ones (3.52%). A higher percentage of overweight girls was registered in rural areas (16.49%) than in urban ones (16.09%). Obesity was prevailing in rural girls (4.12%) relative to their urban counterparts (3.44%). The highest number of overweight urban boys was diagnosed in the group of 12-year-olds (n = 48) and rural boys in the group of 10-year-olds (n = 39), as well as in urban girls aged 11 (n = 17) and rural girls aged 9 (n = 9). The highest number of obesity was observed in rural boys aged 12 (n = 3) and in urban boys aged 9 and 10 (n = 9 in both groups). In the group of girls, obesity prevailed in urban 9-year-olds (n = 5) and in rural 7-year-olds (n = 5). Conclusions: Overweight and obesity affect boys almost twice as frequently as girls. Obesity is twice as frequent in urban boys as in their rural peers.
Purpose To evaluate the extent to which the population of Polish preadolescents is vitamin D deficient and to assess seasonal variations in vitamin D status. Participants and methods A total of 720 healthy children aged 9-13 years (409 girls, 311 boys) residing in 6 representative geographical locations in Poland were studied. A parental-assisted questionnaire provided data on nutritional habits, vitamin D supplements and sun exposure. Serum concentration of 25-hydroxyvitamin was determined twice, after the winter in March and after the summer in October. Results In March, vitamin D deficiency (25-50 nmol/L) was found in 64%, and severe deficiency (< 25 nmol/L) in 20.2% of children. In October, the deficiency and severe deficiency were still noticed in 25.9 and 0.1% of children, respectively. The mean serum concentration of 25-OHD was 52% higher in October (55.4 ± 14.0 nmol/L) than in March (36.4 ± 13.5 nmol/L), (p < 0.01). In children with 25-OHD < 50 nmol/L in March, their 25-OHD concentration increased by 64% through March to October (32.5 ± 8.2 vs. 53.2 ± 7.9 nmol/L, p < 0.01). An association was found between 25-OHD concentration and regular consumption of vitamin D supplements, cod-liver oil and fish. Conclusions The majority of preadolescent Polish boys and girls show vitamin D deficiency after the winter period, although a distinct amelioration over summertime is found in this age group. There is a need to implement effective prevention and intervention strategies in the management of vitamin D deficiency among schoolchildren in Poland, with the supplementation throughout the entire year.
Szczygieł E, Zielonka K, Mętel S, Golec J. Musculo-skeletal and pulmonary effects of sitting position -a systematic review. Ann Agric Environ Med. 2017; 24(1): 8-12. doi: 10.5604/12321966.1227647 Abstract Introduction. Year after year, we spend an increasing amount of time in a sitting position. Often, we sit with poor posture, as indicated by numerous pain syndromes within the musculoskeletal system. Several reports confirm that body posture and the amount of time spent in a seated position have extensive implications for our health. Previous studies and a literature review suggest there is limited knowledge regarding an ergonomic sitting position. Objective. The aim of the study was to analyze the research relating to a proper sitting position and the consequences of incorrect sitting posture. A database search was conducted in Science Direct, Scopus, PubMed, Medline, and Google Scholar. Selection was made on the basis of titles, then abstracts and full texts of the studies. No limits were applied to the date of publication. Conclusions. Incorrect sitting posture contributes to many disorders, especially in the cervical and lumbar spine. It also determines the work of the respiratory system. Most authors suggest that maintenance of the physiological curvature of the spine is crucial for the biomechanics of the sitting position, as well as the location of the head and position of the pelvis. It raises awareness of work-related hazards and the introduction of education on the principles of proper seating. It is necessary to draw attention to the risks associated with work performed in a sitting posture, and education on the principles of ergonomical sitting.
The purpose of our study was to assess if the Polish translation of the European Organisation for Research and Treatment of Cancer (EORTC) Colorectal Cancer (CRC)-Specific Quality of Life Questionnaire (QLQ-CR29) is an acceptable and psychometrically valid measure to collect quality of life (QoL) data in Polish patients with CRC for use in clinical trials and clinical practice. A total of 150 patients undergoing treatment for CRC were prospectively enrolled in the study. Psychometric assessment of the translated QLQ-CR29 structure, reliability, convergent and divergent validity, and clinical validity was subsequently performed. The Cronbach's alpha coefficient ranged from 0.70-0.89, indicating acceptable internal consistency. For test-retest reliability, the ICCs for each item ranged from 0.59-0.91, with exceptions for urinary incontinence and dysuria, indicating good to excellent reproducibility. In multi-trait scaling analyses, the criterion for item convergent and divergent validity was satisfied. The correlations between the EORTC QLQ-CR29 and QLQ-C30 scales were mostly low (r < .40), with a few items demonstrating higher correlations. The known group comparisons analyses demonstrated the ability of the questionnaire to distinguish between patients' differing age, stoma status, and treatment intent. The Polish translation of the QLQ-CR29 is a psychometrically reliable and valid tool. The results of this study are congruent with that of EORTC validation.
The head is an important element of the biokinetic chain. Under physiological conditions, it should extend along the midline of the body. Due to its location and the fact that it constitutes approx. 6% of the total body weight, many authors believe it has a significant impact on its functioning. The aim of this study was to conduct a systematic literature search and to synthesize the evidence of the impact of the head posture on the functioning of the human body. A systematic review was conducted within 3 databases: PubMed, Medline OVID, and EBSCO, using the following terms: "forward head," "posture," "position," and "neck." For the analysis, scientific articles published after 2013 were selected. A total of 16 studies matched the in clusion criteria of this systematic review. Their results have proven that the position of the head has a significant effect on the human body. Research findings show that abnormal head position changes affect muscle activity, proprioception, the pattern of breathing and neck pain. This is the first systematic review of the relationship between the head posture, and the functioning of the human body. The results of this study seem to be promising if used in therapeutic practice.

Introduction: Lipodystrophy is a common problem for modern women. So far, no fully effective therapeutic methods have been developed to eliminate this type of change. Vibration massage is a method that has not yet been studied in the prevention and elimination of lipodystrophy symptoms. Aim of the study: The aim of this study was to evaluate the effectiveness of vibrotherapy on the reduction in lipodystrophic changes. Material and method: 10 volunteers with cellulite changes at the age of 21-23 with physical activity levels described by the international IPAQ questionnaire participated in the study. All women included in the study were evaluated on the basis of 5-day nutrition analysis. Before and after 4 weeks of vibrotherapy, waist, hip and thigh circumferences were measured, and body composition was assessed using bioimpedance and dermatoscope photos were taken. Oscillating cycloidal vibration was generated by the Vitberg+ Rehabilitation Device (Nowy Sącz). Results: After the 4-week series of vibrations, the following average reduction in thigh circumference was observed (Δ1.55 cm, p = 0.002 for right thigh, Δ1.50 cm, p = 0.000 for left), hips (Δ1.25 cm, p = 0.006) and waist (Δ2.30 cm, p = 0.002). The proposed treatment series caused a reduction in body fat mass (Δ0.42 kg, p = 0.009) without affecting the body’s water content, and the analysis of dermatoscopic imaging results revealed improvement in skin perfusion. Conclusion: Oscillating-cycloidal vibration therapy can be an effective tool to alleviate lipodystrophic changes
