The Influence of Skin Parameters and Body Composition on the Tolerance of Pain Stimulus Generated During Electrical Muscle Stimulation (EMS) in Women - Pilot Study.

Purpose: This pilot study aims to explore how skin parameters and body composition impact the tolerance to EMS (Electrical Muscle Stimulation) stimuli in women, particularly focusing on pain tolerance in response to varying intensities of EMS. This research seeks to understand what is essential for optimizing EMS applications. Patients and Methods: The study involved 16 females (age 35.9 ± 12.3). Body composition and anthropometric measurements were taken, including BMI (Body Mass Index), weight percentage, WHtR (Waist to Height Ratio), WHR (Waist-Hip Ratio), and Bioelectrical Impedance Analysis. High-frequency ultrasound scans were conducted to assess skin parameters. The EMS stimulation was performed using an Evolvex (InMode, Israel), with applicators placed around the abdomen and intensity adjusted according to patient tolerance, recorded at the pain threshold. Results: The maximum tolerated EMS stimulus varied from 12V to 55V, with a median of 33V. Body weight showed a strong positive correlation (R=0.76, p<0.001) and hip circumference (R=0.66, p<0.001) with EMS intensity. Body fat mass (R=0.61, p=0.012) and visceral fat area (R=0.55, p=0.029) were positively correlated with EMS intensity. However, no significant correlations were observed between EMS tolerance and muscle tissue parameters or total body water content. The study also found that skin structure parameters showed no significant impact on EMS tolerance. Conclusion: The study reveals that women's tolerance to EMS stimuli is influenced by various factors. Anthropometric parameters like hip circumference, body weight, skinfold, and BMI are strongly correlated with EMS tolerance. Body composition factors, particularly adipose tissue characteristics such as body fat mass and percentage, also significantly impact EMS intensity requirements, with no notable correlation to muscle tissue or water content. However, variations in skin structure, including thickness and density, do not significantly affect EMS tolerance. These insights are crucial for tailoring personalized EMS therapy to enhance effectiveness and comfort in both aesthetic and rehabilitative applications.

Changes in sensitivity and hedonic rating to transcutaneous electrical nerve stimulation following COVID-19.

COVID-19 affects not only the respiratory system but also other biological systems such as the nervous system. Usually, these changes are reported based on the patient's subjective description. The aim of our study, therefore, was to objectively determine the effect that the SARS-CoV-2 virus and COVID-19 disease has on sensory threshold and the hedonic and subjective perception of an electrical stimulus. The sensory threshold was tested on the inner forearm by applying non-invasive transcutaneous electrical nerve stimulation (TENS) with 100 Hz and 100 µs parameters and a biphasic current waveform. The study involved 211 participants, aged 22-79 years, with a mean age of 56.9 ± 12.1 years. There were 131 subjects in the COVID group, while the NON-COVID group, the control group, was matched to the COVID group in terms of gender, age, body mass index and presence of chronic diseases. The research was carried out in 2022. Sensory sensitivity was highest in the group that had suffered with COVID-19. The median sensory sensitivity was 11 mA in the COVID group and 14 mA (p < 0.001) in the NON-COVID group, however, the current sensitivity threshold decreased over time (R = 0.52, p < 0.001). Post COVID-19, the electrical stimulus was more often perceived as unpleasant: COVID versus NON-COVID (23% vs. 3%, p < 0.001) and as a different sensation to tingling (27% vs. 2%, p < 0.001). Post-COVID-19 patients have a lower sensory threshold, the electrical stimulus is more often described as unpleasant and in subjective feelings it is more often described as pinching. The differences between COVID and NON-COVID decrease with time since the onset of COVID symptoms.

Psychosocial functioning of women suffering from stress and mixed form of urinary incontinence depending on the severity of the symptoms.

INTRODUCTION: Urinary incontinence is a troublesome symptom that negatively affects many aspects of life among woman suffering from this disease. It disturbs social, professional and intimate relations, and thus contributes to a negative self-image, loss of self-confidence, withdrawal of a woman from social and family life, and consequently promotes negative state of mind and depression. AIM: The aim of the study was to analyse the influence of urinary incontinence on the psychosocial functioning of women suffering from this disease. MATERIAL AND METHODS: The study included a group of 202 women aged 40.1 ± 13.9 years. A proprietary questionnaire was used, aimed at all women who had an episode of urinary incontinence at any time in their life. RESULTS: The impact and perception of the urinary incontinence symptoms depended on its form and severity. Comparing stress urinary incontinence with the mixed form, a greater severity of symptoms in women with the mixed form were observed, respectively 13.6% vs. 53.9%. Taking into account the aspects of life affected by urinary incontinence, it was found that the greatest impact UI had on the social (52.5%), then on the professional (28.7%), and the least impact on the family aspect of life (21.8%). CONCLUSIONS: Research has shown that urinary incontinence has the greatest impact on the social aspect of the surveyed women's life. The reported impact largely depended on the form and severity of urinary incontinence. In over 40% of women, symptoms related to urinary incontinence caused a deterioration of wellbeing and body acceptance. The mixed form was by far the most problematic and had the greatest impact on the daily functioning of women compared to, for example, the stress form.

Who Likes Unhealthy Food with a Strong Flavour? Influence of Sex, Age, Body Mass Index, Smoking and Olfactory Efficiency on Junk Food Preferences.

Background. Unhealthy food is an important element in the development of diseases of civilisation. The aim of this study was to determine how sex, age, body mass index, smoking and olfactory efficiency influence the consumption of such foods. Methods. A total of 283 people living in the Silesian Voivodeship in Poland took part in the study. They were aged 18−82. An interview and olfactory tests were conducted together with assessments of food preferences from 25 types of food products. The extent to which sex, age, body mass index, tobacco addiction and sense of smell influence unhealthy food consumption was assessed. Results. Using the VARIMAX factor analysis, a coherent group of 'unhealthy food with a strong flavour' products was selected: crisps, salty snacks, fast food, sugary carbonated drinks and sour products. Unhealthy food was liked more by people who were younger (B = −0.04; PU = −0.05, −0.03; t = −7.43, eta2 = 0.17; p < 0.001) and who had a higher BMI (B = 0.03; PU ≤ 0.01, 0.06; t = 1.92, eta2 = 0.01; p = 0.056). The efficiency of the sense of smell does not play a significant role in the preference for the 'unhealthy food' group as a whole. The analysis of each type of unhealthy food separately showed that young people liked crisps, salty snacks, fast food and sugary carbonated drinks more, men liked fast food and sugary carbonated drinks more than women, and people with a good sense of smell liked sour products. Conclusion. According to the food preferences stated, dietary education should be targeted at young people, especially young men, to prevent the development of overweight and obesity.

Taste perception and food preferences in patients with diabetic foot ulcers before and after hyperbaric oxygen therapy.

OBJECTIVE: The aim of the study was to evaluate the effect of hyperbaric oxygen therapy (HBOT) on taste perception and food preferences in patients with diabetic foot ulcers. METHODS: The study involved 75 healthy people (Group C) and 23 patients with diabetic foot ulcers before HBOT (Group Db) and after 25-30 HBOT treatments (Group Da) (2.5 ATA, 87 min). The sip and spit method was used to examine the taste perception for 5 basic flavours. Food preferences were studied using photographs of dishes. RESULTS: The recognition thresholds in Group C were lower than in Group Db for 5 basic flavours. The taste intensity in Group C was higher than in Group Db for: 0.1% and 1.0% monosodium glutamate, 0.02% citric acid, and 0.002% quinine hydrochloride. The hedonic response in Group C was more negative than in Group Db for: 0.18% sodium chloride, 0.3% monosodium glutamate and 0.1% citric acid. The pleasure derived from eating in Group C was lower than in Group Db for sour and salty products. The recognition thresholds in Group Db were higher than in Group Da for umami and sour. The taste intensity in Group Db was lower than in Group Da for: 0.1%, 0.3% and 1.0% monosodium glutamate. The pleasure derived from eating in Group Db was higher than in Group Da for chocolate and crisps. CONCLUSIONS: In people with diabetic foot ulcers, an impaired all 5 basic tastes occurred with different food preferences compared to healthy people. HBOT causes beneficial changes resulting in increased sensitivity to umami and sour taste as well as a decrease in the pleasure derived from eating chocolate and crisps.

The Use of Hemispherical Directional Reflectance to Evaluate the Interaction of Food Products with Radiation in the Solar Spectrum.

Food product packaging should block light to protect nutrients, color and active ingredients in functional food from degradation. Currently, packages are not optimized in terms of the solar radiation impact on the products they contain. The aim of this study was to develop a method of quantifying the interaction of food products with solar radiation, which would enable the optimization and selection of packaging that would protect the product from the spectral range specifically absorbed by it. In order to determine the reflectance of chocolate, the total reflectance ratio was measured. For this purpose, a SOC 410 Solar DHR reflectometer from Surface Optics Corporation, San Diego, CA, USA was used. Directional reflectance was measured for seven discrete spectral ranges from 335 to 2500 nm, which correspond to the spectrum of solar radiation. The value of total reflectance for chocolate differed significantly in the studied spectral ranges. The highest reflectance ratio, averaged for all the tested chocolate, was recorded for the spectral range 700-1100 nm and the lowest for the 335-380 nm range. The total reflectance was significantly correlated with the cocoa content and the brightness of the chocolate. The proposed method of hemispheric directional reflectance enables the measurement of the total reflectance of food products. It can be used as a measure of exposure to radiation. Thus, it is possible to design a package that will protect the product from the spectral range that is most harmful for it.

Individual characteristics, including olfactory efficiency, age, body mass index, smoking and the sex hormones status, and food preferences of women in Poland.

Background: Food choices made by most people mainly depend on food preferences. Knowing how certain factors affect food preferences can help dietitians working with women to understand the relationship between individual factors and the challenges faced by the women in changing eating habits. The aim of the study was to examine the food preferences of women and to assess the impact of the sense of smell, age, body mass index (BMI), smoking and hormonal status (phase of the menstrual cycle, hormonal contraception) on the declared pleasure derived from eating various types of food. Methods: A total of 190 women living in the Górnoslasko-Zaglebiowska Metropolis in Poland aged 18-75 (19.29-26.71 RNO) years participated in the study. The collected survey data included age, BMI, smoking, phase of the menstrual cycle and hormonal contraception. Olfactory sensitivity was measured by T08 olfactometer. Additionally, food preferences were assessed, using 24 different food types, which were presented as pictures. To evaluate food preferences 10 cm visual analogue scale was used. Results: The most liked foods were: fruits (M = 8.81, SD = 1.67), sweet desserts (M = 8.44, SD = 2.30), vegetables and salads (M = 8.08, SD = 2.24), chocolate (M = 7.84, SD = 2.76), and poultry (M = 7.30, SD = 2.47). The least liked foods were: salty products (M = 4.98, SD = 3.03), milk soup (M = 3.30, SD = 3.13), and seafood (M = 2.99, SD = 3.28). The influence of the analyzed factors on the degree of liking six food types was shown. Women with better ability to name scents preferred sausages/ham and beef/pork. Women with a higher BMI had lower preference for jellybeans and broth. Women who were heavier smokers had lower preference for milk soup. In women using hormonal contraception, pleasure from eating sausages and ham was higher than compared to women in all phases of the monthly cycle. In women in the follicular phase the pleasure from eating pasta was lower when compared to women in the ovulatory phase, the luteal phase and those using hormonal contraception. In women in the ovulatory phase the pleasure from eating candies and jellybeans was lower when compared to women in the follicular phase, the luteal phase and those using hormonal contraception. In women in the ovulatory phase, also pleasure from eating broth was lower when compared to women in the luteal phase and those using hormonal contraception. Conclusions: Among women in Poland, the top five preferred food types are fruits, sweet desserts, vegetables/salads, chocolate and poultry. To confirm the extent to which the declared pleasure derived from eating these food types translates into health condition, further research on the consumption of these food types is necessary. The impact of the sense of smell, BMI, smoking, or menstrual cycle phase and hormonal contraception on the declared pleasure derived from eating was observed for six out of twenty-four food types. The hormonal status was the factor most significantly influencing food preferences.

An assessment of sensory sensitivity in women suffering from depression using transcutaneous electrical nerve stimulation.

Background: Perception is the process or result of the process arising from the mental interpretation of the phenomena occurring, therefore it depends not only on physiology, but is also psychologically and socially conditioned. The aim of this study was to assess if there is a difference in the sensory sensitivity to an electrical stimulus in women suffering from depression and what the hedonic rating is of the lived experience of transcutaneous electrical nerve stimulation. Methods: The depression group: 44 women, who were inpatients treated for depression at the Psychiatric Ward in the Clinical Hospital, and the control group: 41 women, matched by the age, height and weight, with no mental illness. Measures: threshold for sensing current, type of sensation evoked, hedonic rating. Results: Median sensing threshold of electric current (depression vs. control: 7.75 mA vs. 8.35 mA; no significant), type of sensation evoked (depression vs. control: tingling 90.9% vs. 92.7%, no significant), hedonic rating (depression vs. control: unpleasant 11.4% vs. 2.4%; p = 0.003), hedonic rating (mildly ill vs. moderately ill vs. markedly ill: unpleasant 5.3% vs. 6.3% vs. 33.3%; p = 0.066). Conclusions: Women suffering from depression exhibit a similar threshold of sensitivity to an electrical stimulus as mentally healthy women, however the hedonic rating of the stimulus acting on the skin in the group of clinically depressed women was more negative than in the mentally healthy subjects. The stimulus was described as 'unpleasant' for many of the mentally unhealthy women. The most negative sensations related to the electrical stimulus were experienced by women with the highest severity of mental illness according to The Clinical Global Impression - Severity Scale.

The Female Athlete Triad-the impact of running and type of diet on the regularity of the menstrual cycle assessed for recreational runners.

Background: The Female Athlete Triad (FAT) included three interrelated conditions including disordered eating, amenorrhea, and osteoporosis. The American College of Sports Medicine updated the definition of FAT to reflect the interdependence of low energy availability with or without eating disorders. The main aim of the study was to assess the impact of recreational running on potential disturbances in the regularity of women's menstrual cycles. Additionally, this work compared differences in the menstrual cycle between women runners and women who did not regularly practice sports. The respondents were also asked about the type of diet they consumed. Methods: A total of 360 women took part in the research. This group included 217 runners and 143 control. The authors' questionnaire was used in the research. Results: When compared to the control group, the runners had an increased frequency of menstrual cycles of <24 days (10.14% vs. 3.50%), fewer typical cycles of 25-31 days (75.58% vs. 86.71%), had fewer regular cycles per year (9.62 vs. 11.22), shorter duration of bleeding (4.79 vs. 5.27 days), and an increased frequency of painless menstruation (23.96% vs. 7.69%). A positive predictor of menstrual cycle disorders was the use of a 'special diet' (R:1.67; 95% C:0.47-2.87). Conclusions: The runners had shorter and less regular monthly cycles and shorter and more often painless menstrual bleeding when compared to the control group. The frequency of menstrual disorders in runners was increased by following a 'special diet'. The frequency of menstrual cycle disorders in runners, however, did not differ significantly from the control group.

Sweet, Salty, and Umami Taste Sensitivity and the Hedonic Perception of Taste Sensations in Adolescent Females with Anorexia Nervosa.

OBJECTIVE: The aim of this study was to perform analysis of sensitivity to sweet, salty, and umami tastes based on three measurement methods and of the hedonic perception of taste sensations in adolescent females with anorexia nervosa (AN). The aim of the research was to confirm the results of other authors in terms of the perception of sweet and salty taste in patients with AN, and then develop knowledge about the perception of umami taste, which is still insufficiently studied. METHOD: A total of 110 females with an age ranging from 13 to 19 years, including 50 newly diagnosed patients with a restrictive subtype of AN and 60 healthy controls participated in gustatory research involving analyses of taste perception (recognition thresholds, ability to identify the taste correctly, taste intensity, and hedonic response) applying the sip and spit method. RESULTS: Females with AN showed reduced sensitivity to salty taste and increased sensitivity to umami taste and, more often than healthy controls, wrongly classified the taste of solutions with a low sucrose concentration. Patients with AN assessed the sodium chloride and monosodium glutamate tastes less negatively than did control participants, and they did not show differences in their hedonic assessment of sucrose. CONCLUSIONS: The taste sensitivity alterations in females with AN demonstrated in this paper do not entail decreased hedonic assessment of taste experiences. Based on our results, we cannot consider the observed variation in taste sensitivity in patients with AN to be a factor that increases their negative attitude toward food consumption.

Diagnosis of level of knowledge, opinion and pro-health behavior of Silesian voivodeship inhabitants concerns vitamin D and risk factors of its deficiency.

INTRODUCTION AND AIM OF THE STUDY: Vitamin D deficiency is a common problem in Poland and worldwide. In the light of recent epidemiological studies, D hypovitaminosis causes not only skeletal diseases, but also other chronic diseases such as immunodeficiency or some types of cancer. The proper knowledge can significantly determine pro-health behaviour, therefore the aim of the study was to analyse the knowledge, opinion and social behaviour regarding vitamin D. MATERIAL AND METHODS: The survey was conducted among 300 Silesian Voivodeship inhabitants (178 women and 122 men) using an anonymous survey containing 40 questions. RESULTS: 59% of people were aware of solar radiation, as a main source of vitamin D in the human body. Sea fish, as the main dietary vitamin D source, were known to 58% of respondents. The highest number of indications (67%) had dairy products, which are poor sources of cholecalciferol. 37% of people were aware that even a well-balanced diet was not able to provide the required daily dose of vitamin D. 78% of people in the study group were aware of the calcaemic effect of vitamin D. Only 9% of respondents were aware of the safe amount of daily sun exposure, sufficient for vitamin D synthesis, while 69% indicated periods of time longer than recommended. 76% of the respondents showed a positive attitude to sun exposure. Taking vitamin D supplementation was declared by 45% of the study participants, while a serum 25(OH)D level was tested only by 6.5% of the respondents. CONCLUSIONS: Insufficient knowledge about the vitamin D sources among the Silesian Voivodeship inhabitants, misconceptions about the possibility to reach adequate blood levels through the diet, and at the same time low consumption of products rich in vitamin D and its supplements, may be the causes of vitamin D deficiencies.

The Impact of Kinesiology Taping on a Greek Foot with a Hammertoe-A Case Report.

BACKGROUND AND OBJECTIVES: Hammertoe, one of the most common toe deformities, causes pain due to overloading of the periarticular tissues and skin lesions. Additionally, it results in problems with footwear choice, an unattractive foot appearance and a deterioration in quality of life. The most common treatment for rigid and advanced deformities is surgery, and these procedures are widely described in literature. If the changes in the interphalangeal and metatarsophalangeal joints are flexible (that mean they undergo correction without causing pain) or surgery is not possible, conservative treatment should be considered. No research, however, has been found detailing this treatment method. Conservative treatment includes the Kinesiology Taping (KT) method, which involves applying taping to correct deformities. This report describes the effect of KT treatment in a female patient with hammertoes. MATERIALS AND METHODS: Anthropometric foot measurements (3D scanner) and foot loadings (baropodometric platform) are presented before KT applying, immediately after tapes application and after tapes removal following one month of use. RESULTS: After using KT application parameters such as: foot length, maximum foot load, load under the area of the metatarsals II-III changed. CONCLUSION: Kinesiology Taping seems to be a symptomatic form of treatment of the effects of lesser toes deformity, therefore it is a good alternative for patients who do not want or cannot undergo surgery.

Effect of Hallux Valgus Correction with Kinesiology Taping on Hindfoot Position. Pilot Study.

BACKGROUND: Hallux valgus is the most common deformity of the forefoot. It has a multifactorial aetiology, with hindfoot valgus considered one of its causes. The aim of this study was to evaluate hindfoot position and loading pattern after a treatment of Kinesiology Taping (KT) for the mechanical correction of hallux valgus. MATERIAL AND METHODS: The study involved 25 feet with hallux valgus deformity and hindfoot valgus. The hallux valgus angle (HVA) and hindfoot angle were assessed with a 3D scanner. Hindfoot loading pattern was examined with a baropodometric platform while standing and during gait. Measurements were taken on the following three occasions: before and immediately after KT placement as well as after a month of taping. RESULTS: The KT treatment had a significant influence on the hindfoot angle (p<0.001) and HVA (p<0.001) measured while standing and on lateral heel loading in dynamic conditions during gait (p<0.01). CONCLUSIONS: 1. KT decreased HVA and improved hindfoot position while standing in the pilot study participants. 2. KT exerted a corrective influence on the foot loading pattern in patients with hallux valgus and hindfoot pronation. 3. The foot position correction and normalisation of foot loading achieved in the pilot study provide a basis for further research on KT effectiveness in patients with hallux valgus and hindfoot pronation.

The Assessment of Quality of Products Called Sandalwood Oil Based on the Information Provided by Manufacturer of the Oil on Polish, German, and English Websites.

BACKGROUND: Sandalwood oil is one of the most valuable raw materials worldwide. As a highly valued product, it has its own regulations based on the ISO 3518 standard, which clearly informs producers, distributors, and consumers of the requirements to be met. The aim of this study was to assess the quality of products called sandalwood oil based on the information provided by the manufacturer of the oils on Polish, German, and English websites. METHODS: A Google search was utilized to collect data on sandalwood oil offered by producers and distributors in Polish and foreign markets. Information from 50 websites in each of the aforementioned languages, including the description of sandalwood oil properties on websites, method for using it, safety limitations, and presence of a product description consistent with the INCI recommendations, was gathered using Microsoft Excel software and was analyzed. The information that enabled us to estimate the quality of the oils was the botanical name of the oil-bearing plant and the price. Good-quality oils were considered to be oils with the botanical name Santalum album in the description and with a price not considerably less than the price of white sandalwood oils sold by reliable distributors who control the quality of the oils by chromatography. Ultimately, the lower price limit for one milliliter of the oil was established as PLN 21. Results and Conclusions. Good-quality sandalwood oils derived from the Santalum album plant at a price equal to or greater than the chromatographically tested items amounted to a negligible percentage of products sold online. Without knowing the botanical name of the essential oil plant and the price range of unadulterated sandalwood oil, the likelihood of buying a reliable product is low on all of the analyzed websites, with the lowest probability being observed on the Polish websites.

The Influence of Running and Dancing on the Occurrence and Progression of Premenstrual Disorders.

Background: The aim of the study was to assess the influence of both physical activity, such as running and dancing, and the personal characteristics of the studied women on the occurrence and progression of premenstrual disorder (PMD). Methods: We surveyed 414 women aged 22-48 who were experiencing the menstrual cycle but not using hormonal contraception. There were two physically active groups, runners (N = 215) and Argentine tango dancers (N = 94), and there was one group not undertaking any physical activity-the control group (N = 104). The research was conducted using the researchers' own questionnaire. Results: The number of days of PMD symptoms in the tango vs. runner vs. control groups are as follows: pre-bleeding (mean: 4.14 vs. 4.86 vs. 4.85; p = 0.024), after the onset of bleeding (mean: 1.76 vs. 2.39 vs. 2.16; p = 0.001), and in total (mean: 5.94 vs. 7.25 vs. 7.01; p < 0.001). The regression analysis results without grouping results are as follows: the number of days of symptoms before bleeding and menarche (B: -0.16; 95% CIs: from -0.29 to -0.04; p = 0.011), the total duration of symptoms and menarche (B: -0.17; 95% CIs: from -0.32 to -0.01; p = 0.036), lower abdominal pain and age (B: -0.05; 95% CIs: 0.92-0.98; p = 0.002), diarrhoea (B: -0.08; 95% CIs: 0.88-0.97; p < 0.001), tearfulness, depressive states and age (B: -0.06; 95% CIs: 0.91-0.97; p < 0.001), skin problems and age (B: -0.05; 95% CIs: 0.92-0.98; p = 0.004), joint pain and age (B: -0.09; 95% CIs: 0.86-0.96; p = 0.001), pain in the lumbar spine (B: -0.06, 95% CIs: 0.91-0.98; p = 0.001), water retention and BMI (B: 0.09; 95% CIs: 0.92-0.98; p = 0.007), and water retention and menarche (B: -0.19; 95% CIs: 0.73-0.94; p = 0.003). Information: generally there is one regression model, we have several here, we have a bit the description. Conclusions: Physical activity such as dancing (tango) shortens the duration of PMD symptoms but does not completely eliminate them. Running does not have as beneficial an effect on symptom relief as dancing. Current age, age when menstruation began (menarche), and BMI were revealed to be important factors influencing the symptoms of premenstrual disorders.

Implications of Argentine Tango for Health Promotion, Physical Well-Being as Well as Emotional, Personal and Social Life on a Group of Women Who Dance.

BACKGROUND: The aim of the research was to determine the effect that dance has on the promotion of health, physical well-being, as well as the emotional, personal and social life of women who dance. In addition, the impact of the physical activity of long, often all-night dancing events on women's health was investigated. This included possible disturbances in their monthly cycle and circadian rhythm, taking into account symptoms of biological rhythm disturbances. METHODS: The study involved 214 women: tango group: 109, sedentary group: 105. The Mann-Whitney U and chi2 tests were used to compare the groups, as well as multiple ordinal regression to analyse individual predictors of missed menstrual periods. RESULTS: The tango vs. sedentary groups did not differ in the duration of menstrual bleeding, the degree of pain during menstruation, the regularity of menstruation, the number of regular monthly cycles per year, and amenorrhea. Intermenstrual spotting was more common in dancers (tango 12.8% vs. sedentary 4.8%; p = 0.038). The frequency of missed periods was not increased by any of the assessed aspects. In 59.6% of female dancers, milongas caused disturbances in circadian rhythms, including extreme fatigue and drowsiness (36.7%), 66.0% of the dancers mentioned only positive aspects of Argentine Tango's impact on their personal life. CONCLUSIONS: tango plays a positive and multifaceted role in the lives of dancers and fulfils the need for social contact. The physical effort put into this form of physical activity does not significantly affect the menstrual cycle, and thus the reproductive functions, and can be recommended as an attractive and safe form of physical recreation for women.

The Influence of Short-Term Kinesiology Taping on Foot Anthropometry and Pain in Patients Suffering from Hallux Valgus.

Background and Objectives: Hallux valgus, one of the most common foot disorders, contributes to the formation of pain, changes foot proportions and hinders everyday functioning. In this study we wanted to verify if kinesiology taping improves hallux valgus and affects the position as well as reducing pain. Materials and Methods: Forty feet with hallux valgus were examined and the parameters were measured at three stages: before the kinesiology taping was applied, just after its application and after a month of use. Measurements were taken with a 3D scanner and a baropodometric platform. Results: When taping was applied, the hallux valgus angle decreased statistically significantly compared with pre-taping (p < 0.01). The use of taping for a month significantly reduced this angle compared with pre-taping (p < 0.05). Parameters such as foot length, the surface of the hindfoot and forefoot and hindfoot pressure on the ground changed. A change in the hallux position due to the taping produced significant changes in the perception of pain (p < 0.001). Conclusion: Kinesiology taping acts on the hallux valgus and foot position mechanically. This makes kinesiology taping an effective method of conservative treatment for patients who are not qualified for surgery.

The short-term effectiveness of Kinesiology Taping on foot biomechanics in patients with hallux valgus.

BACKGROUND: Hallux valgus, one of the most common foot disorders, contributes to the formation of pain and changes foot biomechanics. OBJECTIVE: To assess the impact of Kinesiology Taping (KT) on foot loading during gait in patients with hallux valgus. METHODS: Forty feet with hallux valgus were examined. Patients wore the KT for a month and the parameters of the foot during gait on a baropodometric platform were measured three times: before taping, immediately after application of taping and after one month's use. RESULTS: The taping had a statistically significant effect on dynamic foot measurements. The maximum and mean foot load (p< 0.001), foot surface (p< 0.001), ratio of forefoot to hindfoot load (p< 0.01) and the proportions of the lateral and medial foot loading (p< 0.05) all changed. During gait cycle, taping significantly increased the load and surface at the first metatarsal head (p< 0.001) while there was a decrease around the second to fifth (p< 0.001) metatarsal heads. CONCLUSIONS: Using KT to correct a hallux valgus is a procedure that has an impact on the dynamic parameters of the foot during gait. The use of this method could become an alternative to surgical treatment for those patients, who have any contraindication for surgery.

The nutritional habits of women who train in fitness clubs and the potential implications on menstrual cycle disorders.

INTRODUCTION: Nutrition is one of the most important lifestyle elements influencing health and contributing to the correct functioning of the human body. OBJECTIVES: The aim of the research was to analyse the nutritional behaviour and disorders of the monthly cycle in women training in fitness clubs (F-Fitness) compared to women who did not participate in any training (C- Control). MATERIAL AND METHODS: 248 women, aged 21.5 ± 3 years, took part in the study (F:120, C:128). The author's survey was used for the research. The U Mann-Whitney and Chi2 tests were used for comparisons of the groups and multiple regression analyses were used for continuous outcomes and multiple logistic regression analyses for binary outcomes. RESULTS: In comparison with the control group women training in fitness clubs avoided sweets, fried food, highly processed products as well as snacking between meals. The Fitness Group ate more meals during the day, wherever possible at fixed times, ate vegetables and fish more frequently, drank more fluids. The Fitness Group used protein supplements and "special diets" more often, including balanced, starvation and calorie restricted diets and admitted to more frequent compulsive overeating. In the Fitness Group menstrual disorders were more frequent, F vs C: 30% vs 18%. Factors increasing menstrual disorders included: a special diet: OR 3.85, (95% CI 1.11-13.36), p=0.033 and starvation diet: OR 4.15, (95% CI 1.84-9.33), p= 0.001. The factors which reduced menstrual cycle disorders were: a balanced diet: OR 0.09, (95% CI 0.01-0.58); p=0.011 and snacking between meals: OR 0.43, (95% CI 0.24-0.80); p=0.008. CONCLUSIONS: The factors that increased the possibility of menstrual disorders were: special and starvation diets. Conversely, the reduction in the probability of menstrual disorders was associated with a balanced diet and snacking between meals.

How reliable is BMI? Bioimpedance analysis of body composition in underweight, normal weight, overweight, and obese women.

BACKGROUND: The human body consists of water, proteins, lipids, carbohydrates, and minerals that build cells, tissues, and organs. In healthy people, the content of these molecules remains nearly constant. The body mass index (BMI) is commonly used to classify abnormal body composition among adults. According to the WHO, a high BMI is a major risk factor for many diseases. Bioelectrical impedance analysis is a commonly used method for assessing body composition in clinical practice and medical research. AIMS: The aim of this study was to identify the advantages and disadvantages of using BMI in diagnosis of underweight, overweight, and obesity, by comparing the value of the index with the values of body composition analysis parameters. METHODS: A total of 267 healthy women 18 to 35 years of age participated in this study. Bioelectrical impedance analysis was performed on all participants at the beginning of the experiment with an InBodyS10 device. RESULTS: In the BMI categories of overweight and obese, only women with excessive BFM were measured with BIA. The BMI category of normal body weight, apart from women with normal body composition, includes people with both deficient and excess body components, e.g., body fat or lean body mass. The BMI category of underweight includes women with different body compositions as well as people with excessive fat content. CONCLUSIONS: The BMI is useful to provide a warning of excessive fat content in overweight and obese women, whereas among normal weight and underweight women, it may mask various types of body composition defects.
