The aim of the study was to identify the effect of compensatory mechanisms on the prevalence of sagittal spinal curvature deformity and musculoskeletal pain and to assess the interrelationships between those components in sitting volleyball players. Twenty-one elite Polish sitting volleyball players (age = 34.1 ± 7.5, BM = 77.9 ± 16.0) participated in the study in which direct participatory systematic observation and a non-invasive method were used. Both objective (anthropometric, spinal curvature–Idiag M360) and subjective (musculoskeletal ailments–NMQ = 7) measurements were performed. The Statistica 13.3 software package was used for statistical analyses. The neck, lower back (43%), and upper back (38%) were the most frequently reported painful areas. Of all participants, 76% reported sagittal spinal deformities. In the habitual position, the results indicated moderate correlations (r = 0.5, p < 0.05) between the lumbar concavity of the back and low back pain (LBP) and between thoracic convexity and LBP (r = 0.4, p < 0.05). Internal and external compensation have an effect on the prevalence of spinal curvature deformities in the sagittal plane, with thoracic hyperkyphosis (38%) and lumbar hyperlordosis (33%) being the most common. More severe lower and upper back pain were correlated with greater angles of thoracic kyphosis and lumbar lordosis in the habitual position.
Objectives: Vestibular rehabilitation leads to a gradual diminution of the subjective and objective symptoms that accompany the vestibular disorders. The aim of the study was to compare the impact of 2 different types of vestibular rehabilitation on vestibular compensation in patients with chronic unilateral vestibular dysfunction. Material and Methods: The study was conducted on a group of 58 subjects (43 females and 15 males) aged 40-64 years, who presented with chronic unilateral vestibular dysfunction and were hospitalized. The patients were randomly assigned to either of the 2 groups established. The study was conducted in a 6-week period. Group 1 consisted of patients who underwent customized group vestibular rehabilitation in an outpatient setting. The program was performed once a week for 1 h 30 min, under the supervision of a physiotherapist and a physiatrist. Group 2 was instructed to perform Cawthorne-Cooksey exercises and simple balance exercises twice a day for 15 min. Results: An improvement in the outcomes of the Dynamic Gait Index as well as the Berg Balance Scale was statistically significant for group 1. The time for fulfilling the task in the Timed Up and Go Test improved in both groups (p < 0.05). The subjective estimation of the symptoms evaluated with the use of the Dizziness Handicap Inventory and the Visual Analogue Scale revealed a statistically significant improvement in both groups, yet it was higher in group 1. Conclusions: The compensation achieved after 6 weeks of the customized, supervised outpatient rehabilitation program in group 1 was superior to the results of the home-based unsupervised Cawthorne-Cooksey and balance exercises.
BACKGROUND: One of the complications of obesity is low back pain, frequently associated with postural disorders. Body adiposity index (BAI) can be calculated without weighing, which may be rendered useful in settings where measuring accurate body weight is problematic. OBJECTIVE: The aim of this study was to compare two indices of somatic structure, i.e., BAI and BMI regarding their accuracy (specific and sensitive) in predicting postural aberrations. METHODS: The study group comprised of 1281 participants aged 20–22 years, who were students from universities in southern Poland. Anteroposterior spinal curvatures were measured using the Rippstein plurimeter. All subjects were measured for body height (BH) and mass, waist and hip circumference (WC and HC, respectively). RESULTS: In both male and female groups classified according to BAI cut-off points, a significant linear relationship was noted for the lumbar lordosis angle, i.e., the latter increased along with the BAI increase. The analysis of variance confirmed statistically significant differences in lordosis angles in both groups (women f= 19.6, p< 0.001; men f= 21.18, p< 0.001). These data evidenced a weak relationship between LL and the BAI. Pearson correlation coefficient (r) between LL and BAI was 0.2 and 0.21 for men and women, respectively. CONCLUSIONS: We concluded that, contrary to BAI, BMI value did not indicate a significant difference in lumbar lordosis angle between normal weight and obese participants (women and men).
Background: BMI is known to have limited accuracy, which is different for males and females with similar body fat content. That is why Bergman et al. (Obesity 2011;19:1083-1089) introduced an alternative variable of obesity, called the body adiposity index (BAI). Their primary research was conducted in samples of Mexican-American and African-American populations. The objective of our research was to investigate the sex-specific relationship between both BMI and BAI and body fat content in a healthy Caucasian population. The accuracy of both indexes was compared. Methods: 684 women and 528 men aged 20-22 years with Caucasian origin only participated in the study. Participants were students of universities in southern Poland. They had no indication of cardiometabolic problems, as evaluated by interview. Results: The study revealed that BAI is a more sensitive method in assessing obesity in Caucasian males rather than BMI. In the population of Caucasian women BAI results indicate a significant underestimation of obesity. Conclusion: The fact that there is a high statistical correlation between BAI and % fat mass among obese and overweight men and women suggests that BAI could be highly specific provided that the BAI cutoffs will be adapted to the European population.
The study group was characterized by excess body mass and insufficient levels of physical activity. Body mass index and waist circumference are sufficient indicators for identifying obesity in adults with intellectual disability.
StreszczenieWstęp: W Polsce 85% ludności dorosłej zgłasza dolegliwości bólowe odcinka lędźwiowego kręgosłupa, a 70-80% osób do 20. roku życia doświadczyło takich dolegliwości. Najczęstszą pierwotną przyczyną zapalnego bólu krzyża (ZBK) jest utrata lordozy lędź-wiowej, która zapoczątkowuje zmiany w geometrii innych odcinków kręgosłupa i wpływa na ustawienie kończyn. Celem badania jest zweryfikowanie związku między głównymi krzywiznami kręgosłupa w płaszczyźnie strzałkowej, tj. lordozą lędźwiową i kifozą piersiową, a dolegliwościami bólowymi w różnych częściach narządu ruchu w grupie 20-letnich osób u progu stabilizacji ontogenetycznej. Założono, że nadmierne wychylenie odcinka lędźwiowego i zwiększony dysbalans piersiowo-lędźwiowy jest czynnikiem sprzyjającym ZBK. Słowa kluczowe: studenci, dysbalans strzałkowy, bóle krzyża, NMQ, plurimetr Rippsteina, płaszczyzna strzałkowa Abstract Background: In Poland, about 85% of the population report low back pain (LBP) symptoms overall. Moreover, 70-80% of people aged below 20 have already experienced back pain. The primary cause of LBP is the loss of spinal lordosis, which initiates changes in geometry of the spine and has impact on limb arrangement. The aim of the study was to attempt to verify the relationship between the 2 main curvatures of the spine and its relation to symptoms in different parts of the musculoskeletal system, in a group of adults. It was assumed that hyperlordosis of the lumbar spine and misbalance of the thoraco-lumbar junction are risk factors for LBP. Material and Methods: The study coverd 231 first-year students, (aged 19-21) of the University of Economics in Katowice. There were 103 men aged 19.5±0.8 years and 128 women aged 19.6±0.8 years. The students completed the Nordic Musculoskeletal Questionnaire (NMQ): 7 days (NMQ7) and 6 months (NMQ6). A Rippstein's plurimeter, was used to measure the angles of thoracic kyphosis (KTH) and lumbar lordosis (KLL). Cut of points was set at 30±5. Results: The results indicate strong and very strong correlation (r = 0.6 and r = 0.8, p < 0.05) between the concave of the back and LBP, which may suggest the relationship between these symptoms and the increased lordosis. Conclusions: Postural defects in the sagittal plane may predict the occurrence of pain. The results of the study indicate a higher frequency of pain in people with a higher angle of lumbar lordosis.

The disabled population varies significantly in regard to physical fitness, what is conditioned by the damage to the locomotor system. Recently there has been an increased emphasis on the role of competitive sport in enhancing health and the quality of life of individuals with disability. One of the sport disciplines of Paralympics is the flat bench press. The bench press is one of the most popular resistance exercises used for the upper body in healthy individuals. It is used not only by powerlifters, but also by athletes in most strength-speed oriented sport disciplines. The objective of the study was to compare neuromuscular control for various external loads (from 60 to 100% 1RM) during the flat bench press performed by an elite able-bodied athlete and an athlete with lower limb disability. The research project is a case study of two elite bench press athletes with similar sport results: an able-bodied athlete (M.W., age 34 years, body mass 103 kg, body height 1.72 m, 1RM in the flat bench press 200 kg) and a disabled athlete (M.T., age 31 years, body mass 92 kg, body height 1.70 m, 1RM in the flat bench press 190 kg). The activity was recorded for four muscles: pectoralis major (PM), anterior deltoid (AD), as well as for the lateral and long heads of the triceps brachii (TBlat and TBlong). The T-test revealed statistically significant differences between peak activity of all the considered muscles (AD with p = 0.001; PM with p = 0.001; TBlat with p = 0.0021 and TBlong with p = 0.002) between the 2 athletes. The analysis of peak activity differences of M.W and M.T. in relation to the load revealed statistically significant differences for load changes between: 60 to 100% 1RM (p = 0.007), 70 to 100% 1RM (p = 0.016) and 80 to 100% 1RM (p = 0.032). The flat bench press performed without legs resting firmly on the ground leads to the increased engagement of upper body muscles and to their greater activation. Isolated initial positions can be used to generate greater engagement of muscle groups during the bench press exercise and evoke their higher activation.
Background: The last decade has seen the dynamic development of Paralympic sport, including the development of training facilities and training methods that allow for the achievement of results at the highest level in this group. This may be associated with an increased risk of injury and traumas. This study aimed to evaluate the prevalence and locations of injuries and the types of trauma suffered by goalball players. Methods: The study covered 43 players (24 women and 19 men) of the Goalball European Championship. A questionnaire survey was conducted. Results: The injuries were reported by 44%. Most often they concerned the upper limbs (92%). Positive correlations were found between age and prevalence of pelvis and knee joint injuries, whereas negative correlations occurred between competitive experience and the prevalence and location of injuries in the area of the upper limb. The highest percentage of trauma was found for epidermal abrasions, contusions, and dislocations. A negative correlation was observed between age and the prevalence of epidermal abrasions, whereas a positive correlation occurred between age and the prevalence of sprains and dislocations. The competitive experience was negatively correlated with the prevalence of abrasions and contusions and positively correlated with the prevalence of sprains and dislocations. A statistically significant correlation was found between body mass (BM) and the prevalence of injuries. In 23% of cases, training was interrupted for more than one month, whereas in 43%, the break was below one month. Conclusions: Playing position in goalball does not affect the prevalence of injuries and traumas, while body mass has a moderate effect on the prevalence of these events. The age of the subjects and their sports experience impact significantly on the prevalence and types of injuries.
