Background Outdoor fitness training has become popular as a tool for improving the health, especially middle-aged and older adults. For this purpose, outdoor fitness equipment (OFE) have been installed in public areas. However, their safety and effectiveness are still unknown. The aim of the present research was to analyze the sagittal disposition of the spine and pelvic tilt during the use of OFE, and to determine the influence of anthropometric variables on these factors in middle-aged and older adults. Methods Seventy healthy volunteers, 56 women and 14 men (age: 63.14 ± 8.19 years) participated in the study. Sagittal spine disposition and pelvic tilt were measured using a Spinal Mouse®, in the relaxed standing position, and during the use of the OFE. In addition, kinanthropometry variables were also measured according to the guidelines of the International Society for the Advancement of Kinanthropometry. Results Regarding thoracic kyphosis, a significant decrease was found in thoracic kyphosis in the initial position (IP) in single bonny rider (SBR) (p = 0.006) and row (p = 0.046), and a significant increase in the final position (FP) in the row (p = 0.011), surfboard (p < 0.001) and air walker (p = 0.027) machines. In relation to the lumbar curvature and pelvic tilt, a significant decrease in lumbar lordosis and a decrease in pelvic anteversion were observed in the IP and FP in SBR and row; and in the bike (p < 0.001) machine. In the surfboard machine, a significant decrease in lumbar lordosis was found (p = 0.002), with no changes in pelvic tilt. According to the multiple linear regression analysis, the subjects with a higher cormic index and height were more at risk of increasing their thoracic kyphosis, decreasing lumbar lordosis and/or decreasing pelvic anteversion towards pelvic retroversion. Conclusions Middle-aged and older adults show spinal misalignments when using the OFE with respect to the standing position, showing a decrease in the thoracic kyphosis in IP of SBR and ROW, and a significant increase in the surfboard and air walker, and in the FP of Row, in the lumbar lordosis in all the OFE in sitting and some in standing, and in the pelvic anteversion in all the OFE in sitting. The variables height and the cormic index explained most of the changes in sagittal spine disposition.

Background Physiological sagittal spinal curvatures play an important role in health and performance in sports. For that reason, several scientific studies have assessed spinal morphology in young athletes. However, to our knowledge, no study has assessed the implications of Inline Hockey (IH) practice on sagittal integrative spinal morphotype in adolescent players. Objectives The aims of the present study were to describe habitual sagittal spinal posture in young federated IH players and its relationship with training load and to determine the sagittal integrative spinal morphotype in these players. Methods An observational analysis was developed to describe the sagittal spinal morphotype in young federated IH players. A total of 74 IH players from the Technification Plan organized by the Skating Federation of the Valencian Community (aged from 8 to 15 years) participated in the study. Thoracic and lumbar curvatures of the spine were measured in a relaxed standing position (SP), in a slump sitting position (SSP) and in maximum flexion of the trunk (MFT) to determine the “Sagittal Integrative Morphotype” of all players. An unilevel inclinometer was used to quantify the sagittal spinal curvatures. The Hip Joint Angle test was used to quantify the Lumbo-Horizontal angle in flexion (L-H fx) of all participants with a goniometer. Results When thoracic curvature was analyzed according to normality references, it was found that 64.9% of IH players had thoracic hyperkyphosis in a SSP, while 60.8% and 74.3% of players were classified as normal in a SP and in MFT, respectively. As for the lumbar curve, 89.2% in a SP and 55.4% in MFT were normal, whereas 68.9% of IH players presented lumbar hyperkyphosis in a SSP. Regarding the “Sagittal Integrative Morphotype,” only 17.6% of players were classified as “Normal” in the three measured positions for the thoracic curve, while 37.8% had “Thoracic Hyperkyphosis” and 41.8% presented “Functional Thoracic Hyperkyphosis.” As for the “Sagittal Integrative Lumbar Morphotype,” only 23% of athletes had a normal curve in the three positions, whereas 66.2% presented “Functional Lumbar Hyperkyphosis.” When the L-H fx was evaluated, the results showed that only 16.2% of the athletes were classified as normal. Conclusions Federative IH practice seems to cause specific adaptations in spinal sagittal morphotype. Taking into account the “Sagittal Integrative Morphotype” only 17.6% IH players presented “Normal Morphotype” with a normal thoracic kyphosis in the three measured positions, while only 23% IH players presented “Normal Morphotype” with a normal lumbar curvature in the three assessed positions. Furthermore, only 16.2% of IH players showed normal pelvic tilt. Exercise programs to prevent or rehabilitate these imbalances in young IH players are needed.

Background: Asymmetric dimethylarginine (ADMA) has recently been investigated as a risk marker for cardio- and cerebrovascular diseases. However, it remains unclear whether ADMA levels are related to the risk of stroke in the general Japanese population. Methods and Results: In this cross-sectional study, we examined 769 Japanese men (mean, 47 ± 5 years) who underwent health examinations. Each patient’s ADMA level and various vascular risk factors were assessed, and the predicted 10-year risk of stroke was calculated using the point-based prediction model for incident total stroke for Japanese from the Japan Public Health Center Study. In a multiple linear regression analysis, age, body mass index, estimated glomerular filtration rate, and current smoking status were significant independent determinants of the ADMA level. A significant odds ratio (OR) for high predicted stroke risk (10-year risk ≥ 5%) was noted in the highest quartile of ADMA level (OR, 2.47; 95% CI, 1.00-6.07) as compared to the lowest quartile, even after adjusting for potential confounding factors. A significant OR for high predicted stroke risk was also found for each standard-deviation increment in ADMA level (adjusted OR, 1.46; 95% CI, 1.10-1.92). Conclusions: An elevated ADMA level was significantly associated with an increase in predicted stroke risk, suggesting that the measurement of ADMA level may be useful for identifying middle-aged Japanese men at high risk for stroke.

Abstract Background and Aims The muscle strength of patients on hemodialysis (HD) is lower than that of community-dwelling older adults. Because decreased muscle strength, especially quadriceps isometric strength (QIS), has been reported to be a risk factor for increased mortality rate among patients undergoing HD, the prevention and correction of decreased QIS are very important in this population. Although some factors associated with decreased QIS among patients on HD have been reported, these factors remain unclear because patients on HD have many comorbidities with increasing age and prolonged HD vintage. In community-dwelling older adults, sleep disturbance is reported to be a factor associated with reduced muscle strength. In addition, the prevalence of sleep disturbance is higher in patients on HD. Therefore, it is necessary to investigate these associations in this population. We examined the association between QIS and sleep disturbances among patients receiving HD. Method This cross-sectional study included 211 outpatients undergoing HD three times a week. To evaluate QIS, a handheld dynamometer (μtas F-1; Anima, Tokyo, Japan) was used. Patients were asked to sit on a bench with their hip and knee flexed at an angle of 90°. They performed isometric voluntary contraction of the quadriceps for a maximum of 5 seconds, thrice, for both legs. The average of the right and left maximal QIS divided by the dry weight (%DW) was used in the analysis. Sleep disturbances were measured using the Athens Insomnia Scale (AIS), a self-administered questionnaire consisting of eight questions, each scored from 0 to 3. The total scores range from 0 to 24, with higher scores indicative of worse sleep quality. Clinical characteristics, including age, sex, body mass index, HD vintage, comorbidity score, serum albumin, C-reactive protein, and the Mini-Mental State Examination, were investigated. Multiple linear regression analysis and multivariable-adjusted restricted cubic splines with four knots were used to examine the association between QIS and sleep disturbances. Results The median age was 68 (interquartile range: 59–76) years, and 62% of the patients were men. In multiple linear regression analysis, the AIS score was extracted as a significant factor related to QIS after adjusting for clinical characteristics (regression coefficient: -0.45, 95% confidence interval: -0.84 to -0.05, p = 0.028). In the multivariable-adjusted restricted cubic splines, a nonlinear relationship was found between QIS and the AIS score even after adjusting for clinical characteristics. In addition, it was shown that QIS decreased significantly as the AIS score increased up to 6, which is the cutoff value for discriminating sleep disturbances (Figure). Conclusion Higher AIS scores were independently associated with decreased QIS among patients on HD. Future studies should investigate the causality between QIS and sleep disturbance in patients undergoing HD.

BACKGROUND: Idiopathic scoliosis is accompanied by postural alterations, instability of gait, and functional disabilities. The objective was to verify radiographic parameters (coronal and sagittal) of adolescents with idiopathic scoliosis (AIS) pre- and post-surgery with direct vertebral rotation (DVR), associated with type 1 osteotomies in all segments (except the most proximal) and type 2 in the periapical vertebrae of the curves. METHODS: A prospective study design was employed in which 41 AIS were evaluated and compared pre- and post-surgery. Scoliosis was confirmed by a spine X-ray exam (Cobb angle). Eight radiographic parameters were measured: Cobb angles (thoracic proximal and distal), segmental kyphosis, total kyphosis, lumbar lordosis, pelvic incidence, sacral slope, and pelvic tilt. RESULTS: The Cobb angle averaged 51.3∘± 14.9∘. Post-surgery, there were significant reductions for the following spine measurement parameters: Cobb angle thoracic proximal (p= 0.003); Cobb angle thoracic distal (p= 0.001); Cobb angle lumbar (p= 0.001); kyphosis (T5-T12, p= 0.012); and kyphosis (T1-T12, p= 0.002). These reductions showed the effectiveness of surgical correction to reduce Cobb angles and improve thoracic kyphosis. The values obtained for lumbar lordosis, pelvic incidence, sacral slope, and pelvic tilt were not significantly different pre- and post-surgery. CONCLUSION: The surgical technique of DVR in AIS proved to be effective in the coronal and sagittal parameters directed at Cobb angles and thoracic kyphosis in order to favor the rehabilitation process.

The aim of the present research was to improve the neglect behavior of pubertal children in an intervention program. Within the framework of the program, the main function of the spinal column and the strength and extensibility of the muscles responsible for posture were investigated. The participants included in the study are 7th grade children of the Neumann János Elementary School in Szombathely, Hungary, (nb=7); (ng=10). The Idiag M360 Spinal Mouse was used to investigate the physiological curvatures and main function of the spinal column before and after the program. The device was used to examine the children's spines in standing, bending forward and again in a standing position after the Matthiass test was performed. Pre-intervention (1) and post-intervention (2) data showed significant decreases in all assessed characteristics and similar increases in sacrum to hip ratio (Sac/Hip) (9.83±4.36 - 21.63±4.39); p<0.000.  The greatest change was found in the Th11/12 dorsal vertebral body angles (4.50±2.05 - -0.30±0.25); p<0.000. As a result of the postural improvement program, the degree of pelvic tilt and, in parallel, the physiological curvature of lumbar lordosis was reduced to within the age-specific reference values.

Abstract Social isolation is characterized by lack of social contacts and high degrees of loneliness. Feelings of loneliness and social isolation are linked to declines in cognitive functioning and increased risk of dementia. Previous research suggests that loneliness is more prevalent among Black and rural older adults compared to White and urban-dwelling older adults. Given these disparities, it is important to identify methods that reduce social isolation and loneliness among this population. Social technology, such as Facebook and Skype, is one possible way to connect with others. This study uses the Health and Retirement Study (HRS) dataset to examine racial and rural disparities in the relationship between social technology use and social isolation, loneliness, and social support among individuals age 50 and older. The overarching hypotheses are that (1) rural-dwelling older adults and older Blacks will report less social technology use compared to urban-dwelling and older White adults, and (2) there will be a negative relationship between loneliness and social technology use, and (3) a positive relationship between perceived positive social support and social technology use. Racial or rural disparities in these latter potential relationships are exploratory. Multiple linear regression analysis will be performed to assess these relationships. Preliminary correlational results indicate that, consistent with prior work, greater use of social technology was associated with higher social support (N=6,029; r=.29, p&lt;.001). However, contrary to our hypothesis, greater self-reported loneliness was associated with greater social technology (r=.09, p&lt;.001). Examination of potential racial and rural disparities in these relationships are currently underway.

This study aimed to identify social network types among older adults in rural China, to explore the relationship between social network types and the health of the older adults, and further, to examine the mediating role of social support in this relationship. A cross-sectional survey method was employed to investigate the health of adults aged 60 or older in rural areas of Hubei Province from 5 September 2018 to 15 October 2018; 405 samples were obtained. First, using k-means clustering analysis, we found five robust network types: diverse, restricted, family, friends and a specific type—family-restricted. Second, the results of multiple linear regression analysis showed that social network types were significantly associated with depressive symptoms and self-rated health in older adults. Older people with diverse friend networks were significantly associated with lower levels of depressive symptoms, whereas those with restricted and family-restricted networks were significantly associated with higher levels of depressive symptoms and lower levels of self-rated health. Finally, the results of multiple linear regression analysis confirmed that social support partially mediated the association of the identified social network types with depressive symptoms and self-rated health. Enriching the social network relationships of older adults and providing them with more social support should be conducive to promoting their mental and physical health.

This aim was to examine differences on lumbar lordosis and thoracic kyphosis in standing position by gender, age and weight status in healthy subjects using a noninvasive method. A total of 297 women (36.6 ± 7.3 years) and 362 men (39.8 ± 7.5 years) participated in this study. Participants were categorized according to the international BMI (kg/m2) cut-off points. Age was stratified by ten years increments starting from 20 y. Men showed smaller lumbar lordosis (17.3 ± 9.3) and larger thoracic kyphosis (42.8 ± 8.8°) than women (29.6 ± 11.3 and 40.4 ± 9.5° respectively; bothp< .001). Older groups presented smaller lumbar lordosis and larger thoracic kyphosis values compared with the 20–29 y group (20.9 ± 10.4, 20.8 ± 11.2 and 23.6 ± 12.6° for ≥50, 40–49 and 30–39 y, respectively vs. 26.7 ± 12.2° for 20–29 y in lumbar lordosis and 42.6 ± 9.8, 42.61 ± 8.7 and 41.8 ± 8.9° for ≥50, 40–49 and 30–39 y, respectively vs. 37.5 ± 10.9° for 20–29 y in thoracic kyphosis; bothp< .05). Finally, overweight and obese groups showed smaller lumbar lordosis (19.4 ± 11.1 and 20.9 ± 11.8° respectively) and larger thoracic kyphosis values (42.7 ± 8.9 and 42.8 ± 9.4° respectively) compared with nonoverweight participants (25.1 ± 12.4 and 40.6 ± 9.2° for lumbar lordosis and thoracic kyphosis respectively; allp< .05). However, when gender, age and weight status were take into account all together only gender seems to influence the lumbar lordosis curvature. The results of this study suggest that gender could be the only determinant factor of lumbar lordosis in healthy people.

Abstract Background Gaining proficiency in Bharatanatyam dance form necessitates maintenance of different postures for prolonged duration. These repetitive movements place tremendous physical demands on the body at young age and may alter the postural profile of the dancer. The study aimed to evaluate the differences in terms of posture between female Bharatanatyam dancers and age-matched non-dancers. A cross-sectional study was conducted in 40 female Bharatanatyam dancers and 40 age-matched female non-dancers in the age group of 18 to 30 years. Analysis of erect standing posture of dancers and non-dancers was conducted in a reserved environment using a photogrammetric method. Static photographs of the subjects were taken in the sagittal plane. The measurement of the angles of the digitized photographs was performed using KINOVEA 0.8.15 software. Head protrusion angle, cervical lordosis angle, thoracic kyphosis angle, lumbar lordosis angle, and pelvic tilt angle were evaluated. Results There was no significant difference between the dancers and non-dancers with respect to head protrusion angle (p = 0.081), cervical lordosis (p = 0.15), and thoracic kyphosis (p = 0.33). Significant differences were identified between the dancers and non-dancers for lumbar lordosis (p = 0.00) and pelvic tilt (p = 0.00) using independent t test with dancers. Higher values of lumbar lordosis and pelvic tilt were observed in dancers. Conclusion Increased lumbar lordosis and anterior pelvic tilt were observed in Bharatanatyam dancers as compared to non-dancers. Hence, it is vital to establish preventive measures like postural re-education, muscular balance, and flexibility to prevent erroneous postural patterns capable of causing pain and injuries.

Introduction: Data suggesting that cystatin C levels are linked to obesity, apart from renal pathology, are conflicting. The aim of the study was to explore the potential association between serum cystatin C levels, anthropometric, and cardiometabolic parameters in healthy middle-aged adults.Methods: A total of 132 participants (mean age 56.2 ± 6.73 years, 69% females) were included in this cross-sectional study. Anthropometric and biochemical parameters, as well as blood pressure, were obtained.Results: Obese participants displayed higher cystatin C levels than normal-weight participants (p < 0.001). Multiple linear regression analysis revealed that waist circumference (WC) (Beta = 0.376, p < 0.001) and estimated glomerular filtration rate (Beta = -0.484, p < 0.001) were independently associated with cystatin C levels (R2 = 0.447; p < 0.001).Conclusions: Cystatin C is associated with abdominal obesity independent of renal function. Its relationship with changes in other target organs  should be determined.
