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.

The aim of this study was to compare the thoracic and lumbar curvatures and pelvic tilt in relaxed standing and maximal trunk flexion among highly-trained young athletes from three different sports disciplines. Thirty-two male canoeists, 30 male kayakers and 24 male tennis players were recruited for the study. The Spinal Mouse® system was used to measure the thoracic and lumbar sagittal spinal curvatures and pelvic tilt in relaxed standing and maximal trunk flexion in sitting with flexed (McRae & Wright test) and extended knees (sit-and-reach test). Significant differences were found in maximal trunk flexion tests among athletes. Kayakers and canoeists showed increased anterior pelvic tilt compared to tennis players in the McRae & Wright (p<.01) and decreased posterior pelvic tilt in the sit-and-reach (p<.001) tests; however, canoeists had increased posterior pelvic tilt compared to kayakers in the sit-and-reach test (p<.01). Canoeists had increased thoracic kyphosis curvature compared to kayakers (p<.01) and tennis players (p<.001) in the sit-and-reach test. Spinal sagittal curvatures and pelvic tilt in relaxed standing did not show significant differences. In conclusion, specific sport training may be associated with adaptations in the sagittal spinal curvatures and pelvic tilt when maximal trunk flexion positions are performed.

Context: Previous research has analyzed how the sport influences sagittal spinal curvatures in young athletes and has found that spinal curves may be modified as a consequence of repeated movement patterns and postures of each discipline. Objective: To analyze sagittal spinal alignment by equestrian discipline and its relation to training load, and to describe “sagittal integrative morphotype” in young riders. Design: Observational descriptive study. Setting: Training room. Participants: A total of 23 riders (aged 9–17 y)—13 dressage riders (3 males and 10 females) and 10 show jumping riders (5 males and 5 females)—participated voluntarily. Main Outcome Measures: Mann–Whitney U test was applied to determine differences between riders’ characteristics (gender, discipline, and training load) and spine variables. Results: According to normality ranges for spinal curves, females showed an increase for lumbar curvature in standing position. It was found that show jumping riders manifested an increment in thoracic and lumbar curves while standing and an increase in the thoracic curvature in slump sitting. Statistically significant differences were found when lumbar curvature, “sit and reach” distance, and lumbo-horizontal angle in flexion were analyzed by gender in “sit and reach” test. No statistical significant differences were found when spinal curves in each position were analyzed depending on the training load. With regard to “sagittal integrative morphotype,” all riders presented a hyperkyphotic dorsal morphotype no matter what their discipline. As for the lumbar curve, dressage and show jumping riders presented a functional hyperkyphotic morphotype. Conclusions: It is important to note that many riders presented a sagittal imbalance for the thoracic and lumbar curves. Therefore, as the sagittal spinal misalignments persist and worsen over time, exercise programs to prevent or rehabilitate these imbalances in young riders will be needed. The “sagittal integrative morphotype” assessment is an essential tool in order to identify the spinal misalignment.

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.

Abstract Introduction: In physiotherapeutic diagnostic processes, various tools and methods may be used. However, price and availability may limit their daily use in clinical practice. Therefore, the suggestion that smartphones with specific applications may be useful as diagnostic tools can be found in the literature. However, before using them in clinical practice, it is important to verify their reliability. The aim of the study was to evaluate the consistency of measurements of the curvatures in the sagittal plane performed with the Saunders digital inclinometer and a smartphone application. Materials and methods: The study included 40 subjects aged 22-39 years (23.0 ± 3.7). All subjects had sagittal spinal curvatures (sacral slope - SS, lumbar lordosis - L, thoracic kyphosis - K, upper thoracic kyphosis - K1, lower thoracic kyphosis - K2) measured in both standing and sitting positions with the Saunders digital inclinometer and a smartphone application. Results: In measurements performed with the use of the Saunders inclinometer and the smartphone, no significant differences were found between the size of the curvatures of the spine in a standing position (SS 19° ±8.2 vs. 17° ±8.4 p=0.3; L 32° ±11.1 vs. 29° ±10.3 p=0.2; K 43° ±8.4 vs. 41° ±8.1 p=0.2; K1 31° ±7.2 vs. 29.0° ±7.3; K2 11o ±7.4 vs. 11.0° ±6.7) and a sitting position (SS 3.75° ±8.9° p=0.8; L 5.8° ±9.06 vs. 5.2° ±8.5 p=0.75; K 40.0° ±8.1 vs. 36.7° ±7.9 p=0.6; K1 25.8° ±7.1 vs. 24.9° ±7.1; K2 14.5° ±9.9 vs. 11.5° ±9.4). Conclusions: The examination of spinal curvatures in the sagittal plane using Saunders digital inclinometer and a smartphone application allows researchers to obtain reliable results. Therefore, smartphones can be used for an objective evaluation of the musculoskeletal system in daily clinical practice.

BACKGROUND: The child’s spine shows changes in posture and balance of its curvatures during growth and musculoskeletal spinal conditions are likely to develop, such as back pain (BP). OBJECTIVE: The purposes of this study were (a) to describe the sagittal spinal alignment in a relaxed standing position and (b) to analyze its association with BP among 8 to 12-year-old children. METHODS: This was a cross-sectional study. A total of 731 elementary schoolchildren (379 girls and 352 boys), from 16 Spanish schools, participated. An unilevel inclinometer was used to quantify the sagittal spinal curvatures (thoracic and lumbar) in a relaxed standing position. Sagittal spinal morphotype was analyzed by sex, age, weight, height, and BMI. Children’s parents or legal guardians filled in a questionnaire according to the children’s responses about the BP suffered in the previous week and the preceding year. RESULTS: The mean angular value of thoracic kyphosis was 36.08 ± 8.99∘ and significantly higher in males than in females (p= 0.036). In contrast, the mean value of lumbar lordosis was 32.11 ± 7.46∘, being higher in females than in men (p< 0.01). The thoracic curve tends to increase by age (p= 0.003). Children who had low back pain (LBP) in the previous week had a significantly greater lumbar curve (35.88 ± 8.20∘) than those who did not have LBP in the preceding week (32.24 ± 7.30∘). The angle for lumbar curvature was a small predictor of LBP occurrence in the assessed children (OR = 1.082 [small]; 95% CI = 1.009–1.160, p= 0.028). CONCLUSIONS: To conclude, almost 3/4 of the students were classified with normal thoracic kyphosis; however, 27.36% of the students had thoracic hyperkyphosis. Lumbar hyperlordosis was identified in 9.05% of the students, and was 2.5 times more frequent in girls. The lumbar curvature was a small predictor of LBP occurrence in the assessed children and the angle of lumbar curvature that most accurately identified individuals at risk of developing LBP was determined to be 33∘. The results of this study indicate the need to assess sagittal spinal curvatures at school during development ages.

Influence of Hamstring Muscles Extensibility on Spinal Curvatures and Pelvic Tilt in Highly Trained CyclistsThe purpose of this study was to determine the influence of hamstring muscles extensibility in standing, maximal trunk flexion with knees extended and on the bicycle in lower handlebar-hands position of highly trained cyclists. Ninety-six cyclists were recruited for the study (mean ± SD, age: 30.36 ± 5.98 years). Sagittal spinal curvatures and pelvic tilt were measured in the standing position, maximal trunk flexion with knees extended (sit-and-reach test) and while sitting on a bicycle in lower handlebar-hand position using a Spinal Mouse system. Hamstring muscles extensibility was determined in both legs by passive straight leg raise test (PSLR). The sample was divided into three groups according to PSLR angle: (1) reduced extensibility (PSLR < 80º; n = 30), (2) moderate hamstring extensibility group (PSLR = 80º; - 90º; n = 35), and (3) high hamstring extensibility (PSLR = > 90º; n = 31). ANOVA analysis showed significant differences among groups for thoracic (p < 0.001) and pelvic tilt (p < 0.001) angles in the sit-andreach test. No differences were found between groups for standing and on the bicycle position. Post hoc analysis showed significant differences in all pairwise comparisons for thoracic angle (p < 0.01) and pelvic angle (p < 0.001) in the sit-and-reach test. No differences were found in lumbar angle in any posture. In conclusion, the hamstring muscles extensibility influence the thoracic and pelvic postures when maximal trunk flexion with knees extended is performed, but not when cyclists are seated on their bicycles

The current study was designed to find out relationship between psychological skills and performance efficacy and mediating role of sportsmanship in domestic, national and international hockey players. It was a correlational research employing cross sectional research design in which the sample of 261 hockey players was recruited via purposive sampling. The assessment measures included Psychological Skills Scale for Hockey Players and Cricketers (Solomon, Malik & Kausar, 2019), Youth Sports Value Questionnaire-2 (Lee, Whitehead, & Ntoumanis, 2007) and Collective Efficacy for Sports Questionnaire (Short, Sullivan, & Feltz, 2009). Results showed a significant relationship between psychological skills, sportsmanship and performance efficacy in hockey players, however, perceivedpsychologicalsupport was found to be significant positive predictor of sportsmanship and sportsmanship coined as a significant positive predictor of performance efficacy. Furthermore, sportsmanship was found to be significant mediator between perceived psychological support and performance efficacy. This research will work as an empirical proof for Pakistan Hockey Federation (PHF) to conduct psychological skills training for hockey players for the enhancement of their performance efficacy by signifying theimportance of sportsmanship.

AbstractPurpose. Motor coordination is proposed to be a relatively stable age-related construct, unlikely to be influenced by aligned experiential factors such as intensive sport-specific training. The purpose of the study is to investigate if there are differences in motor coordination abilities among young artistic gymnasts, swimmers, and ice hockey players.Methods. The participants of the study were 508 female and 258 male adolescents (age, M = 12.80, SD = 1.10) comprising artistic gymnasts (n = 463), swimmers (n = 70), and ice hockey players (n = 233). The KTK-test protocol was used to analyse their gross motor coordination abilities.Results. The results of the study demonstrated that gymnasts scored better than ice hockey players and swimmers in the test of walking backwards along a beam, and better than ice hockey players in total motor coordination, hopping over an obstacle, and the test of moving sideways on wooden boards. However, ice hockey players scored higher than swimmers and gymnasts in the test of jumping from side to side. Subsequently, swimmers obtained better results in the test of moving sideways on wooden boards as compared with ice hockey players.Conclusions. The study results indicate that intensive sport-specific training may extend young athletes′ motor coordination characteristics in the ability areas representative of the sport in which they engage.

Summary Study aim: The aim of this study was to evaluate the influence of hatha yoga practices on the shaping of the anteroposterior (AP) spinal curvatures in students of the University of the Third Age, who participated in hatha yoga classes. Material and methods: 20 women and 5 men took part in the study. Hatha yoga classes were held once a week for 90 minutes over a period of 8 months along with additional exercises including basic positions of hatha yoga in home conditions 1-2 times a week for about 30 minutes. The inclination of the AP curvatures of the spine was measured twice, before and after the end of the classes. A Rippstein plurimeter was used for the measurements. R esults: Measurements of the angle of thoracic kyphosis before starting the series of hatha yoga classes and after finishing them showed a decrease in thoracic curvature in female (p < 0.01). In case of the angle of lumbar lordosis, a reduction in this curvature as a result of yoga techniques has been observed in women (p < 0.01) too. Amounts of AP curvatures of the spine, measured after completing the series of hatha yoga classes, fluctuated around correct values better than before taking them up. Conclusion: This study has shown that yoga training leads to an improvement in the habitual body posture in case of aggravating (excessive) AP curvatures of the spine.

The empirical study of the involvement of personal volition in the athletic success of young athletes aged 9 to 18 yearsis presented. The purpose of this study was to examine the relationship between individual characteristics of volitional processes and the grade of sport performance, determined by the sports qualifications of the respondents.The specifics and requirements ofdifferent kinds of sport have been considered. At the sample of young athletes from 9 to 18 years old (N = 145, M = 13,2 years) for some sports (athletics, rock climbing, football)significant regression models were built. Particular characteristics of volitional processes or their combination were discovered as predictors, and the athlete’s performance was a dependent variable. For other sports disciplines (boxing, rowing, swimming, rhythmic gymnastics), such models could not be identified. Moreover, we established that emotional self-control and determination have a joint effect on the grade of sport performance of athletes who was younger than 13, while for athletesfrom 14 to 18 years oldcommon predictors of performance from among volitional qualities was not found.
