Background: Flatback Syndrome (FBS) is a common type of adult spinal deformity (ASD) characterized clinical by loss of lumbar lordosis. This condition develops due to numerous reasons including complications from previous thoracolumbar instrumentation. Patients with FBS typically fail conservative measures and require surgical intervention. The goal of surgical management is normalization of radiographic parameters including lumbar lordosis, pelvic tilt, and age-adjusted sagittal vertical axis. Variations of osteotomies and interbody fusions have been used to treat FBS with variable outcomes. The objectives of this paper are to describe observations and lessons learned in the complex treatment of Flatback Syndrome through illustrating 5 unique cases. Observations: 5 illustrative cases of spinal deformity surgery for the treatment of flatback syndrome were presented and highlight surgical techniques and strategies for deformity correction including: various osteotomies, interbody placement, multi-rod constructs and anterior column reconstruction. Lessons: Restoration of sagittal balance postoperatively is critical in reducing the risks of flatback syndrome and proximal junctional kyphosis. Patient-specific risk factors and preoperative radiographic parameters should be used to tailor individualized treatment plans prior to surgical management of flatback syndrome. Improved awareness of the number of technical options available for patients with ASD is critical to selecting a patient-specific plan.

The objective of this study was to evaluate the agreement between the use of body mass index (BMI), the conicity index (CI), the waist-to-height ratio (WHtR), and body fat percentage (%BF), estimated via the Deurenberg equation, in the diagnosis of excess adiposity in schoolchildren. This cross-sectional study took place in 2023, with an anthropometric assessment of 1,459 kindergarten and elementary school students from municipal schools and municipal early childhood education centers in the municipality of Diamantina, Minas Gerais. Anthropometric diagnoses obtained through BMI, CI, WHtR, and %BF were compared to verify possible agreement between them according to sex and age group. For this analysis, Cohen's kappa and Fleiss tests were applied. A p value less than 5% was considered significant. Excess adiposity was identified in 9.5% of the schoolchildren by BMI, in 11.7% by WHtR, in 16.7% by CI, and in 20% by %BF. Regardless of sex, the WHtR showed moderate agreement with BMI (Cohen's kappa: 0.426 for girls and 0.425 for boys; p value <0.001) and with %BF (kappa: 0.515 for girls and 0.494 for boys; p value <0.001). WHtR, regardless of age, showed moderate agreement with %BF (<6 years - Cohen's kappa= 0.527, ≥6 years - 0.502; p value <0.001) and weak agreement with CI and BMI among those under six years of age. However, it was strongly correlated with BMI among schoolchildren ≥6 years (Kappa: 0.619; p value <0.001). The results of this study show that the WHR, regardless of sex and age over six, showed moderate agreement with BMI and %BF different from the CI; thus, it can be an option for use in studies in which the aim is to evaluate adiposity and the risk of cardiometabolic diseases.

Background Mixed Martial Arts (MMA) athletes from the Ultimate Fighting Championship (UFC) and Bellator undergo rapid weight regain (RWRG) practices between the official weigh-in and fight night. These athletes are categorized into weight classes and participate in similar weight-cutting regimens. While there have been correlational studies regarding anthropometric measurements and physiological profiles, little research has investigated the relationship between anthropometric measurements and RWRG. Therefore, this study examines the relationships of RWRG variables in professional MMA fighters between the official weigh-in and fight night.Methods Data from 245 professional MMA fighters (30.2 ± 4.6 years, 175.4 ± 8.4 cm) competing between 2018 and 2023 were utilized for this study. Fighters had 24–36 hours to rehydrate between the official weigh-in and fight night. Weigh-ins were supervised under the California State Athletic Commission (CSAC) using a commission-calibrated scale. Pearson correlation analyses were utilized to examine the relationships between age, anthropometric variables, and percentage of RWRG. Statistical significance was set at p ≤ 0.05.Results Pearson correlation analyses revealed significant relationships among age, anthropometric variables, and percentage weight change. Height was strongly and positively correlated with both weight (r = 0.800, p < 0.001) and fight weight (r = 0.795, p < 0.001). A weak but significant negative correlation was found between height and percentage weight change (r = -0.127, p = 0.047). Body weight showed a strong positive correlation with fight weight (r = 0.976, p < 0.001) and a weak negative correlation with percentage weight change (r = -0.249, p < 0.001). No other significant relationships were observed (p ≥ 0.05).Conclusion There are significant correlations between anthropometric variables and RWRG in MMA fighters. The results indicate that taller fighters generally weigh more and compete in heavier weight classes. These findings contribute to the existing literature on correlations between RWRG, height, and weight in MMA athletes. Future research could examine whether RWRG practices differ based on these observed relationships.

This study investigates the effects of coach encouragement (CE) on the physical and technical performance of young tennis players. Twenty nationally ranked male tennis players (age: 13.6 ± 0.3 years, height: 160.9 ± 7.9 cm, body mass: 52.5 ± 7.6 kg,) participated in the present study. The physical and technical tests were conducted both with and without CE, using a randomized crossover design. Participants attended two sessions for performance assessments, undergoing a series of tests, including the hit and turn tennis test (HTTT), international tennis number test (ITN), counter-movement jump (CMJ) test, 20-m sprint tests, and the T-drill agility test. A paired t-test results demonstrated significant improvements in VO2max, CMJ height, 20-m sprint times, T-drill agility, and ITN scores under CE conditions compared to tests conducted without CE (p &lt; 0.05). These findings suggest that CE positively influences physical and technical performances. Moreover, the effects of CE were more pronounced in long-duration exercises (HTTT and ITN), highlighting the crucial role of motivational support from coaches in the development of young athletes.

Introduction and purpose: Low back pain (LBP) is a leading cause of impairment worldwide and its occurrence is still growing. There are many modifiable risk factors contributing to developing LBP, especially obesity, smoking and physical work. In spite of a breakthrough in pharmacotherapy, lifestyle changes and exercise remain the primary prophylactic and treatment options. The aim of this paper was to summarize the data available in the literature and recent reports about the effect of obesity and overweight on LBP and the effectiveness of different exercise programs. Material and methods: The literature was reviewed in the PubMed database, GoogleScholar and the Embase database with the use of keywords. State of knowledge: Obesity and overweight measured by BMI and other indicators are associated with LBP. Waist circumference (WC), recommended by WHO to measure central obesity was found to increase the risk of chronic LBP by 30%, but a stronger correlation between obesity and LBP was found among the female population. Furthermore, there is low-to-moderate evidence that exercise therapy is superior to conservative treatment, when it comes to decreasing pain severity in low back pain. All in all, aerobic, Pilates, core strengthening and stabilization and flexibility exercises were effective in reducing pain with no significant differences between the particular types of training. Summary: The information gathered indicates that obesity and overweight are essential risk factors for LBP. Also, various forms of exercise therapy help patients decrease pain in chronic LBP, however, they should be prescribed individually including preference and fitness level to promote compliance.

Follow-up is the basis for the effectiveness of secondary cardiovascular prevention. Preferential drug provision is a necessary conditionfor the mass implementation of cardiac rehabilitation programs, as it ensures maximum adherence of patients to expensive drugtherapy and the need for regular doctor’s appointment. The Omsk Region has organized and operates a patient routing system aimedat timely initiation and continuous drug provision within the framework of the Federal Project “Fight against Cardiovascular Diseases”.Aim. To evaluate the effectiveness of the first year of cardiac rehabilitation in patients with very high cardiovascular risk who receivedpreferential drugs from the list approved by the Order of the Ministry of Health of the Russian Federation dated January 9, 2020 No. 1n.Material and methods. The study was conducted at the Omsk Region Clinical Cardiology Dispensary, a state-financed health careinstitution, from January 1 to December 31, 2020. A retrospective cohort study was conducted of outpatient records of patientssubjected to preferential provision of medicines, namely, those who were in the dispensary for acute stroke, myocardial infarction, orfor coronary artery bypass grafting, coronary artery stenting or catheter ablation. A clinical-expert analysis of 1502 final clinical reportsof patients who completed follow-up after one year was carried out. The patients’ adherence to dispensary observation, achievementof the target values of the main risk factors, total one-year mortality, frequency of recurrent cardiovascular events and occurrence ofadverse events, primary disability were determined.Results and discussion. Outcomes of follow-up monitoring against the background of subsidized drug coverage: total one-yearmortality – 1.5% (28 patients, 65.9±6.3 years, men 72.7%). Recurrent cardiovascular events in 12 months – 249 (13.8%) patients (68.4±7.4years, men 182 (73.1%)). 10 patients had significant atrial fibrillation paroxysms requiring hospitalization (0.6%, 59.4±5.8 years, 40.0%men). Recurrent cardiovascular events were significantly more common in men (χ2 7.45; p=0.045). Target LDL-C level of less than 1.4mmol/L were achieved in 270 (15.0%) patients with very high cardiovascular risk. Adverse events were identified: non-fatal bleeding –14 patients (0.8%, 73.4±7.6 years, men 57.1%), transaminitis – 14 patients (0.8%, 70.4±2.3 years, men 71.4%), myalgia on statin therapy –21 patients (1.2%, 71.2±2.5 years, men 52.4%), dyspnea on ticagrelor – 21 patients (1.2%, 58.4±4.3 years, men 47.6%) 1432 patients(95.3%) had no specified adverse events. There was a significant increase in new cases of type 2 DM from 331 (18.3%) to 339 (22.6%; χ2McNemar A/D 4.07; p=0.044; B/C 93.09; p=0.002). High-normal blood glucose levels were observed at baseline in 384 patients (21.3%);by the end of follow-up, the number of patients with high-normal glucose was 540 (30.0%; χ2 86.08; p=0.002). There was a significantdecrease in the number of patients with CHF (from 72 (4.0%) to 45 (3.0%); χ2 McNemar A/D 48.52; p=0.000; B/C 45.14; p=0.034).Conclusion. The results obtained testify to the effectiveness of the ongoing comprehensive program of medical rehabilitation(medication, physical rehabilitation and psychological counseling).

Abstract Background Various neurocognitive tests have shown that cycling enhances cognitive performance compared to resting. Event-related potentials (ERPs) elicited by an oddball or flanker task have clarified the impact of dual-task cycling on perception and attention. In this study, we investigate the effect of cycling on cognitive recruitment during tasks that involve not only stimulus identification but also semantic processing and memory retention. Methods We recruited 24 healthy young adults (12 males, 12 females; mean age = 22.71, SD = 1.97 years) to perform three neurocognitive tasks (namely color-word matching, arithmetic calculation, and spatial working memory) at rest and while cycling, employing a within-subject design with rest/cycling counterbalancing. Results The reaction time on the spatial working memory task was faster while cycling than at rest at a level approaching statistical significance. The commission error percentage on the color–word matching task was significantly lower at rest than while cycling. Dual-task cycling while responding to neurocognitive tests elicited the following results: (a) a greater ERP P1 amplitude, delayed P3a latency, less negative N4, and less positivity in the late slow wave (LSW) during color-word matching; (b) a greater P1 amplitude during memory encoding and smaller posterior negativity during memory retention on the spatial working memory task; and (c) a smaller P3 amplitude, followed by a more negative N4 and less LSW positivity during arithmetic calculation. Conclusion The encoding of color-word and spatial information while cycling may have resulted in compensatory visual processing and attention allocation to cope with the additional cycling task load. The dual-task cycling and cognitive performance reduced the demands of semantic processing for color-word matching and the cognitive load associated with temporarily suspending spatial information. While dual-tasking may have required enhanced semantic processing to initiate mental arithmetic, a compensatory decrement was noted during arithmetic calculation. These significant neurocognitive findings demonstrate the effect of cycling on semantic-demand and memory retention-demand tasks.

Purpose of Review The exponential growth of women participating in competitive sports throughout the years was made possible through several initiatives by the International Olympic Committee and the passage and implementation of Title IX as a federal law in the United States. However, this positive trend towards gender equity in sports has not transpired for women in medicine, especially in fields that care for elite athletes. This current review will discuss specific areas that can be tailored to help female athletes prevent injuries and optimize their athletic performance. We will also highlight how increased female team physician representation in sports may help optimize care for female athletes. Recent Findings Female athletes are considered high risk for certain conditions such as ACL tears, patellofemoral pain syndrome, bone stress injuries, sport-related concussions, and sexual violence in sport. Addressing factors specific to female athletes has been found to be valuable in preventing injuries. Strength and conditioning can optimize athletic performance but remains underutilized among female athletes. Although diversity in healthcare workforce has been found to be beneficial for multiple reasons, women remain underrepresented in sports medicine. Increasing female team physician representation may positively impact care for female athletes. Summary Team physicians must understand the physiologic, biomechanical, and anatomic factors that are unique to female athletes in order to tailor injury prevention programs and optimize their athletic performance. Advocating for gender equity in sports medicine to advance representation of women in the field will increase workforce diversity and promote excellence in sports medicine care.

# Background The 11+ program prevents anterior cruciate ligament (ACL) injuries in athletes through unknown mechanisms. # Purpose The aim of the current study was to evaluate the effects of The 11+ intervention program, performed by female soccer players during a single season, on the frequency of Early Peaks during athletic tasks. # Methods Three teams (69 players) of collegiate female soccer athletes (Divisions I and II) were recruited. Two teams (49 players) volunteered to perform The 11+ three times per week for one season (~22 weeks plus three weeks pre-season), and one team (20 players) served as controls. The athletes performed three repetitions of a cutting maneuver, side shuffle direction change, and forwards to backwards running direction change before and after the competitive season and were recorded using marker-based 3D motion capture. Knee valgus moment time series were calculated for each repetition with inverse kinematics and classified as either “Very Early Peak”, “Early Peak” or “other” using cluster analysis. The classification was based timing of the peak relative to the timing of ACL injuries. The effect of the intervention on the frequency of Very Early Peaks and Early Peaks was evaluated with a mixed Poisson regression controlling for the movement task and pre-season frequency. # Results The 11+ intervention reduced the frequency of Early Peak knee valgus moment in one intervention team (coefficient = -1.16, p = 0.004), but not the other (coefficient = -0.01, p = 0.977). No effect was observed on the frequency of Very Early Peak knee valgus moment. # Conclusions Reduced frequency of knee valgus moment Early Peak during athletic tasks may explain the mechanism by which The 11+ program decreases risk of ACL injury. Prospective studies with a much larger sample size are required to establish a link between Early Peak knee valgus moments and risk of ACL injury. # Level of evidence 2b

Introduction: Forward head posture (FHP) is one of the most common types of poor head posture in the sagittal plane. The widespread use of computers, smartphones, and tablets can be one of the causes of poor posture in children and adolescents. The aim of the present study was to assess the position of the head in children and adolescents. Material and Methods: Sixty-two children from a primary school in Krakow were divided into two age groups. Group 1 consisted of 35 children aged 9-11 years, whereas Group 2 included 27 adolescents aged 12-15 years. The photogrammetry method was used to measure head position. The study participants were asked to assess their head and neck position as correct or incorrect. Results: Among all respondents, 16 people (25.81%) had a craniovertebral angle (CVA) in the standing position of fewer than 48 degrees, which indicates a problem with the forward head position. There were statistically significant differences in forward head shift (FHS) and CVA determined in sitting and standing positions between age groups. Group 2 had statistically significantly lower CVA and higher FHS values than Group 1. Fifty-eight (93.5%) study participants considered the positioning of their head and neck to be correct. Conclusions: FHP can occur in children and adolescents.

This review outlines a three-point framework for sports medicine providers, trainers, and coaches to provide a holistic approach for the care of the esports athlete. Abstract Electronic sports (esports), or competitive video gaming, is a rapidly growing industry and phenomenon. While around 90% of American children play video games recreationally, the average professional esports athlete spends 5.5 to 10 h gaming daily. These times and efforts parallel those of traditional sports activities where individuals can participate at the casual to the professional level with the respective time commitments. Given the rapid growth in esports, greater emphasis has been placed on identification, management, and prevention of common health hazards that are associated with esports participation while also focusing on the importance of health promotion for this group of athletes. This review outlines a three-point framework for sports medicine providers, trainers, and coaches to provide a holistic approach for the care of the esports athlete. This esports framework includes awareness and management of common musculoskeletal and health hazards, opportunities for health promotion, and recommendations for performance optimization.

Medical and sports medicine associations are reluctant to endorse isometric exercise to the same extent as dynamic resistance exercise (RE). The major concern is the fear of greater increases in blood pressure (BP) that might be associated with isometric exercise. This review comprehensively presents all human studies that directly compared the magnitude of hemodynamic responses between isometric and dynamic RE. We also discuss possible mechanisms controlling BP-response and cardiovascular adjustments during both types of RE. The most prominent finding was that isometric and dynamic RE using small-muscle mass evoke equal increases in BP; however, the circulatory adjustments contributing to this response are different in dynamic and isometric RE. In contrast, studies using large-muscle mass report inconsistent results for the magnitude of BP-response between the two types of RE. Thus, when the same muscles and workloads are used, the increase in BP during isometric and dynamic RE is more comparable to what is commonly believed. However, it should be noted that only a few studies equalized the workload in two types of RE, most used small sample sizes, and all studies employed healthy participants. More studies are needed to compare the cardiovascular risks associated with isometric and dynamic RE, especially in individuals with chronic disease.

Study objective: to establish the correlation between the paretic hand movement recovery in post-stroke patients in the stroke late residual period and the patients’ somatotypes.Materials and methods. The study involved 91 people in the second period of adulthood (53 men, 38 women), somatotyping was performed according to the W.L. Rees — H. Eysenck method. Results. Statistically significant differences in the upper paretic limb movement range recovery were found in men and women in accordance with the body type. Conclusions. The highest percentage of normal movement range was recorded in the limbs’ proximal joints of the (shoulder) during movements around the frontal and sagittal axes. The volume of rotational movements as a percentage of the norm was less by 13–17%. The men demonstrated maximum movement recovery of shoulder extension, and this tendency is typical for mature men of asthenic and pyknic somatotypes. The women in all the examined groups demonstrated the minimal increase in the movement ranges in the shoulder and elbow joints.

Background Preoperative knee function is associated with successful postoperative outcome after anterior cruciate ligament reconstruction (ACLR). However, there are few longer term studies of patients who underwent progressive preoperative and postoperative rehabilitation compared to usual care. Objectives To compare preoperative and 2 year postoperative patient-reported outcomes (PROs) in patients undergoing progressive preoperative and postoperative rehabilitation at a sports medicine clinic compared with usual care. Methods We included patients aged 16–40 years undergoing primary unilateral ACLR. The preoperative and 2 year postoperative Knee Injury and Osteoarthritis Outcome Score (KOOS) of 84 patients undergoing progressive preoperative and postoperative rehabilitation at a sports medicine clinic (Norwegian Research Center for Active Rehabilitation (NAR) cohort) were compared with the scores of 2690 patients from the Norwegian National Knee Ligament Registry (NKLR). The analyses were adjusted for sex, age, months from injury to surgery and cartilage/meniscus injury at ACLR. Results The NAR cohort had significantly better preoperative KOOS in all subscales, with clinically relevant differences (>10 points) observed in KOOS Pain, activities of daily living (ADL), Sports and Quality of Life. At 2 years, the NAR cohort still had significantly better KOOS with clinically relevant differences in KOOS Symptoms, Sports and Quality of Life. At 2 years, 85.7–94% of the patients in the NAR cohort scored within the normative range of the different KOOS subscales, compared to 51.4–75.8% of the patients in the NKLR. Conclusions Patients in a prospective cohort who underwent progressive preoperative and postoperative rehabilitation at a sports medicine clinic showed superior patient-reported outcomes both preoperatively and 2 years postoperatively compared to patients in the NKLR who received usual care.
