Objective: Recruits were instructed on corrective training based on the results of the Evaluation of Military Physical Function (EMPF) and evaluated for motor performance enhancement and training injury prevention effects. Methods: An EMPF test was conducted on 339 new recruits, who were randomly divided into an intervention group and a control group. The control group continued to implement the original training plan, while those with abnormal EMPF results in the intervention group additionally conducted corrective exercise for 8 weeks. After 8 weeks, another EMPF was conducted to evaluate the incidence of training injuries and training performance in both groups. Results: After 8 weeks, the total score of EMPF in the intervention group was significantly higher than that in the control group (P<0.05). Additionally, the intervention group showed significantly improved performance in the snake run and pull-up compared to the control group (P<0.01). The incidence of training injuries in the intervention group (6.87%) was significantly lower than that in the control group (14.90%) (P<0.05). Conclusion: The EMPF scale can be used to assess the risk of sports injury. Corrective training interventions can be implemented for individuals with abnormal EMPF results, which can effectively improve the athletic ability of officers and soldiers, improve weak links in movement patterns, and reduce the risk of sports injury.

The aim of this study was to investigate the rehabilitation strategies of chronic ankle instability (CAI), focusing on analyzing the effects of strength training combined with other exercise therapies on the rehabilitation effects of CAI patients. Through searching the relevant literature at home and abroad, this study comprehensively analyzed the studies on the intervention of strength training combined with other exercise therapies on CAI patients and evaluated the muscle activation, muscle strength, postural stability, and ankle instability symptoms. It was found that strength training combined with other exercise therapies performed better in shortening peroneal muscle reaction time, enhancing muscle strength, improving dynamic and static postural stability, and improving self-perceived ankle instability in patients with CAI compared with a single training regimen. There were differences in the improvement effects of different training programs on CAI patients. In conclusion, strength training combined with other exercise therapies can multifacetedly improve muscle activation, muscle strength and postural stability in CAI patients, thus enhancing neuromuscular control function, and then effectively alleviate the instability symptoms and improve the quality of life of CAI patients.

Objective: To investigate the effect of “sequential fracture reduction” in the conservative treatment of distal radius fractures in the elderly. Methods: 68 cases of distal radius fracture in our department were selected. Patients were selected from January 2022 to March 2024, and were individed by numerical table method. The control group (n = 34) was treated with conventional reduction and plaster fixation. The study group (n = 34) combined with the concept of “sequential fracture reduction” in the repair of sports injuries. After 1 year follow-up, the reduction quality, wrist function and complications were evaluated in both groups. Results: The reduction quality score of fracture in study group was lower than that in control group (P<0.05). The Gartland-Werley score of the study group was higher than that of the control group (P<0.05) at the two time points of “clinical fracture healing” and “1 year follow-up”. The complication rate of the study group (5.88%) was lower than that of the control group (26.47%) (P<0.05). Conclusion: The conservative treatment of senile distal radius fractures with the concept of “sequential fracture reduction” has better reduction quality and wrist joint function than conventional treatment, and the incidence of complications is lower.

Objective: To investigate the application value of high frequency musculoskeletal ultrasonography in training injuries of airborne soldiers in outdoor resident training environment. Methods: Retrospective analysis was performed on 40 patients (80 in total, left and right knee) with long-term high-intensity training injuries (taking knee injury as an example) admitted to our hospital from January to December 2023. Musculoskeletal ultrasound (observation group), MRI (control group) and arthroscopy (gold standard) were performed to evaluate the diagnostic value of ultrasound and MRI in knee diseases. Compare their accuracy, detection rate, and inspection time. Results: The accuracy and detection rate of musculoskeletal ultrasound were higher than MRI in synovitis and bursitis, tendinopathy, tendon injury and tear, and the examination time of musculoskeletal ultrasound was shorter than MRI, with statistical significance (P<0.05). The detection rate and accuracy rate of musculoskeletal ultrasound in osteoarthritis was about MRI. The ultrasonic detection rate and accuracy of meniscus injury and ligament injury were lower than those of MRI, and the difference was not statistically significant (P>0.05). Conclusion: Both high-frequency musculoskeletal ultrasound and MRI have high diagnostic value for knee osteoarthropathy, and high-frequency musculoskeletal ultrasound can be used as the first choice of auxiliary diagnostic tools for training injuries in special training environments, providing first-line diagnosis and treatment help for military training injuries.

Objective: To explore the effects of the self-developed sports game “Versatile Tire” (hereinafter referred to as “sports game”) on attention related indicators (attention breadth, attention stability, attention allocation, and attention transfer) in obese children aged 8-10 years old. Methods: Forty obese children aged 8-10 years old from a primary school in Shanghai were randomly divided into an experimental group and a control group, with 20 children in each group. There were no significant differences in age, height, weight, and BMI between the two groups of obese children (P>0.05). A 12 week (3times/w, 35min/time) intervention was conducted using the created sports game “Versatile Tire”. The attention of obese children was evaluated using the “Adolescent Attention Test” scale, and statistical analysis was conducted using SPSS 23.0. The association between sports games and attention was scientifically explained through data analysis. Results: After 12 weeks of sports game intervention, the experimental group showed a significant improvement in attention allocation and attention transfer scores (P<0.05), a very significant improvement in attention stability scores (P<0.01), while there was no significant change in attention breadth scores (P>0.05). The control group showed a significant increase in attentional shift scores (P<0.05), while there was no significant change in attentional allocation, attentional breadth, and attentional stability scores compared to before the baseline of the experiment group the experiment (P>0.05); After intervention, the experimental group showed a significant improvement in attention stability scores compared to the control group (P<0.05), while there were no significant changes in attention allocation, attention breadth, and attention transfer (P>0.05). Conclusion: Sports games are closely related to the attention of obese children aged 8-10, and are crucial for improving their attention levels.

Objective: To investigate the impact of applying an early rehabilitation therapy program on wrist joint function recovery in patients with distal radius fractures. Methods: From May 2022 to October 2023, 98 patients with distal radius fractures were admitted to our hospital,who were randomly divided into the observation group and the control group, with 49 patients in each group. The control group received conventional treatment after surgery, while the observation group underwent early rehabilitation therapy after surgery. The differences in treatment effects between the two groups were compared. Results: （1） The treatment efficiency of the observation group was higher than that of the control group, and the difference was statistically significant (P < 0.05). （2） There were no significant differences in Cooney score, Modified Barthel Index (MBI) score, dorsal extension range of motion, and flexion range of motion between the two groups immediately after surgery (P> 0.05). However, three months after treatment, the observation group showed better improvement in Cooney score, MBI score, dorsal extension range of motion, and flexion range of motion compared to the control group, with statistically significant differences (P < 0.05). Conclusion: The application of early rehabilitation therapy in the treatment of wrist joint function recovery after distal radius fracture surgery can help improve patients' rehabilitation treatment effects and wrist joint function, making it a worthwhile recommendation.

Objective: To compare the clinical efficacy of cement-type extended shank artificial femoral head replacement and Proximal Femoral Nail Antirotation(PFNA) in the treatment of unstable Intertrochanteric Fracture (ITF) in osteoporosis patients over 80 years old. Methods: 64 patients with ITF admitted to our hospital from September 2022 to June 2024 were retrospectively analyzed, divided into joint replacement group and PFNA group, and the surgical indexes and functional scores of the two groups were compared.Logistic regression analysisand ROC curveswere used to analyze the risk factors and evaluate the diagnostic efficacy of postoperative delirium.Results: （1） Surgical indexes: Operation time (92.82± 8.14 min), blood loss (133.18±44.20 ml) and incision length 6.85± 1.12 cm in PFNA group were better than those in joint replacement group (P<0.05). However, weight bearing time (4.27± 0.52 weeks) and latent blood loss (688.59±38.92 ml) in PFNA group were significantly higher than those in joint replacement group (P<0.05). （2） Functional score: The hip Harris score and Barthel ability of daily living score of the joint replacement group were higher than those of the PFNA group at 1, 3 and 6 months after operation (P<0.05), but there was no significant difference between the two groups after 1 year (P>0.05). （3） Complications: The complication rate in the joint replacement group (20%) was significantly lower than that in the PFNA group (44.1%,P<0.05). (4) Delirium risk: Surgical method and occult blood loss were independent risk factors for postoperative delirium, and the area under the curve (AUC) of occult blood loss was 0.817(P<0.05), which had significant diagnostic value. Conclusion: （1） PFNA is predominant in surgical simplicity and trauma, while joint replacement is more advantageous in early functional recovery, reduction of delirium and complications; （2） Recessive blood loss is an important predictor of postoperative delirium, and clinical attention should be paid to it; （3） Joint replacement is an important complementary option for the treatment of unstable ITF in the elderly for patients with severe osteaporosis and need to move to the ground early.

Motion capture is an important method of biomechanics research in sports science. Motion capture could be realized through three methods manual recognition, marker-based and marker-less. The methods of manual recognition is time consuming and subjective. The method of marker-based affects human motion and the test environment is limited, while marker-less motion capture method can effectively solve these problems. Marker-less motion capture originated from computer vision and machine learning, which could estimate human posture from images and videos. The key technologies mainly include contour extraction, pose estimation and tracking. Marker-less motion capture is under development. There are a large number of public datasets for the development of marker-less motion capture. A few marker-less motion capture systems were published, including STAGE, Theia3D, FastMove and so on. Some studies have applied marker-less motion capture to the research of sports science and motion analysis, but the kinematic parameters might not meet the accuracy requirements of sports science. Compared with traditional motion capture methods, marker-less motion capture method is more portable and lower cost. Marker-less motion capture would be widely used in sports science research in the future.

With the intensification of global population aging, the elderly population is facing significant challenges of cerebral vascular function degradation and cognitive decline. Aerobic exercise, as a widely used and low-cost intervention to improve cerebrovascular status, significantly prevents cerebrovascular diseases. This article reviews the mechanism of the effects of aerobic exercise on the cerebral vasculature and cognitive function in elderly individuals, discussing five aspects: hippocampus and anterior cingulate cortex (ACC), cerebral vascular reactivity (CVR), cerebral blood flow (CBF), endothelial cells (EC), and brain-derived neurotrophic factor (BDNF). Research has shown that aerobic exercise can increase cerebral blood flow perfusion in the hippocampus and ACC, improve CVR, increase CBF, and enhance the supply of oxygen and nutrients in the brain, thereby promoting the metabolic activity of nerve cells. Enhance EC function, promote the synthesis and release of BDNF, and improve cognitive performance. Future research needs to explore further the specific mechanisms behind aerobic exercise improving cerebrovascular and cognitive function and investigate the effects of different types, frequencies, intensities, and personalized exercise intervention programs on the elderly population, providing a more solid theoretical basis for aerobic exercise to improve cerebrovascular and cognitive function in the elderly.

Osteoporosis (OP) is a prevalent metabolic bone disease among postmenopausal women, emerging as a major public health concern. Studies indicate that this population is susceptible to hormonal dysregulation, which disrupts bone metabolic balance, reduces bone mineral density, and accelerates osteoporosis progression. This study analyzes postmenopausal hormonal metabolic disorders, demonstrates the significant efficacy of physical activity interventions in osteoporosis prevention and treatment, and proposes early prevention strategies combining exercise with pharmacological approaches. These findings provide valuable clinical references for managing postmenopausal osteoporosis.
