In refractory cases to conservative treatment, microscopic discectomy or full endoscopic discectomy are used as surgical options to relieve pain and restore patient functionality. However, the ideal time for a return to sports activities remains a matter of debate due to variations in recovery times and risks of complications associated with each technique. Methods: A review was conducted, including articles published in the last 33 years (1991-2024), as it was the earliest date matching our search criteria. Clinical studies, systematic reviews, meta-analyses, and clinical guidelines were included. Results: The most common complications when returning to sport prematurely include recurrence of the hernia, persistent pain (VAS leg 7 or higher after surgery) and reduced physical performance. The return to full activity rate of patients who underwent microdiscectomy reaches up to 90%, while the endoscopic technique shows a success rate that reaches 99%. Return to play meantime was 5.19 months (range 1.00 - 8.7 months) and mean time of 4.6 months (range 2 - 8 months) with Microdiscectomy and full endoscopic discectomy respectively. Conclusions: There is no unanimous consensus on the exact timing of return to sport due to variability in recovery times and clinical outcomes. In both techniques, evidence highlights the need for a multidisciplinary approach that integrates surgeons, physical therapists and trainers to optimize recovery and ensure a safe return.展开更多

文摘Objectives:In this study,we examined the psychological impact of hierarchical and authoritarian structures in elite sports teams in South Korea on the ego formation and mental health of athletes.We aimed to analyze how these environments shape psychological well-being in athletes,drawing on Freud’s group psychology theory,while integrating perspectives from the Self-DeterminationTheory(SDT)and Social Identity Theory(SIT).Methods:We applied a qualitative case-study approach,with data collected through in-depth interviews with eight retired elite table tennis players from South Korea.These athletes shared their experiences with psychological mechanisms in their teams and how those mechanisms impacted their mental health throughout their careers.We analyzed the collected data using thematic analysis.Results:The investigated psychological mechanisms significantly influenced the ego development and psychological well-being in athletes.In hierarchical and authoritarian environments,identification and ego idealization suppressed the autonomy of the athletes.Hierarchical order and obedience to authority figures exert significant pressure on athletes to conform,impeding the development of an independent ego.Furthermore,group pressure exacerbates ego erosion and psychological stress,while corporal punishment reinforces psychological pressure and hinders ego integrity.The integration of the SDT highlights the need for autonomy-supportive environments to mitigate such risks,while the SIT emphasizes balancing individual identity with group cohesion to address identity conflicts and psychological tension.Conclusion:Hierarchical structures and authoritarian dynamics in South Korean elite sports teams critically suppress autonomy in athletes,leading to psychological distress and identity conflicts.This study highlights the urgent need for systemic interventions to reform coaching practices and foster autonomysupportive environments.These results contribute to the global discourse on the mental health of athletes in elite sports and offer actionable strategies for improving long-term well-being.Finally,this study provides practical recommendations adaptable to diverse cultural and sporting contexts,enhancing athlete mental health worldwide.
文摘The balance of urban and rural public sports services directly affects residents'quality of life and social equity,but traditional evaluation methods rely on manual research and statistical models,which have problems such as low efficiency,single indicators,and insufficient dynamic response capabilities.This study proposes an AI based framework for evaluating the balance of urban and rural public sports services(AI-PSBE),which integrates multi-source heterogeneous data(satellite images,policy texts,user behavior logs)with multimodal deep learning techniques to achieve dynamic evaluation of multidimensional indicators such as coverage,quality,and usage efficiency.This framework uses ResNet-50 and Transformer dual channel architecture to extract spatial and semantic features,and generates a balance index through an adaptive weight fusion module.Based on urban and rural data from 10 provinces in China,experiments have shown that the evaluation accuracy of AI-PSBE(R^(2)=0.937)has improved by 41.2%compared to traditional methods,with a response time reduced to 3 minutes.Additionally,the interpretability heatmap intuitively displays regional shortcomings.This study provides intelligent tools for optimizing the layout of public sports resources.

文摘Genetic variation contributes to the phenotypic diversity of plants.Most red pear cultivars that accumulate anthocyanins originated from somatic variation and are termed as bud sports.‘Hongzaosu’is a bud sport derived from the green pear‘Zaosu’.A new genetic map was constructed from a population derived from the cross of‘Yuluxiang’and‘Hongzaosu’,from which PpBBX24 was identified as a crucial gene controlling anthocyanin accumulation.Genetic and phylogenetic evidences revealed that PpBBX24 is a repressor of anthocyanin biosynthesis in pear.A 14 bp deletion was detected in the third exon of PpBBX24 in‘Hongzaosu’,resulting in premature termination of protein translation.The truncated PpBBX24 protein was a positive regulator of anthocyanin biosynthesis by activating the transcription of PpCHS and PpUFGT.Three independent variations in the BBX24 coding region that led to premature termination of translation were detected in other pear bud sports and the progeny of a bud sport that all accumulate anthocyanins.The genome of‘Hongzaosu’was assembled using both long-read and short-read sequences.By combining genomic and transcriptomic data,allele-specific expression of PpMYB110a was observed in the fruit skin of‘Hongzaosu',which was likely caused by a large variation in the promoter.This work enhances understanding of coloration in red pears and provides a novel genomic resource for further studies on‘Hongzaosu’pear.
文摘Background:Sports medicine(injury and illnesses)requires distinct coding systems because the International Classification of Diseases is insuf-ficient for sports medicine coding.The Orchard Sports Injury and Illness Classification System(OSIICS)is one of two sports medicine coding systems recommended by the International Olympic Committee.Regular updates of coding systems are required.Methods:For Version 15,updates for mental health conditions in athletes,sports cardiology,concussion sub-types,infectious diseases,and skin and eye conditions were considered particularly important.Results:Recommended codes were added from a recent International Olympic Committee consensus statement on mental health conditions in athletes.Two landmark sports cardiology papers were used to update a more comprehensive list of sports cardiology codes.Rugby union protocols on head injury assessment were used to create additional concussion codes.Conclusion:It is planned that OSIICS Version 15 will be translated into multiple new languages in a timely fashion to facilitate international accessibility.The large number of recently published sport-specific and discipline-specific consensus statements on athlete surveillance warrant regular updating of OSIICS.
