China has formally established a 220-member delegation for the 48th WorldSkills Competition to be held in Shanghai from September 22 to 27, with the approval of the Ministry of Human Resources and Social Security.
The delegation includes 71 competitors, 64 experts, and 64 interpreters and staff members. The competitors will take part in all 64 skill competitions at the event, the Science and Technology Daily reported. 
The 71 competitors come from 21 provincial-level regions across China, including 49 students and 22 employees. Their average age is 21, with the youngest aged 18 and the oldest 25.
The WorldSkills Competition is the world's biggest international skills competition, bringing together young people, industry, education and government leaders from around the world to advance Technical and Vocational Education and Training, according to the WorldSkills Shanghai 2026 website.
About 1,400 competitors from nearly 70 countries and regions are expected to compete across 64 official skill competitions.
WorldSkills Conference 2026 and the WorldSkills Shanghai 2026 Expo will be held alongside the Competition, according to the event's official website.
Since joining WorldSkills International in October 2010, China has participated in seven editions of the WorldSkills Competition, winning 93 gold medals, 41 silver medals, 28 bronze medals and 71 Medallions for Excellence, according to Science and Technology Daily.
China has ranked first in both the gold medal table and overall team points for four consecutive editions. The Shanghai event will mark the country's eighth participation and the third time it has entered every skill competition.
"The delegation will strictly observe competition rules, compete fairly and with civility, demonstrate both sportsmanship and skill, and fully showcase the superb expertise and positive image of China's young skilled professionals in the new era," an official with the Chinese delegation was quoted as saying by Science and Technology Daily.
China's award ceremony uniforms and competition uniforms have also been unveiled. Both sets draw their central design elements from traditional Chinese mortise-and-tenon joinery, highlighting the inheritance of craftsmanship and the cultural confidence of China's young skilled professionals, according to the Xinhua News Agency.

。    每年的10月20日是世界骨质疏松日，2024年世界骨质疏松日的中国主题为“管体重、强骨骼”，倡议社会各界传播科学管理体重、强健骨骼的理念，以预防骨质疏松症和脆性骨折的发生。         　　01、体重与骨骼健康的关系          　　体重是影响人体代谢和骨骼健康的重要因素，在生命的各个阶段都会影响骨骼健康。低体重是骨质疏松和脆性骨折的重要危险因素。人体在健康体重或体重适度增加时，体重与骨密度呈正相关。但体内脂肪含量过高时会导致骨转换失衡，使成骨细胞活性减低，破骨细胞活性增加，从而导致骨丢失加快，增加骨质疏松风险。         　　在日常生活中如何同时做好体重管理和骨质疏松的预防呢？          　　这个问题并不难，答案就是积极践行健康生活方式！          　　02、践行健康生活方式 预防骨质疏松          　　1做好体重管理          　　合理饮食          　　保持均衡膳食，确保摄入足够的营养成分，避免过度摄入高热量、高脂肪、高糖的食物。对于低体重者，可适当增加能量摄入，包括富含优质蛋白质、碳水化合物的食物；对于超重和肥胖者，则要控制热量摄入。注意控制食物的份量，避免暴饮暴食。         　　保证身体活动          　　选择适合自己身体状况的运动方式，如散步、慢跑、游泳、瑜伽等。

二 | 坚持规律运动，每周至少进行150分钟的中等强度有氧运动，也可结合力量训练，如举哑铃、俯卧撑等，增加肌肉量，提高基础代谢率，助力体重管理。         　　定期监测          　　定期测量体重、腰围、体脂率等，了解体重变化趋势和身体脂肪、肌肉等成分的比例。

三 | 根据监测结果调整饮食和运动计划，确保体重管理的有效性和健康性。         　　2确保营养摄入          　　钙和维生素D是维持骨骼健康的重要元素，老年骨质疏松症患者普遍存在钙与维生素D不足或缺乏。钙的来源包括食物如奶类及其制品、大豆类及其制品、水产类、坚果、深绿色蔬菜等，也可根据医生建议适当补充钙剂。         　　《中国居民膳食指南（2022）》建议老年人（＞65岁）每日钙的摄入量为1000mg。《原发性骨质疏松症诊疗指南（2022）》建议50岁以上中老年人每日元素钙摄入量为1000~1200mg。然而，中国人群日常饮食中的钙含量通常偏低，《中国老年骨质疏松症诊疗指南（2023）》建议老年骨质疏松症患者可通过饮用牛奶或补充钙剂来增加钙摄入量，使钙总摄入量达800~1200mg/d。         　　除了食物和药物补充，多晒太阳可促进皮肤内生维生素D的形成，进而促进肠道内的钙吸收。此外，蛋白质是骨骼生长和修复的重要原料，优质蛋白质来源包括奶、蛋、禽类以及其他肉类。         　　03、重视肌肉力量和平衡能力练习          　　通过合理的营养和增强抗阻、力量锻炼可以促进骨骼强健，与体重或体质指数相比，肌肉量与骨密度的相关性更强。国际骨质疏松基金会发布的最新信息显示，对骨骼健康最有益的运动类型是负重运动和力量训练，比如举、推、跑、跳以及“登台阶”等方式，可使骨骼更加强健。         　　平衡能力锻炼对于关节健康以及避免运动受伤有重要作用，是一种锻炼身体平衡能力的运动，由视觉监督练习逐渐过渡到闭目练习。推荐的动作包括单腿站立、平衡垫双脚站立、平衡垫单脚站立等。平衡能力练习对于老年人预防跌倒防骨折尤其重要。

四 |          　　骨骼健康问题不是老年人的专利，每个年龄段人群都要“强肌健骨增力量”，保持骨骼健康！          　　最后，大家可以一起回顾下全民健康生活方式行动推出的健康骨骼核心信息，强化理解~          　　营养、运动、晒太阳，有利于促进或保持骨量；          　　科学运动防损伤，爱护全身骨骼和关节，保持持续行动力；          　　儿童青少年端正身姿和体态，少久坐多锻炼；          　　40岁以上人群应检测和了解自身骨密度，预防骨质疏松症；          　　老年人应重视力量和平衡能力练习，预防跌倒防骨折。                    责任编辑：李丹。
