Physical activity can provide health benefits if done regularly and of sufficient duration and intensity. The World Health Organization recommends adults do 150-300 min of moderate-intensity activity per week, 75-150 min of vigorous-intensity activity, or an equivalent combination.Physical inactivity is the fourth leading cause of early death globally, with 31% of the world's population not getting enough physical activity. Aging is defined by rapid decline in physical activity, loss of mobility, and premature morbidity.Low testosterone levels in men decline from 30 to 40 years of age, and this continues until death. Antiaging strategies, such as caloric restriction, balanced diet, regular exercise, weight management, diabetes control, and smoking cessation can prevent and treat aging-related diseases. Exercise significantly boosts testosterone production, with levels varying based on type, frequency, volume, intensity, and duration. It increases muscle steroidogenesis, total testosterone, and free testosterone in the elderly. Testosterone replacement therapy in elderly men improves physical function, strength, protein synthesis, cholesterol, bone density, sexual desire, erectile function, and overall cognition. However, some studies suggest dehydroepiandrosterone supplementation may provide health improvements without negative effects, potentially reversing arterial aging and reducing the risk of cardiovascular diseases. Senolytic therapeutics focus on cellular senescence, and stem cell transplantation investigates the therapeutic potential of older stem cells.
如果有规律地进行且持续时间和强度足够,体育活动对健康有益。世界卫生组织建议成年人每周进行150 - 300分钟的中等强度活动、75 - 150分钟的高强度活动,或同等的组合。缺乏体育活动是全球过早死亡的第四大主要原因,世界上31%的人口没有进行足够的体育活动。衰老的定义是身体活动迅速下降、行动能力丧失和过早发病。男性的睾酮水平在30到40岁之间开始下降,并一直持续到死亡。抗衰老策略,如热量限制、均衡饮食、定期锻炼、体重管理、糖尿病控制和戒烟,可以预防和治疗与衰老相关的疾病。运动能显著提高睾酮的分泌,其水平会因运动类型、频率、量、强度和持续时间而有所不同。运动能增加老年人肌肉中的类固醇生成、总睾酮和游离睾酮。老年男性的睾酮替代疗法可改善身体功能、力量、蛋白质合成、胆固醇水平、骨密度、性欲、勃起功能和整体认知能力。然而,一些研究表明补充脱氢表雄酮可能在无负面影响的情况下改善健康,有可能逆转动脉衰老并降低心血管疾病风险。衰老细胞溶解疗法关注细胞衰老,而干细胞移植则研究老年干细胞的治疗潜力。
