Physical activity (PA) is one of the most important factors to determine health outcomes. It is well established that for many musculoskeletal problems, PA and exercise are the way to better health. PA offers a wide range of physical and psychological benefits which may vary based on intensity, frequency and activity type. Most of the international guidelines recommend that an adult takes part in at least 150 min/week of moderate-intensity PA.1 PA as defined by the WHO is any bodily movement produced by skeletal muscles that requires energy expenditure. Leisure-time physical activity (LTPA) is a term used to describe the activity persons do in their free time. Occupational physical activity (OPA) is the type of activity that is associated with a job and is usually within the timeframe of how long a person works, such as an 8-hour work shift. One would think that if a person is active 8 hours a day at the job (ie, farming, cleaning, doing construction work, elderly care, etc), then that person should be in good condition health-wise. But what does the evidence say? Many systematic reviews and randomised controlled trials report that OPA increases the risk for all-cause mortality, cardiovascular diseases (CVDs), overuse injuries and some carcinomas.2–5 Holtermann et al showed that high OPA increases the risk for all-cause mortality among male workers. Among …

“我的工作足够积极。” 为什么职业体育锻炼不够？

身体活动 (PA) 是决定健康结果的最重要因素之一。众所周知，对于许多肌肉骨骼问题，PA 和锻炼是改善健康的方法。PA 提供广泛的身体和心理益处，这些益处可能因强度、频率和活动类型而异。大多数国际指南建议成年人每周至少参加 150 分钟的中等强度 PA。1 WHO 定义的 PA 是由骨骼肌产生的任何需要能量消耗的身体运动。休闲时间身体活动 (LTPA) 是用于描述人们在空闲时间进行的活动的术语。职业体育活动 (OPA) 是与工作相关的活动类型，通常在一个人工作多长时间的时间范围内，例如 8 小时轮班制。有人会认为，如果一个人每天工作 8 小时（即农业、清洁、建筑工作、老人护理等），那么这个人的健康状况应该很好。但是证据说明了什么？许多系统评价和随机对照试验报告说，OPA 会增加全因死亡率、心血管疾病 (CVD)、过度使用损伤和某些癌症的风险。 2-5 Holtermann 等人表明，高 OPA 会增加全因死亡率的风险。男工。之中 … 但是证据说明了什么？许多系统评价和随机对照试验报告说，OPA 会增加全因死亡率、心血管疾病 (CVD)、过度使用损伤和某些癌症的风险。 2-5 Holtermann 等人表明，高 OPA 会增加全因死亡率的风险。男工。之中 … 但是证据说明了什么？许多系统评价和随机对照试验报告说，OPA 会增加全因死亡率、心血管疾病 (CVD)、过度使用损伤和某些癌症的风险。 2-5 Holtermann 等人表明，高 OPA 会增加全因死亡率的风险。男工。之中 …
