Core Insights - The article emphasizes the importance of joint health, highlighting that many individuals overlook it despite the significant pressures joints endure during physical activities. For instance, the pressure on the knee joint during running can be four times a person's body weight, and during squats, it can reach eight times [1][3]. Group 1: Market Opportunities - The sports rehabilitation sector is rapidly identifying business opportunities, with products like pain relief massage chairs and joint care courses being introduced in gyms. For example, the brand Jianliduo, focused on bone health, achieved a revenue increase from 100 million to 1 billion in five years [2]. - In 2020, the average monthly sales of joint massage devices on Taobao reached 23.18 million, with a significant focus on knee joint products [2]. Group 2: Exercise and Joint Health - Active exercise is shown to have a greater positive impact on joint health than passive treatments. Proper exercise can maintain bone strength and muscle around joints, countering issues like pain and stiffness often linked to inactivity. Notably, losing one pound can reduce knee joint pressure by four pounds and hip joint pressure by six pounds [3]. - Low-impact exercises are crucial for protecting joints. For instance, weightlifting and tennis players use elbow braces to mitigate high-impact stress on their joints [5]. Group 3: Lifestyle Factors - Joint health maintenance is not solely about exercise; lifestyle habits play a significant role. Prolonged sitting can lead to insufficient synovial fluid in joints, while standing too long can increase spinal and joint stress. Proper sitting, standing, and lying positions are essential for joint health [7]. - Joint issues are increasingly affecting younger populations, with 7.1% of individuals aged 18-44 diagnosed with some form of arthritis [8]. Group 4: Treatment and Prevention - The treatment industry for joint health is evolving, with advancements like PRP (platelet-rich plasma) injections showing effectiveness in treating knee osteoarthritis, particularly among younger individuals [13][16]. - Preventive measures should be prioritized, including controlling exercise intensity, warming up before activities, and selecting appropriate footwear to reduce joint impact [25]. Group 5: Nutrition and Joint Health - Diet and nutrition significantly influence joint health. Processed oils and refined carbohydrates can increase inflammation risks [26]. - Foods rich in flavonoids, such as blueberries, and those containing anti-inflammatory properties, like pineapple and tomatoes, can help mitigate joint inflammation [27].
