However, free weight exercises, including squats, can, in fact, have positive improvements on those suffering from joint-degrading diseases such as rheumatoid arthritis (RA ) and osteoarthritis (OA). People suffering from rheumatoid arthritis have chronic inflammation of the joints, while wear and tear on the ligaments causes osteoarthritis. A two-year randomized trial documented the effects of strength training on muscle strength, disease activity, functional capacity, and bone mineral density in early rheumatoid arthritis. The study found that strength training improved muscle strength, physical ability, bone mineral density and joint function by 19% to 59% (Häkkinen). Another study conducted on OA similar to the one on rheumatoid arthritis produced similar results: “exercise is a vital component of treatment for some of the mechanisms underlying knee OA” (Vincent). Strength training has no detrimental effect on joint health and function and can improve the joints of those suffering from joint pain due to rheumatoid arthritis and osteoarthritis, completely disproving the idea that strength training damage your joints. While those suffering from poor joint health may refrain from strength training due to unfounded health and safety concerns, others refuse for more superficial reasons. Many women choose not to strength train or lift weights because they fear becoming "too bulky" or "manly." look." The appearance of female bodybuilders typically provokes this fear as they, like male bodybuilders, strive to have muscular and virtually fat-free bodies. However, the hormonal profile of natural women prevents them from having the same musculature and strength as men. men The male sex hormone, testosterone, has anabolic properties (increased muscle/strength… middle of paper… which Strength training has been shown to increase strength and joint function and is. a safe and feasible physical activity for women and children, there are very few individuals, if any, who would not benefit from strength training. Benefits range from increased muscle size and strength, increased bone mineral density, increased of the cardiovascular system, increased self-esteem, improved self-image, increased confidence and even increased libido. Weightlifting has one of the lowest injury rates compared to other major physical activities, which means people can exercise safely low risk and high reward. With the increasingly sedentary but fast-paced lifestyle that most people live, they now have to make an effort to stay healthy. As a result, everyone should use strength to have an optimal time and cost-effective way to improve overall health and physical function.
