However, free weight exercises, including squats, may actually have positive improvements in people with degrading joint diseases such as rheumatoid arthritis (RA) and osteoarthritis (OA). People who suffer from rheumatoid arthritis have chronic inflammation of the joints, while wear and tear on the ligaments causes osteoarthritis. A two-year randomized study 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 capacity, bone mineral density and joint function by 19% to 59% (Häkkinen). Another study conducted on osteoarthritis, similar to that on RA, produced similar results: “exercise is an essential part of treating some of the underlying mechanisms of knee osteoarthritis” (Vincent). Strength training has no detrimental effects on joint health and function and can improve the joints of people with joint pain from rheumatoid arthritis and osteoarthritis, completely disproving the idea that strength training Strength training damages joints. While those with 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 usually provokes this fear because, like male bodybuilders, they strive to have a muscular and virtually fat-free body. However, the hormonal profile of natural women prevents them from having the same muscularity and strength the same as men The male sex hormone, testosterone, has anabolic properties (increased muscle/strength...... middle of paper...... which has been proven). that strength training increases joint strength and function and is a safe and viable physical activity for women and children. There are very few, if any, individuals who do not. Benefits from strength training range from increased muscle size and strength, increased bone mineral density, increased cardiovascular self-esteem, improved self-image, and increased confidence. even increased libido Weightlifting has one of the lowest injury rates compared to other major physical activities, meaning people can train safely. low risk and high reward. With the increasingly sedentary but busy lifestyle that most people lead, they now have to make an effort to stay healthy. Accordingly, everyone should use their strength in order to have optimal time and cost-effective way. improve overall health and physical function.
