Final answer:
Adults are likely to suffer from overuse injuries affecting muscles, tendons, and bones when resistance training is done incorrectly, leading to muscle soreness and potential tendon or skeletal damage.
Step-by-step explanation:
Adults engaging in resistance training are more likely to injure muscles, tendons, and bones if proper techniques and recovery periods are not respected. Overuse injuries often result from lifting weights that are too heavy, insufficient recovery time for muscle repair, or improper joint alignment during exercise. When muscles undergo intense exercise, cellular damage can occur, including to the sarcolemma and myofibrils, which leads to muscle soreness. Fortunately, as muscles repair this damage, they gain mass by adding new structural proteins. However, it's crucial to avoid overworking the skeletal muscles as this can cause tendon damage or even skeletal damage if the resistance involved is more than the muscles can handle. Proper exercise patterns are important for health and to prevent maladjustment of the body's musculoskeletal system.
