Final answer:
The assertion regarding the study of the musculoskeletal system by biokineticists, which includes force, leverage, and stability in human movement and sports, is true. Statics is vital in analyzing strains and understanding the mechanical advantages of muscle-lever systems, highlighting the biomechanical complexities within the human body.
Step-by-step explanation:
The statement that biokineticists study the musculoskeletal system and examine the production of force, leverage, and stability with respect to human movement and sport object motion is true. The study of these elements is crucial for understanding how the musculoskeletal system functions during various activities. Statics, for example, is a fundamental component in diagnosing the everyday strains in our muscles and bones. It highlights how many lever systems in our body, such as those involving muscles attached close to joints, have a mechanical advantage of less than one. This impacts the force that our muscles, such as the biceps, need to exert when performing actions like holding up a book. Bones also facilitate movement by serving as points of attachment for muscles and act as levers whereas joints operate as fulcrums, dictating that unless a muscle spans a joint and contracts, a bone will not move.
