What is the role of the skeletal system in movement?
✔✔The skeletal system provides structure, support, and acts as a framework for muscles to
generate movement.
How do ligaments contribute to joint stability?
✔✔Ligaments connect bones to each other and help stabilize joints by limiting excessive
movement.
What is the difference between voluntary and involuntary muscle contraction?
✔✔Voluntary muscle contractions are controlled consciously, while involuntary contractions
occur automatically without conscious control.
How do muscle fibers respond to resistance training?
✔✔Resistance training leads to muscle hypertrophy, where muscle fibers increase in size and
strength due to the overload principle.

,What is the role of the cardiovascular system during exercise?
✔✔The cardiovascular system delivers oxygen and nutrients to muscles, removes waste
products, and regulates body temperature during exercise.
How does aerobic training improve heart function?
✔✔Aerobic training increases stroke volume, reduces resting heart rate, and improves the heart’s
efficiency in delivering oxygenated blood to the body.
What is the difference between fast-twitch and slow-twitch muscle fibers?
✔✔Fast-twitch fibers are suited for explosive, short-duration activities, while slow-twitch fibers
are better for endurance, long-duration activities due to their resistance to fatigue.
How does the body respond to dehydration during exercise?
✔✔Dehydration reduces blood plasma volume, impairing circulation, thermoregulation, and
performance, leading to earlier fatigue and increased risk of heat stress.
What are the functions of red blood cells in exercise?
✔✔Red blood cells transport oxygen from the lungs to muscles and remove carbon dioxide from
muscles to the lungs for exhalation.
2
, How do the respiratory muscles facilitate breathing during exercise?
✔✔The diaphragm and intercostal muscles contract to increase lung volume, allowing more
oxygen to enter and more carbon dioxide to exit during exercise.
What is the role of the nervous system in controlling movement?
✔✔The nervous system sends electrical signals to muscles to initiate and coordinate movement,
allowing for precise control and adaptation to external stimuli.
How does the body increase blood flow to muscles during exercise?
✔✔The body increases blood flow to muscles by vasodilation of blood vessels supplying the
muscles and vasoconstriction of vessels in less active areas.
What is the function of the endocrine system during exercise?
✔✔The endocrine system releases hormones like adrenaline and cortisol to regulate metabolism,
energy production, and stress responses during exercise.
What is the role of ATP in muscle contraction?
