What are the responses of the muscular system to a single exercise session? | Increased blood supply. Increase in muscle temperature. Increased muscle pliability. Lactate accumulation. Microtears. DOMS. |
What does blood carry? | oxygen |
What is oxygen needed for? | energy |
What is there an increase in demand for when we exercise? | oxygen & glucose in the muscles |
What is vasodilation? | blood vessels expand to allow more blood to enter the muscles |
What is created when we produce energy for exercise? | heat |
Why should you do a warm-up before exercise? | to prepare your muscles by slowly increasing their temperature |
What does warming of your muscles do? | makes them more pliable and flexible |
Why do muscles need to be pliable? | they will be less likely to suffer injuries e.g muscle strains |
What does an increase in muscle pliability improve? | joint flexibility as pliable muscles can stretch further |
What is lactic acid? | a waste product produced during anaerobic exercise |
What does lactic acid cause? | rapid fatigue & can impede muscular contractions |
What are microtears? | tiny tears in the muscle fibres |
What is DOMS? | Delayed onset of muscle soreness |
When does DOMS happen? | 24-48 hours after strenuous exercise |
How long does DOMS last? | up to 3 days |
What causes DOMS? | microtears |
