2. describe how the warm up and cool down exercises relate to the principles of biomechanics and human anatomy and physiology. Give several examples to illustrate your point.
Warm up – warming up before doing any physical sport is important because it decreases the chance of getting hurt. It increases your blood temperature which increases the blood flow. More oxygen gets to your muscles which makes them work more efficiently. It also increases muscle temperature so it can contract and relax easier. This means better performance and less chance of injury. Always stretch after warm-ups. It is normal to have a light sweat to cool your body down. It is important to not over heat and to keep hydrated by drinking lots of water. Warm-up can include, relays, passing and skills or races.
Cooling down after physical activities reduces blood flow gradually to the working muscles. It also reduces the heart beat, blood temperature and muscle temperature. A cool down can also help with recovery and alos prevents injury later on. Gentle static and dynamic stretching could be a cool down. A slow gentle cool down help the muscles get rid of lactic acid and waste products and yeah.
3. describe how to prevent or manage injuries when conducting warm up and cool down exercises. What might be the contraindications or precautions for warm up and cool down exercises.
To avoid getting any injuries during a warm up or cool down you must always stretch after each warm up or cool down. Dynamic stretches are an example of stretches you could do. You shouldn’t stretch before a warm up because you muscle would still be cold. A warm up should start light and then gradually increase. Try not to bounce when stretching. If you are in cold weather, a longer warm up is recommended. You must always, at al time stay hydrated and drink lots of water. Before any stretching it is important to increase your heart rate with a warm up first.
