Answer: Yahh, A good warm up helps to prepare your mind and body for the increased demands of exercise. Warming up:
Raises your body temperature. Warm muscles absorb shock better and are more elastic, therefore helping to reduce injury rate
Prepares your cardiovascular system (heart, lungs and blood vessels), gradually increasing circulation, preventing a rapid increase in blood pressure and helping to distribute oxygen and nutrients more effectively
Triggers processes in the body such as sweating and increased breathing rate which prevent you overheating during the game
Puts your head in the game! It gets your brain switched on to the upcoming task
Wakes up your nerve pathways (the messages from your brain to your muscles) for the specific movements required in a game
Improves coordination and reaction times – you’re more likely to get that shot on target! It should raise your heart rate and warm you up without making you too tired for the game ahead. Ideally, you’ve built up a light sweat and increased your breathing rate
