100 metres needs timing, along with show jumping and cross country.
events get timed due to competition if you were up against several people you need to know the exact times of each person in order to give them a correct place.
Having a perfect timing is the key to achieve victory in the field of sport. Some of the examples of sport which requires timing are Baseball, Ice Hockey, soccer and even boxing.
Boxing, Athletics (sprinting) tennis, skiing, motor racing, offroading, motorcycling, all ball sports except golf and bowling, judo.
Hockey has 6 players on the ice at a time. Including the goalie. I can't think of any sport that would only have six. But hockey has six at a time.
The sport of cricket.
well I'm not really sure but i think it needs time to mix in with each other and then it will cause a chemical reaction.
Hockey
Golf.
Every sport requires skill levels and reaction times according to the level of opposition that is available in that sport at the time. In both - tennis and cricket the ball can hit something on the ground and bounce 'untrue'. Other than that, it depends on what is 'thrown' at them at the time.
Endothermic.
soccer, its vigorous!
cardio respiratory endurance muscular strength flexibility speed power coordination balance agility reaction time
tug of war
A reaction time is born but is made at the same time. While you grow older and use your reaction more, your reaction time will become faster and better. So, your reaction time isn't born nor made.
