Because he already has forward momentum.
Sir Isaac's first law: An object in motion, tends to stay in motion. If you try and jump from a stopped position you have to exert an enormous amount of energy all at once. According to Newton, if you are already moving then you don't have to exert that burst of energy all at once. If you add that energy all at once when you are already moving then it gets added to the energy of the existing motion.
If you are going to do this for a competition, than a mix of short distance timed running and long distance running. You should keep a mix of fast short exercises and longer distance ones.
ya it can help ...............
In long jump, momentum plays a crucial role in propelling the athlete forward and increasing the distance covered. The greater the speed and body mass of the athlete during takeoff, the more momentum they can generate for the jump. This momentum helps the athlete maintain their velocity in the air and cover a longer distance.
Depends on the kind of runner you are. Asics are generally lighter running shoes than most brands, so they are good for longer distance running sessions.
they allow an athlete to exercise longer.
The different types of running spikes available in the market include sprint spikes for short distance races, middle-distance spikes for races up to 1500 meters, distance spikes for longer races, and cross country spikes for off-road running. Each type is designed to provide specific traction and support for different running distances and terrains.
Momentum affect jumping a great deal, that is why a standing long jump is significantly less that one taken at close to maximum speed. Usually the faster an athlete the longer he or she will jump, but jumping also depend not only on speed but also on how the athlete converts that speed in the last couple of strides. A jumper can negate their running speed by slowing down at the board, lengthening the strides at the board or by dropping the hips too low.
You can be fast... 1. running 2. running away from someone that you don't like (ex. someone with a chain saw) (if you don't your a retard) 3. driving 4. biking away from the police 5. running from jail 6. running away from chocolate... I'm mean uh a stranger. 7. the real answer is practice (if your going to die from chuck norris)
They allow an athlete to exercise longer.
Soccer, because it requires more running for a longer period of time with almost no breaks. They must be able to jump with opponents for headballs, fight for possession of the ball and they must have tremendous footwork.
Leg length can affect running speed by influencing stride length, which is the distance covered with each step. Longer legs can potentially lead to a longer stride length, allowing for greater speed. However, factors such as stride frequency, muscle strength, and technique also play important roles in determining running speed.
