Why do sprinters start crouched?
The crouching position that modern starting blocks impose facilitates a horizontal surge of energy. This burst propels runners to higher speeds more quickly. Formerly, track stars dug holes for their toes in the dirt of the track to plant their feet for the start.
Keeping your head down allows you to more efficiently apply your power in a forward motion as opposed to an upward motion (the type of motion you get from running straight up).
The four-point start has you commence in a crouched position with both hands on the starting line, and your front knee leaning over the starting the line. Your back knee should be on the ground next to your front ankle. On the 'set' call, extend both knees so your hips are sitting just higher than your shoulders.
Pull the knees straight up, and do not allow them to angle towards the midline of the body. Run by striking the ground directly below the hips, particularly when accelerating. Run on the balls of the feet. Don't be flat footed and noisy.
The speed needs to be done at the beginning of a run, though, so that your legs are fresh and you can run fast. Doing sprints at the beginning of a workout (after a warm up, of course) can also help to lengthen your stride slightly, which can lead to a significant improvement in terms of speed.
The main starting positions of a crouched start state are bunched, medium, and elongated. The different sprint starting positions affect performance from push-off to the second step.
The answer to why races have staggered starts is simple: Math. If you're running in one of the outside lanes, you're running around a bigger oval -- the farther out you go, the longer you'd have to run if you were running a full lap. Races have staggered starts so that everyone is running the same distance.
The majority of distance runners are heel strikers. This is true regardless of elite or recreational status, with at least 70 percent hitting the ground first at the heel. This may be because heel striking has been found to be more energy-efficient at slow to medium speeds. Sprinters tend to land farther forward.
It's true: slow runs help make you faster on race day. We asked elite coaches and athletes to explain why. If you think elite distance runners are spending every training session pushing themselves at superhuman paces, think again.
Ground contact during accelerative sprinting
For faster sprint times it is important to limit the amount of time that your foot spends in contact with the ground during each stride. This is why sprinters run on the balls of their feet and sprinting spikes all have the spikes positioned on the forefoot.
What age should you stop sprinting?
Sprinting. While it's a good idea to periodically increase your workout intensity, adding sprints to a running or jogging routine could put you at greater risk for injury after 50, Holland says.

Peak period of a sprinter
By taking a closer look to this pie chart, it is quite evident that the vast majority of personal best records were achieved between 23 and 28 years. Between 24 and 26 years though, the relevant mean of annual best records is better than any other three – year period.
Sprinters should avoid eating high-fiber grains or vegetables, high-fat foods or large meals within several hours of training, as these can cause gastrointestinal fullness of discomfort.
Run tall with your head, neck, and shoulders in line with your hips. Move your arms front-to-back; don't let them cross your torso. Keep your elbows bent 90 degrees. Let your feet land directly beneath you; don't try to step too far forward. Run with a high knee lift.
The current evidence suggests that the hip extensors, hip flexors and knee flexors are the most important muscle groups for sprinters.
The 100m sprint has four distinct phases that should be addressed by the coach – the start, the acceleration phase, the transition phase and the maximum velocity phase (Winkleman, 2009).
Starting the sprint on Monday will tempt teams to work over the weekend to finish stuff that was not finished on Friday.
According to Watson, “Two week sprints mean we catch any potential issues faster. Getting feedback at the end of every sprint helps us shape the project moving forward, and ensures that everyone is on the same page, and working toward the same goal.”
The study found that skilled sprinters were 0.030 s faster to 50 m with a crouch start than an elongated standing start. However, unskilled sprinters were 0.043 s faster when using the elongated standing technique (feet were 0.46 m apart).
Who invented crouch start?
Bobby McDonald (Yorta Yorta)
In the late 1880s to early 1900s Bobby McDonald was a star runner, but more so, his ingenuity changed the sport of athletics forever. In 1887, McDonald developed what we now know today as the 'crouch start'.
The head should remain in a neutral position when in the set position, which will lead the eyes to be focused back behind the start line. This will help put the athlete in a more effective acceleration position in which the aim is to achieve a lean forward from ankles to ears.
"The first mile is the hardest because it leads to a rapid increase in oxygen demand to your entire body," says Sadi Raza, MD, FACC, a board-certified cardiologist in Dallas, Texas.
Running is also challenging for your muscles and joints, especially in your lower body. It takes time to build up the muscular strength and endurance in your legs, so your legs might hurt or feel completely fatigued when you first start running.
Accept that it'll always be hard, to some degree.
Also, every single time you begin a run, your body needs a little bit of transition time. Your heart beats faster and your blood vessels dilate to bring more oxygen into your blood, and then to your muscles.
