Bounding versus sprinting they are not the same stick drill
Video demonstrates why bounding and sprinting are not the same. Using stick drill to demo.
A x M = F work best.
Pushing is not the best way to sprint at your optimal best.

Asymmetrical arm swing versus linear arm swing when sprinting video
This video is an excerpt from a track and field seminar put on by AUC Elite. The video is about asymmetrical arm swing versus linear arm swing while sprinting.
Foot and leg action block start
Why is Usain able to win this race? From the get go he is able to accelerate his feet faster than Gay. Gay would do better if he didn't reaccelerate his feet every step for the first 10 steps. You wonder why a guy with longer levers can out run a guy with shorter levers from the blocks, this video shows how and why.

This is what exploding from a start looks like
This what you should look at when exploding from a starting position. This is base on using A x M = F.So the body becomes unstable and react forcefully to become stable in the air and upon ground contact.
Prevent hamstring injuries with A x M = F
The tremendous forces
The diverse nature of running events (sprints and hurdles, to marathons) can put runners at a high risk for injuries.
The tremendous forces generated by a sprinter out of the starting blocks place significant stress upon the knee joint, the hamstrings, and the quadriceps. From the crouched position of the start, where the hamstrings hold the knee in the flexed position, the quadriceps will extend the knee explosively at the start and drive the legs forward. It is a well-accepted principle of biomechanics that the ideal proportion in the relative strength of the quadriceps to the hamstring will be approximately 3:2. When this ratio is not observed (generally the hamstring will be weaker of the two structures), the risk of a serious hamstring pull or tear is significant.

A x M = F
This simple equation is the key to unlocking your true potential in track and field.
Force application is the word of the day but it should be acceleration. Applying more fore is not the issue, accelerating is the issue. The faster the acceleration, the greater the force one can apply at ground contact.
This equation works also for every single event in track and field.

Hurdling tip
To hurdle faster and speed up between the hurdles. Accelerate the lead arm backwards and the trail leg forward. You must do both action. Only concentrating on brining the trail leg forward places too much stress on the hip flexors and it is a slow action which does produce much force upon the foot contacting the ground.
Also have the elbow and hand of the lead arm past over the knee and foot of the trail leg almost touching each other. This will create better balance in the air allowing for the hurdler to regain stability faster upon contacting the ground.

asymmetrical training
Asymmetrical training is different than bilateral training or unilateral training. With asymmetrical training each part of the body, each muscle has its own job to do. It’s not the same job as the opposite arm, opposite leg, opposite eye; it has its own job. With bilateral training say you’re doing something with the left and right hand or left and right or left and right leg, they’re both doing the same thing at the same time. Unilateral training involves a single arm or leg type exercise. Most people do unilateral training to try and balance out one side versus another side when they find an asymmetrical difference. For us asymmetrical differences are good. It’s how the body operates at its peak efficiency and it’s very proficient at what it does, which is movement. So asymmetrical training in the form of performance training and exercise training is much different than bilateral training or unilateral training.

Long jump approach
The first six steps to jumping far
The long jump approach is difficult to master. The ability to attain top horizontal speed (velocity) that can be transferred into vertical speed at take-off while maintaining maximum horizontal speed is the difference between a far jump and a not so far jump. A good approach is one where the jumper loses very little horizontal speed at take-off, since the distance of the jump is pre-determine at take-off. Runway speed is different than track speed; the jumper must not only get up to top speed but also must be able to maintain that top speed for the whole approach.

Linear arm movement and sprinting
This is my position on linear arm movement and spritning and running.
I have to alter my stance on lifting of the knee while sprinting and running, If you use linear arm movement then you must lift your knees and pull them through. You must doris flex the toes, you have to pick them up and put them back down. As this is vertical running/sprinting, so yes you must increase vertical displacement to maintain top end speed. As this style of running/sprinting is turnover base and not stride length base.
I am not a fan of linear arm movement as I don't think it is the most efficient way to run or sprint and it comes with to many instructions and cues.

Sprinting and leg swing speed
When they talk about how leg swing speed is the same regardless of how fast or slow the person is;
do they look at the speed at which the legs folds up or the completeness of knee flexion or do they look at just the length of time it takes for the foot to touch down again?
As the speed at which it folds up will have a big impact on stride length.
What if your muscle recruitment pattern during running and sprinting does not involve using the calf muscles( gastrocnemius) to help with knee flexion, As the gastrocnemius are what 80 percent type II fibers. If that is the case then those that use the gastrocnemius automatically are at a distinct advantage over those that do not.
