Can youth sports coaching improve the speed, agility and quickness of football players?

THE ELEMENTS OF FOOTBALL SPEED TRAINING:
STEP 1: Basic training. this step develops all qualities of human movement to a level that provide a solid base on which to build each successive step. It includes programs to increase body control, strength, muscle endurance, and sustained effect.

STEP 2: Functional strength and explosive movements against medium to heavy resistance. Maximum power is trained by working in an intensity range of 55 to 85 percent of your maximum intensity (1RM).

STEP 3: Ballistics. This step focuses on high speed sending and receiving movements.

STEP 4: Plyometrics. This rep focuses on explosive hoping, jumping, bounding, hitting, and kicking.

STEP 5: Sport loading. This step focuses on precision loading at high speed. The intensity is  85 to 100 percent of maximum speed.

STEP 6: Sprinting form and speed endurance. This step focuses on sprinting technique and improving the length of time you are abler to maintain your speed.

STEP 7: Over speed training. This step involves systematic application of sporting speed that exceeds maximum speed by 5 to 10 percent through the use of various over speed training techniques.
