Question 1

Discuss the two important sprint techniques.

Answer 1

Frontside and backside mechanics are the two important aspects in sprint technique.
Frontside mechanics is about the triple flexion of the ankle, hip, and knee in the appropriate synchrony.

Improvements made in frontside mechanics sees better stability, less breaking force, and increases in forward driving forces.

Backside mechanics involve the same three triple extension aspects of the knee, hip, and ankle.
Improvements made in backside mechanic will see stronger pushing phases in the hip-knee extension, contraction of glutes, and backside arm drive.

Question 2

What are speed, agility, and quickness?

Answer 2

Speed: The ability to move the body in one intended direction as fast as possible.

• Agility: The ability to accelerate, decelerate, stabilize, and change direction quickly while
  maintaining proper posture.
• Quickness: The ability to react and change body position with the maximal rate of
  force production, in all planes of motion and from all body positions, during functional activities.

Question 3

What is SAQ training for seniors?

Answer 3

This is used for seniors in order to prevent decreases in bone density, coordinative ability, and muscular power due to age factors. This will aid in injury prevention and increase people’s quality of life. Some example SAQ drills are the varied size cone/hurdle step overs and stand-up to figure 8.

Question 4

Why should youth clients primarily use speed, agility, and quickness training?

Answer 4

The youth population should primarily perform SAQ training because it is shown to decrease the likelihood of athletic injury, increase the likelihood of exercise participation later in life, and improve overall physical fitness.

Question 5

What are the kinetic chain checkpoints when running?

Answer 5

Kinetic Chain Checkpoints
- Foot/ankle complex
- Knee complex
- Lumbo-pelvic-hip complex
- Head
